Abstract: A method is described. The method includes streaming subject data from a subject repository. The method also includes storing a subject length of the subject data. The method further includes executing a hash function on the subject data to produce a subject hash value. The method additionally includes executing the hash function on content data from a content stream based on the subject length to produce a content hash value. The method also includes detecting whether the content data matches the subject data based on the subject hash value and the content hash value. The method further includes reporting a match detection in response to detecting that the content data matches the subject data.

Abstract: A solid denture cleaning composition that when dissolved into water produces an acidic solution for the dissolution and subsequent removal of dental deposits such as tartar and calculus present on contaminated dental prosthesis. The preferred composition contains an effective bleaching agent achieved by the incorporation of a hydrogen peroxide/Plasdone linear vinyl pyrrolidone homopolymer. The resulting formula provides a mild bleaching composition, devoid of per-acid salts, per-acids and chlorinating compounds. The formulation is an effective denture cleaner for stubborn stains and contaminants.

Abstract: The invention relates to a high-temperature stable, one-part, aqueous tooth bleaching composition for contacting a tooth surface. The composition comprises a bleaching agent comprising a high level of a aqueous hydrogen peroxide. The bleaching agent is derived from multiple components within the composition and comprises at least about 15% by weight of the total composition weight. The composition also comprises a bleaching agent stabilizer comprising from about 0.01% to about 1.00% by weight of the total composition weight.

Abstract: An interlocking belt having an elongated female member and an elongated male member extending from its ends. The male and female members extend generally parallel to the lateral edges of the belt and include interlocking complementary dovetail-like projections and notches. A pair of pins extend through the ends of the male and female members for ensuring that the male and female members do not separate as they travel around a pulley. The geometry of the male and female members is such that longitudinal forces extending between the female and male members are borne by the dovetail-like projections and notches and not the pins.
