Abstract: A wakeboard tower assembly includes a base assembly operably supporting a towing assembly between a lowered storage position and a raised in-use position, and a cylinder assembly configured to bias the towing assembly from the lowered storage position toward the raised in-use position, a closed loop fluid circuit that includes a fluid-receiving first chamber including first and second portions and a return passage, and a gas-receiving second chamber including first and second portions in fluid connection with one another, a shaft telescopingly received within the cylinder between retracted and extended positions, and a controllable valve operable between closed and open positions that prevents or allows fluid flow through the return passage and fluid communication between the first and second chambers of the first chamber thereby preventing or allowing the towing assembly from moving between the lowered storage and raised in-use positions.

Abstract: A moving belt conveyor dough press is provided with a pair of vertically opposing platens, at least one of which is movable toward and away from the other. A continuous belt is arranged to pass between the pair of platens, and to carry on an upper surface thereof, a supply of dough masses to be pressed by the platens. At least one of the platens is formed of a cast metal material, and an electrical resistance heating element is cast in place within the at least one platen.

Abstract: A sharpening tool for a veneer knife has a primary stone and a secondary stone driven by a power head. The secondary stone is inclined at an angle to the primary stone corresponding to the angle of the defined faces of the veneer knife cutting edge. Outrigger supports are provided as gauge and guide members for the sharpening tool. The primary stone engages one face of the cutting edge and the secondary stone engages the other face of the cutting edge. The secondary stone is forcibly engaged with the primary stone and is rotatably driven by the primary stone.

Abstract: An improvement to a tubular height adjustable crutch of the type having a foot telescopically slidable within a carrier tube supported between the parallel lower ends of two crutch bows, where the crutch bow ends are right cylinders cut so as to form a right angle corner with the footpiece or carrier tube. A unitary end cap is fitted over the bow ends and the carrier tube for retaining these three members together and to provide an integral bushing for supporting the footpiece against wobbling within the carrier tube. The improvement consists of modifying the cap bottom to provide slanting edges or surfaces for deflecting staircase edges away from possible engagement with the corner defined between the bow ends and the carrier tube, thus preventing consequent injury to the crutch user.
