Title: Apparatus for mixing an anaesthetic liquid with respiratory gas to be supplied to a patient.
IPC: A61M16/14
Filed: 1983-08-10
Abstract: A device for admixing liquid anesthetics into the respiratory gas to be supplied to a patient makes it possible to monitor the concentration, the flow of respiratory gas, the mixture ratio, and the flow of anesthetic. Errors may thus be indicated and safety is increased in medical practice. The device utilizes the phenomonen that during the evaporation of an anesthetic admixed with the respiratory gas, the temperature in the thermally insulated ambience of the mixing chamber drops by an amount depending on the ratio of the vaporized anesthetic to the respiratory gas, thus on the concentration. The temperatures are measured at the inlet of the mixing chamber by an inlet sensor and an intermediate sensor, and at the outlet of the mixing chamber by an outlet sensor. Upon heating the stream of respiratory gas by means of a heating element in the inlet portion, the breathing gas flow, its mixing ratio, and the flow of anesthetic can be measured, and thus the concentration can be determined from the necessary heating power input and the heating temperature. The measurement is effected by a heater control and evaluating circuit connected to the sensors and the heater, by which heater controlling measures are effected upon deviations from desired values.

Title: Process for leaching sulphide concentrates of the tetrahedrite type containing high concentrations of arsenic and antimony
IPC: C22B15/00
Filed: 1983-10-04
Abstract: A process for lixiviation of concentrates of copper sulphides of tetrahedral type containing high concentration of arsenic and antimony to recover copper and noble metals. The concentrates are repulped into an aqueous ferrous sulphate solution with an established and controlled solid-liquid ratio which is thereafter oxidized by an oxygen containing gas in a reactor, thereby oxidizing the sulphides to sulphates, precipitating iron as ferric arsenates and antimoniates and yielding a lixiviation pulp in which the solid phase contains the iron, antimony and arsenic as well as the insoluble sulphates of the non-ferrous metals, such as lead and noble metals, and the liquid phase containing the copper, free sulphuric acid and the soluble sulphates of non-ferrous metals, as well as zinc, cadmium, cobalt, etc. The metals contained therein are recovered, after solid-liquid separation by conventional method. Among them, the copper cementation with scrap iron from the lixiviation liquid is the preferable method, because it yields the necessary aqueous solution of ferrous sulphate for the lixiviation.
