Abstract: A solvent blend for breaking down and reducing the viscosity of petroleum substance consists essentially of one or more methyl esters of C14-C18 fatty acids, one or more C9-C20 low aromatic hydrocarbon solvents, and one or more C4-C8 high aromatic hydrocarbon solvents, with the high aromatic solvent fraction being dispersed within the solvent blend in droplet form. The solvent blend may be produced by mixing the high aromatic solvent fraction into an intermediate or base blend consisting essentially of the methyl ester fraction and the low aromatic solvent fraction, with the base blend being produced by mixing the lower aromatic solvent fraction into the methyl ester fraction such that the lower aromatic solvent fraction is dispersed within the methyl ester fraction in droplet form.

Abstract: An optical mouse light emitter has a transparent body, a divergent light-emitting component and a disc reflective structure. The transparent body has a front end surface and a lateral circular surface. The light-emitting component is built in the transparent body. The disc reflective structure is built on the lateral circular surface. The disc reflective structure has an internal surface. The light emitted from the light-emitting component through the front end surface of the transparent body forms a light collection area. The light emitted from the light-emitting component to the internal surface of the disc reflective structure is reflected by the internal surface to form an axial parallel light and focused at the light collection area for reducing the light interference and enhancing the illumination so as to improve the light sensing effect of the optical mouse, lower its cost and reduce its electric power consumption.

Abstract: A light apparatus of an optical mouse with an aperture stop and the light projection method thereof are described. The light apparatus has at least one image-forming lens and an aperture stop. The image-forming lens defines an interior area and an external area. The aperture stop has a pupil. The aperture stop shelters the external area of the image-forming lens. The pupil of the aperture stop corresponds to the interior area. The present light apparatus will not produce a light halo on the image detection unit of the optical mouse when the light source of the optical mouse projects a light that passes through the image-forming lens of the light apparatus. Therefore, the image detection unit clearly detects the image of the image detection surface.

Abstract: A light projection method and apparatus for an optical mouse is provided. The light projection method and apparatus for an optical mouse comprises: provides a light projection apparatus and projects a light into the light projection apparatus to form a first light beam and a second light beam. The first light beam is vertically projected to a detection area of an image detection surface and the second light beam is slantwise projected to the detection area of the image detection surface. The first light beam allows the image detection unit of the optical mouse to exactly detect the image on the detection area. The second light beam makes the contrast between the concave and the convex of the detection area become more obvious and the ability of the image detection unit of the optical mouse to detect and identify the on the detection surface is effectively enhanced.

Abstract: An optical image retrieval method, which makes optical input devices work on transparent media, which method generates a light and projects it in a vertical direction. The light is directed to a light-splitter and transmitted to an image contacting surface under a transparent medium. Optical image signals retrieved on the image contacting surface are reflected to the light-splitter, and then an optical axis of the image signals is reflected to a lens by the light-splitter once or more. Finally, the lens will focus the image signals onto an image detecting element.

Abstract: A nail tip adhesive is made by the process of mixing cyanoacrylate and a vitamin fortifier in a proportion by weight in the range of 0.0001% to 0.1% vitamin-to-cyanoacrylate, wherein the shelf life of the cyanoacrylate is at least not substantially shortened by adding such vitamin. Such vitamin fortifier comprises at least one of vitamin A, vitamin D-3, vitamin E, vitamin K, vitamin B-1, vitamin B-2, vitamin B-6, vitamin B-12, vitamin C, niacinamide, folic acid, panthothenic acid, and biotin.

Abstract: An adhesive patch includes an applique of material with one side covered in cryanoacrylic ester tissue glue with dimensions sufficiently large to cover the natural pelvic vents of beef and pork carcasses. The material appliques are dispensed with glue applied at the moment of use on an animal slaughter processing line.

Abstract: A dropper, press fitted into the neck of a cyanoacrylate adhesive dispensing container, includes an elongated nozzle having a constant diameter passageway. The inlet to the nozzle is defined by a downwardly depending hollow boss having a sharp edged perimeter and sharp edged orifice. The sharp edged orifice and sharp edged perimeter tend to discourage retention of any droplets of cyanoacrylate adhesive to maintain the inlet free of residual cyanoacrylate adhesive and free of the crusting and clogging of the inlet which might otherwise occur.

Abstract: A constant diameter or segmented constant diameter passageway within a dispensing tip channels and dispenses a cyanoacrylate adhesive from a container through a discharge outlet at the extremity of the tip. A stopper for the tip includes a plunger for matingly and penetrably engaging the passageway to force reverse flow of the cyanoacrylate adhesive back into the container. The forced flow, due to the viscosity and surface tension characteristics of the cyanoacrylate adhesive, initiates complete drainage of the passageway and prevents any crusting and clogging of the cyanoacrylate within the passageway. The stopper is manufactured attached to the end of the tip at a weakened junction for breakaway separation by the ultimate user, which junction insures the establishment of a sharp edged discharge orifice at the tip to promote accurate dispensation of cyanoacrylate adhesive and to prevent clogging of the orifice.

Abstract: A constant diameter passageway within a dispensing tip channels and dispenses a cyanoacrylate adhesive from a container through a discharge outlet at the extremity of the tip. A cap for the tip includes a plunger for matingly and penetrably engaging the passageway to force reverse flow of the cyanoacrylate adhesive back into the container. The forced flow, due to the viscosity and surface tension characteristics of the cyanoacrylate adhesive, initiates complete drainage of the passageway and prevents any crusting of the cyanoacrylate within the passageway and clogging of the passageway.

Abstract: A two phase interlock secures a cap to a container of a fluid. The interlock includes flanges extending from the cap for engaging lugs located about the mouth of the container which flanges are disengageably engagable with the lugs by rotating the cap relative to the container and a key extends from the cap into a key way in the container to prevent rotation of the cap relative to the container without withdrawal of the key from the keyway by deliberate precise flexing of the cap.
