Abstract: 1,145,304. Shift registers. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. 3 Feb., 1967 [7 Feb., 1966; 16 March, 1966], Nos. 5290/66 and 11590/66. Heading G4P. The flow of power fluid in a fluid amplifier is controlled by control pressure signals which are of such low pressure that they are only capable of switching flow from one wall to the other when the pressure of the power fluid is not greater than its minimum wall attachment value, and the power fluid is supplied in pulses so that the control signals can effect switching during those periods when the power fluid is at or below its threshold pressure. Fig. 4 shows the invention applied to a shift register in which a shift gate G has its outputs 36, 37 coupled to a memory M providing 0 and 1 read-outs at parts 40, 42 which communicate via constrictions 45, 46 with the control passages of another shift gate G1. The inputs S are fed with sawtooth oscillating pulses, and input P is connected with a steady pressure source. In a modification (Fig. 5, not shown) the impedance resulting from constriction 45 is replaced by moving the control nozzle (59) sufficiently downstream. Fig. 6 (not shown) illustrates a shift register having four amplifiers in cascade each receiving alternating power fluid pulses from the output of a fluid oscillator.

An analogue input current is supplied to winding 11 of a bi-stable magnetic core 9 so as to drive it towards one predetermined state, a step-wise variable reference current is supplied to winding 10 so as to drive the core towards the opposite state, and interrogating pulses are applied to winding 15 so as to drive the core towards the predetermined state and to provide an output pulse in winding 19 when the reference current just exceeds the analogue current. The sampling cycle is commenced by applying a pulse to flip-flop 20 to open gates 7, 17 thereby allowing clock pulses to reach counter 1 and delayed clock pulses to reach winding 15. Counter 1 comprises seven transistor flip-flops the outputs of which provide a binary-coded indication of the analogue current and are connected together through weighting resistors to provide the reference current. The output pulse from winding 19 switches over flip-flop 20 so that no further advance of the counter occurs.

Title: Process and machine for forming glass beads on wire
IPC: H01J9/32
Filed: 1947-02-27
Abstract: 621,666. Metal-to-glass seals; electric cables. STANDARD TELEPHONES & CABLES, Ltd., and FITCH, C. K. Feb. 27, 1947, No. 5684. [Class 36] A method of forming bead seals on wire comprises heating a portion of the wire, rotating the wire whilst feeding thereon a thread of molten insulating material (such as glass) which is then shaped, by centrifugal action or otherwise, under continued heating. The wire may be fed, step by step, in a continuous length, to form the inner core of a concentric conductor, the spaced beads constituting the insulation. As shown in Figs. 1 and 2, the wire is fed from a reel 1 through a driven hollow shaft 3 by a one-way reciprocating chuck 7 to gas jets 12, 13. Between these jets the wire passes under an electrically-heated die 15 in which a glass rod 17 is melted, a thin thread 19 of the molten glass being gravity-fed to, and coiled around, the rotating wire. In the succeeding forward movement of the wire, the coiled glass is heated by the jet 13. In this operation the glass automatically assumes spherical shape, but a shaping-die may be embodied at this stage if a special form of bead is desired. Finally, the bead arrives over a cooling-jet 14. Any surplus glass between the beads is removed by means of light hammers 21 actuated by cams on a countershaft 6. Fig. 4 shows a modification in which separate pieces of wire are assembled in chucks 23 ... 27 rotatably mounted in a jig-plate 22 which is given stepby-step rotation to bring the chucks into registry with heating-jets 28, 29, 30. In the position of the chuck 27, the beaded wire is ejected. The beads may be formed of material such as polystyrene or polyethylene; and, when used as insulators for coaxial cables, the beads are preferably die - formed into disc shape.

The switch comprises a body member 1 which has a top plate 2 receiving a lamp holder assembly (Fig. 1, not shown). A plunger (Fig. 1, not shown) is inserted in the body member 2 and can move parallel to the axis of the body 1. The part of the plunger above the lamp holder assembly may consist of a hollow knob (14). Magnetically operable electrical contact units 36 are arranged within the body member 1 to be operated by the annular permanent magnet 25 on movement thereof from the non-operated to the operated position. The magnet 25 is magnetized in its axial direction and secured to a lower cross-member 9 of the plunger and provided with a ferrous metal polepiece 28 of rectangular shape but with a quarter circle segment removed at each corner of the rectangle. A U-shaped keeper plate 20 of ferrous metal is rigidly supported at a predetermined height above the base member 17 of the body 1. The plate 20 lies in the space between the upper and lower cross-members, respectively 8, 9 of the plunger. A spring 31 is effective to bias the plunger, magnet 25 and polepiece 28 towards the non- operated position of the switch. In the latter condition the lengths of the air gaps 34 and 35 between the free ends of the legs of plate 20 and polepiece 28 essentially depends upon the thickness of the washer 33 which is a spacing piece for the magnet 25. The washer 33 may be secured to the magnet or to the keeper plate 20. Up to four reed contact units 36 may be located within the body member, one at each corner, so that each unit enters into the quarter circular cut out at a corner of the polepiece 28. The units 36 are connected by wires to the lamp holder. By actuating a knob (not shown) coupled to the plunger the magnet 25 is moved away from the keeper plate 20 and the reed contacts 36 are operated by the magnet 25.
