  • Patent number: 10196305
    Abstract: A vacuum repairing tool for a crack/seam on surface of an object includes an injector for extracting air and injecting glue, and a sticky pad for fixing on an object surface. A perfusion repairing area corresponding to the crack/seam and glue applying areas for applying glue are arranged on the bottom surface of the sticky pad, and the glue applying areas are on the outer sides of the perfusion repairing area. The injector is provided with a needle. The invention can forcibly perfuse the repairing liquid into the crack/seam by external force in the vacuum state, so as to ensure the sufficient and uniform perfusion of repairing liquid without blind space, it even isolates the contact of the glued space with the outside to realize the genuine dust-free operation, thus it solves the long-existing universal difficulty that the crack/seam on surface of object can't be fully and seamlessly repaired.

  • Patent number: 9211677
    Abstract: An inkjet printing method for forming a continuous three-dimensional structure is disclosed. A pre-patterned temporary structure is formed on a substrate for defining a filling groove on the substrate. An inkjet printing process is performed for filling the ink droplets into the filling groove. The ink droplets cover the filling groove and contact the surface of the temporary structure and the substrate at the same time. A self-aligned effect is formed by a composition of the gravity of the ink droplets, a surface tension between the ink droplets and the temporary structure, and a surface tension between the ink droplets and the substrate. When the ink droplets are solidified, a standalone continuous three-dimensional structure is formed by removing the temporary structure. The geometry of the continuous three-dimensional structure can be defined by the temporary structure; therefore a small track width of the solidified ink droplets can be obtained.

    Abstract: A method for producing molded products using coffee grounds in which coffee grounds are collected from coffee shop and then dried, fractioned, and ground, after which the thus-processed coffee grounds are mixed with purified water and binding agent, and the resultant mixture is poured into a mold to be compression molded into various shapes, e.g. cubes. The thus-molded articles may replace existing soaps used for practicing carving so as to prevent wasted resources and environmental contamination. The method for producing molded products using coffee grounds according to the present invention enables a minimal addition of chemicals during molding so as to provide practice materials which are harmless to the human body.

  • Patent number: 8765039
    Abstract: Bio-implantable textured tubular and sheet structures of un-sintered ePTFE are described. Such micro-textured structures stimulate robust development of beneficial bio-integrative scar attachment to adnexal soft tissues. Methods for texturing one side of an un-sintered extruded ePTFE tube or sheet are also described. A select length of tubing of any thickness or diameter is applied over a matching mandrel and adhesively stabilized thereon by applying intense suction. The texture is made by “RIGDA tooling” into the wall thickness of the material and by removing undesired material by distraction and avulsion tooling and methods assisted by vibration, leaving intact the finished product. Disclosed is an implantable, non-attached, enveloping, conforming and supportive drainage cover for breast and other soft implants.

  • Patent number: 8739409
    Abstract: The invention relates to a method for manufacturing products by applying material at least partially in layers to form a structure, in particular by selective laser melting (SLM), said method comprising the steps of: (a) providing a base plate, (b) applying a layer of a curable material, (c) selectively curing predetermined zones of the applied layer on the basis of geometrical data of the product, (d) repeating steps (b) and (c) until the geometry of a first partial volume of the product has been created in the form of a cured material and (e) removing the uncured material. According to the invention, a reference mark is provided, the unit formed by the base plate and the first volume zones is clamped into a specific position by means of the reference mark and the respective second partial volume of the respective product is cut from the base plate, preferably by machining, in particular CNC milling.

  • Patent number: 8691136
    Abstract: A device is formed by the process into a bone screw or fastener, wherein the head has a degree of polymer alignment and strength, and wherein the shank has a higher degree of polymer alignment and strength. In practice of the present invention, the polymer slug is pressed into the die cavity by the actuation of ram press, causing the slug to conform to the die cavity. Through this process, the polymer molecular orientation is aligned to different degrees, in different zones of the device.
