Patent GB-610653-A (GB)
Title: Improvements in or relating to electric pulse communication systems
IPC: B65B9/20
Filed: 1946-04-12
Abstract: 610,653. Pulse modulation. STANDARD TELEPHONES & CABLES, Ltd. April 12, 1946, No. 11329. Convention date, April 17, 1945. [Class 40 (v)] The signal-to-noise ratio of time-modulated pulses is improved by reducing the time displacements of the pulses to increase the time during which energy occurring between the pulses may be blocked. The time displacements of pulses may alternatively be increased after a blocking operation and in each case the change is produced by demodulating the pulses and using the resulting signal further to time modulate the modulated pulses. In one embodiment, time-modulated pulses in the output of a radio receiver 1 are passed to the demodulator 26, low-pass filter 27 and earphones 28, through a modulator 18 and amplifier 25. The demodulated signal output from filter 27 is also passed through a phase inverter 30 and variable-gain amplifier 31 to time-modulate the pulses passing through unit 18, by varying the value of the inductance 20 of a delay line as described in Specification 593,101. In this circuit the time-modulation range is reduced so that the gating pulse generator 34 and shaper 35 can be set to produce longer blocking pulses for application to amplifier 25. In another embodiment, Fig. 3 (not shown), the time-modulation range is increased after the incoming pulses have been gated by amplifier blocking pulses of the maximum possible duration. To this end, the phase inverter 30 is omitted, the amplifier 25 precedes the modulator 18, and its blocking pulse generator is controlled by the output of the latter.

The strips may be of paper, unwoven fabrics or woven fabrics, foils of metal, cellulose derivatives, thermoplastics, thermosetting resins, rubber or organo-fluorine containing polymers or molecularly oriented polymers. Each of the tubes may be formed by wrapping the constituent strip or strips in helical fashion with the edges overlapping and a compressive force may be inserted upon each strip while it is being wound on its mandrel in such a manner as to wind the strip about and move it along the same. A variety of methods of exerting this compressive force are specified (see Division F2) and the force may be such that a permanent shaping of the strip results. The tubes are preferably formed with their axes in a common plane and the block is formed by moving the tube section in layers transversely to this plane. A material constituting a precursor of a hardenable bonding material may be applied to the tubes prior to the connection of their end regions to already separated tube sections, e.g. by spraying and in one embodiment the mandrel in which the tube is wound is provided with an internal duct for supplying bonding material to the inner surface of the tube to be wound. The blocks may be cut into panels by means of saw blades 31 or electrically heated wires. The panels 30 may be inserted between facing sheets.

Class 64(2) In a trap in which condensate at an inlet passage 48 tilts a loose valve plate 53 (which may be rectangular, Figs. 19, 20, not shown, or circular) to flow through a control chamber 42 to an outlet 51 but in which gas or vapour flowing in the same manner creates a relative pressure in the chamber to seat the plate 53 in the position shown, the plate has an annular groove 57 or the seat has an oval or annular groove 58, or intercommunicating annular grooves 58<SP>1</SP>, 58<SP>2</SP>, Fig. 18, or they each have a groove; there is also continuous leakage from the chamber 42 to the outlet 51 in the seated position. The leakage path is provided by a comparative roughness of the plate and seat surfaces surrounding the grooves 57, 58, by a radial groove in one of those plate or seat surfaces, Figs. 11-14 (not shown), or by a hole (partly closed by a piece of wire if necessary) through the plate 53 to its groove 57, Figs. 15, 16 (not shown). Any leakage past the inlet seat 55, which may also be comparatively rough-ground, passes through one or both of the annular grooves 57, 58 to the outlet 51 so that there is no leakage to the chamber 42 to keep the plate 53 seated. In Fig. 18 there is a hole 75 providing extra communication to the upper part of the control chamber when the plate 53 is unseated. As indicated by Fig. 18, the valve seats may be formed on a separate removable piece 34 which may be fitted with an inlet sleeve 46 and rests on a washer at the bottom of a cavity in the trap body, being held in position by a washer compressed in a wedge groove (formed by a shoulder 38 and a corresponding shoulder in the cavity) by an annular flange extending from the cap 40, Fig. 10. In one form, Fig. 21 (not shown), there is a drainage bore from the groove 58 to the annular space between the seatpiece 34, the wall of the body cavity and the washers. The trap may be of steel or bronze and the cap and body may be of one stainless steel and the valve plate and seat of another. As shown in Fig. 10, there may be a groove 63 around the seat, so that the fulcrum of the plate 53 (at the left-hand side of the Figure) is at the edge of the groove and the plate may have a groove 65 to fit over. the edge when tilted. To provide a line fulcrum instead of a point fulcrum for a circular plate 53, the seat edge at the left-hand side may be bevelled, Figs. 21-26 (not shown), to give a surface with a fulcrum edge and the plate may be permitted to tilt sufficiently to move at a later stage about a second fulcrum at the extreme edge. The bevelled surface may be curved to give a gradually changing fulcrum edge as tilting proceeds.
