Title: Loop filter for phase locked loop
Inventor: VRY MICHAEL GEOFFREY
IPC: H03H17/04
Filed: 1981-11-04
Abstract: A loop filter for a phase locked loop includes an A/D converter having an input (20) to which the analogue error signal is applied which is connected to a first input of an amplitude comparator 22. A reference source (23) which produces a uniformly distributed random amplitude reference signal is connected to the second input of the comparator (22) which as a consequence produces a stocastic sequence of pulses in which the number of logic '1' pulses depends on the amplitude of the error signal. These pulses are fed to an accumulator (28) which accumulates the pulses over a given period defined by pulses generated in the timing generator (37) and applied to input (43) of the accumulator (28). The accumulated total is stored in a latch (49) and applied to the input (30) of a digital filter 31. The filter enables the use of a digital filter (31) while simplifying the analogue to digital converter to a comparator (22), an accumulator (28) and a reference source (23) all of which can be conveniently integrated. <IMAGE>

Title: Improvements in or relating to trailer and semi trailer vehicles
IPC: B62D53/06
Filed: 1981-11-18
Abstract: The invention relates to trailer and semi trailer vehicles, particularly those to carry substantial loads upwards of 100 tons, and is directed to providing a trailer vehicle which is manoeuverable both in close quarters and around tortuous corners on highways, and which spreads the weight of a load advantageously over the axles supporting the trailer and tractor vehicle. In a trailer vehicle assembly comprising a main trailer frame 10 supported at the rear portion thereof by means of a number of wheeled rear axles 11, means are provided to steer the wheels of said rear axles either in a first mode in which the wheels of all the ax/es 11 are steered by the same angle at any time, or in a second mode in which the wheels of each successive more rearward axle 11 are steered by a greater angle than the wheels of the adjacent more forward axle.   The main trailer frame is supported at a rear portion thereof by the axles 11 and is arranged to be supported at a front portion thereof by a tractor vehicle through the intermediary of a balancer frame 12 coupled and supported at the front by a fifth wheel coupling with a tractor vehicle 9 and to be supported at the rear by a number of steerable axles 14, the front portion of the main frame being supported on the balancer frame to pivot about a horizontal axis 13 running transverse to the length of the vehicle. <IMAGE>
Patent GB-817557-A (GB)
Abstract: 817,557. Cold-cathode tubes. MULLARD Ltd. Oct. 22, 1956, No. 32099/56. Class 39(1). A cold-cathode trigger tube comprises a rodshaped main anode, an unapertured main cathode, a separate auxiliary electrode, a separate trigger electrode and additional means for priming the gap between the trigger electrode and the auxiliary electrode, and no other electrodes, the distance between the auxiliary electrode and the trigger electrode being less than the distance between the trigger electrode and any other electrode, so that, in operation and with the tube in a non-conductive condition, the breakdown voltage between the trigger electrode and the auxiliary electrode is less than the breakdown voltage between the trigger electrode and any other electrode. In one form, Fig. 2, the tube comprises a priming anode P and a main anode A in the form of straight wires, a plate main cathode K, a wire auxiliary cathode AK bent to a flat zig-zag form, and a bent wire trigger electrode T. In an alternative form, Fig. 3, the priming anode P, main anode A and trigger electrode T are straight wires, and the main cathode K and auxiliary cathode AK are small curved metal sheets. The tube is connected in a circuit, Fig. 1, in which the main anode A and priming anode P are connected respectively through resistors R1 and R3 to the positive terminal 11 of a d.c. supply, and the main cathode K and auxiliary cathode AK are connected directly and through a resistor R2 respectively to the negative terminal 12. Application of a positive-going pulse to the trigger electrode T breaks down the trigger electrode-auxiliary cathode gap, followed by breakdown between the anode A and cathode K. While the tube is conducting a discharge current flows between the main anode A and the auxiliary cathode AK, but is limited to a small valve by the resister R2, and negligible sputtering of the auxiliary cathode AK occurs, thus reducing to negligible proportions the hysteresis effect, i.e. the effect in trigger tubes whereby the trigger breakdown voltage has a lower than normal and varying value for a short period following a discharge and which is believed to be due to the re-forming on the cathode of a thin film of contamination which is removed by sputtering during the discharge. The priming anode P may be replaced by or aided by radioactive material located on a surface of one of the electrodes or on the internal surface of the tube envelope.

Abstract: An apparatus for testing a battery 1 comprises a source of predetermined voltage 3 having its positive terminal connected through a capacitor 7 and resistor 5 to a terminal Y and its negative terminal connected via a switch 11 and fuse 40 to terminal X. A battery to be tested 1 is connected across terminals X and Y and upon closure of switch 11 the capacitor 7 is charged up to the predetermined voltage in excess of the open circuit voltage of the battery 1. A timing pulse from a timer 13 passes through an open gate 14 to cause a switch 12 to go short circuit thereby shorting the capacitor 7 through the battery 1. Discharge of current flow through the battery 1 is monitored by a sample and hold unit 4 detecting the voltage across resistor 5. An alarm means 34 can be provided which is responsive to a comparison between the sensed discharge current and a predetermined threshold current level. A further sample and hold unit 16 senses a voltage difference between the discharge voltage across the battery 1 and the open circuit voltage of the battery 1. A divide 19 divides the voltage difference by sensed discharge current to produce a value proportional to internal resistance of the battery 1 which can be displayed on a meter 21. Means are also provided to detect incorrect connection of battery 1 to the battery testing apparatus and means to discharge capacitor 7 when battery 1 is disconnected from the apparatus. <IMAGE>
