Abstract: 1453489 Heating metal workpieces ELECTRICITY COUNCIL 9 June 1975 [7 March 1974] 10336/74 Heading B3M [Also in Division H5] Slabs, billets, or other metal workpieces moving along a path are heated by controlled switching of one or more induction heaters located along the path, so that the heat input to the workpiece varies along its length in a predetermined non-uniform manner. The figure shows reheating of a strip 11 passing from a reheating furnace to a roughing mill, or between roughing and finishing stages, on a roller table 11. Induction heaters 12 are located between the rollers 10, and are cyclically switched on and off in sequence in accordance with the location and the known or measured speed of the strip so as to compensate for sinusoidal temperature distribution along the strip caused by the supports on which the strip rests in the furnace. The heat input may also compensate for a temperature gradient along the strip. Additional inductors or lamination packs may be located above or below the strip path to modify the flux path and hence the distribution of heating. The switching may be effected by a mechanical commutator or by solid state switches. The inductors may employ U-shaped cores having a single slot between two upstanding teeth, each coil being wound with a turn extending along a slot in one core and back along a slot in an adjacent core, or E-shaped cores, each coil being wound around a central tooth. Fig. 3 shows a laminated core 13 with slots 14 in which inductors 15 are wound.

Title: Improvements in and connected with Electric Motor Starting Switches or Controllers.
IPC: H02P1/02
Filed: 1916-08-02
Abstract: 105,181. Newton, F., and Newton Bros. Aug. 2, 1916. Controllers, actuating-mechanism for; checking- devices actuated by the motor current; with novolt and overload releases.-The first operation of a controller closes the motor circuit and also stores energy in a spring for the further actuation of the controller, which is held fast until the motor current drops to a predetermined value. The electro-magnet used to hold the controller in its first position also constitutes the automatic release magnet. The controller is enclosed in a watertight casing, and the leads are taken in through the gland f. The starting-resistance is wound on enamelled iron supports h. The controller fingers are operated by a spindle upon which is loosely carried an armature 3 connected to the handle by a lost-motion connexion to render a quick break possible, and connected by a spring 5 to an arm 6 fixed on the spindle. A second armature 11 is loosely mounted on the spindle, and the armatures 3. 11 co-operate with the pole-pieces 7, 10 of the electro-magnet 9. A spring 12 pulls the armature 11 towards the electro-magnet, and a spring 14 connects the arms 6 to the casing. The disk of the arm 6 has a stop 15 to engage the armature 3, and stops 16, 17 to engage the armature 11. In the off position, the armature 3 and arm 6 are pulled by the spring 14 away from the electro. magnet 9, and the armature 11 is pulled by the spring 12 to the pole-piece 10. When the spindle is rotated in an anti-clockwise direction, the motor circuit is closed through resistance, and the armature 3 is moved mechanically to the pole-piece 7 and is held there by the electro-magnet 9, which carries the motor current and also holds the armature 11. During this movement, the spring 14 is stretched until the stop 16 engages the armature 11, and after this engagement the spring 5 is stretched. As the starting-current decreases, the armature 11 is released, and the spring 5 acting through the stop 16 snaps off the armature 11 and moves the arm 6 to throw the controller into its second position, thus cutting out resistance. When the electro-magnet 9 is de-energized, the spring 14 moves the arm 6 and armature 3 to the off position, and the spring 12 returns the armature 11 to the pole-piece 10. The spindle may be operated by an electro-magnet for remote control, and an armature may be provided to shunt the flux in the armature 3 and so act as an overload release. The number of controller steps may be increased by providing additional sets of mechanism, the parts being interlocked to ensure a correct sequence of steps.

Title: Improvements in or relating to method and apparatus for plotting equipotential linesand surfaces
IPC: G01R29/24
Filed: 1941-08-28
Abstract: 555,196. Voltage measurements. JARRARD, W. J., MORITZ, M. R., and ZADE, H. P. Aug. 28, 1941, No. 11011. [Class 37] In order to plot equipotential lines and surfaces between systems of electrically charged conductors a model is made in which cross-sections of different dielectrics of any specific inductive capacities, forms, or sizes are represented by cutting to scale blocks or films of jellied electrolytes, the conductivities being in the proportions of the specific inductive capacities. 2 to 3 per cent of agar-agar or gelatine gels may be dispersed in water and potassium chloride solution dispersed throughout the medium in sufficient concentration to give the desired conductivity. The jelly is then carved or cast into the required shapes. Alternatively, sheets of blotting paper are dipped into the warm solution and allowed to drain and cool so that the jelly is formed in the interstices. The paper is then cut to the forms desired. Two metal electrodes 13, 14 are stood on edge on the sheet of paper 12 and are connected to the ends of a potentiometer 17 supplied with audio-frequency current from a buzzer or other source 18. An exploring needle or probe 19 is connected through ear-phones 20 to the slider of the potentiometer. The needle is adjusted until minimum sound is produced and is then pricked through the paper to a sheet of squared paper beneath. By plotting a series of such points an equipotential line is obtained corresponding to the potential of the probe. Other equipotential lines are obtained by altering the position of the slider of the potentiometer. Alternatively the probe may form part of a pantograph. A third electrode 21 may be connected to the slider of a potentiometer 22. The invention is applicable for determining the strength and direction of the electric field in connection with the welding of thermoplastic materials by high-frequency A.C fields as described in Specification 555,054, [Group XI].
