Abstract: 627,780. Sockets. SOC. GENEVOISE D'INSTRUMENTS DE PHYSIQUE. April 25, 1947, No. 11101. Convention date, May 3, 1946. [Class 83 (iii)] [Also in Group XXIV] A device for clamping and releasing a tool 6 in a rotary machinetool spindle 1 comprises a draw spindle 16 provided with a screwthread 24 co-operating with a screwthread provided in the tool, and a transmission mechanism connecting the spindle 16 to the tool spindle driving motor 14, the latter, when the toolspindle is thrown out of gear, acting on the spindle 16 through the intermediary of a coupling and causing, according to its direction of rotation, the tool to be clamped or released. The end of the spindle 16 remote from the tool is provided with a spring- pressed slidable sleeve 26 connected to a pivoted lever 29 coupled to the armature 31 of an electromagnet so that when the latter is energized the sleeve 26 is clutched to a ring 33 coupled by means of a friction clutch (see Group XXIV) to a driver 35 rotated from the motor 14 through reduction mechanism. To clamp the tool 6, a handle 50 is moved to throw the tool spindle out of gear and cause the driver 35 and ring 33 to be rotated at reduced speed. The electromagnet is energized by operating the push-button 51 to clutch the sleeve 26 to the ring 33 and thereby rotate the spindle 16 to clamp the tool. The electromagnet is then de-energized to de-clutch the sleeve 26 from the ring 33, and the handle 50 moved to put the tool spindle back into gear. To release the tool 6, the tool spindle is thrown out of gear and the push button 51<SP>1</SP> operated to reverse the direction of rotation of the motor and at the same time to energize the electromagnet to clutch the sleeve 26 to the ring 33 and thereby rotate the spindle 16 to release the tool. The electromagnet is then de-energized to stop the tool spindle motor. The electromagnetic means for coupling the spindle 16 to the ring 33 may be replaced by hydraulic or pneumatic means.

Abstract: 1518896 Disc mills T POZZATO M POZZATO and A POZZATO 23 March 1976 [4 April 1975] 11715/76 Heading B2A A disc mill has opposed disc mounts 7, 13 Fig. 1, at least one rotatable mount having positive drive means 3c, the rotational axis of the second mount being inclinable relative to the rotational axis 5 of the first mount. The second mount has a control arm 12 projecting axially thereof to fix the angular position of the axis 15 (the second axis) of the second mount. The free end portion of the control arm engages a rotary bearing 17, 17a, 17b, 18 Fig. 2 whose position is fixed but adjustable by an arrangement which comprises a retaining member 21 which has at least a restricted angular movement about a third axis 22' Fig. 5 at right angles to but substantially spaced from the axis of the first mount and substantially spaced from the second mount, and which has a translatory movement in a direction parallel to the third axis 22'. The retaining member is connected to the rotary bearing housing 18, and the rotary bearing permits some twisting movement between the control arm 12 and the retaining member 21 about an axis parallel to the third axis. A double-acting fluid-pressure actuator 28 Fig. 5, is connected to the retaining member 21 to move it parallel to the third axis 22' and thereby alter the inclination between the axis of rotation of the mounts and hence of the grinding discs mounted therein. The actuator 28 comprises two identical piston-cylinder units or rams 29, 129 mounted on a pivot bar 22. A sleeve 38 is fixed to cup-shaped members 33, 133 which form the movable part of the actuator. The retaining plate 21 is fixed rigidly to the sleeve 38. To tilt the arm 12 the actuator 28 moves the retaining plate 21 by supply of pressure fluid to a chamber 36 via a connection 37 and release of fluid from the corresponding chamber 136 via the connection 137 or vice versa. The connections are then blocked off by a closed centre spool valve, not shown. The axial distance between the discs can be varied by varying the distance between a seating member 10 and a cylindrical body 2 Fig. 1.

Abstract: 800,265. Making heat-exchange elements. DAVIES, G. April 17, 1956, No. 11721/56. Class 83 (2). [Also in Group XIII] A fin for a heat-transfer element is made by making a series of cuts 2a extending inwardly front both longitudinal edges 3, 4 of a metal strip, to form a series of aligned pairs of ribs 5 extending from a sping 6, and bending the ribs out of the plane of the strip, and inwardly of the spine to position the free ends 9 of each pair in abutting relationship over the spine and spaced therefrom. The ribs may be curved throughout their length or they may only be curved near their outer ends, Fig. 9 (not shown). The strip is preferably of copper or aluminium and may have a thick centre part 11 forming the spine 6, Fig. 5, and tapered edge portions 12 forming the ribs. One side 13 of the strip may be flat or both sides may taper, Fig. 6 (not shown). After cutting and bending of the ribs the fin 10 is curved into a helix, Fig. 4. The cutting, bending and longitudinal curving of the fin may be performed by a single set of guillotine blades. To form a heat-transfer element, the fin is wound under tension on a tube 19, Fig. 7, preferably as it leaves the guillotine, the tube being rotated intermittently to facilitate winding. To aid heat transfer the tube may be coated with powdered aluminium, copper or other metal. Flanges 20 soldered to the tube have fingers 21 engaging the adjacent ribs to hold the fin in position. Alternatively the fin may be brazed or soldered to the tube, e.g. by dipping in a solder bath which also solders together the abutting ends of the ribs 5.

