Title: Improvements in or relating to control equipment for rectifiers
IPC: H02M7/15
Filed: 1948-05-19
Abstract: 646,240. Rectifying; automatic voltage control systems. HIGHAM, E. H., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 19, 1948, No. 13558. [Classes 38 (ii) and 38 (iv)] The output of a rectifier comprising one or more discharge valves V1, V2 with .ignition electrodes is controlled by the change in phase of the A.C. supplied to the electrodes by a circuit including a saturable inductance D having a D.C. winding fed from a circuit comprising discharge tubes V5, V6 in which a controlling voltage is compared with another quantity. The variable controlling voltage is derived from a potentiometer N across the D.C. output, and applied to the grid of valve V5 from a potential dividing circuit comprising resistance R1 and valve V4 across an amplifying valve V3. Valve V6, which has a common cathode resistance R2 with V5, is controlled by a steady grid bias derived from resistance R3, and neon tube V7. Windings P, P1 of the saturable inductance D are energized by the D.C. difference of the outputs of valves V5, V6, and the dephased voltage appearing at the junction of resistance R4 and saturable inductance D energized in series from mains transformer T3, is amplified by valve V8 and fed to the rectifier grids through transformer T2. The supply to the grid of V3 may be derived from the output potential so as to maintain this constant.

Title: Improvements in and relating to automatic brakes for gramophones
IPC: G11B17/02
Filed: 1929-05-02
Abstract: 330,370. Spratt, H. Hart-. May 2, 1929. Brakes.-A brake pad 9 is fixed to an arm 8 pivoted on a screw 10 fixed to a sliding plate 6, the latter being guided by the head of the screw 10 which engages in a slot 1<a> in a base-plate 1 and by a pin 3 on the base-plate 1 which engages a slot 5 in the member 6. Another sliding plate 16<a> has pins 16 guided in the slot 5, and has pivoted to it a pawl 17 which engages the slide 6. A rod 19 is pivoted at one end to the pawl 17 and at the other end to a plate 20 fixed to the tone-arm a. The arm 8 is held normally in the position shown in Fig. 1 by a spring 14. To set the apparatus, the tone-arm a is moved to the right, Fig. 3, into the position of Fig. 1 until the pawl 17 abuts and is disengaged from the member 6 by an adjustable stop 28 on the base-plate 1. The slider 6 then moves to the left under the action of a tension spring 11 and the brake pad 9 abuts a flange b on the underside of the turntable, the movement of the pad 9 being limited by a stop 29. A spring 15 presses the pad 9 against the flange b. The tone-arm a is now moved into the position shown in Fig. 3, that is, the position it occupies at the end of reproduction or to any other position it is to occupy when the brake is to be applied, and the apparatus is then ready for use. Outward movement of the tonearm causes the link 19 to move both sliders 6, 16<a>, and the brake pad 9 away from the rim of the turntable, and allows the latter to rotate. During reproduction, the arm 19 and sliders 6, 16a move gradually to the left, Fig. 1, until the parts take up the positions they had when the brake was set, when the brake pad engages the turntable and the latter is stopped. The pivot 10 for the arm 8 is capable of a limited longitudinal movement relatively to the slide 6 to prevent the brake from being alternately applied and released if the record should have an eccentricfinishing groove.

Filed: 1951-06-11
Abstract: 697,759. Moulding meat products. HOLLYMATIC CORPORATION. June 11, 1951 [Sept. 16, 1950], No. 13796/51. Class 87 (ii) Material in a hopper 10 is forced into a mould cavity 14a in a reciprocating table 14 by oscillating rams 17a. The table is moved to the left by levers 25, 26 to bring the mould opening opposite an ejector 41. As the table moves to the left. a cam 55 allows a lever 54 to swing upwardly and a spring 51 lifts a stack of separator sheets 47 of, e.g., greaseproof paper against the mould. The uppermost sheet is drawn off the stack either by it adhering to the material in the mould or by providing the underside of the table 14, adjacent the mould, with adhesive tape or a knurled surface. When the mould reaches its left-hand position, a cam 29 is then in such a position that it allows a spring 56 to pull the ejector 41 down and eject the moulded material on to a casing 18. A notch 26a in the lever 26 provides a lost motion in the linkage for reciprocating the table, to allow time for the ejector 41 to be raised by the cam 29 before the table is moved to its righthand position. The sheets 47 are held in the stack by pins 62 and the uppermost sheet is always at the same level, as the sheets are continually pushed upwardly against the top of a yoke 53.

