Abstract: A clock source selector for selecting either a first clock signal A or a second clock signal B in accordance with a switch request signal includes three retiming circuits each consisting of two clocked flip-flops. The switch request signal is first retimed relative to clock A to give a signal P, is then retimed relative to clock B to give a signal Q, and finally is retimed relative to clock A to give a signal R. Selector circuitry operates such that when signal Q is asserted, the second clock signal B is output, when neither signal P nor signal R, as combined by a NOR gate, are asserted, the first clock signal A is output, and at other times a zero level is output. The clock source selector can be used in an integrated circuit to form a glitch-free multiplexer.

Abstract: Protease conjugates such as subtilisin conjugates are provided comprising a protease moiety and one or more addition moieties wherein the protease moiety has a modified amino acid sequence of a parent amino acid sequence. The parent amino acid sequence comprises a first epitope region, a second epitope region and a third epitope region, and the modified amino acid sequence comprises a substitution by a substituting amino acid at one or more positions in one or more of the epitope regions. When a substitution occurs in the first epitope region, the substitution occurs at one or more positions corresponding to positions 70-84 of subtilisin BPN′. When a substitution occurs in the second epitope region, the substitution occurs at one or more positions corresponding to positions 103-126 of subtilisin BPN′. When a substitution occurs in the third epitope region, the substitution occurs at one or more positions corresponding to positions 217-252 of subtilisin BPN′.

Abstract: A wood floor system comprises a plurality of parallel rows (10a, 10b . . . 10z) of floorboards (10) laid end-to-end, and each of the floorboards (10) includes a compression nub (20) extending along a side surface (13) thereof, adjacent the top surface ( ). These compression nubs (20) affirmatively engage an opposing side surface (14) of an adjacent floorboard row (10a), thereby sealing, or isolating, the top surface of the floor from the side surfaces (13, 14) of the floorboard rows (10a, 10b . . . 10z). This uniformly distributes expansion and contraction forces throughout the floor, due to uniform spacing between the floorboard rows (10a, 10b . . . 10z). The isolation of the floorboard upper surface from the side surfaces (13, 14) also prevents undesired downward migration or flow of liquid finishing solution (28), which can have serious adverse affects for a wood floor. The invention reduces the total volume of finishing solution necessary for finishing the floor.

Abstract: The present relates to cleaning compositions comprising a protease enzyme which is a carbonyl variant having an amino acid sequence not found in nature, which is derived by replacement of a plurality of amino acid residues of a precursor carbonyl ydrolase with different amino acids.

Abstract: A device for releasably attaching a towel to clothing of a user. The device includes a towel having an eyelet passing therethrough and a clasp for extending through the eyelet and releasably connecting with an article of clothing of a user. The towel may be removed from engagement with the clasp for cleaning when desired. The attachment of the device to the clothing of the user allows a towel to be readily available to the user for drying the user or cleaning an object.

Abstract: The present invention 10 discloses a clasped towel 10 wherein a towel 11 is attached to a clasp 13 which can be attached by means 30 to an article of clothing 12. A flap 38 is attached to the towel 11 which forms a partial pocket-like enclosure 39 on the towel in which items can be cleaned. An alligator clip-like element 32 is also shown for attaching the present invention 10 to the clothing 12.
