A sealing fin fixing apparatus can fix a sealing fin to a rotor in a shortened period of time to minimize variations of the pullout strength of the sealing fin. In the sealing fin fixing apparatus that fixes the sealing fin in a sealing groove defined in the outer circumference of the rotor of a rotary machine and includes a headstock for setting a rotor thereon, a Z-stage movable along a Z-axis, an X-stage movable along an X-axis, a tool rest supported on the X-stage, and a caulking tool mounted on the tool rest and including a shank and a pressing roller, while the pressing roller is being held against a caulking wire inserted, together with the sealing fin, in the sealing groove in the rotor that is set on the headstock, the headstock is actuated to rotate the rotor, thereby caulking the caulking wire to fix the sealing fin to the rotor.

A catheter assembly includes a catheter hub defining an interior cavity and a catheter tube extending distally thereof. A rigid actuator is positioned to extend proximally in the interior cavity and support a seal member positioned thereon in the interior cavity. The seal member includes a central membrane, a distal portion, and a proximal portion. An hourglass shaped actuator cavity is formed in the distal portion and receives a barbed end of the actuator. The outer surface of the seal member is in partial circumferential engagement with the catheter hub to define an air path that allows fluid communication between areas of the interior cavity distal and proximal of the seal member. The seal member may be configured for multi-use and include a biasing member that moves the seal member to force the membrane back over the actuator to close the membrane.

A plug for isolating a wellbore. The plug can include a body having a first end and a second end, wherein the body is formed from one or more composite materials and adapted to receive a setting tool through the first end thereof, at least one malleable element disposed about the body, at least one slip disposed about the body, at least one conical member disposed about the body, and one or more shearable threads disposed on an inner surface of the body, adjacent the second end thereof, wherein the one or more shearable threads are adapted to receive at least a portion of a setting tool that enters the body through the first end thereof, and wherein the one or more shearable threads are adapted to engage the setting tool when disposed through the body and adapted to release the setting tool when exposed to a predetermined axial force.

A gasket for preventing the separation of a pipe joint formed between plastic pipes such as pipes manufactured from PVC. The invention provides a restrained pipe joint including a first pipe including a bell with a spigot entryway and a substantially V-shaped annular groove. The annular groove includes a front radial wall and a rear radial wall and a gasket seated in the annular groove. The gasket includes an inner radial face, an opening defined by the inner radial face and an outer radial face with a front radial section located adjacent to the front radial wall of the annular groove and a rear radial section located adjacent to the rear radial wall of the annular groove. A plurality of restraining segments is at least partially embedded in the gasket.

Illustrative Embodiments may provide for an apparatus and method for fitting a first tube to a second tube. The apparatus may have a first section and a second section. The first section and the second section may engage each other to form a spreine. Each section may engage a sleeve. The spreine may encircle the sleeve encircling the first tube. The spreine may include a slider that may receive a force that may move the spreine and the sleeve, engaged within the spreine, and fit the first tube to the second tube. Fitting the first tube to the second tube may include engaging the sleeve with a first O-ring that may encircle a first ferrule in the first tube, and the sleeve simultaneously engaging a second O-ring encircling a second ferrule in a second tube.

A grommet is at least partially comprised of a clear, rigid material is disclosed. The body of the grommet tapers from a proximal end to a distal end, allowing the grommet to be guided into a hole in a post of a handrail system. The interior of the body includes an longitudinal cannulation open to the exterior of the grommet via a helical cut in the surface, allowing for a wire rope to pass through. The grommet can be installed whether or not a wire rope has previously been passed through a railing post.

The present invention relates to a turbine assembly with a basically hollow aerofoil, having at least a cavity with an inner wall and having at least an aperture providing access to the cavity, and at least a first impingement device arrangeable within the cavity. The at least first impingement device is self-locking, resilient and preloadable and has at least one locking element to lock the at least first impingement device in place in the cavity via a force fit between the at least one locking element and the inner wall of the cavity wherein the locking element of the at least first impingement device is embodied as a protrusion extending in an assembled state of the at least first impingement device in the cavity basically perpendicular to a surface of a side wall of the at least first impingement device in a direction towards the inner wall.

The present disclosure relates to various shift selector assemblies having a shift gate with a plurality of indentations corresponding to transmission shift selections. At least one of the indentations is configured to have a flexible depth so as to selectively restrict and accept a pawl pin, thereby mitigating shift position overshoot.

A sealing element for sealing a fluidic connection between a coupling element and a tubular element and thereby providing a sealed flow path through the tubular element and between the coupling element and the tubular element in a longitudinal direction, the sealing element comprising: a recess extending in the longitudinal direction, the recess configured to receive the tubular element; a transverse wall defining an extent of the recess in the longitudinal direction, the transverse wall having a through hole.

A catheter assembly includes a catheter hub defining an interior cavity and a catheter tube extending distally thereof. A rigid actuator is positioned to extend proximally in the interior cavity and support a seal member positioned thereon in the interior cavity. The seal member includes a central membrane, a distal portion, and a proximal portion. An hourglass shaped actuator cavity is formed in the distal portion and receives a barbed end of the actuator. The outer surface of the seal member is in partial circumferential engagement with the catheter hub to define an air path that allows fluid communication between areas of the interior cavity distal and proximal of the seal member. The seal member may be configured for multi-use and include a biasing member that moves the seal member to force the membrane back over the actuator to close the membrane.
