Abstract: Lead-copper-sulphur charges (e.g., ores and concentrates) containing at least one of the elements Fe, Ag, Bi, Zn and Sn are treated pyrometallurgically to recover their metal values by a process comprising the steps of (a) smelting the charge to produce a slag phase containing at least about 10% Pb, a copper matte phase containing less than about 65% Cu, and a lead bullion phase; (b) separating the slag, matte and bullion phases formed in step (a); (c) reducing the molten slag separated in step (b) to decrease the lead content thereof to less than about 2% and form thereby a lead bullion phase; and (d) separating the slag and bullion phases formed in step (c). According to the process of the invention, the copper matte phase formed in step (a) is substantially free of iron; most of the silver is collected in step (a) in the copper matte and lead bullion phases; most of the bismuth is collected in the bullion phase of step (a); most of the iron, zinc, and tin are collected in the slag phase formed in step (a); the lead bullion phase formed in step (c) is substantially free of silver and bismuth; the slag phase formed in step (c) is substantially free of zinc and tin, and most of the zinc is contained in fly ashes.

Abstract: The invention relates to a method of removing dust deposits from heat-exchange surfaces where gas containing dust passes through a pipe or through a chamber (2) containing coolant tubes (3). Sound is generated in known manner from sirens (5) and particulate material (e.g. sand) is fed via a pipe (6) to mix with the gas containing the dust. The "sand" and dust are deposited on the tubes and are removed together by means of the sound generation more easily than would be the case if the "sand" were not being incorporated in the deposit. The grain size of the "sand" should be larger than that of the dust. <IMAGE>

Abstract: A cartridge-type filter, which is especially suitable for separating radioactive particles from reactor cooling water in nuclear power plants, comprises a filter housing 5 having an inwardly-facing flange 16 which is designed as a valve seat. A filter cartridge 10 is joined to an outwardly-facing ring 20 which is designed to sealingly cooperate with the flange 16 of the filter housing and freely suspend the cartridge in the filter housing. The filter housing 5 is divided by the ring 20 and the cartridge 10 into two separate spaces 22, 23. Contaminated fluid is led to the space 22 via a conduit 7 and filtered fluid is led away from the space 23 via a conduit 8. When used in a nuclear power plant, the conduits 7 and 8 are connected into the reactor cooling water circuit, and part of the reactor cooling water is conducted continuously through the filter circuit, which is parallel to the main water flow. <IMAGE>

Abstract: N- beta -(aminoethyl)- gamma -aminopropyltrimethoxysilane [NH2(CH2)2NH(CH2)3Si(OCH3)3] as a silane coupling agent and SiO(2-x)(ONa)x/2(OH)x/2 as colloidal silica are mixed into a radioactive liquid waste containing sodium sulfate as a main component, coming from a boiling water-type, nuclear power plant as an effluent. The resulting mixed radioactive liquid waste is supplied into a vessel provided with a rotating shaft with blades. The rotating shaft is revolved while heating the radioactive liquid waste in the vessel, thereby making the radioactive liquid waste into powder. The resulting powder containing the silane coupling agent and the colloidal silica is shaped into pellets by a pelletizer. The pellets having a low hygroscopicity and a high strength are obtained.

Abstract: An imbalance oscillation exciter having two imbalance weights arranged on each of two axially parallel or coaxial imbalance-weight carriers positively rotatably coupled with one another and rotating counter to each other or in the same direction. At least one of these imbalance-weight carriers comprises a shaft, whereby the imbalance-weight carriers are coupled with each other by a hub for continuous opposite rotation for the purpose of changing the phase position of the imbalance weights. A pin fixed on the shaft slidably engages in a hub groove. The pin is shiftable along a shaft slot extending at an incline to the hub groove by means of an adjustment member arranged coaxially in the shaft. The shaft has an axially parallel cylinder chamber open toward one of its end faces and in which the adjustment member is slidable with a piston extension sealed with respect thereto and facing the open side of the cylinder chamber. Pressure medium is supplied from the open side by way of a pressure medium chamber fixed in the housing and sealingly surrounding the pertaining shaft end and being applied against the mechanical back or reaction pressure of the piston extension. The rise or angle of inclination between the hub groove and the shaft slot, the direction of inclination, and the direction of rotation of the shaft may be so matched or adapted with respect to each other that the back or reaction pressure results from the torque transmitted by the pin.

Abstract: An analog signal is quantized over a range of quantizing levels, each level being associated with a digital signal, and wherein the digital signals which are associated with a predetermined band of the quantizing levels have zero disparity. In accordance with one aspect, those digital signals which are outside the aforementioned band and which have non-zero disparity are selected to represent corresponding quantizing levels in such a manner that positive and negative disparity signals are selected, alternately, to represent quantized analog signals which are disposed outside the predetermined band. In accordance with another aspect, those zero disparity digital signals having the smallest run-lengths are assigned to represent quantizing levels which are disposed substantially in the center of the quantizing range, and those zero disparity digital signals having progressively larger run-lengths are assigned to represent quantizing levels which are disposed progressively farther from the center of the range.

Abstract: A computer tomography device in which the detectors are asymmetrically arranged with respect to the connecting line between the X-ray source, the center of rotation of the source, and the detectors, produce. The detector device produces an incomplete profile of measuring values which are supplemented with "zeros" during processing in order to form a number of measuring values of a complete profile. In order to avoid artefacts which are produced by the acute transients between measuring values and "zeros", a number of measuring values adjoining the acute transients are projected around the center of rotation and multipled by a factor so that from the zeros a smoothly increasing series of adapted measuring values is obtained.

Abstract: Disclosed is a capacitance level measuring device comprised of a container whose level is to be measured and a probe inserted into and spaced from the container. The capacitance between the probe and container varies in relation to the level in the container. A capacitance measuring circuit determines the capacitance between the probe and container and thus indicates the level in the container. The integrity of the probe is verified by constructing the probe so as to include it in a series circuit, as well as the capacitance measuring circuit, and a lack of continuity in the probe is indicative of questionable probe integrity. The question as to the probe's integrity would indicate a questionable level indication from the capacitance measuring circuit. Various probe constructions are also disclosed.

Abstract: A vehicle hydraulic system wherein there is provided a primary pump coupled to a steering control valve through which steering of the vehicle is effected. A main priority valve is used to meter the flow of pressurized hydraulic fluid from the primary pump to either the steering control valve or an implement valve which is utilized to effect operation of auxiliary equipment, in accordance with the priority demands of the steering system. An auxiliary ground-drive pump provides a source of pressurized hydraulic fluid at all times the vehicle is in motion and is coupled to the steering control valve to provide a source of pressurized fluid when necessary or circulates the pressurized fluid to sump. The application of the output from the ground-drive pump is controlled by a secondary priority valve coupled to the output from the ground-drive pump to direct the output to the steering control valve or to sump. The main priority valve and secondary priority valve are both coupled to a common pressure source which applies a predetermined pressure differential to each of the valves for maintaining each of the respective valves in a desired position.
