Abstract: 112,024. Renard, C. F. Dec. 12, 1916, [Convention date]. Spring wheels with continuous outer rigid ring and helical springs.-The hub member of a wheel comprises two concentric cylindrical rims a, b, Fig. 3, which are rigidly connected and serve as guides for sliding blocks g, g<1>, the ends of which have right-angled notches engaging rollers h on pins h<1> rigid with the felloe of the wheel. Circumferential springs engage projections on the guide blocks and press them against the rollers. in the wheel shown in Fig. 3, the springs k are mounted on curved guide-tubes m, and are clamped at the middle to rods c which connect the rims a, b. The wheel shown in Fig. 10 has two rings o, p, in place of the separate pairs of sliding blocks. Each ring has a series of right angled notches g, g<1>, corresponding to one set of blocks, and the springs k press against bosses on the two rings and tend to move the rings in opposite directions circumferentially. Any displacement of the hub and felloe members is thus resisted equally by each of the springs. The displacement is limited by stops r, r<1> engaging projections q<3> on the felloe. Normally, the rollers occupy the angle of each notch, but any eccentricity of the hub and felloe causes them to ride up the inclined edges and causes the sliding blocks to move circumferentially.

Abstract: 1424025 Measuring shocks electrically ASAHI KASEI KOGYO KK 18 April 1973 [24 April 1972 29 May 1972 30 Oct 1972] 18640/73 Heading G1N [Also in Divisions F2 and G3]  Apparatus for measuring mechanical shocks is exemplified by the embodiment of Figs. 1 and 3 wherein a block 1 has a closed fluid path made up of horizontal channels 2, 5 and vertical channels 3, 4 so that a shock force 20 displaces mercury 6 in the channel 2 between the poles 8a, 8b of a U- shaped magnet 8, 9 and generates a voltage between electrodes 10, 11 whose amplitude is indicative of the rate of flow of mercury and hence proportional to the magnitude of the shock. The flow-path contains restrictions 16, 17 which act as a high frequency filter to reduce noise in the output signal, and to produce a sharp cut off in the electrical signal. In an embodiment according to the invention, the flow-path contains a threshold device, e.g. a spring-biased valve 24 Fig. 6 which closes the connection between channels 2 and 4 to shocks below an adjustable value. Other mechanical threshold devices are described such as gravity devices, a float member, magnetic members, a flexible or rupturable membrane, or a porous  member utilizing the surface tension of the mercury 6 to prevent flow with small shocks. Facilities are provided to prevent the accumulation of mercury 6 beyond the threshold device. To sense shocks in a range of directions a plurality of vertical channels 3 are provided over an angular range, joined to the right hand part of the apparatus shown in Fig. 1 by parallel horizontal branches 2, 5, the branches 2 1 -2 8  Fig. 17 containing convolutions or other means which restrict fluid-flow from the centre 60 to the outer connections 65 but allow free liquid flow in the other direction. The liquid paths may contain different fluid-flow restrictions to produce different desired sensitivities to shock forces in different directions. An electrode may be assembled in each corner of the lid of block 1 to be selectively contacted by the mercury 6 when the unit is inclined, to indicate the direction of the inclination. The sensor may be mounted on a vehicle and used to inflate a safety bag when the vehicle is involved in a collision. The electrical signal voltage is fed through a threshold device and amplified to fire a thyristor which energizes an ignition charge to release gas to the safety bag.

Filed: 1949-07-18
Abstract: 662,501. Tappets. SCOTT, W. A. June 5, 1950 [July 18, 1949], No. 18821/49. Class 80 (iii) A tappet, particularly for the valve gear of an internal combustion engine, automatically compensates for changes in length due to wear or temperature variations. The tappet comprises two relatively slidable parts a, b pressed apart by a spring e and held by a retaining ring f engaging a circumferential groove g. The two parts are bevelled at different angles to provide a tapering annular groove d containing a number of wedging steel balls h whose position in the groove determines the tappet length. When the rod j has fully opened the valve the load on the balls is momentarily released and due to momentum and vibration they move to an outer position in which they remain until the valve contacts its seat in closing, when the spring e expands the tappet and allows the balls to return under gravity to the appropriate inner wedging position giving an overall tappet length compensating for any changes in actual length of the operating mechanism. The retaining ring f may be replaced by a sleeve containing the parts a, b, and an adjustable screw may be provided on one of the parts.

Abstract: 1,268,185. Welding by pressure. BURNLEY ENG., PRODUCTS Ltd. 14 April, 1969 [23 April, 1968], No. 19059/68. Heading B3R. In resistance spot welding two members which do not conform sufficiently for satisfactory welding between conventional rigid electrodes, an electrode in pliable condition is employed. A metal honeycomb seal 10 Fig. 1 is applied to a metallic ring 11, an electrode 22 is applied to the ring 11 remote from the honeycomb seal and an electrode 14 is applied to the seal, the electrode 14 comprising a metallic holder 15 containing a number of copper strands 16. The strands 16 deform under pressure and flatten high spots on the seal without damage thereto and welds are made between the faces of the cells of the seal and the ring 11. A similar deformable electrode may also be applied to a backing ring having an irregular face remote from the honeycomb seal. In a modification a braided strip or sheet of electrically conductive metal or a braided copper tape may be employed to engage the honeycomb seal and is pressed by a relatively non-deformable electrode. In a further embodiment the deformable electrode comprises a braided copper sheet 33 Fig. 7 or thin copper sheet mounted on a hollow fluid impermeable backing 74, e.g. of leather or thermoplastics, containing a pressure medium e.g. air, water or oil. The ends of the sheet are secured to a metal holder 37 through which current is supplied and pressure applied. The deformable electrode of Fig. 7 may be used possibly with a similar electrode to weld a metallic honeycomb core between two metallic sheets to form an acoustic panel having e.g. a double curvature. Spot welds are produced by the apparatus of the invention at closely spaced positions. If a honeycomb seal has its cells at an angle to the surface it engages, that surface may be knurled or grooved to prevent slipping under electrode pressure.
