Filed: 1963-10-23
Abstract: 992,620. Releasable pipe couplings. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Oct. 23, 1963 [Oct. 25, 1962; June 7, 1963], No. 41850/63. Heading F2G. A quick-release coupling, particularly for gas containers, comprises a first coupling part 24, Fig. 6, provided with a valve 53 kept in closed position by spring and/or gas pressure and a second coupling part 47, Fig. 4, provided with an axially movable valve-operating element 28 and an operating mechanism for moving said element, the coupling parts being provided with locking means comprising a recess 50 in one coupling part and an axially movable rod 40 in the other coupling part, said rod having the same cross-section as the recess, the rod and the recess being so arranged that coupling and uncoupling is possible only when the valveoperating element is in the withdrawn position and that opening of the valve is possible only when the coupling parts have been properly coupled. When the coupling parts are fitted together, radial lugs on the part 47 enters slots 27, 27a in the part 24 and the parts are relatively rotated, in the manner of a bayonet coupling, until the recess 50 in the coupling part 27 is opposite to the end of the rod 40 in the coupling part 47. The parts are then locked in the coupled position by raising the end of a lever 37 so that a forked arm 51 thereon ceases to hold up a collar 43 on the rod 40, the end of which is therefore pressed by a spring 42 into the recess 50. To open the valve in the coupling part 24, the end of the lever 37 is raised still further where another arm 39 thereon engages one limb of a spring 34, having two limbs as shown, causing the other limb to displace a deformable wall 33 which, through a disc 32, presses on the end of one arm of a bell crank 30, the other arm of which moves a valve operating element 28, against a spring 29, which moves the valve stem 54, in the coupling element 24, to valve-open position. In another embodiment, Fig. 9, the rod 71 is moved for locking and releasing the coupling by a lever 78, similarly to the embodiment described, but the valveoperating element 67 is moved to open the valve, when the end of the lever 78 is raised, through the tilting of a lever 83 by a cam surfaces 82 of the lever. In this embodiment a passage 66 and reliefs 68 allow gas to pass into the upper region 85 of the coupling pair 60 and to a reduction valve if desired. In a simpler embodiment. In Figs. 1 and 2 lugs 15, 15a, on the part 12 pass through slits 15, 15a in part 1 and the coupling is completed by rotating 12 through 90 degrees. Further rotation can be prevented by rotating a cam 21 which depresses an element 16 into engagement with a corresponding recess 6 in the part 1. Further rotation of the cam depresses element 16 sufficiently to open the valve 7.

Abstract: 957,597. Incandescent electric lamps. GENERAL ELECTRIC CO. Nov. 9, 1962 [Nov. 29, 1961], No. 42408/62. Heading H1F. An incandescent lamp comprises a sealed light-transmitting envelope containing a filament of carbide of a metal of the group comprising tantalum, hafnium, niobium and zirconium or mixtures thereof, a source of hydrogen and a quantity of uncombined solid carbon which is located in effective range of the atomic hydrogen formed in the vicinity of the filament so that a carbon bearing gas, e.g. a gaseous hydrocarbon is formed which is thermally decomposed at the filament so as to maintain the carbon content thereof at a fixed value and to release hydrogen for continuation of the cycle. The lamp may contain hydrogen and a rare gas at a total pressure approximating to atmospheric pressure. Methane alone or mixed with hydrogen may be used. The source of carbon may be a pellet on the envelope wall or a layer of soot. In one form, the lamp has a small spherical envelope with a punch seal, a pellet of carbon being provided on the envelope wall. In another form, the filament 2a is supported by lead-in wires 3a within a tubular envelope 1a. A metallic screen 6 coated with finely-divided carbon is carried by a support 7 from one of the lead-in wires so that atomic hydrogen formed by dissociation of the filament is carried by convection into contact with the screen where it combines with the carbon to form a hydrocarbon which returns to and is dissociated at the filament. In a third form, a layer of soot is coated on the upper end of the envelope. The lead-in wires may, in this case, be partly coated with glass to minimize the deposition of carbon thereon. The filling may also contain nitrogen or a source of nitrogen such as hydrogen cyanide or ammonia.

Title: Prime mover speed control system
IPC: H02P23/00
Filed: 1975-10-21
Abstract: 1525265 Automatic control of speed GENERAL ELECTRIC CO 21 Oct 1975 [25 Nov 1974] 43129/75 Heading G3R In a speed control system for a fluid driven prime mover, a fluid-flow control valve for the prime mover is actuated according to a phase comparison of digital pulses having frequencies respectively proportional to desired and actual speeds of the prime mover. Any phase difference is either a first or second signal indicative of phase lag or lead, which signals are converted to a D.C. voltage to actuate the valve. As shown, valve 13 controls the steam flow to turbine 11 whose actual speed is detected by a tooth wheel and co-operating Hall effect transducer 33, which produces the digital signal having a frequency dependent upon actual turbine speed. A switch 25 selects either an automatic (e.g. computer set) or manually adjustable voltage, which passes through limiter 27 to voltage controlled oscillator 29 that produces the digital signal having a frequency dependent upon a desired turbine speed. Phase comparator 31 compares the two digital signals to form an output voltage according to any phase difference, which output is summed with a position signal of valve 13 to control an hydraulic actuator for the valve. Since the system uses a phase comparison it is said to produce an anticipatory control before an actual turbine speed occurs. Details of limiter 27 and phase comparator 31 are given in Figs. 3, 5 and 6 (not shown).
