  • Patent number: 9833788
    Abstract: The invention describes powders for use in the production of spatial structures, i.e. molded bodies, using layer build-up methods, as well as methods for their efficient production. The powders have the special feature that they have good flow behavior, for one thing, and at the same time, have such a composition that the molded body that can be produced with the powder, using rapid prototyping, has significantly improved mechanical and/or thermal properties. According to a particularly advantageous embodiment, the powder has a first component that is present in the form of essentially spherical powder particles, which is formed by a matrix material, and at least one further component in the form of stiffening and/or reinforcing fibers, which are preferably embedded in the matrix material.

  • Patent number: 9770134
    Abstract: The present application relates to an apparatus for processing a food stuff. The apparatus has a housing (2), and a cutting tool (5) rotatably mounted in the housing (2) having a cutting edge (35) and a trailing edge (31). The cutting tool (5) is arranged to pass once per revolution through a processing region (43) in the housing in which a food stuff is receivable, and to pass through a recovery region (45). The recovery region is defined in the housing between the trailing edge passing from the processing region and the cutting edge passing into the processing region as the cutting tool rotates, and the cutting tool is free to rotate in the processing region without contacting the food stuff. Therefore, the cutting tool (5) acts on a food stuff as the cutting tool rotates through the processing region, and recovers the rotational speed lost due to acting on a food stuff in the processing region as the cutting tool (5) rotates through the recovery region.
