Patent No. 4212950A: Fermenting Apparatus

By

patent-logo
Today in 1980, US Patent 4212950 A was issued, an invention of Robert P. Adams, assigned to The Virtis Company, Inc., for his “Fermenting Apparatus.” Here’s the Abstract:

Apparatus providing for the growth of cells in a nutrient bath under controlled conditions includes a pressure vessel with a surrounding dimpled jacket. The pressure vessel is adjustably mounted on three vertical mounting columns, from which it is thermally isolated. Temperature control for the pressure vessel is achieved by a closed heat transfer system which includes a pair of heat exchanger sections in series, one for heating and one for cooling the heat transfer fluid. A removable head or lid for the pressure vessel is lifted by three cables running through a common pulley mounted above the pressure vessel. Impeller blades for agitating the contents of the fermenting apparatus have a drive shaft that extends through the head and is connected to a gear box by a removable driving link. The gear box, and an associated drive motor, are affixed to a common mounting bracket that is pivotable to permit maximum displacement of the head.

Patent No. 2894844A: Canning Process And Product

By

patent-logo
Today in 1959, US Patent 2894844 A was issued, an invention of James G. Shakman, assigned to the Pabst Brewing Co., for his “Canning Process and Product.” There’s no Abstract, although in the description it includes this summary:

[This invention is for an] improved process for canning substances which are processed during the general course of canning and which contain a gas, or contain vaporizable liquid, or are capable of expanding and so are capable of producing internal pressure in the can during such processing.

A more specific object of the invention is to provide a new and improved process for canning carbonated liquids, such as beer and other carbonated beverages, which are normally canned with a head space above the liquid level.

Today in 1909, US Patent 927893 A was issued, an invention of John R. Steiger, for his “Beer-Pipe-Cleaning Apparatus.” There’s no Abstract, although in the description it includes this summary:

My invention relates to a new and useful beer pipe cleaning apparatus and consists in providing means whereby a circulation of the cleansing material may be made through the pipes. It further consists of means for directing the flow of the cleansing material first in one direction and then in the other through the pipes. It further consists in providing an ejector for forcibly directing water and air through the pipes.

Patent No. 2324312A: Bottle Feeding Mechanism

By

patent-logo
Today in 1943, US Patent 2324312 A was issued, an invention of George J. Meyer Jr., Charles Steckling, and Joseph F. Classen, for their “Bottle Feeding Mechanism.” There’s no Abstract, although in the description it includes this summary:

The present invention relates to feeding mechanism adapted for use in connection with bottle handllng machines, such as cappers, fillers and labelers, although the invention is also applicable to the feeding of cans and other articles.

A bottle-handling machine, such as a capper, is commonly provided with a traveling carrier having means for holding the upstanding bottles in spaced relation to present the bottles successively to the operation of the machine. It is also common practice to provide the machine with a conveyer for conducting the bottles to the carrier, the successive bottles on the conveyer being usually in abutting or closely spaced relation. The spacing of the bottles on the carrier is ordinarily somewhat greater than the bottle diameter and because of this and other factors it is necessary to provide some means for controlling the feed of the bottles to the carrier, so as to suit the bottle spacing or bottle pitch of the carrier. Various mechanisms have heretofore been devised for this purpose, but they have been open to certain objections, such as relatively complicated construction and excessive rubbing and agitation of the bottles.

It is an object of the invention to provide an improved form of feeding mechanism which will effect the safe and accurate transfer of bottles to the traveling carrier of a capping machine or other bottle-handling machine, which will minimize rubbing or marking of the outer walls of the bottles, which will reduce agitation or jostling of the bottles, which is adapted for high-speed operation, which will accommodate bottles of different diameter, and which is capable of inexpensive manufacture and easy mounting.

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.
