Filed: 1972-09-15
Abstract: 1386687 Image pick-up tubes; photo-conductive targets TOKYO SHIBAURA ELECTRIC CO Ltd 15 Sept 1972 42854/72 Headings H1D and H1K An image pick-up tube is provided with a signal pick-up electrode disposed on the peripheral portion of the target outside the scanned area, thereby reducing the capacitance of the target and its retention of residual images. The target shown in Fig. 3 comprises a photo-conductive layer 18 of cadmium selenide two microns thick deposited on the faceplate and covered with a layer 21 of cadmium selenite on which an insulating layer 20 of arsenic trisulphide is formed; the pick-up electrode 19 is an annular frame of tin oxide, aluminium, or tin and extends around the periphery of the target and round the edge of the layer 21. In modifications the layer 21 may be omitted (Fig. 2, not shown), and the electrode 19 may be flat and extend under the edge of layer 18 (Fig. 4, not shown). The layer 18 should have a resistivity between 10<2> and 10<10> ohm-cm. The resistive layer 20 may be of arsenic disulphide, zinc sulphide or selenide, germanium selenide, or antimony trisulphide. These targets are unsatisfactory when transmitting an image in the form of a black frame, and this disadvantage may be avoided by providing a conductive layer corresponding to the scanned area. The conductive layer may be provided on the inner surface of the faceplate (Figs. 6 and 9, not shown), and should be of complementary shape to electrode 19; where the latter is annular the conductive layer should be circular (Fig. 8, not shown), and when the conductive layer is rectangular the edges of electrode 19 should extend inwards to leave a rectangular opening (Fig. 7, not shown). The conductive layer may be covered with insulation (Fig. 13, not shown), or may be provided on the outer surface of the faceplate (Figs. 10 and 11, not shown). In another construction (Fig. 12, not shown), the inner surface of the faceplate is provided with a transparent conductive layer which forms the pick-up electrode, and this is covered with insulation over its central portion corresponding to the scanned area.

Abstract: 1396768 Ring-trip circuits PLESSEY CO Ltd 26 June 1973 [16 Sept 1972] 43040/72 Heading H4K In a ring-trip circuit which is connectible at X1, X2 to a two-wire line and which rings a magneto bell in series with a capacitor across the line, e.g. in a subscribers sub-station by applying a ringing current waveform to one wire and negative ring-return battery to the other wire, in the absence of a D.C. loopcondition at the line a sustained positive potential is generated at C2 from the ringing current waveform and this potential maintains a first transistor T1 OFF, whereas a second transistor T2 is switched ON and OFF by successive negative and positive half-cycles respectively of the ringing current waveform. Continuous ringing tone is applied to the circuit at CR to be replaced, after 300 ms., by intermittent ringing tone at IR. If the line is looped during a "silent" period, i.e. when earth is applied at X1, ring-return battery extended over the loop turns T1 and T2 ON immediately. After a delay, caused by C3 and R10, T3 is turned ON. With T2, T3 both ON, the gate comprising D5 and D6 is operated and T4 is switched OFF. Transistor T5 is accordingly driven to saturation and earth is introduced via T5 to whichever of relays CT, INT is currently operative, thereby releasing the relay and disconnecting the corresponding ringing current source. If the line is looped during a "ringing" period T1 and T2 are turned ON after a delay produced by R4, R6 and C1, and the above sequence occurs.

Abstract: 1,102,208. Transistor amplifying circuits. MOTOROLA Inc. 28 Sept., 1966 [22 Oct., 1965], No. 43391/66. Heading H3T. In a transistor amplifying circuit which comprises a number of PN junctions in cascade, bias is derived from a potentiometer one arm of which comprises a similar number of cascaded PN junctions, so as to eliminate temperature effects. The arrangement is shown applied to an amplifier comprising a Darlington pair 10, 15 with emitter circuit resistor 28 and output taken from a resistor 24 in the collector circuit of transistor 15, the input base bias is applied over a diode comprising transistor 34 with base and collector strapped. According to the invention the bias is derived from a potentiometer comprising resistor 32 and the baseemitter paths of transistor 42, which has base and collector strapped and transistors 47, 51 which are connected as a Darlington pair. As shown, the amplifier is biased for class B operation, but a resistor may be connected in the emitter circuit of transistor 51 to compensate for the effect of resistor 28, and resistor 32 replaced by a constant current source (Fig. 2, not shown). The arrangement is more particularly intended for integrated construction, one form of which is disclosed in the Specification.

The current increments are governed by an oscillator 10 feeding pulses through a binary counter 9 operating switches S1-S7 connecting a plurality of resistors R1-R7 arranged in a binary progression to a bridge network Fig. 2 (not shown). In a modification a known bridge incorporating temperature dependent resistors TH1, TH2 giving a linear characteristic over a range of temperatures is modified by resistors R21-R26 connected to switches S8, S9 which set the initial and final temperature values. In a refinement Fig. 5 (not shown) the resistors S1-S7 control the relative conductivities of a pair of differentially arranged transistors (TR1-TR2). The bridge may control a thyristor in series with a heater in a chromatograph oven. It is preferable, but not essential that temperature changes should be substantially linear with time and also desirable that changes at different times should follow the same law.
