Patent No. 2147004A: Beer Can

By

patent-logo
Today in 1939, US Patent 2147004 A was issued, an invention of Samuel Arnold Wark and Alfred C. Torem, for their “Beer Can.” There’s no Abstract, but this is just four years after the introduction of beer cans, and this is one of the more inscrutable applications I’ve read with statements like the “drawing is intended as informative rather than restrictive.” It also says simply that their “invention relates fluids under pressure are to be held, designed as a can for beer.” The rest doesn’t seem to be as informative, or well-written or even flow like many others. But it looks more like modern cans that the cans from the late 1930s.

Patent No. 6100447A: Method Of Barley Transformation

By

patent-logo
Today in 2000, US Patent 6100447 A was issued, an invention of Liying Wu and Raymond L. Rodriguez, for their “Method of Barley Transformation.” Here’s the Abstract:

A method for stably transforming barley from mature barley seeds as starting material is disclosed. The method involves germinating mature barley seeds until early shoot development occurs, exposing scutellar or embryo tissue cells on the embryo side of germinated seeds, and introducing foreign DNA into the cells. The cells are initially grown under conditions that allow expression of a selectable marker introduced with the foreign DNA, then on a callus-growth medium effective to suppress callus formation in the absence of the selectable marker. Successfully transformed calli can be cultured in suspension to obtain a desired foreign protein, or regenerated into plants, to obtain the foreign protein from the transformed plants, e.g., germinated seeds.

Patent No. 3077202A: Beer Keg Tap

By

patent-logo
Today in 1963, US Patent 3077202 A was issued, an invention of Hilbert R. Perlick, for his “Beer Keg Tap.” There’s no Abstract, but the description makes plain the aims of this patent, and what improvement it’s bring to the tapping of beer kegs:

With a view toward overcoming the danger inherent in beer keg taps heretofore available, this invention has as its purpose to provide simple means to positively assure against accidental ejection of the tap rod from the keg, by equipping the beer keg tap with a self-energizing unidirecional clutch means carried by the body thereof and operable to automatically grip the tap rod and secure it against outward movement.

Another object of this invention is to provide a beer keg tap having a self-energizing unidirectional clutch means to grip the tap rod and hold it against outward movement in which this safety feature is so designed and constructed that the attainment of the desired objective is accomplished with a minimum structural change to the existing tap and in which only one of its elements, namely the packing gland or top nut requires any modification whatsoever.

By

patent-logo
Today in 2014, just one year ago, US Patent 8646660 B2 was issued, an invention of Thomas W. Bates, Dan Morgan, and Leslie W. Ross, for their “Reusable Beer Keg.” Here’s the Abstract:

A reusable beer keg is disclosed including a hollow beer keg body with a dispenser tube assembly having a dispenser valve, dispenser tube, and a disposable bladder. The dispenser valve is releasably attached to a top portion of the keg body and the dispenser tube and bladder extend into the interior of the keg body. When beer flows through the open dispenser valve and into the bladder, the beer causes the bladder to expand until it contacts the inside surface of the keg body. When the beer keg has been emptied it can be returned to the brewery for reuse by cleaning the dispenser valve, dispenser tube and disposing of the used bladder. The beer keg parts can then be reassembled, using a new bladder in place of the used bladder.

Patent No. 2823125A: Apparatus For And Process Of Fermenting Beer

By

patent-logo
Today in 1958, US Patent 2823125 A was issued, an invention of Frank H. Schwaiger, assigned to Anheuser-Busch, for his “Apparatus for and Process of Fermenting Beer.” There’s no Abstract, but in the description it states the following:

One of the principal objects of the present invention is to provide an improved fermenter which can be fabricated from stainless steel and which requires no overhead chamber for capturing foam which must necessarily rise upwardly into said chamber. Another object is to provide an improved fermenter which requires no special housing, which is easily housed on a single floor of a building, which can be easily cleaned, which requires less space per unit capacity, and which separates the foam from the beer more completely and more efficiently. Another object is to provide a fermenter construction which moves the foam automatically toward the foam chamber. Another object is to provide a fermenter which without moving parts automatically prevents beer from spilling over a baffle into the foam chamber even though the beer increases in volume during fermentation. Another object is to provide a fermenter which can be fabricated in a metal fabricating shop, shipped to the brewery, and placed upon a suitable base therein.

Another principal object of the present invention is to provide an improved process wherein the foam condensate is directed back into the manufacturing process at a different point from where the foam was taken. Another object is to provide a process wherein the foam condensate can be filtered or treated before it is redirected into the process.

Patent No. 1086931A: Fluid-Separator

By

patent-logo
Today in 1914, US Patent 1086931 A was issued, an invention of George Anton Orth and Joshua J. White, for their “Fluid-Separator.” There’s no Abstract, but in the description it states the “object of the invention is to provide a separator, particularly adapted for use in connection with ales and beers, for separating sediment from the body of the fluid.” The description continues:

The invention embodies among other features a device provided with an inlet pipe for connection with the main barrel or the keg and an outlet pipe for connection with the tap or faucet, the mentioned pipes terminating in a container, with an end of the inlet pipe terminating in a separator cup provided with a valve operable by a float arranged within the container and movable upwardly therein as the depth of the fluid in the container increases, the float in its upward movement being adapted to close the inlet pipe to prevent the entrance of additional fluid and in its downward movement being adapted to permit the valve to open to admit more fluid to the container.

By connecting our device directly with the keg or barrel, the pressure in the device will be the same as in the keg or barrel, so that when the fluid is taken from the tap it will be as fresh as if it were taken directly from the keg.
