Title: Polymerisation process for preparation of non-aqueous dispersions of microparticles and coating compositions containing said microparticles
Inventor: BACKHOUSE ALAN JAMES
IPC: C08F2/20
Filed: 1980-12-01
Granted: 1984-05-24
Abstract: A process is described for making sterically stabilised non-aqueous dispersions of composite polymer microparticles, in which (1) monomers including at least one crosslinking monomer are polymerised in an aqueous medium at a temperature at least 10° higher than the glass transition temperature of the polymer to be formed, in the presence of a block or graft copolymer stabilising agent, under conditions such that there is at no time present a separate monomer phase, (2) further monomers, not including any crosslinking monomer, are polymerised in the dispersion thus obtained, the presence of a separate monomer phase again being avoided, and (3) the microparticles are transferred from the resulting dispersion into a non-aqueous medium which is a solvent for the non-cross- linked polymer generated in (2). The microparticles are of value for incorporation into coating compositions the main film-forming constituent of which is compatible with the non-cross- linked component of the particles.

Title: Apparatus for projecting a laser beam in a linear pattern
Inventor: OZAKI YASUTO
IPC: G02B17/00
Filed: 1983-11-03
Granted: 1988-03-10
Abstract: The laser beam (2), once spread radially by a convex reflector (4) or by a concave lens, is made to converge linearly by means of a cylindrical-concave reflector (5). The line of light L obtained on an object is a constant and non-flickering one, unlike that obtained by a conventional apparatus which reflects a laser beam by means of a rapidly rotating polygonal-prismatic mirror to give an apparent line of light on an object. Various patterns of lines are obtainable by making the cylindrical-concave reflector (5) have a plurality of cylindrical-concave reflective surfaces curved about different axes. A line on a curved surface is produced by variation of the curvature of the concave reflector along the axis of curvature.

Abstract: Crude oil and gas production wells, which no longer produce oil or gas utilizing conventional primary and secondary means of recovery, can be returned to production by treatment comprising addition of a non-aqueous solution of certain phosphate ester surfactants followed by successive treatment with water or a hydrocarbon. Increased production also can be obtained in low-producing oil and gas wells by similar treatment with certain phosphate ester surfactants. Subsequent to treatment of a producer well, the phosphate ester surfactant is forced into the formation utilizing water or a hydrocarbon and said surfactant is allowed to remain in the producing well, for an effective period of at least 12 hours. Thereafter, pumping and/or conventional fluid drive means are then utilized to recover oil or gas from the subterranean oil or gas formation.
