An apparatus for connecting two pipes in fluid communication includes a connector body having opposing open ends, with each open end configured for receiving a free end of a pipe, and a mechanical interlock arrangement for preventing or limiting axial movement of the connector body relative to a free end of a pipe when the free end of the pipe is received in an open end of the connector body. A mechanical seal arrangement provides a metal-to-metal seal between a pipe inserted into one of the open ends and the connector body.

A self-sealing fill nipple for a pressure regulator having a fill port, includes a body having a first end having a quick connect fitting, a mid-body region and a threaded region for threadedly engaging the pressure regulator at the fill port. The threaded region extends from about an end of the body toward the mid-body region and is spaced therefrom by a gap. The threaded region has crest and root diameters. The mid-body region includes a tightening element proximal the quick connect fitting and a gap between the tightening element and the threaded region. The gap has a diameter equal to or less than the threaded region root diameter. A combination of a pressure regulator and a self-sealing fill nipple are also disclosed.

A prefabricated part comprises a concrete body that has the form of a pipe section with two pipe ends and a pipe inner side. The pipe inner side is lined at least in some areas by a lining made of plastic material connected to the concrete body, and at least one of the pipe ends is covered at least in some areas by a molded part made of plastic material connected to the concrete body. At least the pipe end, which is covered at least in some areas, has a connecting joint in order to connect the pipe end to a pipe end of a further prefabricated part. The lining consists of a thermoplastic material and the molded part consists of a thermosetting plastic. The lining and the molded part are connected to each other in a sealed manner.

Pipe connector for coupling a first-end pipe and a second-end pipe that includes intermediary attachment connectors for each of the first-end and second-end pipes. The attachment connectors include O-ring slots machined into an external perimeter surface and a movable sleeve that engages with the intermediary attachment connectors to form a seal between the O-ring slots and an internal perimeter surface of the sleeve.

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.

The specification provides a connector for connection between a hose and a device in a fluid line of a fluid circuit, the device comprising a socket for coupling with the connector. The connector comprises a connector body having a device connector plug (250) and comprises a channel formed axially through the connector body between a distal end opening and a proximal end opening, the channel defining a fluid pathway. The connector further comprises a collar (230) arranged at a proximal end of the plug. The plug is configured to be receivable in a socket of the device, the device interface and socket formed for conformity and for secure coupling, the plug comprising an elongated body portion extending from the collar to a distal end of the connector. The plug comprising a seal (280) and a fastener (270) for engaging with the socket. Also provided is a connector and socket pair coding system for providing a coded connection between one or more connectors (200) and one or more device sockets (555) in a fluid circuit.

Electromagnetic interference (EMI) shields and methods for broadband EMI shielding are provided. An EMI shield disposed in a path of electromagnetic radiation blocks a broad range of frequencies (>about 800 MHz to <about 90 GHz) to a shielding efficiency of >to 20 dB, while transmitting wavelengths in a visible range to an average transmission efficiency of >about 85% through the electromagnetic shield. The shield includes a flexible stack comprising a continuous ultrathin metal film comprising silver (Ag) and copper (Cu) and two antireflection dielectric layers disposed on either side of the ultrathin metal film. The shield may also include multiple stacks or an optional graphene layer that may be spaced apart from the flexible stack to achieve radiofrequency (RE) absorption, which provides additional form of EMI shielding. The EMI shield can be made via roll-to-roll sputtering.
