Abstract: 732,876. Friction gearing. SPODIG, H. June 29, 1953, No. 17995/53. Class 80 (1). [Also in Groups XXX and XXXV] In magnetized rollers, wheels, pulleys and the like for use in conveying and supporting ferromagnetic bodies and as friction gearing, the peripheral surface is formed by the peripheries of rings of ferromagnetic material magnetized by permanent magnets mounted with their axes disposed radially or parallel to the axis of the roller &c. and by the peripheries of one or more rings or discs of non-ferromagnetic material disposed between the ferromagnetic rings or discs. The shaft 1, Fig. 1, carries a hub 2 of non-magnetic material on which are mounted ferromagnetic rings 3. Permanent magnets 4 arranged with their axes parallel to the shaft bridge the gap between the rings. A ring 5 of non-ferromagnetic material is inserted between the outer ends of the rings. The periphery of the roller may be profiled. A number of these rollers may be arranged side-by-side with like poles adjacent to one another. In a modification, Fig. 6, the permanent magnets 4 are arranged radially. The hub 2, which may be made of an aluminium or magnesium alloy, carries a ring 6 of ferromagnetic material on which the inner ends of the magnets rest. Rings 7 of ferromagnetic material are mounted on the magnets 4 and are separated by a ring 5 of non-magnetic material. The sides of the ring 6 and the inner ends of the magnets may be bevelled. The ring 6 may be omitted. In another modification, Fig. 9, a ferromagnetic body 9 having a central rib 10 is mounted on the hub 2. The magnets are arranged with like poles opposite to each other and carry rings 7 of ferromagnetic material. In a further modification, Fig. 11, the magnets 4 are inserted radially in recesses 12 in hubs 11 of ferromagnetic material and carry rings 13 of the same material. Rings 14 of non-ferromagnetic material are placed between the rings 13 and the sides of the recess. A component of this multiple system when used alone may have its peripheral surface sloped or formed as a convexity or concavity. When it is desired to rotate a piece of work, e.g. a tube 16, Fig. 16, during conveyance, one edge 17 of the hub 11 is made to project considerably beyond the other and the rings 14, 13 are bevelled. A stand 18, Fig. 19, provided with rollers 19, 20 may be used to hold a rod 21 while operations are performed on it. A number of such stands each carrying a single roller may be disposed more or less uniformly to support sheetmetal. When the distance through which an article is to be transported is less than the circumference of the roller, a segment 22, Fig. 20, is made non-magnetic, or substantially so, in order to facilitate removal of the article.

Title: Improvements in or relating to shock absorbers
IPC: F16F9/24
Filed: 1929-06-13
Abstract: 332,360. Stevens, A. H., (Delco Products Corporation). June 13, 1929. Fluid-friction vibrationdampers.-In apparatus of the type in which a piston works in a cylinder enclosed in a reservoir and in which liquid flows freely from the reservoir into the cylinder through a one-way valve in the piston during its upward movement while the flow of fluid from the cylinder into the reservoir through a relief valve is restricted during its downward movement, the relief valve is entirely supported by a resilient member in the port which it controls. The apparatus is mounted on the frame of a vehicle and the piston 28 is reciprocated vertically by a lever 35 on a spindle 36, carrying an operating lever connected by a strap to the axle. The piston is thus moved downwards by the pull on the strap and is returned by the helical spring 55 which keeps the strap taut. The spring 55 also holds in position the base plate 47 forming a seat for the one-way valve 51 which is guided by a central stem 49 riveted to the base 47. A light spring 52 holds the valve 51 in its closed position. When the piston is forced downwards considerable resistance is exerted to the escape of liquid from the cylinder through the relief valve 65 which is pressed on to its seat by the spring 66 and has no other contact with the walls or casing. The valve is formed with a guiding part 61 having an annular recess which communicates with the central recess in the valve through radial holes 68. When the valve lifts from its seat liquid flows through the radial holes outwards to the annular recess and thence past the valve seat to the reservoir.

Title: Improvements in or relating to liquid pressure braking systems
IPC: B60T11/224
Filed: 1936-07-01
Abstract: 477,839. Fluid - pressure brakes. AUTOMOTIVE PRODUCTS CO., Ltd., and BROCK, D. T. July 1, 1936, No. 18283. [Class 103 (i)] To provide adjustment for wear in a liquid pressure braking system having a compound master cylinder in which the travel of the low pressure piston terminates at a predetermined point in the travel of its actuating member, so that it displaces a constant volume of liquid, there is connected to the brake conduit a chamber the volume of which can be increased to an extent limited by a positive abutment and which receives a proportion of the constant volume displaced by the low pressure piston and means are provided for adjusting at will the permitted increase of volume of said chamber and therefore the proportion of liquid received thereby. The variable-volume chamber comprises a cylinder 11, one end of which is connected to the pipe leading to the wheel brake cylinders, the other end being closed by a cap through which passes a reduced and screwed portion 13 of a piston 12 loaded by a spring 15. The screwed portion carries a wing nut 14 by which the initial position of the piston may be adjusted. If the brake linings are new, the piston is adjusted so as to have its maximum stroke, but as wear occurs, the piston is drawn to the left so that less liquid from the master cylinder is admitted to the cylinder 11 during movement of the low pressure piston, and more passes to the brake cylinders. The initial volume of the cylinder is kept filled from the usual reservoir. The device forms a " single point " adjustment for taking up progressively the additional travel due to wear of the linings.
