Title: Improvements in sealing glands for electric cables
Inventor: MOORE FRANCIS JOHN
IPC: H01R13/59
Filed: 1961-08-08
Abstract: 950,112. Mechanical couplings for cable sheathing. BRITISH INSULATED CALLENDER'S CABLES Ltd. Aug. 7, 1962 [Aug. 8, 1961], No. 28624/61. Heading H2E. [Also in Division F2] A bung 2 used for sealing plastics-sheathed cables into the bores of plastic pipes, is made up of tacky plastic tape 4 lapped around the cable 3, and has end compression plates 5 with flexible rims 8 to confine the plastic material so that when the bung is compressed axially by means of tie-bolts 10, the material expands radially and adheres to the bore and to the cable, the rims being radially expanded to press against the wall of the bore. The compression plates comprise polyethylene discs 5 and reinforcing metal rings 9, and tie-bolts 10 are of nylon. In an alternative construction of compression plate (Fig. 2, not shown) the flexible outer rim is provided by two split rings of polyethylene squeezed between the chamfered outer edges of an inner polyethylene disc and of a rigid metal or polyvinyl chloride ring. A cable joint housing sealed at the ends with the above bungs may be pressurized by a valve (Fig. 3, not shown). Any of the above plastic discs may be provided with concentric grooves so that holes for different sizes of cables can be cut therein.

Title: Multistable storage with a series-connection of tunnel diodes with different peak currents
IPC: H03K17/28
Filed: 1964-07-10
Abstract: 1,040,490. Pulse circuits. STANDARD TELEPHONES & CABLES Ltd. July 10, 1964 [July 11, 1963], No. 28652/64. Headings H3P and H3T. [Also in Division G4] A multi-stable storage circuit comprises a number of series connected tunnel diodes which are successively switched to store information and successively restored on reading out, the voltage pulses occurring on switching being fed back to the writing and reading circuits. In the Figure the tunnel diode chain TDK is controlled through a diode gating circuit which selectively passes positive or negative-going signals generated by a cross-coupled transistor circuit selectively operating either as a bi-stable or a monostable circuit. With the switch KU closed and Tr 1  conducting D1 is forward biased from the + 2 v. supply. When Tr 2  is conducting its base current is supplied by RZ. Accordingly the circuit of Tr 1  and Tr 2  is bi-stable. When KV is open, the emitter of Tr 1  is connected to earth through diode D2 and D1 does not conduct, so that the circuit is now monostable. Also, with switch KV closed the output of the diode gate D3-D6 will be forced to follow the input voltage to earth but not to the negative rail voltage since only the lower branch D5, D6 is effective but with the switch open only branch D3, D4 is effective and the output will follow the input to the negative rail voltage but not to earth. The multi-stable storage circuit comprises a number of tunnel diodes TDK of successively increasing peak current value connected in series with an inductor L. To write into the store KU is closed so that Tr1 and Tr2 operate as a bi-stable circuit and pulses are are applied to the base of Tr 2 , each pulse cutting off Tr 2 . Tr 1  accordingly conducts, bringing the input of the gate and thus the output towards earth so that current builds up in the inductor tunnel diode series circuit until one of the diodes switches. The resulting pulse across the diodes is fed back through Tr 3  to reset the bi-stable circuit. Thus, successive input pulses switch on additional diode. To read out the store, switch KU is closed. D3 and D4 now connect the diode series to the negative rail so that the current in the tunnel circuit decreases until one diode restores. The resulting voltage pulse fed back through Tr 3  triggers Tr 1 , Tr 2 , now operating as a monostable circuit, causing the negative voltage applied to the tunnel diodes momentarily to be reduced and then restored. Thus successive diodes are restored producing a number of output pulses equal to the number of input pulses stored.

Title: Slip limiting system for a motor vehicle
IPC: F02P11/02
Filed: 1974-06-27
Abstract: 1448423 Anti-wheel-spin systems for vehicles REGIE NATIONALE DES USINES RENAULT 27 June 1974 [24 July 1973] 28655/74 Heading B7H [Also in Divisions G3 and F1] A control system for retarding the ignition of the engine of a motor vehicle when slipping of the driving wheels is detected has provision for applying selectable different delays in the ignition circuit in dependence on the duration of the wheel slip. In the arrangement shown sensors 5, 6 attached to nearside driven and driving wheels produce pulses for counter 25 and a similar offside arrangement supplies pulses to counter 26 such that under normal conditions the counters remain at zero becuse more pulses are produced by the driving wheel sensor. Ignition pulses from contact breaker 11 normally pass from shaper 32, through an undelayed link in register 34 to power stage 38. Additionally these pulses are used by clock 33 to set up a plurality of delay connections in shift register 34 and additionally are time divided to form clock pulses for selector 36. The signal to selector 36 consists of a slip indication and also a signal indicating that the count in a counter has reached a given level and both signals are necessary to cause selector circuit 36 to operate. When wheel slip occurs the respective counter output rises and causes the two NAND gates in circuit 27 to energize selector 36 to change the undelayed connection for a delay connection in multiplexer 31 thus retarding the ignition. Selector 36 also includes a counter for the clock pulses from divider 35 and this is effective to change the connection in multiplexer 37 to provide a greater delay and thus retard the ignition further. A reset signal device is provided which disables selector 36 when the brakes are applied or the accelerator pedal operated.

Abstract: 1,235,472. Transistor amplifiers. TEXAS INSTRUMENTS Ltd. 9 Aug., 1968 [21 June, 1967], No. 28660/67. Heading H3T. A transistor (such as VT1, VT2 or VT3, of a distributed amplifier, Fig. 1) is connected to an input transmission line IBL1, IBL2 or IBL3 by means of an impedance transformer MNI which matches the line characteristic impedance to the resistive component of the transistor input impedance, and which includes the reactive component of the transistor input impedance and a section of transmission line. The transistor outputs are connected to an output line OPL by networks MNO which ensure that the outputs are added in phase. Each input impedance transformer MNI consists of an inductance and a capacitance (Fig. 3, not shown). The input impedance of each transistor at the high frequencies of operation is regarded as being a series inductance (L 1 ) and a shunt resistance (R I ). The input line (and output line) is a strip line having a conductive layer separated by a dielectric layer from a ground plane, the width of the conductive layer which carries the input signal being reduced each time a branch line IBL1 &c. goes off. The output coupling circuits (Fig. 5, not shown) include an inductance, which couples the transistor output capacitance (C o ) and resistance (R o ) to the output line. The input coupling circuits may include a quarter wavelength section strip line connected to the L-C circuit (Fig. 4, not shown) and it is said that they could be Tchebycheff or Butterworth filters.
