Patent GB-2129511-A (GB)
Title: Shims for disc brake pads
Inventor: ROWBOTTOM BERNARD ALBAN
IPC: F16D65/097
Filed: 1983-11-01
Abstract: A shim includes a shim pad 4 of heat resistant composite material and a metal clip 3 which overlies the shim pad, locates it in position, and clips into a brake piston 9 in a calliper. The metal clips 3 preferably protects the shim pad 4 from direct contact with the piston and the metal clip preferably does not bridge over the shim pad and all the pressure from the piston is transmitted through the shim pad. The heat-resistant composite material can be used as an insulating material to form a barrier to reduce conduction of heat from the brake pad into the piston in a disc brake assembly; the material may comprise glass fibres; mineral fibres; aromatic polyamide fibres; asbestos fibre material with binder etc. As shown, clip 3 has three clip members 6,7 (8) fitting inside piston 9, a retaining clip 5 around edge of clip 3 locating pad 4. In the embodiment of Figures 4-6, a recess (14) acts as locating means for shim pad and the metal clip is extended to the side edges of the brake pad back-plate. An annular shim pad to match the piston shape could be used. <IMAGE>

Title: Dual-gate field-effect transistor
Inventor: SECHI FRANCO NICOLA
IPC: H01L23/12
Filed: 1983-11-23
Abstract: An FET pellet 10 is combined with a special carrier (70, Figure 7) having a source pad 76, a drain pad 74, and first and second gate pads 78, 80 and another pad 82 to create a dual-gate FET with relatively high power handling capabilities; when conventionally combined with a carrier which contains source (S), gate (G) and drain (D) electrodes the combination provides a single- gate power FET. In the dual-gate FET some of the conventionally drain electrodes (D) are connected to the source pad 76 as source electrodes S1, some of the gate electrodes are connected to the first gate pad 78 as first gate G1 and some of the gate electrodes are connected to the second gate page 80 as second gates G2. Some conventionally source electrodes (S) are connected together by a pad 82 as interconnected drain D1 and source S2 electrodes. Some conventionally source electrodes (S) retain the characteristics of source electrodes S2 and other conventionally source electrodes (S) have the characteristics of drain electrodes D1. <IMAGE>

Title: Photographic flash apparatus
Inventor: TAKEMATSU YOSHIYUKI
IPC: H05B41/32
Filed: 1984-01-13
Abstract: Photographic flash apparatus including a main discharge capacitor 9 and means for dissipating the charge thereon when non-flash photography is required, further includes blocking means for stopping the charge dissipation when the capacitor voltage has dropped below a predetermined level, whereby energy is saved and less time is required to recharge capacitor 9 when flash photography is next required. When a switch is moved to a non-operative position 2a, capacitor 9 and a trigger capacitor 10 are discharged via a neon lamp 20 until the capacitor voltage falls below the operating voltage of lamp 20. The lamp 20 is a lower voltage type than a neon lamp 16 used to trigger on an LED 18 for indicating that capacitor 9 has charged to a required level. A zener diode (22), (Figures 3, 6) may be used instead of lamp 20. Other embodiments (Figures 8, 10) have a zener (74) to stop a DC-DC converter when the main capacitor (59) voltage has reached the required level, a neon (66) or a flickering LED (68) being used to indicate the latter. In further embodiments the discharge circuit is permanently connected across the main capacitor (Figures 9, 12). <IMAGE>

Title: A method of, and tools for, remotely positioning and attaching a strain gauge
Inventor: ASHBY ROBIN
IPC: B24B23/06
Filed: 1984-02-21
Abstract: A method of, and tools for, remotely positioning and attaching a strain gauge on a buried gas or water pipe. A limited "key-hole" excavation is made and, by using special tools, three gauges, e.g. VW strain gauges, may be positioned at spaced locations around the pipe, one on the crown of the pipe and one on each side surface. A number of tools are described of which the most important is a tool (Figure 8A) for holding and positioning the gauge. The tool has an elongated frame 35 and a pivoted U-shaped frame 41 which carries a jig 31 on which the strain gauge is mounted. By rotating knob 42 the frame 41, together with jig 31 and the strain gauge may be moved towards and away from the pipe 39 to which the gauge is to be fixed. Once the gauge is bonded or fixed on the pipe the jig 31 is pulled clear of the gauge by the frame 41 and the tool is then removed. A portable belt grinder is also disclosed (Figures 2A,B,C,), driven by an hydraulic or pneumatic motor, for cleaning the gas or water pipe prior to the application of the strain gauge. <IMAGE>
