Title: Improvements in periodically acting absorption or adsorption refrigerating apparatus
IPC: F25B17/00
Filed: 1936-05-15
Abstract: 474,924. Refrigerating. HERRMANN, R., and SKUTTA, T. May 15, 1936, Nos. 13778 and 13779. Convention dates, May 15, 1935 and Feb. 18, 1936. [Class 29] Absorption machines and systems.-The electrically - heated generator - absorber 1 of a reversing-machine is enclosed in a finnedjacket 8 filled with a liquid having in solution a gas, e.g. ammonia, or a compound, e.g. ammonium bicarbonate, which dissociates into gaseous form when heated, said liquid being forced out of the jacket into a tank 11 at the beginning of generation by the pressure of the gas evolved therein and returning thereto at the end of generation. The generator-absorber is provided with a central tube containing a heating filament and having around its upper end a cup 5 containing liquid from which gas is quickly evolved to force the liquid from the jacket. Containers for a heat-absorbing substance, such as paraffin wax, may be placed between the fins on the jacket. In a modification, the tank 11 is replaced by a finned vessel enclosing the condenser 7. In another arrangement, the liquid displaced from the jacket passes into an auxiliary tank 16, Fig. 3, connected to the vessel enclosing the condenser. In a further modification, the, jacket is divided by a partition 21, Fig. 5, into intercommunicating compartments 9, 19<1>, the compartment 9 containing the horizontally disposed generator-absorber 1<1>, while the other forms a liquid heater. The gas evolved in the heater passes through a pipe 24 into the compartment 9 and displaces the liquid therefrom. In a variant of this latter modification, the generator-absorber and the liquid are heated indirectly by a liquid, e.g. glycol, circulating through a heater 25, Fig. 6, and a vessel 28 in the jacket 8. In another arrangement, the tank 11, Fig. 9, for receiving the liquid displaced from the jacket is connected to a tank 11<1> containing a heating filament 4<1> which, at the end of generation, is switched on to generate gas, the pressure of which accelerates the return of the liquid from the tank 11 to the jacket. In a still further modification, the filament 4<1> of the tank 11<1> is switched on at the same time as the filament of the generatorabsorber, the heat evolved being stored in a mass, e.g. of paraffin wax, enclosed in a vessel 3<1>, Fig. 11, which acts as a heat accumulator and effects the generation of gas to return the liquid to the jacket at the end of generation. The wax may, however, be heated by refrigerant vapour passing from the generator-absorber to the condenser.

Title: Improvements relating to the manufacture of pressed yeast
IPC: C12N1/02
Filed: 1934-05-15
Abstract: 414,334. Yeast. RAMESOHL & SCHMIDT AKT.-GES., Oelde, Westphalia, Germany. May 15, 1934, No. 14640. Convention date, June 26, 1933. [Class 14 (ii).] In the manufacture of pressed yeast, the washing water employed in the washing operation is at the same time utilized as a driving substance for the yeast milk to be conveyed. According to one embodiment of the invention, yeast is first treated in a group of centrifugal separators 1, then discharged into funnels 3 which are connected to a conduit 4 in which an injector 5 is inserted, so that the washing water conveyed thereto through a conduit 7 serves as a driving liquid for carrying the yeast milk to a second group of centrifugal separators 2. A container 6 with baffle plates, or a similar device, is provided in the conduit leading to the second group of separators in order to enhance the mixing of the yeast milk and water. A third group of separators may be employed, if desired. The funnels 3 may be dispensed with, the conduit between the two groups of separators being a closed one. A single group of separators may be used for both separating treatments, by arranging a collecting vessel above the separators 1. A manometer is preferably interposed in the feeding conduit for the washing water behind the stop valve in order to control the amount supplied. When employing the apparatus shown, less washing water is required, since the concentrating capacity of the separators may be fully exploited without risk of obstruction in the conveying conduits.

Title: Improvements in or relating to magnetic recording and/or reproducing apparatus
Inventor: STONE ALAN
IPC: G11B5/17
Filed: 1955-05-21
Abstract: 802,210. Magnetic recording and reproducing apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. May 7, 1956 [May 21, 1955], No. 14705/55. Class 40 (2). In a magnetic record apparatus having two transducing heads having gaps in planes not greater than 45 degrees to each other, mutual inductive interference is reduced by arranging the axes of the inductive windings on two adjacent heads to be at right angles to each other. The arrangement is described with reference to an embodiment for a data storage apparatus in which two heads 1, 2 engage an identical endless track on a cylinder. In order that an immediate output of the signals, having a square waveform, may be obtained irrespective of the relative rotational position of the cylinder the signals are initially recorded by head 2 via an amplifier 14, read by head 1 and fed back via amplifier 16 and clipping circuit 17 to the head 2 which re-records them. Thus at any time the circulating data can be abstracted from the leads 18 connected to amplifier 16. In view of the very much larger signal current in head 2 it is therefore essential that inductive coupling be reduced to a minimum in order that the signals read by head 1 are not swamped. Specifications 599,751, 642,136 and 707,634, [Group XIX], are referred to.

Abstract: 946,267. Feeding webs. AMPEX CORPORATION. April 17, 1962 [May 4, 1961], No. 14945/62. Heading B6B. [Also in Division G5] A pinch-roller 23 is drivingly engaged with a tape capstan 22 by applying timed impulses to a coil 72, Fig. 6. The member 99 twists a torsion bar 71, Fig. 4, initially adjustable by means, Fig. 5, to centralize the bar 99, and a shaft 43 such that a pinch-roller carrier 36 is advanced towards the capstan 22, the pinchroller being continuously driven by a belt 64 from the capstan at a slightly higher peripheral speed. At the half-way point in the travel of the carrier 36, the current is cut-off from the coil 72 and the carrier decelerates in its movement due to the spring bar 71 such that the pinch-roller arrives with substantially zero impact. The current is then re-applied to the coil 72 to hold the pinch-roller in driving engagement, the zero impact preventing bounce and the excess peripheral speed being arranged to be dissipated in accelerating the tape 14 to operating speed, the tension of the belt 64 being now sufficiently reduced to allow slip. A tape brake 18, 19 may be engaged by similarly timed solenoid means (not detailed) when the pinch-roller is disengaged, a coil 72a may be energized to widen the roller/capstan gap for tape-threading and a duplicate set of members, referenced /a may provide reverse drive, in conjunction with conventional spool/ vacuum column means (Fig. 1, not shown).
