Title: Preparation of silicon carbide fibers
Inventor: WEI GEORGE CHIA-TSING
IPC: C01B31/36
Filed: 1984-09-26
Abstract: Silicon carbide fibers suitable for use in the fabrication of dense, high-strength, high-toughness SiC composites or as thermal insulating materials in oxidizing environments are fabricated by a method wherein a mixture of short-length rayon fibers and colloidal silica is homogenized in a water slurry.

Patent GB-2160107-A (GB)
Title: Electrode plate for an ecg electrode
Inventor: LUNDBACK STIG
IPC: A61B5/296
Filed: 1985-08-12
Abstract: The invention relates to an electrode intended, for example, for electrocardiogram examinations, and capable of being held in position by suction. Vacuum conditions are created through a hose or tube (8), through which a measuring conductor (7) is drawn. The electrode comprises an inflexible backpiece (3), an intermediate component (2) made of an elastomeric material, and an electrode plate (1), preferably made of a silver-coated plastics. The intermediate component (2) includes a relatively inflexible sealing ring (9) which, in the operative state of the electrode, supports against the skin of a patient via a sealing lip (13) and against the opposing side of the backpiece (3). The electrode plate (1) is firmly connected to the backpiece, while the sealing ring carried by the intermediate component (2) is movable and can be readily sprung away from the backpiece (via resilient means 17). When no load is exerted on the lip-side of the ring and the ring is thus urged outwardly, a vacuum valve is closed automatically through the intermediate component (2), and is re-opened when the electrode is pressed against the surface of the skin, whereupon the electrode is held firmly by suction.

Title: Measuring displacement of elongate elements, particularly wire ropes
Inventor: BIRD RONALD ERNEST
IPC: G01D5/14
Filed: 1986-11-11
Abstract: A wire rope 10 is an example of an element whose ferromagnetic properties vary periodically along its length, owing to its coiled construction. If displaced through a magnetic field (produced by a magnet 14), the magnetic reluctance adjacent it is varied periodically. A small detector (suitably a Hall effect device 16) located close to the rope 10 provides a correspondingly varying electrical signal which can be processed to provide a series of pulses that can be stored and used to provide a display related to the displacement rate. Two detectors may be spaced apart along the length of the rope in order to obtain an indication of the displacement direction. <IMAGE>

Title: Collapsible steering column
Inventor: SUZUKI HIROSHI
IPC: B62D1/16
Filed: 1990-06-01
Abstract: A steering column tube for a motor vehicle capable of obtaining a superior energy absorption power in a car crash has energy absorbing plates 14 between a first end part of a first column tube member 12 and a second end part of a second column tube member 13. In each of the energy absorbing plates, a buckling adjusting part 15 is provided at a part of the inner-side piece of the energy absorbing plate so as to swell toward an outer-side piece 14c of the energy absorbing plate. For this reason, when a car crash gives an impact force to the first or second column tube member, the successive buckling of the energy absorbing plates is performed instantly, thereby enabling the absorbing amount of energy to be maximized under the limited load and displacement amount. <IMAGE>

IPC: B23F17/00
Filed: 1990-12-12
Abstract: A blank from small batches of toothed gears with fixed dimensions apart from their outside diameters is secured on the work-table of a hobbing machine, its periphery is milled to the required size (and shape in planes containing its axis) by a cutter 20 secured on the hob-spindle of the machine, and teeth are then cut in its periphery without removing it from the work-table by a hobbing cutter 22 secured on the hob-spindle.
