Filed: 1935-12-02
Abstract: 464,451. Charging batteries. ROSS, T. W., PEDLEY, D., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Dec. 2, 1935, No. 33378. [Class 38 (iv)] In a battery-charging system a thermal relay operates, when the battery is fully charged, to start a motor which first reduces the charging rate and then after a predetermined adjustable interval cuts off the charging current. In the system shown in Fig. 1, the battery 10 is charged from an A.C. source 2 through a transformer 3 and rectifiers 4, the transformer secondary having a tapping controlled by a switch 6 by which the charging rate may be reduced. The switch 5 is closed by hand to start the charging and, when the battery is fully charged, the thermal relay 8, arranged, together with an adjustable resistance 9, across the battery terminals, closes a switch in the circuit of the motor 7 which first operates switch 6 and later opens switch 5. The mechanism for effecting this is shown in Fig. 2. Motor 7 is geared through slipping clutch 14 to shaft 13 carrying a disc 15 with a pin 29 which, at the end of the timed period, trips latching lever 21 and allows lever 18 to open switch 5. The length of the interval is determined by the adjustment of lever 16 on disc 15, the two being clamped together by nut 17. When starting, the charging disc 15 and lever 16 are turned by hand until the end of the lever engages pin 21<a> on lever 18 so that switch 5 is closed and held closed by latch 21. At the same time pin 35 on lever 16 engages lever 34 and operates switch 6 to the full charge position against the pull of spring 30. When charging is complete and motor 7 starts, disc 15 and lever 16 commence to rotate and first release lever 34 so that switch 6 can be operated by spring 30 to reduce the charging rate. After an interval determined by the relative setting of disc 15 and lever 16, pin 29 carried by disc 15 trips lever 18 so that switch 5 opens and charging stops.

Title: Improvements in and relating to multi-channel signalling systems
IPC: H04J3/04
Filed: 1946-11-21
Abstract: 652,357. Cathode-ray tubes. GENERAL ELECTRIC CO., Ltd., ESPLEY, D. C., and LEVY, M. M. Nov. 21, 1946, No. 34506. [Class 39 (i)] [Also in Groups XL (b) and XL (c)] In a multi-channel pulse signalling system for operating N channels each at a recurrence frequency F, N/a channel modulating or demodulating devices are employed, each operating upon a different group of a channels equally spaced over the channel pulse recurrence period ((a being greater than unity). Distributors are provided for coupling each channel to its associated modulating or demodulating device at the appropriate time. Fig. 2 shows a master generator 10 generating a sine wave oscillation at 45 kc/s. A two-phase oscillation derived from this wave is applied to the deflecting coils, 37, 38, of a cathode-ray tube modulator 34 to produce a circular trace. The modulator 34 comprises twelve modulating electrodes M, each of which co-operates with an inclined slot arranged annularly in a plate 36 located in front of a collecting electrode 35. A two-phase 9 kc/s. sine wave derived from the 45 kc/s. wave is applied to the deflecting coils 28, 29 of the cathode-ray tube distributers 25, 26, of the type described in Specification 618,384. The ten anodes D of each distributer are arranged to overlap one another in two zones one within the other, the cathode-ray being caused to rotate in a conical path and deflected radially by means of a 45 kc/s. square wave applied to outer conical electrode 30, 31, so as to engage anodes in the two zones alternately. A gating device comprising section G<SP>1</SP>, G<SP>2</SP>, G<SP>3</SP>, as described in Specification 652,356, [Group XL (b)], is also employed. In operation, the cathode-ray in tube 25 is rotated at 9 kc/s. and the square wave oscillation at 45 kc/s. serves to deflect the ray from one ring of five anodes to the other. A pulse is therefore generated at each of the anodes once every <SP>1</SP>/<SP>9000</SP> second and has a duration including at least three channels. A pulse of this kind from anode D<SP>1</SP>, capable of handling channels 5, 7, 9, triggers the first valve of each of sections G<SP>1</SP>, G<SP>2</SP>, G<SP>3</SP> of the gating device so that signals applied at terminals S5, S<SP>7</SP>, and S<SP>9</SP>, pass down lines M<SP>5</SP>, M<SP>7</SP>, M<SP>9</SP>, simultaneously, to the modulator 34, modulation of the beam being effected as the beam passes the slots corresponding to channels 5, 7, 9. Thus, by means of the gating devices G and the tubes 25, M, signals may be transmitted over sixty different channels. In a 120 channel system, these channels form the odd-numbered channels the even-numbered channels being provided by means of further gating circuits and a further distributer modulator tube. Specification 506,877 also is referred to.
