Patent Nos. 2546250A & 2546251A: Process Of Concentrating Yeast Slurries & For Drying Yeast

Today in 1951, US Patents 2546250 A and 2546251 A were issued, both inventions of Stanley L. Baker, for his “Process of Concentrating Yeast Slurries” and “Process for Drying Yeast.” There’s no Abstract for either, but the description for the first is an “invention relat[ing] to the concentration of dilute suspensions or slurries of yeast and especially of brewers yeast slurry which will be referred to hereinafter as an example although it will be understood that the invention is not restricted thereto.”

His second patent is described as an “invention relat[ing] to drying dilute suspensions or slurries of yeast and especially brewers yeast slurry which will be referred to hereinafter as an example, although it is to be understood that the invention is not restricted thereto.” You may have noticed that this description is exactly the same as the first. What’s clear is while these are two different patents, they are vey similar and are both about roughly the same yeast process. Even the drawings are only slightly different from one another.

Patent No. 2740049A: Method And Apparatus For Destruction Of Live Yeast Cells In Beer

Today in 1956, US Patent 2740049 A was issued, an invention of William C. Stein Sr., for his “Method and Apparatus for Destruction of Live Yeast Cells in Beer.” There’s no Abstract, but the description states that the “invention relates to a method and apparatus for destroying live yeast cells in beer.” When he lays out the various objects for the invention, it’s clear that the yeast is destroyed when “the beer is cascaded over violet ray tubes,” allowing for the “continuous treatment of the beer.” It apparently differs from how this was accomplished beforehand, as using this method “the beer will be subjected to a pre-carbonation pasteurization whereas under prior process the beer was pasteurized after carbonization.”

Patent No. 1995626A: Manufacture Of Minim Alcohol Beverage

Today in 1935, US Patent 1995626 A was issued, an invention of Karl Schreder, for his “Manufacture of Minim Alcohol Beverage.” There’s no Abstract, as far as I can tell, Minim means low-alcohol. I wonder if that was a common term back then? It’s not one I hear these days. Curiously, although the invention relates to what they call “low alcohol beverages,” the percentage of alcohol is never discussed, which strikes me as odd. Here’s what is revealed:

It has been found that Termobacterium mobile (Lindner) (Pseudomonas Lindneri-Kluyver) discovered by Professor Dr. Lindner is particularly suitable for the manufacture of beverages containing a low proportion of alcohol.

A process for the manufacture of beverages of this kind forms the subject-matter of the present application.

For obtaining a high grade end product it is essential that the preparation of the malt and of the wort be carried out carefully.

Okay, but what is the “high grade end product?” Is it non-alcoholic or near beer below 0.5% a.b.v.? Or something that might be considered a session beer with an alcohol percentage lower than a beer of typical strength?

Patent No. 1021669A: Beer-Tapper

Today in 1912, US Patent 1021669 A was issued, an invention of William W. Frisholm, for his “Beer-Tapper.” There’s no Abstract, but the description states that his “invention is an improvement in beer tappers, and consists in certain novel constructions, and combinations of parts, hereinafter described and claimed. Sometimes the language in these is just wonderful, case in point:

The object of the invention is to provide an improved device for tapping beer and other effervescing liquids which will permit the entering of the device into the keg or other receptacle without waste, and which, while permitting the free egress of the liquid, will also permit the entrance of air under pressure to force out the liquid.


Patent No. 848228A: Cooler For Beer

Today in 1907, US Patent 848228 A was issued, an invention of Johann Ettel, for his “Cooler for Beer or Other Beverages.” There’s no Abstract, and the description is without a doubt one of the worst OCR conversions I’ve ever seen. For example, here’s what should be the introduction, verbatim:

To afl’ whom` if my Concern.- l Be it’known that I, JOHANN ETTEL, a enbject of the Em eror of AustriaHungalj, Brooklyn, county of Kings,

new and useful Improvements in (loolers for Beer or other Beverages, of Whiel’ithe following is eepeei’lieet-ion- L The`presentinvention ‘has for its object to provide n. meier for heer or other beverages principally in hors;restaurant-s, mul the like.- v

Which I think we can infer that Johan Ettel, who was from Austria-Hungary, but living in Brooklyn, invented a new beer cooler.

Patent No. 8678247B2: Creamy Foam Beer Dispensing System

Today in 2014, just one year ago, US Patent 8678247 B2 was issued, an invention of Paul Haskayne, Robert W. Shettle, Donald W. Smeller, Jarrell L. Jennings III, and Merrill R. Good, assigned to the Lancer Corporation, for their “Creamy Foam Beer Dispensing System.” Here’s the Abstract:

A creamy foam beer dispensing system includes a coupler removably securable with a keg, a transportation tube, and a faucet having a handle coupled with a plunger communicating with the transportation tube. The handle is movable among a closed position, an open position, and a creamy foam position. In the closed position, the handle maintains the plunger squeezed against the transportation tube such that no beer flows from the faucet. In the open position, the handle lifts the plunger substantially, completely off the transportation tube such that beer flows smoothly from the faucet. In the creamy foam position, the handle lifts the plunger off the transportation tube a distance such that an aperture created in the transportation tube produces creamy foam flow from the faucet.

