Title: Improvements in electrical rectifier systems
IPC: H02J1/16
Filed: 1944-05-31
Abstract: 590,370. Electricity supply. GENERAL ELECTRIC CO., Ltd., and THOMPSON, W. G. May 31, 1944, No. 10456. [Class 38 (iv)] Equalizing load.-The load on a rectifier system is equalized by a fly-wheel 2 driven by a motor 1 connected to the output side. of a rectifier 7. The motor has a shunt or separately excited winding and a winding in like sense in series with the rectifier output. The single motor may be replaced by a shunt or separately excited motor and a separate series motor drivably connected to the same fly-wheel. In the arrangement described, the shunt or separate excitation may be automatically controlled in response to variation of load on the motor 1, e.g. by a torque motor 12 and a resistor 11. The armature 1 may be connected to the rectifier side or the load side of theseries field winding or to a tap on this winding. As shown, reduction of load on a rolling mill motor 5 reduces the series field 6, whereby the flywheel 2 is accelerated and vice versa. If the armature current of the fly-wheel motor tends to become excessive, the torque motor operates to strengthen or weaken the field 9, depending on the direction of current through the armature 1. Preferably, the series field saturates on overloads; the shunt or separately excited field prevents overspeeding on light loads.

A selective positioning mechanism for controlling the final position of a type-wheel comprises two or more rotatable members serially connected to the type-wheel shaft by differential or epicyclic gear trains, each of which comprises planet gears meshing respectively with a sun gear and an internal annulus gear and means for continuously applying a drive torque to the serially connected members, the angular motion of one of the elements of each gear train or of the controlled rotatable member being variably or selectively determinable by movable or adjustable stop means to permit a predetermined angular motion under the applied driving torque. The type-wheel 10 is connected by a sleeve 11 to the sun-wheel 13 in mesh with planet gears 14 engaging an internally toothed annulus 15. The shafts of the gears 14 are mounted on a carrier 16 connected to the sunwheel 18 of the second epicyclic train. The planet carrier 22 of the final gear train is fixed to an abutment 38. The toothed annuli have respectively one, two, four ... projections 24, 25 associated with controlled abutments 26, 27 ... which on operation allow a full revolution, half a revolution, and so on, of the associated annulus, and the gear ratios are such that the resultant rotation of the shaft 11 is halved so that the release of the annulus 15 defines two positions of the type-wheel separated by 180 degrees. The aboutments 26, 27 ... are operated in accordance with the impulses of a fiveunit code, five gear trains being employed. To provide accurate positioning of the type-wheel 10 for the printing operation, a member 34 operated by the magnet 37 when the character is to be printed on the tape 35 has a tooth 33 engaging notches 32 which are formed in a disc member 31 attached to the type-wheel 10 and which correspond to the location of the characters on the type-wheels.

Abstract: 1,222,245. Amplifiers; voice switching. TELEFONAKTIEBOLAGET L. M. ERICSSON. 4 March, 1968 [15 March, 1967], No. 10464/68. Headings H3T and H4R. A push-pull transistor amplifier is protected against disturbing signals fed back into the output circuit by diodes supplied with a blocking voltage derived from a first blocking source, and when this is exceeded by diode current charging a capacitor. As shown, the diodes DA1, DA2 are forwardly biased and the amplifier acts normally. If switch S is opened the negative supply terminal is connected through R3 to the diodes to block transmission through the circuit lock in the forward and backward directions. If the blocking voltage is exceeded the diodes conduct and the collector-emitter paths of the transistors act as half-wave rectifiers to charge a capacitor C1 and thus increase the blocking voltage. The zener diode Z provides the base-emitter bias.
