Abstract: A compression molding apparatus for particulate matter comprising a magnetostrictive actuator functioning as an impact force applying means arranged at least between an upper ram or a lower ram and an upper punch or a lower punch. Particulate matter is compressed by a static pressure, and then an impact force is applied to the particulate matter to reduce internal stress. After compressing the particulate matter by the static pressure, the upper ram is allowed to fall gravitationally to shorten a molding time.

Abstract: Disclosed are aerosol-mediated methods for synthesizing particles for biomedical and drug delivery applications. The method is based on the production of particles from sprayed polymeric micro or nano-droplets obtained by, for example, an air-jet nebulization process that is followed by gelation and/or hardening in a crosslinking fluid, non-solvent, precipitating solvent, or supercritical fluid.

Abstract: Coal compacts which are suitable for coking in coke oven chambers are prepared by pressing and compacting coal in a pressing device having a design which shapes the surface of the coal compacts to provide higher surface area. Already compacted coal blocks can be pressed to generate the surface shape. The resulting coal compacts exhibit significantly improved properties during the coking process, resulting in improved gas and heat exchange. A device for compacting coal preferably contains a plate provided with shaping elements on the pressing surface.

Abstract: The present invention relates to a process for the wet production of granules from powdered materials, in particular raw materials for the production of glass. The process of the invention comprises the following successive steps: (i) the powdered materials to be granulated are divided into at least two portions: a first portion and a second portion; (ii) a binder liquid is added to the first portion of powdered materials; (iii) the first mixture thus obtained is agglomerated in the granulator in order to obtain granules (a); (iv) the second portion of powdered materials is added to the granulator; and (v) the new mixture obtained is agglomerated in the granulator in order to obtain granules (b). This sequenced granulation process allows granules to be obtained that have a degree of moisture that assures their stability and their ease of handling eliminating the drying step.

Abstract: A method and apparatus is provided for preventing a composite material used in forming slabs for residential and commercial construction from entering a predefined space that is maintained open for pipes, plumbing fixtures and other conduits. The preform apparatus comprises a body, apron and cover. The apparatus is assembled by placing the preform body in position to occupy a predefined space, press fitting the apron down over and around the body and the cover on top of the body. Thereafter, the composite material is poured around the preform and allowed to cure. After curing, the preform body and the cover are removed, leaving a material free void within and below the predefined space that the preform had occupied. The preform is straightforward, inexpensive to produce, easy to use and is assembled without fasteners and without disturbing the soil below the slab or the moisture/vapor barrier.
Abstract: The invention relates to a method for producing a sheet from renewable raw materials. In the method, after mixing a composition to produce a sheet from renewable raw materials, this composition is applied to a conveyor belt. Protruding materials or unevennesses are eliminated with the aid of a device, preferably a simple doctor blade. Without supplying heat, the composition is then subjected to a first drying process on the conveyor belt, before the endless sheet created in this way is cut into sections. The sections are then passed on to final drying in a storage device. After complete drying, regions at the extremities of the sections that have been adversely affected by cutting up the endless sheet are removed from these sections and chopped up into chips. These chips are returned to the further production process in a final method step by feeding them into the composition for producing a sheet from renewable raw materials.
Abstract: A method for producing leather pellets, and a method for producing compound granules from leather pellets and a polymer material, for use in molded parts or films. The leather pellets are produced through the following steps: Shavings, crust leather remnants and finished leather waste are obtained as waste products in leather production and finished leather processing; the shavings, crust leather remnants and finished leather waste are milled into ground leather stock comprising leather fibers; the ground stock is pressed into leather pellets; and the leather pellets are dried to a residual moisture content of no more than 30% by weight. The leather pellets can be mixed with a polymer material at a ratio of 10-95% by weight and bonded to one another and shaped forming compound granules. The compound granules can be used to produce molded parts by injection molding or films by calendering.
