Patent No. 5334400A: Beverage Package

patent-logo
Today in 1994, US Patent 5334400 A was issued, an invention of Robert Purdham, assigned to Guinness Brewing Worldwide Limited, for his “Beverage Package.” Here’s the Abstract:

A sealed beverage package has a bottle 1, a neck 4 of which provides a narrow mouth 5. A hollow insert 7 is submerged in beverage 13 in the bottle. A headspace 14 in the bottle is at a pressure greater than atmospheric and when the package is opened to de-pressurise the headspace 14, gas and/or liquid under pressure in the insert 7 is ejected through an aperture 8 into the beverage to cause a head of froth to develop on the beverage 13. The insert 7 is retained in position by an open framework 9 of struts 10 which extend between the insert and a retaining ring 11 that frictionally engages in a bore 6 adjacent to the mouth 5 of the bottle. The insert 7 can be attached to the framework 9 or formed integral therewith.

It’s also described thusly:

The present invention relates to a beverage package and a method of forming such a package. More particularly it concerns a sealed package of the kind containing beverage having gas in solution and within which beverage is located a hollow insert containing gas under pressure which, upon opening of the package, causes a gas and/or liquid to be ejected from the insert by way of a restricted orifice to cause, or assist in, the formation of a head of froth on the beverage by the evolution of gas dissolved therein. The ejection of the gas and/or liquid from the hollow insert results from the opening of the package when a headspace of the beverage which, in the sealed package, is at a pressure greater than atmospheric rapidly reduces to atmospheric pressure so that a pressure differential is created which permits the gas and/or liquid under pressure greater than atmospheric in the insert to be ejected into the beverage in the container.

Patent No. 2756917A: Valve For Counter Pressure Filling Apparatus

patent-logo
Today in 1956, US Patent 2756917 A was issued, an invention of John T. Kline, for his “Valve For Counter Pressure Filling Apparatus.” There’s no Abstract, although in the description it includes this summary:

Briefly outlined they are as follows: The charged liquid is supplied to a reservoir by piping connected to a continuous source of supply forming a closed circuit; air or gas under pressure, such as carbon dioxide, is also supplied to the reservoir by suitable piping leading from a continuous source forming a closed circuit, thereby providing a head above the liquid in the reservoir; and a plurality of filling heads, each one of which contains a rotary fiat valve and means to temporarily seal the containers, is joined to the bottom of the reservoir and connected with the interior thereof by suitable piping to permit removal of the liquid and/ or the air or gas confined therein. By positioning the valve in each filling head in a predetermined pattern, a filling sequence is accomplished which permits the filling of the containers without excessively foaming or effervescing the liquid. This sequence consists of temporarily sealing the container to the filling head; then positioning the valve to permit the air or gas under pressure in the reservoir, commonly called counter pressure, to enter into the container to equalize the pressure between them; then positioning the valve to permit the liquid in the reservoir to enter into the container under its normal hydrostatic pressure and to return the air or gas (counter pressure) in the container back to the reservoir as it is being displaced by the liquid; then positioning the valve to out off the flow of the liquid and the air or gas (counter pressure) to and from the container; then exhausting any air or gas remaining in the container and finally permanently sealing the container.

My invention, while relating generally to apparatus for transferring gaseous liquids from a source of supply to containers, specifically relates to the rotary fiat valve employed by such apparatus and is specifically directed to the method employed in conveying the liquid and air or gas from the reservoir to the container.

Patent No. 1235231A: Apparatus For Cooling And Rousing Beer-Wort And For Precipitating Sludge From Same

patent-logo
Today in 1917, US Patent 1235231 A was issued, an invention of Leopold Nathan, for his “Apparatus for Cooling and Rousing Beer-Wort and for Precipitating Sludge from Same.” There’s no Abstract, although in the description it includes this summary:

In the brewing of beer, especially in breweries in which special stress is laid on the production of high-class beers, the cooler is still in almost general use for cooling down the worts. The cooler, however, constitutes the primary and worst source of infection in the preparation of beer. Owing to the very rapid cooling of. the wort in the cooler, germs which have settled down on the cooler before it is charged with wort are not all killed. Moreover, fresh germs make their appearance during the cooling process, and these are not killed, especially at temperatures from 60 downward.

