A rotary introducer is provided for introducing a trackable element and/or contaminant onto a flow path of a food-transit system without adjusting a flowrate. The introducer comprises an inlet and an outlet which is communicable with a food-transit conduit; and a pair of rotatable driving/drivable members. In a trackable-element receiving condition, the inlet is open to receive a trackable element in the device cavity, and the outlet is closed by at least one of the driving/drivable member. However, in a discharge condition, the outlet is open such that a trackable-element discharge force is directed radially inwardly through the outlet to discharge the trackable element from the device cavity, thus enabling outlet to close. A food-transit system using the rotary introducer and a method of introducing a trackable element and/or contaminant into food-transit system without adjusting a flowrate of foodstuffs therethrough are also provided.

A self-installing connector for a liquid cooling system of a datacenter component rack system. A datacenter component rack may include manifolds for conveying coolant to or from one or more datacenter electronic components for liquid cooling components of the datacenter electronic component. The self-installing connector provides a fluid connection between the manifold and a liquid cooling system of a datacenter electronic component. The self-installing connector may puncture the manifold at the time the datacenter electronic component is installed. The self-installing connector may form an opening in the manifold and secure one end of the self-installing connector into the opening upon installation of the datacenter electronic component into the datacenter component rack. The self-installing connector can separate at a dripless quick-disconnect coupling for datacenter electronic component maintenance.

An illustrative port assembly includes a male port assembly including a male frame sub-assembly having first and second hinged male frame members rotatable about a first axis, the first and second hinged male frame members being sealable therebetween. A first transfer sleeve is attachable to the male port assembly and is configured to operably connect the male port assembly with a first volume. A female port assembly includes a female frame sub-assembly having first and second hinged female frame members rotatable about a second axis that is coaxially alignable with the first axis. The first and second hinged female frame members are sealable therebetween, and the female frame sub-assembly is sealable with the male frame sub-assembly. A second transfer sleeve is attachable to the female port assembly and is configured to operably connect the female port assembly with a second volume.

A threaded connection includes a first tube having a pin, the pin having pin threads, a circumferential concave outer pin surface, and a pin torque shoulder at a free end, the concave outer pin surface including a pin seal surface and a continuous extension from the pin seal surface to the pin torque shoulder. A second tube has a box, the box has box threads for interacting with the pin threads, a circumferential inner box surface and a box torque shoulder. The inner box surface has a radially inwardly extending box seal surface, the pin seal surface contacts the box seal surface to define a seal. The seal is spaced from the free end when the pin and box torque shoulders contact, the continuous extension continuing from the seal to the pin torque shoulder. A method for making-up a threaded connection is also provided.

Swivel joints comprise a male sub, a female sub, annular races, ball bearings, a replaceable sleeve, and first and second pressure seals. The male sub is rotationally coupled to the female sub at, respective, generally tubular joint ends thereof. A passage extends through the subs. The female joint end and male joint end are rotationally coupled by ball bearings in the annular races. The replaceable sleeve is received in enlarged inner diameter portions of the male joint end and the female joint end. The first pressure seal ring is mounted between the replaceable sleeve and the enlarged diameter portion of the male joint end. The second pressure seal ring is mounted between the replaceable sleeve and the enlarged diameter portion of the female joint end.

A screw-connection system for connecting a long-shaped part with a terminal geometry includes at least a pressure element, a terminal part, and a seal. The pressure element has at least one contact-wall section with a contact surface. The seal has at least one outer radial-seal surface and at least one axial-seal surface. The outer radial-seal surface of the seal interacts in a sealing manner at least partially with the contact surface of the contact-wall section and the axial-seal surface is configured at least for partial sealing with the terminal geometry.

A high torque polymer fittings useful in fluid handling systems. The fittings are especially useful for fluid handling fittings having diameters of one inch or greater. Various embodiments of the fittings disclosed accommodate specialized wrenches for securing the fittings, the wrenches being used to tighten the fittings to a desired torque.

A method of installing at sea a double-walled preheated undersea pipe for transporting fluids, wherein for each new pipe section to be assembled to a pipe that is already installed at sea: the method involves preheating the inner wall unit element inside the outer wall unit element of the new pipe section; assembling the inner wall unit elements of the new pipe section to the inner wall of the pipe that is already installed at sea; assembling the outer wall unit element of the new pipe section to the outer wall of the pipe that is already installed at sea; lowering the new pipe section into the sea; and repeating the above for other new pipe sections to be assembled so as to prestress the pipe while it is being installed at sea.

A liquid transfer connector according to the present disclosure is provided with a plug having a plug body in which a fluid channel is formed, a socket having a socket body in which a fluid channel communicating with the fluid channel is formed when the plug is connected, a plug body housing part provided in the socket body, that receives and houses a distal end of the plug body inserted therein at a time of connection, an O-ring provided in the plug body housing part, that seals an outer periphery of the plug body inserted in the socket body and a cleaning liquid supply hole that supplies a cleaning liquid into the plug body housing part at a position opposite to the distal end of the plug body with respect to the O-ring.
