Title: Device for ruling lists, schedules and the like
IPC: B43L13/02

Patent GB-615406-A (GB)
Title: Improvements in and relating to electric motor control systems
IPC: H02P7/34
Filed: 1943-10-18
Abstract: 615,406. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 18, 1943, No. 17063. Convention date, Oct. 19, 1942. [Class 38 (iii)] Varying electromotive force.-The exciter for the generator of a Ward-Leonard control system has two opposed control windings, one energized by the generator volts and the other receiving reversible energization from a separate source and determining the polarity of the generator and, consequently the direction of rotation of the motor to be controlled. Excessive pump-back current during reversing of the motor is avoided by de-energizing the first control winding until the polarity of the generator has reversed, whilst a further control winding, opposing the first, may be brought into action to reduce the nett energization of the exciter when the current transmitted between the generator and motor reaches a predetermined maximum value. As shown, the exciter 16 is of the armature reaction excited type and has control windings 16c, 16d, 16e, as well as a winding 16b which compensates armature reaction on the load axis. Winding 16c is energized from supply 11 over directional contactors 17, 18 and determines the sense of the excitation supplied by the exciter to the field 14b of the generator, whilst the opposing winding 16d-in series with an adjustable resistance 23 for controlling the generator voltsis energized by the voltage drop across the portion 20a of a potentiometer 20a, 20b connected across the generator, one or other of oppositely poled rectifiers 29, 29<1>. being connected in series with winding 16d by relays 30, 31 under the control of the directional contactors. Thus, assuming the plant running and controller 19 set in the " forward " direction F, contactor 17 is energized and its then closed contacts 17c have energized relay 30 which is then self-maintaining over contacts 30b and interlock 18e. Rectifier 29 is thus connected in series with winding 16d and is poled in such a direction as to allow exciting current to pass through the winding. If controller 19 is now moved to the " reverse " position R, contactor 17 drops out and 18 picks up, thereby reversing the energization of winding 16c, breaking the maintaining circuit of relay 30 at contacts 18e and energizing relay 31. Rectifier 29 is thereby substituted for 29, but as the former is oppositely poled, current through winding 16d ceases until the generator voltage has reversed..Winding 16e, which is normally unenergized, provides an excitation component opposing that of 16c when the voltage drop across the generator and motor series fields 14a, 10b exceeds that across biassed rectifiers 24d, 24e. The nett excitation is thus reduced and the current in the generator-motor armature loop limited.

Title: Insulating coating for electrical conductors
Inventor: EARL JOHN ALFRED
IPC: H01B3/08
Filed: 1964-04-24
Abstract: An insulating vitreous coating material comprises in per cent by weight PbO, 70-82; SiO2, 10-14; Bi2O3, 6-14; it contains no B2O3. Also present may be:  up to 2% of Al2O3; up to 2% in total of oxides of Ce, Zr, Ti and Mo; and up to 6% of any of BaO, La2O3, MgO, CaO, ZnO, SrO and BeO.  The balance, if any, consists of other compatible constituents.  The mixture, which may comprise, e.g. lead mono-, bi- or tri-silicate, white lead, red lead or bismuth subuirate, is smelted at, e.g. 1150 DEG  C., quenched in water and ground to pass 400-mesh (American Standard), yielding a slip for applying to wire, e.g. of Al or magnetic carbon steel.  After application, firing is performed at, e.g. 540-650 DEG  C.  If the wire is of Al, then the coating adheres to a tenacious film of Al2O3.  The coating may have a nodular form which enhances the adhesion of the coating despite flexure of the wire. The coating has a low thermo-neutron capture and accordingly does not deteriorate excessively in a nuclear reactor.

A gyro-magnetic resonance induction head, for use in a spectrometer or magnetometer, comprises a metal tube 10 within which are disposed a transmitter coil 13 and a receiver coil 14, the coils being spaced apart along the axis of the tube 10 with their axes transverse thereto and mutually perpendicular and slots 16 and holes 18, 20 electromagnetically couple the coils to a sample receiving space 15. A polarizing magnetic field, or the field to be measured, is applied in the direction of the axis of the tube 10. The coupling between the coils and sample is adjustable by moving a loop of copper wire foil 26 and a sheet of gold 27 axially and circumferentially of the tube 10. In use, an earthed sleeve 24 carrying a sweep coil 25 surrounds the space 15. A metal disc 22 provided with a diametric slit (23) is disposed between the coils 13, 14. As shown in Fig. 4, the induction head is located within a cylindrical recess 33 in the base of a dewar vessel 34 containing liquid helium. A potentiometer (not shown) in the D.C. supply S of super-conducting solenoid 35 allows adjustment of the polarizing field. The sample may be rotated by an air driven turbine. When used in a magnetometer, the frequency of the transmitter is adjusted until resonance occurs whence the magnetic field strength is deduced. The coils may be arranged one on each side of the sample receiving spaced and matching and turning circuits (not shown) may be located within the housing 30. The holes 20 may be triangular or slot-shaped.
