Abstract: 1349444 Full face disc brakes; friction clutches BENDIX CORP 19 Feb 1973 [28 March 1972] 8089/73 Headings F2E and F2C A friction disc for a full-face mutli-disc brake or clutch comprises an annular core 58 preferably of beryllium or steel, the core having circumferentially-spaced radial slots 66 at the outer end of each of which is located, in a bore 84, a rivet 74 which secures a pair of carbon wear pads 54 in back-to-back relationship. On each face of the disc, between adjacent wear pads 54, is located an abutment member 87. Each head 76 of a rivet has a flange 88 which overlies an interior flange 92 in the opening 85 provided in the wear pad 54 for the rivet; a radial spacing A is left between the periphery of flange 88 and the edge of opening 85 so that tangential forces developed in the wear pads 54 during braking are transmitted to the abutment members 87 instead of to the rivets. The spacing A also permits movement between pad and core during differential expansion of the pad caused by heat developed during braking. Keyways 68 are provided. The disc shown is intended as a rotor for use in a known type of aircraft brake where the keyways engage keys located around the inner periphery of part of the rim of an aircraft wheel. Similar stators are engaged by keys located around a hollow torque tube secured to the fixed axle of the wheel. The discs are compressed against an outwardly-directed flange at the end of the torque tube by a circumferential array of fluid-operated pistons each separated from a common annular pressure plate by a block of heat-insulating material. The pads are moulded to shape or cut from a laminated product. The abutment members 87 may be integral with the core or spot-welded to it, and are thin to permit maximum pad wear. The slots 66 may extend from the outer periphery of the core.

Title: Improvements in or relating to magazines for machines for packing cigarettes and other staff-shaped articles
IPC: F16K31/34
Filed: 1932-03-18
Abstract: 380,731. Arranging cigarettes for packeting. AKTIEBOLAGET G. AREHNS MEKANISKA VERKSTAD, 20, Alstromergatan, Stockholm. March 18, 1932, No. 8146. Convention date, March 21, 1931. [Class 94 (i).] In machines for effecting the preliminary arrangement of cigarettes and the like for packeting, and in which a series of vertical receiving partitions are disposed beneath a hopper, the cigarettes in the hopper are maintained at an appropriate level by devices actuated by a movable wall of the hopper. The cigarettes gravitate from the main portion 1 of the hopper to a lateral receiving chamber 2 and pass down into the vertical partitions 12. If the level in the chamber 2 is sufficient, a movable wall 11 is urged by the pressure of the cigarettes in a clockwise direction about its pivot 8 so that an associated pawl 9 engages a ratchet wheel 7 on a shaft 6. This prevents the rotation of a sprocket wheel on the same shaft and a feeding roller 3, actuable from the sprocket by a chain, is immobilized. If the level in the chamber falls so that an insufficient number of cigarettes is present the wall 11 is moved by the weight of the pawl 9 so that the latter is disengaged, and a friction clutch between a sprocket 15 and the shaft 6 becomes operative so that the feeding roller 3 is rotated to pass more cigarettes into the chamber 2 until the pressure is again sufficient to cause the wall 11 to move the pawl 9 into engagement with the ratchet 7 to stop the feed. Thepawl may be positively disengaged at intervals by a cam 25 to assist the operation, and may be subject to the action of a spring. The feeding roller 3 may be replaced by vibratory or oscillating feed devices.

This freedom of flexure is obtained either by leaving the tracks free below the pivots as in Fig. 4, in which a supporting roller 23 is mounted at each end of the arm 11, or by mounting a roller or rollers on each rocker arm so as to be capable of a rocking movement independently of the other roller or rollers on the same rocker arm. In the construction shown in Figs. 1 and 3, a pair of rollers 10 are mounted on the ends of a lever or spring 13 pivoted at 14 on one end of the arm 11, a single roller 9 being mounted at the other end. The ends of the two arms 11 are connected to a lever 18, pivoted at 20 on the chassis, by flexible or universal joints comprising rubber discs 20 and bolts 21. The movements of the rocker arms and the lever 18 may be limited by stops. The pivot 15 of the idler roller 9 is carried by an arm 16 pivoted to the arm 11 and is adjustable, to tension the track, by means of an adjusting rod 17. In the construction shown in Fig. 7, the supporting rollers 30, 31 are carried by frames 32, 33 pivoted to the ends of the arms 11. Other frames may be pivoted to the frames 32, 33, the supporting rollers being pivoted to the ends of these additional frames. The loading on the rollers may be distributed equally or in any desired proportion. Spring may be used as the pivoted frames 32, 33.

Abstract: 670,027. Receivers and transmitters; diaphragms. GENERAL ELECTRIC CO., Ltd., and POLGREEN, G. R. March 27, 1950 [March 25, 1949], No. 8217/49. Class 40 (iv). [Also in Group XXXV] The permanent magnet and pole-pieces of an electromagnetic transducer are constructed from ferro-magnetic powder material which is bonded by a non-magnetic, electrical insulating medium such as a synthetic resin plastic, the powder material used in the magnet having a higher remanence and coercivity than that used in the pole-pieces. According to the Specification, the consequential reduction of eddy currents in the magnetic structure permits a more compact construction and enables the transducer to be used for the direct modulation of radio frequency currents by audio-frequencies or to operate at ultrasonic frequencies. As shown in Fig. 1, a telephone receiver comprises an axially-magnetized, hollow cylindrical permanent magnet 1 and a central pole-piece 2 which are secured together by an adhesive, the pole-piece having part of its surface insulated by a layer of paper or synthetic resin and carrying a coil 3 on a stem portion 8. A circular diaphragm 4 of magnetic material is supported adjacent to the magnet and polepiece. In a modified arrangement, Fig. 2, the diaphragm is non-magnetic and carries a central armature 14 formed of magnetic powder, the axial length of the central pole-piece being reduced and an annular pole-piece 13 secured by an adhesive to the magnet. An alternative arrangement, Fig. 4, comprises a radially-magnetized ring magnet 16 fitted between concentric pole-pieces 19, 20. The diaphragm 29 may be magnetic, or alternatively may consist of a circular disc of magnetic dust material fitted within an annular disc of plastic or phosphor bronze. A further arrangement, Fig. 5, usable as a telephone receiver or transmitter includes a circular magnetic diaphragm 32 secured between two hollow cylindrical magnets 33 which are both axially magnetized in the same direction. Annular pole-pieces each carrying a coil 40, 41 on a hollow, inwardlyextending portion 38 are secured by an adhesive to the outer ends of the magnets.

Abstract: 766,095. Gas manufacture. KOPPERS CO., Inc. March 22, 1955 [May 4, 1954], No. 8325/55. Class 55 (2). Low-temperature tar is mixed with a coal charge and subjected to high-temperature coking, whereby a portion of the lowtemperature tar is recovered as high-temperature. The low-temperature tar, which is produced by coking between 450‹ and 700‹ C., is mixed in the proportion by weight of 1 to 10 per cent of tar to 99 to 90 per cent of a coal suitable for high-temperature coking, the mixing preferably being effected outside the hightemperature coking-chambers. The mixing may be effected during the final crushing of the coal, and the coal may be of a high volatile type, or may be a blend of coals. The retorts may be horizontal, vertical or inclined. The lowtemperature tar may be mixed with char, from the low-temperature coking, and with the coal; the high-temperature coking being in the range 800‹ to 1150‹ C. In an example, 200 tons of char and 36 tons of tar from the low-temperature coking are mixed with 800 tons of highvolatile coal, the tar yield from the hightemperature coking being in excess of that from the coal alone by about one half of the weight of the low temperature tar used.
