Abstract: 1,268,844. Heat-treating nickel alloys. UNITED AIRCRAFT CORP. July 8, 1969 [July 19, 1968], No.34406/69. Heading C7A. Nickel-base super alloys are heat-treated to form a homogeneous distribution of precipitated γ<SP>1</SP> phase, the latter having an interparticle spacing not exceeding 5 microns and forming a volume fraction of not less than 25%; they are then worked at a temperature not exceeding the solvus temperature of the γ<SP>1</SP> phase or the gross recrystallization temperature, but not less than the minimum recovery temperature to effect a reduction in area of at least 15% without impairing the volume fraction or distribution of the γ<SP>1</SP>. The alloy is then further heat-treated to stabilise it and provide additional precipitation strengthening. The first step may consist of solution treatment followed by ageing at a temperature between the γ<SP>1</SP> solvus and the minimum recovery temperature. Working may be carried out near the minimum recovery temperature, when a random dislocation distribution is obtained, or near the solvus temperature, when the dislocations are aligned regularly along the polygonal sub-cell boundaries.

Title: Device for rapid switching of inductors

Filed: 1972-07-24
Abstract: 1403222 Transistor switching circuits CARL ZEISS JENA VEB 24 July 1972 34493/72 Heading H3T In a device for rapid switching of inductors, an inductor 1 is connected by means of a main switching transistor 2 to a source of voltage Ub 1 , an auxiliary transistor 5 being connected in series with the inductor 1, auxiliary transistor 5 connecting the inductor 1 during the switching- on period to an auxiliary source of voltage Ub 2  higher than that of the first source for causing the current in the inductor to rise steeply during the switching-on period, the auxiliary transistor 5 being controlled by a circuit comprising a control transistor 28 and a R-C network 25, 26 the operating time of which is so adjusted that the auxiliary source of voltage Ub 2  is disconnected when a desired value of current has been reached. A positive pulse applied via diode 4 and resistor 4 to the base of transistor 27 renders the latter conductive, whereby transistor 29 is biased non-conductive and so biases transistor 2 conductive. The pulse at the collector of transistor 27 is differentiated by differentiating circuit 25, 26 so that the leading edge of the pulse biases transistor 28 non-conductive for a short period: during this period transistor 5 is biased conductive so that inductor 1 is energized from source Ub 2 , but at the end of it energization is from the lower voltage Ub 1  alone.

Abstract: 770,068. Rectifying. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 1, 1954 [Dec. 4. 1953], No.. 34813/54. Class 38 (2). [Also in Group. XL (c)] A load is connected in series with the emittercollector path of a junction transistor and an A.C. supply, a biasing potential being arranged in series with an A.C. derived from the supply in the emitter base circuit so that the transistor is conductive over a part of a cycle. A load 1, Fig. 1, such as a motor or relay is arranged in series with a junction transistor 4 and the secondary 2 of a transformer fed from a supply. A tertiary winding produces an A.C. which overcomes the bias 5 at an adjustable point in the cycle determined by the variable bias and A.C., Fig. 2 (not shown). The impedance of the load 1 and the operative voltages are chosen to keep the power dissipated in the transistor, when conducting, below the maximum permissible. An inductor 8 ensures that the collector voltage is low whilst the transistor is on and it may be arranged to resonate with the smoothing capacitor 7 at the supply frequency. A single secondary winding may be used, Fig. 3 (not shown) tapped if necessary and in a further modification, Fig. 4, the bias potential is obtained by base rectification across resistor 10 and decoupling capacitor 9 and is adjusted by varying the resistor. The resistor may be returned to the emitter, Fig. 5 (not shown). Full-wave rectification may be obtained by employing a NPN transistor, Fig. 6 (not shown), in the circuit of Fig. 4 with the emitter and collector connected to those of the PNP transistor. Alternatively, Fig. 7 (not shown), two circuits employing' PNP transistor may be energized.in push pull.
