Abstract: 1,227,645. Valves. VSESOJUZNY NAUCHNO - ISSLEDOVATELSKY I. PROEKTNOKONSTRUKTORSKY INSTITUT PROMYSHLENNYKH GIDROPRIVODOV I GIDROAVTOMATIKI. 16 June, 1969, No. 30377/69. Heading F2V. A device for dividing liquid flow comprises a 3-way control valve 2 having a spool 3 with channels 14, 16 connecting an inlet 8 of the valve to two outlets A, C, and to closed end chambers 48, 49 ; and a 4-way control valve 5 having two inlets 29, 30 connected to the outlets of the 3-way valve, corresponding closed end chambers 68, 69 and two outlets 10, 11. The flow of liquid from inlet 8 passes to the end chambers 48, 49 and radial holes 50, 51 via constant-section restrictors 42, 43, respectively. From the radial holes, fluid passes to the bores 29, 30, damping holes 66, 67, end chambers 68, 69 and also to the outlets 10, 11, respectively. If the loadings on the outlets 10, 11 are equal, the spools 3, 6 occupy a middle position. An increased resistance in a driven device which is connected to an outlet (say 10) causes a decrease in the pressure drop across aperture 42 and consequently a pressure rise in chambers 68, 48. Only spool 6 moves since the variable-section restrictor equalizes the pressures in chambers 48, 49. Any difference in the axial components of the hydrodynamical reaction forces is compensated by a movement of spool 3. The new positions of the spools 3, 6 ensure equal pressure drops across, the restrictors 42, 43 and hence equal rates of flow from outlets 10, 11. The spool 3 is set in rotation by fluid emergence from the holes 50, 51, which helps to prevent jamming of the spool.

Abstract: 1,238,267. Lighting burners/gas fuelled lighters. APPLICATION DES GAZ. 27 Nov., 1969 [29 Nov., 1968], No. 57981/69. Headings F4F and F4T. Gas fed under pressure to a burner causes the actuating mechanism of a lighting device to act on a spark producing member to produce sparks to ignite the gas. The spark producing member may be a piezo-electric crystal or a flint cooperating with a friction wheel. The embodiment described comprises a gasfuelled lighter in which gas from a detachable reservoir 2 flows to a burner nozzle 29 via conduits 11, 12, 14, 20, 25 and 26 when a push button 43 is pressed to open a closure valve 17 in the conduit 14, the rate of flow being adjustable by a needle valve 23 actuated by a rotatable knob 23a. The conduits 11, 26 are formed in a cylinder 7 closed at one end by a body 36 containing a piezo-electric igniter 35. The other end of the cylinder 7 is closed by a cover 8 in which the conduits 12, 14, 20 are formed. The piezo-electric igniter 35 has a spring-biased actuating head 33 adapted to be acted on by a diaphragm 32, and is connected by a cable 38 to an electrode 31 mounted in an insulating sleeve 10 surrounding the nozzle 29. A conduit 41 connects the conduit 20 with the space between the diaphragm 32 and the cover 8. When the button 43 is released the diaphragm 32 is returned to its rest position by the spring- biased actuating head 33, thus driving gas, trapped between the diaphragm 32 and cover 8, along the conduit 41 and hence to the nozzle 29. Thus a flame at the nozzle 29 burns for a short time after the gas supply is cut off.

The oscillations of a mechanical oscillator, e.g. a timepiece balance, are electromagnetically sustained by a system comprising two complementory transistors 6, 7 connected at the emitters to electrical, supply lines 11, at the collectors via a capacitor to a drive coil 2, and at the bases via capacitors 14, 15 to a control coil 1 which co-operates with magnets to provide an operative control pulse at each half oscillation of the mechanical oscillator, the pulses being alternately of positive and negative sign. The coils 1, 2, Fig.2, co-operate with two pairs of magnets 3-3, 4-4 on a balance 5 in such manner that during each half oscillation of the balance 5 three pulses are generated in the control coil 1, the second only being of sufficient amplitude to render conducting one of the transistors 6, 7 which are biased by resistors in leads 14, 15. Thus in two successive half oscillations of the balance 5 two drive pulses are provided in the drive coil 2 by the transistors 6 and 7 respectively.
