Patent No. 3454018A: Apparatus For Processing Beer Kegs

By

patent-logo
Today in 1969, US Patent 3454018 A was issued, an invention of Maurice Ruddick, for his “Apparatus For Processing Beer Kegs.” There’s no Abstract, although in the description it includes this summary:

Apparatus for automatically washing beer kegs or like containers comprises a head which is applied to the bung hole or other opening of the container with the container inverted, pipes connected to the head for the supply of washing water and detergent for washing the container and steam for lblowing the water and detergent out of the container after washing and a drainage pipe through which the discharged water and subsequently the steam ows from the container. The supply of water, detergent and steam is controlled by pneumatically operated valves in the pipes and the supply of air to control these valves is controlled by solenoid valves operated by an electrical sequence controller. The drainage pipe has an electrical temperature sensitive device electrically connected to the sequence controller which prevents the sequence controller from operating said Valves to cause further washing water or detergent to be supplied tothe container until all previous liquid has been blown out by the steam and there is a flow of steam through the drainage pipe over the temperature sensitive device.

Patent No. 3454199A: Keg Tapping Structure

By

patent-logo
Today in 1969, US Patent 3454199 A was issued, an invention of Dell M. Malick, for his “Keg Tapping Structure.” There’s no Abstract, although in the description it includes this summary:

A complete tapping structure is disclosed. This tapping structure consists of a keg unit or keg valve and a tapping unit which is adapted to be coupled to the keg unit so that the contents of the keg may be exhausted. The keg unit is adapted to be held upon a conventional keg neck structure by cam means so as to be secured against undesired rotation by ratchet means. The tavern unit is adapted to be coupled to the keg unit by being located upon it and twisted. The tavern unit may be removed from the keg unit by being twisted without causing the keg unit to be uncoupled from the keg neck.

By

patent-logo
Today in 1999, US Patent EP 0668347 B1 was issued, an invention of Martin Widhopf, assigned to Anton Steinecker Entwicklungs GmbH, for his “Pan For Boiling Wort During Beer Production.” There’s no Abstract, although in the description it includes this summary:

A wort kettle for boiling wort for brewing, comprising a vapor escape pipe and a vapor compressor, wherein vapor can escape to the outside via said vapor escape pipe during heating of said wort kettle and can be diverted by means of a shut-off device via said vapor compressor during boiling, characterized in that said shut-off device is formed by a surge tank which is arranged in the flow direction of said vapor in said vapor escape pipe after a branch towards said vapor compressor.


Patent No. 4277505A: Process For The Malting Of Grain

By

patent-logo
Today in 1981, US Patent 4277505 A was issued, an invention of Simon B. Simpson, for his “Process for the Malting of Grain.” Here’s the Abstract:

Germination of cereal grain in malting is carried out by passing steeped grain to and through a series of six closed spaced discrete vessels in succession. The grain is maintained in each vessel for about a day and in each vessel is subjected to an upward flow of humidified at temperated air. The grain is turned either in a vessel or through transference to the next vessel. Transference from one vessel to the other is carried out by discharging the grain from each vessel along a lower conveyor to an elevator which raises the grain to an upper conveyor that discharges the grain down into the next vessel. Grain leaves the last vessel of the series as green malt and then passes to a malt kiln where it is dried to a desired moisture level.

Patent No. 2893870A: Hopping Of Beer

By

patent-logo
Today in 1959, US Patent 2893870 A was issued, an invention of Kurt Ritter, for his “Hopping of Beer.” There’s no Abstract, although in the description it includes this summary:

The invention relates to improvements in beer brewing and more particularly to an improved method of hopping beer.

The brewing of beer comprises generally the following steps: Ground malt is mashed with water, and the obtained malt solution (first wort) is freed from the malt residues (spent grains). Subsequently, the wort is boiled with addition of the required amount of hops and then separated from the spent hops and fermented with yeast. The hops are generally added as such or in coarsely disintegrated state to the Wort.

Said procedure has the drawback that, on boiling, only about one-third to one-fourth of the bitter principle (resins), contained in the hops, passes into the wort; in addition, a certain amount of the resins, e.g. about 3 to 7 percent, is lost in further processing (fermentation and storage) by precipitation.

So far, attempts to eliminate said drawbacks have not met with satisfactory results. Recently, it has been proposed to extract the resins by subjecting the hops in water or aqueous solutions to ultrasonic irradiation and to introduce the thus obtained resin extract into the boiling wort instead of hopping with natural hops. Said method, however, must be carried out with expensive and delicate devices, the operation of which requires high energy cost, and which are therefore uneconomical for commercial purposes. The preparation of such resin extracts by means of ultrasonic irradiation takes considerable time, for instance 1 to 2 hours and more. During this prolonged treatment, undesired side reactions may take place which may affect the brewing process, for instance with respect to the uniformly fine and pleasant taste of the produced beer.

It is a principal object of the invention to provide a simple, reliable, and economic hopping procedure.

It is another object of the invention to provide a method by which the required amount of hops is considerably reduced and nonetheless a beer of uniform excellent quality and taste is produced.

Patent No. 733284A: Process Of Converting Wort Into Beer

By

patent-logo
Today in 1903, US Patent 733284 A was issued, an invention of Otto Selg and Carl Guntrum, for their “Process of Converting Wort into Beer.” There’s no Abstract, although in the description it includes this summary:

This invention relates to an improved continuous process of converting wort into beer or other fermented liquid in a single apparatus and in such a manner that the beer is first thoroughly fermented and clarified before being impregnated with the carbonic acid gas. In this way the process is accelerated and a better product is obtained.

By

patent-logo
Today in 1971, both US Patent 3591057 A and US Patent 3591058 A was issued, both inventions of Mack S. Johnston, assigned to the Republic Corp., for his “Tapping Device For Beer Kegs and the Like.” There’s no Abstract, although in the description for the first one it includes this summary:

The present device comprises a keg tapping unit which is connected about a Peerless type keg opening by insertion through the side filling opening of the keg.

Similarly, for the second patent there’s also no Abstract, although in the description for it includes this summary:

The present invention relates to a new, improved tapping device for drawing fluid such as beer from containers such as beer kegs or barrels, using a gas to drive the fluid from the container. In particular, the invention relates to a new, improved tapping device usable with conventional beer kegs and comprising a subunit, called a “keg adapter, which constantly seals the keg, and a subunit, called a coupler, which is attached to the beer dispensing apparatus in a restaurant or tavern and is readily connected to the keg adapter so that the tapping device is automatically in operating condition.

By

patent-logo
Today in 1937, US Patent 2085879 A was issued, an invention of Edward N. Trump, for his “Bottle Capping Machine.” There’s no Abstract, although in the description it includes this summary:

This invention relates to new and useful improvements in a bottle capping machine and pertains more particularly to an apparatus for applying hooded or over-all caps to the head of milk bottles or the like. The caps are pre-formed in one piece, preferably from a sheet of light, strong and non-corrosive metal having a high degree of ductility, malleability and tenacity, such for example, as tissue aluminum of about the thickness of the cellulose product commonly known as Cellophane or of thin tinfoil, and which is capable of. being easily molded by pressure under atmospheric temperature to conform to the its form under ordinary usage.
