Title: Suspension for two-wheeled vehicle
IPC: F16F3/04
Filed: 1972-08-07
Abstract: 1401988 Combined spring and damper units KAYABA KOGYO KK 7 Aug 1972 [10 Aug 1971] 36704/72 Heading F2S [Also in Division B7] A combined spring and damper unit acting as a motorcycle suspension front fork (Fig. 2, not shown), or rear unit comprises a telescopic hydraulic damper 121, two helical springs 144, 145 disposed in series (inside Fig. 2, or outside the damper) with a spacer 146 between them, a stop 147 on the damper 121 which engages the spacer 146 to limit its movement, and adjusting means 127, 133, at that end of one of the springs remote from the spacer 146 to adjust the preload on that spring. In Fig. 2, the helical springs are housed inside the oil-containing telescopic front fork which constitutes the damper. In both Fig. 2 and Fig. 4 the adjustment means is a cam. The position of the stop 147 is also adjustable. The springs 144, 145 are so selected that the load required to completely compress the spring 144 is greater than that required to completely compress the spring 145. The spring 145 is then preloaded by means of the cam 127, 133 and/of the adjustable stop 147. Under load, there are three stages. Until the applied load reaches the preload given to the spring 145 the spacer 146 is held against the step 147, and only the spring 144 is compressed. At applied loads above the preload of spring 145, both springs are compressed, until the load at which the spring 145 is fully compressed is reached. Above this load the spring 144 is again compressed alone. The spring 145 may instead be the stiffer spring. Load-deflection graphs for various combinations of springs, preloads, and position of the stop 147 are depicted in Figs. 5-10 (not shown).

Title: Improvements relating to electrical resistance devices with a non-linear voltage current characteristic
IPC: H01C7/118
Filed: 1955-12-29
Abstract: 799,687. Semi-conductor devices. GENERAL ELECTRIC CO. Dec. 29, 1955 [Jan. 21, 1955], No. 37270/55. Drawings to Specification. Class 37. A resistor with a non-linear voltage-current characteristic comprises a base member with a coating comprising finely-divided silicon carbide and a binder consisting of clay, porcelain or glass fused to the base. The coating material may include additional conductive materials such as graphite, iron, tungsten, nickel and silicon. An insulating base member comprising aluminium silicate porcelain and talc, dry pressed to form a bar, may be used. This has a coefficient of expansion and shrinkage similar to the coating which may therefore be applied in suspension by spraying, pouring, dipping, brushing or rolling to the unfired base which is then fired to vitrify the base and render the coating adherent. Firing, preferably in an oxidizing atmosphere, is at 700-800‹ C. for a few minutes where a glass binder is used, or at 1200-1300‹ C. for 6 to 7 hours in the case of a porcelain or clay binder. If an alumina base is used, however, the base must be vitrified before the coating is applied. Bronze or copper electrodes may be sprayed or evaporated on the base adjacent the coating or may overlap the coating. Alternatively foil electrodes may be used. The coating may be in the form of a zig-zag on a flat plate, or a spiral on a cylinder or tube. Low capacitance is obtained by using a thin coating. As a further alternative for low resistance devices a disc-shaped conducting base, e.g. of steel, copper, bronze or aluminium is provided with a sprayed-on layer comprising a glass binder containing a temporary binder such as polyvinyl alcohol, or an alkyd resin which decomposes during firing in a reducing atmosphere and an electrode layer on top of this. Flexible base members may also be used. A single base member may be provided with a plurality of coatings of different characteristics, the electrode connections to which may be arranged in a number of ways to give different parallel or series combinations. Specific compositions of the layer and insulating base materials are described in the Specification.
