Patent ZA-844022-B (ZA)
Title: Selective solid state trip unit associated with a limiting circuit-breaker
Inventor: FRAISSE DIDIER
IPC: H02H3/06
Filed: 1984-05-28
Abstract: An electric current-limiting circuit breaker comprises a pair of separable contacts and a selective solid state trip unit including an actuator cooperating with a latch mechanism for actuating the contacts to a positive open position upon occurrence of an overcurrent condition. The movable contact may also be moved by electrodynamic repulsion towards the open position when the fault current exceeds a predetermined threshold to effect current limiting. A tripping control device has an electronic counter which counts successive opening and closing cycles of the contacts so as to trip mechanism after a given number of cycles. The trip unit further comprises a first time delay tripping circuit, and a second instantaneous tripping circuit which cooperates with the cycle counter so as to ensure either instantaneous tripping or tripping by counting up to a number of cycles preselected on a setting selector.

Title: Coating process
Inventor: HARGREAVES EDWARD
IPC: C03C17/22
Filed: 1985-03-28
Abstract: A process for production of infra red reflecting fluorine containing tin oxide coatings on flat glass comprises directing on to a hot glass surface a suspension in a carrier gas of a finely divided solid volatile inorganic tin (IV) compound, free from carbon-tin bonds, containing both chlorine and fluorine. Especially preferred tin compounds are ammonium hexahalostannates of the formula

Title: Signal processing
Inventor: THURSTON ANDREW
IPC: H04B17/00
Filed: 2000-12-07
Granted: 2005-02-16
Abstract: A filter ( 26 ) is used to average power values of a signal that has been subjected to varying gain. The gain is factorised into two factors, the first being the highest power of 2 within the gain, and the second being a factor which can be multiplied with the first factor to reprodeuce the gain. The power values are divided by the second factor before reaching the filter ( 26 ) and by the first factor after passing through the filter ( 26 ). The signal values already in the filter ( 26 ) are bit-shifted when the exponent in the first changes so that the filter is not disrupted by changes in the gain.
