Title: Improvements in or relating to orthopedic pads or socks for boots and shoes
IPC: A43B7/22
Filed: 1919-07-02
Abstract: 141,574. Plummer, A. B. July 2, 1919. Boots and shoes; foot-arch supports.-An orthopµdic pad for boots and shoes comprises a sock 7 having a centrally-arranged raised pad 14 situated just behind the tread of the foot, and a second pad occupying the heel portion of the sock and extending forwardly on the inner side of the foot to the line 13. The heel pad is wedge-shaped the thick end of the wedge being along the line 8 at the inside of the foot, and the thin end along the line 9 at the outside. This pad is diminished in width where it passes under the instep, as shown at 11, and at the extreme forward end a projecting tongue passes on one side of the pad 14 to the line 13. This pad may also be bevelled at the rear, as shown at 10, and at the projecting tongue, which slopes away to a fine edge at the line 13. The centre of the pad 14 is as high as the thickest part of the heel pad, and it slopesaway on all sides from the centre.

Title: Electrical control arrangements for textile machines
IPC: G05B19/14
Filed: 1970-04-07
Abstract: 1310908 Programmed control UNIVERSAL MASCHINENFABRIK DR RUDOLF SCHIEBER KG 7 April 1970 [14 April 1969] 16523/70 Heading G3N An electrical control arrangement, responsive to movable programme carriers, for textile machines, is provided with transfer devices which combine in groups to control impulses, derived from switch contacts actuated by the carrier. Each group of control signals being arranged to initiate one of a plurality of logically linked control functions. As shown, for a case in which only one control function can occur at a time, signals from switch contacts 24-26, actuated by the control carrier, are permutated together with a signal from a switch contact 27, synchronized with the movement of the knitting machine, at the inputs of gates 8-23 providing specific control outputs. A saving of programming space on the carrier can be effected by connecting to separate gates 8-23 (a) feeding devices to be simultaneously actuated through amplifiers, Fig. 1 (not shown), and (b) a motor reversed through storage devices by limit switches, Fig. 3 (not shown).
Patent GB-581149-A (GB)
Title: Telephone recorder-repeater system
IPC: H04M1/65
Filed: 1943-10-11
Abstract: 581,149. Automatic exchange apparatus. NEWTON, E. P. (Lesavoy, L.). Oct. 11, 1943, No. 16633. [Class 40 (iv)] In a message centre provided with sets of recording and reproducing apparatus, preferably of the telegraphone kind, when' the number identifying a particular subscriber is dialled, a telegraphone is allocated to that subscriber for a predetermined time during which it is available to any subscriber dialling the same number and thus serves as a medium of communication between the particular subscriber and other subscribers. The telegraphone is conditioned for recording or for reproducing in response to an extra dialled digit. A calling line is extended over a line finder to a selector 12, having each of its outlets 13 connected to a hunting switch 14. When the selector is set on a particular outlet in response to dialling, the switch 14 hunts in the usual manner for an idle telegraphone, and the calling line is extended to wires 46, 47 bridged by a slowrelease holding relay 48 and an impulse relay 49, both of which energize. The subscriber dials a further digit 1 for recording or 2 for reproducing, and this is repeated by relay 49 to a switch 60 which connects up relay 66 or 67 and immediately restores. For recording, relay 66 energizes relay 71 which connects wires 46, 47 through an amplifier 93 to the recording head 99 of the telegraphone 100 and starts the feed motor 101 for the tape, this condition being maintained until relay 48 is released by the subscriber hanging up or until relay 78 is energized. For reproducing, relay 67 energizes relay 78 which extends wires 46, 47 to the output of an amplifier 115 and connects up the motor 101 to wind the tape back to its starting position, whereupon a sleeve 126 threaded on the motor shaft closes contacts 127 to energize relay 129 to reverse the direction of the motor, the pick-up head 121 being now connected to the amplifier 115. Relay 78 remains operative until relay 48 is released or until relay 71 is energized. In case a subscriber hangs up before the reproduction is complete, the motor circuit is maintained by a voice-current relay 155 in the output of the amplifier 115 to drive the tape to the proper position for the next recording. It will be noted that a subscriber may change from recording to reproducing or vice versa by dialling the appropriate digit without hanging up. The telegraphone remains attached to the switch 14 until a clock-driven camshaft 145, which is started by the first operation of relay 48, has made a complete revolution, which may take 24 hours, for example. The release magnet 26 of the switch 14 is then energized and a magnet 154 is operated to erase the record as the tape is returned to its starting position.

