Abstract: 798,833. Time switches. TELEDICTOR, Ltd. April 24, 1956 [Feb. 10, 1955], No. 3950/55. Class 38 (5). [Also in Group XXXVI] An electrically - driven adjustable time switch is incorporated in an adaptor 10, Fig. 1, having plugs 101 and sockets 102 for connection in series between a mains socket and apparatus to be controlled, the switch motor being connected to the plugs and carrying adjustable arms 15, 16 on its shaft. Connection between the plugs 101 and sockets 102 is by resilient switch arms 201, 202, Fig. 2. When the switching on time approaches peg 152 bears against spring-loaded arm 17 formed with an arcuate cam 171 turning peg 181 on a spring- loaded drum 18 anticlockwise until latch 182 passes locking notch 221 on spring-loaded lever 22. Drum 18 carries the switch arms 201, 202 which move towards contacts 11, 12, but arm 201 is restrained by stop-roller 172, on lever 17 until the latter disengages with peg 152, when the circuit through the adaptor is completed. The mechanism is tripped when the " of " time is reached by a pin 162 an arm 16 striking the lever 22, thus freeing latch 182. The arms 15, 16 are mechanically coupled to pre-set pointers 151, 161 moving over a dial 132. Manual operation of the switch is obtained by moving pegs 173, 222 anti-clockwise in arcuate slots 108, 109.

Abstract: 887,545. Laminates and laminating. FORSCHUNGSZENTRUM DER LUFTFAHRTINDUSTRIE. Feb. 5, 1960, No. 4110/60. Class 140. In honeycomb structures useful as stiffening material in building or aircraft components and comprising sheets of fibrous or fabric material adhesively secured together along parallel lines which are staggered in adjacent sheets, the sheets so secured being cut into strips which are expanded into a honeycomb and consolidated with a hardening synthetic resin, the adhesive used is in the form of thermoplastic strips laid between the sheets and actuated by heat and pressure. The sheets and strips may be built up into a pack and subsequently heated, or may have the adhesive strips applied to them in succession, the latter being softened by heat before or after the application of each succeeding sheet. As shown, sheets 1 with interleaved and staggered thermoplastic strips 2 are compressed between plates 3 by mechanism 4, P, and are heated by high-frequency electrodes 5, by infra-red radiation, heating coils, or in a furnace. The strips 2 may extend beyond the sheets and be held in place by clamps such as 7. After cooling, the sheets are cut into strips which are expanded, impregnated with a synthetic resin and rigidified by hardening the resin.

Title: Improvements in or relating to transistor circuits for comparing electrical voltages
Inventor: COWLIN PHILIP
IPC: H03K17/64
Filed: 1958-02-07
Abstract: 916,321. Transistor comparator circuits. BAILEY METERS & CONTROLS Ltd. Feb. 6, 1959 [Feb. 7, 1958], No. 4153/58. Class 40 (6). In a voltage comparator a variable voltage applied to the base of a first transistor is compared with stable reference voltage derived from a Zener diode and applied to the base of a second transistor, the stable voltage being in series with the emitter-base voltage of the second transistor in the emitter base circuit of the first transistor so that variations in output current caused by changes of emitter base voltage of the first transistor due to temperature changes are commensated by variations in the base emitter voltage of the second transistor. In the Figure an alternating current input voltage is applied through terminals X to the base of a first transistor T1 while a reference voltage is applied from a Zener diode Z6 to the base of the second transistor. If the input voltage exceeds the voltage applied to the base of the second transistor sufficient current flows in the first transistor to operate a relay 15. Variations in the operation of the circuit due to variations with temperature of the base emitter circuit of the first transistor are compensated by corresponding variations in the base emitter circuit of the second transistor, the two transistors being mounted in closely-spaced holes in a relatively large metal block. Temperature compensation for the Zener diode Z6 is effected by a temperature-sensitive resistor R5.

Abstract: 548,119. Electron discharge valves and oscillators. STANDARD TELEPHONES & CABLES, Ltd. April 4, 1941, No. 4507. Convention date, May 11, 1940. [Class 39 (i)] In a high-frequency valve of the kind in which a cathode, control grid, and anode assembly is contained in a conducting envelope forming a resonant cavity output circuit provided with means for extracting energy from it, the envelope is in the form of a hollow toroid having a circumferential gap in the inner wall, and the electrode assembly is arranged co-axially with the toroid within the inner wall. In the form shown in Fig. 1, a flat anode 2 is sealed to the inner wall of the toroidal conducting envelope 1 at one edge of a circumferential gap in it, and a grid 5 is conductively secured to the wall at the other edge and tubular member 3 attached to the anode forms a capacity coupling between it and the envelope. The cathode 6 is indirectly heated. In a modification, the grid is insulated from the envelope and capacitively coupled to it by a tubular supporting member, the anode being directly connected to the envelope or coupled to it as in Fig: 1. In other forms a cylindrical anode with a closed outer end, a helical wire grid and a hairpin cathode, as shown in Fig. 5, are employed. The gap in the inner wall may be closed by a glass seal so that the space between the inner and outer walls of the envelope need not be exhausted. Fig. 5 shows an amplifier tube employing two resonant chambers, the chamber 11 being capacitively coupled to the cathode leads 12 and the chamber 1<11> to the anode 16, the grid 15 being at the potential of the outside of the chambers (earth). Signals are supplied to the lower chamber and amplified signals obtained from the upper. Specification 537,836 is referred to. The Specification, as open to inspection under Sect. 91 also describes the tube shown in Fig. 2 (Cancelled), comprising an annular grid 2 sealed to the envelope and coupled to it by flange-like members 3, an annular grid 5 directly connected to the envelope, and an annular indirectly-heated cathode 6.
