As described, impedances 48, 60 are resistors, but alternatively inductances may be used, and resistor 62 may be shunted by a capacitor. The switching circuit may be used in conjunction with similar circuits 152, 154 to control a single load transistor 156, isolation being provided by backward diodes 116, and may also, or alternatively, control a number of parallel connected load transistors 156, 158, 160.
Patent GB-375115-A (GB)
Title: Improvements in and relating to transmission devices
IPC: F16C1/20
Filed: 1931-07-31
Abstract: 375,115. Hinges. CORSET, L. A. M., 29, Boulevard de Grenelle, Paris. July 31, 1931, No. 21938. Convention date, Nov. 18, 1930. [Class 65 (ii).] A flexible cable for transmitting push or pull movements, guided in a lubricated metal tube, comprises a tension transmitting core 4 consisting of one, three, four, seven or nineteen untwisted or only slightly twisted metal strands, mounted in a compression transmitting member formed by a series of tubular parts 3, spaced by, and spherically seated in barrel-shaped parts 2 which have truncated conical recesses in their ends to permit the necessary angularity of the tubes. Each tube 3 may be integral with a barrel 2 which may have a curvature corresponding to that of the guide tube. As shown in Fig. 9, the end of the core 4 is fixed to a sleeve 11 which screws, to take up play between the tubes and barrels, into a terminal part 7 carrying a hinged cap actuated by an operating lever. A half barrel 13, with an interposed lock-nut if desired, is placed between the last tube 3 and the terminal part 7. The playreducing screwing of the sleeve 11 may be made automatic by twisting the core to impose a torsional force on the sleeve. In a modified non-adjustable terminal arrangement the sleeve 11 is formed by the last tube 3 which acts only to clamp the end of the wire core which is either tin-soldered to it or its ends are splayed over a loose ball in the terminal part 7. Several lengths of cable may be joined by using screwed sleeves in place of the terminal parts 7. The Specification as open to inspection under Sect. 91 (3) (a) states also that the compound cable may be used without the guide tube as a rod of adjustable rigidity for supporting and also supplying current to electrical apparatus. In this case, the conducting core 4 is electrically insulated and the rigidity of the rod is varied by spacing the last barrel from the terminal part 7 by means of a nut or eccentric thus applying more or less friction at the joints. The tubes 3 are reduced in length almost to spherical shape and are made of friction material. In the tube-guided form the barrels may be cylindrical and of hard metal. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to starter, dynamo, and ignition units for internal combustion engines
IPC: F02N11/08
Filed: 1926-09-11
Abstract: 278,499. Greaves, R. Sept. 11, 1926. Driving-arrangements.-A combined starter, dynamo and ignition unit for an internal-combustion engine comprises a dynamo-electric machine in which the field is rotated at starting in the reverse direction to that of the armature through a clutch and planetary or other gear, the field and gearing being stationary when the machine operates as a generator. Upon the crank shaft C is mounted a slidable splined clutch member D carrying a portion D' of a dog clutch adapted to engage another clutch member D<2> carried by a planet plate P surrounding a boss. E<1> of the fixed casing E. The member D is slidable on but not rotatable relatively to the splined armature shaft A and has a pin H which engages with an inclined slot K in the shaft C. A star wheel P<2> carried by the casing E gears with teeth P<1> on the planet plate and with a wheel P<3> on the field frame. The clutch elements D<1>, D<2> are normally kept out of engagement by a spring D<3>, but at starting, a limited movement of the armature causes the. member D to be moved against the action of the spring and the field is rotated through the planetary gear. As soon as the engine fires and overruns the motor, the pin H moves back along the slot K and the clutch is disengaged. Rotation of the field is prevented by an arm F<5> engaging with a ratchet F<4>. The arm P<5> is pivoted at F<6>, and has another arm F<7> which at starting is raised by a cone F<8> carried by the clutch member D so that the field is free to rotate in the reverse direction in the event of a backfire. Starting may be effected by cranking from the end A<3> in which case the machine acts as a generator and supplies the ignition coil. The ignition coil and distributor unit Bare operated by a worm pinion W keyed to the crankshaft. A magneto may be employed. The main commutator brushes carried by the field frame are connected to slip rings R, R<1>. If a combined permanent magnet and electromagnet field be employed, the exciting brush may be arranged to be raised automatically on reversal of field rotation due to a backfire at starting.
