Abstract: 899,274. Ball-and-socket joints. THOMPSON PRODUCTS Inc. Nov. 7, 1958 [July 30, 1958], No. 35847/58. Class 65(2). A bearing sleeve 10 of moulded synthetic resin material having a cleft 13 extending the full longitudinal length of the sleeve, a longitudinally converging outer surface and a part spherical inner surface to embrace the ball is sufficiently resilient to be sprung around the ball into snug engagement therewith while leaving a gap along the cleft to take up wear. The sleeve is employed in a socket 21 of correspondingly frusto-conical shape and is resiliently supported therein by an annular rubber block 31a or by a spring. A slot 14 in the inner surface of the sleeve affords greater resiliency to the latter and serves, together with the cleft 13, as a lubricant channel. Additional channels parallel to the slot 14 or a slot around the inner periphery of the sleeve may be provided. A rubber seal 32 may be attached to the socket by fingers 33.

Filed: 1975-09-02
Abstract: 1510853 Power steering arrangements R H SHEPPARD 2 Sept 1975 [1 Nov 1974] 36038/75 Heading B7H In a power steering system having two power units U 1 , U 2  fluid exhausted from a working chamber of unit U 1  is passed via line 57 to the housing 33 of the output member 33a of unit U 2  and then to the pump reservoir 56. This arrangement prevents build up of pressure in the output member housing caused by leakage from the working chambers, minimizes the temperature differential between the units and removes air bubbles from the working fluid. The units may be supplied by separate pumps and control valves but as shown one pump 53 supplies both units, a valve being provided in unit U 2  and the units being connected in series through working lines 45, 46. The fluid exhausted from a working chamber of unit U 2  is first passed through the housing 43 of the units output member 40a and then to line 57. The working piston of unit U 1  may be hollow (Fig. 2, not shown).

Abstract: 628,333. Sheeting plastic materials by rolling. SHAW, P. Dec. 6, 1946, Nos. 36093/46 and 24472/47. [Class 87 (ii)] A sheet of plastic material which has been formed between rollers A, B is removed from the roller B by a knife C which is held in yielding contact throughout its entire length with the roller surface by gravity or by spring action. The knife is screwed to a bar joumaled at D<SP>2</SP> in bearings which may be carried by the bearings of the roller B or may be independent thereof, and which are adjustable. The bar may carry a frame G<SP>1</SP> the lower member G of which serves as a rail along which a roller weight H<SP>1</SP> may run to a limit determined by adjustable stop bars J joined to the frame. The frame may be retained in the inoperative position, indicated by broken lines, by allowing the weight H<SP>1</SP> to move past the pivot D<SP>2</SP> of the frame. It is stated that the sheet clings to the roller B owing to this roller being heated to a higher temperature than the roller A.

The coated substrate may then be treated with a solution of a metal salt or complex thereof, the metal being one from Groups IB, IIB, IVB, VB, VIB, VIIB or VIII of the Periodic Table, and subjected to electroless plating and electroplating. In Examples phosphorus compounds produced by the reaction of white phosphorus with sodium methoxide, ethoxide, propoxide, butoxide, hydroxide or amide butyl magnesium, bromide, sodium-sec-butyl mercaptide, triethyl aluminium or lithium ethoxide are used.

Title: Improvements in tractor hydraulic power-lift systems
IPC: A01B63/111
Filed: 1956-11-27
Abstract: 847,089. Tractor power lift mechanisms. MASSEY-FERGUSON Inc. Nov. 27, 1956 (Dec. 8, 1955], No. 36197/56. Class 79(1). [Also in Group XXIX] A tractor hydraulic power lift system has in addition to an hydraulic actuator, connected to the hitch linkage, and a control valve controlling the admission of fluid to, and exhaustion from, the actuator, a descent restricting valve conected in series with the control valve to restrict the flow of fluid from the actuator to restrict the descent of the linkage to a predetermined maximum rate irrespective of the magnitude of the downward force of the linkage. A valve plunger 31 in the control valve V is operated manually or by draft control through a floating lever 45 to open or close ports 34 and 35 to supply or exhaust fluid from actuator 20, 21 to raise or lower, respectively, an implement, the plunger 3] returning to a neutral position where both ports are closed when the implement reaches a desired position. Fluid is taken from the sump through ports 34, 36 by the pump 30 and is pumped through passages 41, 40, oneway valve 43, passage 39, descent restricting valve V1, pipe 39<SP>1</SP> to the closed end of the cylinder 20 to raise the implement, a relief valve 44 being incorporated in the passage 39. The implement is lowered by its own weight exhausting fluid from the actuator through valve V1, passage 39, ports 35 to the sump. Valve V1 comprises a ball valve 61 biased by a spring 62 to close an orifice 50; a presser 70 abutting the ball 61 is engaged by a piston 71 which is moved by a spring 73 acting on a collar 79 fixed to a rod 74, the spring 73 being stronger than spring 62 to hold the ball 61 from the orifice to allow free flow of fluid either way. On lowering an implement, fluid passes under pressure through restricted ports 35 to the sump, and due to these restrictions pressure builds up in passages 39, 53 and 58 and acts through orifice 50 on piston 71 to counteract the pressure of the spring 73, the piston 71 being moved so that the ball 61 closes the orifice 50 until the pressure in passages 39 and 58 has decreased sufficiently to allow the spring 73 &c. to raise the ball 61. In this way the rate of descent of an implement can be controlled. The spring 73 can be preloaded by screwing its casing 77 along the body 56 surrounding the remainder of the valve V1, this determining the normal distance of the ball 61 from the orifice 50 so determining the rate of flow of fluid hence the rate of descent.

Title: Production of containers
IPC: B31B17/00
Filed: 1976-09-02
Abstract: A machine for transforming heat shrinkable thermoplastic material into sealed and liquid-filled containers in which the material in strip form is cut off to a suitable length then heated and transformed into a tube-shaped shell blank on a mandrel with an overlapped longitudinal heat-sealed seam. The shell is then displaced in relation to the mandrel so that its bottom end extends beyond the end of the mandrel, a base blank cut from another strip is then inserted into the end of the shell to rest against the mandrel end, and the shell and inserted base are then heated causing the shell to shrink accurately to the shape of the mandrel and the bottom edge zone of the heated shell to be folded in against the end of the mandrel and the edge of the base. The joined edge zones of the shell and base are then pressed together and heat sealed. The container is then passed to a filling machine where it is filled and closed by a lid.
