Patent GB-747892-A (GB)
Abstract: 747,892. Starting prime-moulds; generating arrangements. FOXCROFT, R. C. March 30, 1954 [April 2, 1953], No. 9293/54. Drawings to Specification. Class 38 (4). Electric lighting plant comprising an alternating current generator driven by a diesel engine which is automatically started up in response to demand for load, includes an independent battery-operated electric motor which starts up on completion of the load circuit and drives a multi-contact cam switch to effect the following sequence of operations: (1) energization by the battery of a solenoid for relieving the engine of compression; (2) connection of the battery to D.C. windings of the generator, so that it motors and cranks the engine; (3) deenergization of the compression-relieving solenoid to allow the engine to become free-running and start driving the generator; (4) disconnection of the battery from the generator; and (5) de-energization of the switch-driving motor. The independent motor may be of the reciprocating or pulsating type, so as to impart a stepby-step movement to the cam shaft of the switch; alternatively, a connecting rod driven by a crank from a rotary motor may operate the cam-shaft through a pawl and rachet mechanism. When the generated A.C. voltage attains working value it actuates a contactor to connect the generator to the load terminals over the winding of a load relay, as well as to interrupt the supply to the independent motor and to connect the D.C. terminals of the generator to the battery for charging. If the load circuit is now interrupted, the load relay falls out, causing the independent switch motor to re-start and effect (1) de-energization of the contactor to disconnect the generator from the load terminals, (2) energization of a fuel cut-off solenoid, (3) decompression of the engine, and (4) disconnection of the switch motor. A switch, responsive jointly to rotation of the camshaft and to pick-up of the contactor, and in circuit with the switch motor shuts down the plant if the generator does not build up its working voltage after a given number of starting attempts.

Patent GB-2004149-A (GB)
Title: PCM codec using common d/a converter for encoding and decoding
IPC: H03M1/00
Filed: 1978-08-22
Abstract: A coder/decoder in a PCM communications system, employs a common digital-to-analog converter. In a basic sampling interval the incoming PCM signal is decoded at a decision level on one side of the desired reconstruction level; then modified and again decoded at a different decision level on the other side of the desired level. The average of the two decoded signals then lies on the desired level giving a decoding characteristic having decision levels between those of the encoding characteristics. As used in a conventional PCM system, the two PCM samples differ by only one least significant bit. In a preferred embodiment, separate storage registers R1 R2 are used for encoding and decoding, plus a selector 262 for switching between the two registers during the decoding intervals. Thus, encoding may be effected during a substantial portion of the basic sampling cycle, being interrupted only to generate decoded samples. The invention is applicable to PCM systems generally, including compressed pulse code modulation systems. <IMAGE>
