Abstract: A hair spray fixative resin comprises a vinyl acetate/alkyl maleate half ester/N-substituted acrylamide terpolymer in a molar ratio of about 1.0 to 0.6-0.8 to 0.08-0.12, which is preferably produced by a suspension or solution polymerization process. Utilizing N-substituted acrylamides in place of isoborneol methacrylates in the terpolymer provides superior holding power over conventional hair fixative resins, at lower cost.

Abstract: An ACM removal assembly is disclosed, including: a nozzle for directing a pressurized fluid against ACM for dislodging the ACM; a fluid supply reservoir connected to the nozzle; a housing which supports the nozzle and capturingly receives spent fluid and dislodged ACM; and a material handing and separating system which includes coarse separating apparatus for coarsely separating the spent fluid from the dislodged ACM and fluid return conduit for returning coarsely separated fluid to the fluid supply reservoir.

Abstract: Non-aerosol pump hair spray compositions herein are applied as a fine spray mist, without nozzle clogging, and dried rapidly, to provide superior hair holding power. The compositions includes a hair fixative resin which is a terpolymer of a vinyl ester, an alkyl maleate half ester, and an acrylate ester of a saturated, hydroxylated bicyclic hydrocarbon, in an amount between 6 and 20% solids, and at a relative viscosity of from 1.10 to below 1.30.

Abstract: Non-aerosol pump hair spray compositions herein are applied as a fine spray mist, without nozzle clogging, and dried rapidly, to provide superior hair holding power. The compositions includes a hair fixative resin which is a copolymer of maleic anhydride and an alkyl vinyl ether, and the ethyl and butyl half-esters thereof, in an amount of between 6 and 20% solids. In suitable embodiments of the invention, the resin is the C.sub.2 -C.sub.4 alkyl half-ester of maleic anhydride and C.sub.1 -C.sub.5 alkyl vinyl ether having a relative viscosity of about 1.20 to 1.35 (1% in ethanol).

Abstract: A microprogrammed control unit of an information processing system having a control sequencer with dual microprogram counters for performing microdiagnostics simultaneously with performing macroprograms. The microdiagnostics comprise background and operability tests, the background tests being interleaved with macroinstruction operations under the control of the two independent microprogam counters. The background tests are run during processor idle time and the operability tests are executed at processor turn-on. The organization of the microdiagnostics into a hierarchical structure allows the use of the same microprogrammed test module for both the background and operability microdiagnostic tests. A prediction/residual coding technique provides fault detection for address and data information within the control sequencer.

Abstract: This invention relates to water soluble heterocyclic cationic graft polymers of cellulose containing units of the structure ##STR1## wherein R is the residue of a cellulosic polymer containing hydroxyl groups; R.sub.1 is hydrogen or methyl; R.sub.2.sup.+ is a quaternized amino amide, a quaternized amino ester or a quaternized 5 or 6 membered heterocyclic ring having up to 2 nitrogen atoms in the ring structure; R.sub.3 is a C.sub.3 to C.sub.8 alkylene group which is optionally substituted with methyl; R.sub.4 is hydrogen or hydroxy; x is an integer having a value of from 1 to 1000 and X is a halide anion.

Abstract: The polymeric sunscreen agents of the present invention comprise interpolymers of(a) an olefinic p-aminobenzoate devoid of hydroxy substitution;(b) N-vinylpyrrolidone;(c) a monomer selected from the group consisting of a vinyl lactam having a number average molecular weight of at least 125, an acrylate or methacrylate or any mixture thereof and optionally(d) acrylic or methacrylic acid.

Abstract: Two independent power supplies for an I.sup.2 L or ISL logic array can be timed to turn on at different times by a simple RC network connected externally of the logic array. The differential timing is utilized to condition or set a bistable device in a predetermined initial desired state, without requiring an additional device terminal pin for that purpose.
