Title: Power supply protective terminal
Inventor: WANG KUAN CHUN
IPC: G06F1/26
Filed: 2009-09-17
Abstract: A terminal device for is connected between a power supplying apparatus and an electronic product and has a wire set 21, a non-active component 231 having a conductivity voltage threshold and a switch unit 25 that is activated to permit the output voltage to pass when the threshold is exceeded. Non-active component 231 may have a load resistor 233 and be a zener diode a forward biased diode, or plural light emitting diodes in series. The switch may be a relay (fig 5, 253) or an integrated circuit and be operated by a transistor 255 or a field effect transistor. A feedback signal (fig 9, 215) may command the power supply to maintain or change its output voltage using a voltage selection unit (fig 8, 307) that sequentially changes the voltage until the ideal voltage is reached. By monitoring the voltage output by the power supplying apparatus the device ensures that the power is output at a level required by an electronic appliance such as a laptop computer.

Abstract: 610,220. Gas turbine plant. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., and ALCOCK, J. F. April 1, 1946, No. 10086. [Class 110 (iii)] [Also in Group XIII] In a gas turbine plant, working on an open circuit, the compressed air is heated in a heatexchanger, expanded in the turbine, then burned with fuel to provide heat in the exchanger and finally exhausted to atmosphere or supplied to some hot-gas user. In the plant shown, the heat - exchanger is a rotating regenerator drum 6 and the central space is divided into two regions 7, 8 by a partition 9. Air delivered by the compressor 4 is heated in passing through the lower part of the drum to the region 7, is expanded in the turbine 11 and fuel is burnt with it in the region 8. The products of combustion give up their heat in passing to the outlet 3 through the upper part of the drum. Liquid fuel may be supplied through a burner 13 or solid fuel may be burned on a grate 14. The chambers 5 and 7 may be heated up for starting by fuel supplied to burners 18, 19. Air bled by a pipe 15 is led to the sealing spaces between the drum and the enclosing casing and serves to scavenge the cells of the drum. The plant may be regulated by means of a valve 17 which passes unheated air direct to the turbine.

Title: Improvements relating to indicating devices
Inventor: RADFORD CHARLES YORK
IPC: G07F17/24
Filed: 1963-03-14
Abstract: 1,058,195. Parking time indicators. VENNER Ltd. Feb. 28,1964 [March 14, 1963], No. 10216/63. Heading G4T. A parking or hiring time indicator includes a counter initially set at a predetermined value and a drive connectable through variable ratio gearing to the counter to drive the counter back towards zero at a selected rate, the rate being indicated externally of the device. As shown, a spring drive 6 rotates a gear train 1 under the control of an escapement 2. A gearwheel 23 of the clock train 1 drives a gear-wheel 24 in a gear train 13, 14, 15, 16 and 17, which, although shown in two-dimensional form, is actually arranged around the spindle of a setting knob 28b so that an idler gear 26, mounted eccentrically, can be set to complete the drive between a selected one of the gears 13 ... 17 and a gear 27 which drives through a worm-gear arrangement 11 the counter 12. A flag indicator is operated when the counter reaches zero. For use as a parking meter, the device is purchased with a predetermined amount registered on the counter and, when desiring to park, the driver of the vehicle on which the meter is carried sets the knob to a reading corresponding to the particular tariff in the parking zone, this set rate being indicated on a disc 28 which is visible from outside the vehicle, so that it can be checked by parking attendants &c. The balance wheel 8 of the clockwork is also visible to check that the device is working. A flag (34, Fig. 3, not shown) is spring-biased so that a follower (30) on its arm co-operates with the cam edge of the disc (28), and when the setting knob is set to the off position, the follower drops into a low (29) in the cam so that the flag (34) moves in front of the aperture (A) through which the balance wheel can be viewed. A pawl (36) is simultaneously moved to a position to arrest the balance wheel.

