Title: Method of and apparatus for the high speed transmission of data on telephone lines
IPC: H04L25/48
Filed: 1968-03-21
Abstract: 1,215,745. Digital transmission systems. SOC. ALSACIENNE DE CONSTRUCTIONS ATOMIQUES DE TELECOMMUNICATIONS ET D'ELECTRONIQUE. 21 March, 1968 [22 March, 1967], No. 13728/68. Heading H4P. Serial binary data is transmitted over a telephone line by single side-band technique. The frequency spectrum is level over this band. Transmitter, Fig. 2 (not shown).-Unipolar binary input data B, Fig. 1, at bit rate 2s is sampled by clock pulses G to produce a signal G.B. The inverse of the data, B, is similarly sampled to give G.B. The latter signal is polarity inverted (- G.B.) and added to the other sample signal, the resultant polar signal being as S. Signal S is filtered in a unit comprising several tuned LC circuits in parallel, Fig. 3 (not shown), the unit having a pass-band s to 2s, so giving signal SI. This amplitude modulates a carrier of frequency f + 2s, and a low-pass filter selects the lower sideband of width f to f + s for transmission over the time. A pilot signal accompanies the transmitted signal and lies above frequency f + 8. Receiver, Fig. 5 (not shown).-The pilot frequency is extracted from the received data and from it, by multiplication, mixing, and filtering, are derived frequencies 2s, f + 2s, and clock signals T + , T-, Fig. 4. The A.M. signal is filtered, and demodulated with the frequency f + 2s. The demodulated signal is passed to a filter having a pass band below 2s, its output being as S<SP>1</SP>1. This signal is split into positive and negative parts S+, S-. Signal S + is gated with T + to give B + and S- with T- to give B-. Signals B +, B- control a bi-stable unit which develops a signal R identical to that, B, at the transmitter input.

Filed: 1940-06-01
Abstract: 592,833. Fluid-pressure servomotorcontrol systems. LUCAS, Ltd., J., and WATT, J. L. June 1, 1945, No. 13824. [Class 135] The output of a liquid fuel pump, e.g. of the swash. plate type, is controlled by a spring-loaded piston q subject on both sides through a restricted passage tc the outlet pressure of the pump and disposed in a cylinder having an outlet u to a sump or the pump inlet controlled by a pivoted closure v disposed in a chamber 6 having an outlet 7, Fig. 2, to the sump controlled by a pivoted closure 8. By this arrangement, if closure of the outlet u is obstructed, the outlet 7 can be closed to permit functioning of the control. The closure v is carried by an arm 9 fast on a spindle 10 projecting through a wall of the chamber 6 and carrying a second arm 11, while the closure 8 is mounted on a lever 12 supported on pivots 13 coaxial with the spindle 10, the arm 11 and the lever being spring-loaded to hold the closures against their seats. Opening of the closures 8 is effected by a stop 2 on a spring-loaded diaphragm z subject on its outer side to, e.g. the oil pressure in the pump casing b, and on its inner side to the pressure in the oil inlet duct i. The pressure in the casing b is built up by a centrifugal pump formed by the axial and radial passages m, o respectively in the pump body a.

Class 87(2) An open-turn winding 6a, Fig. 2, of thermoplastic strip, which is to form the whole or part of the insulation between the two conductors of a coaxial cable, is applied to a continuously-travelling inner conductor 1 by (a) drawing the-strip from a rotating source of supply and preforming it, in the cold state, into helical form in a forming guide 28; (b) presenting the helical strip under low tension or without tension to a rotating helical mould 28a that is concentric with and opens into a passage through which the conductor is drawn; (c) softening the strip by heating it in the mould; and (d) cooling the winding as it is drawn from the mould by the conductor. As shown, the forming guide 28 and the mould 28a are integral parts of a mandrel having a continuous helical radial slot 30 which begins at 31 and ends at 32 where it emerges into the end face of the mandrel. The mandrel has an axial bore 29 for passage of the conductor, is supported by bearings 36, 53, and is surrounded at its centre by a steam-heating jacket 40 and at its discharge end by a cold-water jacket 35a. The bearing 36 is water-cooled to prevent transmission of heat from the heated part of the mandrel to the preforming part 28. The conductor 1 is drawn from a spool 3, Fig. 1, travels straight through the mandrel, and is wound, with the helical strip thereon, onto a capstan 2. The mandrel is fixed to a shaft 22 rotated by an electric motor 9 via chain 10, shaft 11, chain 12 and gears 13, 14. A strip supply reel 21 is loosely mounted on shaft 22 and is rotated, under the control of a friction brake, by the pull of the strip 6 as the latter is being wound into the slot 30. The strip passes from the reel to the slot via rollers 25, 27, 26. The cold water supply comprises a manifold 38 having branch pipes 37, 51, and the steam supply comprises a manifold 45, 44 having branch pipes 42, 43 and an exhaust 54. Steam pipe 45 leads into cold water pipe 44, and to ensure that steam and cold water will not be led simultaneously into the heating jacket 40 a mechanical linkage 57 may be provided between valves 46, 47. Another linkage 56 having a similar function is provided between valves 46, 55. The capstan 2 is rotated by the motor 9, and relative speed control as between the capstan and the mandrel is obtained by gear boxes 19, 20.

[Class 38 (v).] A switch for preventing unauthorised use of motor-cars has a movable contact p mounted on an insulating disc m secured on a central rotary spindle, the disc m being provided with a number of tapering holes n. Co-operating with these holes are the conical ends e of a series of spring plungers c which bear numbers or letters in such a manner that after the switch has been set in its normal open-circuit position it is necessary in order to bring the contacts into engagement to press plungers in order of a code word or combination, each plunger by the reaction of its end c with the side of the corresponding tapered hole n moving the disc around slightly until finally the contacts p, q, are brought into engagement and the ignition &c. circuit closed. The contact disc is brought to its normal open-circuit position by pressing plungers in reversed sequence of the code word or combination. The rotation of the disc is limited by cut-away portions r co-operating with securing bolts of the switch structure. In an alternative construction the spring plungers are arranged in line and operate a sliding bolt or bar switch.
