Patent GB-191732-A (GB)
IPC: C06F1/08
Abstract: 191,732. Duhanot, E. Jan. 11, 1922, [Convention date]. Matches.-Relates to means for setting match sticks in position in carrier plates, for example of the kind described in Specification 174,604. The setting device comprises a table 19 located beneath a hopper 20 and slidable in guideways 27. A comb-like element 28 is interposed between the hopper and table, the comb-teeth corresponding to spaces 29 between grooves 30 in the table for receiving match-sticks to be placed on the bars 1. Vibratory movement is supplied to the comb, as by means of a spring-pressed roller 32 and cam disc 33 for the purpose of causing the sticks to sink between the comb-teeth. Reciprocation of the table enables the sticks to drop naturally into the grooves 30 and then to be inserted into the carrier plate 2. Movement of a handle 36 causes the comb to become stationary and so discontinues the positioning of the sticks. To clear the comb and grooves of match fragments one or more movable rakes are fitted to the back of the comb with projections engaging between the comb-teeth, the fragments being driven out through brushes or pivoted doors at the foot of the hopper. The grooves 30 are cleaned by means of a jet of air issuing from ports in a hollow cylinder 41 which communicates with a compressed air supply pipe 45; also a portion of the periphery of the cylinder carries rows of teeth which engage the grooves when the table is moving rearwardly.

Title: Improvements in or relating to air-flow control in gas turbine power plants

Abstract: 1,097,594. Fluid-pressure servomotor systems. PLESSEY-UK Ltd. May 7, 1965 [May 8, 1964], No. 19186/64. Heading G3P. [Also in Division F1] A gas turbine plant comprises an air compressor 1, combustion equipment and turbine, a Venturi 3 being disposed in the outlet duct from the compressor, the pressure difference sensed by this Venturi being applied to a spring-loaded pilot valve which is so arranged that when the pressure difference falls below a predetermined value, a servomotor is operated to remove a force which normally holds a blow-off valve 9 closed. Means are also provided which prevent the blow-off valve from opening unless the pressure in the duct exceeds atmospheric pressure by a predetermined amount. The assembly shown comprises a pilot valve 19 disposed in a bore 20, the pilot valve having an internal bore 25 and being urged into contact with the valve seat 18 by a spring 24. A diaphragm 23 is disposed in a chamber 22 dividing the chamber into two separate compartments, the right-hand compartment communicating through duct 6 with the throat of the Venturi 3 and the left-hand compartment communicating through ducts 25 and 7 with the higher pressure at the outlet of the Venturi. In normal operation therefore the greater pressure at the left-hand side of the diaphragm acts to move the pilot valve 19 to the right against the action of the spring 24, the pressure being communicated through duct 16 to the cylinder 13 at the right-hand side of the piston 12. The piston 12 is therefore moved to the left against the action of the spring 15, the piston abutting the stem 10 of the valve member 9 which thus maintains the valve in contact with its seat 8 so preventing blow-off of air from the duct 2. Should the flow of air from the compressor be reduced, the pressure difference across the Venturi will also be reduced and the pilot valve 19 will be moved by the spring 24 against the seat 18. The pressure in the cylinder 13 will leak to atmossphere through the restricted opening 26 and the piston 12 will move to the right by the force of the spring 15 and the blow-off valve will be opened by the pressure of air within the duct 2. The object of the invention is to prevent surging in the compressor at low loads. The blow-off valve 9 is prevented from opening during starting of the engine by means of a light-spring 14. In a further embodiment Fig. 3 (not shown) the diaphragm acts to make or break a pair of electrical contacts so that in normal operation when the pressure difference in the ducts 7, 6 is greater than a predetermined valve the contacts are not closed and the electric actuator 28 acts to maintain the blow-off valve closed; when the pressure difference falls to the predetermined value the contacts are closed and the actuator 28 acts to open the blow-off valve so that the compressor may deliver a certain minimum flow. A minimum pressure signal is arranged to prevent the blowoff valve opening during starting.

Abstract: 728,345. Semi-conductor devices. STANDARD TELEPHONES & CABLES, Ltd. July 10, 1953 [Aug. 12, 1952], No. 19226/53. Class 37. A process for electroforming a semiconductor device comprises passing a current through a metal electrode having a coating of significant impurity material and a metal which does not affect the semi-conductor conducting properties, so as to transfer some of the impurity into the surface of the semiconductor. Several electrodes with different impurities may be utilized successively. The electrode may be coated with alloy consisting basically of tin, lead or germanium or high melting-point elements such as tantalum, tungsten, vanadium or molybdenum, with acceptor impurities preferably from the third column of the periodic table or donor impurities from the fifth column of the table. This is placed in contact with the semi-conductor, and a strong electroforming pulse applied to convert the semi-conductor to P or N type material by using acceptor or donor impurities respectively. Two electrodes coated with donor and acceptor impurities respectively may be used successively in two electroforming operations on the same part of the semi-conductor to provide an outer layer of one conductivity type superimposed on an inner region of the opposite type as in the Figure, which shows the electroformed portions of a semi-conductor suitable for the emitter and collector electrodes of a transistor. Reference is made to Specifications 686,907 and 686,948, [both in Group XXXIX].