Title: Improvements relating to track circuit signalling systems for railways and the like
IPC: B61L23/16
Filed: 1944-05-26
Abstract: 576,901. Railway signalling systems. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and COLEY, J. P. May 26, 1944, No. 10217. [Class 105] In a railway signalling system in which interruption coded current is applied to the track sections with a return code transmitted during the " off intervals a special section such as a tunnel has a higher voltage than normal applied on approach of a train by the dropping of a relay which normally is energized in dependence on return code being received m an approach section. The release of a signal lever may be made dependent on such higher voltage being applied. In the automatic signalling system shown the special section BT and an approach section AT are normally supplied with coded current of normal voltage. Thus for the approach section AT a coding contact ATC in its upper position applies battery A1 to the rails at the exit end whereby a code-following relay ACFR at the entrance end is operated, while when the coding contact ATC is in its lower position during the "off" periods, a relay AIRCR, is operated by returncode pulses from.a battery A2 by reason of the closure of a front contact 1 of a relay ARCTR energized by a pulse from transformer ATM each time the code-following relay ACFR drops. It will be seen that relay ARCR is operated only if return code is received and that consequently entry of a train into approach section AT will cause this relay ARCR to remain dropped so to de-energize-its associated slow relays FSR, BSR. The special section BT has a similar code and return-code arrangement normally operated by coding contact BTC and battery B1 at the exit end but the circuits to the code-following relay BCFR and returncode battery B3 at the entrance end include front contacts 2, 1 of the slow relay BSR associated with the approach section AT. With approach section AT occupied these contacts 2, 1 will therefore be open so.that no return code can be given in the special section BT and relay BRCR will therefore drop and in turn drop its own associated slow relay BSR, a back contact 3 of this last relay then applying a higher voltage battery B2 to the rails of special section BT. The code-following relay BCFR will then be energized over a resistance BR (bridging the open contact 2) to compensate for the increased voltage and will therefore energize the signal relay SBHR to clear the signal for the special section BT. In a non-automatic system the release of a signal lever would be made to depend on the dropping of the slow relay BSR at the exit end of the special section by which relay the increased track voltage is applied.

Abstract: 251,274. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts Ges.). April 22, 1925, [Convention date]. Condensers have a dielectric of a natural or artificial resin which is applied in a liquid condition between the conducting layers and which, after solidifying or hardening under pressure, serves as a binding agent for the conducting layers and for the assembling of the condenser. In some cases fine wire gauze or perforated sheet metal is used for the electrodes, and the resins can be applied either in solution or in a melted state. The drying may be effected in a vacuum for quickly removing the solvent, and in the case of high voltage condensers the layers are spaced apart in a chamber and liquid dielectric squirted between them. Specification 105,333 is referred to.

IPC: H04N5/919
Filed: 1954-04-09
Abstract: 758,865. Electric and magnetic recording and reproducing apparatus. BRITISH BROADCASTING CORPORATION. April 12, 1955 [April 9, 1954], No. 10565/54. Class 40(2) [Also in Group XL(b)] In apparatus for delaying television signals (see Group XL(b) ) in which the signals are recorded magnetically or electrically at a first point on a rotating drum or disc and picked up at a second point suitably displaced from the first to obtain the desired delay, variations in the amplitude of the reproduced signals due to changes in the separation of the recording and reproduction heads and the periphery of the drum or disc caused by unavoidable eccentricity are compensated by detecting the changes in separation and controlling the pick-up head spacing so as to reduce the signal variations. In one arrangement a constant amplitude signal is recorded on a separate track (or, by use of a distinguishable frequency, on a signal track) and the amplitude of this signal as picked up is detected to derive a control potential representative of the changes in ' separation. In another arrangement. where the recording medium is metallic, or in the form of a coating on a metallic backing, the detecting device comprises a small insulated metal plate facing the medium and providing an indication of the variation in spacing by the variation in capacitance between the plate and medium. The capacitance variation is employed to produce a varying control potential. Reference is also made to the use of a photo-cell with a beam of light projected through the gap between the recording head and medium. To enable the pick-up head spacing to be varied in response to the control potential, the head 26, Fig. 3, may be carried by a piezo-electric device comprising two thin rods 43, 44 of barium titanate cemented face to face. The outer faces of the assembly are sputtered with a conductive coating and electric connections to the control potential are made via a fixed support 46 and a light phosphor bronze spring 47. In an alternative arrangement (not described in detail) pneumatic means are employed comprising a piston and cylinder responsive to air pressure varied by the electric control signal. Specification 722,962 [Group XL(b)] is referred to.

Abstract: 1,094,551. Screw cutting lathes. FAIREY ENGINEERING Ltd. March 5, 1965 [March 12, 1964], No. 10565/64. Headings B3B and B3T. A device, for use with a screw cutting lathe, for forming relieved areas on the thread flanks of an internally threaded workpiece comprises a cylindrical sleeve 15 which forms a carrier for a reciprocable plunger 16 from which extends a transversely mounted cutting tool 18. The sleeve is mountable on the lathe carriage 13 by a block 22. Within the sleeve is positioned a rotatable face cam 25 against which the plunger 16 bears under the pressure of a spring 27. The rotation of the cam imparts a cyclic reciprocatory motion to the plunger and the tool 18, the latter extending through a slot 17 in the sleeve 15, so as to contact the flanks of the thread of the workpiece 20 held in the chuck 12. The speed of rotation of the cam 25 is the same as that of the chuck, the cam being driven by a shaft 32 connected to the spindle 35 of the lathe. In operation the rotary and cyclically reciprocatory motion causes the cutting edge of the tool 18 to be moved into cutting engagement with a thread flank and to be retracted therefrom after a predetermined travel of the tool along the circumferential length of the thread caused by the traverse of the tool carriage of the lathe. In an alternative arrangement two cutting tools may be incorporated for simultaneous operation.
