Patent GB-2093997-A (GB)
Title: Flowmeter
IPC: G01F1/32
Filed: 1981-03-03
Abstract: A flowmeter for determining the volume of fluid flowing along a channel 2 includes a bluff body 4 mounted in the channel so as to induce the formation of vortices in the fluid. A pressure sensor 3 is positioned in the channel downstream of the bluff body so as to detect the pressure variations associated with each vortex. The pressure sensor comprises a light transmissive body whose optical birefringence properties are pressure dependent. A remote light source and photodetector are coupled to the body by optical fibres and the variation in light level received at the photodetector is representative of the fluid flow. The pressure sensor can be completely passive so that the flowmeter can be used with corrosive or inflammable fluids. <IMAGE>

Patent GB-2088794-A (GB)
Title: Laser Doppler Velocimetry System to Control Aircraft Wheel Speed
IPC: B64C25/40
Filed: 1981-12-01
Abstract: A laser doppler velocimetry (LDV) system on board an aircraft 1 is used to match the rotational speed of the aircraft wheels to the ground speed of the aircraft. The laser's output beam is caused to illuminate the ground in front of the aircraft on its landing approach. Laser radiation reflected from the ground is detected and processed to determine its doppler shift and hence ground speed. The aircraft wheels are spun e.g. by motors to match the ground speed. A laser beam defector may direct the laser beam onto the ground and the wheels in turn to measure both ground and wheel spin (Fig. 5). <IMAGE>

Title: Multi-level metallizatien structure for semiconductor device and method of making same
Inventor: FISHER ALBERT WAYNE
IPC: H01L21/768
Filed: 1984-01-26
Abstract: A semiconductor device (10) having a multi-level metallization structure wherein the first level (26) is of aluminium containing silicon, and the second level (34) is either aluminium or aluminium containing silicon in an amount less than that contained in the first level (26). The two levels (26, 34), where they contact each other, are sintered together, with some of the silicon from the first level (26) being diffused into the second level (34) so that the second level (34) has a region (34a), adjacent the junction between the two levels (26, 34), which has a higher content of silicon than the remaining portion of the second level (34). When making the device (10), the surface of the first level (26), where it is to be joined with the second level (34), is etched to remove some of the aluminium, but not the silicon, which roughens this surface. The second level (34) is applied on this roughened surface, and the device (10) is heated to sinter the two levels (26, 34) together and diffuse the silicon into the second level (34). <IMAGE>

Title: Cable termination to connector allowing relative movement
Inventor: THOMAS DAVID ELLIS
IPC: H01R13/58
Filed: 1984-06-27
Abstract: In an electrical connector a first tube 10 is secured to a mating portion 11 by means of a retaining nut 12 gripping a flanged portion 14 against a complementary part 15 of the mating portion 11. A second tube 16 is secured to a cable 17 through the agency of a ferrule 18. Cable conductors 19 are brought to terminations 100 within the second tube 16 to which flexible conductors 101 are also attached to form a path onward to mating portion 11.
