Described herein is a technique capable of properly attaching a nozzle to a reaction tube. According to one aspect thereof, there is provided a nozzle installation jig including: a lower plate configured to make contact with a process vessel in a vicinity of a lower end opening of the process vessel in which a nozzle is provided; a frame fixed to the lower plate and extending upward with respect to the lower plate; an upper plate fixed to the frame and provided with a sensor configured to detect a position of the nozzle in the process vessel; and a notification device configured to transmit a notification to an operator according to a detection result of the sensor.

An externally driven conveyor pulley with an integrated thermal control system by which the temperature of the pulley may be controlled whether the pulley is rotating or stationary. The present invention includes a rotary connection device (or plurality of such devices) designed to transfer fluid (liquid or gaseous) or electrical current into/out of a rotating object. The rotary connection device may be a slip-ring for electrical power transfer or a rotary union for liquid transfer, but any device designed to transmit fluid or electricity into a rotating object could be utilized. In one embodiment, temperature control is achieved by transmitting temperature controlled fluids through the pulley via at least one rotary connection device. In an alternative embodiment, temperature control is achieved by transmitting electricity via the rotary connection device to a temperature regulating device in the rotating object. The temperature regulating device could be any electrical heating or cooling unit.

A swivel joint includes a tail section and a body portion that define a passageway therethrough and which can rotate relative to one another. One or more seals and bearings can be disposed between the tail section and the body portion. An electrical conductivity grease fitting can be mounted within a bore hole in the body portion. The electrical conductivity grease fitting can have a lubricant passed therethrough to lubricate the bearings. The electrical conductivity grease fitting has a first portion in electrical communication with the body portion and a second portion that is biased into electrical communication with the tail section to maintain electrical conductivity between the tail section and the body portion.

A pipe adapter includes a first tubular element having a first portion and a second portion axially adjacent the first portion defining a socket. A second tubular element has a first portion and a second portion axially adjacent the first portion, the first portion defining a distal end sized for insertion into the socket and having a radially extending stop. An annular sealing member is located between the first portion of the second tubular element and the second portion of the first tubular element and provides an axial seal therebetween. An annular securing member is rotatably disposed around the first portion of the second tubular element and located within and fixed to the socket. The annular securing member contacts the stop to secure 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 annular securing member.

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 swivel fitting assembly includes a female body providing a first connection end portion, and a male fitting body providing a second connection end portion. The male body and the female body are operatively coupled together to form a fluid passage between the first and second connection end portions, and are configured to permit relative rotation of the bodies relative to each other. A swivel lock mechanism is provided to rotationally lock or release the male body relative to the female body in response to a fluid pressure level in the fitting. The swivel lock includes a collar that transitions to a lock state and holds the male body when fluid pressure is at or above a predefined level. The collar transitions to a release state to enable relative rotation of the bodies when the pressure is below the predefined level.

A radiator includes a main body, two connecting members and two taps. The two connecting members are disposed on opposite sides of the main body. Each of the two taps is rotatably connected to one of the two connecting members, such that the two taps are rotatably disposed on opposite sides of the main body.

A connection arrangement includes a first connection body and a second connection body for forming a pneumatic connection along a connection axis, and a sealing element configured to seal a sealing gap which surrounds the pneumatic connection and which has a longitudinal dimension which extends parallel to the connection axis. A pneumatic flow is able to travel through the first and second connection bodies along the connection axis. The first connection body has a through-hole having a cross section transverse to the connection axis. The second connection body is arranged at least partially in the through-hole. An at least partially circumferential first recess transverse to the connection axis is formed on an outer face of the first connection body extending parallel to the connection axis for receiving the sealing element.

A swivel joint includes a tail section and a body portion that define a passageway therethrough and which can rotate relative to one another. One or more seals and bearings can be disposed between the tail section and the body portion. An electrical conductivity grease fitting can be mounted within a bore hole in the body portion. The electrical conductivity grease fitting can have a lubricant passed therethrough to lubricate the bearings. The electrical conductivity grease fitting has a first portion in electrical communication with the body portion and a second portion that is biased into electrical communication with the tail section to maintain electrical conductivity between the tail section and the body portion.
