An ignition device for an internal-combustion engine includes a generator comprising a rotor and a stator and a main winding 10 and an auxiliary winding 11 interconnected in series by an intermediate terminal which is connected to one terminal of a capacitor 17 whose other terminal is connected to a primary winding 12 of an ignition coil. The capacitor is charged from pulses produced in the main winding and the device further comprises a controlled rectifier 15 in parallel with the main winding. The control electrode of the controlled rectifier is connected to the auxiliary winding 11 and the controlled rectifier is controlled by pulses produced in the auxiliary winding to discharge the capacitor by way of the primary winding. In a modification the diode 18 is connected across the controlled rectifier.

Abstract: 1,250,688. Two-part coupling. SIEMENS A.G. 8 Oct., 1969 [9 Oct., 1968], No. 49485/69. Heading H2E. In a multicontact connector for connecting to strip conductor layers 11 carried by insulating foils, one of the foils 9 acts as the plug-in member whilst the other 4 is arranged so that its conductors form the contacts of a socket and are pressed into contact with the plug conductors through a spring member 3 which is acted on through a spring clip 6 or through a cam (13, Fig. 3, not shown). The socket body is held together by springs 2 or by side plates (14). The foil 4 is secured to spring 3 together with a backing strip 5 and may be separated from the strip by a resilient support (16). The spring 3 is sectioned into strips such that each strip only covers two plug contact strips thereby allowing uniform pressure to be exerted on all contacts should irregularities exist in the plug contact surfaces. Locating plates (10, Fig. 1, not shown) may be attached to foil 9 and springs 2 to prevent relative movement of foils 4, 9.

Abstract: 1290086 Welding by fusion; cutting by fusion MESSER GRIESHEIM GmbH and SCHMALL AUTOMATION UND ELEKTRONIK MARGRIT SCHMALL 14 Aug 1970 [16 Aug 1969] 39322/70 Headings B3R and B3V During welding a cutting in which the distance of a torch 32 above the workpiece 14 is maintained constant by height regulating means controlled in response to detected capacitance between the torch and workpiece, normal height regulation is overridden when capacitance changes, due to the proximity of a workpiece discontinuity, would tend to cause height regulation. The welding or cutting apparatus includes a capacitance proximity detector 13, a torch 32, in series circuit with an inductor 12; the frequency of oscillation of oscillator 10 thus depends on the capacitance detected by detector 13. Output from the oscillator 10 is to a discriminator 15 which has two output lines 19, 20 to a differential amplifier 16. The latter outputs to a phase start control 17 controlling a height regulating motor 18 which drives a pinion 34 meshing with rack 33 on the torch. Also included are relay-operated switches 24, 25, 31; switches 24, 25 are connected to voltage dividers 28, 29 and batteries 23. Operation.-Changes of capacitance in the series circuit of oscillator 10 cause the frequency of the latter to shift from the centre frequency of discriminator 15; unequal outputs to amplifier 16 result, and the latter causes control 17 to operate motor 18 to restore the torch height to return the detected capacitance to its predetermined value. In order to prevent this height regulation when capacitance changes due to the proximity of a workpiece discontinuity (e.g. edge, corner, or hole), would tend to cause height regulation, an electrode signal of appropriate value and polarity is supplied to line 19 from the relevant divider 28 or 29 by closing of its associated switch 24 or 25. Thus the inputs to amplifier 16 are balanced, and no height regulation occurs. Where a corner of the workpiece is to be traversed, and height regulation has already been overridden while the torch traverses one edge while moving towards the corner, further overriding at the corner is provided by opening of switch 31 which cuts amplifier 16 off from control 17. The switch closures can be effected manually, or automatically where the apparatus is controlled by punched tape or photo-electric means. Where the apparatus operates in conjunction with a profile scanning device, switch 31 may be controlled from said device which monitors the pattern.