Title: Automatic regulator for fluid flow control
IPC: F16K15/00
Filed: 1964-04-03
Abstract: 1,049,509. Filling &c. tanks. ISHIKAWAJIMA-HARIMA JUKOGYO KABUSHIKI KAISHA. April 3, 1964 [Aug. 29, 1963], No. 13816/64. Heading B8T. [Also in Divisions F2 and G3] An automatic regulator for throttling a pipe connected to a tank in a system for pumping liquid into and out of the tank comprises throttling means in the form of a pivoted vane 3, which may or may not have an opening 4, the vane being opened when the liquid in the pipe flows in direction A, and closed when it flows in the other direction. In Fig. 2, with fluid flowing in the direction A, the vane 3 pivoted on an axle 2 opens away from the seat, final movement to a seat 9 being achieved by the flow acting upon a second flap 5 which is hinged at 6 and rests against a stop 7. A float 14 (Fig. 4) is positioned in the tank T, and rises with the tank water to cause tongs 18 to close, grip the end of a lock lever 10 attached to one end of the axle 2 and so hold the vane opened even when flow is in the direction B until the level in the tank falls below a predetermined minimum. The lock lever is then released and the vane is moved by the flow to the seat 8 when only a by-pass flow through opening 4 is permitted. A weight 11 attached to the axle holds the vane at a 45-degrees position (Fig. 2) when the tank is empty and only air is being pumped. Near the other end of the axle 2 is a diametrical hole which is in line with two holes in the surrounding body when the vane is in the 45-degrees position. The first hole is connected to a source of compressed air whilst the second hole is connected to a signal generator which effects the closing of a valve and the stopping of a pump in the pipe or signals an operator to do the same. The balance weight may be replaced by a spring. In another embodiment the throttling means is held open by a catch attached to a float, and closes the pipe completely when in its closed position, a pipe of smaller diameter receiving the remaining reduced outflow of liquid from the tank, and positioned between the throttling means and the valve in the pipe.

Abstract: 706,125. Reciprocating fluid-pressure engines. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 4, 1952 [June 14, 1951], No. 14083/51. Class 122 (2) In a reciprocating elastic fluid pressure engine comprising at least one working cylinder B<SP>1</SP> the working space of which communicates with a combined inlet and exhaust chamber B<SP>3</SP> through a combined inlet and exhaust passage B', the valve apparatus for controlling the flow of working fluid to and from the combined inlet and exhaust chamber B<SP>3</SP> comprises an inlet valve H of the seated type arranged to be lifted from its seat G<SP>5</SP> against the action of working fluid in the working fluid supply passage E' and controlling an inlet port G<SP>3</SP> at one end of the combined inlet and exhaust chamber B<SP>3</SP>, a pistontype exhaust valve J operating within a bore opening out of the other end of the combined inlet and exhaust chamber B<SP>3</SP> to open exhaust ports G<SP>7</SP> when it moves in a direction awny from the inlet valve H, and a part K projecting adjustably from the end of the piston valve J to lift the inlet valve H when the piston valve is nearing the end of its movement towards the inlet valve H. At approximately the top of each stroke of the working piston E the piston-valve J is raised by an eccentric L on the crankshaft C, and the part K, comprising a screw which may be screwed into or out of the piston-valve J to vary the period of opening of the inlet valve H, engages the latter and maintains it lifted for about 80 degrees of crankshaft rotation and then permits it to close. The piston-valve J is then urged to descend by a spring M and, at about the end of the downward stroke of the working piston E, it uncovers the exhaust ports G<SP>7</SP>. The valve J continues to move down for 40 to 45 degrees of crankshaft rotation during the beginning of the upward movement of the working piston E, and then moves upward with the working piston to close the ports G<SP>7</SP> near the end of the exhaust stroke. Valve J and working piston E then rise together so that the residual steam in the working cylinder is compressed to a pressure approximately equal to that in the inlet passage E' thus equalizing pressures on the inlet valve H when it is next opened. For part of its downward movement the valve J is subject to working pressure and thus acts as a subsidiary piston on its eccentric L. In Fig. 2 (not shown) the steam passage E' is coaxial with the combined inlet and exhaust chamber B<SP>3</SP> and the inlet valve is in the form of a ball co-operating with a conical seating. The spring H' and sleeve G are omitted. In Fig. 3 (not shown), the passage E' and sleeve G are provided as before but the inlet valve comprises a valve head in the form of a disc having a frusto-conical seating surface and a stem projecting from the head and sliding within the inlet passage below the valve and formed so as to permit the free flow of fluid between itself and the inlet passage wall.

