Patent GB-601232-A (GB)
Title: Hydraulic clutch device
IPC: F16H39/06
Filed: 1945-03-12
Abstract: 601,232. Hydraulic clutches. JOHNSON. A. L., and KRAFT, S. A. March 12, 1945, No. 6155. [Class 69 (ii)] In a vane type hydraulic clutch, inlet ports 43 and outlet ports 45, 50 are disposed on opposite sides of abutments 25a, 26a in the casing and hydraulic means are provided for holding the vanes 39 retracted into the rotor against the action of means 40. Lateral projections 95, 100 on each vane engage recesses in the casing to form chambers 96, 101, to which pressure may be applied for vane retraction. The inlet and outlet ports communicate respectively with a reservoir 44 and air-cushioned pressure chambers 53 ; the passages between outlet ports and pressure chambers having connections with the reservoir normally closed by spring-loaded valves. Relative motion between the rotor and casing in one direction discharges liquid into the pressure chambers to build up pressure until the parts are locked together. In the other direction of relative motion, suction is created in the outlet passages thereby opening the said valves and permitting the liquid to flow from the inlet through the reservoir to the outlet ports and permitting free relative movement. As shown, the casings 25, 31 of two such clutches are geared to a reversible drive shaft 10, while the rotor 34 of one is connected by gearing 154, 155 to a unidirectional driven shaft 11 and by gearing 152, 153 to the rotor 55 of the other. The pressure chambers 53 of each clutch are connected by passages such as 127, 130, 131, 132 to the vane retracting chambers 96, 101 of the other clutch. Hence, for one direction of rotation of shaft 10, first clutch casing 25 rotates relatively to its rotor 34 until pressure build-up locks the two together and retracts the vanes of second clutch rotor 55, thereby driving shaft 11 white permitting free relative motion of the second clutch casing and rotor : while in the other direction of shaft 10 drive is transmitted through the second clutch and the vanes of the first are held retracted. In the event of overrunning of the driven shaft, the casing and rotor of the effective clutch move relatively in a direction to cause the liquid to byepass through the check valves from the inlet to outlet ports.

Title: Improvements in or relating to production of fumaric acid
IPC: C12P7/46
Filed: 1940-04-05
Abstract: 547,594. Fumaric acid. PFIZER & CO., C. April 5, 1940, No. 6213. Convention date, Dec. 7, 1939. [Class 2 (iii)] Fumaric acid is produced by fermentation of a carbohydrate mash with moulds or fungi known to produce this acid, under aerobic submerged growth conditions and in the presence of nutrients for the moulds or fungi.

Title: Improvements relating to the manufacture of water gas
IPC: C10J3/00
Filed: 1930-02-25
Abstract: 344,205. Water gas generation. HUMPHREYS & GLASGOW, Ltd., Humglas House, Carlisle Place, London.-(Assignees of Chrisman, C. S. ; Broad Street, Philadelphia, U.S.A.) Feb. 25, 1930, No. 6244. Convention date, May 6, 1929. [Class 55 (i).] In the manufacture of water gas, steam is passed upwards through a bed of incandescent fuel from a point sufficiently above its bottom to leave the base incandescent and unchilled by steam so that it is at a suitable temperature for ignition by the succeeding air blast. The fuel bed is blasted with air supplied through connections 11 and 13, the blast gases passing though the off-take 14 to the superheater 2 and carburetter 3 and thence through a waste heat boiler 4 to the stack. Steam is admitted to the tuyere 10, the height of which above the bottom air inlet may be between 15 and 35 per cent of the depth of the water gas zone. The "run" gases pass through the fuel in the carbonizing zone and the mixed gases pass through off-take 15 to the wash-box. Blue water gas may be bled off through a connection 17 to the carburetter in which oil is injected, the mixed vapours being fixed in the superheater before passing into the generator through 14 to be mixed with the " run " gases.

Title: Improvements in and relating to gyroscopic horizons and verticals
IPC: G01C19/44
Filed: 1939-02-27
Abstract: 528,569. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc. Feb. 27, 1939, No. 6418. Convention date, March 5, 1938. [Class 97 (iii)] In a gyrovertical of the type described in Specification 393,695, the air stream for the erecting force may be decreased without affecting the air stream for spinning the rotor, a valve being provided for operation to eliminate or reduce the errors in the orientation of the gyroscope which the gravity-responsive means would otherwise produce as the result of the action of acceleration forces in, say, turning of the aeroplane. In the form shown, the rotor casing 1 is mounted in the gimbal ring 3 and the air stream for spinning the rotor 6 enters through screen 15 and passes through the trunnions 4, 2 to the jets 8, the air then passing through apertures 16, baffles 17, and aper tures 18, 19 into the casing 5 from which it is exhausted through pipe 14. The separate air stream for the erecting forces passes through a valve 21, 22, screen 20, trunnion 4<SP>1</SP>, 2<SP>1</SP>, to an extension of the rotor casing 1 which is provided with apertures 33, 34 adapted to be covered by pendulous members 35, 36 pivoted on the casing at 37, 38. Eccentrics 39 are mounted on the members 35, 36 to vary their hanging and their lower ends are adapted to engage the casing on excessive movement. When the orientation of the gyro is disturbed by acceleration forces of the aeroplane the erecting forces of the air stream come into play but to prevent or eliminate errors due to these forces on the pendulous members the air stream can be reduced or cut off by means of the valve 21, 22 either by hand knob 25 or automatically by a rate of turn indicator connected to the crank 28. Specification 525,876 also is referred to.

Filed: 1976-02-19
Abstract: 2-Deutero-3-fluoro-L-alanine is converted into its D-isomer in an asymmetrical manner. In this process, the L-isomer is reacted with sodium nitrite to give the corresponding L-2-deutero-2-halo-3-fluoro-propionic acid in solution in an aqueous hydrohalic acid. This L-2-deutero-2-halo-3-fluoropropionic acid is then reacted either with ammonia or with sodium azide with replacement of the 2-halogen substituent by a 2-azido group and subsequent catalytic hydrogenation to give 2-deutero-3-fluoro-D-alanine. 2-Deutero-3-fluoro-L-alanine can be converted into pharmaceutically acceptable salts. The resulting compound can be used for inhibition of the growth of Gram-positive and Gram-negative pathogenic bacteria.
