By

patent-logo
Today in 1965, US Patent 3219319 A was issued, an invention of Michael Edward Ash, assigned to Guinness Son & Co. Ltd., for his “Concentration Control Apparatus for a Continuous Flow System.” There’s no Abstract, although in the description it includes this summary:

This invention relates in general to continuous flow systems of the kind in which liquid suspensions comprising a mechanical dispersion of sedimentable particles in a liquid of relatively lower specific gravity, are caused to flow through a processing vessel or series of vessels.

Patent No. 20120297512P1: Hop Plant Named ‘HBC 369’ a.k.a. Mosaic

By

patent-logo
Today in 2012, US Patent 20120297512 P1 was issued, an invention of Eugene G. Probasco and Jason Perrault, assigned to the Hop Breeding Company, L.L.C., for his “Hop Plant Named ‘HBC 369.'” Here’s the Abstract:

A new hop plant named ‘HBC 369’ is disclosed. The cones of ‘HBC 369’ mature in mid September, and yield a crop of 1600 to 2000 pounds per acre. ‘HBC 369’ is used for its unique aromatic quality, resistance to powdery mildew, high alpha acid content and exceptional yield.

If you don’t recognize that number, they quickly gave 369 a name, and it’s one you probably will know: Mosaic. The Hop Breeding Company has more info about Mosaic at their website, and co-inventor Gene Probasco gave a presentation at an MBAA meeting in 2012. This how Yakima Chief describes it. “Mosaic™ Brand HBC 369 cv is a daughter of the YCR 14 cv hop variety and a Nugget derived male. It has high alpha acids and tropical, blueberry, tangerine, floral, and earthy aromas.” And you can see it’s listing at HopUnion, and although the two merged to become YCH Hops, their hop varieties page is blank. It’s become a fairly popular hop variety in a very short time.

Patent No. 3353724A: Beer Tapping Device

By

patent-logo
Today in 1967, US Patent 3353724 A was issued, an invention of Mack S. Johnston, for his “Beer Tapping Device.” There’s no Abstract, although in the description it includes this summary:

Disclosed is a tapping device for beer kegs and the like and, more particularly, a probe adapter for installation in a beer keg opening. The adapter is provided with a liquid valve opened when a probe is inserted into the adapter. Also forming a part of the adapter is a positive acting gas valve which has a closure member moved by the probe to permit gas to flow into the keg through the adapter. The gas flow path through the adapter is at all times separated from the liquid flow path.

The present invention relates to a new and improved tapping device for drawing fluid such as beer from containers such as beer kegs or barrels, using a gas to drive the fluid from the container, said tapping device including a sub-unit called a keg adapter which is sealingly installed in the keg and a second sub-unit called a coupler which is attached to the beer dispensing apparatus in a restaurant, tavern or the like and is readily connectible to the keg adapter so that the tapping device is automatically set up in operating condition. More specifically, this invention relates to a new, improved keg adapter which is usable with conventional beer kegs having a. standard three-fourths inch diameter beer removal opening therein and which includes a valve means formed therein that positively prevents gas and/or beer from passing either into or out of the keg whenever the coupler is not assembled with the keg adapter, and in which gas check valve means in addition to the liquid valve means are enclosed completely within the keg adapter body.

Patent No. 2530594A: Separating Solid Matter From Hot Wort

By

patent-logo
Today in 1950, US Patent 2530594 A was issued, an invention of Fremont W. Benedict, for his “Separating Solid Matter From Hot Wort.” There’s no Abstract, although in the description it includes this summary:

The present, invention aims to effect air separation from the hot wort of most of the nitrogenous substances, and hop resins prior to the delivery of the wort to the coolers and starters. The method of the invention involves introducing the hot wortl into a charging zone where the wort is under some turbulence and from whence it flows into an adjacent and substantially larger quiescent zone. The communication between the two zones is well below the liquid level; and substantially clear wort is withdrawn from the quiescent zone near the liquid level and at a point as remote as practical from the charging zone. The apparatus of the invention comprises a tank of any desired configuration having a partition dividing the tank into a charging or feeding compartment and a’ settling compartment of considerably larger volume than the charging compartment. The lower end of the partition is spaced a short distance above the bottom of the tank, and the space between the partition and the tank bottom provides the communication between the two compartments. The hot wort is preferably delivered in a stream above the. liquid level, so that it splashes into the wort in the charging compartment and keeps the wort there in agitation. A float-controlled discharge is provided for withdrawing substantially clear wort from near the liquid level “of the-settling compartment at a point remote from the partition.

Patent No. 804979A: Brewing Apparatus

By

patent-logo
Today in 1905, US Patent 804979 A was issued, an invention of Carl Rach, for his “Brewing Apparatus.” There’s no Abstract, although in the description it includes this summary:

My present invention has reference more particularly to the construction of that part of brewing apparatus which has to do with the mashing portion of the process.

The object of my invention is to so construct the apparatus as to facilitate the mashing, the heating of the mash, its transfer from one vessel to another, and the separating of the thick mash from the thin mash, or, as it is commonly termed, lauter mash.

Patent No. 4483881A: Process For Discontinuous Wort Boiling During Beer Manufacture

By

patent-logo
Today in 1984, US Patent 4483881 A was issued, an invention of Bernhard Lenz, for his “Process For Discontinuous Wort Boiling During Beer Manufacture.” Here’s the Abstract:

In discontinuous wort boiling for the manufacture of beer, the energy of the vapor arising from the boiling is used in a heat exchanger for the production of hot water. The heated brewing water is reheated in a second heat exchange process by the energy from the vapor arising from the boiling and, with this reheated brewing water, the refined wort is heated again in another heat exchange process before the boiling, whereby the brewing water which is cooled in this heat exchange process is reheated by the energy from the vapor arising from the boiling. Thus, the energy from the vapor produced during the wort boiling is fed directly back into the wort boiling process.

Patent No. 1981014A: Beer Cooler

By

patent-logo
Today in 1934, US Patent 1981014 A was issued, an invention of Otto Weigelt, for his “Beer Cooler.” There’s no Abstract, although in the description it includes this summary:

This invention relates to beer coolers, and more particularly to the water pipe beer cooler of the type adapted for use in brewing establishments.

An object of the present invention is to provide a novel beer cooler having means for greatly improved distribution of the beer while undergoing the cooling process, so as to invoke and utilize the greatest amount of cooling efficiency of the apparatus.

A further object is to provide a beer cooler of the water pipe type having an efficient and simple means for accommodating a variation in length of the pipes employed caused by their expansion or contraction during use.

Another object is to provide end manifolds for the pipes having longitudinally slideable mountings permanently secured but capable of limited movement to accommodate variations in expansion and contraction of the water pipes.
