patent-logo
Today in 1985, US Patent 4530631 A was issued, an invention of Elton G. Kaminski and Carl F. McEldowney, assigned to The Stolle Corporation, for their “Pull Tab For Easy Open Can End — Method Of Manufacture Thereof.” Here’s the Abstract:

An easy open can end having a retained tear strip extending diametrically partly across the can end defined by a score line, and a graspable pull tab adjacent and outside the open end of the score line. The pull tab is provided with a nose portion to initiate a tear along the score line upon lifting of the pull tab. The edges of the nose portion are curled into a cylindrical cross-sectional shape to provide a high beam strength and to rigidize the nose portion and to prevent failure by bending before the tear strip is opened. A method for manufacture of the pull tab includes forming at least one relief notch in the peripheral edge of the pull tab blank at the nose end thereof, whereby to relieve compressive forces when the edge is curled, and curling the peripheral edge of the nose portion in successive steps to form an edge portion of continuous cylindrical cross-sectional shape.

patent-logo
Today in 1884, US Patent 302282 A was issued, an invention of Johann Pusch, for his “Apparatus for Racking Beer.” There’s no Abstract, although in the description it includes this summary:

My invention relates to an improved hermetic apparatus for racking beer, and is designed as an improvement on the apparatus described in Letters Patent No. 274,516, granted to me March 27, 1883.

As in the apparatus described in the above, named Letters Patent, the object of this invention is to effectually prevent the escape of the carbonic-acid gas contained in the beer during the process of racking; and the improvements herewith made consist, first, in the novel means employed in connection with the barrel-platform for raising and lowering the same; second, in the novel means for clearing the supply-pipes of all beer after the barrel is filled, and, third, in the novel bung-feeding mechanism, all as will be fully described and claimed.

Patent No. 141072A: Manufacture of Beer And Yeast

By

patent-logo
Today in 1873, US Patent 141072 A was issued, an invention of Louis Pasteur, for his “Manufacture of Beer and Yeast.” There’s no Abstract, although in the description it includes this summary:

The following is a recapitulation of the essential features of this improved process: The wort is introduced in a iling state in the apparatus, on which a cover is then placed, or the cylinder may be entirely closed and communicate with the atmosphere only by means of the pipes, cocks, and long tubes with which it is provided. Boiling water is then thrown on the a paratns, after which it is allowed to cool with or without the assistance of cold water, during which time air or carbonic-acid gas is admitted by the long tube; but previous to this one of the plug on the cover is closed by unplug, through which passes a tube, terminating in an India rubber tube and glass stopper. Pure wort is then fermented by pure yeast, and, when sufficiently advanced, the contents are poured through the tube in the stopper of the pipe on the cover of the fermenting apparatus.

If there is a supply of pure yeast from the preceding operation this may be used, as in the ordinary processes, the vessel being inverted for the purpose, it’ necessary, after fermentation has commenced; but this might lead to great inconvenience at a subsequent period, although the use of pure yeast, manufactured according to this improved process, would of itself form a great improvement on the ordinary process.

With the aid of the microscope and the method of control, before indicated, the change of condition, which might arise under the latter modes of treatment, may bc readily ascertained; but one cooling apparatus be used or a few, only the wort being p 1;- into vets,- (pitched or varnished on the exterior, which are deprived of any germs of disease, either by the use of boiling water or by the recent applying of pitch on the interior.

This invention relates to, the preservation of beer or other liquids; and the object of the invention is to provide a process by which the organic or germ life in the beer is rendered harmless, so that the beer will keep without deterioration for a great length of time.

The invention consists of the process of preserving beer which comprises the steps of placing a suitable preservative substance in a receptacle in contact with the beer to be treated and then passing through said substance, receptacle, and the beer an electric current of high tension, said current being of such direction, strength, tension,and character as to induce a cataphoric transference of said preservative substance through the receptacle into the beer.

The invention consists also in certain other combinations of steps hereinafter described and claimed, all however, involving the same principle of cataphoric action.

patent-logo
Today in 1909, US Patent 928588 A was issued, an invention of Harry S. Cornish, for his “Apparatus for Dispensing a Measured Quantity of Beer.” There’s no Abstract, although in the description it includes this summary:

My invention is primarily designed for dispensing beer and to regulate what is known as the pint trade.

The main object of my invention is to avoid any waste of liquid when changing from one source of supply to another and to insure that the first liquid drawn from the new source will be of the full measured quantity.

To these ends my invention consists in providing an apparatus for drawing a measured quantity of liquid with means for changing from one source of supply to another, when the first has become exhausted, together with means for venting or freeing the air from the pipes and intermediate connections of the empty end of the system previous to connecting the new supply, so that the new supply can immediately fill the empty end and a full measured quantity drawn at the first draft from the new supply.
