Title: An overload protection device for power transistors of push-pull class b amplifiers
IPC: H03F1/52
Filed: 1962-06-08
Abstract: 1,007,171. Transistor amplifying circuits. TELEFUNKEN PATENTVERWERTUNGSGESELLSCHAFT m.b.H. June 8, 1962 [June 9, 1961], No. 22262/62. Heading H3T. In a Class-B push-pull transistor amplifier, overload protection is provided by the connection in the current supply path of each amplifying transistor of the collector-emitter path of a further transistor, a voltage derived from that developed across the output load being applied to the base electrode of the further transistor so that the current flowing through said transistor is limited in dependence upon the voltage developed across the load to a value which will not cause excessive power dissipation in the amplifying transistors. The voltage developed across an additional winding W of output transformer U2 is applied through diodes D1, D2 to the bases of transistors T3, T3<SP>1</SP> whose collector-emitter paths are arranged in series in the emitter circuits of amplifying transistors T1, T2. If the output load R L  has a large value so that a substantial output voltage is developed, the transistors T3, T3<SP>1</SP> are biased into saturation and the currents through the amplifying transistors T1, T2 are not limited by the transistors T3, T3<SP>1</SP>. If however load R L  falls to a low value, e.g. a short-circuit develops, no output is produced across winding W, so that the base bias of transistors T3, T3<SP>1</SP> is reduced so limiting the currents which can flow through transistors T1, T2. In a modified circuit, Fig. 5 (not shown) a single protective transistor is connected in series between the positive supply terminal and the junction point of the primary windings of the transformer U2. The output transformer U2 may alternatively be connected in the collector circuits of the transistors T1, T2.

Abstract: 1408379 Shot peening SANDVIK AB KRAFTWERK UNION AG and MANNESMANN ROHREN-WERKE AG 20 May 1974 [30 May 1973] 22472/74 Heading B3D A method of shot peening the external surface of a tube 10 that is partly straight 20, 22 and partly curved 21, such as a U-shaped tube for a heat exchanger, using a set 15 of shot peening nozzle 16 arranged around and directed towards the tube, comprises, for shot peening a straight portion of the tube, holding the nozzle set stationary and moving the tube in a straight path with the straight portion passing axially through the nozzle set, and, for shot peening a curved portion of the tube, holding the tube stationary and moving the nozzle set along the curved portion. In a device for carrying out the method, the tube 10 is supported by rollers 11 and gripped by an arm 12 on a sledge 13 movable along a guide 14. The nozzle set 15 has a number of shot peening nozzles 16 spaced around a central area and carried by a bracket 17 movable about a vertical axis. In use, the sledge 13 is moved along the guide 14 so that the straight portion 20 passes axially of the nozzle set which effects peening by blowing glass beads against the surface of the tube to introduce compressive stresses in the surface. When the tube reaches the position shown dotted, the sledge 13 is stopped, the arm 12 is lowered, and the bracket 17 is swung about axis 18 to shot peen the curved portion 21 of the tube. When the nozzle set reaches the position 15a, the sledge is moved to its original position so that the straight portion 22 is shot peened. The set of nozzles is adjustable along bracket 17 to the radius of curvature of the moved portion 21. The sledge device may be placed above the tube. In order to distribute the shot peening effected by the nozzles, alternate nozzles are inclined at a small angle in opposite directions from a plane containing the nozzle set.

Title: Improvements in and relating to installations for the propulsion of watercraft
IPC: B63H21/16
Filed: 1938-07-28
Abstract: 517,449. Elastic-fluid turbines. AKT.-GES. BROWN, BOVERI, & CIE. July 28, 1938, No. 22493. Convention date, Aug. 24, 1937. [Class 110 (iii)] [Also in Groups XXIX and XXXIII] A gas turbine installation, comprising a constant pressure gas turbine 4 coupled directly or through toothed gearing to an air compressor 1, is suitably arranged to drive an adjustable pitch' watercraft propeller 7 through intermediate, gearing 6. The turbine is controlled by a governor 16 actuating, by means of a a leak-off 18, the regulator 12 controlling the servomotor which adjusts the angle of incidence of the propeller blades. A device 32, allowing adjustment of the leak-off 18, enables the speed of the turbine to be predetermined. If the speed of the turbine is greater, than that set for, the governor 16 closes the leak-off 18 and causes the piston 21 to rise. This allows oil under pressure to pass through the regulator 12 to the servomotor which increases the angle of incidence of the blades to slow down the turbine. This, in turn, causes the governor 16 to re-open the leak-off and the piston 21 to return to its original position. In normal operation, the governor 16 also controls a leak-off 25 which regulates a fuel nozzle 3, so that the ratio of air to fuel is kept constant. A device 13 allows the blades to be adjusted for reversing. During reversing, the torque required to drive the propeller drops to a minimum and to prevent racing a spring-loaded valve 29 is provided. As the turbine tends to race, the governor 16 closes the leak-offs 18, 25 and this causes the oil pressure in the lines 19, 26 to equal that in the line 10. The spring-loaded valve 29 then opens to balance the oil pressure on both sides of the operating piston of the fuel nozzle 3 which is shut by the spring shown. A thermostat, responsive to the initial gas temperature of the turbine, may be used to influence the propeller adjusting device so as to control the compressor speed and thereby control the air supply to the combustion chamber. For starting purposes, a motor and over-running clutch or a cruising diesel engine connected through a resilient clutch to the gearing 6 may be used. The Specification as open to inspection under Sect. 91 comprises also the use of the turbine plant as a propulsion means for aircraft. This subject-matter does not appear in the Specification as accepted.
