Title: Differential
IPC: F16H48/40
Filed: 1955-09-14
Abstract: 785,392. Differential gearing. ALLISCHALMERS MANUFACTURING CO. Sept. 14, 1955 [Sept. 28, 1954], No. 26345/55. Class 80 (2). A bevel gear differential for motor vehicles, comprising a rotary cage 11, a pair of bevel sun gears 33, 34 and a number of bevel planet pinions 53 in mesh with the sun gears, is characterised by the cage 11 having at least one peripheral aperture 51 so proportioned and arranged with respect to the sun gears that they can be put into or taken out of the cage therethrough, a releasable cover 54 for the aperture serving, when in position, as a mounting means for one of the planet pinions. As shown, the cage 11 has three apertures 51. The shaft 56 of each planet pinion 53 is secured, e.g. by welding, to a disc-like member 54 having a coned periphery 69. A ring 62 is secured in each aperture 11 by screws 63, and has an internal conical surface frictionally engaged by the conical surface 69 on one of the discs 54. Relative rotation between the sun gears 33, 34 causes the planet pinions 53, and with them the discs 54, to turn relatively to the rings 62. Friction between the discs 54 and rings 62 opposes relative motion between the two sun gears. Shims 71 placed between the rings 62 and the cage 11 can be used to adjust the relative radial positions of the planet pinions 53. To take the sun gears 33, 34 out of the cage 11, the rings 62 and planet pinions 53 are first removed. Half-shafts 38, 52, carrying the sun gears 33, 34, are next withdrawn. Each sun gear 33, 34 is, in turn, then moved axially to the position shown dotted at 73 in Fig. 2, and outwardly through one of the apertures 51. In one modification, Fig. 4 (not shown), the disclike member 54 is formed with two frustoconical surfaces at its periphery, facing inwardly, and co-operating with similar frusto-conical surfaces on the ring 62, and in another similar modification, Fig. 5 (also not shown), the frustoconical surfaces on the ring 54 face outwardly.

Patent GB-646162-A (GB)
Title: Improvements in or relating to thermoplastic synthetic resinous materials
IPC: B29C59/00
Filed: 1947-09-30
Abstract: Polymethyl methacrylate is produced in the form of a sheet or shaped article which exhibits a granular appearance, by disintegrating the material into granules, applying heat and pressure to form a sheet or shaped article and, after cooling, re-heating with or without light pressure to a temperature above 200 DEG  F.  Alternatively, after the initial sheet has been formed by heat and pressure, the pressure is released at least partially and the temperature maintained at a value above 200 DEG  F. until the desired appearance is produced.  As an example, grains of 2 to 3 mm. cube size are heaped between platens heated to 320-340 DEG  F. and moulded under a pressure of 0.25 tons/sq. inch for several minutes, the material being allowed to flow freely during formation of the sheet.  The sheet is cooled to between 60-100 DEG  F. and then reheated in the open press to between 250-300 DEG  F. for between 5-15 minutes.  In a modified process, after the formation of the sheet the platens are allowed to cool to a temperature between 210-230 DEG  F. and the pressure partly relieved. The sheet may be further shaped by pressure in a cold mould or by blowing it into a mould or jig whilst still warm.  The starting material, the sheet as initially formed in the press, or the finished article, may be tinted or dyed.  Plasticizers such as vinyl resins may be incorporated in the methyl methacrylate.  High frequency, infra-red or steam heating may be used in the process.  When the heating is done in two stages the sheet or article may be dipped in a solvent before final heating to impart a wrinkled appearance to the product.

Abstract: 837,528. Pistons. GRATZMULLER, J. L. Aug. 20, 1958 [Aug. 23, 1957], No. 26772/58. Class 122 (1). [Also in Group XXIX] A piston and cylinder assembly for a freepiston type hydropneumatic accumulator comprises a piston 2 having a rebate in which is mounted an elastically and plastically deformable sealing ring 4 of a material which, in order that the ring may be deformed into sealing contact with the cylinder 1 by a spring 5 acting through a compressor member 6, needs to be subjected to a pressure at least equal to the maximum operating pressure in the cylinder ; further, the material of the ring has a coefficient of friction of the order of 0.05. The sealing ring 4 may be made of polytetrafluoroethylene and is formed with cross-sectional dimensions small in relation to the cylinder diameter, the spring 5 being suitably designed to load the ring so that it makes adequate sealing contact around its complete circumference. The physical properties of the material of the ring are such that when the liquid in the accumulator has been exhausted and the piston 2 abuts the cylinder head, the pressure of the gas acting on the member 6 in addition to the spring pressure does not cause the ring to be extruded between the piston and cylinder. The spring 5 acts between an abutment plate 13 retained on the piston rod 12 by a nut or circlip 14 and is located by portions 8, 9. The member 6 is located on a spigot 7 and, in order to permit freedom of angular movement, its locating diameter is radiused at 11 and its outer diameter is suitably tapered. Specifications 702,088 and 712,577 are referred to.