In spite of these defects of the cooler, it has been impossible hitherto, owing to its valuable properties for certain special types of beer, to dispense with this appliance. In addition to the cooling effect produced in the cooler, vapors are eliminated which carry off with them unpleasant odors formed in consequence of the inevitable access of air. Through the access of air and simultaneous cooling, considerable quantities of protein substances and hop resins are precipitated, and the only way in which these can be separated from the liquid is by allowing them to settle down, for which purpose the extensive surface of the cooler is highly advantageous.

The method employed by me in connection with the apparatus of the present invention consists in the first place in freeing the wort from the said aromatic and flavoring substances by the passage of a current of air or carbon dioxid, or both. If, as was hitherto the case, in this treatment the gas be forced or drawn into the wort from below, a very strong frothing is produced, which prevents the complete removal of the vapors.

The operation is directed, in the first place, to preventing this frothing or to nullifying its ill effects. With this object, the gas is carried, in a powerful current, along the wort in a finely-divided state so as to carry off the vapors from the surface of the liquid. At the same time a cooling effect is also produced; nevertheless the essential portion of the elimination effect can only be accomplished fully by treating the hot wort with a current of gas. The complete deposition of the cooler sludge, occurring as cooling progresses, is facilitated in a special manner, and the possibility of carrying it out in a closed, sterile vessel is afforded, by setting up in said vessel a frame containing a large number of superimposed stages having a total superficial area corresponding to that of the cooler. In order to remove the sludge this staged frame must be taken out of the vessel. The resulting infection is neutralized by allowing the next charge of wort to run into the vessel in a sufficiently hot condition.

This operation can be carried out in two vessels: one for the elimination treatment and one for the deposition of the sludge; or one and the same vessel may be used for both purposes.

Patent No. 533747A: Beer-Cooling Device

patent-logo
Today in 1895, US Patent 533747 A was issued, an invention of Otto Ritter, for his “Beer-Cooling Device.” There’s no Abstract, although in the description it includes this summary:

My invention relates to a beer cooling apparatus, the object of my invention being to so construct an apparatus as that when the wort or beer is passed through said apparatus it will operate a fan, which fan by its rotation sprays and cools the beer.

A further Object of my invention is to so gear the fan upon the central shaft as that said fan will rotate with greater rapidity than does the shaft.

My improved beer cooling apparatus is adapted to be located in an inclosure which is generally located in the top of brew houses, the beer being forced to said inclosure by a pump, or other suitable means, there to be passed through the apparatus and into the vats or pans adapted to receive it.

My invention consists in a suitable hollow casting adapted to besnpported in a position above the beer cooling receptacle, a shaft mounted vertically in said casting, a series of discharge nozzles or apertures located in said casting, a motor or turbine-wheel mounted to receive the beer that is discharged from said nozzles or apertures and to be revolved by the pressure of the beer, anda fan driven by and located below the said motor or turbine wheel in position to receive the beer sprayed above said fan by the movement ot’ said parts.

patent-logo
Today in 1973, US Patent 3749004 A was issued, an invention of William G. Pagdin and Charles F. Constable, assigned to the Schlitz Brewing Co., for their “Apparatus for Crushing and/or Compacting.” There’s no Abstract, although in the description it includes this summary:

The invention relates to that type of crushing and/or compacting machine or apparatus wherein a plurality of sets or pairs of opposing crushing rollers are arranged in series. Broadly according to the invention, a frame rotatably supports one roller from each set of rollers. The other roller from each set of rollers is rotatably supported by a member movable relative to the frame and the frame supported rollers. The rollers supported by the movable member move with that member relative to the frame supported rollers to provide for relief from shock loading between the sets of opposing rollers. Relative movement between the opposing rollers to relieve shock loading there between is resisted by resilient means.

Patent No. 1138251A: Mash-Filter Plate

patent-logo
Today in 1915, US Patent 1138251 A was issued, an invention of Joseph Schaefer, for his “Mash-Filter Plate.” There’s no Abstract, although in the description it includes this summary:

My invention relates to mash filters adapted for use in the arts of brewing, distilling or in the manufacture of compressed yeast, and in part is a continuation of my sugars and soluble matter are more completely removed from the lower part of the grains cakes because of the greater water pressure in the lower part of the frames. This results in the loss of more or less of the valuable sugars unless an excessive amount of water is used. The use of too much water is not desirable since this dilutes the wort to such an extent, that, to remove the excess of water, extended boiling is required which, it should be understood, is expensive and detrimental to the final product. To overcome these objections I have arranged the water chambers so that the grains cakes formed there between will be thicker at the bottom than at the top, or substantially trapezoidal in shape. It has been found that with cakes of this shape the sparging 18 more thorough, and with the use of a given quantity of water-the soluble sugars are more formaly and completely removed from the grains cakes.

