IPC: B61L25/04
Abstract: 1,053,026. Truck identification. GENERAL ELECTRIC CO. March 5, 1964 [March 19, 1963], No. 9385/64. Heading B7N. [Also in Divisions G4 and H4] A railway truck identification system comprises, Fig. 1, a transmitter 11 for generating a plurality of signals at different frequencies, a receiving unit 19 and an identification device 21 for attaching to the truck, comprising a plurality of elements 22/29 each resonant at a different one of said frequencies for coupling the transmitter to the receiving unit, the receiver 19 being adapted to receive those signals at which the elements are resonant to provide an indication representing the identification device and the corresponding truck. The transmitter comprises a sweep oscillator 11 generating a continuous signal sweeping from 600 kc./s. to 510 kc./s., the signal being at frequencies of 590 kc./s., 580 kc./s., 570 kc./s., 560 kc./s., 550 kc./s., 540 kc./s., 530 kc./s. and 520 kc./s. for periods of 2 m.sec. each. The generated signal is fed via an amplifier to a horizontal loop aerial 15 positioned between the tracks, and to a clock 41, which produces pulses 1 to 8 in synchronism with the sweeping of the signal through frequencies 590 to 520 kc./s. The identification device 21 comprises eight lead zirconatetitanate or barium titanate crystals 22/29 resonant at the eight frequencies 520/590 kc./s. respectively and connectible via switches 32/39 to an aerial 31. Crystals 22 and 29, respectively resonant at 520 and 590 kc./s. are always connected to the aerial 31 and serve to provide checking signals, whilst crystals 23/28 are connected to the aerial in a combination defining a two digit binary code identification number of the truck. Crystals 28, 27 and 26 represent the first digit, having values respectively of 1, 2 and 4. Thus to represent a first digit of six. crystals 28 and 27 would be connected to the aerial. Crystals 25, 24 and 23 similarly represent the second digit with respective values of 1, 2 and 4. Signals at frequencies corresponding to the crystals connected to aerial 31 are received by horizontal loop aerial 17, so positioned as not to receive radiation from aerial 15 directly, in the same time sequence as they are generated by oscillator 11. Each signal produces a pulse which is fed to logic means 43 where the received frequencies are identified by determining which clock pulses coincides with the received signal. The identification number of the track is then determined and passed to separate punch-out display means. If the check signals at 590 and 520 kc./s. are not received then the received signals are treated as suspect and ignored.

Abstract: 1,053,222. Centrifugal separators. AMETEK Inc. Aug. 9, 1963, No. 31575/63. Heading B2P. A centrifuge for separating solids from slurries having relatively low solids content comprises a drum 10 rotating about a horizontal axis and a separator-conveyer assembly 42 mounted within the drum 10 for rotation at a different speed about the same horizontal axis and forming with the drum a solids chamber and a liquid pond in coaxial relation to each other, the slurry being continuously fed by means of a pipe 59 along the axis of the drum at one end thereof and the separated liquid being removed by means of a skimmer tube extending into a liquid collecting chamber 24 at the other end of the drum and adapted to maintain a constant depth of liquid in the chamber. The slurry is accelerated to the speed of rotation of the liquid pond prior to reaching the latter by means of a conicalthroated member 50 in corporating vanes 56. The drum 10 is driven directly by means of a pulley 15, and the assembly 42, comprising a tubular element 43 to which are fixed longitudinally-spirally extending vanes 47 surrounded by a spiral strip 52, is driven at a a lower speed than the drum from an end shaft 25 thereof through a two-stage epicyclic gear reducing unit 35 and a splined connection 41. The spiral strip 52 extends around the conical member 50 and serves to remove accumulated solids from the inner surfaces of the drum and of a truncated conical hollow insert 16 and convey them to a chamber 17 and thence through ports 18 to a chamber 19 within a housing 20 surrounding the drum 10. The liquid component of the slurry discharges through ports 22 into the chamber 24 from which it is removed by the skimmer tube 70 which is connected to an axially displaceable non-rotatable threaded shaft actuated by a handwheel to adjust the position of the nozzle 71 of the tube 10 for maintaining the liquid pond at the desired radial dimmension. The conical member 50 is secured to the vanes 47 and is supported in a bearing. The vanes 56 are mounted on a rod 54 and are resiliently urged into frictional contact with the inner surface of the member 50 by means of a spring 57. The sun gear 61 of the gear unit 35 is normally held stationary by an overload linkage comprising an arm 63 fixed to the sun gear shaft 62 and abutting a spring-loaded bell crank 64, 65, Fig. 2. Should the centrifuge become overloaded, the arm 63 trips the bell crank to its dotted position thereby permitting rotation of the sun gear 61, and interruping the rotation of the separate conveyer 42 until the overload is reduced.

