Abstract:
Process for coating hollow objects exhibiting an opening, and beverage cans in particular, in which the hollow objects are immersed completely and with the opening downward in a paint-filled submersion bath, the openings being moved into the vicinity of nozzles for the paint, which are located underneath the surface of the liquid in the submersion bath and which at least partially displace the air trapped in the hollow objects immersed in the submersion bath by means of streams of paint discharging from the nozzles. With this process hollow objects can be painted uniformly inside and outside in one step without its being necessary to turn them either to fill them with paint when immersed in the submersion bath or to drain them after their being lifted out of the bath.
Abstract:
A powder coating apparatus and method are provided for feeding fine powdered coating material such as thermoplastic type material to a succession of discrete articles passing by the apparatus. The invention also provides a powder feed system that deposits an excess of powdered coating material than that required to form the coating and provides for recirculation of the powder not ultimately used to form the coating back to the powder feeding apparatus.
Abstract:
An apparatus for the sizing of a shaped extended element having a longitudinal axis and including lateral surfaces extending substantially parallel to the axis. The apparatus includes a wheel rotatable about an axis. The wheel includes at least one planar ring-shaped surface extending perpendicular to the axis of the wheel and centered on the surface. The ring-shaped surface cooperates with the lateral surface of the shaped elongated element during a displacement of the wheel relative to the element along an axis parallel to the longitudinal axis of the element. A coating device is adapted to deposit, at least on the outer circumference of the wheel a sufficient amount of glue for allowing a sizing of the lateral surface of the shaped element.

Abstract:
This invention relates to apparatus for applying color to the bore of perforations in various materials and more particularly to a device for coloring the buckle holes in belts usually made of leather or similar material. More particularly the device comprises a driven spindle rotatably mounted in a base having one or more recesses or grooves for holding a coloring wax which is applied to the bore of an object such as a strip of leather to which the coloring material is applied so that the bore of the hole, which may be in a belt, has the same appearance as the dye applied to the exterior of the belt. A variety of wax indentations is described as well as the use of a multiple spindle device.
Abstract:
A rotary member having a discharge orifice for dispensing an annular bead of puttylike material upon rotation; the rotary member is mounted for reciprocal movement into and out of a retainer thereby closing and opening the orifice. A material receiving recess in the rotary member is connected to the orifice by a transfer passage. The recess is connected to a supply of material which fills it when the orifice is positioned inside the retainer. It is disconnected from the supply when the orifice is outside the retainer for dispensing at which time any material contained in the recess flows through the transfer passage and is dispensed at the orifice upon rotation of the rotary member.
Abstract:
The invention relates to a method for producing a substrate (1) for an exhaust gas aftertreatment device, having the following steps:
applying (S1) a coating material (12) on an elastic base (11); dipping or pressing (S2) a surface of the substrate (1), in which inlet openings of through-channels (2) are arranged, through the substrate (1) into the coating material (12); lifting off the coated catalyst element (1); and aftertreating, and in particular drying or calcining (S3), the coating material (12) on the coated substrate (1).
Abstract:
An apparatus and methods for applying an inner coating to a wellbore screen are described. The apparatus comprises a support for the wellbore screen, an elongate injector for injecting coating material into the inner bore of the wellbore screen, and a driver for positioning the elongate injector into the inner bore and moving the elongate injector through the inner bore to introduce coating material to the inner bore. The elongate injector has a supported end, a distal end, and a coating material delivery line extending through the elongate injector from a coating material supply to a port at the distal end.
