Abstract: 390,815. Electric-lamp holders. OS, J. L. VAN, 87, Inverness Terrace, London. Oct. 8, 1931, No. 27995. [Classes 39 (ii) and 75 (iii).] To exclude moisture from the joints between the ends of adjacent units in a flexible chain of hingedly connected rigid electric lamp-carrying units, the interlocking ends of the unit are held by a screw which tightly draws the parts of the joint together. As shown in Figs. 1 and 2, the unit comprises a moulded strip 1 of synthetic resin formed with a single eye 4 and double eyes 5, 6 on opposite ends of the strip and carrying a screwed lamp-holder 10. Wire conductors 2, 3 are embedded in the strip and terminate in loops on the surfaces of the eyes 4, 5, 6, as shown. The conductor 2 is connected to the lamp-holder 10 whilst the conductor 3 is bent to form a lodgment 11 for the centre contact of the lamp. The eye 4 is adapted to be inserted between the eyes 5, 6 of an adjacent unit, a screw 7 of hard insulating material being passed through the eyes 5, 4 and engaging a thread in the eye 6 to draw the joint tightly together. To permit the chain of units to be carried round sharp bends, the strip 1 is formed with bevelled edges 8, 9 adjacent the eyes 4, 5, 6. In a modified construction the strip 1 is built up of parts, grooved to receive the conductors 2, 3 which may be of strip form, and secured together by rivets. Holes 12 may be formed in each unit for fixing purposes, the conductors 2, 3 being bent or apertured to clear the holes. Fig. 4 shows a further modification in which the lamp-holders are formed by the eyes at the ends of the units. The lower eye of the double-eyed end is threaded to receive the lamp cap whilst the upper eye and single eye are formed with clearing holes, so that the joint between two units is tightly drawn together by screwing in the lamp. The upper conductor 2 makes contact with the lamp cap whilst the lower conductor 3 is carried clear of the cap through a space 13 to contact with the centre terminal of the lamp. The units may contain one, two or three conductors, depending on whether the lamps are to be connected in series, parallel, or to a three-wire system. Branches in the chain of units may be made by a right-angle unit having single- or double-eyed centre connections.

Patent GB-750000-A (GB)
Title: Party line telephone systems
Inventor: SCOWCROFT JOHN
IPC: H04Q5/06
Filed: 1952-11-07
Abstract: 750,000. Party-line systems. GENERAL ELECTRIC CO., Ltd. Sept. 29, 1953 [Nov. 7, 1952], No. 28105/52. Class 40 (4). A system as described in Specification 749,998 is modified to enable a party-line subscriber to make a revertive call without departing from the normal calling procedure, each substation being provided with a cut-off relay which breaks a calling subscriber's D.C. loop on the arrival of a revertive ringing condition. To make a call, a subscriber lifts his receiver, closing cradle contacts CS1 and CS2, and, if no call is already in progress on the line, depresses a push-button having contacts AL1 and AL2 which thereupon latch in the operated position under the control of the cradle. The caller then dials the wanted number. If the call is a revertive one, the selective ringing signal described in Specification 749,998 is modified in that the high potential is applied to one line wire a short time ahead of the. A.C. which actually rings the bell. At the calling substation this high potential fires a gas tube NT1 or NT2 and operates a relay B which breaks the D.C. calling loop, although the caller can still hear ringing signals via a condenser C1. The wanted subscriber's bell is rung following the firing of his gas tube NT3 and the operation of his relay A, as described in Specification 749,998. If he replies, the completion of his loop trips the ringing, releasing the calling subscriber's relay B to complete the talking connection. If the called subscriber does not reply, the unlatching of contacts AL1 and AL2 when the calling subscriber hangs up completes a momentary loop during the delayed release of relay B, providing a clearing signal to the exchange apparatus which then frees the line when B completes its release.

Title: Improvements in or relating to radio transmitters
IPC: H03F1/54
Filed: 1963-07-19
Abstract: 1,006,200. Valve supply circuits; transistor pulse circuits. SIEMENS & HALSKE A.G. July 19, 1963 [July 19, 1962], No. 28678/63. Headings H3T and H3W. In a " fail safe " automatic switching-on arrangement for an air-cooled valve transmitter, sequential switching is effected in response to the appearance of control signals at the outputs of three AND gates. The inputs to these gates comprise indications of the state of the transmitter, being determined by a sequencing arrangement formed of control circuit assemblies built from diodes and transistors. Switch-on occurs in three stages, viz. (1) warm-up, (2) operation at one third full power, and (3) full power, and involves the energization of separate blowers for cooling both directly and indirectly heated valves, supply of valve heater current-effected by switches operated by the cooling air-the initiation of anode, screen-grid and bias voltages, and also the start of H.F. drive, all with appropriate time delays and in correct sequence. At each step any malfunctioning either causes the switching-on sequence to be interrupted or, if necessary, shuts the transmitter down. The Specification discloses and describes the manner of operation of a suitable circuit (Fig. 1, not shown); details are also given of the control circuit assemblies used therein, comprising double and single AND gates, a double inverter stage, a trigger timing circuit, an auxiliary delay circuit and a memory circuit (Figs. 2a-2f, respectively). In the double AND gate, a negative bias is applied to terminal N, Fig. 2a, so that it produces a negative-going control signal at output terminal X1 only when negative potentials are applied to all of the input terminals 11, 12, 13, and likewise at terminal X0 only when negative potential is applied to all the input terminals O1, O2, O3. The single AND gate (Fig. 2b, not shown), is similar but comprises only a single input and output. Each of the remaining control circuit assemblies is either identical with corresponding circuits shown in Figs. 4a-4c, and 4f of Specification 991,949 or differs only in the number of alternative input terminals provided.
