Abstract:
A surface treatment device for applying a surface treatment to an inner surface of a hollow engine shaft includes a supply of a surface treatment agent and an elongated rod extending from a proximal end to a distal end. The elongated rod has an inner passage extending from the proximal end to the distal end. The proximal end has an inlet fluidly coupled to the supply of the surface treatment agent. The inner passage terminates at an outlet at the distal end. The elongated rod is insertable inside the hollow engine shaft. An applicator is disposed at the distal end of the elongated rod adjacent the outlet. The applicator is engageable with the inner surface of the hollow engine shaft for applying the surface treatment agent from the supply of the surface treatment agent to the inner surface of the hollow engine shaft.
Abstract:
A thermoplastic prepreg includes a mat, web, or fabric of fibers and hollow glass microspheres that are positioned atop the mat, web, or fabric of fibers or dispersed therein. The thermoplastic prepreg also includes a thermoplastic polymer that is fully impregnated through the mat, web, or fabric of fibers and the hollow glass microspheres so that the thermoplastic prepreg has a void content of less than 3% by volume of the thermoplastic prepreg. The thermoplastic material is polymerized monomers and oligomers in which greater than 90% by weight of the monomers or oligomers react to form the thermoplastic material.
Abstract:
A system for coating a heat transfer tube for a condenser is disclosed. The system simplifies a process of coating the heat transfer tube, and is able to uniformly coat a plurality of heat transfer tubes. In addition, the system is economically feasible in that coating solution can be reused by collecting and circulating it. Due to super-hydrophobic coating, the size of a droplet condensed on the surfaces of the heat transfer tubes coated by the system can be reduced, and a condensation heat transfer coefficient can be increased.
Abstract:
According to one embodiment, a system for manufacturing a polymethyl methacrylate (PMMA) prepreg includes a mechanism for continuously moving a fabric or mat and a resin application component that applies a methyl methacrylate (MMA) resin to the fabric or mat. The system also includes a press mechanism that presses the fabric or mat during the continuous movement subsequent to the application of the MMA resin to ensure that the MMA resin fully saturates the fabric or mat. The system further includes a curing oven through which the fabric or mat is continuously moved. The curing oven is maintained at a temperature of between 40° C. and 100° C. to polymerize the MMA resin and thereby form PMMA so that upon exiting the curing oven, the fabric or mat is fully impregnated with PMMA.
Abstract:
One embodiment of the disclosure relates to a fiber coating apparatus having a fiber entrance opening, a conical section with walls tapered at half angles between 2 and 25° and height (also referred to as length herein) L1 between 0.25 mm and 2 mm, and a cylindrical land portion of diameter d2 between 0.1 and 0.5 mm and height (length) L2 between 0.05 and 1.25 mm
Abstract:
This invention relates to a method for conducting film coating on the surface of spinning circular workpiece under action of gas pressure, and nozzle utilized in the same. Circular workpiece to be coated is held on a rotating mechanism, and a feedstock loading machine having a nozzle, which is capable of guiding redundant feedstock and overflowing in a specific direction, is set to have a 100 μm gap with the circular workpiece. When the rotating mechanism is rotated, the polymer solution is precoated on the surface of the circular workpiece, and when gas valve is opened, the polymer solution is squeezed to a predetermined thickness by an annular high pressure gas-stream formed on the periphery of a cylinder, produced from the high pressure gas released.
Abstract:
Continuous void-free uniform coatings are formed on filamentous articles by applying a voided or otherwise substantially uneven coating to at least some of the exposed portion of a filamentous article or to a rotating substrate. The filamentous article or substrate is passed through an improvement station containing a plurality of coating-wetted rolls that contact and re-contact the wet coating at different positions along the length of the filamentous article or rotating substrate, wherein the periods of the rolls improve the uniformity of the coating. For coatings applied to a rotating substrate, the uniform wet coating is transferred to the filamentous article. The final coating can be very thin, very uniform and completely or substantially void-free. The coating improvement can be quickly and easily obtained using low cost equipment.
Abstract:
A micro-extruder, comprising a funnel shaped tip piece defining a front aperture, through which wire is drawn, and a front rim, around which extrudate flows, and which has an outer diameter of less than 3.8 mm (150 mils). In addition, a structurally unitary cross-head body has a front aperture and a protruding rim about this front aperture. The funnel shaped tip piece protrudes through the front aperture. Also, a die having a surface that defines an aperture is adapted and positioned to abut the protruding rim and to form a seal against the protruding rim, so that no extrudate may leak out between the surface defining an aperture and the protruding rim.
