Title: Improvements in or relating to printing telegraphy
IPC: H04L12/54
Filed: 1951-04-10
Abstract: 700,998. Actuation of switches. TELETYPE CORPORATION. April 10, 1951 [May 10, 1950], No. 8284/51. Class 38(5) [Also in Groups XXIV and XL(b)] Sequence-switches and a switch for closing alarm contacts after a predetermined delay, for use in a telegraphic interconnection system (see Group XL(b) are actuated by ratchets controlled by constantly-rotating shafts. Sequence switches. Six sequence switches are operated from a common continuously-rotating shaft under control of individual magnets. Fig. 19 shows the mechanism for one such switch. A bail 641, common to all the switches, is oscillated between the full-line and dotted-line positions by an eccentric 636 on the shaft 609 and co-operates with two pawls 642, 643 connected together by springs 647, 648 and acting on a ratchet 644 carrying the contact-controlling cams 646. With the individual control-magnet 649 de-energized, pawl 642 is prevented by armature 651 from moving sufficiently to the right to drop on to the next tooth of ratchet 644 but, at each energization of the magnet, pawl 642 drops on movement of bail 641 to the right and advances the ratchet a halfstep on the next movement to the left, and pawl 643 is then effective to move the ratchet a second half-step when the bail moves again to the right. Delayed-alarm switch, Fig. 32. Magnet 633, when operated, withdraws a locking projection 826 from a lug 824 on a driving pawl 817 associated with a ratchet segment 821. Eccentric 816 on continuously-rotating shaft 609 reciprocates pawl 817 so that, after a predetermined time if magnet 848 has not operated, ratchet 821 operates lever 836 to close contacts 839 connected to an alarm 842. If magnet 848 operates within the predetermined time its armature withdraws the driving pawl 817 and holding pawl 832 releasing the ratchet segment.

(iv)] A flame-proof lighting fitting shown in Fig. 1 comprises a cast iron or brass connecting box 1, a conical casting 3 secured to the underside of the box 1, a well glass 8 secured by a ring 5 to the rim of the casting 3, and a diffusing glass screen 12 resting on the rim of the well glass and extending slightly below the filament of the lamp 7. The screen 12 is formed preferably on its outer surface with horizontal prismatic rings 13 which deflect downwardly light emitted at small angles below the horizontal to limit the intrinsic brilliance of the source. The well glass may be formed with vertical diffusing prisms 14. Cushioning material 11 may be interposed between the screen on the well glass which is cemented between the ring 5 and a backing ring 9. Fig. 2 shows another construction in which a prismatic or translucent glass reflector 15 rests on a shoulder 16 in the well glass 8. The well glass 8, reflector 15, holding ring 5 and backing ring 17 are attached to the housing 19 by a chain 20 by which they are supported when renewing the bulb 7. In another construction a reflector around the bulb is supported by a metal gallery carried by the conical housing. In a further construction, downwardly-reflecting prisms are formed on one side of the well glass and diffusing screens on the other, or the upper zone of the well glass is coated with a translucent enamel. All forms permit free air circulation in the fitting.

Title: Improvements in or relating to stabilising or steady-wheel devices for single track motor vehicles
IPC: B62D61/02
Filed: 1940-05-09
Abstract: 541,145. Safety-wheels for motor-cycles &c. WESTCOTT, J. S. May 9, 1940, No. 8369. [Class 136 (i)] The safety wheel 12 is mounted on a frame 9 pivoted on a spindle 5, and may rise and fall freely except when upward movement is checked by a one-way clutch device actuated by the drivers foot. The device comprises a sleeve 5 keyed to the spindle S, and a loose brake drum 7 surrounded by a coil spring 8 anchored at one end at 9<SP>1</SP> and having its other end connected to a foot pedal 13. The sleeve 5 has recesses containing balls 6. Normally the spring is loose on the drum and as the frame 9 rises i.e. pivots anticlockwise, the balls drive the drum anticlockwise, but when the driver depresses the pedal he tightens the spring on the drum, which is thereby rendered immovable and cannot be driven by the balls; the frame is thereby prevented from rising, but may fall freely. Stops 14 limit the upward movement of the frame 9. A spring 15 supports the frame. The foot pedal may operate indirectly, as by rods and levers or Bowden mechanism. There are two wheels 12, one on each side of the machine.

Title: Apparatus for receiving orders and the like
IPC: G07F17/40
Filed: 1958-03-20
Abstract: 825,274. Coin-freed sound recording apparatus. BECH, T. March 20, 1958 [March 26, 1957], No. 8933/58. Class 27 Coin-freed apparatus for receiving orders for goods comprises a microphone 3 connected to a sound recording and reproducing device, which is preferably a separately installed tape recorder, means 26 for delivering receipt cards 13 from a magazine 15 and two push-buttons 29a, 29b connected by a lever 27 with an overcentre actionspring 28 so that they are operable in sequence to switch on the recorder and subsequently to deliver the receipt. A coin accepted by a tester 48 50 falls into a holder 25 connected to the push-button 29a and when the pushbutton is pressed in the edge of the coin depresses a locking catch 24 so that the holder can move rearwardly to operate a switch 21 to close the circuit for the recorder and for a signal lamp 6. When the order has been spoken into the microphone, the other push-button 29b is pressed and operates the card delivery means 26 so that a card 13 is pushed off supports 70 to a trough 30 covered by a weight- or spring-loaded flap 31 while the lever 27 returns the push-button 29a to initial position and the switch 21 switches off the recorder and signal lamp. The last card in the stack is turned at 90 degrees to the others so that it is clear of the supports 70 and, when the second last card has been pushed off by the means 26, it will fall to the trough 30 when the push-button 29a is operated and causes withdrawal of the means 26. Operation of the push-button 29b (and return of the push-button 29a) is then blocked by a weight 14 which pressed the stack of cards downwards. The time during which the recorder is switched on may be controlled by a time-limit relay. Coin testing. An inserted coin is tested for diameter and thickness between upper and lower inclined and grooved runways 48, 50. If too small in diameter, the coin loses the support of the upper runway and falls sideways into the card delivery trough 30 and if too thin it tilts sufficiently in both runways to be held up by side plates 52. Coin clearing and returning. A coin held up by the plates 52 is released by the de-energization of a magnet 9, allowing a spring 53 to lift the upper runway 50. The magnet is normally energized but is de-energized by operation of a coin return button 11, to return a faulty coin, or by failure of the current, or by the switch 21 when the push-button 29a is depressed so that further inserted coins are returned if the recorder is in operation or if the magazine is empty.
