Patent No. PP21289P3: Hop Plant Named ‘HBC 394’ (a.k.a. Citra)

By

patent-logo
Today in 2010, US Patent PP21289 P3 was issued, an invention of Eugene G. Probasco and Jason Perrault, assigned to the Hop Breeding Company, L.L.C., for their “Hop Plant Named ‘HBC 394.’” Here’s the Abstract:

A new hop plant named ‘HBC 394’ is disclosed. The cones of ‘HBC 394’ mature in early September, and yield a crop of 1200 to 1600 pounds per acre. ‘HBC 394’ is used in brewing for its bittering and aromatic properties.

You undoubtedly know this hop by its more familiar trade name: Citra. But is as so often the case with new hops, when it was first patented, it had not yet been named. Brian Yeager has a nice write-up of that process, mentioning Citra specifically, from 2011 in All About Beer magazine, entitled Hop Forward, Breeding tomorrow’s hops… today.

patent-logo
Today in 1882, US Patent 264185 A was issued, an invention of James Miller of Oakland, California, for his “Refrigerator.” There’s no Abstract, although in the description it includes this summary:

My invention relates to the class of refrigerators; and it consists generally in the construction and arrangement of peculiar vessels, providing for the holding of the substance to be kept cool, and a surrounding and underlying water-space.

It consists particularly in a deep vessel with vertical sides, and provided with a centrally perforated false bottom, upon which a holding-vessel of smaller diameter and extending above the exterior vessel is placed, whereby a surrounding and underlying water-space is formed.

It further consists in the provision of an airtight cover for the holding-vessel, all of which will hereinafter fully appear.

The object of my invention is to provide a simple, economical, and effective refrigerating device for containing any substance or article which should be kept cool.

I can’t say for certain if this was even used by breweries, but the shape seems to suggest that it may have been.

Patent No. 5553327A: Hat Made From Cardboard Beer Container

By

patent-logo
Today in 1996, US Patent 5553327 A was issued, an invention of Anthony R. Koecher and Kevin M. Schoeller, for their “Hat Made from Cardboard Beverage Container and Method of Making the Same.” Here’s the Abstract:

A hat is constructed from a cardboard product container, for example a 24-pack beer package including a product logo and other graphics thereon. The hat provides a new use for a previously wasted container material, and enables fans or collectors to display their loyalty and support of a particular brand.

This is certainly an odd one to have been patented. I’ve definitely seen hats made from 12-pack containers or similar packages, but I don’t think I knew the process was one that could be, or had been, patented.

Patent No. 3834429A: Method And Apparatus For Detecting Beverage Bottles Having A Lip Damaged Outwardly Of The Crown Sealing Surface

By

patent-logo
Today in 1974, US Patent 3834429 A was issued, an invention of Arthur F. Schulz, assigned to the Schlitz Brewing Co., for his “Method and Apparatus for Detecting Beverage Bottles Having a Lip Damaged Outwardly of the Crown Sealing Surface.” Here’s the Abstract:

Method and apparatus are disclosed for the detection of beverage bottles having a lip damaged outwardly of the crown sealing surface. Such detection is provided for in conjunction with the bottle filling operation wherein the filling apparatus seals on the bottle lip outwardly of the crown sealing surface and the bottle is then subjected to a counter pressure. If the counter pressure developed in the bottle is less than the pressure imposed on the beverage in the source reservoir, a short fill results. Thus, if the bottle lip is damaged outwardly of the crown sealing surface and in the region of sealing, a lesser counter pressure is developed in the bottle due to leakage past the seal which will result in a detectable short fill and can be rejected from the production line.

Patent No. 2806217A: Apparatus For Clarifying Brewer’s Wort

By

patent-logo
Today in 1957, US Patent 2806217 A was issued, an invention of Friedrich Schmatz, for his “Apparatus For Clarifying Brewer’s Wort.” There’s no Abstract, although in the description it includes this summary:

This invention relates to an apparatus for clarifying brewers wort.

Especially this invention refers to a process for clarifying the wort discharged from a straining vat by means of drain pipes communicating with a standpipe, drain taps being provided in the drain pipes substantially under the straining vat.

It is an object of the invention to eliminate this disadvantage so that the wort will remain substantially clear after changing the taps from the clarifying trough to the drain pipes.

According to the invention the above is brought about in such a way that at the beginning of the draining of clear wort first a communication with a small clear opening is established between the clarifying vat at the communicating system until clear water runs in the drain pipes and the standpipe is displaced by the wort, and only then the clear opening is enlarged to the full clear opening of the drain pipes.

This process may be carried out in such a way that the clarifying tap is not completely adjusted to the drain pipe when adjusting its passage from the clarifying trough to the drain pipe, so that the clear opening of the passage is reduced in this way. In this operation, however, it is difficult to reduce the clear opening to the necessary degree, that is, the opening will be adjusted too small or too wide. If the clear opening is adjusted too wide, the purpose of the process according to the invention will not be attained, and the Wort will become turbid. If the clear opening is adjusted too small, the clear water will be displaced too slowly. Several drain pipes each provided with a tap being usually provided, the clear opening of the passage cannot uniformly be adjusted at will even with the greatest care. If some taps are opened too much and others too little, an undesired turbidness of the wort will occur.
