Abstract: This invention relates to an assembly composed of a plurality of generally parallel corrugated contact sheets. The corrugations form alternating apices in the sheets. The apices are connected by angled walls. The corrugations in each sheet are substantially parallel and disposed at an oblique angle to an edge of the sheet. Adjacent sheets are oriented such that the corrugations of one sheet cross the corrugations of an adjacent sheet at intersections of the apices. The sheets have generally planar positioner pads positioned at least at some of the intersections of the apices of the corrugations of adjacent. The apices have indented portions between each positioner pad.

Abstract: Plastic linings in the form of synthetic polymeric plastic resiliently flexible sheets are disclosed having matingly engagable connector structures along their opposing edges to permit mated engagement of adjoining sheets to form a continuous lining. The sheets have a uniform transverse cross section which extends from one end of the sheet to an opposing end of the sheet to permit extrusion of each sheet. Y-shaped engagement members are preferably provided to better secure the sheet to the surface of a concrete body of a concrete structural element being lined with the sheet. The matingly engaged connectors further provide a compression joint between mated, adjoining sheets. The sheets may also be bonded together along the joints to provide a fluid-impervious seal between the mated sheets. L-shaped synthetic polymeric plastic end members are further bonded to the sheet at corners of the concrete body where the sheets end to provide smooth, protected surfaces for coupling elements together.

Abstract: The present invention is directed to a truck bed liner having a front end and a rear end, the liner comprising a floor, opposed side walls having side edges joining the floor, a front wall having side edges joining the side walls and a lower edge joining the floor, and support elements associated with the side walls adapted to support a shelf member extending between the side walls within the liner above the floor. More specifically, the support elements comprise side wall portions extending within the liner between the side walls and having a horizontal upper surface adapted to support the shelf member. Preferably, retainers, which may be in the form of recesses formed in the side wall portions, are provided for retaining transverse shelf support members extending from one side wall to the other side wall.

Abstract: Improved gas liquid contact sheets and contact bodies are disclosed comprising a plurality of parallel and generally vertical corrugated contact sheets, wherein the corrugations form alternating apices in the sheets, the corrugations being disposed at an angle to the horizontal and wherein the corrugations are substantially parallel and adjacent sheets are oriented such that corrugations of one sheet cross the corrugations of an adjacent sheet at intersections of the apices, the improvement comprising positioner pads positioned in apices of the corrugations of the contact sheets, such that at least about eighty percent of the intersections of adjacent sheets contain abutting pairs of the positioner pads. In addition, contact bodies in which adjacent sheet corrugations intersect proximate the edges of the contact sheets are provided.

Abstract: The present invention comprises an apparatus for removing mist from a mist laden air stream comprising:a. a plurality of stacked blades mounted in blade holding means, each blade having an inlet side and an outlet side and being stacked to allow the mist laden air stream to flow between the blades;b. impact means disposed on a surface of each blade against which the mist and air impacts for removing mist from the air stream; andc. pressure drop reducing means disposed on the outlet side of each blade for reducing the pressure drop of the air stream across the blades.The impact means is an integrally formed curved arch against which the mist laden air impacts to form drops and down which the drops flow. The pressure drop reducing means is an angled lip which extends along the length of the blade from the outlet edge of the blade.

Abstract: The invention relates to a method and apparatus for introducing a catalyst into a fuel mixture. The method includes placing water in a container; passing air through the water to ionize at least a portion of the air molecules wherein at least a major portion of the air ions have a negative charge; and introducing the ionized air into a fuel mixture. In this manner, the efficiency of the combustion of the fuel mixture is increased. The apparatus includes a container for holding water, a manifold mechanism for passing air through the water in the container in a number of streams of small bubbles and means for removing substantially all mist from the ionized air before the ionized air is removed from the container. Means are provided for removing the ionized air from the container after the air has passed through the water and for then introducing the ionized air into a fuel mixture.
