Patent No. 2477222A: Beer Dispenser With Coil Cleaning Means

By

patent-logo
Today in 1949, US Patent 2477222 A was issued, an invention of Frederick J. Warcup, for his “Beer Dispenser with Coil Cleaning Means.” There’s no Abstract, although in the description it includes this summary:

This invention relates to beer distributing systems such as are used in taverns and saloons for conducting beer from kegs, in which the beer is delivered from the brewery, to taps located behind the bar. The length of piping between a keg and the tap includes a cooling coil through which the beer flows.

One object of the invention is to provide an improved beer distributing system in which water can be conveniently introduced into the beer lines and accurately controlled so as to avoid the loss of beer that results from having beer stand in the pipes, from draining of the lines for cleaning, and the loss that occurs when an empty keg is replaced with a full one.

It is another object of this invention to provide means by which tavern operators can clean their own lines without having to connect or disconnect any unions or fittings, and in the preferred embodiment of the invention the system is constructed so that the beer lines can be cleaned without even leaving the bar. The tavern operator can fill his beer lines with water preparatory to cleaning them and all of the usual loss of beer incident to cleaning line is avoided.

Another important saving is effected by this invention when a keg becomes empty and it is necessary to tap a new keg. Whenever the contents of one keg become exhausted, the beer line fills with foam and the first beer from a new keg surges into the line and foams to such an extent that the first glasses drawn after a new keg has been tapped cannot be used because of excessive foam. With this invention the line is filled with water before tapping a new keg and there is no surge of beer into the line.

Beer In Ads #1628: The Goodness Of Malt While Boating

By


Saturday’s ad is for the Barley and Malt Institute, from 1959. This is the fifth ad I have from the now defunct trade group for barley growers. In this one a woman is pouring a beer on the dock for a man sitting in boat of uncertain size, though it’s probably relatively small, and trying to grab the glass (glass?!?) mug even before she’s finished filling it. The tagline is similar to other Malt Institute ads, suggesting it was a series of ads: “Fun-Flavors your favorite beer—healthfully.” I’m not even sure that quite makes sense.

Patent No. 3332748A: Extraction Of Hop Bitters From Beer With Iso-Octane Using Synchronized Pulses In A Helical Coil

By

patent-logo
Today in 1967, US Patent 3332748 A was issued, an invention of Jack Albert Spicer and Max William Betts, for their “Extraction of Hop Bitters from Beer With Iso-Octane Using Synchronized Pulses in a Helical Coil.” There’s no Abstract, although in the description it includes this summary:

This invention relates to the extraction of chemical substances from liquid mixtures and in particular to the extraction of such substances from complex mixtures for purposes of analysis.

In the analysis of a complex mixture, it may be desired to separate one or more constituents of the mixture, by liquid/liquid extraction methods, in order to obtain a relatively simple solution, for example for spectrographic analysis. Thus, for example, it has been proposed to extract hop bitter substances from brewers wort or beer by liquid/liquid extraction with iso-octane, whereupon the solution of the hop bitter substances may be analyzed by ultra-violet spectrographic analysis. The present invention provides an extraction process suitable for use in the separation of desired compounds from such mixtures.

According to the invention, a process for the extraction of a chemical substance from a liquid mixture comprises feeding the liquid mixture and a solvent for the desired chemical substance in synchronized pulses through a horizontally disposed coiled tube, and separating the residual liquid mixture from the solution of the desired chemical substance in the solvent. Preferably the coiled tube is helically coiled.

Patent No. 998815A: Beer-Making Apparatus

By

patent-logo
Today in 1911, US Patent 998815 A was issued, an invention of Ernst Uhlmann, for his “Beer-Making Apparatus.” There’s no Abstract, although in the description it includes this summary:

My invention relates to that portion of the beer making art wherein the wort is treated with hops, and it has for its objects to provide an apparatus for preventing the wort from acquiring an objectionable color and flavor and from a tendency to sour as a result of such treatment.

My invention is designed to overcome these objections and to provide a form of apparatus for rapidly removing the hops from the wort, which shall ‘be simple in construction and operation and require much less floor space for accommodation than apparatus commonly used for the purpose.

