Abstract: A chute assembly for directing cement from a cement truck is disclosed. The chute comprises an elongate chute of generally u-shaped cross section fabricated from UHMWPe and comprising an upper end and a lower end, a plurality of reinforcing rods arranged along a length of and encased within the UHMWPe, one end of each of the rods adjacent the upper end and another end of each of the rods adjacent the lower end, a pair of u-shaped collars, an upper one of the collars adjacent the upper end and a lower one of the collars adjacent the lower end, and a fastener for securing each of the collars to their respective rod ends. A method of fabrication is also disclosed.

Abstract: The present invention is a method for producing an implant for a corneal pocket assay by introducing a solution into a perforated plate or member, allowing the solution to form pellets, and removing the pellets from the perforations. The present invention also includes a method for performing a corneal pocket assay for testing a putative pharmaceutically active agent into laboratory animals by placing a pellet into the corneal pocket of the laboratory animal, introducing a pharmaceutically active agent into the laboratory animal, and evaluating the pharmaceutical activity of the agent. The present invention also includes pellets and implants for use in a corneal pocket assay produced by the methods of the present invention. The present invention includes a plate for forming an implant for a corneal pocket assay. The present invention also discloses a method of making pills and pills produced thereby.

Abstract: The snow ski is pivotally attached to a snowmobile in order for it to be pivotable about its longitudinal, steering and transversal axes that intersect each other. The ski has a ski sole from which integrally project first and second elongated front lateral keels and an elongated rear central keel. Moreover, rear ski sole depressions are made in the ski sole, at the vicinity of the rear keel. When the ski is in a straight-line position for allowing the snowmobile to move forward in a straight line, it adopts a flat ground-engaging position in which all three keels rest on the ground surface. When the ski is in a turn-carving position for allowing the snowmobile to move forward while turning in a desired direction, the ski is tilted sidewardly with only the central keel and a selected one of the first and second lateral keels resting on the ground, to carve the ground surface in order for the ski to exhibit a self-steering behavior with enhanced gripping effect.
