Abstract: The object of the invention is to simplify the production of woven, endless tire reinforcing belts by enabling rapid, economical changes in belt size and simplified removal of the belts from the weaving apparatus. The invention provides a method and apparatus for forming reinforcing belts which meet this objective by employing an endless weaving surface comprised of a flexible belt supported by means rotatable about spaced, parallel axes. By moving the supports apart, the weaving surface is tensioned for the weaving operation; and, by moving the supports toward one another, the weaving surface is relaxed to permit removal of the woven reinforcing belt. The circumference of successive reinforcing belts can easily be changed by changing the flexible belt comprising the weaving surface.

Abstract: A free-flowing granulate of a powder-form or fine-grained component and a liquid component; the granulate containing at least 20% by weight of the liquid component, is prepared by moving the powder-form or fine-grained component in a mixer-granulator, adding the liquid component while mixing until a moist granulate having a particle size of at most 1.5 mm is obtained, subsequently coarsening the granulate thus obtained with an increase in temperature to a particle size of from 0.4 to 4 mm and optionally coating this coarse granulate with another powder-form and/or fine-grained component at 60 DEG  to 90 DEG  C. The optionally coated granulate is converted by lowering the treatment temperature into a dry-looking, free-flowing, coarse-grained product, which if desired, may be coated with another powder-form and/or fine-grained material. Despite the high percentage of a liquid component, the granulate thus obtained appears as a dry granulate and is free-flowing.

Abstract: An apparatus for gasifying solid carbonaceous material in a circulating fluidized bed reactor (1). Particles are separated from the product gas at least in two stages so that in the first stage (2), mainly coarser, so-called circulating particles are separated and returned to the reactor. In the second stage (5), fine carbonaceous and ash-containing particulates are separated from the gas and are made to agglomerate at a raised temperature. Coarser particles thus received are returned to the reactor through a return duct (3, 33) together with circulating particles. Agglomeration is effected in a chamber (30), where a fluidized bed (31) composed of coarse particles is maintained. Fine particulate material (38) and oxygen containing gas (39) are introduced into the free upper part of the chamber so as to form a flame (40). The point of the flame penetrates into the fluidized bed. The ash material contained in the fins particulate material melts, and is conducted to the bubbling fluidized bed (31).
