Title: An improved brewing process, and apparatus therefor
Inventor: SHORE DAVID TEIGNMOUTH
IPC: C12C11/00
Filed: 1960-02-04
Abstract: 938,173. Continuous wort &c. fermentation. A.P.V. CO. Ltd. Jan. 30, 1961 [Feb. 4, 1960; March 11, 1960], Nos. 4088/60 and 8706/60. Class 14 (2). In the production of a potable fermented liquid, particularly beer from hopped wort, spirits from converted grain mash or sugar, cider from apple juice, and wine from grape juice, by continuous fermentation of a fermentable liquid by a fermenting agent (yeast) in a tower-like fermentation zone, the fermentable liquid being fed in at the lower end of the fermentation zone and withdrawn fermented from the upper end, the upward speed of the liquid through the fermentation zone is substantially uniform over the cross-section of the zone, a high concentration of the fermenting agent in the fermentation zone is held in suspension by the upward flow of the liquid and of the gas evolved during fermentation so that the fermenting agent is substantially stationary in the zone, and the fermenting agent carried out of the fermentation zone by the withdrawn liquid is separated, at least a part of the separated fermenting agent being returned to the upper end of the fermentation zone. Hopped brewers' wort and oxygen, air or other nutrient are fed from lines 2, 3, respectively to, and uniformly distributed over, the cross-section (by one or more nozzles 20, Fig. 2, or the jet and baffle arrangement shown in Fig. 3) of, a fermentation tower 3 provided with heating or cooling jackets 4, 5, 6. Fermented wort overflowing into a line 10 passes through a cooler 13 to a yeast separator 14 from which the liquid passes by a line 15, as beer. The separated yeast passes through line 19 to a deflocculation pump 16, the output of which is fed through line 17 to the head of the tower; fermented product can be recirculated from line 17 to either the head or base of the tower. The upper jacket 6 is preferably run at a lower temperature than the jackets 4, 5, so that in the neighbourhood of the off-take 10 the yeast is held back by preferential settling. The tower is effectively free from mechanical supports for the fermenting agent (yeast) and has a vent 23 for the fermentation gases; the tower may be pressurized to 5-10 lbs. per square inch or more. The length may be 22 feet, diameter 2 feet. The secon Provisional Specification mentions the productdion of industrial alcohol from molasses wash.

Abstract: 960,903. Printing machines. ADDRESSOGRAPH-MULTIGRAPH CORPORATION. Feb. 6, 1961 [Feb. 10, 1960], No. 4387/61. Heading B6C. In a hand-operated printing machine a platen carriage carrying a platen roller is movable over a bed on which is arranged in superimposed relationship an upwardly disposed printing plate, inking means and the matter to be printed. The bed comprises a top plate 26, Fig. 3, integral with depending side portions 28, Fig. 1, and end lugs 31, Fig. 7, the latter adjustably mounting end caps 40, Figs. 1 and 3, which serve both as a supporting structure for the machine and as a support for a central rail 42 upon which runs rollers 105 of a guide 110, Fig. 15, forming part of the platen carriage. The carriage also incorporates a saddle-shaped member 120, 121 which mounts, through adjustable eccentric bearings, rollers 135 for engagement with the lower surfaces 28F of the bed side portions 28. The platen roller is mounted in the carriage on eccentrically arranged bushings 147 and 148, Figs. 10 and 12, such that on the return stroke, i.e. to the left as viewed in Fig. 1, the roller is out of contact with the matter-sheets, cards &c.-that has just been printed. The lifting and lowering of the roller relative to the bed is effected by a toothed gear segment 150 fixed to the bushing 148 which engages teeth 153T and 154T, Fig. 7, formed in plastic mouldings secured to the plate 26 in the path of the gear segment 150. In the " before " printing position of Fig. 1 the roller is raised, but on moving the carriage the teeth 153T engage the gear 150 such that the eccentric bushings are rotated to lower the roller for the printing operation. As the end of the printing stroke the teeth 154T engages the gear 150 to raise the roller and this position is maintained throughout the return or non-printing stroke. In the modified machine shown in Fig. 16, the cards or sheets to be printed thereby are of short dimension which enables the removal thereof after a stroke of the platen carriage irrespective of the end of the machine where the carriage happens to be. The platen roller need not therefore be shifted during the course of a reciprocal movement of the carriage and to this end gear 190 and associated teeth 154T, 153T and the various eccentrics are omitted. During the printing operation in both embodiments ink is exuded if the platen roller is impregnated, or " carbon " is offset image-wise if carbon sheets are used in conjunction with a dry platen. Specifications 951,249 and 960,904 are referred to.
