Title: Arc length regulator for consumable electrode melting
IPC: H05B7/109
Filed: 1964-05-14
Abstract: 1,059,784. Automatic control systems for arc furnaces. UNIVERSAL-CYCLOPS STEEL CORPORATION. May 14, 1964 [Nov.15, 1963], No.20125/64. Heading G3R. In an arc furnace 2, the arc between a consumable electrode 1 and a pool 3 of molten metal is supplied from a system 9, 8, 6, 7 and is automatically maintained at a desired length by a control system including a motor 12 for driving the electrode 1, a generator 13 supplying the motor 12, an exciter 16 for the generator 13, an exciter field winding 18 associated with a device 19 having a reference coil 20 and a regulating coil 21, a reference capacitor 27 connected to the coil 20, and a regulating capacitor 24 connected to the coil 21. In operation, capacitors 24 and 27 are first charged to the arc voltage; capacitor 27 then discharges into the coil 20 producing a certain flux, whilst capacitor 24 discharges both into the arc over a diode 39, and into the coil 21. The arrangement is such that the motor 12 is inoperative whilst the flux produced by coil 20 is greater than that produced by coil 21, this condition obtaining when the arc is of proper length or less. If the arc becomes too long, relatively more current discharges from capacitor 24 through the regulating coil 21; when the regulating coil flux exceeds the reference coil flux the device 19 connects a supply 22 to the winding 18 which, being energized, in turn causes the generator field to be energized so that the motor runs in a direction to lower the electrode 1. Timing relays ensure that the capacitors 24 and 27 are charged and discharged every few seconds, so the arc length is under constant regulation. The exciter 16 is also provided with a field coil 65 associated with a device 66 which causes the motor to raise the electrode 1 should the arc become abnormally short, a field coil 70 which is constantly energized to provide a small amount of up-drive bias on the generator to counteract the weight of the electrode 1, and a field coil 79 which is associated with a device 75 similar to and connected to the device 19 and which is energized when the arc becomes too short causing the motor 12 to raise the electrode 1 a slight amount.

Patent GB-871839-A (GB)
Title: Improvements in or relating to processes for the production of semiconductive bodies
IPC: C30B15/00
Filed: 1958-06-24
Abstract: A method of producing a semiconductor body of uniform resistivity suitable for use in transistors and rectifiers comprises crystallizing from a melt consisting of the semiconductor as major ingredient and two significant impurity solutes as minor ingredients, the solutes being either of opposite conductivity imparting types and having values of 1-k (k being the distribution coefficient) of the same sign, or of the same conductivity imparting type but having values of 1-k of opposite signs.  The ratio of the concentration in atoms/c.c. of one solute to that of the other is between 0.8 and 1.2 times the absolute value of the ratio of the growth rate coefficient of the distribution coefficient of the other solute to that of said one solute for a desired growth rate.  Typical systems of the first type mentioned above are germanium containing gallium and antimony, indium and arsenic, or indium and antimony, and silicon containing gallium and antimony, arsenic and boron, or phosphorus and boron. Two typical systems of the second type are germanium containing gallium and boron, and indium antimonide containing zinc and cadmium. It is demonstrated mathematically in the Specification that the uncompensated activator concentration in the crystallizing material and hence the resistivity is far less sensitive to changes in growth conditions with time and variations in such conditions over the cross-section of the freezing interface than that of material of the same resistivity crystallized from a melt containing only a single significant impurity solute, particularly when the ratio of concentrations is equal to the aforesaid ratio.  Additional significant impurity solutes or impurities for controlling the carrier lifetime of the material may also be incorporated in the melt.  The crystallizing process may be a normal freezing operation such as crystal pulling, or a zone melting process.  Compensation for changing concentration in the melt may be effected by gradually changing the growth rate as the process proceeds.  Specifications 727,678 and 769,673 are referred to.

A device for testing axis and wheel alignment and inclination of motor vehicles comprises a carrier C having two telescopically sliding tubes, a sighting mechanism S with mirrors 13, 15 between which is a sighting needle 14, and a centering mechanism G having two guide rods 16, 17 mounted on which are feelers in the form of centering bolts 22, 23. The point of intersection P, Figs. 10, 11 (not shown) of the vehicle and sighting axes is marked by the marking cone 26 of a marking device M. To check the rear axle alignment the carrier device C is connected to the front axle, and by sighting the marking cone in coincidence with the needle point 14, the position P is found. The apparatus is then connected to the rear axle and the tip of the marking cone sighted through the mirror 15, the rear axle being adjusted until the tip of the marking cone coincides again with the needle point. The forward axis position can be checked similarly. To determine the inclination of the plane of the wheels, the carrier device is equipped with measuring heads H in place of the centering bolts 22, 23. Each measuring head comprises three feelers 31, 32, 33 which assume different axial positions depending on the inclination of a measuring disc 30 clamped to the wheel rim. The position of the feeler 31 relative to feeler 32 gives a measure a of the 'camber' and the position of feeler 33 relative to feeler 32, a measure 'b' of the 'toe out'. The measurements may be recorded by means of a differential transformer or potentiometer. The position of feeler 32 is fixed by means of an impact member 43. In a further embodiment, Fig. 17 (not shown) the measuring heads are fixed and hence alignment of vehicle and sighting axes is dispensed with.
