Title: Improvements in or relating to overspeed limiting devices for rotary systems
Inventor: LANE ARTHUR HAMPTON
IPC: F01D21/02
Filed: 1957-12-23
Abstract: 840,599. Gas turbine emergency brakes. ROTOL Ltd. Dec. 19, 1958 [Dec. 23, 1957], No. 39974/57. Class 103 (1). An overspeed governing device, particularly for gas turbines, comprises pivoted by pin 28 on the end of the rotor a cranked flyweight 27, which is normally retained in retracted condition by a shear pin 29, passing through a hole 30 in the flyweight. If the speed of the rotor becomes excessive the pin 29 shears and the flyweight 27 moves out of the position shown dotted. This produces an out-of-balance force on the rotor which will either cause one of the bearings 16 or 17 to seize up and the rotor 13 to be carried into contact with the casing 15. Although the rotary device as a whole is damaged it is thus brought to an effective stop before the overspeed becomes excessive. The hole 31 is a weight trimming hole acting to balance the part cut away in the slot 26 on the other side. An alternative embodiment is described in which the flyweights have a generally arcuate form and are pivoted about end piece so as to move in a manner generally similar to centrifugal brake shoes.

Filed: 1969-08-12
Abstract: 1,212,817. Making a carbon monoxide-rich gas. METALLGESELLSCHAFT A.G. 12 Aug., 1969 [13 Aug., 1968], No. 40246/69. Heading C5E. In a method of producing a CO-rich gas for oxo-synthesis by steam-cracking a liquid or normally gaseous hydrocarbon over a catalyst, CO 2  is scrubbed out of the cracked gas and recycled to the cracking stage, and at least part of the CO 2 -free gas is separated into a CO and an H 2  fraction, the CO fraction being mixed either with the other part of the CO,-free gas mixture, cr with part of the H 2  fraction. Surplus H 2  is available for desulphurizing the feedstock. If the feedstock is a liquid, all the CO 2 - free gas may be subjected to the separating step, and the feedstock may be pre-cracked over a Ni/Mg silicate catalyst to produce a CH 4 - rich gas which is then cracked with the CO 2  over a Ni/alumina or Ni/aluminium silicate catalyst. The precracking is carried out at 400‹ to 550‹ C., and the main cracking at above 750‹ C. In one example the feedstock is natural gas.

Abstract: 1,242,395. Releasable fastenings; boring earth etc. CEMENTATION CO., Ltd 19 Aug., 1968 [4 Sept., 1967], No. 40271/67. Headings E1F and E2A. A clamping device comprises a ring-like structure carrying, in a plurality of openings at respective spaced apart positions therearound, respective load transmitting members 9 each of which is arranged for sliding movement in one of said openings in opposite directions i.e. towards and away from the structure axis, the member being substantially immovable relative to structure in all other directions, the load transmitting members backing onto flexible means contained within the structure and to which pressure fluid can be supplied to distend the flexible means and thereby cause sliding movement of each load transmitting member in one of said opposite directions whereby in use each load transmitting member can be brought into clamping engagement with a driven member 5a. In the construction shown where the device forms part of a vibrating machine for driving the driven member into the ground or for extracting it from the ground, the ring like structure consists of an annular member 1, a second annular member 2 of greater diameter and plates 4 and 5 which with the members 1 and 2 define an annular cavity 3 in which the flexible member is contained. The openings for the load transmitting members 9 are in the member 1, the driven member 5a being inside the member 1. The flexible means consists of an inner tube 6 and an outer protective cover 7, fluid being supplied to the inner tube via a connection 8. The members 9 include plates 12 which are arranged to present a substantially continuous surface to the outer cover 7 of the flexible member. Instead of the ring-like structure being annular as shown it can have a non- annular configuration. Instead of there being a common cover 7 and tubes 6, each load transmitting member can have its own cover and tube, alternatively there can be a plurality of annular covers and tubes therefore either concentrically or coaxially arranged.

Abstract: 1,272,442. Colour television tubes. GTE SYLVANIA Inc. 13 Aug., 1969 [13 Aug., 1968], No. 40437/69. Heading H1D. The shadow mask 20 of a colour television tube is supported from the envelope 14 by means of a number of mounting members each comprising a bimetallic plate having a portion 40, nearest the face of the tube, attached to the mask frame 22 and another portion 42 attached by means of spring arms 34 to mounting studs 38 on the envelope, the two portions being joined by a tapered corrugation 44. Of the two layers of metal comprising the plate, that having the higher temperature coefficient (e.g. a Ni, Cr, Fe alloy) lies on the outside of the corrugation so that the latter contracts as the temperature increases. Since the deeper end of the corrugation contracts more than the shallower end, the arm 34 is caused to pivot in such a manner that the shadow mask is moved nearer to the face plate. Further, the contraction of the corrugation causes the upper portion 42 of the plate to approach the frame 24 and the arm 34 to pivot on the stud 38 whereby the desired movement of the mask 20 is amplified. This movement preserves the alignment of the mask.

