Title: Piston-cylinder unit for hydropneumatic suspensions in vehcles
IPC: F16F9/50
Filed: 1970-10-29
Abstract: 1328409 Regulating mean height V LANGEN [trading as LANGEN & CO] 29 Oct 1970 [31 Oct 1969] 51533/70 Heading F2S In a piston-cylinder suspension unit which is maintained at a constant height by liquid supplied constantly from a pump 5 and discharged to a reservoir 6 when the piston 2 uncovers ports or grooves 8 in the cylinder 1, the rate of discharge is governed by the size of a constriction 10 through which the liquid must pass, and not by the extent to which the port or groove 8 is uncovered. The constriction 10 is constituted by a gap left between a bush 9, screwed into the cylinder 1 and projecting into the groove 8, and the piston 2. Between the constriction 10 and the reservoir 6 is a non- return valve 12 tending to close the line 11 but kept open by a control pressure supplied through line 13 from the pump 5. Thus if the pump fails, the valve 12 closes, as does the non-return valve 7, holding the piston in its existing position. The piston 2 may constitute the cylinder of a damping piston 17.

The material may also contain sensitizers such as Michler's ketone, naphthothiazolines, dyes, dimethylamine benzaldehyde or quinolizine-4- one. In examples, preferred polymers are vinyl alcohol polymer and copolymers containing mmethyl benzoyl, p-methyl phenylacetyl, p-ethyl benzoyl and 4-nitro-3-methylbenzoyl as groups in a side chain, epoxy resin with m-methyl benzoyl as side chain polyvinyl toluene, vinyl toluene/ styrene copolymer, a polyamide containing mmethyl benzoyl as a side chain and sulphochlorinated polyethylene containing m-toluidine groups. The polyvinyl alcohol derivatives are prepared by reacting polyvinyl alcohol with the appropriate acyl chloride in pyridine. Polyvinyl alcohol may be replaced (see reaction product in the description) by vinyl alcohol/ethylene copolymer, vinyl chloride/vinyl alcohol copolymer, epoxy resin of epichlorohydrin and 2,2-bis-(4- hydroxyphenyl) - propane. The polyamide derivative is prepared by reacting a polyamide of diethylene triamine and adipic acid with mmethylbenzoic acid chloride in water.

Title: Improvements in or relating to Extrusion Presses

Abstract: 1,152,219. Extruding. FIELDING & PLATT Ltd., and E. J. AVERILL. 24 Nov., 1967 [24 Nov., 1966], No. 52668/66. Heading B3P. An extrusion press has a hydrostatic extrusion chamber 21 containing an extrusion die 29 and a plunger 13 sealed thereto at 25 and extending rearwardly into sealing engagement at 18 with a pressure cylinder 9 containing pressure liquid which acts on the billet 28 in the extrusion chamber through a longitudinal passage 27 in the plunger, and safety means 20, 32 are provided to oppose a sudden forward movement of the plunger if the pressure in the extrusion chamber is suddenly dissipated. The extrusion chamber 21 is mounted in a crosshead 22 movable longitudinally by cylinders 24. The pressure cylinder 9 is mounted in a crosshead 10 movable longitudinally by cylinders 12. Plunger 13 is secured by plug 16 in a further crosshead 19 connected to the crosshead 10 by tension-failure studs 20 and shock absorber rods 31 carrying compressible rings 32 of ductile metal, such as zinc, or a plastic. Pressure cylinder 9 contains a pressurization plunger 7 connected to the main press ram 4 which acts in main cylinder 5. During extrusion, plunger 7 is moved forwardly to pressurize the fluid in cylinder 9 and chamber 21 thereby to extrude the billet 28 through die 29. Due to the differential action of the fluid on plunger 13, the latter may also move forwardly to maintain axial loading on the billet during extrusion. This axial loading is controlled between zero and a maximum by cylinders 12. If the pressure in chamber 21 drops suddenly due to complete extrusion of the billet, studs 20 fracture and the resulting forward movement of plunger 13 is cushioned by shock absorber rings 32. A further compressible ring 35 of ductile metal or a plastic is provided between the plunger housing 17 and the extrusion chamber. In another embodiment, Fig. 5 (not shown) the shock absorber comprises a billet (38) which is itself extruded through orifices (43) to cushion the forward movement. In a further embodiment, Fig. 6 (not shown) a fluid type shock absorber is used. This may be mounted between crossheads 10, 19 or between crossheads 19, 22.

In the embodiment shown, the internal conductor 112 of the first terminal element 111, 112 is common to three complementary terminal elements 211, 52, 51. Each terminal element is closed at one end by short-circuiting discs, e.g. 115, and the open ends are joined to the closed end of the preceding elements, or in the case of element 51, to the inner conductor 53 of the line by joints 109, 209 &c. water-tight but transparent to the wave-energy so that cooling water may be circulated throughout the elements through openings in the shortcircuiting discs. Each element 51, 52, 211 is surrounded by a cylindrical peripheral conductor, 58, 56, 26, connected between the outer conductor 54 of the line and the external conductor 111 of the first terminal element, thereby forming coaxial line sections.
