Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1923-11-13
Abstract: 222,347. Coventry Automatic Telephones, Ltd., Collyer, J. E., and Wilman, C. W. Nov. 13, 1923. Automatic and semi-automatic exchange systems; metering systems.-In a Strowger &c. connector, the sluggish relay that switches over the impulse circuit on its relapse after the tens digit, is energized again to complete the ringing circuit, and is released on the operation of the 'back-bridge relay to control the duration of a booster metering impulse. Means are provided to ensure the complete release of the connector. The invention is described in a two-digit system. Line switch A and connector B. In response to a call over the line 12, 13, line relay 1 grounds the normal terminal 10 to energize the stepping magnet 3. At the end of the stroke, magnet 3 releases itself and the wipers take a step. The stepping action continues until wiper 6 finds an ungrounded terminal, whereupon switching relay 2 pulls up and extends the talking and c-wires and relay 1 falls back slowly to give time for a holding ground to be returned from the connector. In the connector, line relay 101 pulls up, followed by release relay 102 and relays 103, 104. The tens digit is repeated to vertical magnet 119 and at the end of the digit, vertical springs 117 having changed-over relay 103 falls back and switches the impulse circuit to the rotary magnet 120. Busy test and signal and control of ringing current. If the line is busy, relay 105 pulls up, and when relay 104 falls back shortly afterwards (owing to the change-over of rotary springs 118), busy tone and flash are connected from 135 to the upper talking wire. If, on the relapse of relay 104 relay 105 is not operated, switching relay 106 is energized over its upper winding and the wanted cut-off relay. Relay 106 locks over its lower winding which it normally short-circuits to make it slow to energize, short-circuits its upper winding and re-energizes relay 103 which completes the ringing circuit from 147 over ring-trip relay 107. A high-frequency tone superimposed on the ringing current leaks back over condenser 148. Completion of connection, metering. When the called party replies, relay 107 pulls up, locks itself and extends the called loop to operate back bridge relay 110 which releases relay 103. In the interval between the energization of relay 110 and the relapse of relay 103, booster battery D is connected over the C-wire to the meter 20. Release. When the calling party hangs up, the relapse of relays 101, 102 energizes release magnet 152 and releases both cut-off relays and relays 106, 107, 110. The line-switch A is restored to normal under control of wiper 9. The locking circuit of relay 107 is controlled by relay 106 which releases quickly. This arrangement ensures that the sluggish relay 107 releases even if the connector is seized again immediately after the release of relay 102. If only the called party hangs up, the attendant is notified by the glowing of lamp 153. Specifications 224,308 and 224,692 are referred to.

Filed: 1966-06-27
Abstract: 1,080,860. Heat transfer devices. GENERAL MOTORS CORPORATION. June 27, 1966 [July 20, 1965], No. 28607/66. Heading F4S. [Also in Division F1] A gas turbine engine comprises a plurality of turbine inlet nozzle guide vanes, each guide vane having a closed-ended tube extending therefrom to a region which is exposed to flow of air from the compressor, the tubes being disposed in a circumferential assembly. A porous material is disposed within the tubes and guide vanes and a heat exchange medium substantially fills the tubes and guide vanes, a portion of the heat exchange medium being in the liquid phase and saturates the porous structure the remainder being in the vapour phase, whereby a closed system is provided which when the engine is working acts to transfer heat from the guide vanes to the compressor discharge air thus cooling the guide vanes. The engine in Fig. 1 comprises turbine inlet guide vanes 40 from each of which extends a tube 54, the tubes extending through the combustion equipment between the flame tubes 44 and the outer air casing 46 into the diffuser section 42, the upstream ends of the tubes being closed. A guide vane 40 is shown in Fig. 3, the vane extending through a transition section 62 to the tube portion 54. The vanes are disposed between inner and outer walls 41, 43 which are contiguous with the walls 45 of the turbine inlet passage 47. The vanes 40, transition sections 62 and the tubes 54 are lined with a layer of porous material and a heat transfer medium such as sodium is disposed within each vane, transition section and tube assembly, the sodium being partly in the liquid phase and partly in the vapour phase, that in the liquid phase being contained in the porous material. In operation the vane portion constitutes an evaporator wherein the liquid sodium is vaporized, the vapour flowing towards the closed end of the tube where it is condensed by the flow of relatively cool compressor discharge air, the liquid sodium passing back into the porous material where it flows back to the vane or evaporator. The guide vanes are thus cool and at the same time the air passing to the combustion equipment is preheated.

Title: Improvements in or relating to measuring instruments and indicators
IPC: G01L3/10
Filed: 1921-11-01
Abstract: 192,749. Moullin, E. B. Nov. 1, 1921. Tell-tale apparatus.-Torsion or other angular movement of a shaft is measured by the variation in the reluctance of a. magnetic circuit, two elements of which are supported at positions between which the relative angular movement takes place. Two saddle pieces 11, 12 are fixed to the shaft 10 at points some distance apart. The saddle piece 11 supports a U-shaped laminated magnet 13 on which is mounted a coil 14. The saddle piece 12 carries an arm 15 extending longitudinally of the shaft to the piece 11. A laminated armature 16 separated from the magnet 13 'by a small air-gap 17 is carried .on a rod 18 passing through a bracket 19 carried on the saddle piece 11, the rod being pressed to the right, Fig. 2, by a spring 20. The end of the rod engages a coned screw passing through the arm 15. An alternating current is supplied to the coil 14 from an alternator 22 through slip-rings 24. When the shaft is transmitting power, the air-gap 17 is reduced and the variation in the current through the coil 14 which is indicated at the ammeter 23 is a measure of the relative angular rotation between the points at which the saddle-pieces are secured. The ammeter 23 may give direct readings of the length of airgap and consequently of torsion angle. When required to indicate power, an alternator excited by a direct current permanent magnet generator driven by the shaft may be used. Instead of modifying the generator, a current measuring device may be used which gives indications proportional to the product of the current in the winding 14 and the speed of the shaft. The ammeter may measure the root-mean-square value of the current, or an instrument of the oscillograph type may be used. The magnet core and. armature may be mounted in saddles of different sizes for fitting to shafts of different sizes. For measuring large angles, the pole faces of the magnet core may be arranged coaxially with the axis of rotation of the moving part, the armature in this case being tapered to obtain variation in the size of air gap.
