    Abstract: A fixture for automatically and selectively coating a predetermined area of the inner surface of a hollow body with a liquid, wherein the hollow body has a closed end and an open end with an edge which defines the open end. The fixture is preferably at least partially disposed in a volume of the coating liquid, and comprises a base member, a pressure tube attached to the base member, and in fluid communication with a variable pressure source, and a hollow body support for orienting the hollow body in inverted condition with its open edge partially submerged in the volume of coating liquid. The inverted hollow body thereby provides a closed cavity defined by the closed end of the hollow body and the partially submerged open edge. A preferred embodiment of the fixture further includes a control partition extending upwardly from the base, circumscribing and spaced radially from the pressure tube. The liquid level within the closed cavity formed by the inverted hollow body can hereafter be raised by application of an underpressure to the cavity through the pressure tube, and the uppermost raised level of the liquid is positively limited by the control partition.

    Abstract: A process and apparatus for coating the interior of a fiber-reinforced tube formed of cellulose hydrate in which a tube filled with a coating liquid is passed through a special conveying and pumping device which also serves to replenish the coating liquid. Above the level of the coating liquid, the tube is inflated with a support gas and is gradually flattened. The flattened tube then travels through a metering device made up of wipers in the form of doctor blades or rollers, which retain the major quantity of the coating liquid which is present on the inside surface of the tubing so that a thin, uniform film of the coating liquid is formed. The tubing is thereafter dried to remove the volatile constituents of the coating liquid, and is subsequently wound up.

    Abstract: A process is disclosed for coating the inside surface of a length of tubing comprising the steps of forming at least one loop of tubing with a downwardly inclined portion and an upwardly inclined portion; filling the cavity of the tubing forming the loop with a coating liquid; transporting the tubing along its longitudinal axis in a substantially vertically upward direction to coat the inside of the tubing above the level of the coating liquid with an initial layer of coating liquid; constricting the tubing adjacent to and above the level of the coating liquid along a constriction zone transverse to the longitudinal axis of the tubing, the constriction zone progressively diminishing in width in the direction of travel of the tubing to reduce the thickness of the initial layer and form a thin layer of desired thickness on the inside of the tubing issuing from the constriction zone; filling the cavity of the tubing issuing from the metering device with support gas; and exposing the tubing to heat at a sufficient temperature to fuse the coating layer to the inside of the tubing and form an uninterrupted film of uniform thickness thereon. The coating liquid can comprise an aqueous polymeric dispersion containing at least about 15% by weight of dispersed polymer based on the total weight of the dispersion and preferrably in the range of about 15 to 60% by weight. Also disclosed is an apparatus for carrying out the process of the present invention.

    Abstract: A process of enameling the inside surface of hollow vessels, which have two openings at opposite points. In a hot-water reservoir to be enameled these openings are provided at both ends. One opening is connected to a vacuum pump and the other to a conduit which incorporates a valve and leads to an enamel slip reservoir. In a first step, a vacuum pump is operated to pre-evacuate the interior of the hollow vessel so that air is removed from the pores at the inside surface of the hollow vessel. In this step the valve in the slip conduit remains closed. When the vessel has been preevacuated to about 40 to 80 torrs absolute, the valve is opened so that slip flows suddenly into the hollow vessel and fills the pores while the evacuation is continued and slip is sucked into the hollow vessel until the slip emerges from the opening through which the hollow vessel is being evacuated.
