Abstract: A method for spreading a conformable material between a substrate and a template having a mold. The method comprises positioning the mold to be in superimposition with the substrate defining a volume therebetween. A first sub-portion of the volume is charged with the conformable material through capillary action between the conformable material and one of the mold and the substrate. A second sub-portion of the volume is filled with the conformable material by creating a deformation in the mold.

Abstract: A bladder is made to be expandable and contractible at a vulcanization position within a lower mold assembly and to be expandable and contractible also at a tire delivery position which is spaced a predetermined distance from the vulcanization position along a center axis of the lower mold assembly. With a centering shaft passing through an upper mold, the bladder and the lower mold assembly, a green tire loaded into the tire delivery position is held by the bladder by expanding the bladder and is loaded by the bladder into the lower mold assembly. After a vulcanization processing, the bladder removes the vulcanized tire from the vulcanization position to the delivery position, and after the centering shaft is drawn out from the lower mold assembly and the bladder, the bladder is contracted at the delivery position to make it possible to release the vulcanized tire from the bladder.

Abstract: The present invention provides a method of producing porous structures, particles or matrixes, which may be comprised of one or a plurality of components, an apparatus for carrying out the method and particles formed in accordance with the method. The method is particularly suitable for producing porous composite or pure particles for pharmaceutical applications. In accordance with the method, a composite comprising a material such as a pharmaceutical, a biodegradable polymers and/or a biological agent is formed. The composite must further comprise a material that is soluble in supercritical fluid. Extraction of the supercritical fluid soluble material produces porous structures, which may be in the form of particles or matrixes.

Abstract: Displacers are used in production of concrete surfaces. The displacers are embodied, for example, as plastic balls or plastic shells and are locked in lattices that are open on one side, preferably downwardly. The modules can then be pressed into a first or second concrete layer that can already contain a first reinforcement mesh. The thus produced semi-finished product can then be covered with a concrete mass during the subsequent finishing process.

Abstract: In the sector relating to the technology of compaction by means of vacuum vibro-compression for manufacturing slabs or blocks, the organic binder resin consists of an aqueous dispersion of acrylic prepolymer in water and a filler part consists of a hydraulic binder in an amount sufficient to fix wholly or partly the water present in the initial mix; after the vibro-compression step the rough-formed article is subjected to a hardening and curing step in conditions such as to prevent the evaporation of the mix water and subsequently to a heating step so as to obtain crosslinking of the acrylic polymer. If the acrylic binder alone is used, an article with a high degree of porosity is obtained.

Abstract: The invention relates to an adjustment method, especially for the adjustment of optical or fiber optical components, whereby a partial region of an actuator is locally heated in such a defined manner that compressive stresses are created therein as a result of the restricted thermal expansion of said heated partial region, caused by at least one other partial region of the actuator. If the yielding point ? of the material of the partial region is exceeded, said compressive stresses lead to the plastic compression of the heated partial region. Furthermore, said heated partial region is contracted during cooling and leads to a defined modification of the geometry of the actuator following the cooling process. Tensile stresses are created as a result of a restriction of said contraction by means of at least one other partial region in the previously heated partial region, and compressive stresses are frozen in the at least one other region.

Abstract: A resin infusion system uses a housing that has an upper flexible diaphragm and a lower flexible diaphragm such that the two diaphragms form a cavity. A fiber reinforcement mat is positioned within the cavity. A mold is positioned below the lower diaphragm. A flow plate has a series of V-shaped grooves and is positioned either underneath the lower diaphragm or overtop the upper diaphragm so that the grooves press into the respective diaphragm. A vacuum is created within the housing causing resin to be drawn into the cavity with the resin interacting with the grooves increasing the turbulence of the resin flow. Once the reinforcement mat is properly wetted, the mold is pressed into the lower diaphragm.

A core is positioned on the first band and the second band is positioned on the first band. Rim well rings are positioned from outside on the second band, to abut the sides of the second band. A spreader ring is inserted between the rings to join the material near the upper rim flanks and the rim flanges.
