Abstract: A ferrofluid composition is defined by fine particles of ferromagnetic material, a liquid carrier for dispersing the ferromagnetic material and a surfactant or surfactants acting as a dispersant. The surfactant is required to have such relation to the carrier that the surfactant has, as its hydrophobic group portion, a structure equivalent to the carrier, and the carrier is selected to be either an alkylpolyphenyl ether oil, an alkylnaphthalene oil or both. By virtue of this structural feature, fine ferromagnetic particles are uniformly and stably dispersed throughout the carrier which has low viscosity and is thermally very stable.

Abstract: The laminated mat of the present invention is suitable for protecting a surface from liquid spills. The mat includes a means for retaining the spills within the laminated mat; a means for channeling the spills throughout the laminated mat; and a means for absorbing the channeled spills. The retained means comprises a sheet of nonporous plastic material. The nonporous sheet is preferably a cushioning, bubble-pack of polyeyhelene and nylon. The channeling means is the bumpy bubble-pack surface. The absorbing means comprises an absorbent sheet, which absorbs the liquid spills that are retained on the nonporous sheet. The nonporous sheet is adhered to the absorbent sheet by a heat bonding process, whereby a polytube heat sealer seals the perimeter of the absorbent sheet to the nonporous sheet. The absorbent material may also be folded several times, and adhered to itself to form an absorbent roll.

Abstract: During a heat treatment in continuous flow of a product mixture consisting of a liquid containing solid particulates, the mixture is heated to a certain desired temperature in one or more heat exchange sections, held at this temperature in a heat-holding section for a certain time, and then cooled to the desired end temperature in one or more heat exchange sections. The residence time of the solid particulates in the heat-holding section is regulated separately and independently of the residence time of the liquid in the heat-holding section, while the solid particulates are constantly flowed round by the liquid. If there are solid particulates of various sizes in the liquid, the residence time of the various size fractions of solid particulates is regulated separately depending on the size of the solid particulates in a particular fraction.
