An adhesive dispensing system for applying liquid adhesive to a substrate using different nozzles with the same manifold is disclosed. The adhesive dispensing system includes a manifold having a body, a first clamp configured to engage the body of the manifold, a second clamp configured to engage the body of the manifold, and a nozzle. The first and second clamps secure the nozzle to the body of the manifold. The body of the manifold has a first contact surface that engages the first clamp and a second contact surface that engages the second clamp and the nozzle, where the second contact surface is angularly offset from the first contact surface.

Systems and methods for coating a thin film with a viscous material, such as a liquid, a paste, or an adhesive, at a desired thickness. In such a system, two films move adjacent to one another, optionally in opposite directions, atop two rollers separated by a known gap that defines a coating thickness, with the material being transferred from one film to the other. The rollers may be maintained in their relative positions by springs and/or linear actuators and positioned using linear encoders. In alternative arrangements, the material to be coated could be low viscosity material such as a polymeric solution. Air knives may be provided near the gap to create an air flow that aids in preventing the free flow of low viscosity materials outside the bounds of the film during coating.

A system for manufacturing a thermoplastic prepreg includes a double belt mechanism that is configured to compress a fiber mat, web, or mesh that is passed through the double belt mechanism, a resin applicator that is configured to apply monomers or oligomers to the fiber mat, web, or mesh, and a curing oven that is configured to effect polymerization of the monomers or oligomers and thereby form the thermoplastic polymer as the fiber mat, web, or mesh is moved through the curing oven. The double belt mechanism compresses the fiber mat, web, or mesh and the applied monomers or oligomers as the fiber mat, web, or mesh is passed through the curing oven so that the monomers or oligomers fully saturate the fiber mat, web, or mesh. Upon polymerization of the monomers or oligomers, the fiber mat, web, or mesh is fully impregnated with the thermoplastic polymer.

A window sealing system and method for use in sealing insulating glass units (IGUs) is disclosed herein. The system includes an articulating arm having a plurality of members and arms to allow movement about multiple axes defined by the articulating arm, and a sealant dispensing apparatus releasably couplable to the articulating arm. The sealant dispensing apparatus comprises a pivotable dispensing apparatus for dispensing sealant onto an IGU. The system further including a vision system, coupled to the sealant dispensing apparatus, for monitoring physical properties of the sealant during sealant application.

A slurry scraping mechanism and an applying and scraping device used in an SG abrasive production process includes a scraping master support; a scraper, wherein the scraper is connected with the scraping master support through a suspension component such that the scraper is suspended, and a damping spring is arranged in the suspension component; and a torsion spring adjusting component, wherein the torsion spring adjusting component includes a plurality of torsion springs supported by a torsion spring support shaft, the torsion spring support shaft is fixed to the scraping master support, the torsion spring support shaft is movable up and down relative to the scraping master support, the torsion springs are clamped in a V-shaped plate, an end side of the V-shaped plate is connected with the scraping master support, and a side surface of the V-shaped plate is connected with the scraper.

This disclosure relates to non-ferrous metallurgy and electrolytic production of Aluminium for lining a cathode assembly of an electrolytic cell. The present method includes laying materials while simultaneously distributing same over the surface of a base and levelling them at a height measured from the plane of the top edge of the shell of the cathode assembly of the electrolytic cell by gradually moving a device for installing unformed lining materials along a longitudinal axis of the cathode of the Aluminium electrolytic cell. Said device is configured in the form of a bridge equipped with a mechanical drive for movement. The bridge has guides on which a frame is mounted for vertical movement, said frame having cassettes provided with gates with a mechanical drive. The technical result is reduced labor costs, healthier working conditions for operatives, and better quality installation of the base of an electrolytic cell.

A liquid processing device includes: a nozzle configured to discharge, onto a substrate, a processing liquid supplied from a processing liquid source, the processing liquid being configured to process the substrate; a main flow path which connects the processing liquid source and the nozzle; a filter provided in the main flow path; a branch path branched from the main flow path; a pump provided at an end of the branch path; and a controller configured to output a control signal to perform a first process of sucking the processing liquid supplied from the processing liquid source by the pump to flow the processing liquid into the branch path and then a second process of discharging the processing liquid of a smaller amount than a capacity of the branch path from the pump to the branch path to discharge the processing liquid from the nozzle.
