An apparatus for mounting an O-ring to a work piece, including: a plurality of picking components operable to move away from each other to contact and expand the O-ring to pick the O-ring or to move towards each other to release the O-ring; and a guiding component including a frustum portion arranged coaxially with a groove of the work piece, a large end face of the frustum portion arranged adjacent to an end surface of the work piece on which the groove is formed, wherein a diameter of the large end face is substantially same as an inner diameter of the groove, wherein the picking components are operable to release the O-ring onto a tapered surface of the frustum portion so that the O-ring is pushed into the groove along the tapered surface.

The present application discloses an apparatus for mounting an O-ring to a work piece, which includes a body including a plurality of connecting holes for connecting a pressure source to the body; an annular groove formed on the body and adapted to receive the O-ring; and a plurality of air channels formed in the body, the plurality of air channels being in fluid communication with the annular groove and the plurality of connecting holes to provide negative pressure with the pressure source in the annular groove to suck the O-ring in the annular groove, the annular groove is coaxial with a groove formed on a surface of the work piece during the mounting so that the O-ring is dropped into the groove when the pressure source is disconnected from the body or provides positive pressure to the plurality of air channels.

A hammer for installing a gasket into a joint between two pipes, the hammer comprising two opposed substantially rectangular, non-square strike surfaces which are rotationally offset from one another by 90 degrees such that an appropriate substantially rectangular, non-square strike surface may be selected by the user and applied to a gasket by simply rotating the hammer in the user's hands without requiring the user to relocate around the gasket.

The present invention consists of providing a drive shaft damper having a condensed radial size of most of the shaft damper insert along its length for the purposes of lowering the cost of freight and enabling easy installation of the product into the drive shaft. Parts can be inserted into a drive shaft without any radial interference, which then can expand after installation. End portions may have radial interference without compression or with minimal compression to seal the damper.

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.

Apparatus and Methods for fabricating apparatus having a hermetic seal to seal a portion of an apparatus, for example and without limitation, a portion having a MEMS sensor. One such method uses crimping devices to compress a seal in a cavity formed in a housing that includes a MEMS sensor attached to a stress isolator. Under such compression, the seal deforms to hermetically seal surfaces around the inside, outside and bottom of the stress isolator.

A turbine section for a gas turbine engine includes a turbine blade that extends radially outwardly to a radially outer tip and for rotation about an axis of rotation. A support structure is arranged circumferentially about the axis of rotation and has a plurality of attachment members that extend radially inwardly. A blade outer air seal has a plurality of segments mounted in the support structure. Each segment has a first wall circumferentially spaced from a second wall. The first and second walls are joined to a base portion and an outer wall to define a passage that extends axially along the segment.

A method of forming a medical device contact element includes annealing an elongated rod of Ti-15Mo alloy material to form an annealed rod having a Young's Modulus of less than 13.5 Mpsi and an elastic range or strain of at least 0.7%. Then forming a contact ring element from the annealed rod and assembling the contact ring element into a medical device. Contact rings and lead receptacles including the same are also described.

An automated grommet installer and methods of installing a grommet. The installer and methods are capable of seating a grommet in an aperture of a window and facilitating correct alignment of the grommet within the window. Grommets are used to support and seal around a window wiper attached to a window. Typically, grommets are asymmetrical to match the curvature of the window. Embodiments of the described installer maintain grommet orientation while inserting the grommet in the window, quickly and efficiently installing the grommet. In embodiments the installer includes a system for identifying an incorrectly loaded grommet prior to installation and alerting an operator. In other embodiments, the installer includes a positioner that positions the grommet proximate to the window for installation and a gripper having one or more fingers reach through the window aperture, engage the grommet, and draw it into position, seated in the window.

The technology disclosed provides a joint for connecting carrier units together so as to dissipate and absorb axial forces experienced by the carrier units. The joint may be comprised of a joint housing and an elastomeric insert. The housing may be comprised of a body portion and a head portion and the head portion may include an annular flange in which the elastomeric insert is configured to be secured. The elastomeric joint is capable of absorbing and dissipating horizontal, rotational, and vertical forces experienced by the carrier units in non-linear travel along a track.
