    Abstract: A tow prepreg manufacturing apparatus applies resin to an original tow of reinforcing fibers. The tow prepreg manufacturing apparatus includes an oiling roller, a scraper, a resin reservoir, a tube pump, and a controller. The oiling roller is supplied with resin while rotating at a predetermined rotation speed. The scraper adjusts the shape of the resin supplied onto the oiling roller. The resin reservoir supplies resin to the oiling roller. The tube pump discharges resin to the resin reservoir. The controller controls the tube pump so that the amount of resin held in the resin reservoir remains constant and controls the rotation speed of the oiling roller so that a resin content of a wound tow prepreg becomes equal to a target resin content.

    Abstract: A dry composition comprising 2 to 30 weight percent R2O (wherein R2O is an alkali metal oxide, K2O, Na2O, Li2O or mixtures thereof); 10 to 74 weight percent SiO2; and 23 to 79 weight percent B2O3. Aqueous solutions and/or colloidal suspensions (thus referred to as solution-suspensions) are used to blend to give a liquid-binder which, on drying, contains the composition within the range given above in the R2O—SiO2—B2O3 system. The dry composition is mixed with sufficient H2O to form the solution-suspensions. As described herein H2O may also be present in some additional additive.

    Abstract: A coil coating method for multilayer coating of a continuous metal strip, which is disposed in the strip passage, in which on a flat side of the metal strip, a curable polymer primer is applied by means of a roller application and cured in order to form an electrically insulating primer layer and a curable polymer varnish is applied onto said primer layer by means of roller application and cured in order to form an electrically insulating varnish layer, wherein at least one at least electrically conductive conductor track is printed on at least some areas between the primer layer and the varnish layer is proposed. In order to increase the reproducibility of the coil coating method, it is proposed that the conductor track be printed on some areas of the pre-cured primer layer and that the conductor track and varnish be applied using a wet-on-wet process.

    Abstract: A coating method of reflective film is first to prepare a glass beads film and then select a color to be coated. The color is composed of plural primary colors in fixed ratio, making the color have a standard ratio, which is obtainable from an original database. Next, ratios of the primary colors are respectively adjusted to form a printing ratio according to color fastness, permeability and light barrier property of each primary color attached to the glass beads and then, each primary color is orderly spray coated on the glass beads film to form a coating layer with micro-printing technique in accordance with the printing ratio, thus completing manufacturing of a reflective film with high transmittance and high wide angle.

    Abstract: An applicator assembly for treating a surface includes a material applicator configured to dispense a treatment material on a surface and an applicator clamp configured to support and position a dispensing end of the material applicator. An applicator tip is inserted into a dispensing aperture formed in the applicator clamp, and the applicator tip is configured to receive the treatment material from the dispensing end of the material applicator. The applicator assembly further includes an applicator bracket configured to slidably attach the material applicator and applicator clamp to an assembly support frame. Additionally, an automated applicator actuator operatively attached to the assembly support frame and applicator bracket manipulates the applicator bracket between a first position and a second position.

    Abstract: An apparatus (100) for dispensing a brushable substance (102) comprises a bracket (104) and a sleeve (110), comprising an inner tubular sleeve wall (114) and an outer tubular sleeve wall (112). The sleeve (110) is coupled to the bracket (104) and is rotatable relative to the bracket (104). The apparatus (100) also comprises a cartridge (124), comprising an inner tubular cartridge wall (126) and an outer tubular cartridge wall (128). The apparatus (100) additionally comprises a valve (140), configured to be communicatively coupled with the cartridge (124), a brush-arm assembly (152), coupled to the sleeve (110), a linear actuator (138) to control flow of the brushable substance (102) from the valve (140), an annular plunger (148), positioned between the inner tubular cartridge wall (126) and the outer tubular cartridge wall (128), and a twist-lock pressure cap (150), configured to be hermetically coupled with the cartridge (124). The cartridge (124) is configured to be positioned between the inner tubular sleeve wall (114) and the outer tubular sleeve wall (112) and between the twist-lock pressure cap (150) and the valve (140).