Another object of my invention is .to facilitate the removal of the grains cakes from their frames when the sparging process is completed, and the series of frames are separated for this purpose. The frame as ordinarily constructed is provided with a flat floor or bottom from which ‘it is difficult to dislodge that part of the cake resting on the bottom, it usually being necessary’ for the workman to scrape it of with a paddle or other device. With my improved construction I overcome this objection by constructing the bottom or floor of each grains cake frame, wedge-shaped or like a tool edge in cross-section. This construction is adapted to save the time of the workman for, as the grains cakes are friable, it will be seen that a mere tap of a hammer will cause the bottom of the grains cake to separate and slide down on each side of the wedge-shaped bottom of the cake frame, and thus leave the frame clean without any further effort on the part of workman.

Patent No. 3594995A: Hop-Picking Machine

patent-logo
Today in 1971, US Patent 3594995 A was issued, an invention of Thomas Lee Evans and Charlie J. Soules, for their “Hop-Picking Machine.” There’s no Abstract, although in the description it includes this summary:

This invention relates to hop-picking machines and, more particularly, to novel, improved machines for field picking hops from vines hanging from overhead wires or trellises or other supports.

We have now developed a novel, improved machine for filed picking hops which does not have the drawbacks of machines heretofore proposed for this purpose and accordingly represents a significant advance in the art over the latter. The novel hop-picking machines of the present invention are preferably self-propelled and, generally speaking, include graspers for engaging the lower ends of the vines and maintaining them in picking position as they move through the machine, picking cuts for stripping the hops from the vines, a conveyor arrangement for carrying the hops away, a cutter for severing the vines to free them from the supports, and an arrangement for expelling picked vines from the machine.

One of the important advantages of the novel hoppicking machine described herein is that, being self-propelled, it can be maneuvered through a field more easily and much faster than the cumbersome pushed-type” picker described in the Horst patents identified above and is accordingly capable of picking hops at a much higher rate. Another advantage, also resulting in increased capacity, is that the machines of the present invention are capable of picking two rows of vines simultaneously in contrast to the patented Horst machines which are single-row pickers.

In the Horst machines, the vines are pulled down through the machine as they are picked. Accordingly, a field hand must accompany the machine and cut the vines free from the trellises as they move into the machine. Applicant’s novel machine in contrast does not depend on downward movement of the vines they are picked; and, moreover, it is provided with its own cutter for severing the vines to free them from the trellises. Accordingly, the necessity of employing hand labor for this purpose is eliminated by the present invention together with the attendant expense.

In conjunction with the foregoing, another novel and important feature ofthe present invention is that the picking cats are vertically adjustable. This makes it possible to quickly adjust the cats as the heights of the overhead supports change so that the vines can be picked clean up to the supports.

Another important feature of the present invention is a novel conveyor for the hops stripped from the vines which normally discharges into a truck or the like but can be employed to store picked hops so that the machine can continue to pick while a loaded truck is being replaced or the machine is turning at the end ofa row, etc. In similar circumstances the picking operation would have be stopped in heretofore proposed machines such as those .described in .the Horst patents, for example.

Yet another important feature of the present invention is a novel grasper line for holding the vines in the proper position for picking in which the grapsers are moved at a speed matching the ground speed of the picking machine. Further, the grapscr line is configured to compensate for sagging vinesupporting wires, thereby ensuring that the vines are grasped at the proper location.

Other important features of the invention are a novel cutter mechanism for severing the vines and freeing them from the trellises and a novel mechanism for expelling the picked vines from the machine. Yet another novel and important feature of the invention is that the operating mechanisms are powered entirely by hydraulic motors, substantially eliminating belt and chain and similar drives. This makes the novel machines disclosed herein significantly simpler than comparable prior art harvesters.
