Title: Refractory Lining Means for Metal Melting Furnaces
IPC: F27D1/00
Filed: 1979-10-09
Abstract: A refractory lining mass which has a long service life in view of its resistance to metallurgical erosion contains, in addition to the usual granular base material (e.g. quartzite, mullite), at least one deoxidizing agent for the oxide(s) of the metal (e.g. iron- carbon alloy) to be melted in the furnace. The agent is present in any amount of 0.1 to 5% by weight of the mass and preferably has a maximum grain size equal to that of the granular base material.

Patent ES-8106404-A1 (ES)
Title: Process and arrangement for examining a body by means of penetrating rays.
IPC: A61B6/03
Filed: 1980-09-25
Abstract: Devices that measure the electron density in a body by means of radiation scattered from a narrow pencil beam of penetrating radiation directed through the body, produce defective images on reconstruction of the density distribution because of multiple scattering of radiation. This can of course be reduced by scattered ray diaphragms, but cannot be eliminated entirely. The invention therefore provides a means for detecting the size of the multiple scattered radiation component be measurement. For this purpose, the detector array which measures radiation including the single scattered radiation, is screened, at least osscasionally, from the single scattered radiation and the detected intensity values measured by the detector elements when so screened, are used to correct the values generated by measuring the detected radiation including the single scattered radiation.

Title: Process for the manufacture of potassium nitrate
IPC: C01D9/04
Filed: 1981-04-20
Abstract: The present invention relates to a process for the manufacture of potassium nitrate from potassium chloride and nitric acid. According to the invention, potassium chloride and nitric acid are reacted in an aqueous medium at a temperature in the range of between -25 DEG C. to +10 DEG C. From the brine solution obtained after the separation of the resulting potassium nitrate, nitric acid is extracted by an organic solvent solution containing at least one compound selected from the group consisting of ketones having five to ten carbon atoms, straight or cyclic polyethers having molecular weight in the range of 100 to 1000, polyalkylene glycols slightly miscible in water and having molecular weight in the range of 1000 to 3000, and organic esters of phosphoric acid, phosphonic acid and phosphinic acid, or mixtures thereof, in an organic diluent which does not substantially extract hydrochloric acid. The remaining aqueous solution consists of a substantially nitrate-free brine containing hydrochloric acid. The NO3--loaded solvent is washed, the nitric acid as well as the organic solvent being respectively recycled in the process. The process saves appreciable amounts of nitric acid. Optionally, pure hydrochloric acid could be obtained from the nitrate-free brine, by distillation or by solvent extraction using butanols or pentanols as extractants.

Filed: 1982-02-12
Abstract: The circuit of a gas-compression refrigerating unit in ice-cream making machines and/or ice-cream mixture pasteurizing machines has inserted therein a by-pass circuit controlled by one or more switching valves.