Filed: 1966-03-30
Abstract: 1,137,763. Piezoelectric transducers. GENERAL DYNAMICS CORP. 30 March, 1966 [30 April, 1965], No. 14188/66. Heading H4J. Piezoelectric transducer, particularly for use under water, comprises one or two piezoelectric ceramic discs e.g. 21 and 22, Fig. 1, cemented into recesses in a diaphragm plate 23, e.g. of steel aluminium or phosphor bronze, which is fixed at its peripheral edge 36 in a housing 14, 15. The central portion of the diaphragm plate is pivoted relative its rim portion 36 by the hinge formed between the annular recesses 38, 39 which allows the central portion of the plate to dish either under acoustic pressure incident on the transducer or in response to signal voltages applied to the piezoelectric elements 21, 22, causing them to differentially expand and contract radially. The arrangement is said to provide good coupling between the diaphragm and the elements since the radial expansion and contraction of the elements is communicated to the diaphragm, or vice versa, not only over the adjoining faces of the elements and diaphragm, but also by the attachment of the edges of the elements to the annular ridges 7 and 8. The elements may be of barium titanate or solid solution of lead zirconate and lead titanate. The housing is sealed by a rubber member 48 which forms an acoustic window for the transducer, and the housing may contain an amplifier in space 19. In alternative forms only one element may be used attached to one side of the diaphragm plate, Fig. 4 (not shown), or the diaphragm plate may be rectangular with a number of elements mounted in a channel in its surface, Fig. 5 (not shown), the diaphragm bowing in one plane only under the influence of driving forces. It is also stated that the transducer element may be magnetostrictive.

Title: Method of forming strongly adherent metallic compound films by glow discharge and articles resulting therefrom
IPC: C03C17/36
Filed: 1945-06-06
Abstract: In a method of adhering a metallic coating to a vitreous silicious support material the support is coated by thermial evaporation in a vacuum with an intermediate layer which is oxidized by glow discharge in an oxygen containing atmosphere and the metallic coating deposited on the oxidized layer.  The intermediate layer may be a metal or a salt of a metal, e.g. sulphide, phosphide, which may be selenide, oxidized by glow discharge either in oxygen or in an oxygen containing gas at a pressure of 1 to .01 mm. of mercury.  As an example lead or lead sulphide may be deposited on glass by evaporation in a vacuum 45, the layer formed may then be oxidized by glow discharge, after the admission of an oxygen containing gas, to lead oxide or lead sulphate and a coating of silver deposited on the oxidized layer by thermal, evaporation, spluttering or deposition from a silver compound.  The surface of the silver layer may also be partially oxidized to form a coating of silver oxide.  Specifications 605,871, 605,873, [Group III], 606,874 and 605,889 are referred to. The Specification as open to inspection under Sect. 91 comprises also the use of spluttering as the method of deposition, and the use of a tungstate as the intermediate layer and the use of a metal as the base.  This subject-matter does not appear in the Specification as accepted.
