Patent No. 5676369A: Method Of Playing A Brewing Game

By

patent-logo
Today in 1997, US Patent 5676369 A was issued, an invention of Mark Keathon DeWeese, for his “Method of Playing a Brewing Game.” Here’s the Abstract:

A method of playing a board game related to brewing procedures and the science of brewing. The game includes a board having an endless path divided into a plurality of continuous spaces including a starting space and spaces with indicia upon them corresponding to hops, barley, yeast, brewing science and speciality beer styles. At least two players start by moving their playing pieces along a path according to a roll of the die. Upon landing on a space, a player must pick a card corresponding to that space. The card may require the player to correctly answer a question or may award or hinder his progress in the game. If the card requires an answer, which is correctly answered, the player is allowed to roll again and continue around the board. Upon passing the starting point the player is awarded a piece of brewery equipment. Players continue collecting brewing equipment while moving around the board. Play is terminated when a player receives all of the equipment necessary to operate a brewery.

The finished game was released. I have a copy of it, though I don’t recall where I got it. I think I only tried it one time, and I honestly don’t remember how it played, which I suppose in and of itself isn’t a ringing endorsement.

Patent No. 438328A: Apparatus For Brewing

By

patent-logo
Today in 1890, US Patent 438328 A was issued, an invention of William J. Seib, for his “Apparatus For Brewing.” There’s no Abstract, although in the description it includes this summary:

My invention relates to an improvement in apparatus for use in collecting, condensing, and storing the essential oil and aromatic properties of hops to save them, and which is, therefore, especially serviceable for the particular purpose for which I have invented it namely, that of saving the aforesaid properties of the hops while they are being boiled with the wort in the manufacture of beer.

My present invention is particularly designed to afford an improvement in the construction of an apparatus for the same purpose as that set forth in the application of Carl Hoefner for Letters Patent of the United States No. 301,482, allowed on the 22d day of March, 1890. The construction of the apparatus therein described necessitates that the vapor from the kettle shall pass to the condenser and return by the same course to the storage-reservoir, which impairs the effectiveness of the condensation, since the liquid thereof has to pass under the influence of the rising heated vapor to gain access to the receptacle.

My object is to provide an apparatus for the purpose stated whereby this objection shall be obviated; and to this end my invention consists in the construction hereinafter set forth and claimed.

Patent No. EP0949328A1: Gluten-Free Beer Containing Rice Malt

By

patent-logo
Today in 1999, US Patent EP 0949328 A1 was issued, an invention of Marina Pieranna Bellini, Francesco Collavo, Giovanni Maccagnan, Antonio Pat, and Gian Luca Ragg, assigned to Heineken Italia S.p.A., for their “Gluten-Free Beer Containing Rice Malt.” Here’s the Abstract:

A gluten-free beer obtained from a mixture of starting materials comprising buck wheat, rice malt and optionally a component chosen from the group comprising corn, sorghum, millet and/or syrups thereof; this component is preferably corn syrup; the beer is obtained by saccharifying the above-mentioned mixture, optionally in the presence of amylolytic enzymes and glucanase, and it is particularly suitable for consumption by gluten-intolerant individuals.

Surprising this patent was issued in 1999, a bit before gluten-free became “a thing.” I was taking classes at UC Davis when Anheuser-Busch was sending samples of their gluten-free Redbridge to Dr. Michael Lewis, who had recently discovered he suffered from celiac disease. I ended up doing an article about the science behind gluten-free beer for Zymurgy magazine and did a tasting of gluten-free beers for it at Davis right after A-B debuted Redbridge, and that was in 2006. As far I know, I haven’t seen a gluten-free beer from Heineken, although I seem to recall that their beer is low in gluten.

Patent No. 2057231A: Beer Faucet

By

patent-logo
Today in 1936, US Patent 2057231 A was issued, an invention of Lester J. Dawson, for his “Faucet.” There’s no Abstract, although in the description it includes this summary:

This invention relates to new and useful improvements in faucets, and more particularly to faucets especially designed for dispensing gaseous liquids such as beer. An object of the present invention is to provide a beer faucet of simple and inexpensive construction comprising a valve mounted for reciprocal movement which, when opened, is i entirely out of the beer stream so that the beer may flow unobstructedly through the valve substantially without agitation. A further object is to provide a beer-faucet provided with a suitable dispensing nozzle and having a passage therein adapted to be connected to aL beer supply under pressure and a valve being interposed between the beer nozzle and said passage for controlling flow through the nozzle, said valve being so constructed and arranged that the pressure of the carbon dioxide and other gas content of the beer will tend to hold the valve on its seat when closed.