Abstract: 1,053,551. Measuring heat quantities. C.U.R.A. PATENTS Ltd. July 4, 1963 [April 5, 1962], No.13226/62. Heading G1D. A heat meter for a liquid heating system, which comprises a pipe 1 forming part of the return main of the heating system for a region to be heated, where the main leaves the region, a conduit 2 communicating with the pipe 1 at points spaced along the length of the pipe 1, the conduit comprising two tubular members 5, 6 one extending within the other, the outer of which, 6, communicates at one end with the pipe 1 and is closed at its other end, and the inner of which communicates at the same one end with the pipe 1 and at the other end with the interior of the member 6, a substantially constant minor proportion of the liquid flowing in the pipe 1 entering the conduit by way of the member 5 and leaving by way of the annular space between the members 5, 6, a heater 8 supplying heat to liquid within the member 5, a switch 19 for causing the heater to be switched on and off, control means responsive to the difference between the temperature of the liquid at a point within the conduit downstream from where the liquid is heated and the temperature of the liquid entering the region to be heated, the control means switching on the heater only when the first mentioned temperature is less than the latter, and an electric timer 20 for recording the time during which the heater is switched on, at least the portion of the conduit extending between the positions of the heater and the point at which the first mentioned temperature is taken being thermally insulated and the control means comprising two temperature responsive devices 9, 15 each consisting of a rigid vessel 10, 16 containing a volatile liquid and a bellows 12, 17 communicating with the inside of the vessel. In use, the liquid enters the region to be heated by way of a pipe 14 and the liquid temperature is sensed by the vessel 16 which acts on the bellows 17. Liquid enters the conduit 2 from the return pipe 1 and its temperature is sensed by the vessel 10 acting on the bellows 12. If the two temperatures are not the same, i.e. if that in the conduit 2 is lower then the switch 19 is closed to switch on the heater 8, the time for which it is on being registered on the timer 20. The temperature in the conduit 2 is thus maintained the same as that in the pipe 14 and the timer 20 gives an indication of the quantity of heat consumed. A constriction 22 in the pipe 1 ensures flow of liquid through the conduit 2, and the conduit also contains a constriction 23 to keep the flow therein turbulent. The heater 8 is embedded in a block of material which is a good conductor of heat to give more uniform heating of the liquid.

Abstract: 1,238,918. Colour television. FERNSEH G.m.b.H. 19 Aug., 1968 [19 Aug., 1967], No. 39486/68. Heading H4F. In a colour television camera in which a separate pick-up tube 4 is employed to derive the luminance signal Y, a switching signal from a trigger circuit 15, for example a Schmitt trigger, is applied to suppress the colour information when the luminance input Y to circuit 15 exceeds a predetermined level. The colour component signals are derived in a known way, using pick-up tubes 6 and 7 and in matrix 10 by combination with the luminance signal. The amplifiers 11-14 provide gradation correction as well as amplification. The switching signal produced by the trigger 15, for example as a result of over-modulation of the luminance signal, actuates an element which causes the signal paths R<SP>1</SP>, G<SP>1</SP>, B<SP>1</SP> to be interrupted. In the embodiment shown, one stage of each of amplifiers 11-14 is blocked by the switching signal to achieve this effect.

Abstract: 1289614 Control of A.C. motors T A O GROSS 6 Feb 1970 [17 Feb 1969] 5728/70 Heading H2J A universal motor, having stator and rotor windings 10, 11 whose relationship is reversed to provide dynamic braking when the motor is disconnected from its supply, is provided with a control circuit comprising members 15-19 to ensure generation of the braking E.M.F. when the disconnection occurs. A changeover switch 14 is moved to its ON position to connect windings 10, 11 in series across an A.C. supply 12, 13 and also to charge a capacitor 17 from this supply through members 15, 16, 18. When switch 14 is moved to its OFF position, windings 10, 11 are mutually reversed and connected in series with members 17, 18 so that discharge of capacitor 17 establishes in the motor magnetic circuit a flux level sufficient to cause generation. After discharge of the capacitor 17 a diode 19 becomes forwardbiased to allow the generated current to by-pass the capacitor. The switch 14 is preferably slow acting to permit decay of the motor flux to about the residual level before the capacitor current begins to flow. The load resistor 18 may be a discrete element or may be embodied in the supply lead or in the motor, for example as part of the compensating winding(s) of the motor. A discussion is given of the factors affecting the variation of the current through resistor 18 during braking, Fig. 2 (not shown), and of the effect of the resistor 18 on brush wear.
