Title: Improvements in or relating to reversing mechanisms for the valves of gas-meters
IPC: G01F3/22
Filed: 1931-01-23
Abstract: 371,058. Gas meters. PINTSCH AKT.- GES., J., 71, Andreasstrasse, Berlin. Jan. 23, 1931, No. 2329. Convention date, July 26, 1930. [Class 54.] A reversing mechanism for the valves of a gas meter comprises a lever U which carries a sleeve 33 encircling a compression spring KF arranged between the valve-operating levers 23, 24 and is snapped over into one of its two end positions as the lever F, which is oscillated by the gas-meter diaphragm and is connected to the lever U by a link 36 and tension spring UF, passes through a position in alignment with the lever U. The consequent distortion of the spring KF by the sleeve 33 causes levers 23, 24 to be operated to reverse the valves V1, V2 controlling the gas flow to the measuring chambers. The valves in the positions shown are pressed on their seatings by the spring KF augmented by the tension of the spring UF which is nearly relaxed immediately after reversal of the valves. As the lever F is moved the spring UF is tensioned and the friction between the spindle of the lever F and the bush of the lever U tends to increase the torque on the sleeve 33. The spring KF may be replaced by two separate springs 50, 53, Fig. 12, preferably oppositely wound, the outer spring exerting the axial pressure and the inner one, which has some play in the axial direction, taking the bending strain.

Abstract: 1294133 Reciprocating pumps for liquids and gases UNITED KINGDOM ATOMIC ENERGY AUTHORITY 13 Jan 1970 [15 Jan 1969] 2509/69 Headings F1A and F1N In a pump for injecting amounts of radioactive fluid into a fluid stream, the pump piston 20 is actuated by a spring-loaded plunger 27. Piston 20 is mounted in a cylinder 14 in block 10 and is biased outwardly by a spring 23; escape of radio-active fluid is prevented by a phosphorbronze bellows 22 between block 10 and a flange 21 on the piston. Plunger 27 passes through a plate 25 and is screwed through a disc 33, and is inwardly biased by a spring 31 between plate 25 and a flange 28 on the plunger. To operate the pump, disc 33 is rotated until plunger 27 is raised so that a pin 38 engages a slot 39 in the plunger; this compresses spring 31, the compression may be varied by axial adjustment of plate 25, and piston 20 moves under the action of spring 23 allowing the cylinder to be filled with tracer fluid from the reservoir 42. The disc is then further rotated to determine the stroke of the piston. On releasing pin 38 spring 31 reasserts itself and the piston drives fluid from the cylinder through a one way valve 16 into a fluid stream in conduit 17.

Title: Electronic material
Inventor: DAHLBERG REINHARD
IPC: H01B1/00
Filed: 1968-01-17
Abstract: 1,216,001. Semi-conductor devices. R. DAHLBERG. 17 Jan., 1968 [17 Jan., 1967], No. 2513/68. Heading H1K. A material primarily for use in thermoelectric applications consists of conductive layers alternately of positive and negative thermoelectric power each thinner than the mean free path of electrical charge carriers in the layer. The layers may be of metal, metallically conductive oxides, or semi-conductors. Suitable conductive materials are the oxides, nitrides and carbides of metals from the group chromium, titanium, iron, indium, manganese, niobium, vanadium, tungsten, molybdenum, uranium, tantalum, zirconium, boron; borides and silicides; germanium, silicon carbide, A III  B v , A II  B IV , and A I  B VII  compounds and P and N doped organic semi-conductors. The material is made by pressing or rolling a laminated body constructed of metal foils, or by electrolytic, pyrolytic, vapour or ion beam deposition or cathode sputtering. Deposition is preferably made on a cooled planar substrate which is rotated in front of two vapour sources offset from the axis of rotation to afford easy control of the layer thickness. The materials are said to exhibit photoconductive and photovoltaic effects, superconductivity, variation of resistivity with electric and magnetic fields applied perpendicular or parallel to the layers, to be useful in rectifiers, capacitors and oscillation generators and to exhibit high heat transfer characteristics parallel to the layers. Typical materials consist of an alternating sequence of (1) 500  antimony and 1000  bismuth layers; (2) 10  iron and nickel layers; (3) 10  gold and goldpalladium layers; (4) caesium and platinum layers. In a typical thermocouple the two limbs joined by a metal bridge consist of such material, the number of layers in each limb being odd and such that the two layers adjacent the bridge are thermoelectrically P and N respectively.

