Title: Improvements in means for providing protection against overheating of electric motors when stalled
IPC: H02H7/085
Filed: 1953-03-05
Abstract: 728,862. Control of motors. LAURENCE, SCOTT & ELECTROMOTORS, Ltd., and WHEELER, H. D. Feb. 12, 1954 [March 5, 1953], No. 6116/53. Class 38 (3). Means for. protecting an electric motor against over-heating when stalled comprise auxiliary resistors 3, 4, connected across the whole or a part of the main controlling resistance 2, the operating-coil 7 of a protective relay 5 being connected across the resistor 3. The auxiliary resistors 3 and 4 have respectively high and low resistance-temperature coefficients and the cold resistance of the element 3 is considerably lower than that of the resistance 4. When the motor is stalled, an approximately constant voltage is applied across the series circuit comprising the two resistors 3, 4, and, as the resistor 3 becomes heated, the. voltage across it increases until the relay 5 is actuated to interrupt the motor circuit or to include more main resistance in series with the motor. In a modification, Fig. 2 (not shown), two auxiliary resistance units are employed, each unit comprising two series-connected resistors 3, 4. The two units are connected in parallel across a part or the whole of the main controlling resistance with the coil of the protective relay bridging the two units. In another arrangement, Fig. 3 (not shown), the protective relay is differentially wound with one winding connected across the resistor 3 and the other winding of the relay connected between resistors 2 and 3. Alternatively, the differential winding of the protective relay may be connected across the respective series-connected auxiliary resistances, Fig. 4 (not shown).

Filed: 1978-02-16
Abstract: This circuit arrangement has first and second attenuators (T0, T1) in the transmitting channel and in the receiving channel downstream of the pre-amplifiers (V1) or upstream of the power amplifier stages (V3). Thanks to additional attenuation-reducing components (R'3, R5), the channels never appear to be dead and dialogue is facilitated. With a self-regulating circuit (R6, R7, T'2), amplitude is limited at the output of the power amplifier stage (V3) with the result that impermissible or function-impairing amplitude values are avoided. <IMAGE>

Title: Improvements in or relating to the control of electric spot welders
IPC: B23K11/24
Filed: 1942-05-11
Abstract: 550,615. Control systems for resistance welding. BATEMAN, J. R. May 11, 1942, No. 6320. [Class 38 (iv)] Switching control ; thermioniccontrol.-The duration of current in a spot weld is controlled by the discharge of a condenser to a critical value which depends upon the welding current. The duration is also adjustable by a resistance in the discharging circuit. The condenser 16 is charged from a potentiometer 26 when not welding. A control relay 14, energized by a control transformer 12 responsive to the value of welding current, establishes a discharging circuit through adjustable resistance 28 when the pedal switch 1 is closed to operate contactor 4 and energize the welding transformer 8. The condenser biases negatively the grid of a control valve 20 in series with the control transformer 12 and a secondary relay 22, which therefore operates when the critical voltage of the condenser is reached. This instant will depend upon the condenser discharge rate, determined by resistance 28, an the anode voltage of the valve, which depends upon the welding current. The welding time increases at a greater rate than a decrease in welding current, and vice versa, due to the valve characteristics. The secondary relay 22 opens the contactor circuit and closes a maintaining circuit for itself through the pedal switch which must be opened and reclosed for the next weld.

Abstract: 754,431. Making pipe headers; stamping. HUET, A. March 12, 1952 [March 12, 1951; May 17, 1951], No. 6430/52. Classes 83 (2) and 83 (4). A relatively large diameter header a is formed with a flanged aperture for the connection of a tube b of relatively small diameter by heating the header to white heat where the aperture is to be formed and then pushing out the heated portion by means of a punch c operating within the header. The punch is mounted on a double-acting piston d operating within a cylinder d<SP>1</SP> shaped to conform to the interior of the header. An apertured die e held against the outside of the tube co-operates with the punch to form a relatively long connection nozzle f of gradually decreasing thickness towards the end to which the tube b is to be secured as by welding at h. The punch c may be moved sufficiently to pierce the header or may merely form a projection with a closed end which is subsequently cut-off. Water-cooling passages v may be formed in the punch and in order to prevent excessive cooling of the header wall, the head of the punch is in the form of a cone t of apex angle 120 degrees, which contacts only a part of the wall, below which is a truncated conical portion which may have grooves u<SP>1</SP> and u<SP>2</SP> for a heat insulating and lubricating material such as glass wool. A machine for forming a number of connection nozzles along a header a comprises a base j, Fig. 5, with a fixed frame or arch m and along which may be traversed by a screw k a cradle i supporting the header. On the frame m is mounted the die e which may be pressed on to the header by hydraulically actuated toggle links and a blowpipe u whose flame passes through a second aperture in the die to heat during one punching operation the area of the header next to be operated upon. The cylinder d of the punch piston has connections to a pressure fluid supply and the punch is coupled to a supply of cooling liquid.
