    Abstract: A fluid-actuated fastening device comprises a housing including a housing body defining a fluid cavity and a fluid port. The fluid port places the fluid cavity in selective communication with an outside fluid source. A telescoping mast assembly includes a mast sleeve. A spindle has longitudinally spaced inner and outer spindle ends separated by a longitudinally oriented spindle body. The spindle body is at least partially located within the mast sleeve for telescoping longitudinal movement with respect thereto to transform the mast assembly between compressed and expanded mast states. At least one disc spring is located substantially within the fluid cavity. Introduction of pressurized fluid into the fluid cavity via the fluid port causes at least one of travel of the disc spring between flexed and relaxed spring states and translational movement of the mast between the compressed and expanded mast states.

    Abstract: A pressure system for expanding one or both of a pair of coaxially mounted rotatable shafts to secure a plurality of tool elements at preselected locations along the length of the shafts; the pressure system uses a rotary union connected to the end of the expandable shaft through which fluid pressure flows to the shaft, a control valve by which fluid pressure may be maintained and then released from the shaft, a reservoir for receiving the fluid from the shaft when it is contracted, and a pressure supply device which supplies the necessary pressure to the fluid to expand the shaft sufficiently to secure the tool elements on the shaft. The pressure system is preferably hydraulic in nature and is normally used in conjunction with a plurality of pairs of coaxially mounted rotatable shafts where each of the pairs of shafts are spaced circumferentially equidistant about a central common axis enabling a selected pair to be rotated into a workpiece engaging position.

    Abstract: A clamping device for an axially moveable plunger shaft as used in electroerosion machine tools where clamping and release must be accomplished without any kind of displacement or distortion of the shaft, clamping being effected by a fixed collet-type clamping sleeve with an exterior taper and a spring-loaded matching female sleeve which takes the form of a moveable hydraulic piston inside a stationary housing. Hydraulic pressure against the female sleeve releases the normally clamped shaft. The clamping sleeve itself has a slightly tapered bore to provide initial clamping close to the sleeve shoulders.

    Abstract: A method of securing a tubular member within an annular cam member for the manufacture of a cam shaft is provided, including the steps of forming a cam member from sintered materials with at least two axially extending grooves being provided in the inner surface of the cam member adjacent the portion of the cam member having the greatest thickness such that a radially projecting ridge is defined between adjacent grooves, fitting the tubular member into the cam member, supplying a working fluid to the interior of the tubular member and applying pressure to the fluid so as to expand the tubular member while maintaining substantially the same wall thickness within the cam member until the ridge bites into the outer surface of the expanding tubular member and becomes tightly engaged therewith. The pressure applied to expand the tubular member is less than that required to fully expand the tubular member along the inner surface of the cam member.

    Abstract: A pipe connection joint comprises two coaxial tubular joint members which are telescopically engaged, one within the other. The outer joint member has a bore, and the inner joint member a through bore, of the same diameter as that of the pipeline with which the joint is to be used. The inner joint member is received in a counterbore in the outer joint member, being an interference fit therein over an interface region to provide both a seal and a friction lock precluding relative axial separation of the joint members under internal working pressure. One of the joint members incorporates an externally connectible duct which leads to the interface region, whereby fluid under pressure can be introduced through the duct to relieve said friction lock.
