Title: Radial displacement detection device for a magnetic bearing
IPC: G01B7/312
Filed: 1974-01-17
Abstract: 1418261 Measuring displacements electrically SOC EUROPEENNE DE PROPULSION 17 Jan 1974 [18 Jan 1973] 02270/74 Heading G1N The radial displacements of a rotor 2 (Fig. 1) mounted on a fixed shaft 4 on magnetic bearings 3 and driven by a motor 5, are measured at each end 2a, 2b of the rotor by a detector 1 comprising a fixed disc 1a (Fig. 2) carrying a symmetrical arrangement of U-shaped cores 1d-1k, each wound with a coil whose inductance is determined by the size of the air gap between the ends of the U-shaped core and a surrounding magnetic ring 2d attached to the rotor 2. The cores 1d-1g are symmetrically located at 30 degrees to an XX' axis on the disc 1a, and the other cores 1h-1k are similarly located with respect to a perpendicular YY' axis on the disc. The coils 1d-1g are wound in series with a wire 11, and the coils 1h-1k are wound in series with a wire lm, to give the polarities shown when energized with one half-cycle of an A.C. supply. Centre taps 1n, lo, respectively are provided for each group of windings. When the rotor 2 is displaced radially, e.g. to the right along axis XX', the inductances of coils le, 1d increase and the inductances of coils lf, 1g correspondingly decrease, producing a corresponding signal on centre tap 1n. Similarly radial displacement along axis YY, produces a corresponding signal on centre tap lo. If the rotor 2 is not perfectly circular, the changes in the air gap between the rotating ring 2d and the static disc 1a form a series of harmonics of the fundamental displacement signal. Considering coils 1d-1g measuring XX' displacements, all the even harmonics produce equal inductance changes in the coils on either side of the centre tap In and therefore produce no resultant output signal on that lead. Also the pairs of coils 1d, 1e and 1f, 1g on each side of the centre tap 1 n are displaced by 60 degrees and connected in series, whereby the effects of the third harmonic are eliminated. By further duplication of coils and selected spacing it is possible to eliminate the effect of further odd harmonics.

Filed: 1939-01-25
Abstract: 524,245. Friction gearing. COLE, Ltd., E. K., and MARTIN, A. W. Jan. 25, 1939, No. 2546. [Class 80 (i)] [Also in Groups XXXVI and XXXVII] In wireless receivers employing motor operated push button tuning of the kind in which the motor operates contacts individual to the push buttons to disconnect itself when on reaching a predetermined tuning position and to reverse its drive when the position is overrun, chattering in the reverse drive is eliminated by automatically introducing reduction gearing giving a slow motion drive in the reverse direction. A commutator 3 mounted on the shaft 2 of the tuning condensers and provided with the usual contact makers 23 on a segment 24 is driven through friction gearing 22 from a shaft 18. The latter is driven from a motor 4 through gearing comprising a bracket 12 carried by a gear wheel 6 and provided with a stud 14 which engages in a slot 13 formed in an arm 15 carried on a pivot 16 secured in a bracket 17 mounted on the shaft 18. A lost motion slow drive is thus obtained while the stud 14 moves down the slot 13 but a direct drive takes place when the stud engages the end of the slot. The periphery of the disc 20 is formed with flattened sides so that during the direct drive the disc is out of engagement with friction discs 19 on the shaft 18 but during the slow motion drive is engaged thereby thus giving additional friction during the fine tuning. The spur wheel 6 is frictionally held against an abutment 8 on a shaft 7 by a spring 9 and is provided with openings accommodating springs 10, 11 constituting a shock absorber in the drive.

Title: Improvements in or relating to limiting circuits employing transistors
IPC: H03D3/14
Filed: 1957-01-25
Abstract: 809,390. Transistor limiter circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 25, 1957 [Jan. 28, 1956], No. 2767/57. Class 40 (6). A transistor limiter circuit comprises a tuned input circuit connected to a limiter of the type in which the limiter bias is determined by the incoming signal and also connected to the input of a transistor which is arranged to operate as a collector limiter and which, by variation of its input impedance, effects further limitation of the input signal. In Fig. 2 a series tuned input circuit 1, 2 is connected to a limiter circuit comprising rectifier 7 capacitor 5<1> and resistors 15, 6<1>. The D.C. voltage which is thus developed across resistors 15, 16 is used to bias the limiter. Part of the voltage is also used as the collector bias for a grounded base transistor amplifier 3 and part as the emitter bias, the latter serving to maintain the emitter conductive during negative half cycles of the input wave so as to complete the series tuned input circuit. The collector bottoms during peaks of the input signals so as to further limit the signal amplitude and this reflects an increased impedance at the emitter which damps the series tuned input circuit causing still further limitation. The bias for the emitter may be omitted in which case a rectifier must be connected between emitter and base to complete the input tuned circuit during negative half-cycles (Fig. 1, not shown). In Fig. 3 (not shown) a parallel tuned input circuit is used and the common base amplifier is replaced by one of common emitter type.
