By

patent-logo
Today in 1987, US Patent EP 0208450 A2 was issued, an invention of Ronald Shackleton, for his “Beer Filtration.” Here’s the Abstract:

It has been proposed to filter beer or tank bottoms using crossflow filtration. In accordance with the invention, this crossflow filtration is achieved using ceramic membranes. In a particular form shown in figure 1, a two stage filtration process combines the functions of clarification and recovery from tank bottoms. Beer is drawn from a tank 1 by a centrifugal pump 2 to a primary filtration stage comprising a circuit in- cludinga a circulating centrifugal pump 3, a ceramic membrane filter 4 and a cooler 5. A proportion of the circulating liquid is drawn off by a positive pump 8, and passed to a secondary filtration stage, again comprising a circuit including a circulating positive pump 9, a ceramic membrane filter 11 and a cooler 12. A proportion of the retentate is drawn off via a line 14. This retentate is of a pasty consistency and normally has a commercial value, in that it is free of kieselguhr or other filter aid.

Patent No. 2698994A: Beer Can Opener

By

patent-logo
Today in 1955, US Patent 2698994 A was issued, an invention of Walter M. Hansen, for his “Beer Can Opener.” There’s no Abstract, although in the description it includes this summary:

This invention relates to a can opening device and more particularly to a high speed opener of the performating type.

The conventional practice of storing liquids for customer consumption in cans has presented a problem for operators of restaurants and taverns who necessarily handle a large volume of canned liquids in this form such as beer and fruit juices. The usual practice is to punch a hole in the tops of the cans through which the content is poured into the customers glass. Prior to this time such a can punching operation has not only proved dangerous and laborious but also time consuming in that seldom was the punch conveniently located and its use required two hands, one hand to hold the can while the other hand was used to do the punching. Injuries are likely to occur in case of slippage of the can from the hand of the opener.

It is therefore among the objects and purposes of this invention to provide a high speed can opener requiring only a straight thrust by one hand of the operator used to grasp the can wherein a pivoted cutting blade is brought into cutting engagement with the top of the can.

Patent No. 122592A: Improvement In Apparatus For Cooling Beer

By

patent-logo
Today in 1872, US Patent 122592 A was issued, an invention of Morton Andre Foubert, for his “Improvement in Apparatus for Cooling Beer.” There’s no Abstract, although in the description it includes this summary:

The cooling-vessel a is made of a vertical cylinder containing double heads and numerous vertical pipes of small size and placed close together, the pipes opening at their ends through the inner heads, so that the cooling water supplied from the tank I) will run, by the pipe 0, through these tubes and pass up by the elevated pipe (I to the vat e, where the warmed water can be reserved for use in other operations. The beer is supplied by the pipe f and runs from the vat 9 into the upper part of the cooler a, passing gradually downward and running away, by the pipe h, to the refrigerator 7c. The pipes c fare provided with cocks that should have divisions or degrees marked upon them so that they can be opened the proper amount in order that the cooling-water may be supplied in the proper proportion to effect the cooling of the beer that runs through the ap paratus to the required temperature, and I remark that all portions of this apparatus that come in contact with the beer should be tinned to prevent any injury to the same from the copper or other metal made use of for the vessels and pipes. Within the refrigerator it there is a vertical group of pipes, 1, opening at their upper and lower ends into the chambers m, the lower one being connected with the pipe h and the upper one with delivery-pipe n, that leads to any suitable receptacle. The refrigerator is may contain water or ice, as required, and a pipe and cook at 8 may be provided to draw off the beer, if it is not desired to pass all of it through the apparatus, or for emptying the vessel a and pipes l. The pipe and cook at t can be used for admitting steam or hot water for cleansing the vessels a lo, and the pipe and cook a serves as a blow-off for the vessel a.

I claim as my invention The cooler a, constructed as specified. and combined with the vertical group of pipes Z in the refrigerator k, the parts being constructed and connected, as and for the purposes set forth.
