Patent GB-2117907-A (GB)
Title: Indicator instruments
Inventor: JONES MAURICE SIDNEY
IPC: G01P5/175
Filed: 1983-03-31
Abstract: A Mach/airspeed indicator instrument has two pressure capsules 13 and 11 each of which have a finger 40 and 30 projecting from one face coupled to a respective arm 43 and 33 that extends radially from respective shafts 50 and 34, so that displacement of a finger causes rotation of the respective shaft about its axis. Rotation of shaft 50 causes rotation of a Mach scale plate 4 whereas rotation of shaft 34 causes rotation of an airspeed pointer 10. The rear end 64 of the Mach shaft 50 is rotatably mounted at one end of a radially-extending lever 54 that is pivotally mounted close to its other end. The airspeed shaft 34 is coupled with the Mach shaft 50 by means of a link 60 that extends between a plate 61 fixed to the airspeed shaft and the lever 54. Rotation of the airspeed shaft 34 causes rotation of the lever 54 and lateral displacement the Mach shaft 50 about a pivot point at the end of the finger 40. This produces a rotational component about the axis of the Mach shaft that ensures linear displacement of the Mach scale plate 4. <IMAGE>

Title: Apparatus for controlling the flow of gas
Inventor: RODGER KEITH PHILIP
IPC: F16K31/06
Filed: 1983-06-27
Abstract: A gas valve comprises a resilient valve member (14) which co-operates with a fixed annular valve seat. The valve member is mounted on a flexible and resilient arm (13) which is cantilevered at its outer end and biases the valve member to a closed position. The arm can be attracted by an electromagnet (15) so as to lift the valve member from its seat. The extent to which the valve opens varies with the current through the eiectromagnet. The electromagnet is housed, within a ferromagnetic body (2), and an axial tube (4) forming an integral part of the body constitutes a core for the electromagnet and gas inlet. The valve seat is formed around a gas outlet and constitutes part of a non-ferromagnetic cap (3) screwed onto the body. The resilient arm constitutes part of an apertured disk (12) of which a marginal part is trapped between the cap and the body. <IMAGE>

Patent GB-2135837-A (GB)
Title: Power converting apparatus
Inventor: ANDO TAKEKI
IPC: H02M7/155
Filed: 1984-02-08
Abstract: The apparatus includes elements, e.g. GTO's (UGTO, VGTO, WGTO) connected to the positive arms respectively of a full-wave controlled-rectifier bridge circuit rectifying the output of an AC power source (Ea). The current flowing through a load (L) is circulated through a circulating loop when any one of the switching elements is turned off. A plurality of series circuits each including a capacitor (Cf) and a reactor (LF) connected in series is connected across the power supply lines of the AC power source, so that an overvoltage induced in the power source part when any one of the switching elements is turned off can be absorbed by the associated capacitor, and a discharge current discharged with a sharp rise from the capacitor to flow through the circulating loop when the switching element is then turned on is suppressed by the associated reactor. In other embodiments the apparatus chops rectified AC, Fig. 11, or inverts rectified AC, Fig. 12. In each of these latter embodiments, a single series circuit of a capacitor and a reactor is connected across the input power supply lines to the chopper switching element and inverter switching elements. The apparatus may be used in a rail vehicle, Fig. 13, or an elevator, Fig. 14. <IMAGE>
