Abstract: 794,876. Counting-apparatus. VEEDERROOT, Inc. Aug. 24, 1956 [Sept. 8, 1955], No. 25914/56. Class 106 (1). [Also in Group XXXVII] A mechanism to close,an electrical circuit when a predetermined count is reached on a mechanical counter comprises a spring switch member 31, Fig. 4, secured to each number wheel and having wiper contacts 37, 38 adapted to engage contacts on a fixed stator plate 40, Fig. 3, juxtaposed to each number wheel. Contact 37 engages permanently with an annular contact 46 of the stator plate and contact 38 engages sequentially with contacts 50 to 59 of the stator plate corresponding to readings 0 to 9 of the associated numeral wheel. To operate the device so as to close the circuit between external leads 81, 82 at some predetermined count, the appropriate contact 50-59 of each denominational stator plate is connected to the annular contact of the stator plate of next lower denomination so that a series circuit is closed through the switches only when the required count is reached.

Abstract: 841,541. Waveguide switches. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. May 28, 1958 [Aug. 16, 1957], No. 25987/57. Class 40(8). A waveguide switch or attenuator comprises a conductive partition member containing at least one hole adapted to receive a gasfilled discharge tube and at least one resonant slot in each face, said slot being aligned with said hole and having smaller dimensions than the effective discharge path in said tube. In the arrangement shown the switch or attenuator consists of a slot 1 of a light alloy or of light synthetic insulating material with a metallized surface having two holes 2 and 3 each of a diameter a little less than the thickness of the slot. Resonant slots, each of a width slightly less than the diameter of a hole, are positioned one on each side of each hole, two slots 5 and 6 being shown. A gas discharge tube having a length at least equal to the length of a slot is fitted in each hole. Rectangular waveguides 7 and 8 abut the opposite faces of the slot 1 which may be provided with recesses to receive ends of the waveguides which may be flanged. The gas discharge tubes may be ionized by the incident h.f. wave energy when it exceeds a certain predetermined power (as in a T.R. switch), or ionization may be effected by applying pulses to electrodes provided in the tubes (as in a pulsed attenuator). The slot 1 may be replaced by a diaphragm with thin walled slotted metal tubes let into it to accommodate the discharge tubes. The form of the slot 1 shown may be duplicated to provide a switch or attenuator for operation in conjunction with two waveguides which are side by side-Fig. 2 (not shown) such an arrangement is also suitable for use between and in conjunction with two short-slot 3 db. couplers-Fig. 3 (not shown).

Abstract: 1,219,468. Phase displacement. FEEDBACK Ltd. 30 May, 1969 [31 May, 1968], No. 26223/68. Heading H2F.  In a phase displacement device, an A.C. supply having at least two phases is connected to a voltage divider VR1, preferably a potentiometer, whose output 11 is connected to a low gain amplifier 10 having a positive feedback path which controls the input impedance of the device to maintain the output amplitude constant as the potentiometer VR1 is adjusted to displace the output phase. The two-phase supply connected to VR1 is in phase quadrature.

[Also in Group XL (a)] A microwave generator comprises a waveguide, a pair of electrodes passing through holes in opposite sides thereof to provide a spark gap which is substantially central within the guide section and whose length lies in, or substantially in, the direction of the E vector, means for applying a high potential between said electrodes and means for increasing and decreasing the length of said spark gap at a predetermined frequency. In the arrangement shown, a voltage of the order of 5 kv. is applied at terminals 5 to two tungsten electrodes 2 and 3 projecting through holes in the opposite broad faces of a rectangular waveguide 1 to form a spark gap the length of which lies in the direction of the E vector. Electrode 2 is vibrated by a vibrator 4 which may be a buzzer movement for a frequency of 50 c/s. or a loud-speaker movement for higher frequencies of the order of 500 c/s., so that twice during each cycle of vibration the length of the gap is at the value necessary to produce microwaves of the required frequency. All frequencies above the cut-off frequency of the waveguide are propagated in the guide, and known filtering means may be provided in the guide to select a particular frequency or band of frequencies. The electrodes 2 and 3 may touch once per cycle of vibration. The spark gap may be in vacuo or in air or other gas at any desired pressure or in a liquid such as paraffin.

Abstract: 533,455. Field control of D.C. motors. AKT.- GES. BROWN, BOVERI, & CIE. Sept. 29, 1939. No. 26896. Convention date, Oct. 17, 1938. [Class 38 (iii)] Varying E.M.F.- A motor 7 driving a vehicle and fed from generator 6 driven by a diesel engine 19 has a field-winding 10 separately-excited from a source 8 and controlled automatically in accordance with the speed or armature voltage of the motor, so that with increasing voltage or speed the excitation is reduced. The control may be effected by resistance regulator in the field or by supplying the field through a circuit including an opposing voltage proportional to the armature voltage. Such a voltage may be tapped from a resistance 9, or provided by an exciter driven by the motor. The generator characteristic is preferably selected which conforms to the most economical engine characteristic over a speed range. Braking is effected with the motor returning current to the generator, and in addition a resistance may be connected across the motor when the motor voltage falls below that of the generator.
