Abstract: Techniques for validating a skill associated with an endorsement are described. In an example embodiment, disclosed is a system comprising a member database and a skill reputation database. The system can receive, from a user device of an endorser, an endorsement of a recipient in a specific skill. Additionally, an endorser value for the endorser can be determined based on a reputation score that is associated with the endorser having the specific skill. Moreover, an overlap value between the endorser and the recipient can be determined based on employment information and educational information of the endorser and the recipient. Furthermore, a quality score can be calculated for the received endorsement based on the endorser value and the overlap value. Subsequently, a user interface can present, on a profile page of the recipient, a validation for the specific skill when the quality score transgresses a predetermined threshold.

Abstract: Techniques for suggesting to a first member an endorsement of a skill possessed by a second member are described. In an example, disclosed is a system that accesses a plurality of skills associated with members from a member database, and accesses a reputation score for each skill of each member from a skill reputation database. Moreover, a subset of skills can be selected based on the reputation scores of the first member. Furthermore, a specific skill in which to endorse the second member can be determined from the subset of skills based on the reputation score of the second member for the specific skill. A quality score for the specific skill is calculated. Subsequently, a user interface can present, on a display of a device of the first member, an endorsement suggestion for the specific skill of the second member when the quality score transgresses a predetermined threshold.

Abstract: A toothbrush having a novel bristle configuration and trim pattern is described. The bristles of the tufts are of varying lengths and are so arranged to form a concave shape resembling the shape of a rubber prophy cup used by dentists and hygienists for polishing teeth. The individual bristles are of varying length and so placed into or mounted in the head to yield tufts having the same concave shape but without the requirement for trimming the bristle ends. In a variant construction, the upper ends of a number of tufts are so contoured, either by trimming or by insertion of various length bristles, that each tuft upper end has a surface which is a portion of a larger concave surface. Thus in one type of arrangement each tuft has its own prophy brush shape at its upper end. In another type of arrangement there is only one prophy brush shape for the entire head, each tuft making its own partial contribution to the single prophy shape.

Abstract: The present invention relates to an improved bristled article and more particularly to an improved toothbrush which has a tuft cavity with a cross-sectional area that decreases such that the tuft cavity is broadest at the open top end and becomes narrower toward the closed bottom end of the tuft cavity. This decrease of the breadth of the tuft cavity results in a greater packing factor in the closed bottom end portion of the cavity than in the open top end and provides higher bristle retention force.

Abstract: The adhesive strength of alumina brackets to acrylic adhesive cements is enhanced by forming an essentially silica coating on the bonding surface of the bracket by the steps of coating said surface with an organosilicon compound such as a silane and then pyrolyzing the organosilicon coating to volatilize the organic components thereof to thereby leave an essentially silica coating.

Abstract: A stain resistant no-mix orthodontic adhesive is disclosed. The adhesive comprises:(a) a first component having a relatively low viscosity and which contains an acrylic or methacrylic diester of ethoxylated bisphenol-A, an acrylic or methacrylic diester of an alkanediol, and benzyl acrylate or methacrylate; and(b) a second component containing a filler and an acrylic or methacrylic diester of ethoxylated bisphenol-A, an acrylic or methacrylic diester of an alkanediol, and benzyl methacrylate or acrylate, said filler being present in an amount within the range of from about 50 to about 80 weight percent of said second component,wherein, one of said first and second components contains a perioxide catalyst and the other of said components contains a tertiary amine activator for said peroxide catalyst.

Abstract: Polyamide and poly(ester-amide) materials are melt-blended to give products having good flexibility at high and low temperatures. The blends are useful for potting, encapsulating, and adhesive applications.

Abstract: This invention provides a graft copolymer of at least one acrylic monomer and chlorinated natural or synthetic rubber, in which at least about 8 percent of the total weight of said graft copolymer is derived from acrylic acid, methacrylic acid, or both. It also provides aqueous dispersions of such graft copolymers and coating compositions containing them.

Abstract: This invention provides deodorized compositions and methods for preparing deodorized compositions comprising at least one odoriferous N-vinyl monomer (e.g., N-vinyl-2-pyrrolidone), and a sufficient deodorizing amount of an alkali metal bisulfite (e.g., NaHSO.sub.3).

Abstract: Dimethyl dichlorovinylcyclopropyl carboxylic acid esters of substituted (alkyl, aryl, halo, amino, etc.) polycyclic alcohols are insecticidal.

Abstract: Radiation curable compositions particularly suitable for use by electron beam are disclosed, comprising a monomer of the formula: ##STR1## in which R.sub.1 is H or alkyl of 1 to 4 carbon atoms;R.sub.2 is alkylene or alkylene ether; andR.sub.3 is alkylcycloalkyl, phenyl or substituted phenyl; anda polyfunctional acrylate of an alkylacrylate curing agent, e.g., the adduct of acrylic acid and a diglycidyl ether of Bisphenol A.

Abstract: 3-Phenoxybenzyl hydroxamates of pyrethroid acids and derivatives are insecticidal.

Abstract: Poly-1,2-epoxy resins, such as diglycidyl ethers of bisphenols, are hydrolyzed at high solids content in organic solvents, such as hexoxyethanol. The hydrolyzed epoxy resins are used in coating formulations (aqueous emulsions or solutions) together with curing agent and, optionally, a catalyst for cross-linking.

Abstract: Thermally cross-linkable emulsifying agents are provided by reacting a polyoxyalkylene glycol with an excess of aminoplast resin sufficient to enable one molecule of the aminoplast resin to be reacted onto each end of the glycol. These agents markedly reduce the surface tension of water and are effective emulsifying agents and, when used in aqueous emulsion coating compositions to emulsify a water insoluble resinous component, the cross-linkable emulsifying agents provide Newtonian flow characteristics and they react when the deposited film is baked to resist extraction from the cured film.

Abstract: A thermally curable aqueous emulsion coating composition is provided in which liquid particles of resinous polyepoxide are emulsified by means of a nonionic surfactant and there is also present an organic solvent soluble carboxyl functional copolymer which is dispersed by means of salt formation utilizing partial neutralization with ammonia or an amine to disperse the copolymer, the combination of nonionic surfactant emulsification of the epoxy resin and partial neutralization of the copolymer carboxyl serving to provide storage stability for this otherwise unstable system.
