Abstract: 1,050,556. Magnetic pulse storage apparatus. AMP INCORPORATED. June 28, 1965 [July 17, 1964], No. 27235/65. Heading H3B. In a shift register, Fig. 4 (not shown), a storage core has the configuration shown in Fig. 1a, legs 20, 26, 28 and 30 having half the cross-sectional area of legs 22 and 34. As shown in Fig. 1a the core is in its clear (binary 0) state. If input winding 36 is energized, the flux in leg 20 is reversed to set the input of the core in its binary 1 state, Fig. lb (not shown). Windings 40 and 38 are energized in that order to transfer the binary 1 to the output 16, Figs. 1c and 1d (not shown). If then the external advance winding 42 is energized an output pulse is induced in the output winding 44 and the core is returned to its clear state. Input winding 36 may be energized simultaneously with the output pulse. If the input winding is not energized to set the core the other windings have no effect. Winding 40 may have a loop through aperture 18, Fig. 3 (not shown). A respective non-destructive read-out winding may thread each aperture 54. Aperture 18 may be rectangular.

Abstract: 1,228,423. Moulding machines. SHERWINWILLIAMS CO. 5 April, 1968 [10 April, 1967], No. 16552/68. Heading B3F. A jolt foundry moulding machine comprises a moulding table 6, a ram 29 and an air spring operative to drive the ram against the table 6 to provide a jolt strike, the air spring comprising a plenum chamber 63 supporting both the table 6 and ram 29. A piston 9 supports both the ram and the table, but, before the piston 9 raises the table 6 to press a flask thereon against a presser head 5, the sand in the flask is jolted. To effect this, air is supplied by a servo-valve 98 through a conduit 60 to the chamber 63 so that the ram moves upwards. The table also moves slightly upwards but stops when the servo-valve closes on reacting a fixed pressure. The ram 29 opens a poppet valve 38 and air supplied from valves 124 or 125 through conduit 47 forces the ram 29 downwards. As the ram 29 descends the poppet valve 38 closes and the table 6 rises. The rising movement is sensed by an arm 106 which controls the servo-valve 98 and opens a restricted passage in the servovalve to allow air to escape slowly from the chamber 63. The ram 29 falls until the air above it vents to the atmosphere through various passages (not shown). The resulting pressure in chamber 63 is greater than that above the ram 29, so the ram is forced upwards and the table falls to provide the jolt-strike. When the table 6 reaches the bottom of its stroke, the arm 106 closes the valve 98 to seal chamber 63. At the same time, the pressure in chamber 63 can be increased. Jolting continues as long as valves 124 or 125 are open. After jolting, the table 6 is raised against the head 5 to press the sand in the flask. Air is supplied to a conduit 113 of the valve 98 to override the arm mechanism 106, enabling jolting to take place while pressing. A valve 126 supplies air to a vibrator 127 to aid stripping of the pattern from the flask.

Abstract: 1,257,903. Indexing; machine tool details. GLEASON WORKS. 9 Jan., 1970 [3 March, 1969], No. 1187/70. Heading B3B. A method of indexing a work table 20 comprises effecting mechanically an initial indexing movement, taking a reading of the position reached thereby and effecting further corrective movement to bring the table to its final position accurately. The initial indexing movement is derived from a motor 136 the drive period of which is controlled by limit switch LS7 so as to rotate an index cam 150 through a predetermined angular movement which is transmitted through gearing 68 and clutch 126 to a drive worm 26 which engages a worm wheel 24 coaxial with the table 20. After completion of the initial movement a toothed clutch 66 is engaged by hydraulic actuating means 64 to lock the table together with the indexing drive. An optical measuring device 218, 222 utilizing the Moire fringe principle measures the precise position reached and serves, by means of the automatic control head 140 to initiate a corrective axial movement of the worm 26 (without rotation) to bring the table into its final position. For this purpose the worm 26 is mounted on a bracket 30 arranged for limited sliding movement and the axial movement is effected by controlled transverse displacement of a wedge element 232 driven from a motor 216. In actual operation motor 216 operates simultaneously with motor 136 in the initial indexing stage to move the worm 26 axially in a direction such as to ensure that further indexing movement of the table will always be required and this is then effected by displacement of the worm 26 in the opposite direction. Backlash preventing.-To prevent any errors arising in the position of the table due to backlash in the worm/wormwheel drive 26, 24 a further worm 28 is arranged for synchronous rotation at right angles to the worm 26, the respective mounting brackets 30, 32 being connected by means of a bell crank lever 34 and hydraulic cylinder and piston means 56, 58. At the end of the initial indexing movement hydraulic pressure is admitted to the cylinder 56 so as to urge the brackets 30, 32 and thus also the worms 26, 28 axially apart thereby eliminating any backlash.
