A coating apparatus for coating the balloon portion of a balloon catheter is described. The coating apparatus includes a rotatable member in which the catheter portion of the balloon catheter is mounted and fixed, and which causes rotation of the balloon catheter. The apparatus also includes a support member in which the distal tip of the catheter is inserted and free to rotate; and a spray nozzle directing sprayed material on the balloon surface. The inventive configuration of the coating apparatus allows the balloon catheter to be rotated along its axis with insubstantial or no wobble, which significantly improves the quality of the coating applied to the surface of the balloon.

A machine and a process for spraying a section of pipeline with air and water. The machine comprises an enclosure configured to surround a section of pipeline; a frame rotatable about a section of pipeline in the enclosure; rotating means operable to rotate the frame; a water delivery arrangement mounted on the frame and rotatable therewith to spray water around a section of pipeline in the enclosure; and an air delivery arrangement mounted on the frame and rotatable therewith to spray air around a section of pipeline in the enclosure. The machine may be used quenching or jet washing a section of pipeline. Optionally, the machine may comprise a heater arrangement mounted on the frame and rotatable therewith to help dry a section of pipeline after it has been jet washed.

A method for plasma coating an object includes an object profile, having the steps of: a) manufacturing a replaceable shield comprising a jet inlet, a nozzle outlet and a sidewall extending from the jet inlet to the nozzle outlet, wherein the nozzle outlet includes an edge essentially congruent to at least part of the object profile; b) detachably attaching the replaceable shield to a jet outlet of a plasma jet generator; c) placing the object at the nozzle outlet such that the object profile fits closely to the nozzle outlet edge; d) plasma coating the object with a low-temperature, oxygen-free plasma at an operating pressure which is higher than the atmospheric pressure by providing a plasma jet in the shield via the plasma jet generator and injecting coating precursors in the plasma jet in the shield.

Some embodiments of the invention belongs to a technical field of NdFeB magnet processing, and mainly relates to a device and method for improving the coercivity of ring-shaped NdFeB magnet. A layer of heavy rare earth coating is sprayed on the inner and outer surfaces of the ring-shaped NdFeB magnet by the device, and then the ring-shaped NdFeB magnet sprayed with the heavy rare-earth coating is subjected to diffusion treatment to improve the coercivity of the ring-shaped NdFeB magnet. The invention uses heavy rare earth slurry as the diffusion source, combined with spraying technology, can quickly and uniformly cover a layer of heavy rare earth coating on the inner and outer surfaces of the ring-shaped NdFeB magnet, and the coercivity of the ring-shaped NdFeB magnet is improved after heat treatment.

A coating booth (101) for elements to be coated. The coating booth (101) comprises a passage between opposing vertical sides (107a, 107b, 108a, 108b) through which elements to be coated are conveyed. There is an entrance (105) at one end of the passage and an exit (106) at the other end of the passage. The coating booth (101) comprises a conveyor line (102) for supporting said elements to be coated and configured to convey said elements from the entrance (105) to the exit (106) along a straight pathway, and, a suction system. The opposing sides of the channel are symmetrical about the pathway. Sets of spray guns (103a, 104a, 103b, 104b) for spraying coating powder at the elements are positioned symmetrically either side of the straight pathway. The suction system comprises vertical suction inlets (109a, 109b) mounted opposite one another on each opposing vertical side of the passage, the suction system being configured to provide equal amounts of suction through each of the opposing vertical suction inlets (109a, 109b).

A device for coating a fiber includes a fiber receiving arrangement and a coating arrangement which includes an application unit which wets the fiber with a coating agent, and a curing unit arranged downstream of the application unit which optically cures the coating agent. The curing unit includes a lamp which emits at least one light beam which is aimed directly or indirectly at a surface of the fiber. A main radiation direction of the lamp includes a beam angle between the main radiation direction and a longitudinal direction of the fiber of less than 40°. The fiber receiving arrangement and the application unit are movable relative to each other in the longitudinal direction of the fiber via a translational motion arrangement so that a wetting process is implemented substantially along an entire length of the fiber.

A pipe conditioning tool comprising a drive unit to move the tool along a pipe and a work head rotatable about an axis of the pipe to condition a surface of the pipe, the drive unit includes a frame extending to opposite sides of the pipe, the frame having legs extending radially beyond the work head to provide support for the tool upon removal from said pipe.

An Tube Spray Gun for coating an elongated member comprising a handle, a flow trigger, at least one positioner engaging the member and adapted to maintain a spray tip in a desired position relative to the member, a mounting means for releasably engaging the spray tip assembly around the member, a coating supply fluidly connected to the spray tip and a flow activated by the trigger and a spray tip assembly calibrated to provide complete radial coverage of the member, whereby an user engages the positioner placing the apparatus around the member and activates the flow trigger while moving the apparatus along the member to coat the entire radial surface of the member with a single pass.

A link chain cleaning and lubricating device, and lubricants for use therein.
