A pipe adapter includes a first tubular element, a second tubular element, and an annular securing member disposed around and fixed to a second portion of the first tubular element. The annular securing member has a flange portion that contacts and secures the second tubular element axially relative to the first tubular element while also allowing the second tubular element to rotate relative to the first tubular element and the annular securing member. An annular sealing member is located around the first portion of the second tubular element to provide an axial seal along the adapter.

A coupling permitting rotation of pipe elements about their longitudinal axes includes a first ring attachable to a first of the pipe elements. The first ring has a first collar projecting outwardly therefrom and defining a low friction bearing surface. A housing defines a bore therethrough surrounding a longitudinal axis arranged coaxially with the bore. The housing has a first end and a second end oppositely disposed from one another. The first end is adapted to receive the first ring coaxially within the bore. The housing comprises a first shoulder and a first channel. When the first ring is received within the bore at the first end, the first collar is positionable between the first shoulder and the first channel. The bearing surface is engageable with the first shoulder. Engagement between the bearing surface and the first shoulder allows rotation of the first ring with respect to the housing.

A waste collection device and a docking device are provided for collecting waste generated in a medical process. The waste collection device is docked with the docking device to discharge the waste. The waste collection device comprises a portable cart; at least one waste collection container mounted to the portable cart and configured to store waste generated in a medical process; a mating bracket mounted to the portable cart and configured to mate with the docking device; two collection end connectors attached to the mating bracket and connected to the at least one waste collection container; and two floating sleeve heads mounted to the mating bracket and correspondingly sleeved on the two collection end connectors. The floating sleeve heads can guide docking end connectors to connect with the corresponding collection end connectors so that said connectors are accurately connected, and the invention has a simple structure and low manufacture cost.

A faucet includes a base configured to attach to a support, an outlet for dispensing a fluid, an articulable spout including a plurality of segments operatively coupled together sequentially between the base and the outlet and configured to rotate relative to one another to transition the articulable spout between a first position and a second position, and an actuator operatively coupled to at least two segments of the plurality of segments and configured to rotate the at least two segments in opposite rotational directions.

An embodiment of this invention provides a swivel joint for a working machine that makes it easy to install a device for detecting rotation angle and is able to suppress the increase of the size due to the installation of the device. An embodiment of the present invention includes the swivel joint that includes an outer body being secured on one of the lower traveling body and the upper swiveling body and having a blocking surface on one end; an inner body being secured on another of the lower traveling body and the upper swiveling body and being relatively and rotatably fitted in the outer body while opposing to the blocking surface at one end n in the manner of making a space; a pilot oil passage being formed on rotational center line CL of the inner body for distributing pilot oil; a rod being inserted into the pilot oil passage and being secured on one of the outer body and the inner body; and a rotation angle sensor being secured on the other end of the outer body and the inner body for detecting a rotation angle of the rod.

A manifold alignment system includes a first modular skid with a first frame, the first frame having a first end with at least one first sloped surface, a second modular skid with a second frame, the second frame having a second end with at least one second sloped surface, wherein the at least one first sloped surface mates with the at least one second sloped surface, and a removably mounted hydraulic mechanism attached to the first end of the first skid and the second end of the second skid.

A hose coupling device is disclosed. The device is an improved hose coupling that allows the hose to move more freely than a traditional coupling. The hose coupling device comprises a sleeve component with a female hose thread on one end and a male hose thread on the other end. The sleeve component further comprises a bearing above and below an O-ring water seal. The hose coupling component rotates independently from the hand nozzle component and eliminates the twist/kink of the hose when walking around spraying water.

A rotary seal arrangement for use with a central tire inflation system is provided. The rotary seal arrangement comprises a stationary portion, a rotating portion, a first sealing ring, a second sealing ring, and a first bushing portion. The stationary portion defines a first air passage therethrough and the rotating portion defines a second air passage therethrough. The first sealing ring and the second sealing ring are each disposed on one of the rotating portion and the stationary portion. The first bushing is disposed on one of the rotating portion and the stationary portion. The first bushing is in dynamic sealing engagement with the first sealing ring. The stationary portion, the rotating portion, the first sealing ring, and the second sealing ring form a sealed cavity that facilitates fluid communication between the first air passage and the second air passage.

The invention relates to a swivel arrangement for a carousel filler having a rotating tank (2) and a product pipe (4) for transporting product into the rotating tank, is provided. The swivel arrangement comprises a tank connecting part (6) arranged to rotate with the rotating tank, a product pipe connecting part (5) arranged to at least partly surround the tank connecting part and an intermediate part (7) arranged between the tank connecting part and the product pipe connecting part, the intermediate part being arranged to rotate with a rotational speed different from a rotational speed of the tank connecting part. The invention also relates to a carousel filler comprising such a swivel arrangement.

A rotary joint capable of measuring a rotation angle with high accuracy is provided. The rotary joint includes: a flange; a rotor whose one end is connected with the flange and that has a tubular shape; a shaft whose outer periphery is connected with an inner periphery of the rotor so that the shaft is rotatable about a central axis of the rotor as a rotation axis; and a rod whose one end is connected with the flange and that is provided in an opening so as to extend from one end side of the shaft along the central axis; an angle measurement unit that is connected with the opening so as to extend from another end side of the shaft to another end of the rod and that measures a rotation angle between the rod and the shaft with the central axis serving as the rotation axis; and a shield member that is formed in a cup shape, an outer periphery of the shield member being connected with the opening so that the shield member is rotatable along the central axis, the other end of the rod being connected with an inner periphery of the shield member, and the shield member acting as a shield between the rod and the angle measurement unit in the opening.
