Title: Improvements in or relating to shock absorbers
IPC: F16F9/34
Filed: 1951-01-15
Abstract: 681,650. Hydraulic shock-absorbers. FERRAROTTI, G., and GUASSO, F. Jan. 15, 1951 [Sept. 19, 1950], No. 1124/51. Class 108 (iii). An hydraulic shock-absorber comprises a cylinder 1 incompletely filled with oil, and a piston 2 having flow ports 27 normally closed by an automatically - operating valve, which is formed by a cylindrical rubber block 30 carried on a bush 34 disposed on the piston rod, between the piston 2 and a valve disc 35, the bush 34 providing means by which the pressure exerted by the valve disc 35 against the block 30 may be varied. Suitable selection of the length of the bush 34 thus determines the desired damping effect of the shock absorber. In operation, on compression at a low velocity, liquid passes from the ports 27, into ports 31 in the rubber block 30, and through orifices 36 in the plate 35. At greater velocities, the pressure developed in a recess 32 in the upper face of the rubber block 30 enables liquid to escape through the peripheral joint between the rubber block 30 and the plate 35.

Title: Directive antenna system
IPC: H01Q15/02
Filed: 1948-01-16
Abstract: 660,788. Directive-radio systems. STANDARD TELEPHONES & CABLES, Ltd. Jan. 16, 1948 [Jan. 16, 1947], No. 1368/48. Class 40 (vii). A continuously rotating directive aerial system comprising a primary aerial element 1 and a radiator 2, comprising either a horn as illustrated or a paraboloidal reflector, is surrounded by a lens structure 3 comprising a plurality of radiallypositioned conducting plates forming wave-guide elements modifying the phase velocity of the radiation passing through them, the elements 1, 2 being continuously rotated by a motor 4. The plates are so shaped that a spherical wavefront diverging from 1 would produce an equiphase surface over the outer surface of the lens 3. To produce a narrow beam the phase must be equalized over the target plane to the outer lens surface touching the surface along the axis of the radiation. This is achieved by inserting metallic plates into the horn 2 so as to advance the phase of the waves which diverge from the horizontal axis of the system 1, 2 with respect to those radiated along this axis. The lens thus functions to sharpen the rotating beam in the vertical plane while the horn 2 provides a narrow beam in the horizontal plane. If it is desired to tilt the radiated beam in elevation the outer surface of the lens 3 may be suitably conically shaped. Specification 650,767 is referred to.

Abstract: 1,018,391. Coating with pre-formed sheets. STONEY BROS. & CO. Ltd. Feb. 11, 1964 [Jan. 14, 1963], No. 1610/63. Heading B6G. [Also in Divisions A3 and F2] In a method of covering articles such as umbrella handles, and shoe heels, with shrinkable thermoplastic sheet material, e.g. polyvinyl chloride, the sheet is first converted into a sleeve by seam-welding together, e.g. by di-electric welding, two overlapping marginal portions arranged edge-to-edge then turning the sleeve inside-out, so that the welded margins lie within it, slipping it on to the article, and finally shrinking the sleeve on to the article. If desired, the sleeve may be expanded, e,g. by compressed air, to facilitate its introduction on to the article. Shrinking may be accomplished by heating the whole assembly in an oven temperature of, e.g., 80-150‹ C. Alternatively instead of, or at the same time as, heating the sleeve may be shrunk by treating it with an organic liquid, e.g. ethyl-acetate or with a vapour of such a liquid. The article, or the sleeve or both, may be coated with an adhesive before the sleeve is fitted to an article. In one embodiment the residual solvent of the adhesive coating the article serves as the organic liquid causing shrinkage of the sleeve which may also be treated with additional liquid. The sheet material of the sleeve may be initially embossed or printed with a decorative pattern. As shown a rectangular sheet 10 of shrinkable plastics has its two opposite edges seam-welded at 12 to form a cylinder with a slight taper 14 at a closed end. Reversal of the sleeve can be accomplished manually or by using a vacuum tube.
