Patent No. 4927335A: Pump For Transferring Liquids, In Particular Beer Or Carbonated Beverages

By

patent-logo
Today in 1990, US Patent 4927335 A was issued, an invention of Carlo M. Pensa, for his “Pump For Transferring Liquids, in Particular Beer or Carbonated Beverages.” Here’s the Abstract:

The present invention relates to a pump for transferring liquids, in particular for beer or carbonated beverages, characterized in that it is constituted by two mutually opposite and integral pistons sliding inside two cylinders which generate, with their reciprocating motion, four variable-volume chambers inside two of which the fluid, through suitable valves, is alternatively intaken and delivered by a gas whose pressure is modulated by a suitable pressure regulator, in which it is the pressure of the same delivered liquid to counteract the calibration force, with said gas alternatively going to act, by means of suitable control means, inside the chamber behind the delivery chamber, so that the delivery pressure of the same liquid remains constant and predetermined, wherein said delivery pressure is obtained as the sum of the thrust of the liquid intaken from the opposite chamber, plus the modulated gas pressure, which acts on the rear face of the delivery piston.

patent-logo
Today in 1957, US Patent 2792692 A was issued, an invention of Reed A. Bryan, for his “Keg Cooler And Dispensing Bar Unit.” There’s no Abstract, though it’s described this way in the application:

The primary object of the invention is to provide a combined keg cooling enclosure simulating a large beer barrel, dispensing bar and faucet, and auxiliary pressurizing equipment in a single unit for use at picnics, beach and boat parties, club outings and the like events.

More specifically, it is intended now to provide a keg enclosure in the form of a relatively large open-top barre]. A bar-top removably fitted over the top of the barrel so that a keg may be set down within the barrel and packed with ice, and tapping and dispensing equipment including a faucet mounted on the bar-top and a carbon dioxide cylinder mounted exteriorly of the barrel with gas connections to the top. By this arrangement there is to be provided a complete unit which may be set up iced by a distributor or dealer and delivered to the consumers in readiness for tapping and utilization without further ado.

Patent No. 1951996A: Brewing Pan

By

patent-logo
Today in 1934, US Patent 1951996 A was issued, an invention of Josef Schaefer, for his “Brewing Pan.” There’s no Abstract, though it’s described this way in the application:

My invention relates to improvements in brewing pans, and more particularly in the construction of the rotary liquid heater. One of the objects of the improvements is to provide a liquid heater which is simple in construction, and in which the water of condensation is readily removed from the heating coil. With this object in view my invention consists in providing the liquid heater with a single heating pipe wound into a coil having several superposed windings, each winding being preferably substantially in the form of a star. By constructing the coil from a single pipe only two openings are needed in the supply one for admitting the steam and the other for removing the water of condensation.

By

patent-logo
Today in 1987, US Patent 4665940 A was issued, an invention of Charles S. Jacobson, for his “Container Fitting.” Here’s the Abstract:

A fitting for a container of draft beer or the like includes a first valve for permitting pressurized gas to be injected into the container and a second valve for permitting beer to be dispensed from the container. Both valves are urged to their closed positions by inexpensive elastomeric springs which also serve to hold certain components of the fitting in assembled relation. A coupler attaches the fitting to the container and enables the container to be used with Sankey-type taps.

By

patent-logo
Today in 1988, US Patent WO 1988003556 A1 was issued, an invention of Joseph L. Owades, for his “Preparation Of Wort Extracts.” Joe is most well-known for having invented low-calorie light beer. Here’s the Abstract:

A method for producing a wort containing a reduced level of fermentable sugars. In a preferred embodiment the method consists of providing a warm aqueous suspension of ground malt, and adding the warm suspension to a boiling aqueous suspension of cereal adjuncts. The resulting wort is useful for producing a beer with a lower-than-normal alcohol content, or a malt beverage lacking sweetness usually associated with malt beverages.
