Title: Fault location arrangement
IPC: G06F11/16
Filed: 1964-05-22
Abstract: 1,016,568. Electric selective signalling. STANDARD TELEPHONES & CABLES Ltd. May 22, 1964 [May 27, 1963], No. 21218/64. Heading G4H. In a recoding circuit there are two identical logical circuits S1, S2, each effecting the recoding and comparators A1-An for comparing the individual bits of the outputs of the two circuits and means which upon disagreement being detected causes a test circuit to determine which of the two outputs satisfies a parity check so as to indicate which of the logical circuits S1, S2 is faulty. As described the input from source W, in binary scale, passes via gates L1-Lm and L<SP>1</SP>1-L<SP>1</SP>m to the circuits S1, S2. The outputs are in the form of markings on two out of five leads. Corresponding leads in each output are connected to comparators A1-An. A disagreement sets trigger X1 causing input gates L1-Lm and L<SP>1</SP>1 to L<SP>1</SP>m to be blocked. The output gates G1-Gn and G<SP>1</SP>1-G<SP>1</SP>n are also blocked. The outputs from circuits S1, S2 are entered in shift registers R1, R2. Trigger X1, when set, sets trigger X<SP>1</SP>1 to open gates P, P1 to allow clock pulses to pass from generator PG to counter C and to cause the data in stores R1, R2 to circulate. The " 1 " bits are counted by scale-of-two counters Y1, Y2. If both outputs have the correct parity (even) gates Q2 and Q3 respond. Incorrect parities enable gates Q1 and Q4. If both these gates respond a general alarm is given. An incorrect parity on one output only gives an output from gates Q5 to Q6 to set triggers Y3 or Y4. The set outputs of either of these triggers resets trigger X1. The input and output gates relating to the faulty circuit S1 or S2 remain blocked so that it is effectively switched out of use. The register R1 or R2 relating to the non-faulty circuit is read out through gates G1-Gn or G<SP>1</SP>1-G<SP>1</SP>n. In another form the parity is tested by a parallel-type circuit to avoid the use of a recirculating shift register.

Title: Electrical apparatus for measuring the proportions of mixtures and solutions
IPC: G01N22/00
Filed: 1944-11-06
Abstract: 595,720. Inductance and capacitance measurements ; determining physical qualities of materials; magnetic tests and measurements. ACE ELECTRONICS, Ltd., WELCH, L. C., and COOK, R. J. Nov. 6, 1944, No. 21739. [Class 37] An apparatus for determining the nature of mixtures or solutions and for determining the amounts of various substances present in a mixture or solution containing known substances in unknown proportions comprises an electromagnetic oscillatory system arranged to receive a sample to be tested so that the sample is located in predetermined relation to inductance or capacity elements of the oscillatory system and means for indicating the damping effect of the sample on the oscillatory system. A sample of a mixture in a container 3, Fig. 1, absorbs energy from an oscillatory system comprising a single-loop coil 1 and a pair of condenser electrodes 2 connected to the ends of the coil so as to form a very high frequency series tuned circuit energized by a valve 4. This has an effect on the grid current depending on the conductivity or dielectric loss of the sample so that the reading of a microammeter 9 is different for different mixtures. By plotting the readings of the different constituents, a curve can be obtained, so that for any reading the relative amounts of the constituents can be determined. In a modification, Fig. 2, a saw-tooth wave, produced by valves 19, 17 and condenser 18 and varied cyclically by the mains voltage 20, is applied to the oscillatory system 1, 2 so as to produce a response which rises to a maximum when the frequency of the oscillations is equal to the resonant frequency of the oscillatory system. This response, in the form of a series of surges, is synchronized with the peak response of the oscillatory system and applied to the Y-plates of a cathode-ray oscillograph 22. A voltage proportional to the resonant frequency of the oscillatory system is applied to the X-plates, so that the beam traces on the screen a line having a sharply defined position and a height depending upon the conductivity and dielectric loss of the sample. The position of the line along the X-axis depends mainly upon the magnetic permeability and specific inductive capacity of the sample under test. In another modification, Fig. 5 (not shown), the oscillatory system consists of an inductance coil connected at its ends to two cylinders. In a further modification, Fig. 7 (not shown), the inductance coil and the condenser electrodes are immersed into a liquid which is to be tested.

