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
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
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.
