Abstract: A method of powder coating the inside of tubular goods, such as oilfield pipe and the like, by connecting one end of the pipe to a means for producing a flow of compressible gases therethrough. The other end of the pipe is open to atmospheric pressure. A valve means is connected for controlling the flow of air through the container which holds a single charge of plastic powder. The charge of powdered plastic is isolated upstream of the pipe inlet. The charge is of sufficient size to coat the entire inside peripheral wall surface of the pipe with a substantial uniform coating of plastic. The pipe is heated above the softening temperature of the plastic and axially rotated, so that when the valve is opened, air flows through the container, into the pipe, and establishes a pressure gradient across the entire length of the pipe. This action causes the captured charge of plastic to form a pocket of dispersed plastic particles which is forced to flow through the pipe by the air flow.

Abstract: An automatic dual action apparatus and method for uniformly applying a coating material to the insides of tubular extensions.

Abstract: An aperture plate for an ink jet printer of the continuous stream type is made corrosion resistant to the ink for long printer operating times. The aperture plate is made corrosion resistant by ion implantation, preferably of chromium ions by an ion beam implanting device.

The ion beam density and ion potential are regulated to predetermined ranges to assure effective corrosion protection while preventing overheating which will warp or embrittle the aperture plate.

Abstract: Air is flowed within an annulus fluidly connected to the load end of a pipe to be coated. A premeasured charge of powdered coating material is suspended in an injection airflow and then injected into the annulus. Spiral flow of the air and particles of coating material in the annulus is induced by successively jetting air into the annulus at selected angles to axial flow. The resulting powder cloud has spiral annular movement within the annulus toward the load end of the pipe. An optional conical deflector at the load end deflects the spiral cloud toward the wall of the pipe. The pipe is rotated counter to the tangential or circumferential component of the spiral flow. The nonaxial circumferential component of the spiral flow helps reduce the number of holidays, and insures that the coating material is deposited evenly through the length of the pipe for a uniform coating thickness. The powder cloud is much longer than the pipe. The excess coating material exiting the pipe discharge end is recycled.

Abstract: Spaced apart, hollow, can bodies are formed around a stubhorn and moved past a spray nozzle for spray coating the inside seams of the can bodies. Each can body is received from a conveyor and moved past the spray nozzle at a sufficiently reduced speed to allow the succeeding can body to move into contact with the preceding can body. The spray nozzle continuously sprays the seams of the can bodies, which form in effect a continuous "tube" of can bodies moving past the nozzle. Each can body is conveyed away from the coating station at a speed preferably corresponding to the input conveyor speed so that the spacing between the can bodies is restored. Conveying apparatus at the coating station is provided with a one-way clutch to accommodate conveyor overrunning when uncoated cans are received and when coated cans are drawn away.

Abstract: In order to apply a strip-shaped powder layer onto the inside of a can body to cover a welding seam of the can body in a controlled manner, the can body is moved in a predetermined direction over a spraying head transporting the powder, due to the kinetic energy imparted thereto by a moving air current, to an elongated opening of the spraying head. This elongated opening flow communicates with a spray chamber of the spraying head and is located opposite the welding seam of the can body. While the can body moves past the spraying head there is formed a strip-shaped powder layer at the welding seam without any cloud formation of the powder in the spray chamber.

Abstract: High speed pipe lining is accomplished by supporting a length of pipe to be lined between spindles in a lathe-type apparatus and rotating the pipe at a speed sufficient to afford a G-force of the order of 10-15 G's. A rather fluid concrete mixture comprising gap-graded sand is introduced into the interior of the rotating pipe using a cantilevered trough. The rotational speed of the pipe is then increased substantially to afford a force of the order of 35-50 G's, and the pipe is subjected to high amplitude axial vibrations for a period of time of the order of one minute or less. The resulting concrete lining is highly compacted, quite dense and hard, and has a smooth surface.

Abstract: The problem of distortion in the shape of the vessel by simultaneous heating and rolling at high temperatures is remedied by adding shape retaining, firing rings to the vessel. Firing rings are rings spacedly attached to the periphery of the vessel to maintain the vessel out of direct contact with the rotating means while the vessel is heated to glass firing temperatures. Usually two rings are used, however, more than two may be utilized if desired. The rings extend a sufficient distance from the vessel side so that distortion of the vessel during glassing and rolling is prevented. Typically, the rings extend outward from the vessel wall a distance of from about 2 inches to about 18 inches and, more preferably, from about 4 inches to about 12 inches. The firing rings are loose fitted, or mounted, over the vessel exterior and preferably are positioned near or at the knuckle radius or radii of the vessel.

Abstract: An apparatus and method for metalizing the interior of pipes or tubes is disclosed. The base metal pipe or tube to be internally metalized is moved axially while simultaneously being rotated at a relatively high rpm. A first pre-heat means, preferably an induction heating means, heats a portion of the pipe and its interior to a first elevated temperature, and particles of the metalizing material are deposited into the interior of the pipe to be heated to said first elevated temperature. The rotation of the pipe distributes the fluidized particles into laminae which, under the further influence of centrifugal forces, automatically distributes the semi-fluidized particles effectively. The fluidized metalizing material is bonded together and to the body substrate by application of a second induction heat at a higher heat level or temperature at which bonding occurs between the laminae of metalizing material and between the metalizing material and the base material of the tube or pipe.

Abstract: Certain glycerides are effective flow-promoting agents in powdered acrylic coating formulations. As a powdered acrylic resin coating material is applied by electrostatic sprayer means to a substrate, a rough layer of discrete particles is formed. To produce a commercially acceptable coating, this layer must be fused into a continuous film and induced to flow into a smooth, glossy finish. The subject glycerides, which may be acetylated, promote such flow and produce a surface finish equivalent to that of the conventional acrylic paints which employ an organic solvent vehicle.
