Title: Improvements relating to call meters for telephone systems
IPC: H04M17/02
Filed: 1936-06-04
Abstract: 476,232. Substation apparatus. SODECO SOC. DES COMPTEURS DE GENEVE. June 4, 1936, No. 15579. Convention date, June 8, 1935. [Class 40 (iv)] A telephone set in a restaurant or other public place has the dial springs normally shortcircuited at contacts 351, 35<11> which are opened when an attendant presses a button 42 and become closed again when the first metering impulse arrives from the exchange. Operation of the button 42 rocks a lever 44 which by means of a pin 46 rotates a segment 48 carrying a pin 49 which depresses the lower contact spring 35<11> as shown. An indicator carried by the segment 48 is brought into view to inform the caller that the dial is free. The segment 48 is latched in this position by a projection 51 on a lever 50 until the first metering impulse is received, when a pin 53 on the armature 2 of the meter magnet 1 rocks the lever 50 and releases the segment 48, so that the contacts 35<1>, 35<11> close again. After an unsuccessful call, the segment 48 may be released by operation of a second button 58 which acts on the lever 50 through a lever 59. If the metering arrangement is of the kind described in Specification 463,958, the operation of the button 42 also transfers the record on the trip counter, that is, the charge for the previous call, to the total counter.

Title: Improvements in the control of the power factor and voltage conditions of electric induction furnaces
IPC: H02J3/18
Filed: 1928-06-05
Abstract: 317,931. Davis, N. R., Burch, C. R., Capper, F. W., and Associated Electrical Industries, Ltd. June 5. 1928. Regulation, automatic; supplying consuming devices.-In electric induction furnaces, particularly high-frequency furnaces, in which the charge forms a transformer secondary and in which the power-factor is maintained at a desired value as the charge heats up by the automatic connection of one or more condensers into the furnace circuit when the power-factor tends to fall, a resistance is introduced into the field circuit of the supply generator just before each condenser is connected into circuit so as to reduce the voltage of the generator, thus allowing for the rise of voltage occurring when the condenser is connected up. A wattless-power relay controls a reversible motor 15 rotating a. drum controller 14 for the circuits of the switches controlling the condensers. The voltage in the furnace circuit is maintained constant by a voltage relay 19 controlling a reversible motor 10 operating a rheostat 8 in the field circuit 9 of the generator. The relay 19 is made inoperative. and the rheostat 8 is operated to increase the field resistance, prior to the introduction of a condenser. The needle 13 of the wattless-power relav contacts with the upper or lower contact 20 for leading or lagging power-factor respectively and so closes a circuit from a supply 18 through the control coil 34 of switches 35 in the armature circuit of the motor 15 and through one or other of the fields 16, 17 of the motor 15 and one or other of the relays 23, 24 with locking contacts 30, 30<1>. The drum controller with stepped contacts 52, o, a g all connected together is thus rotated until stopped by a contact 26 leaving the segment o after it has short-circuited the coil of the relay 23 or 24. The voltage relay 19 completes a circuit through a control coil 40 of switches 41 in the armature circuit of the motor 10 and through a field 11 or 12 of the motor 10 to rotate the rheostat arm 41a. For lagging power factors, operation of the switch 24 breaks the supply to the needle 36 of the relay 19 and energizes the field 11 through contacts 22' to rotate the arm 41a to increase the field resistance. Rotation of the controller 14 makes or breaks the circuits of the condenser switches at contacts I - - VII. When the circuit is closed at contact I, the switch 5 is energized through an adjustable contact 45 and a contact 44 carried by the arm 41a. The switch 5 introduces a condenser 2 in series with a resistance 7 into the furnace circuit 1 and energizes the switch 6. The switch 6 short-circuits the resistance 7. breaks the circuit of the coil of the switch 5 and completes a locking circuit at 48.
