Title: Improvements in or relating to shock absorbers
IPC: F16F9/48
Filed: 1961-02-21
Abstract: 898,118. Shock absorbers. FORD MOTOR CO. Ltd. Feb. 21, 1961 [March 10, 1960], No. 6291/61. Class 108(3). A shock absorber of the kind having an inner pressure tube 12 and an outer reservoir tube 14 and damping mechanism including a foot valve 16 and a valved piston assembly 30 is characterized in that pairs of compression and rebound orifices 50, 52, positioned alternately 90 degrees apart in the piston assembly 30, are controlled respectively by poppet valves 54, 56 which are carried at the ends of the arms of a star-shaped spring 58 which is appropriately distorted to urge the valves 54, 56 towards their closed positions with a force which is modified by the action of a coil spring 64. The effect of the latter is to increase the damping of the unit approximately in proportion to the displacement of the piston 38 from its normal midway position. The piston rod 24, which extends through a closure member 18, a rubber seal 26 and an interposing spring 28, has an axial bore 40 in that end which screws into the piston element 38, the bore 40 communicating with diametral passages 42 which lead to a space between a disc 44 .and an inverted cup-shaped member 48 both of which are secured within the piston element 38 during assemblyof the latter to the piston rod 24. The spring 58, loosely arranged around the piston rod 24, has a circular groove 70 which engages the lower end of the spring 64 the upper end of which is secured by a retainer 66 to the closure member 18. In use, as the piston 38 moves upwardly or downwardly, the opening of the respective pairs of poppet valves 54 or 56 is made progressively harder as the spring 64 is correspondingly stretched or compressed.

Title: Surface Coating Process
IPC: C04B41/52
Filed: 1967-02-15
Abstract: 1,176,755. Coatings. H. DOUBRAVA and L. DOUBRAVA. 15 Feb., 1967 [16 Feb., 1966], No. 7309/67. Heading B2K. Glaze, enamel or paint coatings of silicate or silicate-containing substances are formed on products which contain or consist of calcareous cement or clay by providing the products with a layer of alkali metal silicate, drying, and subjecting the coated product to the action of a hot salt solution, which contains an alkaline earth metal salt or a mixture of alkaline earth metal salts and, if desired, one or more alkali metal salts, thereby forming an alkaline earth hydroxide by reaction of alkaline earth metal salt with alkali metal hydroxide derived from the applied alkali metal silicate leaving silica in the layer in place of the alkali silicate, and treating the coated product with hot water, or steam in an autoclave under superatmospheric pressure. For the formation of enamel or paint coatings having a high content of auxiliaries, the alkali silicate layer has a high content of auxiliaries e.g. pigments and/or others, is coated, after drying, with an alkali metal silicate layer, which is free of auxiliaries or has a relatively low content of auxiliaries, and is then treated with the hot salt solution, and the resulting coated product treated in the autoclave. The glaze, enamel or paint coating contains silica, and is characterised in that the silicon atoms of the silica in the coating are randomly and completely connected by oxygen bridge linkages to form a three-dimensional lattice of SiO 4  tetrahedrons, the coating is free of amorphous silica and of alkali, and the content of auxiliaries at least in a surface layer of the coating is so low that the coating resists boiling water. The silica may have a density of approximately 2. The water is controlled for a low calcium content and preferably for an absence of calcium, during the treatment with hot water or steam. A starting product containing calcareous cement may be pickled with a dilute acid before the alkali metal silicate layer is applied. Sodium silicates may be used in the composition range from Na 2 O: 2SiO 2  to Na 2 O:4SiO 2 . The alkaline earth hydroxide may be formed by the reaction of an alkaline earth metal salt with an alkali metal hydroxide derived from the applied alkali metal silicate and is neutralized.
