Patent No. 3625399A: Automatic Carbonated Beverage Dispensing System

By

patent-logo
Today in 1971, US Patent 3625399 A was issued, an invention of Noel D. Heisler, assigned to the Schlitz Brewing Co., for his “Automatic Carbonated Beverage Dispensing System.” There’s no Abstract, although in the description it includes these claims:

In general, the invention is directed to an electrical release or dispensing system for a plurality of carbonated beverages stored in suitable containers where it is desirable at a remote distance therefrom to initiate the dispensing of the beverages from another and successive container when the container from which the beverage being dispensed is empty. The system provides a header which is connected to the containers to be emptied by separated conduits in which are located solenoid liquid valves. These valves are separately actuated from a selector control unit to open a respective conduit from a container to the header and then to to a tap. A second header is connected to a source of Co gas and flow of gas from the header to the containers are through separate conduits to each container. Solenoid fluid valves are located in each gas conduit and are individually actuated to control the flow of gas to the container being tapped. The opening of a respective fluid solenoid valve occurs simultaneously with the opening of a corresponding liquid valve An important feature of the invention is that the dispensing valves are opened by momentary high surge of current to seize the solenoid armature and are held in the open position by a low holding current. The holding current consumes less power and consequently gives off less heat. In an alternative construction, the liquid dispensing valves may each be dual winding units having an opening winding and a holding winding. The holding winding draws a lesser current and consequently also minimizes generation of heat. Excessive heat is deleterious to the carbonate beverage being dispensed.

Patent No. 5473161A: Method For Testing Carbonation Loss From Beverage Bottles Using IR Spectroscopy

By

patent-logo
Today in 1995, US Patent 5473161 A was issued, an invention of John A. Nix, Stephen W. Zagarola, and Louis Jolie, for their “Method for Testing Carbonation Loss from Beverage Bottles using IR Spectroscopy.” Here’s the Abstract:

A method for measuring carbonation loss in beverage bottles and predicting shelf-life thereof utilizes infrared (IR) absorption spectroscopy. The concentration of CO2 gas in a bottle being tested is measured with an infrared beam according to Beer’s Law. In one embodiment the CO2 gas measured is in the headspace of a test bottle partially filled with carbonated water. The walls of the bottle are clamped in a fixture to maintain the bottle diameter substantially constant. An IR beam is transmitted through the bottle just below the fixture, and absorption values of the beam are measured. Shelf-life is calculated from the absorption values. In another embodiment the test bottle is filled with compressed CO2 gas generated by dry ice placed in the bottle.

Patent No. 197744A: Improvement In Hop-Vine Stripper And Separator

By

patent-logo
Today in 1877, US Patent 197744 A was issued, an invention of Moses C. Smith, for his “Improvement in Hop-Vine Stripper and Separator.” There’s no Abstract, although in the description it includes these claims:

This invention is in the nature of an improvement in machinery for picking or stripping hops from their vines for separating the hops from the vine-leaves; for separating or breaking up bunches or clusters, and for delivering the hops into bags ready for the kiln, the said machinery being portable, and designed for use in the field.

The invention consists in rolls of soft yielding material for feeding the vines to the stripping mechanism; of moving stripping-teeth disengaging the hops from the vines as they are fed forward, and carrying said vines forward; of a table beneath said moving teeth for receiving the vines from the feed-rolls, and made yielding, so as to avoid choking by accumulation of the vines; of a toothed revolving apron, operating in connection with a toothed bar, for delivering said hops into a chute, from which they are discharged into bags in condition for the drying-kiln, these several elements being combined as hereinafter claimed.

The invention further consists, in connection with the above-described or equivalent mechanism, in a fan located in the forward end of the machine; a fan-hood, the throat of which is guarded by a number of tongues depending from the yielding table before described, to prevent the escape of hops and leaves into the fan-casing; a perforated apron moving over rollers, and. a shaker or sieve placed beneath the said apron, and over the and the perforated apron, over which the vines pass, and between which the hops fall onto the toothed apron.

The invention also consists in arms or rests secured to the frame of the machine, and projecting laterally therefrom at either side of the feed-opening, for the purpose of permitting the stacking of the hop-poles, with the vines thereon, in convenient reach of those feeding the machine.

Patent No. 1046298A: Beer Cooler

By

patent-logo
Today in 1912, US Patent 1046298 A was issued, an invention of John W. Hurley, for his “Beer Cooler.” There’s no Abstract, although in the description it includes these claims:

This invention relates to beer coolers.

The ordinary beer cooler coil which is usually made of block tin is subject to numerous objections, among which may be mentioned its short life, difficulty in cleaning, tendency to accumulate impurities which contaminate the beer passing there-through, difficulty in detaching and removing it from its place in the cooler box, and its pitting and disintegration by the ammonia in the ice water. Among its other defects is its relatively great expense and necessity for comparatively frequent renewal, aside from being insanitary.

My invention has for its object the provision of a beer cooler of simple, strong and durable construction which may be inexpensively manufactured and installed, either originally when the beer dispensing apparatus is put in, or subsequently to supplant a coil cooler. A further object is to provide an improved beer cooler which can be readily taken apart and quickly washed and cleaned, will not be liable to injury, as is the case with cooler coils, will not be subject to disintegration by the action of ammonia, will at all times afford a free and easy circulation for the beer and the ready disposal of the ice about the beer cooler and the flow or circulation of the ice water therethrough.

Patent No. D48217S: Design For A Drinking Glass

By

patent-logo
Today in 1915, US Patent D48217 S was issued, an invention of Frederick E. Anderson, for his “Design for a Drinking Glass.” There’s no Abstract, although in the description it includes these claims:

I have invented a certain new, original, and ornamental Design for a Drinking-Glass, of which the following is a specification, reference being had to the drawings forming a part thereof, wherein the side wall of the drinking glass is substantially straight from its lower end upwardly to a point near its top edge, at which point a pronounced outward curvature is developed in the form of a concavo convex bulge. This rounded or bulged formation is comparatively shallow vertically and terminates in the top edge, which edge is substantially in the plane of the straight side wall portion. It is thus characteristic of the design that the side of the glass presents a substantially straight line from its bottom to its top edge, save the outward bulge-which is adjacent to the top.
