An example wire ring is configured as a partial polygon. The partial polygon has a plurality of curved sections interposed between a plurality of straight sections. The wire ring is configured to contact a base of an annular groove of an external component of a valve at multiple contact points. The wire ring is also configured to contact a respective base of a respective annular groove of an internal component of the valve disposed, at least partially, within the external component at multiple respective contact points.

A bag connector system includes a first coupling element, with a self-closing seal and a housing having a fluid inlet port and a fluid outlet port, and a second coupling element, with a housing having a fluid inlet end and a fluid outlet end. The fluid inlet end is configured to displace the self-closing seal when inserted into the fluid outlet port of the first coupling element. A bag connector system optionally includes a locking mechanism to maintain the first coupling element and second coupling element in a coupled state. Uncoupling of the first and second coupling elements results in minimal fluid contamination on the outer surfaces of the coupling elements. The bag connector systems provided herein are included in medical appliances for waste management.

A high-velocity low-pressure cooling system (100), especially suited for data center applications, includes an air coolant loop (102), a non-air coolant loop (104) and a cooler unit (126) for heat transfer between the loops (102 and 104). The air loop (102) is used to chill ambient air that is blown across heat transfer surfaces of equipment mounted in data center racks (110). In this manner, effective cooling is provided using a coolant that is benign in data center environments.

The present invention provides a socket compatible with multiple types of plugs having front end portions varying in length and a pipe connector having this socket. The socket 10 of the present invention mainly includes a base portion 18, first steel balls 22 and second steel balls 24 housed in housing holes of the base portion 18, an outer support portion 26 supporting the first steel balls 22 and the like from the outer side, and an inner support portion 25 supporting the first steel balls 22 and the like from the inner side. The socket 10 includes first housing holes 50 in which the first steel balls 22 are housed and second housing holes 52 in which the second steel balls 24 are housed and which are longer than the first housing holes 50 in an axial direction.

A wedge clamp quick release connector has a main body, a positioning mount, and a quick connecting device. The quick connecting device has a sliding sleeve, at least one wedge clamp and a sleeve spring. The sliding sleeve has a spring recess and a clamp recess. Each wedge clamp is moveably held in the positioning mount, and has a stop portion and a wedge portion. The stop portion has an external surface and a stop plane, and the wedge portion protrudes from a middle of the stop plane and has an internal surface opposite the external surface and two bevels formed on two edges of the internal surface. The sleeve spring is mounted in the spring recess of the sliding sleeve. The engagement between the connector and a corresponding plug is in reliable surface contact by corresponding bevels of each wedge clamp and the plug.
