Patent IE-791870-L (IE)
Title: Edible coating
IPC: A61K47/32
Filed: 1979-10-02
Abstract: Pharmaceutical coatings in the form of aqueous dispersion of a water insoluble polymer prepared by dissolving the polymer in a water immiscible organic solvent, emulsifying the organic solution in water, optionally with the aid of additives, and stripping the organic solvent from the system to provide a colloidal, or near colloidal, aqueous dispersion or latex of small, even sized polymeric particules which are applied to pharmaceutical dosages from highly loaded latices. The latexes, which display resistance to bacterial and mold growth and, when combined with selected additives, provides convenient, attractive coating compositions which afford excellent protection and varied release properties to pharmaceutical dosages.

Patent NO-811613-L (NO)
Inventor: HILL RICHARD C
IPC: F24H1/22
Filed: 1981-05-12
Abstract: A stove or furnace for efficient combustion of wood fuel includes a vertical feed combustion chamber (15) for receiving and supporting wood fuel in a vertical attitude or stack. A major upper portion of the combustion chamber column comprises a water jacket (14) for coupling to a source of water or heat transfer fluid for convection circulation of the fluid. The locus (31) of wood fuel combustion is thereby confined to the refractory base of the combustion chamber. A flue gas propagation delay channel (34) extending laterally from the base of the chamber affords delayed travel time in a high temperature refractory environment sufficient to assure substantially complete combustion of the gaseous products of wood burning with forced air prior to extraction of heat in heat exchanger (16). Induced draft draws the fuel gas and air mixture laterally through the combustion chamber and refractory high temperature zone to the heat exchanger and flue. Also included are active sources of forced air and induced draft, multiple circuit couplings for the recovered heat, and construction features in the refractory material substructure and metal component superstructure.

Abstract: A metal frame arrangement (20, 21), for use as or in door frames, window frames (22), window casements (23) or the like, comprises a frame made of concave metal profile. The frame (20, 21) comprises two pairs of mutually opposite frame portions which are angled at right angles relative to the adjacent neighbouring frame portion. The frame (20, 21) is made into a coherent piece in a longitudinal continuous and sectionally angled contour, by means of local cavities (31, 35) in the metal profile and longitudinal deformation of locally uncovered portions (32, 36, 37) of the metal profile, the deformation by means of the material of the metal profile forming angle reinforcing and angle bracing means (32', 38) just by the apex of the angle between two neighbouring frame portions. A process for the production of the metal frame (20, 21) comprises that cavities (31, 35) in a side portion or side portions of the profile are removed, after which a section of web portion (20c) or one web portion (21f) of the profile uncovered by the cavity (31, 35) is finished to form an angle bracing and angle reinforcing means (32', 38) for establishing frame portions angled at right angles relative to each other. The angle bracing is effected simultaneously with the undertaking of the angle bending of the frame plate.
