SYSTEM FOR PRODUCING A FULLY IMPREGNATED THERMOPLASTIC PREPREG

According to one embodiment, a system for manufacturing a fully impregnated thermoplastic prepreg includes a mechanism for moving a fabric or mat and a drying mechanism that removes residual moisture from at least one surface of the fabric or mat. The system also includes a resin application mechanism that applies a reactive resin to the fabric or mat and a press mechanism that presses the coated fabric or mat to ensure that the resin fully saturates the fabric or mat. The system further includes a curing oven through which the coated fabric or mat is moved to polymerize the resin and thereby form a thermoplastic polymer so that upon exiting the oven, the fabric or mat is fully impregnated with the thermoplastic polymer. During at least a portion of the process, humidity in the vicinity of the coated fabric or mat is maintained at substantially zero.

Coating apparatus with donor surface, application device, and surplus extraction system

An apparatus is disclosed for coating a surface that is movable relative to the apparatus with a layer of metallic particles or particles having a metal-like appearance and reflectivity, the particles adhering more strongly to the surface than to one another. The apparatus comprises at least one spray head for directly or indirectly applying to the surface a fluid stream within which the particles are suspended, a housing surrounding the spray head(s) and defining an interior plenum for confining the fluid stream, the housing having a rim adjacent the surface that is configured to prevent egress of particles from a sealing gap defined between the rim of the housing and the surface to be coated, and a suction source connected to the housing to extract from the plenum the sprayed fluid and particles suspended in the sprayed fluid. In operation, the suction source extracts substantially all particles that are not in direct contact with the surface, so as to leave only a substantially single particle layer adhering to the surface on exiting the apparatus.

Formation of lining layers in the cathode shells of aluminum electrolytic reduction cells

The invention relates to non-ferrous metallurgy and the electrolytic production of aluminium, and can be used for lining the cathode assembly of an electrolytic cell. The present method consists in 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 the 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 labour costs, healthier working conditions for operatives, and better quality installation of the base of an electrolytic cell.

Recoaters with gas flow management

An additive manufacturing device includes a recoater configured to push powder onto a build platform. The recoater defines an advancing direction for pushing powder. A first baffle is mounted to a first end of a leading edge of the recoater and a second baffle mounted to a second end of the leading edge of the recoater opposite the first end. Each of the first and second baffles includes a base mounted to the recoater, a first wall that extends obliquely ahead of and laterally outward from the base relative to the advancing direction, and a second wall opposite the first wall. The second wall extends obliquely ahead of and laterally inward from the base relative to the advancing direction. A volume is defined between the first and second wall with capacity to collect powder as the recoater advances.

Fiber-containing prepregs and methods and systems of making

Methods of making fiber-containing prepregs are described. The methods may include the steps of providing a plurality of fibers, and applying a reactive resin composition to the plurality of fibers to make a mixture of the plurality of fibers and the resin composition. The reactive resin composition may include at least one of monomers and oligomers capable of polymerizing into a polymerized resin matrix. The mixture may be heated to a polymerization temperature where the monomers, oligomers, or both polymerize to form a fiber-resin amalgam that includes the polymerized resin matrix. The fiber-resin amalgam may be formed into the fiber-containing prepreg. Also described are methods of forming a fiber-reinforced composite that includes the prepreg.

Analytic substrate coating apparatus and method
11692915 · 2023-07-04 ·

An apparatus and method for producing a coated analytic substrate using a compact and portable automated instrument located in the laboratory setting at the point of use which can consistently produce one or a plurality of coated analytic substrates “on demand” for using the analytic substrate immediately after coating, preferably without a step of rinsing the coated analytic substrate before use. The apparatus preferably uses applicator cartridges having a reservoir containing the coating compositions used to form the coatings. Preferably the cartridges are removable and interchangeable to facilitate the production of individual analytic substrates having different coatings or different coating patterns. These coated analytic substrates have superior specimen adhesion characteristics due to the improved quality of the coatings applied by the coating apparatus and due to the quickness with which the coated analytic substrates can be used in the lab after production.