In carrying out my invention I remove the hops, albuminoids, and such matter from the wort while the latter is flowing from the brewing kettle to the coolers, so that the wort is freed from these matters almost immediately it leaves the brewing kettle, and does not remain in contact with the hops, etc., longer than a few seconds. Also I remove all the wort from the hops without employment of any mechanical or air pressure.

Beer In Ads #1627: Take Off On A Completely Unique Experience

By


Friday’s ad is for Colt 45 malt liquor, from 1969. I guess they were playing off the popularity of the space race in 1969, when Neil Armstrong walked on the Moon. It’s a pretty weird ad, and I’m not sure about a lot of it. Why, for example, is the man just wearing a conservative black suit? And why is he surrounded by two odd-looking alien women in space suits behind a wall of Colt 45 cans. It certainly is “out of this world,” as the cheesy ad suggests.

Patent No. 1234255A: Process Of Treating Beer

By

patent-logo
Today in 1917, US Patent 1234255 A was issued, an invention of Charles S. Ash, for his “Process of Treating Beer.” There’s no Abstract, although in the description it includes this summary:

This invention relates to a process of treating beer; and has for its object to stabilize beer by eliminating the causes of cloudiness and turbidity therein, and also to prevent the development of color and the development of a cooked taste in the beer following pasteurization.

In the brewing and finishing of beer, the aim of the brewer is to obtain a product which is brilliantly clear and transparent and which will so remain under all conditions of subsequent handling.

Beer is rendered turbid or cloudy on standing, particularly in the cold, by reason of the precipitation of nitrogenous bodies. In the process of mashing the grains and making the wort, which is subsequently fermented, a portion of the nitrogenous bodies of the grain is brought into solution. After the fermentation and the aging or lagering to which the new beer is subjected some of these nitrogenous bodies are precipitated and are removed by filtration. After the final filtration the beer is brilliant, but upon storage in the case of keg beer, and upon pasteurization and storage in the case of bottled beer, the beer gradually becomes cloudy and finally turbid.

There are two ways in which this cloudiness and turbidity can be prevented; first, by the absolute removal-of the nitrogenous bodies still held in the lagered beer, which are susceptible to subsequent precipitation through storage or heating or cooling; and, second, by treating the lagered beer in such a manner that these, nitrogenous bodies remain in solution. The first method has never been hitherto successfully accomplished. The second method has yielded results of more or less value and is accomplished by adding to the beer substances known as enzymes, which have the power of rendering these insoluble nitrogenous bodies soluble and hence the beer remains brilliant.

Beer In Ads #1626: Vårt Brygg!

By


Thursday’s ad is for Brigg beer, a brand from Norway. From the 1970s, with the simple tagline “Vårt Brygg!,” which translates as “Our Brew.” You’ve got to love the trio of serious sweater monkeys. They look like the original reporters from Anchorman that they based the movies on, especially since the dude in the ascot on the right is a dead ringer for Will Ferrell.

Patent No. 4530631A: Pull Tab For Easy Open Can End — Method Of Manufacture Thereof

By

patent-logo
Today in 1985, US Patent 4530631 A was issued, an invention of Elton G. Kaminski and Carl F. McEldowney, assigned to The Stolle Corporation, for their “Pull Tab For Easy Open Can End — Method Of Manufacture Thereof.” Here’s the Abstract:

An easy open can end having a retained tear strip extending diametrically partly across the can end defined by a score line, and a graspable pull tab adjacent and outside the open end of the score line. The pull tab is provided with a nose portion to initiate a tear along the score line upon lifting of the pull tab. The edges of the nose portion are curled into a cylindrical cross-sectional shape to provide a high beam strength and to rigidize the nose portion and to prevent failure by bending before the tear strip is opened. A method for manufacture of the pull tab includes forming at least one relief notch in the peripheral edge of the pull tab blank at the nose end thereof, whereby to relieve compressive forces when the edge is curled, and curling the peripheral edge of the nose portion in successive steps to form an edge portion of continuous cylindrical cross-sectional shape.