Title: Connecting and disconnecting system for switching equipment
IPC: H04Q3/00
Filed: 1969-01-16
Abstract: 1,210,792. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 16 Jan., 1969 [18 Jan., 1968], No. 2560/69. Heading H4K. In an exchange having a switching network consisting of mechanically latched cross-bars, the release of operated cross-points is effected just prior to the setting up of a new connection and not immediately on termination of the connection to which they relate. As shown, looping of a caller's line lg<SP>1</SP> is detected in his line circuit JA1 and the marker MQ connects it via singlestage cross-bar switch CCA to the inlet of oneway feedbridge AL1 if this is free. It should be noted that the feedbridges are one-way, only in respect of call-setting and not in respect of speech transmission and moreover, each group of subscribers may have access to more than one feedbridge via their single switch. The feedbridge seizes a free register EN which reverts dial tone and then accepts dialled digits from the caller. The identity of the called party, e.g. lgm, is passed to the marker and stored on a relay contact tree (Fig. 2, not shown). A relay sequence switch is effective thereafter to successively transmit disconnect signals to the vertical magnets of column 1 in switches CCA and CCC whereby any actuated cross-points in these columns are released. The sequence switch then applies signals to the vertical magnet of column 1 and to the horizontal magnet of row 1 in switch CCB whereby already operated crosspoints, if any, in the column are released and, virtually simultaneously therewith, the required cross-point is closed so as to connect the called line to the outlet s of the feedbridge. The register indicates ringing and then withdraws followed by the marker.

Filed: 1954-01-28
Abstract: 748,742. Drilling. BURG, F. G. Jan. 28, 1954 [May 11, 1953], No. 2610/54. Class 83 (3). A feed-control system for machine tools comprises a head 3 having a number of tool holders which can be brought into action successively, a fluid-pressure mechanism 21 for feeding the head towards the work and means A for pre-selecting the rate of supply of fluid to the mechanism for each position of the head. Drilling, reaming or tapping tools are each rotated in the working position at a speed preselected by a mechanism 10 indexed together with the turret by gearing 30, 32. As the turret 3 is indexed, gearing 30, 31 also rotates a valve-plate 33 having a port 34 communicating successively with valves 54, pre-set according to eacli feed-speed required. Pressure-fluid thus passes from a pump P through line 60, chamber 50, port 34, the appropriate valve port 35, chamber 52 and line 53. The direction of movement of the piston 26, which feeds the head, is determined by a valve 62 positioned by solenoids 65, 66. The solenoid 65 is actuated by a switch 77 which is responsive to pressure build-up at the end of a feed-stroke. The end of such a stroke is determined by one of six adjustable dogs 70 which successively engage a bar 75. At the upper limit of a withdrawal movement, dogs on a disc 80<SP>1</SP> rotated by the worm 30 actuate switches 79 to reverse the valve 62. To obtain fast approach and retract movements a by-pass valve 81 is actuated by a solenoid 82 controlled by dogs 84 engaging switches 85, 86. The dogs 70, 84 are carried on a drum 11 supported by the piston 26 and indexed with the turret. A pointer 45 indicates which valve 54 is in operation. Specification 748,747, [Group XXIX], is referred to.

Abstract: 611,528. Dynamometers. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., BAILEY, W., and ROY, J. Jan. 28, 1946, No. 2791. [Class 106 (ii)] The power output of a gas turbine engine 1, or the turbine rotor thereof, is measured by coupling it, preferably through a transmission dynamometer 5, to a rotary compressor 4 capable of absorbing the full output of the turbine and providing means whereby even when the turbine is not delivering maximum output the mass air flow through the compressor is substantially unaltered. The compressor 4 is coupled to a second turbine 6 which augments the output of the test turbine 1 to drive the compressor to maintain the even mass air flow. The delivery from the compressor 4 enters a chamber 7 from which it may exhaust through a valve 10 to atmosphere, or through the second turbine 6, annular duct 8 and throttle valve 9 to atmosphere. To absorb the whole power of turbine 1 the valve 9 is closed and valve 10 opened, and for lower outputs the valve 9 is opened and valve 10 partly closed. A heated duct 11 may connect the compressor outlet with the air intake 2 of the turbine 1. To enable the turbine 6 to deliver a greater amount of power to the compressor 4, provision may be made for burning fuel in the chamber 7. The valve 9 may be arranged between the compressor and turbine 6. The casing of the compressor may be mounted to rock about its horizontal axis to enable torque input to be measured.
