A self-healing reactive target includes a target apparatus and a target holder. The target apparatus is a solid one-piece target apparatus made from a self-healing material. The target holder is configured to hold the one-piece target apparatus. The target holder is made from a tear resistant and self-healing material. Wherein, the solid one-piece target is configured to move about the target holder for providing reactive feedback when shot. Wherein the solid one-piece target apparatus is configured to spin within the target holder for providing instant feedback when shot.

This invention relates to a process for the separation of a metal complex catalyst and any free ligand which may be present, from a homogeneous organic synthesis reaction mixture using sub-nanoporous, chemically stable membranes having discrete pores which allow organic products and by-products to pass through the membrane as permeate while retaining substantially all of the metal complex catalyst and free ligand, if any, as retentate.

Processes are disclosed for the selective hydrolysis of saturated esters, e.g., ethyl propionate, over unsaturated esters, e.g., ethyl acrylate, using enzymes, e.g., lipases. The processes are useful, for example, for removing undesired esters from monomer feeds used in latex polymerization and from the latexes after polymerization. The processes can be used, for example, to treat latexes used in hair fixative compositions to remove unpleasant odors.

Selective hydrolysis of saturated esters over unsaturated esters using

Aqueous acrylic polymer compositions comprising a copolymer of an alkyl acrylate, an alkyl methacrylate and one or more acrylate acids or salts thereof are disclosed. By introducing an alkoxylated surfactant having a surface tension of greater than about 32.2 dynes/cm and less than 48.2 dynes/cm, enhanced freeze-thaw stability can be obtained with the polymer compositions of the present invention. The polymer compositions are compatible in all-aqueous hairspray compositions, as well as those which contain up to about 80 weight percent volatile organic compounds, or more.

Hairsprays and acrylic polymer compositions for use therein

Aqueous, anionic, acrylic polymer compositions comprising a copolymer of an alkyl acrylate, an alkyl methacrylate and one or more acrylate acids or salts thereof is disclosed. By controlling the particle size of the copolymer and introducing a surfactant, enhanced freeze-thaw stability can be obtained with the polymer compositions of the present invention. The polymer compositions are compatible in all-aqueous hairspray compositions, as well as those which contain up to about 80 weight percent volatile organic compounds, or more.

Solid phase change materials, such as CARBOWAX.RTM. polyethylene glycol 8000, are encapsulated in a condensation polymeric shell to provide heat storage material for use in such things as solar heating devices. The phase change material is put into particulate form and then is coated with a reactive monomer, such as ethylene diamine. Then the monomer coated particulates of phase change material are reacted with prepolymers, such as isocyanate-terminated polybutadiene diol, to form elastomeric, condensation polymeric shells. The polymers have elastomeric (flexible) segments which are the prepolymeric portions. The encapsulated phase change material has little or no significant loss of its latent heat of fusion due to its encapsulation.

A viscometer having the ability of automatically periodically determining the viscosity of liquids having periodic gassing and/or foaming phases comprises pressures taps located on the lower side of a nonvertical portion of a conduit through which the sample liquid is pumped. The viscometer further comprises a three-way valve attached to the pump and means for delaying the pumping of liquid into or out of the pump until the three-way valve has adopted its proper orientation.

Viscometer

Described herein is an improved non-aqueous slurry suitable for use as a thickener or viscosifier in oil or gas drilling, fracturing, flow diversion, completion or workover fluids, which slurry comprises a water-soluble cellulose ether polymer, a water-insoluble liquid hydrocarbon, a non-ionic surfactant having an HLB of from about 7 to about 14, and an organo modified clay.
