Process for extracting zinc from silicate zinc ores, in which the comminuted ore is put in suspension in water, the aqueous or suspension is extracted with an alkyl phosphoric acid ester at a pH value of 1.4 to 3.5 and at a temperature of 20-90oC for a period of 30-300 minutes, the organic zinc-containing phase is separated from the aqueous solid-containing phase, the organic zinc-containing phase is treated with diluted sulphuric acid and the aqueous zinc sulphate solution is subjected to electrolysis to precipitate the zinc. According to this process, in the aqueous phase of the suspension during treatment of the suspension with an alkyl phosphoric acid ester, a dissolved silicic acid content of between 20 and 60 g SiO2/l is achieved by the addition of water or ores.

Dielectrically isolated regions of single crystal silicon are produced through the use of a specific melting process. In this process, a substrate having regions (e.g. 8 or 9) of single crystal silicon contacting regions of non-single crystal silicon (e.g. 4) that overlie a dielectric material (e.g. 6) are treated. In particular, the entire region(s) of non-single crystal silicon is melted utilizing primarily radiant energy. Cooling is then initiated and the molten silicon is converted into a region of single crystal material (e.g. area 30). Isolation is completed by removing the appropriate regions of single crystal silicon.

A method and apparatus for supplying dyes to a dyeing apparatus (30), dyes being selected to yield one of a group of colours. A plurality of tanks of dye (11-16) is provided, and a circuit leads from each tank to a selected one of a pair of valves (21, 22) that may either direct the dye to the dyeing apparatus (30) or direct the dye to be recirculated. The flow through each valve (21, 22) is metered so a particular rate of flow can be established. One group of the valves provides dye to the dyeing apparatus while another group of the valves (21, 22) recirculates dye to establish another color ready to be provided to the dyeing apparatus. The colors are defined in terms of the tanks (11-16) and rate of flow from the tanks, so a large group of colors can be defined and stored in a computer, and the computer can control valve position and pump speed to control the color produced by the dyeing apparatus.

Electro-hydraulic valve arrangements are useful in controlling a displacement control member of a variable displacement pump or motor. However, previous digital electro-hydraulic valves having brief pulse widths required special high speed solenoids to speed up the response time of the valve and resulted in increased cost of the valve. The subject digital electro-hydraulic valve arrangement (22) includes a pair of on/off solenoid actuated valves (32, 33) arranged in series so that a flow path is initiated by a first of the valves and is disrupted by the second valve. The response times of the valves are equal such that directing an electrical signal to the second valve during the response time of the first valve results in extremely brief pulse widths of the valve arrangement. Using two solenoid actuated valves in this manner permits the use of less costly solenoid valves to provide very brief pulse widths through the total valve arrangement.

Fumes disposal systems used with existing engines are complex, induce pollution and cause engine malfunction to occur. The present fumes disposal system overcomes these problems by utilizing the heat from the engine (10) exhaust to heat a tubular member (44) and cause excessive oil droplets, carbon particles and fumes to burn. The flow of exhaust from the engine (10) is used to dissipate the remaining crankcase (14) fumes insuring that any concentration of fumes are purged with the exhaust. Furthermore, the system controls the pressure within the crankcase (14) of the engine (10).
