Title: Improvements in and relating to regulators for electric motors
IPC: H02K17/30
Filed: 1927-06-17
Abstract: 272,948. British Thomson-Houston Co., Ltd., (Assignees of Jump, G. H.). June 21, 1926, [Convention date]. Systems for alternating-current motors only; electric braking; controllers, liquid.-Liquid resistance apparatus varying t.he slip of an induction motor automatically according to the load is controlled so as to move automatically to a highresistance position before the motor is switched on to the supply. When the motor is adapted to run as a braking generator by reversing the connections or by changing over to a direct-current supply, the invention ensures that the change cannot be made until the slip-regulator is in a high-resistance position. In the arrangement shown in the Figure, the liquid resistance 13 connected to the rotor circuit of the induction motor 10 is varied automatically by a torque motor 19 energized from a series transformer 20. The apparatus is moved to the full-resistance position, as soon as the motor stator switch 23 is opened, by the automatic lowering of an extra counterweight 29 actuated through a worm drive by an auxiliary motor 32, the lowering action of this motor being determined by auxiliary contacts 42 associated with the stator switch 23. After the main motor has started.. the extra counterweight is raised by reversal of the auxiliary motor through a second pair of auxiliary contacts 37, and the resistance apparatus is left nearly balanced by the permanent counterweight 16 so as to be under the control of the torque motor. For electric braking a switch 24 changes over the stator connections to a direct-current supply 25; relays and electrical interlocks are disposed so that the auxiliary motor and extra. counterweight come into action as described above to put in full resistance before the change-over.

Patent GB-1575543-A (GB)
Title: Methods of and apparatus for charging accumulator
IPC: H02J7/00
Filed: 1977-04-19
Abstract: The method for limiting the charging process, which charging process is carried out with a decreasing current using a stabilised charging characteristic, that is to say a charging characteristic which is independent of fluctuations in the power supply voltage, is intended to ensure complete charging as far as the battery-dependent end of charging, irrespective of the charge state and age of the battery. The method is intended to be uninfluenced by temperature changes caused by charging. At the start of the charging process, the charging current intensity is measured at predetermined time intervals and the respective differences between the two successive measurement results are formed. When a predetermined minimum difference between two measurement results is reached or undershot, a pulse is stored. The charging process is ended when a pulse is stored on at least two directly successive occasions. The method results in absolutely correct charging of both new and old batteries. The life of the batteries is significantly extended. <IMAGE>

Abstract: 586,534. Valve super - regenerative circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 8, 1944, No. 17154. Convention date, Sept. 8, 1943. [Class 40 (v)] A super-regenerative radio receiver comprises an input circuit feeding a first heterodyne converter for producing signals at an intermediated frequency, and a second heterodyne converter for converting the intermediate frequency by summation to a frequency at least 50 per cent higher than the input frequency, for application to a super-regenerative detector tuned to detect this high frequency. In Fig. 1 a super-regenerative detector 30 is preceded by two frequency conversion stages. A common local oscillator 10 is used for both conversion stages the first intermediate frequency being a difference heterodyne and the second intermediate frequency, being a summation frequency of the first intermediate and local oscillator frequencies. This summation frequency is greater than the frequency of the received signals and is applied to the detector. By appropriate tracking of condensers 6, 21 and 16 the second intermediate frequency is maintained constant throughout the tuning range. The detector is normally tuned to rectify amplitude modulated signals and by detuning condenser 33 may constitute a simple discriminator for frequency modulation. Fig. 3 (not shown) illustrates a modification in which the first intermediate frequency is maintained constant at 20 mc/s. and the local oscillator tunes from 62-70 mc/s., correct tuning being maintained by tracking condensers 6, 33 and 16.
