There is disclosed a locking sleeve apparatus for securing rotating connection components. In an embodiment, the locking sleeve apparatus comprises: an elongate tube having an inner profile configured to slidingly engage an outer profile of a plurality of rotating connection components; and one or more locking mechanisms positioned internally in the elongate tube near at least one end of the elongate tube; whereby, the plurality of rotating components are mechanically coupled by the elongate tube, and prevented from rotating relative to each other. The inner profile of the elongate tube matches commonly available rotating connection components with multi-sided outer profiles, such as hexagonal nuts. The rotating connection components are configured to rotate in opposite directions relative to each other to tighten or loosen. The one or more locking mechanisms keep the locking sleeve apparatus fitted over the rotating connection components to prevent loosening.

A modified lug press and use thereof is described. The modified lug press includes a press and a cartridge. The press includes a drive which, when activated, crimps a lug, positioned on a die, to a wire. A cartridge holds the given lug and at least one additional lug, and successively aligns the given lug and the at least one next lug for insertion onto the die for crimping by the press. The cartridge includes a left rail, with a track therein, at least one middle rail, and a right rail. Distances between the rails may be adjustable. A drive motor, when activated, successively pushes lugs onto the die. A lug separator permits one lug to be pushed on the die at any given time. A lug placement device inhibit lateral lug movement during wire insertion and crimping operations.

A machine used in tube fabrication, wherein the machine imparts a locating feature near an end of a tube when the tube is located between a clamp die and a bend die of the machine by using a crimp die to form detents and bulges in the tube. The locating feature enables the tube to be located in a larger tube.

The invention relates to a press jaw with a drive press jaw and a press insert which can be coupled and exchanged therewith, a drive press jaw with coupling elements, a press insert with coupling means which can be used as a press jaw insert or as a pressing sling, and system for pressing fittings with pipes with a modular structure with a press jaw, with at least two press inserts with different diameters and a pull insert, wherein the pull insert and the drive press jaw form a pull jaw. This solves the technical problem of further improving the handling and application possibilities of the press jaw, the drive press jaw, the press insert and the system for pressing fittings with pipes.

Embodiments of the invention provide a die retainer for use in a tool. The die retainer can include a ram head, a release button, and a die pin. The ram head includes a die cavity and a pair of lateral sides on opposing sides of the die cavity. The release button can extend through a release button hole formed in the ram head hand include opposing ends that extend past each of the corresponding pair of lateral sides. The die pin extends through a die pin cavity that intersects the release button hole. The die release button can be actuatable from either of the opposing ends to retract the die pin from the die cavity.

Methods of making hose fittings include providing a stem having a fluid conduit, a first end, a second end with a raised shoulder, and a crimp region disposed between the first end and the second end. A swivel tube nut is placed over the stem, and the swivel tube nut is retained on the stem the by the raised shoulder. A ferrule is thereafter placed over the first end of the stem, and the ferrule comprises a partially or fully formed octagonal wrench surface, formed prior to. The ferrule is then crimped, at the octagonal wrench surface, onto the crimp region of the stem.

The disclosure relates to an attachment for a base jaw of a pressing tool for pressing fittings in order to produce pipe connections, comprising an attachment body, a pressing section, formed on the attachment body, to form half of a jaw opening, and comprising a connecting section, formed on the attachment body, for a connection to the base jaw. The technical problem of providing attachments for exchangeable jaws, base jaws and systems which allow an improved use for fittings of different nominal widths is solved in that the pressing section and the connecting section are arranged at a distance from one another. The invention also relates to a base jaw and to a system consisting of at least two pairs of attachments and one pair of base jaws.

A prosthetic valve assembly includes an annular frame having an inner radial surface, an outer radial surface, and defining an inner lumen. The prosthetic valve assembly further includes a leaflet assembly including at least one leaflet having an inner radial surface and an outer radial surface. The at least one leaflet is disposed at least partially within the inner lumen of the annular frame. The prosthetic valve assembly includes a crimping accessory device having a handle and at least one shielding member removably disposed between the outer radial surface of the at least one leaflet and the inner radial surface of the annular frame. The at least one shielding member is configured to reduce physical contact between the at least one leaflet and the inner radial surface of the annular frame.

A radial press is provided, the radial press having a frame structure, a pressing tool, a drive unit, and a press control. The pressing tool comprises a plurality of pressing elements which are disposed uniformly concentrically around a press axis and have pressing surfaces. During the appropriate activation of the drive unit, the pressing elements can be moved synchronously as required towards or away from the press axis. To this end, at least two measured value recorders, which are connected for signal transmission purposes to a comparator associated with the press control, are disposed on the pressing tool at positions spaced apart from one another in the direction of the press axis (A). When the comparative value, generated by the comparator, of the measured values provided by the measured value recorders exceeds a tolerance range stored in the press control, an activation of the signal output unit is triggered.

A power tool including a moveable piston, a motor capable of driving the moveable piston to perform work on a work piece, and a distance sensor configured to sense a movement of the moveable piston. The distance sensor operable to provide sensor information indicative of the movement of the piston. A controller receives the sensor information from the distance sensor. The controller operates the motor to perform work on the work piece based in part on the sensor information that the controller receives from the distance sensor.