Patent No. 7810679B2: Beer Dispensing System With Gas Pressure Reservoir

By

patent-logo
Today in 2010, US Patent 7810679 B2 was issued, an invention of Albert W. Wauters, Ian Anderson, and Edward P. Duffy, assigned to Anheuser-Busch Inbev S.A., for their “Beer Dispensing System with Gas Pressure Reservoir.” Here’s the Abstract:

A home beer dispensing apparatus has a keg having a self-contained bag filled with a beer and a pressure system. The pressure system creates a pressurized air space between the keg inner walls and the bag to assist in the dispensing of the beer. The pressure system has a keg one-way air valve mounted to a top wall of the keg to permit entry of pressurized air into the keg. The pressure system has a pressure reservoir mounted in the dispensing apparatus outside the keg and in fluid flow communication with the keg one-way valve. The reservoir stores a charge of pressurized air and supplies at least a portion of this charge to the keg through the keg air valve when the dispensing apparatus is operated to dispense the beer. The reservoir provides a reserved charge of pressurized gas that is on hand to reduce dampening pressure fluctuations during beer dispensing which can result in beer frothing, especially during the early stages of beer dispensing when the air head space in the keg is small. Further, the apparatus may also have a pressure sensing system adapted to measure time rate of pressure change in the keg. The apparatus has a signaling device responsive to the time rate of pressure change in the keg to produce a signal related to volume of beer remaining in the bag. Preferably, the signal is displayed visually on the dispensing apparatus.

Patent No. 2451273A: Method Of Applying Bottle Caps

By

patent-logo
Today in 1948, US Patent 2451273 A was issued, an invention of Elvin M. Bright, for his “Method of Applying Bottle Caps.” There’s no Abstract, although in the description it includes this summary:

This invention relates to improvements in a method for thermoplastically capping bottles.

It is an important object of the invention to provide a method and means of capping a bottle which, to a large extent, will make use of standard existing bottle capping equipment and will provide a cap which will not interfere with the handling, processing, merchandising, and use of the bottle and its contents in accordance with conventional procedure.

From the standpoint of the process involved, a very important objective is to soften a thickened margin of the bottle cap blank without softening the remainder thereof, and to mold such thickened margin around the cap-receiving bead of the bottle and immediately to harden it thereon. In this connection I propose to utilize infra-red rays or other radiant heat for softening the flange of the bottle cap blank while shielding and thermally insulating the top of the blank from such rays. Infra-red rays are preferred because of the ease with which they may be directed and controlled.

Patent No. 2331556A: Process For Purifying Wort

By

patent-logo
Today in 1943, US Patent 2331556 A was issued, an invention of Hans Olof Lindgren, for his “Process For Purifying Wort.” There’s no Abstract, although in the description it includes this summary:

The object of the invention is to provide a method of purifying, cooling, and aerating the wort, the main part of which is carried out as a continuous process, which is free of the above objections. The warm Wort leaving the hops boiler, at a temperature which is usually above 85 C. (185 FJ, and which should not be below ’70 C. (158 F.), or above 100 C. (212 F), is strained with a view to removing the coarsest impurities. It is then purified in a centrifuge f1 om which the purified Wort is discharged continuously. The wort is then passed through a cooler of such a construction that it cannot therein come into contact with the atmosphere. The cooled wort is conveyed to tanks, e. g., similar to the fermenting vats above described, in which the cool sludge is removed from the wort by finely divided air which has been mixed therewith at some step of the Process at which the wort is hot enough to sterilize the air, and which in the tank 6 lifts the .cool sludge to the surface. The air and the impurities, together with a small amount of wort, there form a layer of froth which may be skimmed off. If a suitable amount of air is used, a satisfactory purification is obtained at the same time, as the amount of wort contained in the froth is so small that it is unnecessary to take any measures for recovering it. The finely divided air need not be sterile unless it is introduced into the stream after the Wort has been partly or wholly cooled.