Filed: 1949-07-26
Abstract: 661,338. Impedance and power factor measurements. RADIO CORPORATION OF AMERICA. July 26. 1949 [July 27,1948], No. 19636/49. Class 37. The resistive and reactive components of an unknown impedance, as well as the loss angle of paramagnetic core material, are measured by developing a voltage determined by the impedance, developing voltages corresponding to the resistive and reactive components of this voltage, and adjusting their magnitudes to balance the first voltage and produce a null indication. The impedance 32, Fig. 1, to be measured is connected in series with the primary winding 12 of a vario-coupler 10 and a resistor 16 across a source of alternating voltage 34. A second vario-coupler 18 has its primary winding 20, shunted by a capacitor 26, connected in series with a resistor 24 across the source 34. The secondary windings 14, 22 of the vario-couplers 10, 18 are connected across the terminals 28, 30 of the impedance 32 in series with an ammeter 36. The vario-coupler 10 is adjusted to give a minimum current through the instrument 36, its setting then giving the value of the reactive component of the impedance 32. The vario-coupler 18 is then adjusted to give a minimum current through the instrument 36, its setting then giving the value of the resistive component of the impedance 32. In a modification, Fig. 2, for determining the loss angle of a paramagnetic core 40, the impedance 32 is replaced by a primary winding 38 on the core 40, a secondary winding 42 being connected in series with the secondary windings 14, 22 and the instrument 36. The vario-couplers 10, 18 are adjusted to balance the reactive and resistive components of the voltage induced in the secondary winding 42, the ratio of the resistive to the reactive component giving the tangent of the loss angle of the core 40. The windings 38, 42 may each consist of a single turn. For use at high frequencies two sections of wave-guide 40, 42, Fig. 3, are provided for each of the variocouplers. The primary windings 12, 20 are fixed in the guides, the secondary windings 14, 22 being slidably mounted for balancing. Electrostatic couplings may be employed instead of electromagnetic.

Filed: 1957-06-20
Abstract: 842,687. Casting-processes. DAUSSAN, H. J. June 20, 1958 [June 21, 1957; Nov. 27, 1957; April 25, 1958], No. 19785/58. Class 83 (1). [Also in Group XXIX] The top surface of a poured ingot is cooled so that the solidification progresses radially towards the centre of said surface, by providing a cooling-effect on a substantially peripheral and annular portion of said surface by evaporation, under the effect of the heat of said metal, of a liquid given by a cooling-agent which is supplied over or on said peripheral portion without possibility of violent contact with the poured metal. The coolant may be a liquid such as water, or a liquid solution such as an aqueous solution of sodium silicate, or an agent containing water-of-crystallization or constitution or both, such as borax, boric acid or a mixture thereof, or an aqueous solution of hydrated neutral carbonate. In one embodiment, when casting unkilled steel, Fig. 1, an annular vessel A<SP>1</SP> of, e.g., steel, cardboard, thick paper, wood or plastic, receives water 7, or a liquid solution, or a product containing water-of-constitution or crystallization, or a fibrous or spongy mass, or a granular, powdered, or porous mass capable of absorbing and retaining liquid while permitting evaporation. The central passageway 4 may be supplied with, e.g., aluminium to exert a calming effect on the steel, or active elements such as borax, fluoride of calcium or sodium, hydrated sodium carbonate, slaked lime or excess silica in hydrated sodium silicate. In a somewhat similar arrangement for bottompouring, an exothermic material is supplied to the central passageway. In a modification, Fig. 8, a dished support A<SP>4</SP> is formed from corru-, gated fireproofed paper, cardboard, &c., Fig. 12, so that it comprises vertical passages 31, and is supplied with coolant from overhead pipes. The deformation of the coil of Fig. 12 to produce the dish-shaped member, results in a deformation of the passages, so that a progressive closure is obtained which increases inwardly of the support so that the cooling effect decreases towards the centre of the support. In a further modification, supports A<SP>5</SP>, Fig. 17, made from corrugated strip E, Fig. 20, deformed to obtain a progressive closure of the vertical passages, are supplied with coolant from sprayheads 121. A variation of cooling may be obtained by opening or closing the central-area of the spray-head by a flap 134, Fig. 21, or an independent coolant supply may be made to the centre of the spray-head, Fig. 23.

In a bottle cap-making machine as described in Specification 646,552 wherein a bottle cap is stamped out and formed from a strip 4 of foil by a punch assembly 3 and a die assembly 2, the assembly 3 includes an annular shearing ring 12 and a cap-forming punch 17 which is carried on a plate 9 mounted by readily releasable screws 16 over an aperture 11 in the wall of the machine, so that the punch 17 may be readily removed outwardly through the aperture without affecting the setting of the shearing tools. As shown, the wall 1 has a boss 13 carrying the shearing ring 12. The plate 9 has a spigot 10 for location in the aperture 11 and also carries a member 18 for embossing the lettering on the cap. A spring- loaded ejector ring 21 surrounds the punch 17. The die assembly includes a fixed cylinder 27 in which a plunger 28 is moved by a link 29. In operation, as the plunger 28 advances, a spring- loaded ring 39 first clamps the foil against the shearing ring 12 and then a spring-loaded ring 42 clamps the foil against the punch 17. A shearing member 33 then co-operates with the shearing ring 12 to stamp out the cap and further movement of the member 33 causes it to press back the ejector ring 21 and to form the cap about the forming punch 17. The inner surface of the shearing member 33 thus serves as the forming die. A rubber pad 38 presses the cap against the embossing member 18. Upon retraction of the die, a spring 24 forces ejector ring 21 forward to eject the cap into a shoot 45. Should caps jam up in the machine, the punch is pushed back against strong springs surrounding the shanks of screws 16 to prevent damage to the punch or die.