Title: Control system for feeding antidetonant material to the intake of a supercharged internal combustion engine
IPC: F02B37/18
Filed: 1962-10-29
Abstract: 1,031,294. Supercharged I.C. engines; gas turbine plant. GARRETT CORPORATION. Oct. 29, 1962 [Oct. 30, 1961], No. 40857/62. Headings F1B, F1G and F1T. [Also in Division G3] In a supercharged I.C. engine control system the flow of anti-detonant to a nozzle 47 is controlled by an "on-off" valve 42 and a metering valve 50 in series, the valve 42 opens at a predetermined compressor output pressure and the valve 50 is controlled by a diaphragm 45 subjected on one side to the compressor inlet pressure and on the other side to the compressor output pressure. The boost pressure is transmitted through conduit 23 and check valve 24 to pressurize the antidetonant, e.g. water and methanol, in reservoir 22. Antidetonant is fed through conduit 25, valve 42 and valve 49 to nozzle 47 in the induction passage. Boost pressure is applied through conduits 31, 30 to the upper side of spring-loaded diaphragm 37 which moves downwardly. When the underside of spring-loaded diaphragm 45 is subjected to boost pressure, annular shoulder 53 moves upwardly under the induction passage pressure transmitted through conduit 31 into engagement with flange 52 and thereafter further upward movement of diaphragm 45 opens valve 50. During the time when there is no boost pressure applied to diaphragm 37, a switch 74 is closed. At boost pressures which require antidetonant supply switch 74 is opened to place a device 72 e.g. an electrical fuse, which is sensitive to flow of antidetonant, in circuit with an electrically operated valve 71 which is energized into the closed position. Failure of antidetonant flow causes device 72 to open the circuit to de-energize valve 71 which admits boost pressure through conduit 70 to the space above a spring-loaded diaphragm 67 thereby closing an auxiliary throttle 66 to reduce liquid boost pressure. Over-supercharging is prevented by a turbine by-pass 57 as described in Specification 982,047. In a modification, the control of the throttle valve 66, Fig. 3 (not shown) is provided by a valve which is normally kept closed by the liquid head in the antidetonant reservoir. In a further modification a turbine by-pass valve 56, Fig. 4 (not shown) is controlled in response to depletion of antidetonant in reservoir 22 by means of level-responsive valve 84 which opens to connect the boost pressure in the reservoir 22 to the chamber 61 of the by-pass valve operating mechanism. Under low power conditions the attainment of a predetermined compressor inlet pressure causes a diaphragm actuated valve 86 to admit boost pressure from conduit 23 to chamber 61 thereby causing by-pass valve 56 to reduce boost pressure. In a further modification of Fig. 1 leakage of antidetonant when the engine is stopped is prevented by means of a valve 94 which closes passage 32.

Abstract: 919,622. Testing circuit-breakers. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. Dec. 4, 1959 [Dec. 8, 1958], No. 41270/59. Addition to 855,970. Class 37. In a testing arrangement for high-voltage circuit breakers as described in the parent Specification of the kind comprising a circuit for the supply of a high alternating current to the breaker contacts to be tested, and a circuit for supplying a high voltage to the breaker contacts when the latter have reached their open position, and including in the high current circuit a full wave rectifier and an inductive reactance, an auxiliary breaker is included in series with the breaker to be tested which auxiliary breaker is so designed that it starts to open its breaker gap only during the last high-current half wave and interrupts the high-current circuit at the end of this half-wave. An alternating current generator G provides a high current through transformer T to high current circuits I, II including circuit breakers S1 S2 respectively, mechanically actuated in synchronism with the generator frequency and adjusted in such a manner that the rectified current i<SP>1</SP>k is prevented from reaching zero value. Connected across the breaker Sp to be tested is a high-voltage circuit III comprising capacitor C, switching spark gap F and oscillatory choke L. An auxiliary circuit breaker S h  is used to complete the high-current circuit before the testing operation commences and is designed to open the high-current circuit just before the high voltage is applied, i.e. during the last half-wave of the applied current. To achieve this the circuit breaker S h  may be a high speed gas-blast circuit breaker having a fixed annular contact and a pin-shaped movable contact which passes through the annular contact whereby the movement of the movable contact can be initiated before the beginning of the last highcurrent half-wave and the moving pin-shaped contact made to leave the annular contact at the instant when the last half-wave begins. Alternatively, the fixed contact may be designed as a resilient contact. In order to avoid distortion of the current i<SP>1</SP>k at the end of the last high-current half-wave due to one of the two switches S1 S2 already trying to connect in a fresh high-current half-wave, the switches may be interrupted, if they are mechanical switches, by displacing their fixed contacts so that the movable contacts can no longer reach the fixed contacts, or, if they are gas-blast circuit breakers, the extinguishing gas blast may be increased or a more effective arcquenching medium may be directed into the breaker gap after the last high-current halfwave.

Abstract: <PICT:1064012/C6-C7/1> In a process of sintering elongated ceramic, cermet or powdered metal shapes such as UO2 the shape is initially supported from below along two lines parallel with its axis and symmetrically spaced about the lower half of its circumference, and as its diameter decreases due to shrinkage it is supported along a third line parallel with its axis along the lowest part of its circumference, downward compressive forces being exerted along lines parallel with the axis of the shape, said forces being abated as the diameter of the shape decreases due to shrinkage. As shown in Fig. 1 the tube or rod 11 is supported in a trough 10 at points 15 and 16 and an inverted V-trough 18 rests on the upper half of the shape and exerts compressive forces at 22 and 23.  As the shape shrinks it moves into the trough 10 and finally rests on plane 17 and is supported additionally at point 24.  The upper trough 18 due to the shrinkage finally rests on the upper face 21 of trough 10 and the compressive forces on the shape is therefore abated.  In a further embodiment Fig. 3 (not shown) the upper trough is replaced by two metal rods which exert the downward forces.
