Abstract: An improved wet granulation process for preparing compressed tablets, particularly those containing a poorly compressible medicament, e.g., paracetamol and derivatives thereof, the improvement which comprises homogenizing part only of particulate solid material including active matter and tabletting aids with at least 90% by weight of a predetermined quantity of granulating fluid, so as to form a substantially homogenous slurry wherein the percentage of weight of solids, both dissolved and undissolved, in the slurry is at least about 25% w/w; and then moistening the remaining part of the particulate solid material in the manner of wet granulation but with the slurry resultant from above (and thereafter with the balance of the granulating fluid, if any) so as thus to form a desired substantially uniform, moist, coherent, non-pasty mass ready for granulation. Said mass is then granulated and dried, and the dried granules compressed and compacted into tablets.

Abstract: The present invention relates to a method for producing lightweight granules of sodium tripolyphosphate from a powderous sodium-phosphate mixture. The material is first processed in the schugi-mixer, while adding a given quantity of water thereto, whereafter the moist mixture is fed to a rotating calcining furnace, to which the given, remaining quantity of water is supplied to the material prior to calcination.

Abstract: Apparatus is provided for the production of atomized metal comprising a containment vessel having a sidewall terminating in a bottom plate through which atomizing gas and molten metal from a molten metal source external to said vessel enter said vessel through nozzle means sealed thereto. An air ingress port is provided in the vessel spaced from said bottom plate; the sidewall and bottom plate cooperating with said nozzle means to seal off the interior of the vessel and the metal particles therein from the area adjacent the source of molten metal; thereby providing an essentially closed vessel, particularly with respect to the area in which the nozzle means are mounted.

Abstract: An elastomeric spring is formed by extruding a rubbery material into a reinforcing sleeve in a mold during relative motion between the mold and nozzle, and thereafter vulcanizing.

Abstract: The invention relates to a process comprising the cooling and comminuting of molten calcium carbide, wherein a molten stream of calcium carbide is tapped off from a furnace at 1900.degree. to 2100.degree. C., cooled and comminuted. More particularly, the molten calcium carbide is initially comminuted into droplets and the droplets are cooled to less than 200.degree. C. The process can be carried out with the aid of an apparatus comprised of a heatable or coolable feed duct, a nozzle for comminuting the molten stream, and a series of fluidized bed cooling zones.

Abstract: An apparatus and method for producing fiber reinforced plastic composite articles which have a length and where the shape of and volume of material in the composite across its length is not necessarily uniform. The apparatus receives filament containing reinforcing material, as for example, strands of filament reinforcing material impregnated with a hardenable binder such as a curable resin. The apparatus also includes a device for forming cores or plugs from a bulk-molding compound, roughly in the form of the desired shape of a portion of the article to be produced. Thereafter, the resin impregnated fiber containing reinforcing strands are disposed about each of the plugs which are draped over a continuous string to from a chain of the plugs on the string. The impregnated strands preferably enclose the plugs to form a composite therewith.
