Filed: 1947-10-13
Abstract: 659,862. Pulse discriminating circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 13, 1947, No. 14929/50. Divided out of 659,819. [Class 40 (vi)] In an analyzer for classifying pulses according to their amplitude, pulses are derived from the input pulses which have a longer duration and an extended portion whose amplitude is determined by the peak amplitude of the input pulse present at that time and each derived pulse gives rise to an output pulse in a channel appropriate to the peak amplitude of the corresponding input pulse during the extended portion of the derived pulse. Fig. 4 shows a pulse analyzer in which a sequence of short pulses, Fig. 3 (a) from, for example, a Geiger counter, are applied to the input 1 of a pulse generator G1 which produces output pulses of longer duration, Fig. 3 (b) having an amplitude proportional to that of the corresponding input. pulse. The derived pulse of Fig. 3 (b) is applied to an amplitude discriminating circuit D as described in Specification 659,819 to prepare one of the counting channels Cl ... C5 in depen. dence on its amplitude and is also applied to the pulse generator G2 which produces a rectangular switching pulse, Fig. 3 (c) falling wholly within the duration of the flat top portion of the derived pulse. The switching pulses are applied either by connection 2a to condition the discriminator circuit D to pass a pulse to the prepared counting circuit or via connection 2b to gate circuits K in .all the counting circuits to condition them all to enable a pulse to be transmitted to the selectively-prepared one. The switching pulse may be fed back to generator Gl via lead 7 to terminate the derived pulse of Fig. 3 (b).

Filed: 1972-03-30
Abstract: 1418901 Welding by fusion W H SIMON 15 March 1973 [30 March 1972] 14934/72 Heading B3R In gas-shielded arc welding, filler wire 5 is fed from a reel in an inert gas (e.g. argon) hermetically-sealed container to the arc through a device which is adapted to be secured to said container and comprising a pneumatically-operable valve normally spring-biased into a position in which it prevents passage, through the device, of filler wire and a surrounding envelope of shielding gas from said container. Closure of the valve enables transportation of the reel housing without losing its inert gas atmosphere. Further, air pressure to open the valve may be sequenced in accordance with a welding operation being performed. The device comprises wire and inert gas inlet and outlet sections 7, 8 and a piston 3. Wear-resistant, hard ceramic guides 15 are provided in coaxial passageways in said sections and piston. The valve comprises an 0-ring 13 contained in a chamber defined by a tapered bore 13 of the piston and the end of a valve seat 12 housed in an intermediate section 10 supported by the section 8. Normally, the piston 3 is rightwardly moved, as shown, by springs 17 (e.g. three) to inwardly press the 0-ring 13 into wire-detaining and inert gas sealing contact with the wire. When pressure air is admitted through a port 16, the piston 3 is leftwardly moved to allow wire and inert gas passage. In Figs. 3, 4 (not shown), damage to the O- ring, in the event of accidental excessive loading of the wire, is prevented by provision of a separate detent operable on the wire. Said detent comprises a lever (18) which is normally spring-biased to grip the wire between opposite sides of opposite ends of a bore of said lever and is moved to its wire-releasing position by the leftward movement of the piston 3.

Title: Improvements in or relating to prepayment meters
IPC: G07F15/08
Filed: 1936-06-05
Abstract: 473,707. Prepayment mechanism for meters. MEASUREMENT, Ltd., and CLIFFORD, C. F. June 5, 1936, Nos. 15723 /36 and 2617 /37. [Class 27] In a prepayment meter having stop rate mechanism, i.e. mechanism which varies the rate charged per unit after a certain quantity of commodity has been consumed, mechanism for resetting from the secondary to the primary rate comprises a synchronous or other suitable motor which winds up a spring connected to a part which, when it is turned by the spring, effects the change-over operation, the said part being released periodically and the actual time of termination of the periods being fixed by an adjustment in the mechanism. As shown applied to the step rate mechanism described in Specification 468,714, a synchronous motor, through a one-way driving device as described in Specification 455,442, rotates a shaft b, Figs. 2 and 4, having fixed thereto a disc c to which one end of a helical spring d, Figs. 7 and 8, is attached, the other end being secured to a loose disc e integral with a gear-wheel f. The disc e is held, during the winding of the spring d, by one end of a lever i, pivoted at j and controlled by a spring j<1>, engaging a peripheral gap h in the disc until the other end enters a peripheral gap g in the disc c. This releases the disc e, which is then rotated by the spring d, and the wheel f rotates a wheel k and a spindle in carrying a cam n which engages a roller o on an arm p to actuate a shaft q. An arm r with roller s on the shaft q engages and turns a heart-shaped cam t for resetting the step rate mechanism as described in Specification 468,714. The wheel k through a wheel 3 drives a spindle 4 having an escapement wheel 5 controlled by an escapement lever 6. This prevents overrunning of the wheels k, f due to the sudden release of the spring d. Indicators.-A barrel 7, having markings to indicate days of the week and divisions of time in each day, is mounted on an extension of the disc c. It is serrated on the inside and engaged by a spring tooth so that it can be turned only in one direction upon the extension. If a fixed pointer on the disc c is set to indicate on the barrel the desired time of resetting from the secondary to the primary rate and if then the disc and barrel are turned together until a pointer 9 on the fixed casing indicates on the barrel the day and time of installation or excitation of the motor, the resetting will always take place on the day and at the time indicated by the pointer 8.
