By

patent-logo
Today in 1979, US Patent 4154865 A was issued, an invention of Herbert L. Grant, assigned to S. S. Steiner, Inc., for his “Method for Processing Hops for Brewing.” Here’s the Abstract:

There is provided a method of processing hops or hop extracts for brewing in which hops and particularly the alpha acids in the hops are stabilized against deterioration and light sensitivity, the process broadly comprising isomerizing a substantial portion of the alpha acids in the hops and contacting said iso-alpha acids witha metallic hydride compound, the metal thereof being suitable for use in foods, until the reaction is substantially completed. In another aspect, the alpha acids present in the hops are converted to their reduced isomerized products which are desirable for brewing. The process is especially suitable for use in pelletizing operations.

Patent No. 2001040A: Beer Dispensing Equipment

By

patent-logo
Today in 1935, US Patent 2001040 A was issued, an invention of David Sweeney, for his “Beer Dispensing Equipment.” There’s no Abstract, but it’s described as an “invention relat[ing] to beer dispensing equipment, and more particularly to equipment for handling, cooling, and dispensing, beer or other liquids.” And this appears to be the main feature.

One feature of my invention is that it is adapted for easy handling of quantities of liquid up to ten gallons or more. Another feature of my invention is the provision of means for expelling liquid, for example, beer, from a container without exposing the liquid remaining in the container to air. This is especially useful in dispensing beer where one container may be more or less infrequently used. In the ordinary case, for example, if a beer container is partially emptied, and air allowed to enter the container to fill up the space previously occupied by the liquid drawn off, the liquid remaining in the container is likely to become spoiled by contact with the air, especially if not used rather promptly. All these objections are overcome by my inventions I apply an inert gas, for example, carbon dioxide gas, (or some gas which will not spoil the beer or other liquid in the container) to the top of the container under suitable pressure. This gas then serves not only to expel the liquid from the container as it is used, but also fills up the space in the container occupied by the liquid drawn off, so that no spoilage results to the liquid remaining in the container. Still another feature of my invention is the elimination of cooling coils with their tendency to spoil beer standing in them.

Patent No. 3443958A: Method Of Preparing Ground Cereal Grains In The Production Of Brewery Mash

By

patent-logo
Today in 1969, US Patent 3443958 A was issued, an invention of George E. Dennis, Richard C. Quittenton, and Kenneth R. Robinson, assigned to John Labatt Ltd., for their “Method of Preparing Ground Cereal Grains in the Production of Brewery Mash.” There’s no Abstract, but the invention is described as a “process for producing brewers wort in which cereal grains are dehulled, the dehulled grain is ground to form a fine grist and at least part of the hulls removed before grinding are recombined with the ground dehulled grain and passed through the mashing stage in the usual manner.” Here’s why they think their method is better.

According to this invention it has been determined that the above difficulties [milling problems] can be overcome by removing the hull from the grain before the milling operation. With the hulls removed the kernels of grain can now be more finely ground than was possible in the past and then the finely ground kernels can be recombined with the hulls at any point before the lautering stage. The result of this is an increased yield without any significant sacrifice in run-off time. A series of pilot plant tests indicated that an average yield increase of up to 2% could be obtained with a less than a 15% increase in lautering time.

The degree to which the kernels can be more finely ground according to this invention will be entirely dependent upon the particular situation. Thus, the actual particle size will be dependent upon the nature of the grain, the balance of the lautering time against yield permissible in a given situation, etc.

By

patent-logo
Today in 1909, US Patent 921032 A was issued, an invention of Ralph Waldo Webster and Leuig Chew, for their “Counter-Pressure Bottling-Machine for Beer, Mineral Waters, and the Like.” There’s no Abstract, and all it says in the description is that Schwartz “invented new and useful Improvements in Counter-Pressure Bottling-Machines for Beer, Mineral Waters, and the Like,” which is essentially the title. A bit more is subsequently added, saying the “invention relates to improvements in machines for filling bottles, jars, and other like vessels, in which a counter-pressure is created to enable beers, mineral waters, and the like, having a natural or artificial condition or pressure, to be bottled Without undue foaming or loss of condition.” For the rest, you have to dive into a full reading of the application.
