Abstract: 988,198. Intermittent feed mechanisms for cine cameras. A. E. COUTANT, and J. MATHOT. March 1,1963 [July 30, 1962], No. 8251/63. Heading G2E. The cine camera intermittent film feed mechanism comprises a plot claw 1 which engages a perforation 2 in film 3 and performs a vertical and transverse reciprocating motion whereby film 3 is advanced in increments of one frame height, a registration claw 4 moving transversely and engaging another perforation 5 immediately after the film has been advanced to hold the film stationary while the exposure is made. Claw 4 reciprocates transversely about pivot pin 6 as its forked end 10 follows the motion of member 9 having a circular aperture engaged by eccentric cam 8 on rotary shaft 7. Pilot claw 1 pivots freely at pin 11 eccentrically mounted on disc 12 driven by shaft 7, and is urged towards film 3 by spring 13 freely engaging pin 14 on the claw. The angular position of claw 1 is controlled by the engagement of pin 18 with upper arm 17 of a two-armed lever 15 pivoted at 16 whose lower arm engages pin 19 and whose angular position is therefore decided by the transverse position of claw 4. As shown in Fig. 1 pin 18 in moving over the end of lever 17 allows claw 1 to enter perforation 2 so that its lower, inclined edge engages the film smoothly and noiselessly. Claw 1 then moves downwards transporting the film as pin 18 moves back down lever 17 as in Fig. 4. At the end of this film transporting stroke, lever 15 is pivoted anti-clockwise to disengage claw 1 while claw 4 enters perforation 5 to arrest the film. The cycle is then repeated.

Title: Improvements in and relating to the production of nitrogen-containing atmospheres
Inventor: WHEELEY EDWARD ALFRED
IPC: C21D1/76
Filed: 1953-03-26
Abstract: Nitrogen is produced by introducing ammonia and primary air in a molecular ratio of not less than 4:3 into the top of a preheated nickel catalyst bed in a chamber 1 via inlets 11 and 12, introducing secondary air into the bottom of the bed via inlet 13, and allowing the product gas to pass via a grid 4 and an annular space between the chamber 1 and an outer open top chamber 2 to an exit pipe 14 so as to effect heat exchange with the upper portion of the catalyst bed.  The catalyst may be in massive form, e.g. as grannules, sponge, or pellets, or may be supported on a carrier such as pummice, silica, alpha alumina, or Kieselguhr.  A wire gauze dome 17 prevents catalyst passing into pipe 13.  The temperature at the bottom of the catalyst bed may be controlled by introducing cooled product gas via a pipe 18.  A gas burner for initially heating the catalyst bed may be introduced through a pipe 15.

Title: Improvements in or relating to a safety means for use in a system for controlling a fluid actuated device
IPC: F16K17/00
Filed: 1954-03-23
Abstract: 744,581. Machinery safety devices. ROSS OPERATING VALVE CO. March 23, 1954 [March 27, 1953], No. 8437/54. Class 80(4) In a fluid control system for a press or other device wherein a fluid motor 13 is. controlled by two spaced hand-operated valves 12 so that both hands of an operator must be occupied in starting the press &c., a safety valve 11 is included in the system and is responsive to lack of synchronism between the valves 12 so that it one of these is tied down the motor cannot be operated. In the construction shown the valves 12 comprise pilot valves actuating a master valve 14 for an expansiblechamber motor 13, the alternate supply and exhaust of air pressure in the conduit 22 which operates the valve 14 causing alternate connection of motor 13 to a supply 23 and exhaust 24. The conduit 22 is connected to a central chamber in the valve 11 which is connected by parallel lines 17 and the two valves 12 either to an air supply conduit 15 or to exhaust 16. The valve 11 comprises a pair of slidable valve members 26 which are normally pressed apart by a central spring to engage seals 28. Their inward movement is limited by abutting of their inner ends. The periphery of each valve 26 has cut-away portions so that if either valve 26 is moved inwardly the central chamber, and thus the conduit 22, is connected to exhaust vents 32. Housed within each valve 26 is a spring-loaded ball of a size such that sufficient air may pass to operate the valve 14, the pressure on each ball tending to move it inwardly against a seat in the valve 26. When the pressures on the two balls are equal, their inward movement is prevented by a central pin 43 which extends between the balls and is slidable in the inner ends of the valves 26. Should one valve 12, e.g. the left hand valve, be tied down in the "supply" position, then when next the other valve 12 is moved to " exhaust." the balance of forces on the pin 43 will be removed and the left hand ball will be moved against its seat, causing a build-up of pressure at the outer end of the left hand valve 26 which will force it to the right, thereby exhausting the central chamber through vent 32. Subsequent movement of the right hand valve will not then affect the valve 14, since the central chamber will remain vented. To reset the safety valve 11, both valves 12 must be moved to " exhaust." A similar train of events would exhaust the central chamber should one valve 12 be tied down in the "exhaust" position. It is stated that (1) the valve 14 may be arranged to stop in some position other than the closed position when conduit 22 is exhausted: (2) the valves 12 may operate two master valves for a double-acting motor; and (3) the valves 12 may serve as direct-operating valves without a master valve.

Title: A telephone system for two-party connections
IPC: H04Q5/24
Filed: 1954-03-24
Abstract: 757,943. Automatic exchange systems. LICENTIA PATENT-VERWALTUNGS-GES. March 24, 1954 [March 30, 1953], No. 8606/54. Class 40 (4). In a system having a switching centre for connecting either of two subscribers to an exchange line, arrangements are made for disabling one subscriber without affecting the other. As described in Specification 749,120, the switching centre is provided with retentivity relays for establishing connections to the respective subscribers, one subscriber calling by momentarily earthing wire La and the other by earthing wire Lb, while release is effected by applying battery to the opposite leg, to which the release winding of the retentivity relay is connected. Thus since the calling wire for one subscriber is the release wire for the other it must be arranged that disabling one party from calling does not interfere with the release of the other party. As shown, Fig. 1, when subscriber No. 1 calls, earth is applied over his retentivity relay to wire La to bring up R1 over winding 5/6 extending the line loop to a preselector VW wherein a further circuit in shunt with the operating circuit for R1 1 increases the current in line La to bring up the retentivity relay in the switching centre. This relay disconnects itself and the other subscriber, and connects the calling subscriber's loop to the exchange. The preselector then starts to hunt and when it moves off normal it opens the circuit of an opposing winding of relay T permitting it to operate and lock up R1. When the connection is released the preselector homes to release T and R1 follows. Release of T connects battery over R2 to the wire Lb, thereby releasing the operated retentivity relay at the switching centre. In the case of an outgoing call from a final selector LW, relay T is operated over the C wire and potential is applied either to the La or Lb wire according as the selector is set to terminals a1, b1 or a2, b2 to operate the appropriate retentivity relay. If one subscriber, say subscriber No. 1, is to be disabled the corresponding break jacks are operated and an opposing winding 1/2 of R1 is thereby inserted so that a calling condition on wire La does not operate R1. The resistance of this coil is so arranged, however, that sufficient current can pass through the two coils of R1 in series to de-energize the retentivity relay of subscriber No. 2. In a modification, Fig. 2 (not shown), the coil 1/2 is replaced by a resistance so dimensioned that a line relay will not operate in series with it, but is sufficiently low to provide adequate de-energizing current for the retentivity relay. In a further modification, Fig. 3 (not shown), the line relay is shunted by a resistor which, however, does not stop it operating, the circuit of the relay, but not that of the resistor, being opened by the break jack. The resistor then carries the de-energizing current for the retentivity relay.
