Abstract: 461,368. Switchgear structures. ELLISON, Ltd., G., and STRATTON, H. T. Nov. 6, 1935, No. 30665. [Class 38 (v)] Electric switchgear comprises the combination of fixed main and earthing contacts contained in a case, a slidable carriage carrying complementary contacts and movable between the fixed main and earthing contacts, means actuated by the carriage for preventing opening of the lid of the case except when the complementary contacts are earthed, and a hand lever for actuating the carriage. The fixed main contacts c are housed in an oil-containing casing a having a hinged or removable lid b, and connected to bus bars. The main movable contacts are carried on a carriage g, which is horizontally slidable on guides h to separate contacts j from contacts c, and in the other extreme position to bring contacts k into engagement with earthing contacts l. The contacts j are connected by the flexible leads n and pivotally-connected links m to the terminal posts o having sockets p to receive testing plugs. A handle t on a shaft r is adapted to operate the carriage through the lever system s, z, q, and a cam w on the shaft r normally co-operates with a bell-crank y to limit the movement of the carriage to separation of c, j and their arcing-contacts 9, 10. In this position of the parts a further cam 6 has moved clear of the lever y, so permitting the latter to be moved to an inoperative position by a normally-padlocked push piece x, so allowing the handle t to be further rotated for moving the carriage to the earthing position. A flange 7 is apertured at 8 to allow the handle t to be padlocked in any of its three positions. To lock the lid b against removal in any but the earthing position of the carriage, a member 2 on the latter engages in a depending part 3' of the lid. Accidental return of the carriage when the lid is off is prevented by a spring plunger 4, 5 in a removable safety cover f for the contacts c, which plunger only allows movement of the carriage when the lid is replaced.

Abstract: 1,249,556. Phase comparators, automatic phase control. INTERNATIONAL STANDARD ELECTRIC CORP. 19 June, 1969 [25 June, 1968], No. 31042/69. Heading H3A. A phase comparator for synchronizing pulse code modulator receivers comprises means for producing a pulse signal of one polarity having a width variation dependent on the phase difference, means for producing another pulse signal of opposite polarity having a width variation dependent on phase difference opposite the first width variation, and means responsive to the two signals to produce an output signal proportional to the phase differenoe. In one embodiment, Fig. 2, shaped data signals and clock signals, are applied to the set and reset inputs of a bistable 16, one output from which is amplified at 17 to constitute the first variable width pulse signal. The other output is compared in NAND 16 with the output from a monostable 18 triggered by the data signals and the resulting output is amplified at 20 to constitute the other variable width pulse signal. The two signals are then added and integrated at 14 to provide a control signal for adjusting the phase of the clock oscillator (not shown). A second embodiment, Fig. 2 (not shown) includes means for inhibiting the production of false control signals during fades. Also, the control signal is derived from the integrator via a high impedance FET circuit. Instead of a monostable circuit a delay (52) is used to derive one of the two pulse width variable signals.
