Filed: 1949-03-16
Abstract: 671,164. Dynamo-electric machines. BRITISH THOMSON-HOUSTON CO., Ltd., WALKER, J. H., and GIBBS, W. J. Feb. 21, 1950 [March 16, 1949], No. 7199/49. Class 35. A synchronous frequency changer of the single- or double-unit type has a field winding arranged in three sections, the current in each of which is displaced relatively to one another. The Figure shows a single-unit frequencychanger, the stator windings 2, 4 of which are wound so as to be connected to 25- and 60-cycle mains respectively. The rotor carries two exciting windings 6, 7 co-operating with the stator windings 2, 4, respectively. The current in section of the winding 6 is displaced by 120 degrees and is fed by the exciters 9, 10, 11 in conjunction with 3-point cross-connected potentiometer 13. Thus the exciting winding 6 has means to displace angularly the axes of its poles relatively to those of the other winding. Two of the sections of the other rotor winding 7 are fed from the same pole of an exciter 20 while the third section of the winding 7 is connected to the other pole of the exciter 20 and to one of the incoming leads of the winding 6. Instead of the exciters and potentiometer, rectifiers and transductors or a single D.C. generator having three brushes uniformly displaced over its commutator, may be used. A motor 22 drives a shaft on which all the exciters are mounted. For starting purposes, the winding 7 may be connected to a liquid resistance 21. The windings in the rotor(s) and stator(s) may be interchanged.

Abstract: 312,715. Fletcher, G. H., Brookes, R.. and Associated Electrical Industries, Ltd. March 9, 1928. Exciting; motors, controlling.-In a system of regenerative braking for motors with separate excitation, the field windings are divided into sections which are connected in parallel for motoring and in series for generating and the coils are so disposed on the magnets as to be magnetically balanced in both cases. The arrangement may be combined with the use of tappings and resistances, as described in Specification 306,726, and may be applied to the system of duplex traction having two separate two-motor equipments described in Specification 313,427, [Class 38 (iii), Electric motor control systems &c.]. Figs. 1 (Prov.) and 2 (Prov.) show a balanced arrangement of tapped coils for a motor having four poles N', N<3>, S<2>, S<4> with inter-poles (similarly designated) having separate windings brought, out to terminals A+, A<1>. The two sections of the main coils are brought to terminals +1, FF1- and +2, FF2-. The taps are brought out at WF1-, WF2- and are not employed during the series regenerative working. With parallel motoring connection, the circuit from +1 to FF1- includes a radially outer or back coil on each of the vertical poles N<1>, N<3> and an inner or front coil on each of the horizontal poles S<2>, S<4>. Similarly the circuit from +2 to FF2- includes back and front coils on the horizontal and vertical poles respectively so that magnetic balance is obtained notwithstanding different pole leakages between front and back coils. With the taps in use, a similar balance is obtained. Fig. 1 (Comp.) shows a series-parallel and tapping arrangement, as described in Specification 306,726 for giving three field strengths in which the above arrangement may be employed. The motor A has its field coils in two sections f<1>, f<2> which may be connected in series or in parallel by a switch Z and these, together with resistance taps fr, are connected to four switches K<1>, K<2>, K<5>, K<6>. With K<1>, K<2> closed, full field is obtained; medium field is given by closing all four switches; and weak field by closing K<5>, K<6>. The switches Y<1>, Y<2>, Y<5>, Y<6> are for reversing the connection between the field and armature circuits in known manner, and the switches C<4>, C' are for connecting in the exciter E for regenerative braking with the field sections in series. The switch Z may be operated by contacts on the regenerating drum of the main controller such that the parallel connection of the fields is given the regenerating drum is " off " and the series connection in all braking positions of the drum. The switches K<1>, K<2>, K<5>, K<6> are preferably coupled in pairs to ensure simultaneous changes in the two field sections. Specification 313,429 also is referred to.

Title: Improvements in and relating to circuit arrangements for the correction of pin cushion distortion in display tubes
IPC: H04N3/237
Filed: 1967-02-16
Abstract: 1,174,183. Cathode-ray tube circuits; sawtooth circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 16 Feb., 1967 [19 Feb., 1966], No. 7524/67. Headings H3P and H4T. In an arrangement for correcting pin-cushion distortion utilizing a known circuit including a transductor 9 (Fig. 1) having a non-linear B/H characteristic, distortion of the field scanning sawtooth wave, which is supplied to the field output transformer 5, due to the varying inductance of winding 16 of the transductor, is compensated by the provision of a third winding 26 coupled to winding 16 on the transductor core (Fig. 2, not shown) the voltage induced in which is introduced, with proper regard to polarity, into the negative feed-back circuit of the field amplifier stage 4. This results in a predistortion of the sawtooth across winding 18 which distortion is then cancelled by the undesired component due to winding 16. As shown, winding 26 is connected between the field sawtooth capacitor 21 and a feed-back winding 25, the amount of feed-back being such that the control grid of 4 receives about <SP>1</SP>/ 10  of the amplitude of the sawtooth voltage across capacitor 21. The actual waveforms developed in the operation of the circuit are described with reference to Figs. 3 and 4 (not shown). In a modification, the coils 25 and 26 are connected in parallel instead of in series (Fig. 1a, not shown). Fig. 5 shows a modification in which an RC circuit comprising resistors 31, 32 and capacitor 33 is included in the circuit of the feed-back winding 25 to eliminate line fly-back pulses due to the line deflection coils 3 (fed from line sawtooth generator 1) these resistors together with a further capacitor 34 also forming a peaking network to eliminate pulses from the negative feed-back voltage. Fig. 5 includes an additional winding 35 on the transformer 5 which is utilized as a feed-back winding to make the field deflection stage, triggered by field deflection pulses supplied to capacitor 36, self-oscillating. Fig. 6 shows a further arrangement, not employing negative feed-back, which utilizes a boot-strap stage 38, the cathode resistor 39 of which supplies a sawtooth voltage (produced across capacitor 21) to the grid of a triode 4<SP>1</SP> forming the field output stage, the arrangement being self-oscillating. To compensate for the effect of winding 16, the voltage across winding 26 is introduced into the grid circuit of stage 4<SP>1</SP> and line fly-back pulses are removed by the network comprising resistor 44 and capacitor 43. In all of the embodiments parabolic and " S " components are added in known manner. The thermionic valves may be replaced by transistors.
