Abstract: The present invention provides for a method of creating a lustrous surface in opaque materials using ridge angles, and valleys of varying depths cut, imprinted or pressed into the opaque material. The combination of the light reflecting ridges, angles to reflect more or less light, and a shadow effect arising from a combination of the valley depths and the angle of the ridges allows one to use light and shadow to create a pattern or series of patterns in the opaque materials. These patterns are created using a process whereby a design is first created, then cut into a master blank using some type of manual or computer-aided method. Next, this pattern is inlaid, pressed, or imprinted into a blank panel composed of the opaque material. In some embodiments, this opaque material is allowed to set, thus creating a finished article of manufacture in the form of a panel.

Abstract: A precursor yarn or thread is made by passing a central element, e.g., a filament, a tow, or a flat member, through a bath of a binder, such as a low-temperature hot-melt adhesive, and aqueous urethane, or an acrylic material, with which is mixed a quantity of hard-shelled microspheres which expand when heated to a higher temperature. This is then covered by a sheath, e.g, of PVC, polyurethane, polyester, acrylic resin, polycarbonate, polypropylene, or polyethylene in a second bath. When this product is heated to a transition temperature which is characteristic of the microspheres chosen, the microspheres expand, swelling the sheath. Such a precursor could be woven into a fabric and then heated, so that as the yarn expands the fabric mesh becomes tighter, reducing its porosity. This would be useful as a yarn in making papermaker's felts.

Abstract: A method for forming an acetabular shell includes providing a working surface such as a mandrel, and spraying the working surface with a first layer of material having a first composition such as aluminum oxide. After a suitable thickness is generated, the spray composition is gradually changed to other compositions having desired particle sizes and distribution. In one example, the composition is changed to a mixture of aluminum oxide and titanium oxide and/or titanium. As thickness builds up, the relative amount of aluminum oxide is decreased such that the composition is all titanium and titanium oxide. After a desired thickness is generated, the acetabular shell is extracted off the mandrel.

Abstract: An apparatus for the artificial ageing of blocks, in particular concrete blocks, clinker bricks and natural stone blocks, has a base on which the blocks can be placed in such a way that their surfaces to be treated and the adjoining edges are exposed. Essentially freely movable striking bodies are used for treating the surfaces and the adjoining edges of the blocks. A vibrating device sets the blocks and the striking bodies in motion relative to one another in such a way that the striking bodies act on the surfaces and the exposed edges of the blocks. In this case, the striking bodies are movably fastened to a retaining device in such a way that the striking bodies are freely movable within a defined region of the surface of the blocks.
