Inventor: BOLLARD DAVID ROOKSBY
IPC: G01S7/22
Filed: 1960-01-13
Abstract: 919,646. Cathode-ray tube circuits; pulse radar; transistor step wave circuits. DECCA Ltd. April 4, 1961 [Jan. 13, 1960], No. 1291/60. Classes 40 (6) and 40 (7). A cathode-ray tube (C.R.T.) display arrangement comprises a C.R.T. with a main deflecting system for repetitively scanning the C.R. beam in a series of traces across the C.R.T. screen, an auxiliary deflecting system for effecting deflection of the C.R. beam in two transverse directions, the auxiliary deflecting system including means generating two waveforms, the instantaneous amplitudes of which represent co-ordinates in the transverse directions to define a selected character, the waveforms having a duration much less than (e.g. 1/400) the duration of a main display scan, and means for applying the two waveforms representative of the selected character simultaneously to respective deflector means. The waveforms may be applied during the main scan or in the inter-scan period. In the embodiments the main and auxiliary deflecting systems each comprise orthogonal coils. As applied to a pulse radar with P.P.I. display an echo pulse from receiver 13 passes through a video gate 27 so as to pass pulses which represent targets within a chosen bearing and range tolerance of a predetermined position. Gate 28 inhibits for a time all pulses passed through gate 27 after the first pulse; thus in each revolution of the radar aerial a single pulse corresponding to the echo of a selected target passes into waveform generator 22 which then generates two waveforms, each of which comprises a series of rectangular pulses which overlap slightly to ensure that the C.R. beam does not return to its datum between the pulses. Successive values of pulse amplitude represent successive coordinates, and the trains, Fig. 4, are applied to orthogonal deflector coils 20, 21. Generator 22 comprises an inductor-capacitor delay line from the taps of which connections are taken to the bases of transistors 43, 44. . . . Each input pulse to the line is arranged to be negative and each transistor is connected as an emitter follower with resistor 142, which prevents excessive loading of the transistor when Zener diode 42 conducts; the Zener diodes ensure equal pulse amplitudes on lines 46, 47 . . . which are connected to amplitude adjusting circuits 49, 50 . . . ; each such circuit comprises resistors 53, 54 . . . commoned to the collector of a transistor 57, the base of which is connected via resistor 58 to character selection means.59 providing a switching bias to select the desired pair of amplitude adjusting circuits. The outputs of circuits 49, 51 . . . and 50, 52 are connected to respective deflection coils 20, 21 via resistive-feedback amplifiers 64, 65. Groups of characters may be displayed. The display of a computer output is outlined, Fig. 5 (not shown).

Title: Improvements in and relating to alternating current electric motors
IPC: H02K27/08
Filed: 1921-01-10
Abstract: 157,723. British Thomson - Houston Co., Ltd., (Assignees of Altes, W. C. Korthals-). Dec. 22, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Alternating-current commutator machines; exciting. - An alternating-current commutator motor has two sets of brushes, such as 8, 8<1>, 9, 9', Fig. 1, each connected with compensating windings 6, 6<1>, exciting windings 5, 5' and reactive coils 10, 10<1> in parallel on the commutator in such a manner as to avoid local short-circuits through the brushes. The compensating and exciting coils are wound in a slotted stator of the usual induction motor type, as shown in Fig. 6, and the brush studs need be arranged around a part only of the commutator, as in Fig. 8, where the brush pairs 58, 59 are arranged opposite handholes 60, 61 in the upper part of the motor casing. In the form shown in Fig. 1, the reactive coils 10, 10' form the secondaries of the transformer through which the motor is supplied with energy from the mains 12, but in an alternative arrangement each pair of brushes 8, 8<1>, 9, 9<1> is closed through a reactance, the mid-points of the reactances being connected to the mains, one directly and the other through the compensating and exciting coil groups connected in parallel. Or the compensating coils may be split into two parts each comprising two portions in series with one of the brushes. The two portions are joined together on their side remote from the brushes, and they are connected to the mains, one directly and the other through the exciting coils in series with a reversing switch. In the arrangement shown in Fig. 4, the brush pairs are connected to reactances 35, 35<1>, the mid-points of which are led to taps on the secondary side of the supply transformer 41, the exciting and compensating coils 37, 37' and 36, 36<1> being paralleled and connected in series with a portion 40 of the same secondary coil. The Specification also describes the application to a motor for starting a frequencychanging set comprising a synchronous motor coupled to a generator having a different pole number. This arrangement shows a throw-over switch for starting the commutator machine as a motor on the alternating-current mains on which the synchronous motor ultimately runs, and for subsequently throwing it over to a separate pair of mains to which it supplies continuous current as a generator driven by the frequency-changing set. The stator windings, Fig. 6, are of full pitch lap type and comprise exciting coils, shown in light lines, separated bv an unwound zone a, j somewhat greater than the angle between the brushes, and compensating coils, shown in heavy lines. Coils with different numbers of turns are used, whereby the armature reaction may be accurately compensated over a portion of the pole angle and over-compensated to ensure good commutation over the remaining angle. In the example shown, the full and dotted line coils have 5 and 7 turns respectively so that the slots c, h contain 14 compensating turns and the slots d, e, f, g 12 turns.
