The present invention has multiple aspects. In its simplest aspect, the present invention is directed to an intermediate bone block comprising a machined segment of cortical bone, cancellous bone or both, the intermediate having a face comprising one to ten compression surfaces and one to ten cavities, the compression surfaces suitable for compressing soft tissue, the cavities for receiving and holding overflow soft tissue. The cavities are preferably channels, and more preferably channels having an omega cross-sectional profile. Surprisingly, the cavities and channels, which reduced the compressed surface area between the intermediate bone block and the tendon, significantly improved tendon load at failure. In standardized tests, an intermediate bone block of this invention, when combined with high surface area bone blocks of the prior art bone blocks, unexpectedly increased their load at failure. The invention is also directed to bone block assemblies suitable for binding to a soft tissue to form an implantable graft, and to such implantable grafts. A particularly preferred graft is a bone-tendon-bone graft.

A polishing disc for a tool for the fine machining of optically active surfaces, particularly on spectacle lenses as workpieces, comprises a main body which has a center axis and on which there is fixed an intermediate layer which is softer than the main body and on which a polishing agent carrier rests. The intermediate layer has, with respect to the center axis, a radial inner region of substantially constant axial thickness and an adjoining radial outer region. The latter is formed or is fixed to the main body in a particular way so as to prevent the edge of the polishing disc from being imprinted on the machined surface of the workpiece in the form of very fine, scratch-like microstructures. Also proposed is a simple method which can be used to produce such a polishing disc.

The invention belongs to the technical field of preparation of a film material, and discloses a solution film formation method and device of an organic material. The method comprises the following stages of dissolving the organic material in a mixed solvent containing a high-boiling point solvent and a low-boiling point solvent, and depositing the organic material on a substrate by a film formation technology to obtain a liquid film; and carrying out normal-pressure evaporation on the substrate containing the liquid film under conditions of rotation, variable frequency vibration and programmable temperature rise to remove the low-boiling point solvent, stopping rotating and vibrating, evaporating the high-boiling solvent under conditions of vacuum and programmable temperature rise to obtain an organic material film. The substrate is shaken in a reciprocating way through rotation and variable frequency vibration, so that the solution keeps flowing, the difference between the edge and the middle of the solution is reduced, and the difference of the surface and the interior of the solution is reduced; and meanwhile, the thermal motion of solvent molecules is accelerated by programmable temperature rise, and the film formation quality of the solvent during the drying process is improved.

The present invention relates to metal decorations for displaying a logo or a trademark of goods or a company in the form of characters or figures on the surface of various products. More particularly, in order to have securing legs and connecting rods with a thinner thickness than the thickness of the metal decorations, the metal decorations and the securing legs are formed by corrosion; a product and a rear plate are each punched at positions corresponding to the securing legs; and after severing the connecting rods of the securing legs, each of the metal decorations is secured to the product and rear plate. Accordingly, even if the securing legs are bent, due to the securing legs being formed with a different thickness from the metal decorations, the borders of the metal decorations are unaffected, thus, it is possible to manufacture the metal decorations with distinct borders, and it is possible to improve workability as well as reducing damage to the product by reducing the thickness of the securing legs. In addition, the metal decorations or the securing legs are prevented from protruding from the surface of the product or the rear plate, due to grooves being formed, in the rear plate for securing the metal decorations, with a depth corresponding to the thickness of the metal decorations or the thickness of the securing legs, thereby achieving effects of producing a more luxurious product and providing an elegant exterior.
