Filed: 1973-05-24
Abstract: 1414051 Standby supply systems for gas discharge lamp GENERAL ELECTRIC CO 24 May 1973 [24 May 1972] 24782/73 Heading H2H A standby power supply system for discharge devices such as gas discharge lamps comprises a ballast device by way of which the discharge devices are operated from a primary power source and an emergency power source connected to the discharge devices when the primary power source fails, the emergency power source operating at a high frequency such that the ballast device exhibits a high impedance and the emergency power source having a high impedance at the frequency of the primary power source. A lighting system 24 comprises two discharge lamps 66, 67 having heatable electrodes and connected in series between terminals B, C, the lamp 66 having a capacitor 70 connected in parallel therewith. A normal power source is connected to terminals 10 and to terminals 15 the supply at terminals 10 operating the two lamps 66, 67 in the normal way through an inductive ballast 12, whilst the supply at terminals 15 provides signals to inhibit the transistors 25, 26 of an inverter and at the same time charge a battery 35 which forms the emergency source of power. Failure or reduction in voltage of the primary source of power at terminals 10, 15 removes the inhibiting signals on the transistors 25, 26 whereupon the inverter 16 begins to oscillate, the power being supplied by the battery 35. The output frequency of the inverter at the secondary winding 36 of the transformer 30 is of the order of 6À5 kHz and at this frequency the capacitor 70 is effectively a short circuit so that the inverter 16 causes illumination of the lamp 67 only at a reduced light output. At the output frequency of the inverter 16 the ballast 12 forms a high impedance and capacitors 46, 47 which are connected in series with the secondary winding 36 cause the inverter 16 to form a high impedance when the lamps 66, 67 are supplied from the normal power source at terminals 10.

Abstract: 894,398. Fluid-pressure servomotor-control systems; valves ; hydraulic apparatus. HOUGH CO., FRANK G. July 18, 1960, No. 24931/60. Classes 69 (2) and 135. A double-acting ram 12 which is actuated by supplying fluid pressure to either side and exhausting the other side under the control of a selector valve, not shown, is provided with valve means 22 comprising a closure member 15 slidable in a bore 21 to increase or decrease the speed of ram extension in dependence upon the load opposing the extension. With a heavy load fluid passes from the conduit 11 via a groove 24, a valve bore 21 and a groove 23 to the conduit 18, the fluid from the conduit 11 also traversing a passage 37 in the closure member 15 and entering a chamber 14 after opening an adjustably loaded relief-valve 13 seated on a member 15 whereby the latter is maintained in the position shown against fluid pressure in the groove 24 acting on a surface 40, of the member 15 ; fluid from the rod end of the ram passes to exhaust via a conduit 17, a groove 25, bore 21, a groove 26 and a conduit 16. If the load is light the fluid-pressure is insufficient to unseat the relief valve 13 but in acting on the surface 40 moves the closure 15 rightwardly to disconnect conduit 16, 17 and connect the exhausting fluid from conduit 17 to the conduit 18 through a passage 19 and groove 24 whereby the ram 12 extends at a greater speed. Should the load change during the ram extension the relief valve will either be opened or closed to cause a movement of the closure 15 to provide either an increase or a decrease in speed. A slidable element 29 is provided which in one position limits the movement of the closure member 15 and in another position prevents movement of the latter. A bleed passage 39 interconnects the space behind the relief valve 13 with the groove 25. The closure member 15 is also formed with another surface 40a opposite to surface 40 and open to groove 25 to maintain the member 15 in the position shown when conduit 16 is connected to the supply. In another form, the conduit 18 is connected directly to the supply, the groove 23 is dispensed with and conduit 11 is branched from conduit 18. In a further form a simple spool or other valve controls fluid flow from the piston-rod end of the ram to either the respective return line or the other end of the ram, the valve being operated by a load-responsive device.

Abstract: 1,136,470. Pile driving. VULCAN IRON WORKS, Inc. 30 May, 1967 [8 June, 1966], No. 24937/67. Heading E1H. [Also in Division B3] A pile driving drop hammer has its tup raised by pressure fluid such as steam admitted below a piston 25 under the control of a valve 32 operated by means 45, 46, 47 selected to give a normal or a short lift. The semi-rotary valve 32 in chest 31 is actuated by an axial cam 46 as the tup reaches the bottom of its fall, to place duct 34 into communication with the steam admission passage 30, 36. This causes the piston 25 to rise. For normal stroke working the valve 31 is rotated by an axial cam 45 to open duct 34 to exhaust port 35 thereby causing the piston and tup to fall by gravity. The end of the upstroke is cushioned by air trapped above port 38. For short stroke working the valve rocker arm 41 is moved to the right, Fig. 1, by a fluid motor 51 into alignment with another axial cam 47 which effects reversal of the valve 32.
