Filed: 1971-12-23
Abstract: 1374260 Transistor switching circuits; protecting transistors against overload ITT INDUSTRIES Inc 23 Dec 1971 [29 Dec 1970] 59929/71 Heading H3T [Also in Divisions G1 and H2] A measuring instrument, e.g. an ohmmeter, comprising an indicating device MU and an operational amplifier A, which provides an output signal to the device, the signal being representative of a value (e.g. of resistance) applied between the inverting input and the output of the amplifier, is protected by a switch T connected between the inverting input and a D.C. source AL, and a detector DET connected to the output of the amplifier and controlling switch so that if the output of the amplifier is outside the potential range of the instrument the switch T is opened. The detector may comprise transistors Q1, Q2 connected in series with the coil of a relay RE across a supply + V, - V, the bases of the transistors being connected through resistors to the output S of the amplifier A. Should the potential of the output S go beyond + V or - V, then Q1 or Q2 respectively will cease to conduct so that the relay is de-energized and opens its contacts T. This would occur if the resistor Rx being measured has a value outside the range of the ohmmeter or if voltage is incorrectly applied to either terminal E1, E2. A resistor Rc may be connected across the contacts T to prevent cyclic operation of the relay RE should the resistor Rx have too high a value. A resistor/capacitor delay circuit may be provided in the detector DET to reduce the frequency of cyclic operation should it occur, e.g. due to the resistor Rc being short-circuited, Fig. 4 (not shown). A further switching circuit may be connected to the detector and arranged to provide a signal to the indicator MU to cause it to give a sustained high reading should the resistance Rx have a value outside the measuring range, Fig. 5 (not shown).

Title: Regulating Circuit for Discharge Devices.
IPC: H05B41/39
Filed: 1968-12-30
Abstract: 1,190,690. Supply circuits for discharge lamps. SYLVANIA ELECTRIC PRODUCTS Inc. 30 Dec., 1968 [29 Dec., 1967], No. 61738/68. Heading H2H. An operating circuit applies a voltage pulse to a discharge lamp once each half-cycle of the supply just sufficient to maintain conduction through the half-cycle. Means is also provided for compensating variations in supply voltage and lamp current. In the circuit shown, two lamps x are connected to an A.C. source by way of an autotransformer L1, L2 and a resistor R. Also connected across the supply terminals there is a timing circuit comprising a photo-conductor Rt and two capacitors C2, C3. In operation, voltage builds up at the junction j between the capacitors until a diac D1 breaks down and triggers a triac V1, allowing a capacitor C1 to discharge and supply a pulse through the autotransformer to the lanps. The lamp filaments are supplied from a transformer secondary T3, and a further secondary winding T2 serves to energize a lamp E, the light from which falls on the photo-conductor Rt. Thus, changes in the supply voltage alter the characteristics of the timing circuit and cause, for example, earlier pulsing of the lamp if the supply voltage rises. This maintains the average lamp current constant, since the line voltage will be lower earlier in the cycle, leading to less ionization in the lamp and compensating for the increased voltage amplitude. In a similar way, the circuit also compenates for variation in the lamp impedance, e.g. during warming up, since the auxiliary lamp E is connected in series with the main lamps x.

Patent GB-2021483-A (GB)
Title: Stencil duplicator inking control
IPC: B41L39/00
Filed: 1979-04-12
Abstract: A control mechanism for art ink layer on a duplicator cylinder employs a sensing roller 8 mounted for movement along a path which extends both peripherally and radially of the cylinder where the ink is to be measured and thus the drag by the ink pulls the roller 8 to an equilibrium position. The position of roller 8 thus is a measure of the amount of ink present. The pivoting support 9 for the sensing roller may engage a switch 12, 13 when an extreme position is attained and this provides an "enough ink" signal. The sensing roller may additionally be subject to a basing selective manually by the operator and/or responsive to the speed of rotation of the duplicator to control ink layer thickness. The sensing roller can be able to skew so that a switch at one end of the duplicator cylinder may be tripped before one at the other to provide a control responsive to local thickness of the layer. Several different rollers 8 which between them cover the entire axial extent of the cylinder and thus can control the application of ink locally may be provided. <IMAGE>
