Title: Improvements in voltage surge diverters
IPC: H01T1/04
Filed: 1969-09-09
Abstract: 1,274,887. Surge diverters. GENERAL ELECTRIC CO. 9 Sept., 1969 [16 Sept., 1968], No. 44425/69. Heading H2H. A lightning arrester comprises a currentlimiting gap in series with a valve resistor, and has an extra valve resistor which can be shunted out after a time delay following sparkover of the current-limiting gap and before said gap clears and seals off. In the arrangement of Fig. 1, the extra resistor 4, together with a horn gap 8 and grading resistor 10, is connected in series with the main gap 2 and resistor 3. In operation, a surge causes both the gap 2 and the horn gap 8 to sparkover and the arc in gap 8 is then blown out through positions 13 and 14 until it forms an arc 15 between a pair of auxiliary contacts 9, when the latter will shunt out both the gap 8, which is now extinguished, and the extra resistor 4. In other embodiments, the grading resistor 10 may be replaced by a blowout coil, and the extra valve resistance may be split into three series connected resistors. Also, the main arrester may be of the two column flip-flop type. The extra resistor ensures that a system voltage is not reduced too sharply when a surge occurs, and its shunting out prevents too high a discharge voltage building up across the arrester, which is particularly suited for use with a high voltage D.C. system.

Abstract: 1,194,337. Traverse guide control; building motion. ERNEST SGRAGG & SONS Ltd. 27 Sept., 1967 [6 Oct., 1966], No. 44761/66. Headings DID and D1J. A yarn traverse guide 10 in a packaging mechanism has the length of traverse determined by a pair of limit switches 12, 13 which are independantly adjustable along a mount 16 which, in operation of the mechanism, is itself progressively displacable parallel to the adjustment of the limit switches. As shown, the movement of the mount 16 is limited by switches 20, 21, the mount being movable backwards and forwards as by reversible motor 19 or in very short steps in a given direction between the switches. One of the limit switches e.g. 13, can be rendered inoperative and if desired a stationary limit switch 26, can cause reversal of guide 10. The switches can be electric, hydraulic or pneumatic switches. The traverse guide 10 may form part of a ring rail of a ring spinning machine or a traverse guide which moves axially of a package.

Title: Improved magnetic-tape signal reproducing system
IPC: H04N9/89
Filed: 1962-12-03
Abstract: 988,070. Automatic phase control systems. AMPEX CORPORATION. Dec. 3, 1962 [Jan. 2, 1962], No. 45679/62. Drawings to Specification. Heading H3A. In reproducing colour television signals from magnetic tape pulses are derived from the reproduced colour burst of subcarrier frequency, once every alternate wave cycle, e.g. at a positive-going zero amplitude cross-over, and phase compared with a sawtooth wave derived from a reference subcarrier source and of twice the period of this subcarrier, to derive a control voltage electronically adjusting the delay of a delay line through which the reproduced colour signal passes, and thereby correcting any phase error. Control is therefore exercised over a 360 degrees phase difference range. The reference subcarrier may be applied to a cross-over detector producing pulses at every positivegoing zero of the wave cycle, which after a short delay trigger a bi-stable circuit enabling an AND gate to pass every alternate such pulse to a sawtooth generator feeding a phase detector. From the reproduced colour television signals the colour burst is gated to a pulse gate generating pulses at, e.g., positive-going zero crossovers and applied to a second AND gate opened only by the other phase of the bi-stable circuit. The output pulses halved in frequency from the second AND gate then actuate a monostable circuit of period exceeding that of the pulses and this opens a third AND gate to pass the pulses from the colour burst cross-over detector (delayed by a short delay) to the phase detector (via a sampling pulse generator). The above fine control system may be combined with a coarse electronic phase control system in addition to the usual tape speed control. Specification 915,254 is referred to.

Title: Circuit arrangement for the evaluation of received osicillations of predetermined frequency
IPC: H04Q1/448
Filed: 1975-11-04
Abstract: 1523780 Remote control LICENTIA PATENT VERWALTUNGS GmbH 4 Nov 1975 [27 Nov 1974] 45725/75 Heading G4H In a circuit arrangement for evaluating the duration of a first signal containing oscillations of a predetermined frequency, the number of oscillations is ascertained and stored, then in response to a second signal, containing oscillations of another frequency, this number is conveyed to a control circuit by decrementing the stored number. As disclosed, an ultrasonic control signal consists of a duration-significant portion of a first frequency followed by a portion of a second frequency. The two portions, after conversion to electric form, are separated on to respective leads, the pulses of the first portion being gated to a first counter, recognition of a count of 4800 at the high order end of the counter causing the signals from a lower stage of the counter to be gated to the count-up input of a reversible counter. Arrival of the second portion of the control signal blocks the input to the first counter and causes clock pulses to decrement the reversible counter to zero relatively quickly, the clock pulses actually used in this decrementing also going to a control circuit to select the channel of a TV set. Other control functions can be controlled by a count range starting at 3200 (as against 4800 above, but otherwise in a similar way).
