Title: Improvements relating to heating and ventilating systems for motor vehicles
Inventor: GRIFFIN CHARLES ARTHUR
IPC: B60H1/24
Filed: 1957-11-15
Abstract: 846,157. Ventilating vehicles. MORRIS MOTORS Ltd. Jan. 30, 1959 [Nov. 15, 1957], No. 35613/57. Class 137. In a heating and ventilating system for a motor vehicle, an enclosed body 9 from which the air intake 13 of the engine 1 is arranged to extract air, so long as heating is required, is maintained substantially sealed against ingress of air except for an inlet 8 through which heated replacement air is induced to flow continuously because of the suction of the engine (Fig. 1). This air passes through the hottest zone 4 of the gilledtube radiator 2 in the liquid-cooling system of the front engine 1 and the duct 7, its supply and distribution in the body 9 being controlled by flap 16, 17 and 10, whereby the duct 7 is closed, the intake 13 is shut off from the body 9 and an intake 18 is opened to the engine compartment when heating is not required, the supply of heated air then entering the compartment through a duct 19 opened to the chamber 6. Heated air can be admitted to windscreen-demisting nozzles 12 through a pipe 11 adjacent the valve 10. With a liquid-cooled rear engine 20 (Fig. 2) the impulsion of the air through the heating zone is assisted by the action of an engine-driven fan 22, the air passing from a chamber 25 into a duct 29 leading to the vehicle body, although some or all may pass through demisting nozzles, the engine,drawing air from the interior 26 through a duct 27 and cleaner 28. When heated air is not required a valve 30 closes the duct 27, and the cleaner 28, receiving air through louvres 23, communicates with the engine compartment, a valve 31 shutting off the air to the duct 29 and diverting it to outlet louvres.

Title: Dynamoelectric machine
IPC: H02K9/24
Filed: 1973-07-27
Abstract: 1398507 Cooling dynamoelectric machines GENERAL ELECTRIC CO 27 July 1973 [31 July 1972] 35871/73 Heading H2A [Also in Division F4] In a dynamoelectric machine 11, e.g. a turbine generator, having within a gas-tight outer casing 15 a gas coolant, e.g. hydrogen, and dynamoelectric machine parts having a liquid coolant, e.g. water, distributed therethrough, there are provided a liquid coolant system for insulating the liquid coolant through the machine parts, and a flow surge device providing a temporary surge of liquid coolant to the system, the surge device comprising a surge tank 65 interconnected with the system and containing a liquid coolant supply at a higher pressure than that of the coolant in the system, a valve 79 downstream from the tank 65 and positioned between the tank and the system, and an actuator 85 for tripping the valve 79 to cause the liquid in the tank to flow into the system. Thus a temporary surge of higher velocity liquid, determined by the time taken to empty the tank 65 down to the level of a shut off loop 81, is caused to flow through the machine automatically in response to signals fed into the actuator 85 via three leads a ... c; the lead a connects to a temperature sensor 87, e.g. thermocouples, which sense overheating in the stator armature winding 22, the lead b connects to a current transformer 91 which senses any overload in the armature winding, and the lead c connects to a timer 95 to flush the system at regular intervals to sweep out any foreign particles lodged therein. The machine parts liquid cooled by the system are the stator winding holder conductors, and possibly portions of the stator core 19 and the rotor 25. The normal flow is pumped at 45 from a storage tank 39 through a heat exchanger 49, a check valve 51, and a filter 52, and a demineralizer and deionizer. A differential pressure regulator 55 connected to the casing interior and to the system maintains the liquid at a lower pressure than the gas, and any leakage within the machine, which thus would be of gas into the liquid, is detected by a gas monitoring and warning system.

Title: Fuel supply systems for internal combustion engines
IPC: F02M3/05
Filed: 1970-07-24
Abstract: 1321254 Spray carburetters CHRYSLER FRANCE 24 July 1970 [16 Oct 1969] 36015/70 Heading F1B [Also in Division F2] A regulator 10 closes the idling circuit of a carburetter during rapid deceleration of the associated I.C. engine. The regulator comprises an outer casing 11 containing a resilientlymounted hollow piston 20 therein which, in turn, contains a resiliently-mounted inertia element 30 resiliently carrying a valve member 37. The piston 20 is subjected via conduit 4 to manifold vacuum and via conduit 5 to vacuum from a location upstream of the carburetter throttle valve P when the latter is closed. During normal engine speed the piston 20 assumes an equilibrium position in which land 21 closes the fuel inlet connection 12. During idling and slow running of the engine the land 21 uncovers at least partly the connection 12 so that fuel is supplied through connection 12, ports 22 in piston 20, longitudinal slots 32 in element 30, open valve assembly 26, 37 and conduit 3, to idling jet GR. Abrupt engine deceleration causes a sudden increase in manifold vacuum resulting in abrupt upward movement of piston 20 and thereby rapid closure of valve 37 by inertia element 30. Thus idling fuel flow is immediately interrupted by valve 37 and subsequently by closure of connection 12 by land 21a. Moreover, the suction created by the upward movement of piston 20 prevents fuel downstream thereof from discharging through the idling jets. The subsequent relative slow decrease in manifold vacuum causes progressive return of the piston.

