Patent No. 5473161A: Method For Testing Carbonation Loss From Beverage Bottles Using IR Spectroscopy

patent-logo
Today in 1995, US Patent 5473161 A was issued, an invention of John A. Nix, Stephen W. Zagarola, and Louis Jolie, for their “Method for Testing Carbonation Loss from Beverage Bottles using IR Spectroscopy.” Here’s the Abstract:

A method for measuring carbonation loss in beverage bottles and predicting shelf-life thereof utilizes infrared (IR) absorption spectroscopy. The concentration of CO2 gas in a bottle being tested is measured with an infrared beam according to Beer’s Law. In one embodiment the CO2 gas measured is in the headspace of a test bottle partially filled with carbonated water. The walls of the bottle are clamped in a fixture to maintain the bottle diameter substantially constant. An IR beam is transmitted through the bottle just below the fixture, and absorption values of the beam are measured. Shelf-life is calculated from the absorption values. In another embodiment the test bottle is filled with compressed CO2 gas generated by dry ice placed in the bottle.

Patent No. 775780A: Art Of Brewing

patent-logo
Today in 1904, US Patent 775780 A was issued, an invention of Joseph Schneible, for his “Art Of Brewing.” There’s no Abstract, although in the description it includes these claims:

This invention relates particularly to the preparation of beer-wort, and has for its object to make-it possible to produce with certainty a wort of definite character, with reference particularly to the relationship between sugar and non-sugar, maltodextrins and dextrin, etc.

According to the methods of brewing now practiced the production of a wort of a definite or the best character in so far as it is dependent upon the relative amounts present in it of the different starch derivatives is practically impossible. This is largely due to the fact that the malt mash is subjected for a time long enough to permit conversion of the starch to take place to varying temperatures without so controlling the temperatures as to obtain the different starch derivatives in the desired proportions. This variation of temperature necessarily results from delivering, as is the customary practice, the cooked unmalted cereal mash or other heating medium,”such as hot water, which in some systems of brewing is used to raise the temperature of the malt mash, at substantially the boiling temperature to the mash-tub, which already contains the peptonized malt mash, which is at a temperature much below the boiling-point. The stream of boiling-hot cooked mash raises the temperature of the adjacent portions of the malt mash to a heat approximating its own temperature,which unduly elevated temperature continues long enough for conversion of the starch obviously where the hot cereal to begin. mash or other heating medium is thus introduced into the malt mash it is not only impossible to regulate the temperature to which portions of the malt mash are thus raised, but it is also impossible to regulate the quantity of the malt mash which has its temperature thus unduly raised, and the degree and extent Serial No. 186,592. (No specimens) of conversion or saccharification is therefore impossible of regulation under such methods.

According to the present invention the temperature of the peptonized malt mash is raised to the proper converting degree by the heat of the cooked unmalted cereal mash or other heating medium; but the attainment of the desired temperature .,is effected in so short a space of time that no reaction at other temperatures will take place, the contact of the malt mash at the peptonizing temperature with the substantially boiling hot cooked mash or other heating medium being only momentary, or rather the thorough mixture of the two being so quickly effected that no undesired reaction takes place. The contact or mingling of the malt mash and cooked mash or other heating medium preferably takes place as the two mashes or the malt mash and heating medium are moving on together in a comparatively small stream, and no portion of the malt mash remains in contact for any appreciable length of time with the cooked mash or other heating medium while the latter is at boiling temperature. In other words, the malt mash is raised to the desired converting temperature without subjecting the malt mash to reaction at any temperature other than that which is predetermined.

It will be obvious that the invention can be practiced in different ways and with different forms of apparatus, the most convenient and practicable mode of practicing the invention being to thoroughly mingle the malt mash and the hot cooked mash or other heating medium while in movement from the respective tanks or sources of supply tothe common mash-tub or strainer-tub, so that the desired converting temperature is attained at once in the commingled mashes or commingled malt mash and heating medium. After being so mingled the combined liquor is allowed to stand for the usual period of time required for conversion.

Patent Nos. 805305A & 805306A: Air Filter

patent-logo
Today in 1905, both US Patent 805305 A and US Patent 805306 A were issued, and both are related inventions of Albert Lieber, under the same name: “Air Filter.” There’s no Abstract, although in the description it includes these claims for the first one:

The object of this invention is to provide an improved construction of air-filter for filtering compressed air and removing from it impurities as well as chemically treating it during its passage through the filter.

The use to which I. have put this filter is for pitching the interior of beer-kegs and the like for blowing and spreading the warm pitch upon the internal surface of a keg by compressed air passing through this filter. In such case the bacteria and germs in the air will be embedded in the pitch and thus affect the beer, impairing its preserving qualities as well as its taste. It is therefore found very important by me that the compressed air used for the purpose mentioned be rendered chemically pure by passing the air through medicated cotton, thus arresting the particles of dust, microbes, germs, and the like. Beer-kegs treated in this way can be used immediately after being pitched and after prior use without the necessity of treating the kegs as heretofore.

US805305-0

And here’s a description of the claims for the second patent:

The chief feature of this invention consists of means for compressing the cotton or filtering material to the degree best suited for the chemical through which the air passed through the device is being treated.

The purpose of the invention, therefore, is to more thoroughly arrest the bacteria and germs of the air in the filter before the same passes through the filter. I have used it for pitching the interior of beer-kegs, the air being passed through the filter and compressed for blowing and spreading warm pitch upon the internal surface of the keg. This device prevents the bacteria and germs from the air entering the pitch.

Patent No. EP1100865B1: Process And Apparatus For Obtaining Lupulin Products From Hops

patent-logo
Today in 2003, US Patent EP 1100865 B1 was issued, an invention of Francis Lloyd Rigby, for his “Process and Apparatus for Obtaining Lupulin Products from Hops.” Here’s the Abstract:

A process and apparatus for the physical separation of lupulin from hops is provided. The process releases the lupulin glands by drying, freezing, and shaking, under specific and controlled conditions. For separating the lupulin from the hop cones a separator is provided that includes a substantially cylindrical and concentrically mounted coarse screen and fine screen. A raw hops product is received into the coarse screen that allows the coarse lupulin fraction to pass through while the coarse waste in retained within. The fine screen has a larger diameter than the enclosed coarse screen. A coarse lupulin fraction is received into the fine screen allowing the lupulin product to pass through the fine screen while the fine waste is retained within the fine screen to be discharged out the end of the fine screen. An agitator is mounted to a shaft within the separator and is utilized to beat the raw hop product. The separation process provides high yield of lupulin without sacrificing purity of product as compared to other physical separation processes. Additionally, the yield and purity of the process of the present invention compares closely to the yield and purity achieved by conventional chemical extraction methods. A superior natural hop material is thereby produced as compared to extracts, pelletized hops or baled raw hops. Lupulin can be substituted for hop extracts produced by conventional methods providing a substantial price advantage.

Patent No. 2487911A: Cluster Cutter

patent-logo
Today in 1949, US Patent 2487911 A was issued, an invention of Charles E. Wehn, for his “Cluster Cutter.” There’s no Abstract, although in the description it includes these claims:

The object of the present invention is to provide a machine whereby clusters of several hops may be quickly and readily separated. A gentle method would be to hold a cluster in the hand and with scissors clip the stems, so that leaves and hops would be separated. To circumvent such a tedious process, the present invention operates in a similar gentle manner. A hook on a revolving disc engages the stem of a cluster. As the hook raises the cluster, the hops settle to either” side of the disc and only the stem on the hook passes through the cutters, the hops falling away uninjured.
