Patent No. 3977953A: Process For The Production Of Hulupones

By

patent-logo
Today in 1897, US Patent 3977953 A was issued, an invention of Hubert Frhr. Von Hirsch and Alfons Hartl, assigned to the Atlantic Research Institute, for their “Process For the Production of Hulupones.” Here’s the Abstract:

Lupulones, which form a constituent of hop resins which have hitherto been separated and discarded because of their poor solubility, are converted into a hulupone-containing beer-soluble bitter-tasting product by photo-sensitized oxidation in a liquid alkaline medium. However, the oxidation, which is effected by means of oxygen or an oxygen-containing gas in the presence of one or more sensitizing dyes and under the action of visible light, is only partial; it is discontinued when the oxygen consumption resulting from the reaction exhibits a substantial decline, or when the fall in pH occurring during the reaction substantially ceases.

Patent No. WO2008101298A1: Brewing Apparatus And Method

By

patent-logo
Today in 2008, US Patent WO 2008101298 A1 was issued, an invention of Allan K. Wallace, assigned to Coopers Brewery Limited, for his “Brewing Apparatus and Method.” Here’s the Abstract:

The specification discloses brewing apparatus and a method for testing for end of fermentation of a fermenting brew. It has been determined that, once fermentation is complete, the temperature of a brew (such as beer) shows a tendency to stratify in horizontal layers. However, the activity of fermentation disrupts the tendency of the brew to stratify. Accordingly, the brewing apparatus comprises at least two temperature sensors positioned to measure a temperature difference between the temperature at a first height of the brew and the temperature at a second height of the brew. End of fermentation is identified if the temperature difference is greater than a threshold difference.

Patent No. 864560A: Keg Sprinkling Machine

By

patent-logo
Today in 1907, US Patent 864560 A was issued, an invention of Otto L. R. Ritter, for his “Keg Sprinkling Machine.” There’s no Abstract, although in the description it includes these claims:

This invention relates to sprinkling machines for sprinkling kegs, barrels, bottles, jars and analogous articles.

The invention primarily contemplates a machine provided with a rotatable and disappearing nozzle for applying the cleansing medium, the latter actuating the nozzle when supplied to wash or rinse an article gravity when the cleansing medium supply is cut off, thereby permitting the article to be readily removed after it has been washed or rinsed without in the least damaging the nozzle.

The invention further contemplates a machine provided with a support for the article to be washed or rinsed, said support being capable of rotation upon a vertical axis, and provided-with means for opening a hot or cold cleansing medium supply. The nozzle by its rotation projects the cleansing medium outwardly in all directions, and it is thus rendered more effective in treating a greater surface area of the article cleansed. The movement of the nozzle is rendered easy and Without obstruction when rotated by providing a ball bearing therefor, all of which will be more fully hereinafter set forth.

Patent No. 2253940A: Brew Cooling Equipment

By

patent-logo
Today in 1941, US Patent 2253940 A was issued, an invention of Gerald D. Peet, for his “Brew Cooling Equipment.” There’s no Abstract, although in the description it includes these claims:

The present invention is concerned with the art of cooling brew within the original shipping and storage package, by the circulation of cooling fluid through hollow structures in heat conductive relation with the brew contents.

As conducive to a clear understanding of the invention, it is noted that in the practical operation of brew cooling and dispensing systems of a it would be sufficient, however, to keep the contents of the kegs on reserve at ‘a temperature well above dispensing temperature and yet sufficiently cool to prevent deterioration. An arrangement which would impart such lesser degree of refrigeration to the contents of the kegs on reserve would bring about economy in power consumption and in the capacity of the refrigerating installation when it is attempted to direct the cooling fluid through cooling passages of constant area, the desired economy is not readily attainable because it is the magnitude of the cooling conduit area submerged in the brew which primarily determines the temperature to which the brew is cooled, assuming that an adequate supply of refrigeration is available, as it is in practice.

Viewed from the aspect of the keg structure per se, rather than as a system and method of operation, it is noted that the cooling instrumentalities which engage the contents of brew kegs of the internally cooled type require periodic inspection to assure their operative and sanitary condition.

For convenience and economy, it is therefore an important object so to construct and arrange such coolers as to facilitate removal thereof from the keg structures for such inspection and for repair and re-installation or replacement as the case may be, and that without bling or breaking down the kegs.
