Abstract: An apparatus and method for automatic thin-layer cell sample slide preparation without requiring human intervention are disclosed. According to one embodiment, a cell sample is measured to derive a cell sample measurement. An estimation of total cellularity of the cell sample is determined based upon the cell sample measurement. A differential volume of diluent is dispensed to the cell sample based upon the estimation of total cellularity of the cell sample to form a cell suspension. In one embodiment, a differential volume of the cell suspension and a differential volume of cell adherent may be combined based upon the estimation of total cellularity of the cell sample to form a cell mixture. A differential volume of the cell suspension or cell mixture (if an adherent is mixed with the cell suspension) is dispensed onto a surface of a sample slide.

Abstract: An improved roof edge ventilation strip serving as a starter strip to underlay the first course of shingling along a roof line. The roof edge ventilation strip comprises a roofing panel which is, in use, at substantially the same angle to the vertical as the roof to which it is attached. The material of the ventilation strip is wavy or corrugated for providing added strength. A horizontal soffit section of the ventilation strip has louvers which add strength to the ventilation strip and permit a ladder to be leaned against the strip outer edge. A vertical fascia section provides for fastening the ventilation strip in abutment to a vertical side of a house or a building. An alternate embodiment comprises a protruding drip edge to insure water run-off away from the house.

Abstract: A pre-cast reinforced concrete catch-basin of larger than conventional catch-basin dimensions includes a solid horizontal bottom wall with solid, hollow, cylindrical side wall upstanding therefrom to about half the height of the catch-basin. The lower half thus forms a sealed, unapertured, undrained, sump receptacle for collecting drain water and silt and allowing sand to settle out. The hollow, cylindrical, upper half contains leaching openings which extend through from the inside to the outside of the wall, from top to bottom, for discharging cleared water to the surrounding, stone-lined, earth without plugging, or clogging, and without polluting nearby wells, brooks, etc.

Abstract: The aqueous thermosetting acrylic enamel is used to finish flexible substrates that are used for automobile and truck bumpers, flexible filler panels located between the bumper and the chassis, flexible fender extensions, flexible exterior trim parts and other impact and energy absorbing parts; the enamel is an aqueous composition containing the following film-forming constituents:A. an acrylic polymer of an alkyl methacrylate having 1-4 carbon atoms in the alkyl group or styrene or a mixture thereof, an alkyl methacrylate having 6-12 carbon atoms in the alkyl group or an alkyl acrylate having 2-12 carbon atoms in the alkyl group, a hydroxy alkyl acrylate or methacrylate or a mixture thereof; and an .alpha.,.beta.-ethylenically unsaturated dicarboxylic acid; andB. a heat reactive condensate such as an alkylated melamine formaldehyde resin;Wherein the film-forming constituents are neutralized with ammonia or an amine to a pH of about 7-10.
