Title: Fluid circulation control for central heating system - uses transverse couplings between parallel circulation tubes to form selectively opened circuits
IPC: F24D19/10
Filed: 1980-12-31
Abstract: The central heating system has a central boiler, solar heating panels etc. radiators for space heating, heat storage devices and heat exchangers. The different elements of the heating system are interconnected via a fluid circulation control for optimum operation of the system. The circulation control has pairs of parallel tubes each connected across the input and output of one of the elements and allowing the distribution pumps and the control valves to be installed as required in each of these tubes. Transverse tubes can be connected between the two tubes of each pair, or between the tubes of different pairs to provide an arbitrary number of circulation circuits. The latter circuits are opened and closed either manually or automatically via a microprocessor control so that the heat distribution is of variable capacity.

Title: Production of calcium-sulfate hemihydrate using waste heat, diluted sulfuric acid and sulfuric salts.
IPC: C04B11/02
Filed: 1981-07-14
Abstract: Alpha gypsum hemihydrate is obtained by calcining calcium sulfate dihydrate, generated with flue-gas desulfurization of power plants or by chemical process, e.g. in the production of phosphoric acid. The calcining process comprises producing initially a dispersion from calcium sulfate dihydrate and diluted, sulfuric acid solution and heating same at a predetermined rate to about 373 K with industrial, dust-free waste heat, whereupon the solid components are separated from the aqueous sulfuric acid and are dried. An alpha gypsum hemihydrate practically free from anhydrite II is obtained from a solution of sulfuric salts in the diluted sulfuric acid. An addition of magnesium oxide yields a hemihydrate with a high degree of fineness and avoids blooming effects.

Title: Method of and device for making a package.
IPC: B65B61/12
Filed: 1982-04-15
Abstract: In the manufacture of multiple packagings, it is advantageous to produce a uniform pack size in order to be able to work efficiently. However, this does not usually meet the wishes of the manufacturers and the consumers. A method is therefore proposed by means of which relatively large packagings are manufactured to be divided up into the particular desired size at the end of the production process. This is done by equipping the packaging sleeve with a perforated line along which the packaging can be separated. The packaging sleeve has a cover side with which it bears on the packaged articles, and two side walls. The apparatus has two rotatably mounted levers in a first station which permit the perforated lines in the two side walls to be broken open, and, in a second station, has two abutments as well as a pressure-transmitting element, which together permit the cover side of the jacket to be broken open along the perforated line there.

Filed: 1983-07-27
Abstract: A process for the recovery of zinc from zinc-containing sulphidic material which also contains iron and from zinc oxide containing material, at least one of the materials containing lead and/or silver values. The process includes leaching zinc-containing sulphidic material and zinc oxide containing material under pressurized oxidizing conditions at a temperature in the range of from about 130 DEG to about 170 DEG C. in aqueous sulphuric acid solution with a stoichiometric excess of sulphuric acid relative to the zinc content of the materials of from about 40 to about 100% to produce a residue containing a major proportion of lead and/or silver values and a leach solution containing a major proportion of the zinc and iron. The residue is separated from the leach solution and treated to recover lead and/or silver values.
