Title: A rotor for an electrical machine
Inventor: LYNCH CEDRIC
IPC: H02K23/54
Filed: 1986-12-18
Granted: 1990-01-04
Abstract: There is described a rotor (14) for an electrical machine, the rotor having a current-carrying winding comprising a plurality of circumferentially distributed winding portions which lie in at least one plane (A-D) perpendicular to the rotor axis (16), and extend from a radially inner region to a radially outer region. A commutator is provided by surfaces of the winding portions at the inner region, and the winding is formed from a plurality of conductive sections, each having ends which lie at said outer region, interconnections between the winding sections being made only by way of those ends. Thus, soldered connections made between the winding sections will be remote from the commutator, which is the main source of heat for overheating, and moreover will be at positions where air cooling due to rotor movement is greatest. Air gaps between the winding portions at the outer region aid this cooling affect even further.

Title: Electrical machine
Inventor: SPOONER EDWARD
IPC: H02K41/06
Filed: 1987-01-20
Granted: 1990-06-06
Abstract: An electrical machine comprising a member (3) of magnetic material, and a stator (1) supporting windings which when energised generate magnetic fields in a gap defined between the member (3) and the stator (1). The stator (1) supports at least two windings each of which is energisable to generate a different number of magnetic pole pairs from the other winding or windings. At least one winding comprises a plurality of subwindings arranged to be energised by respective phases of a polyphase current so as to generate a moving magnetic field in the gap. A resultant magnetic field appears in the gap which is a moving magnetic field that is the sum of the magnetic fields resulting from energisation of each of the windings. The resultant distribution of attractive force between the two members (1, 3) may have a long wavelength compared to the winding pole pitches, which is of value in harmonic drive type devices, or may rotate at twice the angular frequency of a supply current, which enables high speed operation.

Title: Loudspeaker systems
Inventor: NEVILL STUART MICHAEL
IPC: H04R1/28
Filed: 1997-05-02
Granted: 2001-09-12
Abstract: The loudspeaker system includes a loudspeaker drive unit (2) and a tube (4) acoustically coupled to the rear of the loudspeaker drive unit for leading away and absorbing sound waves produced at the rear of the loudspeaker drive unit. The tube is acoustically coupled to the loudspeaker drive unit by a hollow resonant enclosure (6) and the loudspeaker drive unit is mounted at an aperture (8) in an external wall of the enclosure. The tube communicates with the interior of the enclosure and extends outwardly from the enclosure. There is a significant change in acoustic impedance where the tube communicates with the interior of the enclosure. The fundamental resonant frequencies of the enclosure and the tube each lie between the first and second frequencies but the Helmholtz resonant frequency of the tube, when its distal end is open, lies below the first frequency. The effect of the enclosure is to "short circuit" sound at the frequencies of the higher order resonances of the tube so that those resonances are not excited to any significant extent.

Patent IT-1058345-B (IT)
IPC: B62D49/02
Filed: 1976-03-12
Granted: 1982-04-10
Abstract: A telecommunication switching arrangement is described wherein each seizable switching component, i.e., a component in an idle condition, is so marked by application of an idle potential to a test point by means of a seizing circuit in that switching component. The busy condition is indicated by the absence of the aforementioned potential. The condition of the switching component is sensed by a test switching device having an internal impedance corresponding to that of a preceding switching component. The latter device accomplishes its task by completing a test and seizure circuit including the aforementioned test point. If a switching component being tested is already seized by another switching component, it will have been blocked by a blocking circuit in the other switching component. Such blocking is brought about by applying a potential differing from the idle potential from the blocking circuit via an auxiliary test switching means in the other switching component, which has an internal impedance identical to the test switching means. For seizure, the seizing circuit in each switching component is fed from a constant current generator proportioned in accordance with the number of switching components testing that switching component. The foregoing proportion is the inverse of the number of switching components testing in parallel.
