Abstract:
Tank for depositing a monomolecular film. It comprises a tank having walls and a base and containing a liquid, a barrier defining two areas on the surface of the liquid, means for displacing the barrier on the surface of the liquid, at least one substrate and means for displacing the substrate. The level of the liquid is below the horizontal rim of the tank. The barrier has a break at each of its ends and rests on the edges of the tank. The break defines a narrower portion partly submerged in the liquid. Sealing means are provided between the faces of the narrower portion and the facing walls.
Abstract:
An apparatus for supporting objects of varied shapes for submersion in a liquid, the apparatus comprising a pair of sheets of elastomeric material, each of the sheets having a perimeter, and a frame for supporting at least a portion of the perimeters of the sheets in generally parallel spaced-apart position such that the sheets will hold an object placed therebetween.
Abstract:
A packaged lumber-dipping apparatus comprises a dipping tank of lumber-preserving fluid, a submersible roll case section supported by a hoist mast for lowering a package of lumber into the tank, and infeed and outfeed conveyors. A clamp is mounted on the hoist mast for clamping the package down on the roll case section so that the lumber will not float when submerged in the tank. The infeed conveyor is positioned at an end of the roll case section for feeding a package of lumber lengthwise onto the roll case section. The outfeed conveyor, positioned alongside the tank, receives the package of lumber from the roll case section after dipping. Two tiltable skate roll sections in the roll case section, connected by chains to the clamp, tilt toward the outfeed conveyor when the clamp is raised to unload the package onto the outfeed conveyor after dipping. The roll case section and outfeed conveyor are downwardly inclined lengthwise of the package for draining excess preserving fluid from the lumber back into the tank and into a drip pan underlying the outfeed conveyor, respectively.
Abstract:
A hoist for dipping a package of lumber or other similar work product into a tank of liquid is fabricated basically as a weldment of readily available steel shapes and is of a rugged, reliable design. A vertically movable carriage with forwardly projecting prongs at its lower end receives a package of work product and clamps located above the prongs tightly clamp the package to the carriage during a dipping procedure. The hoist is designed to allow package delivery and removal, to and from the hoist, by a fork lift truck. After placing a package on the hoist the fork lift operator may push a single push button and a control system for the hoist thereafter causes the hoist to automatically go through a full cycle of operation including a immersion period the length of which may be manually adjusted.
Abstract:
An apparatus for treating articles with a solvent, a solvent-containing liquid such as a lacquer, or with solvent vapors, comprises an open treating vessel provided with a device for raising and lowering the articles in the vessel and a heating unit at the bottom of the vessel for heating solvent therein. Around the wall of the vessel, above the bottom thereof, cooling tubes are provided which are connected to the cold branch of a heat pump so as to condense solvent vapors which can collect in a trough below these tubes and can be returned to a compartment of the vessel adjacent the treating compartment. The hot branch of the heat pump is connected via a heat exchanger to a water boiler and heat storage tank and the heater is connected to this boiler by a pump controlled by a control device responsive to the raising and lowering of the articles.
Abstract:
An automatic coating system for making set-up by coating a wax pattern with a refractory material, for use in a lost wax process. The system has a set-up pickup device adapted to pickup the set-ups by one from a set-up pool, a slurry dipping device for dipping the set-up in the slurry of the refractory coating material, a sanding device adapted to deposit sand to the coated set-up and a set-up taking-out device for taking the set-up out of the system. These devices are disposed on a common circle. The system further has aset-up transportation device located at the center of the circle. The transportation device has a plurality of beams extended radially outwardly to positions of the devices on the circle and supported by a shaft which is rotatable and movable up and down. Each beam has an arm which is adapted to hold the set-up. The beams of the transportation device are cyclically moved up and down and rotated back and forth to transport the set-ups from one to the next devices disposed on the circle.
Abstract:
A white cap dipper apparatus for metal fence posts and a method of dipping such posts, wherein the apparatus includes a shuttle car having a tilt frame for removing posts in successive groups from horizontal flow path cables, successively elevating such posts and dipping the same, and then returning the posts to the cables in horizontal position. The car reciprocates back and forth in the dipping zone in such timed relation to the flow path and with such speed that while it creates a gap in the flow path, it does not interrupt the continuity of the flow.
Abstract:
This specification disclosed a method of and apparatus for the application of sealant gasketing or protective material to a can end or to other container members in which a transfer head having a transfer face in the shape of the container member area to be covered by the sealant is covered with sealant and the container member brought into contact with at least the sealant on the transfer face to achieve transfer of the sealant to the container member. In one form the transfer head has a passage opening to the transfer face through which sealant is pumped to cover the transfer face. In another form the transfer head is arranged to be immersed in a tank of sealant to cover the transfer face with sealant.
Abstract:
Method and apparatus for providing a completely encircling coating of an organic polymeric material on a localized region of a glass container. At a coating station, a glass container is rotated through at least 360 degrees. During the rotation, a material application head furnishes fluid organic polymeric material to the surface of the localized region of the glass container which is to be coated. Stop members hold the application head a fixed distance from the localized region and determine the perimeters of the encircling coating and a doctoring edge of the application head helps form a uniform layer or coating of the organic polymeric material completely encircling the localized region.
