A rotary pump for a fluid metering system is provided. The rotary pump reciprocates, and is reversed by a signal from a limit switch that is deflected by an actuator arm on a rotating sleeve of the pump system. The rotary pump includes a plunger and optional stopper formed from a two-shot molding process, and including seals overmolded onto the head of the plunger and the head of the optional stopper.

A crank arm for a bicycle may include a body extending along a body axis and having a first body end and a second body end axially spaced apart from the first body end. The insert may also include an insert provided toward the first body end. The insert may include a base portion having a radially outer surface. At least one extension may extend outwardly from the radially outer surface and may be encased within a corresponding recess in the body whereby relative planar movement between the body and the at least one extension in a first plane. The retaining portion may have a retaining portion width measured in the first direction and the retaining width may be greater than the throat width thereby inhibiting relative radial movement between the at least one extension and the recess and preventing radial extraction of the extension from the corresponding recess.

A pipe fitting having a first body and a second body that together at least partially define a fluid flow passage. The first body defines a first portion of the fluid flow passage that extends from a first end of the fluid flow passage to a first internal opening. The second body defines a second portion of the fluid flow passage that extends from a second internal opening to a second end of the fluid flow passage. The first body has a first interface surface that surrounds the first internal opening, the first interface surface having a plurality of anti-rotation grooves. The second body has a second interface surface that surrounds the second internal opening and engages with the first interface surface. The first internal opening is in fluid communication with the second internal opening. The second interface surface has a plurality of anti-rotation fingers that are each received by and engage with a corresponding one of the anti-rotation grooves. Rotation of the second body relative to the first body is resisted by the engagement of the anti-rotation fingers with the anti-rotation grooves.

Tubing systems are described herein. A tubing system can include a tubing assembly, a tubing system component, and a coupling portion. The tubing assembly includes a tubing and a tubing assembly connector coupled to the tubing. The tubing assembly connector defines a connector lumen in fluid communication with the tubing lumen. The tubing assembly connector has a tubing assembly connector elastic modulus greater than the tubing elastic modulus. The tubing system component has a component connector abutted against the tubing assembly connector. The component connector has a component connector elastic modulus greater than the tubing elastic modulus. The coupling portion is overmolded over the tubing assembly connector and the component connector to couple the tubing to the tubing system component.

A manufacturing method contemplates performing vacuum-assisted resin infusion to enclose an elongated core within a cured composite laminate without employing a mold. Not relying upon an external mold enables the process to be efficiently performed for core shapes that are manufactured in low volumes. Typical resin infusion processes utilize flow media that induces bag bridging during vacuum draw in order to provide gaps facilitating resin flow. However, popular flow media also tends to impart directional aggregate forces during vacuum draw, which forces can deform the core since no mold is being used. To avoid unequal and non-dispersed directional forces from deforming the elongated core, a flow media is employed that is configured to disperse and/or reduce such forces. Some such flow media may be knitted so as to allow overlapping strands to slide over one another. Other flow media may ensure that strands are interleaved so that no one strand or group of strands is disposed outwardly of other strands along a substantial length of the strands, thus dispersing bag bridging forces in several directions and avoiding directional aggregate forces. However, such flow media may have inhibited resin flow relative to popular high-flow flow media, and thus new strategies have been developed to ensure appropriate wetting of fibrous reinforcement. An adjustable brace can also be employed to restrain the elongated core from deflecting during application of vacuum and/or resin infusion.

The present disclosure relates to a splitable introducer sheath assembly and the method of manufacturing the same. The splitable introducer sheath assembly includes a sheath tube, a hub portion, and at least two anchors. The sheath tube includes anchor tabs separately extending from the proximal sheath end. In one embodiment. The anchors secure the respective anchor tabs within the respective first and second hub halves. Alternatively, the hub halves may include a base having a first mating surface and a cap having a second mating surface; the anchor tabs extends within the corresponding one of the base with a proximal end of the anchor tab extending beyond the first mating surface; and the first mating surface of the cap is secured to the second mating surface of the base with the proximal end of the corresponding anchor tab secured therebetween.