Abstract: 1,178,944. Change-speed control. BORG-WARNER CORP. 8 May, 1968 [5 June, 1967], No. 21862/68. Heading F2D. A gear-change mechanism incorporates interlocking mechanism between the shift rods which also engages with end stops on the rods to prevent their movement beyond the gear engaged position. As shown a pair of shift rods 22, 23 operated by a ball mounted gear change lever have grooves 30, 31, 32 at one end engageable by a ball detent 36 and at the other end have a groove 50 between shoulders 52, 53. The interlocking member consists of a transversely movable pin 71 with rounded ends which, on the rod 23 being moved to the gear engaging position shown, is forced into engagement with the groove 50 of rod 22 to lock it in the neutral setting and at the same time engages the end stop shoulder 53 to prevent any further movement of rod 23. As applied to an arrangement with three shift rods, Figs. 5 and 6 (not shown), a pin 71 is mounted on each side of the central rod (22A) with a plain transverse interconnecting pin (81) mounted in the central rod.

Abstract: 409,711. Switching and control systems for illumination circuits. GENERAL ELECTRIC CO., Ltd., DAVIS, B., ELLIS, G., Magnet House, Kingsway, London, and COATES, H. J., c/o General Electric Co., Witton, Birmingham. Aug. 4, 1932, No. 21880. [Class 38 (iv).] Groups of lamps 1, 2, 3 supplied from lines 4, 5 are sequentially dimmed by associating each in turn through a switch drum 63 with a generator 157 arranged to buck the supply voltage, the generator excitation being variable by an arm 120 rotating with the switch drum 63 so that each lamp is connected to the mains through the fully excited generator so as to be dim. The generator excitation is then reduced so as to bring the group of lamps up to full brilliance, when the generator is given a reversed excitation, and short-circuited before the lamps are disconnected from it and connected direct to the supply. Later in the cycle the generator is re-connected to the bright group of lamps when it is generating no voltage and its voltage is increased so as to dim the lamps which are disconnected when they are at zero brilliance. The cycle is repeated with each revolution of the drum 63, the arm 120 rotating three times as fast as the drum. Each group of lamps is provided with a switch 7, a main contactor switch 12, 13, 14 and a switch 15, 16, 17 which, in its upper position, provides continuous illumination and, in its lower position, connects the group to the contact drum 63 and booster generator 157. The coil 34 of each contactor is closed by a switch 45 and a holding circuit completed through the drum switch so arranged that the lamp circuit cannot be opened except when its lamps have been dimmed. For dimming, the contactor circuits are not completed until the contactor 172 of the generator circuit is closed, the closure of this contactor being controlled by depression of a " start " button 143 or of a " stop " button 147 and by an isolating switch 166 which starts the generator motor 160 by closing its contactor 197, thereafter affecting closure of the contactor 172, through auxiliary contacts 198A on the contactor 197. The energization of the contactor 197 is controlled by a contactor 199, 200 responsive to the armature voltage of the drum motor 118 which is energized on closure of the " start " button 143 so that the contactor 197 cannot close until the motor 118 is up to speed. The drum switch 63 and the controller 120 of the booster shunt field 156 are arranged so that when the booster voltage is zero a small reverse field current is passed to kill the residual field prior to and after short-circuiting the booster during the cycle of rotation of the arm 120.

The notches may terminate in holes b constituting lifting eyes and they may be flame cut. The polygon may also be flame cut to a circle to fit outside the magnet ring and may be electrically welded thereto. Alternatively, the ribs may be placed against the ends of the magnet ring, and where the ring is axially divided, an additional rib may be placed between the two portions of the ring as shown in Fig. 6.
