Patent No. 3123476A: Production Of Hopped Wort

Today in 1964, US Patent 3123476 A was issued, an invention of Michael Edward Ash, assigned to Arthur Guinness Son and Company for his “Production of Hopped Wort.” Here’s the Abstract:

The invention relates to the hopping of wort, a stage in the brewing process which takes place prior to fermentation. The object of the hopping process is to extract from the hops and transfer to the Wort certain desirable flavouring substances particularly humulone, or substances derived therefrom, which are generally considered to provide the bitter flavour in finished beer, and which in some cases may exercise a preservative function.


Patent No. 3498313A: Beer Keg Tap

Today in 1970, US Patent 3498313 A was issued, an invention of Daniel E. Belich, for his “Beer Keg Tap.” Here’s the Abstract:

This application discloses a tap in which the portion of the tap from the head to the bottom of the keg may remain in place during merchandising. The user needs only a small coaxial outlet unit attached to tap beer and gas pressure lines. The outlet unit is small and easily cleaned, and represents only a modest investment for the tavern keeper. The portion of the device which is retained in the barrel contains valving arrangements which prevent the escape of beer or gas pressure from a partially used keg when the outlet is withdrawn, and provide improved Valve arrangements which rely on elastic valve members for admission of air under pressure.


Patent No. 2290089A2: Barley For Production Of Flavor-Stable Beverage

Today in 2011, US Patent 2290089 A2 was issued, an invention of Søren Knudsen, Lene Mølskov Bech, Klaus Breddam, Finn Lok, Ole Olsen, and Birgitte Skadhauge, assigned to Carlsberg A/S, for their “Barley for Production of Flavor-Stable Beverage.” Here’s the Abstract:

According to the invention, there is provided null-LOX-1 barley and plant products produced thereof, such as malt manufactured by using barley kernels defective in synthesis of the fatty acid-converting enzyme lipoxygenase-1. Said enzyme accounts for the principal activity related to conversion of linoleic acid into 9-hydroperoxy octadecadienoic acid, a lipoxygenase pathway metabolite, which – through further enzymatic or spontaneous reactions – may lead to the appearance of trans-2-nonenal. The invention enables brewers to produce a beer devoid of detectable trans-2-nonenal-specific off-flavors, even after prolonged storage of the beverage.


Patent No. 3171746A: Production Of Brewers’ Wort

Today in 1965, US Patent 3171746 A was issued, an invention of David Teignmouth Shore, for his “Production of Brewers’ Wort.” There’s no Abstract, but in the description Shore explains that his “invention relates to the production of brewers wort at the mashing stage in which a reaction is created between water and goods, i.e., ground solids or grist to obtain as a product of the stage a wort which is known as sweet wort: the sweet Wort is passed on for further treatment including heating, hopping and fermentation treatment to produce beer of one grade or style or another.”

Patent No. 4728010A: Keg Tapper

Today in 1988, US Patent 4728010 A was issued, an invention of Mack S. Johnston, for his “Keg Tapper.” Here’s the Abstract:

A keg tapper for use with a keg having a neck with a closure valve carried therein and a flange with a tapered edge on the neck. An arrangement for attaching the tapper at the flanged neck so that completion of the attachment opens the inner valve of the keg closure. A plunger carried in the keg tapper with an arrangement for moving the plunger axially within the tapper body to engage the keg closure and open the outer valve. A keg tapper which can be utilized in the tavern configuration and in the picnic configuration.

Patent No. 2462930A: Keg Closure

Today in 1949, US Patent 2462930 A was issued, an invention of Victor Alvear, for his “Keg Closure.” There’s no Abstract, but the description claims that the “object of the present invention to provide a bung for a keg in which the stopper is a fixture on the keg and cannot become lost and the chance of its becoming damaged is reduced to a minimum.” Alvear also writes that in addition, additional reasons for his patent include the “means for bringing the stopper or plug to alignment with the bung hole by gravity where it can easily be moved into closed position, the “means for readily grasping it with a tool and with means for sealing the opening in the bung,” “eliminate hammering and pounding on the barrel head and to eliminate spearing of corks,” to “facilitate tapping of the keg,” “provide a stopper that is sanitary, simple in construction and economical to manufacture,” “provide a stopper that cannot leak or blow out regardless of the pressure in the keg thereby providing an air-tight seal,” and “to provide a stopper that is self-sealing.” That is one impressive keg stopper.

Patent No. 2109489A: Liquid Filling Machine

Today in 1938, US Patent 2109489 A was issued, an invention of John Daniel Le Frank, assigned to the American Can Co., for his “Liquid Filling Machine.” There’s no Abstract, but the description states that the “present invention relates to a machine for filling cans with liquids that have a tendency to foam and has particular reference to devices which minimize foaming of the liquid passing into a can, passages in the devices being automatically purged of any foam which may have accumulated during the filling of a preceding can.”

Patent No. 254120A: Beer-Cooler

Today in 1882, US Patent 254120 A was issued, an invention of Patrick J. Daroy, for his “Beer-Cooler.” There’s no Abstract, but the description states that his “improvement relates to a device for cooling beer as it is drawn from the cask, by which it is cooled as it is used, instead of being obliged to cool the cask, and thereby diminish the head or pressure, besides the waste of ice in cooling through the wood.”

Patent No. 1899203A: Combined Bottle Opener And Key Ring

Today in 1933, US Patent 1899203 A was issued, an invention of Joseph Charle Auguste Labreche, for his “Combined Bottle Opener and Key Ring.” There’s no Abstract, but the simple description states that the “invention pertains to a novel combined bottle opener and key ring designed a to be carried conveniently-in the pocket.” Weird to think that this had to be patented, they seem so ubiquitous now.
