Title: Improvements in or relating to apparatus for testing transistors
IPC: G01R31/26
Filed: 1960-06-29
Abstract: 952,623. Testing transistors. WESTERN ELECTRIC CO. Inc. June 29, 1960 [July 17, 1959], No.22711/60. Heading G1U. For measurement of the common emitter amplification factor #0 defined as the ratio of collector current to base current with collector shorted to emitter, of a p-n-p transistor 11 (Fig.2) the base is grounded over a linearly variable resistor 15 of resistance aRp where Rp is the maximum value in series with a fixed resistor 16 of value R 1 , and a signal generator 17 applies a current at e.g. 1 kc/s between the emitter and junction 15, 16 through transformer and capacitance coupling in superimposition on the emitter bias. The collector bias source is decoupled to ground by capacitor 28, and the total signal across 15, 16 is inductance capacitance coupled to tuned amplifier 31 and output meter 32. Resistor 15 is adjustable to produce a zero reading of the output meter, and it is shown that # 0  is proportional to aRP/R 1  so that the resistor may be calibrated in terms of # 0 . In a modification (Fig. 4 not shown) the amplifier and output meter are replaced by a selective servo amplifier and biphase motor adjusting the variable resistor and operating an indicator. The motor is also energized from the signal generator which excites the transistor through an attenuator. Fig. 5 shows a modification for measurement of #o as the ratio of total D.C. collector current to total direct base current with the emitter to collector D.C. resistance small by comparison with the internal col - lector impedance of the transistor. The base is grounded over resistances 15, 16 as above and a forward D.C. bias is applied between the emitter and the junction of 15, 16 over resistor 41. Reverse D.C. bias is also applied between the collector and ground and a D.C. voltmeter is applied across resistors 15, 16. Resistor 15 is adjusted for null reading and as before may be calibrated in terms of and/or automatically adjusted by a servomotor. N-p-n transistors may be similarly tested with reversal of the D.C. bias polarities. The variable resistor may comprise a potentiometer having the slider connected to one end connected to the fixed resistor. Specification 806,795 is referred to.

Title: Improvements in converging-diverging jet propulsion nozzle
Inventor: ALFORD JOSEPH SAVAGE
IPC: F02K1/06
Filed: 1960-06-29
Abstract: 894,450. Jet propulsion nozzles. GENERAL ELECTRIC CO. June 29, 1960, No. 22830/60. Class 110 (3). A convergent-divergent jet propulsion nozzle having a divergent wall defining the divergent section comprises a wall surrounding the divergent wall to form a plenum chamber and circumferentially spaced longitudinally-disposed openings in the divergent wall in communication with the plenum chamber to stabilize the shock-wave. A convergent-divergent nozzle, Fig. 1, comprises a converging section 10, a throat 11 and diverging section 12. A wall 14 defines a plenum chamber with the diverging section 12. During operation of the nozzle at pressure ratios less than the designed value a shock-wave 15 is formed. To stabilize the position of the shock-wave longitudinal slots 16 are provided to connect the areas of varying pressure before and after the shock-wave. Movement of the shock-wave causes variations of the flow through the slot to restore the pressure balance across the shock-wave and so compensate for the factors causing the movement. In practice, cooling air always flows radially inwards through slot 16 and movement of the shock-wave will cause a change in the relative flow through the slots in the vicinity of the shock-wave. In a modification, Fig. 6, the nozzle is of the variable area type formed by fingers 17 pivoted to the end of the tailpipe. Seals 23, 24 span the spaces between the inner and outer surfaces 21, 22 of the fingers. Stabilizing slots 25 are formed by the omission of a portion of selected seals. The slots 25 are exposed only under maximum speed conditions and are covered by the adjacent fingers under conditions of subsonic flight. The slots 16, 25 may be replaced by perforations and the slots 16 may be tapered from one end to the other.

Title: Control systems for electrical motors
IPC: H02P3/24
Filed: 1972-05-16
Abstract: 1390666 Control of A.C. motors ODESSKOE SPETSIALNOE KONSTRUKTORSKOE BJURO SPETSIALNYKH STANKOV 16 May 1972 22835/72 Heading H2J A method of braking an A.C. motor having at least two windings comprises the steps of disconnecting the windings from their normal power supply, short circuiting at least a portion of at least one but not all of the windings and feeding rectified current through at least a portion of the other winding or windings but not through the winding or windings which include(s) a short circuit, whereby to induce a current in the shorted winding or windings, which current acts to oppose rotation of the motor. Embodiments are described wherein a motor having five stator windings is braked by connecting two of them in series through a diode to an A.C. supply and short circuiting the remaining three through a single contact set, Fig. 1 (not shown), or by connecting them one across another through two contact sets. Fig. 2 (not shown). The two groups of windings are inductively coupled through the rotor, which is of squirrel-cage type, so that the current in one group induces a current in the short-circuited group producing a braking torque whose value varies with the motor speed. Typical characteristics, Fig. 3 (not shown), relating the braking moment and motor speed and torque are discussed to explain the coupling action of the winding groups and the forces (14, 15) produced by the A.C. and D.C. components of the rectified current, their resultant force (16) with windings not short circuited, the force (17) produced by short-circuiting and the resultant of forces (16, 17) which provides a braking moment over the whole range of motor speeds. Fig. 4 shows the application of the invention to a single-phase capacitor induction motor having stator windings 19, 20 energized from an A.C. supply through a capacitor 23 and the contact sets 21, 22 of a starting contactor. To brake, the contact sets 21, 22 are opened and the contact sets 24, 25 of a braking contactor are closed. In Fig. 5, a three phase induction motor 26, 27, 28 is driven in one or other direction by closure of starting contact sets 29, 30, 31 or 32, 33, 34 and is braked by opening of the latter contact sets and closure of the contact sets 35, 36, 37 of a braking contactor. A current-limiting resistor may be connected in series with the contact set 35, Fig. 6 (not shown). Contact sets 35, 36 may be'replaced by sets (43, 39) respectively connected in the primary and secondary circuits of a stepdown transformer (41), whose secondary winding (40) supplies the series combination of windings 26, 28 through the diode 7, Fig. 7 (not shown). This diode may be replaced by a controlled rectifier in the embodiment of Fig. 5. Also discussed are the control of a motor with delta-connected windings and the use of fullwave rectified current to increase the braking at high motor speeds.
