A simplified drive press system is operable to press fit a pair of first working pieces into a second work piece. The drive press system uses a simplified mechanical arrangement to translate an input torque into movement of a pair of drive arms toward and away from one another. Yokes of differing configurations may be attached to the drive arms to accommodate a variety of different work pieces. A nut runner may be used to supply a drive torque to the gear assembly and provide a controlled input torque and control the movement of the drive arms. An overall reduction may be utilized that balances a desired movement resolution with the desire to detect changes in input torque. The nut runner may be programmable to provide a desired movement of the drive arms while monitoring the input torque to detect when a fully press-fitted condition is realized.

A system to remove a ram packer from a ram block is provided. In one embodiment, the system includes an extraction tool having opposing jaws configured to engage a ram packer installed in a ram block. The system may also include an actuator configured to move the opposing jaws to facilitate separation of the ram packer from the ram block. Additional systems, devices, and methods are also disclosed.

A system for extracting an assembly component from an assembly uses an extractor that applies a gripping force around a perimeter of the assembly component, a coupler that applies an extraction force to the extractor and a tensioner fastened to the coupler that generates the extraction force, the extraction force causing the assembly component to slide out of the assembly. The tensioner applies an extraction force to the extractor which pulls the assembly component from the assembly.

An apparatus is provided for removing a component from a device, where the component includes a cylindrical portion and a shoulder adjacent the cylindrical portion. The apparatus includes a base, a puller and a shaft. The base includes a first mount, a second mount and a bridge extending between and connected to the first mount and the second mount. The first mount and the second mount are each configured to engage with the device. The puller includes a forked flange configured to abut against the shoulder of the component when the cylindrical portion of the component is within a channel of the forked flange. The shaft includes a threaded portion mated with a threaded aperture in the bridge. A distal end portion of the shaft is rotatably connected to the puller.

A radiopaque marker bead can be attached to an endoprosthesis by pressing an end of bead into a through hole formed into the endoprosthesis and allowing the opposite end of the bead to pass through the hole and protrude out of the other end of the hole. Both ends of the bead can then be pressed and flattened so as to frictionally engage both ends of the hole. A support tool having a curved outer surface can be inserted into the endoprosthesis to support the endoprosthesis luminal surface while the bead is being pushed into the hole. The support tool has a depression which allows the opposite end of the bead to protrude out of the hole.

A method of suctioning a gasket main body with a suction jig to separate the gasket main body from a carrier film. The method separates a gasket main body from a carrier film in a gasket including a combination of the gasket main body and the carrier film adhered thereto, where a suction jig is used to separate the carrier film and the gasket main body; the suction jig includes a suction surface at a position facing the carrier film; the suction surface being formed with a suction groove having a shape that corresponds with a planar shape of the gasket main body, the suction groove being formed with a plurality of suction paths across the entire periphery; and the gasket main body is suctioned to the suction groove with the suction force from the suction paths in the suction jig and separated from the carrier film.

A nozzle with changeable press fit and a method for calibrating a nozzle is described. The nozzle may be used in a nozzle/flapper type servovalve. The method comprises the steps of providing a nozzle within a cylindrical body defining a cylindrical bore, the nozzle having a tubular shape with an outer cylindrical surface and an inner radial surface., the method further comprises the steps of positioning a first, tubular locking member within the nozzle, and axially moving the first, tubular locking member within the nozzle. The first tubular locking member is configured to cause the nozzle to become positionally fixed at a selected position within the bore in response to the first, tubular locking member being axially moved relative to the nozzle. A nozzle positioning system is also described herein.
