Patent No. 4011896A: Apparatus For Rapidly Dispensing Beer Into Open Cups

Today in 1977, US Patent 4011896 A was issued, an invention of John W. Nilon and Thomas J. King, for their “Apparatus for Rapidly Dispensing Beer into Open Cups.” Here’s the Abstract:

Beer is stored in vessels located in a refrigerated storage area before passing through dispensing lines connected to a plurality of dispensing taps. The dispensing lines are maintained in heat-exchanging relationship with cooling apparatus which further depresses the temperature of the beer below that of the refrigerated storage area. By the time the beer reaches the cooling taps, the temperature of the beer is sufficiently depressed so as to permit the beer to be dispensed at a high rate into drinking containers which pass beneath the taps.


Anchor To Release Double Liberty IPA

I generally don’t like revealing a new beer coming from a brewery before they’ve officially announced it, preferring to let the brewery manage how that information is made public. But since others have revealed it online, and because it’s pretty big news, I’m breaking my own rule. Anchor Brewery has apparently created a new beer called Double Liberty IPA.


The label has been approved, drawn by their longtime label artist Jim Stitt, although no date has yet been set for its release as far as I know right now. Since they only recently released their new Flying Cloud Stout, I suspect it will be a little while before it’s officially announced. The COLA search also reveals it will be both bottled as well as available in kegs.

According to the neck label, “Double Liberty IPA is made with 2-row pale malt and whole-cone Cascade hops.” It also apparently has “double the hops and double the IBUs.” They describe it as “imparting uniquely complex flavors and dry-hop aroma to this radically traditional IPA.” I love that phrase — “radically traditional.” It also weighs in at 8.2% a.b.v.

I’m sure we’ll learn more details soon. Anchor’s brewmaster Mark Carpenter is speaking to my class at Sonoma State on Wednesday, so hopefully he’ll be able to tell me more then. But frankly, I’m pretty excited to try this new beer. Liberty Ale has long been one of my favorite beers, and is the beer I always order first, each time I visit the brewery’s tap room. So an imperial version of that beer has to be worth trying, especially if Mark had a hand it creating it, as he did with the original Liberty 40 years ago.

Patent No. EP 0009614B1: A Brewing Process

Today in 1984, US Patent EP 0009614 B1 was issued, an invention of Kenneth Hartley Geiger, assigned to Labatt Brewing Company Ltd., for his “Brewing Process.” There’s no Abstract, but buried in the description is says that the “object of the present invention is to reduce or even eliminate the disadvantages of the above processes if the wort produced from the malt is subjected to fermentation for a period sufficient to allow the yeast to substantially develop prior to the introduction of an adjunct comprising a highly fermentable sugar and optionally, other conventional adjunct materials,” then continues with this:

This object is achieved by the present invention by initially fermenting a malt wort with brewers’ yeast until said yeast is partially developed to at least about one-half of the maximum amount of development obtainable during the fermentation, thereby providing a partially fermented wort, thereafter introducing an adjunct comprising a highly fermentable sugar into the partially fermented wort over a period of time such that the Plato value of the fermenting wort substantially does not increase and osmotic shock is avoided and then continuing the fermentation, the degree of attenuation in the brewing process being 80% or more.


Patent No. 784596A: Filling Apparatus For Liquids

Today in 1905, US Patent 784596 A was issued, an invention of Simon Schlangen, for his “Filling Apparatus for Liquids.” There’s no Abstract per se, but this is pretty close, from the introduction:

The invention relates more particularly to apparatus for filling barrels, kegs, and similar packages with liquid, such as beer, under pressure, and has for its objects to improve the suspending means by which the closing head and filling-tube are carried, so as to insure the proper contact of the closing-head with the bung-hole or filling-hole of the barrel, keg, or package, to insure the positive opening-of the valve controlling the discharge of the filling-tube when the filling-tube has reached the limit of its descent, to improve the construction and operation of the appliance carrying the closing-head and the filling tube in connection with a fluid-pressure cylinder having therein a piston by which the cross-heads carrying the closing-head and the filling-tube are raised and lowered, to utilize the waste pressure from the filling-package in actuating’ the piston by which the closing head and the filling-tube are raised and lowered, to place the control of the pressure and the liquid under a single valve, to improve the construction and operation of the valve by which the fiI’Iid-pressure and the liquid are controlled, to improve the means by which the inflow and outflow of the pressure between the filling-tank and the to be filled package is regulated and controlled, to prevent the foaming of the liquid within the package and insure the fillingI of the package with the liquid to its full capacity without waste of liquid, to furnish an intermediate controlling means for the pressure between the one controlling-valve and the to be filled package by which the flow of the pressure in either direction will be regulated and controlled, to furnish a relief-valve by means of which the requisite amount of pressure from outside will be supplied to prevent an explosion at the withdrawal of the filling-tube, and to improve generally the construction and operation of the several parts and mechanisms which enter into the “construction of the apparatus as a whole.

Patent No. 20100062104A1: Method For Filtering Beer

Today in 2010, US Patent 20100062104 A1 was issued, an invention of Ralf Schneid, assigned to Krones AG, for his “Method For Filtering Beer.” Here’s the Abstract:

A method for filtering beer, wherein the beer to be produced is guided into a filter. For the improvement of the filtering output, the beer to be produced is subjected to a shaking process before being introduced into the filter.


Patent No. 4255457A: Method And Apparatus For Preventing Buckle Of Beer Cans During Pasteurization

Today in 1981, US Patent 4255457 A was issued, an invention of George J. Collias, assigned to the Kepros-Ganes Company, for his “Method and Apparatus for Preventing Buckle of Beer Cans During Pasteurization.” Here’s the Abstract:

A method is described for preventing buckling of beer-can tops and bottoms during pasteurization of the beer. Prior to the pasteurization, an anti-buckle ring is mated with each beer can such that the ring captures the base portion of the can’s bottom. The ring permits the bottom’s panel to bulge outwardly while preventing radial displacement of the bottom’s base area and, hence, buckling of the can bottom, when the heat applied during pasteurization causes the internal pressure of the can to increase. To prevent buckle of the beer can’s top, another anti-buckle ring may be mated with the top of the can such that the latter ring captures the double-seam area on the top of the can to prevent radial displacement at key points of the top. After pasteurization, both rings are automatically removed from the can for use with another can.
