A method of forming a wick using a mandrel is disclosed. The method includes positioning a wick mesh about the mandrel, positioning a sheath about the mandrel and the wick mesh, coupling a first fitting to the mandrel, wherein the first fitting comprises an adapter configured to couple with a source of pressure, and pressurizing the mandrel with the source of pressure to hydraulically expand the mandrel such that that mandrel compresses the wick mesh against the sheath and forms the wick.

The present application particularly relates to connection tools include ring compression molds, clamping mechanisms, and clamping pipe connection tools. The ring compression mold is used to fit with calipers of the connection tool, including: a fixed mold and a movable mold group, which contains movable molds arranged on both sides of the fixed mold. A crimping hole for a crimping target to pass through is formed in the enclosure between the fixed mold and the movable mold group, a spherical groove for the ring mold to fit with the calipers is provided on the end of the movable mold away from the fixed mold, and the edge of the ring mold spherical groove is provided with a ring mold clearance groove and ring mold convex portions located on both sides of the ring mold clearance groove.

Various embodiments of a compression collar expander assembly for expanding a tubular compression collar are described. For example, the compression collar expander assembly can include a guide plate, a spindle plate, and a plurality of carriages movably disposed on a top surface of the guide plate. Each of the plurality of carriages can include a body, a guide projecting from the body, and a die set comprising a plurality of dies. Each die can include a base coupled to a corresponding one of the plurality of carriages and a prong upstanding from the base. In some embodiments, a tapered expander is configured to assist with expanding the plurality of dies.

A swage tool comprises a head assembly with a die block holding a lower swage die and a yoke holding an upper swage die. A detachable power unit includes a piston within a cylinder that applies force for vertical movement. The die block, attached to the piston, moves towards the stationary yoke to cause radial compression between the swage dies. The tool includes a mechanism for determining proper swage performance, tool holding mechanisms that improve operator maneuverability, endplates that lock and unlock the swage dies to the tool without themselves being removed from the tool, and a yoke-locking mechanism allowing selective removal of the yoke from the tool.

A press fitting device, components and method provide one or more indicators to provide a visual indication that the fitting has been properly pressed around a pipe and that the correct amount of pressure has been provided to create a permanent seal. In embodiments, an indicator ring is retained within one or more windows of a main body component of the fitting and the indicator ring is expandable upon compression to be visible through the window(s).

A hose crimping tool and holder device includes a holder stand having a base, and two panels extended upwardly from the base for forming a space between the panels, a hand pump set includes a crimper member formed on a hand grip and having a chamber, an arm includes two end portions pivotally attached to two end portions of the crimper member with a pivot axle and a pivot shaft, and a compartment formed in the arm, and a crimper die set engaged with the compartment of the arm and the chamber of the crimper member, and the crimper member is partially engaged with the panels with a pivot pin. The crimper member is engaged between the panels and pivotally mounted to the panels with the pivot pin. A sliding element is slidably engaged in the crimper member and engageable with the crimper die set.

A device and method of radially collapsing a medical device is disclosed. The device is in the form of an improved crimper which is capable of crimping a medical device. The crimper includes without limitation one or more of, a base plate, a stopper, two side plates, two housing plates with a handle, a plurality of jaws, two guide plates, at least one gear ring and a plurality of gear pins. The jaws, when assembled, collectively form an iris opening. The assembly of the crimper has a central opening through which the iris opening can be accessed. The device to be crimped is introduced in the central opening and held within the iris opening. The crimping is achieved by reducing the size of the iris opening (by moving the jaws simultaneously with respect to each other in synchronized manner) which in turn reduces the diameter of the prosthetic device.

Systems and methods for reporting usage of a power tool. The power tool comprises a pair of jaws configured to crimp a workpiece, a piston cylinder configured to actuate at least one of the pair of jaws, and a sensor configured to sense operating characteristics associated with a crimping application. An electronic processor connected to the sensor. The electronic processor is configured to receive, from the sensor, one or more characteristic signals, determine, based on the one or more characteristic signals, a first operating characteristic of the power tool, and determine, based on the one or more characteristic signals, a second operating characteristic of the power tool. The electronic processor is configured to determine the crimping application of the power tool based on the first operating characteristic and the second operating characteristic and generate a report indicating the crimping application performed by the power tool.
