Title: Improvements in regulating arrangements for dynamos
IPC: H02P9/24
Filed: 1922-03-21
Abstract: 177,522. Jullin, A. J. March 26, 1921, [Convention date]. Dynamos, regulat - ing; exciting.-A variable - speed, variableload auxiliary - brush dynamo, such as a vehicle-lighting machine, is regulated by a. device which is subject to the voltage of the main brushes and reverses current in a shunt field winding so as to enable the machine to act as a limited-voltage generator as well as a limited-current machine bv the known method of regulation by armature reaction. In the form shown in Fig. 1 a vibrating regulator 4 is used with shunt excitation at 8 across the machine 1. The machine is excited by a shunt coil 2, tapped from the auxiliary brush C, and a regulating winding 3. The vibrator is normally spring- pulled on to the contact 5 and the coils 2, 3 assist magnetically, the machine acting as a limited-current generator with internal regulation. From starting up to a predetermined brush voltage, the contact 5 is closed but beyond this voltage the regulator begins to vibrate and ultimately closes on to the contact 6, thereby reversing the current in the coil 3 and limiting the brush volts of the machine. By means of a series coil 10, the machine may be compounded positively or negatively so that the volts may have any desired relation to the load current. The regulator may be of the type described in Specification 143,541 and resistances and condensers may be used to reduce sparking at the contacts. The vibrating regulator may be replaced by any other device which would reverse the current in the windings 3, such asresistances 13, 14, Fig. 2, having positive and negative temperature-resistance coefficients as described in Specifications 101,887, 101,888 and 101,889. The Specification as open to inspection under Sect. 91 (3) (a), comprises also the application of the invention to a machine of the Rosenberg type, as shown in Fig. 3, (cancelled). In this case, the regulating coil 3 is connected between the diametral short-circuited brushes c, c<1> and a moving arm which reverses the current in the regulating coil, 15 is a series compensating coil arranged to limit the output of the machine and 16 and 17 are resistances. The coil 15 may alternatively carry only the load current instead of the load and exciting currents. This subjectmatter does not appear in the Specification as accepted.

Patent GB-983454-A (GB)
Title: A method of surface hardening steel rolls and apparatus for carrying out the same
IPC: C21D9/38
Filed: 1962-03-02
Abstract: In the surface hardening of steel rolls, the depth of hardened zone is increased by using a high electrical power density for heating, which may be either conductive or inductive, while simultaneously cooling the surface.  Cooling is then discontinued and the temperature of the treated zone allowed to equalize to a temperature above the critical, aided if necessary by supplementary heating, after which the roll is quenched.  The whole surface may be treated at one time, or treatment may be progressive. Pior to hardening the surface region may be preheated to about 750  DEG C. using a low power density and no cooling.  As shown in Fig. 1, roll 1 is moved axially through inductive heating coil 3, coolant being supplied between the turns of the coil at 4. Temperature equalization occurs at 6, and the roll then passes through annular quenching spray 7.  In the embodiment of Fig. 2, the roll is simultaneously rotated and advanced axially, heating being carried out by inductor loops 9 between which the located coolant sprays 11.  Fig. 5 illustrates a modification using conductive heating, the contact rollers or slippers being placed at location 7 or 3 depending on whether or not the hardened zone is to extend to the edge of the cylindrical part of the roll body.

Filed: 1942-06-18
Abstract: 558,814. Control systems for resistance welding &c. BRITISH THOMSON-HOUSTON CO., Ltd. June 18, 1942, No. 8353. Convention date, June 19, 1941. [Class 38 (iv)] Thermionic control.-An impulse of current is obtained from an inductance, such as the primary winding of a transformer feeding a welding circuit, by interrupting unidirectional current flowing in the inductance when the current in an A.C. supply circuit furnishing it has reached a predetermined value. A valve 34 is maintained non- conductive by a grid bias voltage derived from a potentiometer 42 in shunt with a voltage stabilizing glow discharge tube 40 supplied from a D.C. source comprising a condenser 30. When a switch 51 is opened a coil 32, energized across a resistance 39 in series with the tube 40, is deenergized and a relay 19 operates to connect the inductance 17 to a polyphase rectifier circuit 3. As the current rises in the inductance a current transformer 45 superposes an alternating voltage on the grid of valve 34 which, accordingly, becomes conducting at a current value predetermined by the potentiometer tap and energizes the coil 32 to cause the relay 19 to interrupt the current through the inductance. The rectifiers may have immersion-ignitor control members and the voltage of the D.C. furnished may be determined by controlling or adjusting the timing of the impulses supplied by the exciting circuit 15 to these members.

Abstract: 880,299. Testing gyroscopes. STANDARD TELEPHONES & CABLES Ltd. March 13, 1959 [March 15, 1958], No. 8806/59. Class 40 (1). [Also in Group XX] Axial mass unbalance in a gyroscope is indicated by imparting a linear vibration to the gyroscope and detecting any cyclic precession caused thereby. A gyroscope 1 is mounted in the usual way and caused to vibrate vertically by means of a spring-mounted table oscillated by an unbalanced wheel 17 driven by a motor 15. Any unbalance of the rotor 3 will produce a cyclic precession about the axis 8 and generate a corresponding cyclically varying signal from a D.C. energized potentiometer 19. An oscillator 25 is synchronized with the driving motor 15 so that the modulation of the potentiometer output is of the same frequency as the oscillator and of a phase relationship depending on the position of the rotor unbalance. The two signals are fed into a ring demodulator 24 to give a D.C. output whose amplitude and polarity indicate the magnitude and direction of the rotor unbalance. This output is shown on a centre-zero meter 49. When the gyroscope is used in an inertial navigation system the balanced modulator can be omitted and the potentiometer signal fed into a computer which supplies a correcting signal to create an equal and opposite precessional torque. The potentiometer 19 can be replaced by a synchro.
