Abstract: 1358287 Transistor circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 20 Oct 1971 [23 Oct 1970] 48783/71 Heading H3T [Also in Division H1] In an integrated circuit having means for detecting saturation in a first transistor T 1 , the base-collector path of this transistor is shunted by the emitter-base path of a second, opposite conductivity type, transistor T 2  and during saturation of T 1  charges collected by the collector of T 2  are supplied to the base-emitter path of a third transistor T 3  which is in a branch parallel to the base-emitter path of T 1 . As described with reference to Figs. 2, 2a (not shown) T 1  is a transversal and T 2  a lateral transistor. In the embodiment of Fig. 1, T 1  is an amplifier stage and if its collector-base junction becomes forward biased, transistors T 2 , T 3  switch on so that T 3  shunts a portion of the input signal to limit the saturation of T 1 . In a second embodiment, Fig. 3, transistors T 1 , T<SP>1</SP> 1  form a bi-stable circuit. If T<SP>1</SP> is in its saturated condition, T 2  is conductive and hold the base of transistor T<SP>1</SP> 4  at a higher potential than that at the base of T 4 , thus ensuring that the next trigger pulse at V i  turns on T<SP>1</SP> 4  rather than T 4  to change the state of the circuit.

Abstract: 1371114 Automatic control of beam current STEIGERWALD STRAHLTECHNIK GmbH 27 Oct 1972 [28 Oct 1971] 49628/72 Heading G3R Charged beam apparatus is operated in a pulsed mode, and signals are derived representing the peak current in each pulse. The signals are stored and converted into an analogue signal which is used for regulating the beam current. As shown in Fig. 1, a movable workpiece 12 is thermally treated by the beam 2 from an electron beam generator 1 including a thermionic emission cathode 4, a Wehnelt control electrode 5, an anode 6 and a diaphragm 7. The apparatus is driven by pulses from an impulse generator 17 applied through a control device 14. A ring coil 8 produces a signal proportional to the instantaneous value of beam current, the first part of which is indicative of the peak value of the pulse profile, Fig.2 (not shown). This signal is stored in a circuit 16 until the next pulse is received from generator 17, at which time it is compared with a reference voltage provided by a potentiometer 19 to form an analogue signal which is fed to the control electrode 5 to regulate the beam current. In another arrangement, Fig.3 (not shown), the output signal from the coil 8 is compared with the reference voltage before gating and storage by the circuit 16.
