A solid-state circuit interrupter and arc prevention device (SSI / APD) is disclosed. The SSI / APD is designed to be configured in series with a mechanical circuit breaker and serves to interrupt current flowing through the circuit it is protecting upon a short circuit being detected or if an overload has persisted for an inordinate amount of time. The SSI / APD is capable of detecting and responding to faults in a matter of microseconds and detects and responds to faults on its own, without requiring the mechanical circuit breaker to trip. The mechanical circuit breaker can be optionally tripped after the SSI / APD has opened the circuit. However, the mechanical circuit breaker is tripped only after the SSI / APD has interrupted the circuit, so electrical arcing across the circuit breaker's contacts is avoided. The SSI / APD can also be reset remotely after a fault has been cleared, obviating the need for a person to be present to reset it.

PCT No. PCT / GB96 / 02285 Sec. 371 Date Jun. 10, 1998 Sec. 102(e) Date Jun. 10, 1998 PCT Filed Sep. 18, 1996 PCT Pub. No. WO97 / 10894 PCT Pub. Date Mar. 27, 1997A method of forming a solution of a solid includes the steps of: (1) forming a dispersion which comprises (a) a liquid, (b) the solid dispersed in powder form and (c) a polymeric binder dissolved in the liquid, and (2) mixing the dispersion with the solvent under conditions such that the powder dissolves in the solvent. If a solution prepared by this method is allowed to dry out, the polymeric binder binds the powder and thus suppresses dust formation. The method has particular application to solids which are reactive textile auxiliaries. A dispersion of a solid in powder form in an aqueous liquid contains a major proportion of a low viscosity, water-soluble cellulose ether and a minor proportion of a natural polysaccharide gum.
