Title: Improvements relating to automatic starting and re-starting mechanism for internal combustion engines
Filed: 1933-12-30
Abstract: 432,553. Starting prime movers. LUCAS, Ltd., J., and WATSON, E. A., Great King Street, Birmingham. Dec. 30, 1933, No. 36736. [Class 38 (iv)] An automatic starting system for an internalcombustion engine comprises a combination of three electromagnets, one of which serves to close the starting switch, the second to control the circuit containing the first electromagnet, and the third (responsive to starting motor current) to control a switch in the circuit containing the second electromagnet, together with means dependent on the motion of the engine for supplementing the action of the second electromagnet. The starter motor s is controlled by a switch a the solenoid circut of which is completed through a manual switch e and contacts i on a spring strip g which is moved to open the circuit when the electromagnet l operates. This electromagnet has two windings, one p connected across the generator q and the other k connected across the starter motor through a switch u operated by the starter motor current. This switch comprises a single turn r surrounding a core x. When the starting motor is taking a heavy current these contacts are open but when the current drops due to the engine starting these contacts close and complete the circuit of the winding k which causes operation of the armature l to break the circuit of the starting switch solenoid. This circuit is maintained open during normal running by the winding p being energized from the generator. Instead of the winding p any means responsive to engine operation to keep open the circuit of the starting switch solenoid such as a switch operated by the pressure in the engine lubrication or induction system may be used.

Abstract: 882,682. Electromagnetic interrupters; contact members for switches. BRISTOL CO. Nov. 20, 1958 [Nov. 22, 1957], No. 37351/58. Class 38 (5). A synchronous interrupter or " chopper " has two magnetic members defining two gaps with one end of an angularly-movable armature in one gap and the other end adjacent to but outside the other gap. Fig. 1 shows an exploded view of parts which are clamped on two insulated bolts 11, 12 and include the magnetic members 14, 15 on non-magnetic cross-arms 16, 17. A U-shaped non-magnetic frame 18 with forked ends is shown in two parts between the ends of which fixed contact assemblies 27 . . . 30 and armature tabs 52, 53 are clamped with suitable spacers 19 . . . 26 and insulation 31 . . . 38 on each side of the contact assemblies. The armature 13 is T-shaped and is formed of two identical sheets of iron with a thin sheet of resilient material such as nickel-iron sandwiched between them with the tabs 52, 53, projecting to form resilient hinges. The stem 50 of the armature passes loosely through a coil 60 which rests on the stacked components between the members 14, 15 and is surrounded and shielded by permanent magnets 61, 62 arranged with like poles adjacent the members 14, 15. Moving contacts 54, 55 are insulated from the armature and connections 58, 59 therefrom are held between studs 72 to prevent vibration. As shown in Fig. 2, the armature 13 extends into the lower air gap 104 but not into the upper gap 105 whereby a substantially linear relationship between force and deflection of the armature on coil energization is obtained. The frame 18 is riveted to a base 80 which is sealed to a non-magnetic case 83 having circular indentations 86 and 96 which engage and locate a resilient ring 85 which retains the magnets 61, 62 in position about the coil. Fixed contact assemblies (Fig. 8), each comprise a rigid part 286 with two transverse notches 284, 285 and a spring 282 carrying a contact 283 and riveted at 281 to the part 286. On assembly the part 286 is bent at notch 284 so that its end deflects and stresses the spring 282 and it is then bent at 285 to set the contact gap. A flexible non-magnetic strip 14A is riveted to the members 14, 15. This strip may be rigid if the gap 104 is lengthened by dispensing with the lower horizontal portions of members 14, 15. Specifications 802,758 and 882,684 are referred to.

Filed: 1975-09-11
Abstract: 1518155 Transistor oscillator SIEMENS AG 11 Sept 1975 [2 Oct 1974] 37494/75 Heading H3T In a HF oscillator, e.g. for surgical purposes, positive feedback across a transistor stage via a ferrite cored transformer is arranged so that prolonged off-load operation causes heating of the core past its Curie point, so reducing the coupling and the current through the transistor. The core, preferably in the form of a ferrite rod heated preferentially near its centre provides the coupling between windings 3, 4, their inductances with capacitors 4, 5 controlling the frequency around 1 MHz, the power output being taken from terminal 10 via capacitor 9 from between capacitors 4, 5. Foot switch 17 should switch off the oscillator when not required: the circuit protects the power transistor I from thermal damage in the event of switch 17 failing to switch off The maximum core loss occurs in the off-load condition (see equivalent circuit, Fig. 3 not shown) raising the temperature to the Curie point of 190‹C (Fig. 2 not shown), the sharp fall in relative permeability from about 400 to e.g. 100 causing a rise in frequency and fall in coupling, so driving the transistor I less hard.