Title: Control system for textile spinning and twisting machines
IPC: D01H13/16
Filed: 1959-10-27
Abstract: 917,105. Counters. ADAMS Inc. Oct. 27, 1959 [Nov. 3, 1958], No. 36358/59. Class 106 (1). [Also in Group IX] A broken and/or slack ends indicator in a ring spinning or twisting machine comprises a magnetic coil pick-up positioned adjacent each ring traveller path so as to establish a voltage during normal operation of the machine, and a sensing means actuated by lessening or absence of such voltage when the traveller slows or stops. A scanning mechanism electronically linked to a relayoperated signal lamp and counter provides continuous indication and record of traveller conditions for all the spinning &c. stations. Each pick-up, Figs. 2 and 3, which is mounted on the ring- rail, Fig. 1 (not shown), comprises a permanent magnetic core 16 surrounded by a coil 17 across which an alternating voltage is induced by the periodic passage of the ring traveller B through, and the resultant distortion of, the magnetic field. One end of each coil is earthed, at 6, and leads 18 are each connected to one of spaced contacts 19 of scanning mechanism C, Fig. 4. A constant-speed, motor-driven rotor 20 successively engages contacts 19 to transfer the voltage obtaining thereon, through a slip-ring (not shown) to the grid of amplifier tube 27. Amplified voltage is fed to control grid of tube 29 through a coupling condenser 28, having a filter 28a, and the voltage from plate of tube 29 is fed through coupling condenser 30, having an inductance filter 30a, to the cathode of rectifier tube 31. The negative output voltage from plate of tube 31 is placed on the control grid of a thyratron E serving as a sensitive switch, i.e. firing when the grid voltage falls below a predetermined value and maintaining a maximum output almost instantaneously, to operate a relay coil 33 which, in turn, operates double relay switches 34 and 35 to energize a coil 36 of a counting mechanism and to operate a locking relay 37 for closing contacts 39 and completing the circuit across a signal lamp 38. A reset switch 40 is employed to unlock the holding mechanism actuated by relay 37 by energizing a coil 41 which opens contacts 39. If adjacent ends should fail at the same time, an artificial injection voltage is applied, through sets of electrically connected rings 23 and 24 and a rotor 25 synchronized with rotor 20, to the control grid of tube 27 in order to reset the relay mechanism and thus ensure that each fault is counted.

Abstract: 1,075,756. Making electron discharge devices; removing metal by fusion; soldering. GENERAL ELECTRIC CO. Sept. 4, 1964 [Oct. 3, 1963], No. 36450/64. Headings B3A, B3R and B3V. [Also in Division H1] In making an electron discharge device a body is positioned in or so as to close an envelope having a transparent segment and a coherent light beam is projected through the segment on to the body to heat the body and form an aperture therein. In making a light valve an electron gun (14), Fig. 1 (not shown), comprising a body (16), Fig. 2 (not shown) a box (18), a spacer (20), an end element (22) and electrodes (28, 30), Fig. 3 (not shown), is assembled in a jig and heated in a vacuum chamber mainly by radiation from the container which is heated by an induction coil arranged inside or outside of the chamber to effect brazing of the components by brazing material (19) and outgassing of the components. The gun is then hermetically sealed to a writing chamber envelope (12) by glass sealing and a vacuum pump (39) evacuates the envelope through a tube (40). Elements within the envelope are heated for outgassing by induction heating apparatus (44) and then the tube (40) is sealed. A coherent light beam generator (46) projects a beam (47) through a lens (48), through a transparent window (49) in the envelope, through a transparent disc (50) at a point bare of conductive substance (52) and through an aperture (53) in a light shield (54) on the end of element (22). The beam produces an aperture in the end of the element (22). The beam generator (46) comprises a laser having a synthetic ruby rod (60), Fig. 6 (not shown), doped with chromium about which is arranged a helical xenon-filled coil (61), one end of the rod having a deposited silver surface (62) for providing 100% reflection and the other end being coated to provide 90% reflection. A trigger pulse voltage derived from a source (65) is stepped up to 50 KV by a transformer (66) whose secondary winding is coupled to a trigger rod (67) which initiates discharge of the gas in the coil (61). The energy for maintaining the discharge is derived from a capacitor (68).

Title: Improvements in and relating to the production of xylene isomers
Inventor: FITT JOHN STANLEY
IPC: B01J21/20
Filed: 1961-10-17
Abstract: In the production of a desired xylene isomers from a mixture of isomers comprising a distillation step for concentrating the xylene isomers from a mixture containing them, a separation step for recovering the desired isomer and an isomerization step for isomerizing the residue, the isomerization is effected by passing the vaporous xylene mixture free from permanent gases over a fixed bed of catalyst and passing the vaporous effluent without condensation to the distillation step.  The initial feedstock may be fed into the distillation step or the isomerization provided the feed to the latter contains at least 50% by wt. of xylenes. If para-xylene is the desired product it is separated by crystallization.  Isomerization is effected at 375-550 DEG  C. over silica-alumina, halogenimpregnated silica-alumina or supported platinum. The first distillation after the isomerization is preferably a topping column followed by a tailing column and heat from the reaction effluent may be supplied to the reboilers or to the reaction feed.  The catalyst is regenerated at intervals with an oxygen-containing gas at 450-550 DEG  C., preferably increasing the temperature during the regeneration from the lower to the upper limit and increasing the oxygen content simultaneously, e.g. from 1% to 20% by volume.
