Title: Removal of aromatic impurities from paraffinic feeds
IPC: C10G45/10
Filed: 1974-07-29
Abstract: 1469309 Hydrogenation of aromatic hydrocarbons UOP Inc 29 July 1974 [30 July 1973] 33370/74 Heading C5E Substantially aromatic-free paraffins are obtained by treating a paraffinic feed boiling in the range 150-287 C. with hydrogen in the presence of a catalyst comprising an inorganic oxide support which has been surface-impregnated with a Group VIII metal component. The hydrogenation can be carried out at 200-500 C., a hydrogen pressure of 7À5-275 atmosphere absolute, a hydrogen to hydrocarbon mole ratio between 1 : 1 and 100 : 1, and a LHSV of 0À1 to 10. The feed can be obtained by the separation of aromatic and paraffinic hydrocarbons using a molecular sieve adsorbent. In examples, a feed boiling from 206 to 287 C. is hydrogenated using an alumina which has been surface-impregnated with 0À75 wt. per cent Pt and a feed boiling from 150 to 200 C. is hydrogenated using a silica which has been surface-impregnated with palladium. Surfaceimpregnated alumina catalysts, rather than uniformly impregnated alumina catalysts, are obtained by impregnating alumina with aqueous aqueous H 2 PtCl 6  from which the conventional excess of HCl has been omitted.

Abstract: 939,874. Making finned tubes; welding by fusion; straightening. BABCOCK & WILCOX Ltd. Sept. 19, 1962 [Sept. 20, 1961], No. 33740/61. Classes 83 (2) and 83 (4). Diametrically opposed longitudinally extending fins are fusion welded to a tube by simultaneously forming diametrically opposed fillet welds. The fins 36 prepared with 30 degree bevels are tack-welded to the tube 24 which is coupled to a carriage power-driven along the bed 8 of the welding machine. The assembled tube 24 and fins 36 are fed between two sets of rolls 34, 38 one on each side of the welding station. Each set of rolls 34, 38 comprises a pair of shafts 44 spring-loaded towards each other and each carrying a grooved roll 40 engaging the tube 24 and two rolls 42 engaging the fins 36. The rolls 42 of the leading set 34 are frusto-conical to incline the fins 36 at about 3¢ degrees away from the welding grooves whereas the rolls 42 of the trailing set 38 are cylindrical with edges bevelled where necessary to allow passage of the welds. Additional rolls 85 associated with each set engage the edges of the fins 36. Adjacent the welding-point, the fins 36 are engaged by grooved rolls 64 adjustable by wheels 72 and supported on spring- loaded frames 80. The welds are made by carbon dioxide shielded arc welding heads 4 adjustably mounted and directing consumable electrodes horizontally into the welding grooves 86. The initial 3¢ degrees inclination of the fins 36 serves to ensure the proper angular positioning of the fins 36 after shrinkage of the metal as the weld cools. At the exit end of the machine adjustable rollers 88, Fig. 4, bear on the fins 36 to correct deviation of the fins from the diametrical plane. In a modification, four welding heads make fillet welds on both sides of each fin simultaneously.

Title: Piston for a hydraulic shock absorber
IPC: F16F9/348
Filed: 1972-07-20
Abstract: 1402622 Shock absorber pistons; valves C BOURCIER DE CARBON 20 July 1972 [21 July 1971] 34063/72 Headings F2S and F2V A shock absorber piston valve comprises a floating double acting valve member 3, bearing on a surface la on the piston 1 and on a float support washer 8, and centred by a washer 9, of a smaller diameter than the support washer 8, disposed between the piston 1 and the support washer 8, and having at least one notch 9a in its periphery. The valve member 3 (which may be a stack of discs, not shown) has bores 3a which constitute permanently open passages through the piston. There is effectively no clearance between the washer 9 and the valve member 3. Thus when the inner periphery of the valve member 3 lifts off the support washer 8, the flow is determined by the effective cross-sectional area of the notches 9a, which is itself dependent on the lift of the valve member. This gives a linear damping characteristic. The washer 9 is thinner than the valve member 3 so that the latter is prestressed. A retaining disc 7 damps vibrations of the valve member 3 by regularizing the flow along the valve member. The internal diameter of the supporting surface 1a on the piston is between 80% and 90% of the diameter of the valve member 3. The piston 1 consists of an inner part 1d connected to an outer part 1b by radial partitions 1c.

Title: Improvements in or relating to means for producing super- or sub-normal pressure in a fluid system
IPC: B60T11/16
Filed: 1929-11-11
Abstract: 343,129. Fluid - pressure brakes; aeroplane control mechanism. INDIARUBBER, GUTTA PERCHA & TELEGRAPH WORKS CO., Ltd., 106, Cannon Street, and AVERY, W. L., of India- Rubber, Gutta Percha & Telegraph Works, Silvertown, both in London. Nov. 11, 1929. No. 34333. [Class 103 (i).] In brake operating means for producing supernormal or sub-normal pressure in a fluid system for operating a vehicle or aeroplane brake or brakes and of the type in which relative movement of two members, such as a cylinder and piston, increases or reduces the volume of a fluid-containing chamber so as respectively to suck fluid into or expel fluid from the chamber to the brakes, a pivoted operating-lever is operatively connected by a cam-slot with one of the relatively movable members so that when the lever is moved to reduce the volume of the chamber the pivot of the lever and the member to which the latter is connected by the cam-slot are caused to approach one another. In the construction shown in the Figure a cylinder 10, containing a piston 13 having a long skirt, is fixed by a saddle 11 to a member 12 which may be a frame member of a vehicle or the rudderbar of an aeroplane. The valve arrangement for regulating the supply of fluid into the cylinder is the same as that described in Specification 340,222, the valve being contained in one end of the cylinder and so connected with the piston that it is open only when the volume of the cylinder is a maximum. The piston 13 is moved against the action of tension springs 19 by a pedal 18 formed on a pair of bellcrank operating-levers 15 pivoting on an axle 16 fixed to the cylinder and each having a cam-slot 17 engaging a pin 14 each end of which projects through the piston-skirt 13 and through a slot in the cylinder wall parallel with the cylinder axis. The shape of the cam-slots 17 is such that the leverage of the levers 15 on the piston increases as the piston moves forwardly in the cylinder. The pedal 18 may be replaced by a hand-lever, in which case triangular apertures may replace the cam-slots 17, or other means, such as a hinged joint in the handlever, may prevent the latter from effecting retraction of the piston. Further, each operating lever 15 may be pivoted in the neighbourhood of its angle about the pin 14 and have a cam-slot at the end of one of its arms to engage a fixed abutment corresponding to the axle 16.
