Abstract: 233,741. Gramophone Co., Ltd., and Buckle, H. L. T. Nov. 21, 1923. Drawings to Specification. Speed, regulating; record tracks, form of.-Relates to disc machines for recording or reproducing sound, of the kind in which, during the operation of the machine, the angular speed of the turntable increases, but the rate of increase is insufficient to produce a constant " needle speed." According to the invention, the angular speed of the turntable, for any position of the needle, is not less than that which is sufficient to overcome the drag of the needle, (e.g. with the needle at 6 inches from the record centre, the speed is not less than 35 revolutions per minute) whilst the needle speed is never allowed to fall below the minimum necessary for the satisfactory cutting or reproduction of a record. This minimum speed is stated to be 75 feet per minute. The angular speed of the turntable need not be increased until some time after the operation of the machine has started. Preferably the variation in the speed of the turntable is effected by moving the friction pad of the centrifugal governor by the means described in Specification 233,406, and the governor is preferably of the kind described in Specifieation 216,571. Explanatory graphs accompany the Specification.

In a telegraph exchange of the type in which each bit is transmitted simultaneously on a combination of channels unique to a particular unit in the exchange, each calling subscriber's transmitter can be set to only a number of combinations less than the total number used in the exchange. As described, when a subscriber Tnl wishes to communicate with another, e.g. Tn500, dialling pulses from Tnl cause unit ZES to seize one of a number of magnetic core connector sets which form unit ZVS; the number of connector sets is less than the number of subscribers. Unit ZES also sets the connector set transmitter to transmit on a combination of channels representative of the called receiver KS500 in decimal code, and sets the transmitter KS 1 of the calling subscriber to transmit on a combination SV representing the seized connector unit in excess-3 code. Data from Tn1 then passes from KS1 via unit UCS, which converts the excess-3 code to decimal, to the selected connector set. From thence it passes over channels L to unit UCE, which converts from decimal to excess-3 combinations, and over the multichannel line EV to the receiver KE500 of the called subscriber Tn500. The channels may be different frequencies or separate leads.

Filed: 1971-06-28
Abstract: 1398383 Starting fluorescent lamps GENERAL ELECTRIC CO Ltd 28 June 1972 [28 June 1971] 30227/71 Heading H2H A circuit arrangement for starting a discharge lamp comprises resonant circuit means connected between the supply and lamp terminals. When an A.C, source is connected to terminals 2, 3 a voltage is applied to the gate of a triac TR1 by way of a resistor R2 causing conduction thereof. A capacitor C2 then resonates with the primary winding of a transformer T1 at a frequency of the order of 10-15 KHz. The Q-factors of the capacitor and transformer are chosen high so that the circuit will ring freely for a sustained period-say 15 cycles, the amplitude of the second pulse being at least 70% of that of the first and of five to seven of the pulses at least 40% of that of the first, in other words, a highly damped oscillation. The pulses so produced are stepped up by the transformer T1 and applied to the mercury discharge lamp. If desired a small capacitor C x  may be connected across a portion of the primary winding of the transformer T1 thereby producing a series of secondary oscillations. Numerous modifications of the circuit are described, using a back-to-back thyristor and diode instead of a triac; using a firing circuit including a second triac to fire the triac TR1; omitting the resistor R2; using Zener or Shockley diodes instead of the second triac or using a cut-off circuit to permit the starter circuit to operate for a limited period only. Two lower voltage triacs in series may also be used and the firing circuit may include a unijunction transistor. In other embodiments the starting pulses may be produced in a resonant circuit in parallel with the discharge lamp.
