Title: Rotary actuator
Inventor: CLARIDGE ANTHONY NORMAN
IPC: H01F7/14
Filed: 1982-02-17
Abstract: A rotary actuator (10) comprises one or more units, each of which consists of a rotor (16) (17) mounted for rotation within a stator (20). Each stator (20) (21) has semi-circular cross-section surfaces (24, 25), the axes of which are spaced apart and parallel. Each rotor (16) (17) has two part circular cross- section surfaces (18, 19) which confront the semi-circular cross-section surfaces (24, 25) of the stator and an axis of rotation of which is parallel with coplanar with and situated mid-way between the axes of the two semi- circular cross-section surfaces (24, 25). The arrangement is such that upon rotation of the rotor the gaps between the confronting surfaces (18, 19, 24 and 25) of the rotor and stator progressively decrease from a maximum value to a minimum value. A coil (28) is contained within each Stator (20) (21) and when electrically energised, creates a magnetic field which causes the rotor (16) (17) to rotate to reduce the gaps from the maximum to minimum values. <IMAGE>

Title: Aircraft
Inventor: CADOUX ROY EDWARD
IPC: B64F1/26
Filed: 1982-06-17
Abstract: On board an aircraft, a computerised system for at least partly automating noise-alleviation procedures carried out after take-off of an aircraft. In the exemplary embodiment, data relating to a particular airport and/or runway thereof and any nearby noise-sensitive locations is input to the system on say a punched card. Thereafter, the system uses this data and data gathered from the aircraft navigation system to calculate an optimum throttle cut-back time which equalises the two noise peaks sensed at the noise-sensitive location respectively during approach to the location just before the cut-back and when the aircraft passes the location. The system gives a signal to the pilot at the optimum throttle- back time, and/or a control signal direct to an automatic throttle control system. <IMAGE>

Title: Thermal fuse
Inventor: HOLMES EDWARD SYDNEY BAKER
IPC: H01H85/02
Filed: 1984-06-04
Abstract: A fuse for responding to external temperatures to interrupt an electrical circuit, for example for interrupting a telephone battery feed in response to the temperature of a battery feed resistor, comprises a substrate 10 carrying a pair of electrodes 12, 14 defining a gap 20 between them. A fuse link 26, for example a gold strip, extends across the gap to interconnect the electrodes electrically. A film of solder 28 overlies the fuse link and overlaps at least partly at least one of the electrodes. The fuse link is soluble in the molten solder so when the temperature of the solder paste exceeds its melting point, it melts, dissolves the fuse link, and retreats from the gap to sever the electrical connection between the electrodes. The fuse and a resistor whose temperature is to be detected, may be provided on a single substrate. <IMAGE>
