Abstract: 373,735. Arc welding systems. ADAMSON, G. R., of Adamson & Co.. J., Hyde, Cheshire. April 20, 1931, No. 11614. [Class 39 (iii).] The armature of the electrode feed motor e is fed from a D.C. generator # having a field winding g in series with the arc and an opposed field winding i in shunt to the arc, the windings being proportioned so as to reverse the polarity of the generator with consequent reversal of the motor at the correct periods. The welding current generator is connected to the leads h, and the electrode and the work to the leads h<1>. The strength of the field i may be varied by a regulator j. A second resistance k in the circuit of the field i is short-circuited by a contact m when the electrode contacts with the work. The operating-coil p of the contact m is in a circuit having a switch o controlled by a coil n in series with the arc. A voltage limiting relay q polarized by a coil r controls a contactor s in the circuit of a coil t controlling a contactor u to short-circuit the field g when the generator voltage is excessive.

Title: Descaling or rough-turning machine
IPC: B23B5/12
Filed: 1967-03-14
Abstract: 1,148,121. Cleaning tubes &c. M. VON BUSHE and T. ALTENBRACHT [trading as TH. KIESERLING & ALBRECHT]. 14 March, 1967 [10 Oct., 1966], No. 11996/67. Heading F2N. [Also in Division B3] In a machine for descaling tubes wherein the tube is secured against rotation and is passed through a rotating cutter head in which the cutting tools are radially adjustable during rotation of the head, means are provided to sense and indicate any deviation from a desired diameter of the machined tube and to automatically adjust the cutters to the required diameter. The tube is fed by rollers 1, 1a through the cutter head 3 whereafter it is gripped and held by clamping jaws 7, 7a the upper jaw 7a being mounted on a slide so as to be adjustable to accommodate different size work. Between the head and the clamping jaws is located a sensing device which continuously measures the diameter of the machined tube. The sensing device comprises upper and lower feeler members 9a and 9 carried in body members 16 and 14 respectively which are adjustable relative to each other by a screw turn-buckle 15. The body members are themselves releasably secured in a frame 17 by screw handles 28, 29, the frame being resiliently carried in a carrier frame 20 by a spring 21. The upper feeler member 9a is connected by a plunger 22a, biased by a spring 23, to an electrical inductive senser 10, as that any movement of the feeler member 9a due to a change in the diameter of the tube causes pulses to be transmitted via an amplifier and a comparator to an instrument 13. The signals received from the sensor are subsequently transmitted to a motor for the operation of a worm 41 connected to a thread sleeve 34 in the cutter head. The rotation of the sleeve 34 and the axial displacement thereof causes the radial displacement of the cutting tools 30 by co-operation of the tool holder 31 with an internal central surface 33 of the sleeve.

Title: Improvements in or relating to electric motor control systems
IPC: B60L7/12
Filed: 1946-04-18
Abstract: 610,989. Control of D.C. motors. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. April 18, 1946, No. 11997. Convention date, April 21, 1945. [Class 38 (iii)] A direct-current motor control system comprises means for establishing dynamic braking connections for the motor, a resistor connectable in series with the motor armature during braking for controlling the motor braking current, means for shunting said resistor step by step, and relay means responsive jointly to the motor current and the voltage drop across a portion only of the resistor for controlling the operation of said resistor-shunting means, whereby the voltage developed by the motor during braking is limited to a permissible maximum value, and, at the same time, the available braking capacity is fully utilised. For forward operation of a motor 10, controllers CS and MC are moved to appropriate positions to close a line switch LS and reversing switches F1 and F2 and connect the motor across supplylines 13 and 16 in series with a resistor R. Further movement of the controller MC energizes the coils of electromagneticallyoperated valves SV and IV to operate an air engine 22 which drives the shaft of a controller CC to progressively remove the resistor R from the motor circuit. When the motor current exceeds a predetermined value, a contact of the relay LR, one section of a series coil 23 of which is in the motor circuit, is opened to de-energize the coil of valve IV and stop the forward movement of the controller CC. When the controller MC is moved to an "off " position, the relays LS and F1 are opened and the controller CC is returned to its first position. A braking controller BC may then be operated to close switches B, E and R1. A braking circuit comprising the resistor R, a resistor 19, the series field winding 11 and both sections of the series relay coil 23 is connected across the motor armature. The field winding 11 is connected across the power-lines through contacts of switches E and F2. A shunt coil 24 of the relay LR is connected across the first two sections R11 and R21 of the resistor R. Provision is made for automatically changing the setting of the relay LR during braking so as to permit the motor voltage to follow closely the maximum permissible voltage without exceeding it. Thus, during the first few steps of braking when the motor speed is high, the coil 24 aids the series coil 23, thereby lowering the setting of the relay LR which so governs the operation of the controller CC as to restrict the motor current to the value set by the relay. This reduced current reduces the motor excitation and prevents excessive motor voltage. When the braking current is so reduced that the controller CC operates to remove the resistor sections R11 and R21, the shunt relay coil 24 is no longer effective and the setting of the relay LR is increased to a normal value suitable for motor operation at moderate speeds.
