Patent GB-763596-A (GB)
Abstract: 763,596. Electric dynamic balancing machines. RAVA, E. April 10, 1953 [April 11, 1952], No. 9786/53. Class 40 (1). [Also in Group XXXIX] In a dynamic balancing machine, a testpiece P is horizontally rotated on displaceable supports 3, 4 which are connected to moveable iron cores 7, 8 of vibration detectors having relatively fixed coils 9, 10, and the vertical components of vibrations are converted into an electric signal which is compared over potentiometers with a test voltage of known amplitude and phase, this voltage being obtained from a single phase alternator 25 driven with the test-piece by a motor 1. As shown in Fig. 1, the coils 9, 10 are connected by a change-over switch K with potentiometers 15, 16 which effect corrections so that the supports 3, 4 virtually coincide with balancing planes A-A, B-B. The A.C. test voltage is adjusted by a potentiometer 19 so that a scale 131 of a correction potentiometer 31 is accurately calibrated in terms of weight to be applied or depth of hole of given diameter required in the balancing plane A-A. A similar calibrating function in respect of plane B-B is provided by potentiometer 20. The switch K also connects the coils 9, 10 in such a way that the full output of one detector is added to a part of the output of the other detector, the output relationships being reversed when the switch is changed over. The combined outputs are applied at the calibrated potentiometer 31, according to the switch position, in opposition to the test voltage adjusted by 19 or 20, and a direct indication of the balancing correction required is given by the setting of 31 necessary for a null condition to be indicated by a rectified moving coil meter 28. Sensitivity is adjusted by a variable resistance 30. The null condi- . tion is also dependent on the absence of phase displacement between the alternator and vibration detector outputs, and adjustment in this case is effected by rotation of the alternator stator, its angular position when final balance is obtained denoting the peripheral points on the balancing planes where correction should be effected. In constructional detail, Figs. 2 and 4, the motor and alternator are arranged in a common casing and the alternator stator is rotated by a hand wheel 39. The supports comprise V-shaped bronze or plastic units 45 which are carried on adjustable standards 41 by resilient rubber pads 43. A vertically guided rod 46 attached to a support carries the iron core 47 of an inertia-type vibration detector comprising an annular magnet 64, fixed armature 63 and a coil 48 mounted in a body 60 (see Group XXXIX).

Patent GB-2066961-A (GB)
Title: Electronic capacitive liquid level gauge
IPC: G01F23/26
Filed: 1979-12-28
Abstract: The invention consists of a method of sensing, measuring, and providing appropriate digital outputs of the height of a liquid level, either in a closed container, or in a natural environment, such as rivers or the sea. The method used is to discriminate between the electrical capacity to earth, or to a common sensor, of discrete sensors placed vertically in the liquid, when they are above the surface of the liquid or below it. The sensors are insulated from the liquid by any suitable dielectric and are spaced vertically at any desired interval. They can be simple plates of metal foil. The count of sensors indicating "below the surface" or of those indicating "above the surface" or the dividing line between the two, indicates the depth. The method used in the application involves pulsing each sensor sequentially and resolving the electronic capacity indication as being "above the surface" or "below". <IMAGE>

Patent GB-2086102-A (GB)
Title: Energy economizer for polyphase induction motors
IPC: H02P27/02
Filed: 1980-10-10
Abstract: A standard three phase induction motor 10 starts with all three of its input connections connected to the three phase power line. Two of these connections are through triacs 5, 6 which remain continuously conducting below said motor's particular most energy-efficient speed, which is above about 95% of synchronous speed. This ensures full starting torque and undiminished overload handling capability. The triacs 5, 6 in response to a control signal, may open the circuits over a sufficiently wide portion of the sine wave input voltage to substantially maintain said particular efficient speed under all rated load conditions. To ensure smooth operation and maximum energy savings, the two triacs 5, 6 conduct differently at very light motor loads. A DC control voltage which determines the operation of the triacs is generated by a frequency discriminator circuit 17 which receives its information from a load detecting device 18 that is frequency modulated by load/speed related properties inherent to induction motors. Specification 2006484A discloses a similar system applied to a single phase induction motor. <IMAGE>
