Abstract: Novel protease variants derived from the DNA sequences of naturally-occurring or recombinant non-human proteases are disclosed. The variant proteases, in general, are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant protease to generate the substitution of a plurality of amino acid residues in the amino acid sequence of a precursor protease. Such variant proteases have properties which are different from those of the precursor protease, such as altered wash performance. The substituted amino acid residue equivalent to positions 7, 23, 26, 28, 29, 30, 31, 47, 66, 69, 73, 82, 85, 88, 90, 92, 93, 105, 113, 139, 148, 149, 150, 151, 178, 200, 201, 231, 233, 267 and/or 273 of Bacillus amyloliquefaciens subtilisin.

Abstract: The present invention provides an electrical isolation apparatus having independently controllable contactors. The isolation apparatus includes a contactor for each phase or pole of an electrical device as well as each phase or pole of a load. The electrical isolation apparatus is designed to provide galvanic electrical isolation to and protect a starter or drive such that the load side contactors are housed within a single contactor assembly and the line side contacts are housed within a single contactor assembly. Each contactor is constructed so that each includes multiple contact assemblies that may be independently controlled to open and close. Moreover, the contactors within a single contactor assembly or housing can be independently controlled so that the contacts of one contactor can be opened without opening the contacts of the other contactors in the contactor assembly. Additionally, the contactors are constructed and controlled such that a single line side contactor and a single load contactor open simultaneously when an open circuit condition is desired.
