An hydraulic shock absorber has a piston 4, Figs. 1 and 2, which is mounted on a piston rod 13, is reciprocable in a cylinder 1, and has passages 5, 6 therein which connect a chamber X of the cylinder with a chamber Y of the cylinder. An annular reservoir is formed between the cylinder 1 and an outer coaxial member 2, the reservoir being connected to the chamber Y through a valve 23 and passages 30, and being separated into chambers 32, 33 by means of a part annular wall 34 which extends around an arc of 220 degrees. A gap of 140 degrees in the wall 34 forms a connection between the reservoir chambers 32, 33. The passages 5 in the piston 4 are closed by a valve-plate 7 being urged by a spring 8 and the passages 6 are closed by a valveplate 10 being urged by a spring 11 and a nut 12. The piston-rod 13 passes through an end closure disc 14 and a seal 15 which carries a cover 16. The valve 23 is mounted in the cylinder 1, has a bore 24 closed by a disc 25 urged by a spring 26, the disc 25 carrying a valve member 27 which is urged by a spring 27a to close a passage 28 which extends through the valve member 27. In operation rebound loads are provided by the valve 10 whilst compression loads are provided partly by the valve 7 and partly by the valve 27. As the length of the shock absorber is reduced under compression loads, oil passes through the valve 7 and oil displaced by the piston-rod entering the cylinder passes to the reservoir 31, via passages 28, 30. The chamber 33 is maintained full of oil to prevent ingress of air therein and excess oil is passed through the gap in the part-annular wall 34 and into the chamber 32. On return of the piston rod, its volume is recuperated by oil from the reservoir 33 which passes through the valve 25 against the force of the spring 26, oil also passes through the valve 10 on the piston 4.

As shown in Fig. 2, a pair of frame members each having a blade member 3 and 4 are separated by a spacer 5 located at each end of the frames. The inner edge faces of the spacers are tapered for engagement with a correspondingly tapered metal wedge 7 e.g. of brass. The unit is assembled by placing the spacers between the two frames, partly inserting the wedge Fig. 5 (not shown), moving the wedge inwardly so that the tapered surfaces are in contact, then e.g. spot welding the frames to the spacers and, finally pressing the wedge further into the frames to thereby place the blades under tension; the total wedging taper may be formed in one end face only, the other end being square. The blade unit is then clamped between a platform member 1 and a cap 2 to form a cartridge unit. In modifications of the latter blade unit, both outer edges of the long sides of the frame may be sharpened, or the unit may have only a single blade to the ends of which blocks are secured to perform the function of the spacers 5. The blade assembly may also be made adjustable relative to the guard surface formed on the platform 1. In the embodiment shown in Fig. 10, two single blades 21, 22 are secured to spacers 23 having tapered surfaces such that the wedge 24, Fig. 8 is driven between the spacers in a direction parallel to the plane of the blades. In this embodiment the ends of the wedge are bent to form flanges (35) Fig. 12 (not shown) which enable the blade assembly to be secured in an integral metal pressing formed with a guard surface (30) Fig. 11 (not shown); the pressing together with the blade assembly form a disposable shaving unit.

Abstract: 1,206,607. Shovelling machines. CATERPILLAR TRACTOR CO. 16 Oct., 1967 [21 Oct., 1966], No. 47038/67. Heading E1F. [Also in Divisions F1 and F2] An hydraulic motor 20 for moving a mem- Iber 16, used e.g. to lift or tilt the bucket of a tractor mounted loader, is automatically arrested in a predetermined position by arranging the release of a detent device D which allows the motor's control spool valve 34 to return to its spring urged neutral position and thus terminate the pressure supply through line 68 to the motor. When the spool valve 34 is in its actuated position, pressurizing line 68, a spring 90 causes leftward movement of a plunger 138 and engagement of the detent device D (see Division F2). The plunger 138 moves the spool 126 of a slave unit S, Fig. 3, to a position wherein a recess 134 is aligned with passages 128, 156. During this leftward movement, fluid admitted to a cavity 144 during a previous cycle is returned to the reservoir through a valve 152 and a line 148. When the member 16 reaches the predetermined position a cam 106 operates a valve 110 so that a conduit 122 becomes pressurized from the supply line 68, 120. Pressure in the conduit 122 is communicated via the recess 134 and spool passage 142 to the cavity 144. This sudden pressurization of the cavity 144 moves the plunger 138 to the right and thus releases the detent mechanism D. Thus during each operation the chamber 144 is filled from the conduit 122 and is subsequently exhausted. This action automatically purges the conduit 122 of entrained air. Reference has been directed by the Comptroller to Specification 1,060,347.

Abstract: A start-up procedure for use in a high severity hydrodesulphurization process, which process comprises hydrodesulphurizing a residual-containing hydrocarbon feed which is composed substantially of hydrocarbons boiling above 482 DEG  C. and which contains a substantial quantity of asphaltic materials utilizing a catalyst comprising a metalliferous hydrogenating component composited with a support, the metalliferous hydrogenating component being in substantially sulphided form during the major portion of the hydrodesulphurization process, the hydrodesulphurization process being conducted so as to remove at least 70% of the sulphur contained in the residual hydrocarbon feed with a hydrogen consumption from 1 to 5 molecular weights of hydrogen per atomic weight of sulphur removed and at a temperature up to 454 DEG  C., is characterized by initially contacting a hydrocarbon which is substantially free of asphaltic materials with hydrogen in the presence of the catalyst comprising a metalliferous hydrogenating component composited with a support at a temperature from 121 DEG  to 260 DEG  C., a hydrogen partial pressure from 52.5 to 350 kg./cm.2 and at a space velocity from 0.1 to 10.0 volumes of the asphaltic-free hydrocarbon per hour per volume of catalyst, gradually increasing the temperature until a temperature in the range from 316 DEG  to 371 DEG  C. is attained, discontinuing contacting of the asphaltic-free hydrocarbon and commencing contacting of the asphaltic-containing residual hydrocarbon at substantially the same pressure and space velocity employed during contacting of the asphaltic-free hydrocarbon. The charge stock may be one of which 40% or more boils above 482 DEG  C. It may contain 10% by volume of asphaltenes.  The asphaltic-free hydrocarbon may be a propane deasphalted residuum, a vacuum distillate boiling up to 593 DEG  C., a gas oil, furnace oil, naphtha or gasoline.  It may also contain up to 4% by weight of sulphur.  The process may be commenced with the catalyst in a substantially unsulphided state, for example, in a partially sulphided state or in the oxide state, and the sulphiding effected by the sulphur-containing asphaltic-free hydrocarbon. Additional sulphur in the form of mercaptans or sulphides may be added to the asphaltic-free hydrocarbon.  The catalyst used in specific examples comprises nickel, cobalt and molybdenum supported on alumina.  The examples demonstrate the longer catalyst life obtainable with the process of the invention.
