Abstract:
PURPOSE: A tubular membrane coating apparatus is provided, to allow a coat (membrane) to be coated uniformly, stably and simply on the outer wall and the inner wall of a tubular supporter for improving the quality of a tubular membrane. CONSTITUTION: The apparatus comprises an inner side coat coating part which coats a polymer solution(L) on the inner side of a tubular supporter; and an outer side coat coating part which coats the polymer solution on the outer side of a tubular supporter. The outer side coat coating part comprises a coating block(4) where a tubular supporter passes through the center of the inner accommodating part(4b) containing the polymer solution to allow the polymer solution to be coated on the outer side; a coating guide(5) which is combined with the upper part of the coating block to guide the movement of the tubular supporter and has an injection hole(5a) for injecting the polymer solution into the inner accommodating part at the lower side part of a main wall; and a transport means which transports the tubular supporter vertically through the inside of the coating guide and the coating block. The inner side coat coating part comprises a coating solution injection pipe which is inserted in the tubular supporter to supply the polymer solution; a discharge head which is fixed to the lower part of the coating solution injection pipe to discharge the polymer solution; a coating weight which is connected with the discharge head by a flowing wire and is provided with a cone-shaped solution contact part to induce the polymer solution to the inner main face of the tubular supporter; and a transport means which transport the tubular supporter vertically.
Abstract:
A central tubular defines a central flow passage and spray nozzles along an outer circumference of the central tubular. A first brush pig supports a first end of the central tubular. A second brush pig supports a second end of the tubular. An inflatable balloon is at the second end of the tubular. The inflatable balloon is encircled by the second brush pig. The inflatable balloon is configured to cause a first pressure drop across the balloon when in an inflated state and cause a second pressure drop, less than the first pressure drop, across the balloon when in a deflated state. A flow control system is at the first end of the tubular and is configured to regulate fluid exchange with the tubular and fluid exchange with the inflatable balloon.
Abstract:
A nozzle is configured to discharge a fluid containing a raw material of a catalytic layer to a substrate having first and second end faces and provided with holes each extending from the first end face to the second end face. The nozzle is provided with discharge ports each discharging the fluid toward the first end face of the substrate.
Abstract:
A method for creating a coating onto a conduit is provided. The method includes rotating the conduit while injecting a controlled amount of slurry onto the surface of an inner diameter of the conduit through a nozzle that is retracted from out of the conduit at a controlled speed. The method offers improved reproducibility and repeatability of coating properties in comparison to conventional coating methods.
Abstract:
A coating can be applied to an endolumenal wall of a medical device by positioning an optical fiber within the lumen, providing a photo-activated chemical to contact the endolumenal wall, supplying the optical fiber with radiation capable of activating the chemical within the lumen, and withdrawing the optical fiber from the lumen at a controlled rate while the radiation is being emitted from the optical fiber to activate the chemical in close proximity to the endolumenal wall.

Abstract:
An apparatus is provided according to the present invention for applying a glue bead to a round and non-round container to seal a fitment therein. The container includes a side wall formed about a longitudinal axis and having a closed end and an open end. The apparatus includes a base for holding the container in a fitment applying position and a hot melt glue gun for applying a layer of glue about an interior perimeter of the container to form an adhesion region. The adhesion region extends about the interior of the side walls immediately adjacent the open end thereof. The glue gun is suspended from a rotary bearing assembly which drives the gun about a longitudinal axis of the container as glue is sprayed thereon. A drive pulley, connected to the gun, is remotely driven via a belt and shaft arrangement by an electric motor. The electric motor is controlled to vary the rotational velocity of the gun dependent upon its angular position relative to a starting point to adjust for changes in the radial distance between the gun and the container. The velocity is adjusted such that the spray gun rotates faster when directed towards a portion of the side wall which is close to the spray nozzle and slower when the nozzle is directed toward a portion of the side wall which is remotely located therefrom. By adjusting the rotational velocity of the glue gun, an even bead of glue is applied.
