Title: Improvements in and relating to air pressure gauges
IPC: G01L17/00
Filed: 1925-12-22
Abstract: 254,194.. Hallstead, L. A. Sept. 22, 1925, [Convention date]. Pneumatic-tyre pressure-gauges.-Relates to gauges of the kind in which the air pressure is adapted to elongate a rubber sleeve to which is attached a pressure-indicating element moving over a scale, and consists in providing means to assist the air pressure in moving the sleeve at low pressures and also means to prevent distortion of the rubber sleeve at excessively high pressures. The nozzle 4 having a plunger 6 for opening the tyre valve is adapted to rotate in a bushing 3 in the end of the gauge casing 1. The passage 12 from the nozzle opens into a recess 2 adapted to receive the gauge proper. Into the right hand of the recess 2 is screwed a tubular bushing 14 having a reduced portion 15 and a still slightly more reduced portion 16. A sleeve 20 inside the casing 1 is screwed internally to receive a plug 21 which is reduced at the left hand 22 to the same size as the portion 15. The portion 16 is adapted to receive one end of a rubber sleeve 23, the other end being drawn over and sealed by a plug 24 contacting with the part 22. A spiral spring 25 surrounds the rubber sleeve and is secured at the ends to the parts 16, 22. A spiral spring 26 surrounding the spring 25 is attached at the left hand to the bushing 14. The end of the sleeve 20 can be seen through a slot 27 in the casing which is at this point provided with a scale. A valve 29 is provided in the recess 19 the stem 31 of which extends nearly to the plug 24 when the valve is in the inoperative position, and is provided with a head 33. A tube 32 surrounding the valve stem and secured to the plug 24 extends to the left, the end being turned in as shown. A spring 35 normally keeps the valve open. In use, the nozzle is pressed against the tyre valve and the air enters the gauge extending the rubber sleeve. The spring 26 bears against the indicating sleeve 20 and assists the air in acting in opposition to the stronger spring 25. This enables the gauge to be used for low-pressure balloon tyres with considerable movement of the index. At higher pressures the sleeve moves beyond the influence of the spring 26 and the stronger spring 25 exerts its full effect. At still higher pressures approaching the point dangerous to the gauge the inturned head of the sleeve 31 engages the head on the valve stem and closes the valve 29.

Title: Register apparatus
IPC: H04Q3/54
Filed: 1972-07-13
Abstract: 1400172 Reading out counters WESTERN ELECTRIC CO Inc 13 July 1972 [16 July 1971] 32780/72 Heading G4D [Also in Division H4] To read out a counter it is advanced from its storage state through a predetermined state, such as zero, to a final state, related to the storage state, by control pulses, the number of pulses used to advance the counter from the predetermined to the final states representing the reading of the counter. In a telephone system a calling station alerts a common control 7 which selects an idle register (1-N) to which dialing pulses are then fed. The first group of dialing pulses is fed into a thousands counter 41 by a pulse detector 6 which also alerts a read control 2; at the end of the group, read control 2 sends high speed pulses to counter 41 to cause it to cycle through all its states. As the counter 41 passes zero the high speed pulses are passed to line DRM1. The next group of dialing pulses is diverted to the hundreds counter (42) and then rapidly read out via line (DRH1). Similarly the low speed dialing pulses for the tens and units digits are converted to high speed pulses on lines (DRT1) and DRU1. This arrangement may be used with the telephone switching system of Patent 1,108,701.

Filed: 1931-12-03
Abstract: 393,613. Protective cut-out arrangements. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, WILLIS, F. B. and WESTELL, E. P. L., c/o General Electric Co., Ltd., Stoke, Coventry. Dec. 3, 1931, No. 33507. [Class 38 (v).] A protective cut-out system in which the control between the ends of the protected section is effected by impulses of high-frequency A.C. derived from a continuously maintained thermionic generator, has intermediate means such as an amplifier inserted between the oscillation generator and the channel of communication in such a manner that the constants of the oscillatory circuit are not affected during the application of the oscillations, oscillations of the correct frequency being instantly applied to the channel of communication on predetermined circuit conditions arising. In the arrangement shown in the Figure of the control apparatus at one end of a protected section having a transmitter I and receiver 2 the transmitter comprises a continuously energized oscillator valve 5 which supplies an amplifier valve 6. A condenser 46 in the anode circuit of the amplifier valve 6 is normally short-circuited at contacts 10, 11 of a relay 9, but when this relay is energized in response to an overload current in a predetermined direction in the protected section, the short-circuit is removed from the condenser 46 and the output of the valve is fed through a transformer 8 to a toned circuit 4 through which the H.F. oscillations are superimposed on the line section at a point 26. When the superimposed currents are received at the remote end a receiver similar to that shown at 1 is energized through H.F. currents in the toned circuit 4 and a negative potential is produced at the grid of the valve 15 reducing the current flowing in the coil 18 of a differential relay 14, and thus causing the relay to close its contacts 17. By this means the tripping of the circuit-breaker at the adjacent end of the section is prevented so that in the case of a " through " fault no disconnection of the section takes place. The receiver at the end from which the control currents are sent, is disconnected from the tuned circuit 4 by a relay 47 energized in series with the transmitter control relay 7. Specification 378,006 is referred to.
