Inventor: WADDINGTON WRIGHT
IPC: C10G45/26
Filed: 1955-09-06
Abstract: <PICT:0820164/III/1> Hydrogen required for the catalytic hydrogenation of a vaporizable hydrocarbon is produced by passing the vaporized hydrocarbon, or a portion thereof, and/or a hydrocarbon-containing tail gas from the hydrogenation, together with steam over a cobalt-molybdenum or a cobalt-molybdenum-potassium catalyst, followed by the removal of all or a substantial part of the water. The reaction is preferably carried out between 450 DEG  C. and 650 DEG  C. at a liquid feed rate not exceeding 5 kg. per kg. of catalyst per hour and an oil to steam weight ratio below 10 : 1.  The process is specially applicable to materials containing sulphur or nitrogen, and especially to the hydro-refining of creosote in one form of the invention, a crude benzole stored in 1 is fed via preheater 3, where it is mixed with steam and heated to 550 DEG  C. to the converter 4, which is packed with cobalt molybdate.  The product H2 is freed from water in condenser 5 and separator 6, and from H2S and CO2 in scrubber 7 and thence to the gas holder 8.  The H2 is compressed to 100 lb/sq. inch by compressor 9.  The benzole from 6 is passed to flash chamber 11 where it is vaporized, and the vapour and gas enter the preheater 12 and reactor 13.  The products are condensed and separated in separator 15.  The liquid is stored in 16 and the gas is mainly recycled.

Title: Improvements in electrical measuring, regulating, indicating or the like devices
IPC: G05B1/04
Filed: 1946-08-26
Abstract: 639,325. Automatic temperature control systems. REGIE NATIONALE DES USINES RENAULT. Aug. 26, 1946, No. 25505. Convention date, Jan. 15, 1945. [Class 38 (iv)] [Also in Groups XXXVI and XXXVIII] In an automatic measuring, indicating or controlling device deflection of a normally central needle of a meter is arranged to break the feed circuit of one or other of two energized electric motors producing torque on a common shaft in opposite directions so that the normally stationary shaft rotates in one or other direction. In the Figure, a rheostat 37 in series with a furnace heating resistance 34 is automatically varied by the shaft until . the temperature denoted by a thermo-couple 35 is restored to' normal. By including a clock controlled resistance in series with the thermo-couple the furnace temperature may follow a predetermined variation. The needle 9 is transversely reciprocated by a cam-operated stirrup 11 so that when deflected it rocks one or other of two pivoted levers 15, thereby breaking spring- controlled contacts in one of the feed circuits of the motors. The levers are so profiled as to be rocked in proportion to the needle deflection. The stirrup may remain deflected for a short instant only so that several potentials can simultaneously be measured. The driven member may directly actuate an indicator or recording pen. Temperature, potential resistance, pH value, or chemical dosage (by measuring the change in potential due to oxidation of solutions), may also be measured.

Title: Improvements in or relating to vehicle hand brakes
IPC: B60T7/10
Filed: 1962-07-03
Abstract: 1,010,511. Fluid pressure servomotor systems. SCANICE-NABIS A.B. July 3, 1962 [July 4, 1961], No. 25535/62. Heading G3P. [Also in Division F2] In a vehicle hand brake lever mechanism (Division F2) a substantially equal braking force may be obtained either by a hand brake amplifier in the form of a fluid-pressure servo device 2 or by manual operation by a mechanical multi-stroke device, the amplifier and the multi-stroke device are mounted together on a frame 20 with direct association with the hand brake lever. Fig. 1 shows an arrangement wherein a pneumatic servodevice 2 of the two-chamber type secured to the frame 20 which also supports a pivotally mounted hand brake lever formed in two parts 8a, 8b and two locking segments 72. Cooperating with the locking segments 72 are two pinions 71 journalled with a locking wheel 70 formed with ratchet teeth to cooperate with pawl members 78 and 75 under the control of a push button 7 and push rod 91. In the released position of the hand brake shown in Fig. 1 the chambers A and B of the servo device 2 (Fig. 2) are in communication with each other through a passage 54 a clearance hole in valve seat 49 and channel members 53 between a valve casing 52 mounted on the diaphragm 51 of the servo device 2. Both sides of the diaphragm 51 are therefore subject to a source of pneumatic pressure and actuation of the hand brake lever in the brake applying direction causes axial displacement of a control rod 39 so that a valve device located in the valve casing 52 is actuated, the control rod 39 is connected to a control piston 40 which, when raised, allows a tubular valve member 46 to rise and shut off the communication between chambers A and B continued upward movement of the piston 40 allows compressed air in chamber B to escape to atmosphere through the channel 54 and hollow member 44a. This action allows the pressure in chamber A to raise the diaphragm 51 and diaphragm rod 44b to assist actuation of the hand brake lever mechanism. Should the air pressure system of the vehicle become inoperative, the brake may be applied by manual operation only such that if the lever part 8a is moved upwards from the initial position shown in Fig. 1 it takes along with it the lever part 8b which, through the intermediary of the links 66, acts upon the valve device of the hand brake servo device.
