A connecting device of a liquid cooling module is provided, including a floating connector, a case, and an elastic sheet. The floating connector has a channel configured to let a liquid pass through it. The elastic sheet includes a first extending structure, a second extending structure, and a curved structure. The first extending structure is affixed to the case. The second extending structure is connected to the floating connector. The head end and the tail end of the curved structure are respectively connected to the first extending structure and the second extending structure.

The invention relates generally to natural gas plumbing systems. More specifically, the present invention relates to a plumbing system that is preassembled to a large extent at a manufacturing site prior to shipping to the site of installation. The pre-assembled plumbing system may be used to convey gas to, for example, a fire pit, outdoor gas grill, fire bowl, gas lighting, and fire tables. The pre-assembled plumbing system may be easily installed and may include a flexible gas pipe, a transition riser, and a lead-in assembly. Further, the lead-in assembly may include a swivel joint configured to provide 360 degrees of multi-plane range of motion. The plumbing system may be coiled for storage and then transported to a site. Advantageously, the plumbing system is manufactured and sold as a single pre-assembled unit, thereby facilitating the ease and speed with which the plumbing system can be installed.

A pivotable spray head for connection to a faucet for expelling water is described herein. The spray head includes a spray head top portion having an inlet to receive water from the faucet and a spray head bottom portion having an outlet to expel water. The spray head further includes a pivoting joint mechanism structured to pivot the spray head relative to the faucet about a pivot axis.

A lockable disc brake swivel for use in a drill string is comprised of a tubular swivel housing having a rotatably mounted swivel stem. A disc brake housing is mounted to the swivel housing to encase a radially extending brake disc engaged for rotation with the swivel stem. The disc brake housing also has a disc brake surface that may be selectively engaged with the brake disc to allow or prevent rotation of the swivel stem. The brake piston may be hydraulically or pneumatically activated.

A coupling for fluid-tight connection of two fluid-guiding portions in medical applications. The coupling is an axially lockable quick-connect coupling and comprises a male coupling portion having a continuous first passage and a female coupling portion adapted to be slipped over the male coupling portion and having a continuous second passage. A preferably circumferential radial sealing is provided on the outer periphery of the male coupling portion and/or on the inner periphery of the female coupling portion.

A swivel joint for a construction machine can detect a slewing angle of an upper slewing body and has a high maintainability. The swivel joint includes a body, a stem, a lower cover, and a sensor unit. The sensor unit includes: a rotation angle sensor fixedly attached to an upper end of the stem; and a rod having a distal end provided with a detection target to be detected by the rotation angle sensor and a proximal end fastened to the lower cover. The stem is formed with: a rod insertion hole for receiving the rod to be inserted therethrough; and a stem-side drain oil passage for allowing a drain oil to pass therethrough.

An assembly for connecting a sprinkler to a branch line of a fire suppression system includes a flexible conduit having one end attached to the branch line. The opposite end is attached to the sprinkler. An adapter may be positioned between the conduit and the sprinkler, between the conduit and the branch line, or between the conduit and both the branch line and the sprinkler. The adapter contains a rotating joint which prevents torque from being applied to the conduit. The adapter between the conduit and the sprinkler is received within a bracket. The bracket also receives a cross beam for securing the sprinkler relatively to the branch line.

A connection system (1) is for distributing water in a domestic system. The connection system includes a flexible pipe (2) having at least one end portion for connection to a hydraulic connector. At least one hollow insert (3, 6) axially engages the end portion of the flexible pipe (2). The insert (3, 6) includes a flange-shaped head portion (31, 61) which abuts against the free end of the end portion of the pipe (2). A reinforcement portion (32, 62) extends from the head portion (31, 61) into the end portion of the pipe (2). At least one annular bushing (4) mechanically clamps onto the end portion of the pipe (2). At least one connecting element (5) is fitted onto the end portion of the pipe (2) and includes a device for connection to the hydraulic connector.

A washpipe seal and method includes providing a first sliding mechanical face seal between two seal elements to seal a mud conduit, and a second mechanical face seal between two additional seal elements to define a cavity within a housing of the washpipe between the first and second mechanical face seals and independently from the mud conduit, and in which, during operation, a buffer fluid can be provided.

A multiple port connecting assembly includes a connector body and a fluid isolation adapter. The connector body includes a first fluid passage extending from an adapter port to a first connector port, a second fluid passage extending from the adapter port to a second connector port, a first seat portion disposed between the first fluid passage and the second fluid passage, and a second seat portion disposed between the second fluid passage and an open end portion of the adapter port. The fluid isolation adapter is removably assembled with the adapter port and includes an adapter body defining a first end passage that connects with the first fluid passage, a second end passage that connects with the second fluid passage, a first seal portion sealing against the first seat portion, and a second seal portion sealing against the second seat portion.
