Patent GB-2149211-A (GB)
Title: Electrical relays
Inventor: ELDRIGE PETER GORDON
IPC: H01H51/22
Filed: 1983-11-02
Abstract: The armature (14) of a relay is pivotably arranged in a coil (3) and operates contact sets (2) via a insulating link members (19). The armature pivots about an axis which is perpendicular to both the winding axis of the coil (3) and the direction in which the relay terminals (29, 30, 31, 12) project from the relay housing (1). The contact force of the contact set (2) is enhanced by means of a permanent magnet (7) located between two yoke pieces (6, 5), each having bent-over portions providing pole faces (15, 16, 17, 18), coupled thereby. In a monostable version (as illustrated) the pole faces (15, 16, 17, 18) of the pole pieces via which magnetic coupling to the armature (14) occurs are different in size, so that when the coil (3) is de-energised the armature (14) will always restore to the same position corresponding to the larger pole faces (15, 17 as illustrated). In a bistable version the pole face areas are the same so that the armature is held in its last set position upon coil de-energisation. <IMAGE>

Title: Manufacturing an electrical device
Inventor: TITTERINGTON JOSEPH BELL
IPC: H01L21/48
Filed: 1985-07-24
Abstract: Laser irradiation is used to depolymerise surplus encapsulation which is in the form of a thin film extending from an encapsulation of the device. Where the surplus is a thin sheet lying for example over a heatsink or over and between leads the laser irradiation may also vaporise the surplus without damage to underlying parts of the device. Where the surplus is present as a surface layer at an external surface of the encapsulation, the laser depolymerised surplus may be removed by dry grinding with a relatively soft grinding medium. Laser radiation from a CO2 laser operating at 10.6 microns may be used at a power density between 4.5 and 22.5MWcm<-2>. The device may be a semiconductor device.

Title: System for compensation of capacitive and active earth currents
Inventor: HRYNKIEWICZ JAROSLAW
IPC: H02H9/08
Filed: 1985-11-20
Abstract: A system for compensation of capacitive and active current components in a 3-phase a.c. mains network includes an induction unit 1 connected between an artificial neutral point 2 of the mains supply and earth. The induction unit 1 includes a work winding, two auxiliary windings and means for adjusting the inductance of the work winding. In the event that one phase of the network fails, a fault signal is passed from control-measurement means 5 to a control unit 4. The control unit generates control signals to control the inductance adjustment means so as to vary the inductance of the work coil to compensate the capacitive current component, and to control an impedance converter amplifier 3 which acts on the work winding via the auxiliary windings to compensate the active current component. Compensation of the current components is achieved by bringing the inductance of the induction unit to resonance with the mains capacitance. <IMAGE>
