Filed: 1966-02-11
Abstract: 1,126,523. Measuring D.C. power. ENGLISH ELECTRIC CO. Ltd. May 10, 1967 [Feb. 11, 1966], No.6236/66. Heading G1U. In a system for measuring the power flow through H.V.D.C. lines 1,2, a transductor 8 monitors the current in the line 1 and a direct current proportional to the transductor output is fed to the fixed coils 12, 13 of a dynamometer, the moving coils 3, 4 of which are supplied by a signal proportional to line voltage, so that the dynamometer torque represents power flow in the lines. The output of a position sensing coil 16 is fed to a phase detector 20 whose D.C. output is passed through an amplifier 21 to a torque balancing coil 17 moving in the field of a permanent magnet 18, so that the magnitude and polarity of the D.C. current in the coil 17 represent the power flow and its direction in the lines. Protective circuits 6, 7 comprising valves, Zener diodes or spark gaps, are connected across resistors R2, R4, across which the line voltage dependent signal is produced, to limit the voltage across the moving coils 3, 4 in the event of an open circuit in the latter. When a neutral return is included or unbalanced operating conditions are expected a transductor is included in each line 1,2 and each transductor supplies one of the dynamometer coils 12, 13. The D.C. in the balancing coil 17 can be converted into a train of pulses feeding a stepping motor so that the D.C. is integrated to give the energy flow along the lines. Two motors can be used, one responsive to each polarity of direct current in the balancing winding 17, to measure energy flow in both directions along the lines 1, 2. To compensate for losses in the cables an auxiliary transformer is used, having its primary in series with the transductor 8 and its secondary connected through an auxiliary bridge rectifier to the moving coils 3, 4.

In a rotary cutter head having an annular body portion 20 in which are radially located a plurality of carrier members 24 for steady rollers and at least one cutting tool 27, means is provided for releasably clamping the carriers in the body. In one embodiment the clamping means for each carrier is constituted by a rotatable spindle member 41, located in the body and extending parallel to the axis of the cutter head and which co-operates with a recess 39 in the carrier. The spindle 41 is provided with a recess 42 having a depth equal to the radius of the spindle and extending axially along the spindle whereby rotation of the spindle to a position where the recess clears the carrier permits the carrier to be removed from the body. Similarly, after insertion of the carrier in the body, rotation of the spindle to engage the solid portion thereof in the recess 39 effects clamping of the carrier in the body 20. To ensure that the cutter head cannot be put into operation without the carriers being securely clamped in position electrical switch means may be incorporated to indicate when clamping has not been effected (Figs. 6 and 7, not shown). The carriers for both steady rollers and the cutting tool(s) are provided with screw adjustment means to facilitate the correct positioning of the tool(s) and rollers prior to operation.

Title: Improvements in means for the control of spot-welding
IPC: B23K11/31
Filed: 1939-02-27
Abstract: 525,707. Welding. AUSTIN MOTOR CO., Ltd., and MILES, W. L. Feb. 27, 1939, No. 6376. [Class 83 (iv)] A spot welding apparatus operated by a double-acting compressed-air piston is controlled by a hand-operated piston valve controlling parts so that in its normal position the piston of the movable electrode is held in its raised position, in an intermediate position air is supplied to the upper end of the electrode piston and exhausted from the lower end so as to force the electrodes into contact with the work and in the final position pressure is admitted to the cylinder of a fluid-operated switch to put in the welding current. Readjustment of the electrodes on the work may thus be made before the current is put on. The valve is provided with two pistons M, N and is normally pressed forward by a spring O. The space between the pistons M, N is continuously open to pressure from the supply through passage R. In the position shown in Fig. 2, the supply is connected to the lower end of the electrode piston through port T and pipe t, and the port U connected to the upper end of the electrode piston and the passage S communicating with the switch cylinder are, open to exhaust through port Q. On pushing the valve to its intermediate position by a hand lever g<SP>1</SP>, the piston M moves to the other side.of the-port T, which is thus connected to exhaust at P and the piston N moves to the other side of the port U so that the electrode E is forced down. At this time the passage S is closed by the piston N. When the valve reaches its final position the piston N clears the passage S so that the welding switch is operated. On releasing the lever g<SP>1</SP> the pressure on the upper end of the electrode and in the switch cylinder are not connected with the exhaust until the valve reaches its initial position.
