Abstract: A headset adapted for use with a cellular telephone comprises an earphone shaped to fit in the ear of a user, an earphone arm extending from the earphone to an earphone arm pivot end, a support protrusion extending from the earphone arm pivot end to rest under the ear of the user when wearing the headset, a telescoping arm extending from a microphone to a microphone arm pivot end, the microphone arm pivot end pivotally connected to the earphone arm, the telescoping arm having an arcuate shape.

Abstract: Poly(meth)acrylate dispersions, comprised of: (A) 50-90 wt. % methacrylic acid esters; (B) 5-30 wt. % acrylic acid alkyl esters; [lit., “acrylic acid acrylic esters”]; (C) 2-10 wt. % of another functionalized monomer; (D) 2-10 wt. % of a radically polymerizable carboxylic acid or a polycarboxylic acid or a partially esterified polycarboxylic acid; and (E) 0-40 wt. % of a monomer which is copolymerizable with components (A) to (D).

Abstract: Poly(meth)acrylate dispersions, comprised of: (A) 50-90 wt. % methacrylic acid esters; (B) 5-30 wt. % acrylic acid alkyl esters, [lit., “acrylic acid acrylic esters”]; (C) 2-10 wt. % of another functionalized monomer; (D) 2-10 wt. % of a radically polymerizable carboxylic acid or a polycarboxylic acid or a partially esterified polycarboxylic acid; and (E) 0-40 wt. % of a monomer which is copolymerizable with components (A) to (D).

Abstract: A powdery bonding agent for paints which is soluble in pure aliphatic compounds, and which is in the form of powdery polymerizate particles, which consists of, at least on the particle surface, of a copolymerizate formed of: (i) 60 to 95 percent by weight of units of at least one hardening monomer selected from the group consisting of (A) isobutylmethacrylate and (B) cycloalkylmethacrylate; and (ii) 5 to 40 percent by weight of units of at least one aliphatic-substance-solubilizing monomer selected from the group consisting of (C) alkylmethacrylates having 6 to 18 carbon atoms in the alkyl residue, where the units of isobutylmethacrylate account for no more than 60 percent by weight and the units of cycloalkylmethacrylates account for no less than 10 percent by weight, based on, in each case, the weight of the copolymerizate.

Abstract: A method for priming an absorbent mineral or wood substrate to provide a wet-adhering coating, which comprises applying to said substrate a solution, in an organic solvent which has a normal boiling point between 50.degree. C. and 180.degree. C., of a copolymer of monomers of acrylate and methacrylate esters, of styrene and of vinyl esters, and of dialkylaminoalkyl esters of acrylic acid and of methacrylic acid and their corresponding amides, the maximum glass transition temperature of the copolymer being in the range from 20.degree. C. to 80.degree. C. and the reduced viscosity of the copolymer being in the range from 20 to 60 ml/g.

Abstract: A two-step emulsion polymerization method for making an aqueous emulsion of core/shell polymer particles recoverable as a polymer powder by spray drying the emulsion, said polymer being capable of swelling and forming a gel in gasoline, and paints and coating compositions containing gasoline and such a polymer powder as a thickening agent or binder.
