Title: Belt driven reel unwinding device
Inventor: CUNNINGTON HARRY
IPC: B65H16/10
Filed: 1983-03-16
Abstract: A powered web unwind device comprises a web reel mounting (10), a light-weight sensor (18, 20) for sensing the configuration of an unwind loop downstream of the web reel mounting and a driven toothed belt (32) contacting the periphery of the web. The belt (32) is driven intermittently in dependence upon the location of the light-weight sensor (18, 20). The linear velocity of the web is maintained constant irrespective of the reel diameter at any given instant and the sensor and corresponding intermittent operation of the motor merely serve to ensure that the actual velocity is closely matched to the desired velocity. <IMAGE>

Title: Disc drive system
Inventor: OTAVSKY PAVEL
IPC: G11B25/04
Filed: 1984-05-09
Abstract: A plurality of rigid magnetic discs 37 are driven by a DC brushless motor 43. A blower wheel 65 also driven by the motor is used to create a flow of air for use in removing heat generated in the operation of the electrical and mechanical components in the system is disclosed. The motor includes a cup shaped rotor 45 having a plurality of magnets 56 on its side wall and a stator 51 having a series of windings 61 on a core 59. The rotor is attached directly to a spindle 15 on which the discs are mounted and the stator 51 is mounted on a spindle housing 23 in which the spindle is journalled. The stator is located radially inside the magnets on the rotor so that the magnets rotate outside the stator. The blower wheel is attached directly to the rotor. The flow of air created by the blower wheel as the rotor turns is channeled by a duct assembly 83 so as to pass from the blower wheel the front of the system and thence back to the rear between a frame 105 on which the electrical and mechanical components are mounted and a cover assembly 111 which surrounds the frame. The construction and mounting arrangement of the rotor and stator enable the DC brushless motor to generate the torque needed to drive the discs and the blower wheel, while the blower wheel in combination with the duct assembly provide a very efficient arrangement for producing a flow of air for cooling purposes. <IMAGE>

Abstract: 866,400. Gyroscopic apparatus. VICKERS AIRCRAFT HOLDINGS Ltd. June 4, 1959 [July 2, 1958], No. 21247/58. Class 97(3) A gyroscope is held caged whilst jets of fluid under pressure bring it up to operational speed and on cessation of the pressure fluid supply the gyroscope is decaged. The pressure fluid supply may consist of a container having air or other gas in compression or, as shown, comprises a gas generator cartridge 19, Fig. 3, which is mounted on a gas distributing block 15 and is ignited electrically through leads 20. The gases pass through a perforated wall 221, acting as a filter, of a member 22, through a chamber 17 and ducts 16 to jet nozzles 14, Fig. 1, so as to impinge on a pair of turbine blade rings 111 on each rotor 11. As shown, two gyroscopes are provided, each comprising a rotor 11 mounted in inner and outer gimbal rings 12, 13 which are caged by opposing faces 151 and sides of the limbs 152 of block 15 engaging the gimbal rings 13, 12, respectively. Balls 25 in bores 231 of a fixed sleeve 23 normally lock member 22 in block 15 against movement, but the gas generated by cartridge 19 forces a piston 26 outwardly until its tapered end engages a valve seat 234 on sleeve 23 and allows the balls 25 to enter a neck 261 in the piston 26. The block 15 and member 22 are now free to move but the gas pressure prevents movement occurring. When the gas pressure falls, springs, not shown, acting on the block 15 slide it to the left, Fig. 3, and the gyroscopes are uncaged. In a modification the balls 25 project into an annular groove formed on the inner wall of the member 22.
