Title: Vehicle suspension systems
IPC: B60G17/027
Filed: 1971-09-28
Abstract: 1412736 Regulating vehicle suspension height JONAS WOODHEAD Ltd 22 Dec 1972 [28 Sept 1971] 45145/71 Heading B7D A vehicle suspension system comprises between each end the rear axle and the body of the vehicle a coil spring 101, 102 and hydraulic ram 107, 108 arranged in series, a level responsive valve arranged in each of the two units 113, 114 to admit fluid to the respective cam from a hydraulic accumulator in one unit 113 upon a low level being sensed, and a pump arranged in each unit 113, 114 to pump fluid from the respective ram to the accumulator upon a high level being sensed. The unit 113 comprises a body 1 in which is journalled a shaft 117 carrying a levelling cam 4 and an arm 115 linked to the axle so that the cam 4 oscillates as the axle moves up and down. When the vehicle body is at a high level in relation to the axle a helical wedge face 39 on the cam 4 engages a complementary face 40 on a spring- loaded pumping cam 11 which is reciprocated by axle movements so that a plunger 13 secured thereto pumps fluid from the ram 107 through non-return valves 14, 20 into an accumulator chamber 26 separated by a rubber diaphragm 24 from a pressurized gas chamber 25. When the body is at a low level a cam track 31 on the cam 4 acts through a push rod 30 to open a ball valve 28 so that fluid from the accumulator chamber 26 flows through the valve 28 and axial grooves in the push rod 30 to the ram 107. A relief valve 35 prevents excessive pressures in the accumulator chamber 26. The unit 114 is similar to the unit 113 except that the diaphragm 24, gas chamber 25 and relief valve 35 are omitted and is connected to the accumulator chamber 26 in the unit 113 by a line 119. A modified configuration for the unit 114 is deseribed with reference to Fig. 5 (not shown). Air springs combined with the rams in hydropneumatic units may be used instead of the coil springs 101, 102. The springs 101, 102 may carry all of the load exerted on the axle or further springs may be arranged in parallel therewith.

Title: Improvements relating to furnace recuperator air supply systems
IPC: C21D9/70
Filed: 1964-11-10
Abstract: 1,060,236. Furnace recuperators. REKUPERATOR KOMM. GES. DR. ING. SCHACK & CO. Nov. 10, 1964 [Dec. 17, 1963], No. 45835/64. Heading F4S. Means to prevent overheating of the heat transfer surfaces in a waste gas heat recuperator 3 consists of an air recirculating duct 6a extending between the recuperator air outlet 7a and a point upstream of the air fan 5 and downstream of a damper 8 controlled by a flow meter 9. As shown, the recuperator supplies air through a duct 7 to the burner 1a of a soaking pit. As the heat requirements of the soaking pit diminish (i.e. as the ingots therein become sufficiently heated), the burner air supply through pipe 7 is reduced and the damper 8 in the main air-supply duct 10 is almost closed. However, hot gases from the soaking pit continue to flow to the recuperator through the duct 2 at relatively high temperature. The increase in the pressure differential between the pipes 7 and 10 resulting from the turning down of the burner and partial closure of damper 8, causes through the duct 6g a recirculation of air through the recuperator sufficient to prevent overheating by the hot gases. When the damper 8 is fully open, only a relatively small amount of the air is recirculated through the duct 6a the pressure difference between the pipes 7 and 10 then being relatively small.

[Also in Division D1] A device for cutting a tubular fabric 13 made of or containing yarns of a thermoplastic material comprises means 10 for stretching the fabric 13, a cutting wheel 16 having a peripheral cutting edge arranged to contact one surface of the fabric 13, a pressure element 18 arranged so as to contact another surface of the fabric 13 at a region thereon opposite or nearly opposite to the region of contact between the wheel 16 and the surface which it contacts, and means for heating the element 18 to bring the fabric at the location where it is to be cut to a plastic condition. As shown, a tubular fabric 13 passes over a metal calender frame 10 consisting of two pairs of parallel arms 11, 12 and provided with raised entry arms 15. The hardened steel wheel 16 slits the fabric 13 longitudinally and is mounted so as to be freely rotatable horizontally in a recess 17 in one of the arms 11. The element 18 consists of an electrically heated metal bit 19 partially enclosed within a ceramic housing 20 adjustably mounted on a flat plate seated on a base adapted to move in slots in a horizontal bar extending across and beneath the frame 10. A rough adjustment of the heated means may be made by movement of the element 18 along the horizontal bar and a fine adjustment may be made by movement of the housing 20 on the base, this movement being imparted by rotation of a screw-threaded rod secured to the housing 20. Fabrics cut by this method may comprise yarns of synthetic linear polyamide or polyester condensation products, organic derivatives of cellulose, e.g. cellulose esters such as cellulose propionate, cellulose butyrate, cellulose aceto-propionate or cellulose ethers such as ethyl cellulose or benzyl cellulose, polyvinyl esters, polyvinyl alcohol, copolymers of vinyl halide and vinyl esters, polymerized vinylidene chloride or polymerized acrylic acid or acrylic acid derivatives such as polymerized methyl methacrylate. Non-thermoplastic yarns, e.g. cotton, silk, wool, linen or regenerated cellulose, may be included in the fabric and mixed yarns containing both thermoplastic and non-thermoplastic fibres may be used.

Abstract: 1,103,350. Casting processes. INSTITUT ELEKTROSVARKI IMENI E. O. PATONA. 16 Nov., 1965, No. 48549/65. Heading B3F. In a method of electroslag casting, a consumable electrode 9 is located in a water-cooled mould 5 open at both ends, the mould and electrode being moved towards each other during melting and subsequent casting so that a continuously cast ingot emerges from the bottom of the mould. Initially, the mould bottom is closed by a water-cooled plate 7 carrying a fusible member 8 of the same material as that to be cast. When the electric current is switched on, the electrode 9 melts n the mould 5 and is moved progressively downwards and when a predetermined level of metal has been reached, the lower portion of which has commenced to solidify, the mould is moved upwards towards the electrode so as to permit a solidified cast ingot to emerge from the bottom end of the mould carried on the plate 7. The speeds of the mould and electrode are related to rate of melting and the electric current supplied.