Abstract: 1399371 Displays INTERNATIONAL COMPUTERS Ltd 12 March 1973 [15 March 1972] 11925/72 Heading G4H In a matrix display, the illumination brightness at each of a matrix of positions is controlled by selective energization of an appropriate combination of a plurality of gas display cells at that position in response to decoding of a brightness code. As shown, each matrix position 2 contains four cells 1 of brightnesses (when energized) in the ratios 1:2:4:4 (achieved by weighting of the resistors 6 or optical filters or inherent brightness differences of the cells). With X and Y addresses registered at 9, 9a and 10, 10a respectively, with the least significant bit in each case being stored at 9a or 10a and being initially " zero ", the top left cell of one of the positions 2 is selected via decoders 7, 8 and networks 20, 21 and, if an OR gate 19 is producing a " one " output, is energized. The stages 9a, 10a form a 2-bit counter which is driven to select the other cells of the selected position 2 in turn similarly. The count at 9a, 10a is decoded at 12 to connect the outputs 17d-17a of a coder 16 to OR gate 19 in turn. Coder 16 codes the brightness required at the selected position 2, as registered in a register 15.

Abstract: 644,943. Machinery safety devices. SOAG MACHINE TOOLS, Ltd. April 30, 1948, No. 11959. [Class 80(iv)] [Also in Group VIII] In a guillotine machine in which the knife is actuated from a driving member through a connection which is automatically rendered inoperative when the machine commences to overrun, the disconnection of the knife from the driving member also results in the locking of the knife in its raised position. As shown in Fig. 2 a driving wheel 10 has a crank pin 9 engaging in a slot 8 formed in a lever 7 oscillatable about a shaft 6 to which is secured a lever 4, the two levers being normally connected by means of a latch device and thus forming a single rigid lever to which are connected pull rods 2 for the knife. The latch device comprises a pawl 13 pivoted to the lever 4 and normally urged into engagement with the lever 7 so that movements of the latter are transmitted to the lever 4. Under over-run conditions a cam (not shown) mounted on shaft 28, operates through mechanism (not shown) a lever secured to shaft 27 to which is also secured a lever 26 which turns clockwise to the position shown in Fig. 3 and rotates the pawl 13 about pivot 12, thus disconnecting the levers 4 and 7. Rotation of the pawl brings an abutment 23 thereon directly above an abutment 22 on the machine frame preventing downward movemement of the knife until the mechanism has been re-set by the operator.

Title: Improvements in or relating to rubber springs
IPC: F16F1/40
Filed: 1945-05-14
Abstract: 596,333. Rubber springs; vehicle suspensions. FIRESTONE TIRE & RUBBER CO. May 14, 1945, No. 12071. Convention date March 1, 1944. [Classes 108 (ii) and 108 (iii)] A rubber spring particularly for aircraft landing-gears and vehicle suspensions comprises discs 20, Figs 1 and 5 each consisting of concentric rubber rings permanently attached to the convex surface of a thin metallic plate 23 of conical shape. The discs are mounted between end plates 10, 14 secured respectively to the fuselage and landing-gear of an aircraft, the plate 14 and discs being guided centrally on a tube 11 fixed to the plate 10, and each disc comprises two rubber rings 21, 22 vulcanized to the plate 23 and spaced, or connected by a thin rubber layer to provide a circular groove 24. The inner periphery of each ring 21 is shaped as shown in Fig. 5, having a tapered portion 34, 35 and having vulcanized thereto a layer of fabric 27 impregnated with a lubricant which is solid under low stress conditions but liquefies under high stresses. Each plate 23 is formed with a concentric boss 32 which underlies the groove 24 between the rubber rings and contains air holes, and is adapted to project into the groove 24 of the next lower disc to maintain the discs in alignment. As the spring is compressed, the rubber bulges radially inwards so that the sharp edges 35 of the inner rings are flattened against the tube 11 providing frictional resistance which progressively increases with increase in the area of contact of the rubber with the tube. The air in the grooves 24 is gradually squeezed out through the holes in the plates 23 to the atmosphere through a hole 36 in the plate 10. Under extreme compression the grooves 24 vanish and the spring acts as a solid rubber cushion. On expansion, little frictional resistance occurs as the inner peripheries of the rings 21 move along the tube 11, and as the grooves 24 take their normal shape, the air flowing in from outside the spring cools the rubber. A groove 28 relieves strain at the outer periphery of each ring 22. Fig. 9 shows the spring interposed between the arms 51, 52 of an automatic wheel suspension linkage, and the spring is also shown interposed between the chassis and the suspension arms of the half-track bogie wheels of a military tank or tractor.
