Filed: 1954-03-23
Abstract: 755,552. Valves. GAUTHIER, E. March 23,1954 [April 8,1953], No. 8450/54. Class 135. A valve comprises a packing ring 11 of elastic material through which passes a hollow rod 5 of a piston 4 which is urged towards an abutment 12 by a spring 7. Fluid pressure acting on the piston compresses the spring to move apertures 6 in the piston rod beyond the packing ring 11 and thereby permit the escape of pressure fluid. The piston rod may be chromium plated or otherwise coated to prevent the packing ring 11 from adhering to the piston rod. The piston rod may actuate an electromagnetic warning device. In a modification, the piston rod carries an adjustable abutment to limit its travel in the closing direction. In a further modification, the valve discharges into a chamber fitted with an outlet union, and the piston rod is extended to project from the chamber for manual actuation.

Abstract: 756,235. Velocity-modulated tubes. GENERAL ELECTRIC CO. March 24, 1954 [March 27, 1953], No. 8626/54. Class 39 (1). A high-frequency electrondischarge device for providing two output signals of the same frequency comprises an input resonator 9 for applying an input signal between cathode 2 and grid 4 so as to density modulate the beam, the density-modulated beam exciting resonator 10 at the same frequency as the input and the resonator 10 both giving an external output and reacting back on the beam to velocity-modulate it a drift space 6 in which bunching occurs, the initial density-modulation and the bunching produced by velocity modulation being cumulative, and a second output resonator 22 excited by the finally bunched beam. Outputs are taken capacitively from resonators 10 and 22, and may be used separately or combined, e.g. by a " diplexer." Feedback from either output to the input may be employed to increase the gain. The resonators are preferably of the concentric line type but the input resonator could be a hollow cavity resonator. Impedancematching stubs 15, 16 have movable plungers for tuning and their outer conductors are capaci-. tively coupled to the outer conductor of the input resonator 9 to allow different D.C. potentials to be applied to the cathode and grid 4; 17 is a heater lead. The input resonator is tapered at 18 for matching to a feeder line. Resonators 10, 22 are also tuned by plungers, plunger 20 having two sets of fingers with an intermediate mica ring to enable grids 4, 5 to be at different D.C. potentials. The grids 4, 5, 7 are supported from disc seals. Specification 766,236 is referred to.

Patent GB-776313-A (GB)
Title: Isonicotinamide
Inventor: GASSON EDWARD JAMES
Filed: 1955-03-25
Abstract: Isonicotinamide is prepared by hydrolysis of 4-cyanopyridine in an aqueous medium at elevated temperatures in the presence of a compound having a solubility in the aqueous medium of not more than 0.1 per cent at 20 DEG  C. and a pH value between 8 and 11 in the saturated aqueous solution at the same temperature, terminating the reaction when a hydrolysis conversion of not more than 75 per cent is attained and separating isonicotinamide from the unreacted 4-cyanopyridine. The hydrolysis is preferably conducted at a temperature within the range 100 DEG  to 130 DEG  C.  The aqueous hydrolysis medium may contain a proportion of a water-miscible solvent such as aliphatic alcohols and ketones. Concentrations of 4-cyanopyridine in the aqueous medium are preferably less than 15 per cent by weight when recovery of unreacted 4-cyanopyridine is by distillation and 15 to 30 per cent or more by weight when recovery of unreacted 4-cyanopyridine is by extraction with a suitable solvent.  Ammonia present in the aqueous distillate of 4-cyanopyridine may be removed by means of an ion exchange resin and the resulting solution recycled to the hydrolysis process.  Direct extraction of 4-cyanopyridine from the aqueous reaction mixture may be effected with benzene, toluene, carbon tetrachloride, petroleum ether or chloroform. Specified hydrolysis catalysts are magnesium oxide, magnesium hydroxide, calcium carbonate, strontium carbonate and barium carbonate.  In the Provisional Specification magnesium carbonate is also specified as a hydrolysis catalyst.

Title: Tape drive motor control arrangement
IPC: G11B15/22
Filed: 1966-03-02
Abstract: 1,138,398. Recording and playback. AKAI ELECTRIC CO. Ltd. 2 March, 1966 [3 March, 1965], No. 9153/66. Heading G5R. A tape drive motor control arrangement for a magnetic tape recorder incorporates a motor driven tape feed capstan and motor driven feed and wind up reels, the motors being selectively controlled by push-button mechanisms. The drive and switching circuits are arranged so that the motors continue to run even if their manual on/off control is turned off, until the tape has been completely wound on to one or other reel, or has broken. The presence of the threaded tape, which is held in tension by the reverse operation of the motor on the feed reel, is detected by a tension arm 26 (Fig. 1). When this is swung from its normal position a switch 309 is operated, and this causes the relay coil 96 and hence the solenoid relay 72 to be energized, to cause the operation of the switch 303 (Fig. 2) in the supply circuit. The switch 302 is operated by any push button operation requiring tape drive, so that a bypass circuit is established around the recorder manual on/off switch 301. This circuit will remain closed until no tape is sensed by the arm 26, at which time the tape is all wound on one or other reel or has broken. The relay 72 also controls a mechanical latching engagement so that only if tape is threaded through the recorder will a depressed push-button latch into an operating position. A delay circuit 115- 116 is connected across the relay winding 96, so that if the sensing switch 309 opens there is 1-2 seconds delay before the latch and motor control switches fall out. This ensures that minor variations in tape tension do not cause the recorder to be switched off, and that the motors remain energized until the tape is fully wound on to the wind up reel after the end of the tape has been sensed.
