Title: Improvements in rubber torsional shear spring vehicle suspensions
IPC: B60G11/23
Filed: 1951-11-14
Abstract: 743,976. Rubber springs; road-vehicle spring-suspensions. MOULTON, A. E. March 19, 1953 [Nov. 14, 1951], No. 26640/51. Classes 108 (2) and 108 (3). In a vehicle spring suspension including a rubber body 8 functioning in shear between inner and outer metal elements 14, 9, the rubber body 8 is bonded to the inner surface of the element 9, which is of deformable trough-like cross-section with flanges 10, 11, projecting beyond the surface of the rubber and closed by a plate member 12 extending transversely of the vehicle, wheel-supporting arms 25 being carried on the inner element or elements 14 at each end of the member 12. As applied to a trailer suspension, a stub axle 18 is bolted to the arm 25 and a beam 26. The arm 25 is bolted to a flange 28 welded to the inner element 14. The inner end of the beam 26 carried by a bolt 32 which is rigid with the element 14. The element 14 may extend to the other side of the trailer and carry a second axle 18. Where an independent suspension is needed, the element 14 and rubber body 8 are divided medially into two independent sections within a unitary outer shell 9. A bearing 21 for the inner element or elements 14 may be mounted on the shell 9. In a modification (Figs. 1 to 4, not shown), the beam 26 is dispensed with and the member 25 is of more solid construction. The axle ends of the member 25 may be connected by a dead axle. Specifications 676,098 and 676,190 are referred to.

Title: Improvements relating to the heat treatment of hydrocarbon gases
IPC: C07C2/00
Filed: 1927-10-08
Abstract: 309,455. Anglo-Persian Oil Co., Ltd., Dunstan, A. E., and Wheeler, R. V. Oct. 8, 1927. Drawings to Specification. Aromatic hydrocarbons; olefines, &c. are obtained by heat treatment of gases containing gaseous paraffins, e.g. natural gases, gases from cracking plants, stills, low temperature carbonization retorts etc. The gases are passed through a preheater at a temperature below that at which decomposition occurs, e.g. below 550‹ C., and then through reaction tubes or passages, wherein the gas is heated within a determined temperature range and for a determined time according to its composition. For example, the following temperature ranges are given for separate gases :-Methane 850-975‹ C.; ethane 800-900‹ C.; propane 750-850‹ C.; butane 700-800‹ C. and pentane 650-750‹ C., the ranges being modified accordingly when mixtures of the above gases are treated. The velocity of the gas is suddenly reduced on exit from the reaction tubes, for example, by the provision of an expansion box, whereby the gas is cooled and t<T>i.6 deposition of free carbon facilitated, the gas being then further treated. An inert gas, preferably superheated steam, may be admixed with the gas before entering the preheater or the reaction tubes, increasing the yield of liquid bodies and reducing the free carbon produced. After removal of tar and other condensible bodies, part or the whole of the residual gas may be recycled through the plant. The gas to be treated may be stripped of condensible hydrocarbons or hydrogen sulphide in any known manner. The reaction tubes may be smooth or packed with an inert or feebly catalytic substance, such as pieces of fire-brick or silica, or the internal walls may be ribbed etc., to increase the turbulence of the gas. The residual gas, if containing carbon monoxide and hydrogen, may be used to produce oxygenated hydrocarbon derivatives, e.g. a.lcohol &c., or for the production of carbon black. The olefines formed may be used to produce alcohols, esters, &c., while the liquid aromatic hydrocarbons and higher olefines are useful to produce anti-detonating motor spirit.

Title: Improved power steering mechanism for motor vehicles
IPC: B62D5/087
Filed: 1954-09-15
Abstract: 763,659. Vehicle power steering. GENERAL MOTORS CORPORATION. Sept. 15, 1954 [Oct. 28, 1953], No. 26743/54. Class 79(5). [Also in Groups XXIV and XXIX] A spool valve in a fluid-pressure power steering mechanism is mounted on a shaft which is rotatable by a manually-operated steering control member and is axially movable a limited amount by reaction consequent on the manual steering effort, and, in the neutral position, the valve is slightly spaced from thrust members on the shaft by which the axial movement of the shaft is transmitted to the spool and is also radially spaced from the shaft to correct for misalignment of the shaft and the ported valve casing. The steering column 12 includes a direct connection to the drag link (not shown) through a screw 12A, nut 30, rack 32, and pinion 34. The servo-piston 19 carries a rack 44 also in engagement with pinion 34, this rack and pinion being kept in engagement by a saddle 52 pressed down by a screw 50 engaging the gear casing. The steering column runs on needle bearings 40 and where it passes through the control valve box, is provided with leakage-preventing packing 41. The valve comprises a spool 124 with three lands co-operating with a grooved casing in such manner that, in the neutral position, there is a constant circulation of liquid through a pump to both sides of the servo-piston and to a reservoir. To allow for misalignment of the steering column and valve casing, the valve spool has a slight radial clearance from a sleeve 98 located on the column by a rubber ring 146 ; and the spool also carries end projections 150 which, in the neutral position of the valve, are spaced slightly from washers 110 constituting races of ball thrust bearings at each end of the valve. The bearings and sleeve 98 are resiliently clamped against a shoulder 106 on the steering column by a belleville spring 144 and a nut. To centre the valve, pairs of plungers 120 in bores surrounding the valve are urged into contact with the washers 110 by springs 118 and by the pressure of the inlet liquid entering the bores through restricted openings 152. Groove 84 receives pressure liquid from the pump, grooves 86, 88 connect to the reservoir, and connections to the two sides of the servo piston lead to ports in the valve casing between the grooves 84, 86, 88. The steering column moves axially, and so actuates the valve, when there is a reaction thrust to direct steering of (say) 3 pounds at the steering wheel.

Filed: 1927-10-10
Abstract: 279,075. Maschinenbau-Akt.-Ges. H. Flottmann & Co. Oct. 14, 1926, [Convention date]. Compressed-air engines. - In a jigging conveyer wherein the retardation required at the end of the feed stroke is produced by compression and advanced inlet, the exhaust passa.ge q of the power cylinder a is provided with a valve s for regulating the compression. The motor has a main cylinder a and a supplementary cylinder b. The conveyer trough is moved upward by fluid supplied to the left hand of cylinder a, and downward by gravity and fluid supplied to the right hand of cylinder b. With the valve in the position shown in Fig. 4, compressed air passes from the supply f to the centre of the valve through passage i to cylinder a and drives the piston d to the right. When a port l is passed, air passes to the valve and throws it to the left. The main cylinder exhausts by passages n, k. Fluid passes through a port k to the cylinder b to assist piston e to the left. When the piston d strikes the auxiliary valve o, the valve h is moved to the right and air is supplied to cylinder a to cushion the piston d. The exhaust leaves the cylinder by a piston-controlled passage q the valve-controlled bye-pass r of which is also controlled by the piston to effect cushioning.
