Abstract: 1,204,723. Capacitor-type detonating apparatus. BLANICKE STROJIRNY NARODNI PODNIK. 2 Sept., 1969, No. 51903/67. Heading H2H. In detonating apparatus comprising a capacitor 4 which is charged through a diode 3 from a crank-actuated A.C. generator 1 and is discharged through the firing circuit terminals 20, 21 by closure of a switch 5, there is provided a three-pole three-position switch 2 through which the generator 1 may be connected to the capacitor circuit or to a circuit for measuring the resistance of the firing circuit connected to terminals 20, 21. As shown, a tapping from the generator 1 is connectible through contacts Ia or Ib to a circuit comprising a rectifier 10, filter and voltage stabilizing members 11, 15, 16 and a bridge circuit formed by resistors 18, 19 and 13 or 14, by the resistance between terminals 20, 21 and by a conventional ohmmeter 12. Movement of the switch 2 to position Ia or Ib selects either resistor 13 or 14 to provide a desired measurement range. Movement of the switch 2 to the position II connects the generator 1 to the circuit comprising members 3, 4, 6, 7, 8. In a simplified arrangement, Fig. 1 (not shown), the ohmmeter (12) is a single range crossed-coil type and the switch (2) is two-pole, two-position, since the bridge circuit and voltage stabilizing members are omitted. The generator 1 may be replaced by a D.C. battery provided with a transformer to step up the voltage applied to the capacitor 4.

Abstract: 1404999 Supply systems for fluorescent tubes LEEDS EMERGENCY LIGHTING Ltd 14 Jan 1974 [29 Nov 1972] 55144/72 Heading H2H [Also in Division H3] An inverter for supplying a fluorescent tube 1 from a D.C. source comprises a transformer, the primary winding 2 of which is connected in the collector emitter path of a transistor 5, a capacitor 7 being arranged to be charged from the D.C. source by way of a resistor 6 such that, at a given capacitor voltage the transistor 5 conducts to energize the winding 2, which induces a current flow in a secondary winding 3 of the transformer causing an increase in the transistor current until the transformer core saturates when the transistor 5 turns off so inducing a high voltage in a further secondary winding 4 of the transformer to ignite and supply the tube 1, the cycle repeating when the energy in the transformer winding 2 has been dispersed. The drive current for the base of the transistor 5 is taken from the output voltage of the transformer by way of a diode 11 so allowing the resistor 6 to be of a very high value to reduce the drain on the D.C. source. A capacitor 8 improves the wave form of the current in the tube circuit and the capacitor 15, resistors 12, 13 and switch 14 allow the illumination from the tube 1 to be varied. In other embodiments a further winding, in series with a diode, may be provided in the transformer to recover any energy not used by the tube 1, the capacitor 7 may be omitted to give instant starting and the element 12-15 may be replaced by a single resistor when dimming of the tube 1 is not required.

Abstract: 1,243,675. Cathode - ray tube systems. FERNSEH G.m.b.H. 27 Nov., 1968 [27 Nov., 1967], No. 56358/68 Addition to 1,227,869. Heading H4T. In a colour television camera employing a plurality of pick-up tubes of the charge storage type together with dichroic elements supplying respective colour components of the image forming light to the photo-cathodes of each tube via respective secondary optical systems, light sources of controllable intensity are introduced between each such optical system and its associated tube to provide uniform illumination of the photo-cathodes. This illumination, which is additional to the image forming illumination, overcomes defects due to " persistence " in the photo-cathode of such tubes when operated at low brightness levels. Fig. 1 shows the general arrangement in which image light from a main objective lens 1 is directed via an intermediate objective lens 3 towards a beam splitting system comprising dichroic elements 4, 5 and mirrors 8, 11 and thence, as component colour beams (e.g. red, green and blue), via respective secondary objective lens systems 6, 9, 12 on to the photo-cathodes of pickup tubes 7, 10, 13. Between each secondary lens system and its associated tube the light sources, comprising four lamps (only three shown) 14, 15, 16 are positioned by means of the structure shown in Fig. 2, which comprises, for each source a ring member, 22, 23 fitted to the secondary lens systems and around the internal periphery of which the lamps (e.g. 24, 25) are arranged so as to illuminate a ring 26 of translucent, opalescent material which diffuses the light and produces uniform illumination of the photo-cathode of the pick-up tube 27. If desired, a screen or extensible bellows may be provided between the secondary lens and the tube to contain stray light. When the camera employs four pick-up tubes (i.e. three colour tubes and a luminance tube) the illumination of the photo-cathodes is effected by means of a lamp 37 (Fig. 3) the light from which is directed to the luminance tube 36 by reflection at the semi-silvered surface 33 of a beam splitter 32. The transmitted light is then reflected by a mirror 34 into an optical system 35 forming the intermediate lens system (such as lens system 3, Fig. 1) of the colour tube assembly.