Abstract: 977,704. Feeding sheets. LINOTYPE & MACHINERY Ltd. May 3, 1963 [May 3, 1962], No. 16990/62. Heading B6B. Pneumatic suckers of the piston and cylinder type for separating sheets one at a time from a pile and forwarding them to sheet feeding means, is characterized in that the piston is provided with a groove to receive locking means which engage therein to lock the piston in a raised position within the cylinder during substantially horizontal movements of the sucker and to be automatically unlocked to allow the piston to drop to a lower position when the sucker is in a correct position to commence a sheet feed cycle. The piston 3 carrying a sucker foot 9 and slidable in a cylinder 1, is provided with a peripheral groove 12. The cylinder is provided with a bore 13 extending tangentially to the piston in which a spring blade 14 is mounted. In operation, suction is applied to the sucker via a tube 5 whereby the top sheet of the pile is gripped by the sucker foot. The piston is retracted due to the vacuum created in the chamber 2, to separate the top sheet from the pile. The sucker is moved horizontally to forward the sheet to feeding means, whereby the spring blade 14 is disengaged from a fixed part 18 of the machine frame so that said spring blade moves into latching engagement with the groove 12 to hold the piston in its retracted position. The piston is released and allowed to fall when the sucker is positioned once more above the pile with the spring blade in engagement with the fixed part 18. The spring blade may be replaced by a latch projecting through a hole in the inner wall of the cylinder.

Abstract: 777,959. Winding golf ball cores; tension arrangements ; stop motions. DUNLOP RUBBER CO., Ltd. June 7, 1955 [June 11, 1954], No. 17167/54. Class 120 (2). A golf ball winding machine has a pair of cylindrical core supporting rollers and a pair of concave rollers mounted parallel to the cylindrical rollers and bearing upon the core but movable away from the cylindrical rollers as the ball increases in size. Both cylindrical rollers are positively rotated and oscillated, the oscillating means including eccentric sheaves surrounded by straps and associated by linkages to the rollers. Helical gears 18, Fig. 4, on a shaft 19 drive the shafts 11 of the cylindrical rollers 10 through helical gears 17. Eccentric sheaves 21 are also mounted on the drive shaft 19 and are surrounded by straps 22 directly connected to rods 23 linked to caps 28 containing roller bearings 28a and securing means for the shafts 11. Each roller 10 is covered with a layer of rubber 12 and the concave rollers 29 are also rubber-covered. The rollers 29 are mounted in a supporting member 30 attached to a plunger rod 31 provided at its upper end with cup washers 32, 33 forming a piston in an air cylinder 34. A spring 35 urges the rollers 29 downwardly. Air may enter the cylinder 34 at predetermined intervals to urge the rollers 29 intermittently against the core to compact the windings. In order to insert a fresh core, a push button 41, Fig. 1, is pressed, allowing air to enter the cylinder 34 below the piston, thus raising the rollers 29. In operation, rubber thread 90 is drawn from a reel 91 and around a freely rotatable tensioning pulley 66 against which a rubber belt 69 is pressed. The belt 69 is stretched between stationary pins 70, 71 that are adjustable to alter the pressure of the belt on the pulley 66. From the tensioning device, the thread passes over the pulley 68 of a stop motion. So long as the pulley 68 is depressed a microswitch plunger 78 is depressed to maintain the driving motor circuit. When the core has reached a predetermined size, a pin 81 attached to the member 30 depresses the plunger 84 of a second microswitch to stop the motor.
