Patent No. 3227557A: Continuous Fermentation Process With Sedimentable Microorganisms

patent-logo
Today in 1966, US Patent 3227557 A was issued, an invention of Michael Edward Ash, assigned to Guinness Son & Co. Ltd., for his “Continuous Fermentation Process with Sedimentable Microorganisms.” There’s no Abstract, although in the description it includes this summary:

This invention relates in general to continuous fermentation systems of the kind in which liquid suspensions comprising a dispersion of said fermentable micro-organisms in a liquid substrate of relatively lower specific gravity, are caused to flow through a fermenting vessel or series of vessels.

More specifically, the invention is concerned with a method and apparatus for controlling the relative degree of concentration of micro-organism in substrate as between any two or all of the stages: inflow, vessel and outflow.

In particular, the invention has been developed for use in connection with the continuous fermentation of Erewers wort in a chemostat system.

The invention is however believed to be applicable to any microbiological process in which a sedimentable micro-organism is operated in a nutrient liquid, and is in the form of a mechanical dispersion in liquid nutrient of relatively lower specific gravity, so that in the absence of turbulence, the micro-organism tends to settle at the bottom of the vessel.

It has already been proposed continuously to ferment Brewers wort or other ferment-able substrate in a plurality of sequentially arranged stirred or unstirred vessels, and to separate the fermenting micro-organism (yeast) from the fermented product (beer) by settlement in a separate vessel or in a part of the final fermentation vessel separated from a stirred region by a baffle.

Beer In Ads #1768: Guinness Time


Wednesday’s holiday ad is for Guinness, from 1962. This is one of the last illustrations John Gilroy did for Guinness, and it was featured on the company magazine for Christmas 1962. The slightly angled one below is the largest image of it I could find, although the smaller one below it gives you a better look at it. I like how determined Santa is to get that glass of beer, willing to jump through a harp held my a lion.

Beer In Ads #1765: My Goodness! My Christmas Guinness!


Sunday’s ad is for Guinness, from 1952. I like the idea that Santa gets a bottle of Guinness at Christmas Eve instead of the more traditional milk for his cookies, although the addition of an evil (or at least mischievous) kinkajou seems a strange way to go. I’m not sure that Santa Claus versus the Kinkajou makes a great deal of sense, but I guess it’s a least a different approach.

Patent No. 3219319A: Concentration Control Apparatus For A Continuous Flow System

patent-logo
Today in 1965, US Patent 3219319 A was issued, an invention of Michael Edward Ash, assigned to Guinness Son & Co. Ltd., for his “Concentration Control Apparatus for a Continuous Flow System.” There’s no Abstract, although in the description it includes this summary:

This invention relates in general to continuous flow systems of the kind in which liquid suspensions comprising a mechanical dispersion of sedimentable particles in a liquid of relatively lower specific gravity, are caused to flow through a processing vessel or series of vessels.

Patent No. 3063841A: Method Of Dispensing Liquid

patent-logo
Today in 1962, US Patent 3063841 A was issued, an invention of Michael Edward Ash, assigned to Guinness Son & Co Ltd, for his “Method of Dispensing Liquid.” There’s no Abstract, although in the description it includes this summary:

I claim: l. A method of dispensing a beverage under pressure from apressurized system into a drinking vessel so as to ensure a fine, regular and enduring head on the beverage in said vessel which comprises the steps of providing in solution in said beverage a mixture of carbon dioxide and an oxygen-free inert gas and applying a counter-pressure to said beverage which acts to maintain the pressure of the mixed gases in solution in said beverage throughout the dispensing operation without substantial variation of the partial pressure of either of said gases and also acts to expel the beverage from said system through a delivery passage and tap to the outlet thereof.

Beer In Ads #1718: All This, Just To Drink A Guinness In Peace?


Saturday’s ad is for Guinness, from the 1986. On the day the United Nations was founded, I thought this ad for Guinness depicting the U.N. building in New York was appropriate. The copy is pretty funny though, referring to the beer as “fraternal Guinness” and to drink it “in peace and quiet all you have to do is become a delegate in the United Nations.” That’s because apparently Guinness is served in the dining room reserved for delegates on the top floor of the U.N. building, complete with panoramic views of the city. But I suspect there are probably easier ways to get a beer, though maybe the one we can buy aren’t “cool, fraternal Guinness.”

Beer In Ads #1664: Daisy, Daisy


Monday’s ad is another one for Guinness, this time from 1937. This is an odd little ad. A couple — who to my eyes look almost identical except for their clothing — had to stop while bicycling through the countryside. While he tried to fix the bike, she sensibly fixed lunch. Yet he seems chuffed that she’s not eager to share, even calling her lazy. Not a great date.
