摘要： An improved electro-hydraulic clinching system involves generating, through a high potential electric shock, a forceful wave in a fluid such as water, and applying the force of the wave to a sheet of metal. The force of the wave results in deforming the sheet and making the sheet material move through a hole in a second sheet adjacent to the first sheet, thus joining the two sheets. In an alternative implementation, in which neither sheet includes an opening, the force of the wave moves both sheets simultaneously, thereby causing them to join together at the point of impact.

摘要： A balanced essentially vibration-free hand-grippable fluid powered reciprocating blade cutting tool intended primarily for cutting poultry, fish and meat for processing. The tool includes a hollow handle which functions as a motor housing. Fittings are provided for connecting the housing to a source of fluid under pressure and for exhausting fluid from the housing. A reciprocable cutting blade extends forwardly from the handle. A fluid actuated motor within the handle housing includes a pair of aligned piston assemblies of approximately equal weight. The pistons are reciprocable in opposite directions. The cutting blade is secured to one of these pistons. A control valve and fluid flow passages within the housing and associated with the fluid inlet fitting permits fluid to be directed alternately to the inner and outer sides of the pistons for causing the pistons to alternately move toward one another and away from one another. A manually operable trigger controls the flow of fluid into the housing. The angle of the cutting blade relative to the handle is variable to further reduce fatigue and other problems associated with rotation of the wrist, which is a contributing cause of carpal tunnel syndrome.

摘要： A hydraulically operated slip assembly, connectible to a well head or well pipe handling machine and useful to intermittently grip pipe being run into or pulled from the well. The slip assembly has upper and lower plates with passages for pipe. Wedges, carrying unique slip systems, are positioned around the passages and slidably mounted for radial movement between guide plates extending from the upper and lower plates. The wedges are moved radially inward to grip pipe and radially outward to release pipe by a hydraulic cylinder, pivotally mounted aside the lower plate. When actuated to extend, the hydraulic cylinder rotates an inner bearing race and attached camming segments, which move the wedges inwardly to grip pipe. When the cylinder is actuated to contract, the bearing race and camming segments are rotated to pull the wedges outward radially, releasing pipe. The bearing outer race is housed in ring segments between and connecting the slip assembly upper and lower plates. The unique slip systems automatically increase pipe grip, on up or down movement of gripped pipe caused by very small loads. Outward force components, resulting from increased pipe grip, press the outer surfaces of the camming segments into ring segment grooves, developing forces which effectively prevent inadvertent or an purpose actuation of the cylinder from rotating the camming segments to ungrip pipe in the slip assembly.

摘要： A safety device for a drilling rig of the type wherein a drill-carrying cradle is caused to move upwardly or downwardly on a tower by a chain which traverses sprockets at opposite ends of the tower. Shock loads and vibration cause premature failures in the chain when withdrawing a drill string as the cradle is pulled upwardly on the tower. The present invention minimizes shock loads on the chain to minimize the possibility of a chain failure and, at the same time, prevents a fall of the cradle and drill carried thereby if the chain above it should break, this latter function being accomplished with the use of spring-loaded toothed dogs on the cradle which engage the tower and prevent movement of the cradle in the event of a chain failure.

摘要： A torquer/thruster with a hydrostatically actuated chuck assembly having an elastomeric bladder that is fitted about a cylindrical collet into which a flexible roof drill is received. The collet is formed with a series of spaced slits that are disposed in helical paths, portions of the collet between the slits drivingly engage the drill shaft when the bladder is urged against the collet. The collet and bladder are mounted for rotational movement within a piston assembly that is constrained for limited longitudinal movement and fixed against rotational movement. The collet and bladder are moved longitudinally by the piston assembly for applying thrust to the roof drill and are rotatably driven by a rotary driver for applying torque to the roof drill. A pair of driven biased members engage the shaft and provide thrust assistance and retraction of the roof drill.
