Title: Improvements in or relating to electric generating systems
Inventor: ABDEL-KADER FATHY ELSAYED AHME
IPC: H02K17/42
Filed: 1986-10-01
Abstract: The load characteristic of a generator is improved by the connection of the primary P of a step-up autotransformer A to its output terminals T4,T5, a capacitor C4 being connected to the secondary S of the autotransformer. The generator may be an induction type, or preferably a reluctance type. If a three phase generator is used, a star or delta connected three phase transformer is coupled across its outputs and star or delta connected capacitor are coupled across the transformer secondaries (Fig. 3). The primary turns of the transformer are selected to produce saturation at no load. Compared to prior art use of capacitance without the autotransformer (Fig. 1), the present system gives a reduction in the required capacitance value, new-constant output voltage, reduction of no-load current and iron loss, and increase of generating output current and power. <IMAGE>

Title: Active sound control apparatus
Inventor: ELLIOTT STEPHEN JOHN
IPC: G10K11/16
Filed: 1986-10-07
Abstract: To reduce noise inside a motor car passenger compartment, two loudspeakers 371, 372 are driven by signals derived from a reference signal x(n) by adaptive filtering carried out by a programmed microprocessor and memory unit 36 which adapts the filtering in dependence on error signals e1(n) from four microphones 421, 422, 423 and 424 distributed in the passenger compartment. Reference filtering coefficients are initially determined by analysis of finite impulse responses when white noise is acoustically coupled from the loudspeakers 37 to the microphones 42, a white noise generator 48 being coupled to the unit 36. The reference signal x(n) is restricted to one or more selected harmonics or subharmonics of the fundamental noise frequency by a filter 34 which tracks the selected frequency. The selected frequency may be obtained from a coil 31 in the ignition circuit. <IMAGE>