Patent No. 3501934A: Apparatus For Repairing Kegs

Today in 1970, US Patent 3501934 A was issued, an invention of Albert W. Engel and Gerald J. Forbes, for their “Apparatus For Repairing Kegs.” There’s no Abstract, but the description states that the invention relates to a “method and apparatus for repairing metal kegs, such as the aluminum kegs used for containing beer. The apparatus includes a die shaped to the outside form of the keg. The deformed externally projecting parts of the keg are pressed into an area defining original confines of the keg. In other words all external projections are forced inwardly by pressure. To return the keg to its original condition, the keg is filled with water, and an explosive is placed in the keg. The explosive is detonated to blow the keg back to its original form. The method comprises a hydraulic means of expanding kegs against a closed die to return the kegs to their original shape.”

Patent No. 3174650A: Bung Withdrawing Assembly

Today in 1965, US Patent 3174650 A was issued, an invention of Frank A. Bellato, for his “Bung Withdrawing Assembly.” There’s no Abstract, but the description states simply that the “invention relates to a device for removing the wooden bungs from beer kegs and similar containers after such kegs have been emptied of their contents.” Then the goals of their patent application are laid out:

A major object of the invention is to provide an auger, of special form for the purpose, having a pilot portion arranged so as to first penetrate the bung along a path axially of the bung without possible deviation from such path such as grain direction or irregularities in the wood of the bung might cause, and having a portion following the pilot portion arranged to then advance into the bung in a manner to cause the bung to be withdrawn from the bung hole and split into separate sections so that such sections will fall of themselves from the auger.

It is another and important object of the invention to provide a means for operatively mounting the auger, both for rotation and axial movement, in an upwardly facing position, and a means for supporting the keg above the auger in such a position that the bung, which as usual is in one side of the keg, will be disposed in a downwardly facing position directly in line with the auger.

The importance of having the bung disposed in an inverted position, with the auger disposed below the keg and bung, is that no chips or wood dust, as created by the action of the auger, can enter the keg but will drop down clear of the keg.

A further object of the invention is to provide a catch tray and carryotf chute in connection with and directly below the auger which will receive, and cause to be carried alway, all chips, withdrawn bung pieces, as well as any liquid residue dropping from the empty keg when the bung is withdrawn, and keep such waste matter from possibly fouling the auger supporting and operating mechanism.

The keg, when initially placed on the supporting means, may not always be disposed with the bung in the necessary downwardly facing position, and a still further object of the invention is to provide a keg support-ing means which enables the keg, after once being supported, to be easily rotated so as to dispose the bung in the proper position for engagement by the auger.

In connection with this latter feature, it is also an object of the invention to provide a clamping unit for engagement with the top of the keg, which will rst exert a yieldable hold-down action on the keg which still allows the keg to be rotated if necessary, and which will then clamp the keg against any movement. At the same time, the clamping means is mounted so that it can be readily moved clear of the keg so as to offer no interference with the placement of the keg on or removal of the same from the supporting means.


Patent No. DE2145298A1: Instant Beer Powder

Today in 1973, US Patent DE 2145298 A1 was issued, an invention of Siegfried Beissner, for his “Instant Beer Powder — by vacuum-freeze drying.” Here’s the Abstract:

Beer is subjected to vacuum-freeze drying at -10 degrees to -20 degrees C, under a press. of about 0.5 atm. with agitation. Beer can be rapidly restored by treating the powder with water and a source of CO2 (pure CO2 or a mixt. of NAHCO3 and tartaric acid) and/or alcohol. The CO2-source and/or alcohol can be enclosed in capsules made from water-sol. gelatine and packed together with the beer powder.


Given that we’re seeing this type of product in the trade recently, and the anti-alcohol groups have been going apeshit, I would have thought this was a more recent invention. But a version of it was around at least as early as 1973, over forty years ago. I wonder why it took so long for it to make it to market?

Patent No. 3310407A: Fermentation Processes For The Production Of Beer

Today in 1967, US Patent 3310407 A was issued, an invention of Michael George Royston, for his “Fermentation Processes for the Production of Beer.” There’s no Abstract, and the application simply says that the “invention relates to the continuous production of beer.” It’s later summarized with this:

The invention concerns the stage at which hopped Wort including yeast, as is conventional, is allowed to ferment to produce beer as the final product. In this fermentation stage of production the rate of’conversion of the sugar in the wort is a function of the concentration of sugar and of the enzymic yeast cells in the wort.
