Title: Refining process for removing antimony from lead bullion
Inventor: MEHTA JITESH R
IPC: C22B13/06
Filed: 1983-10-28
Granted: 1987-06-16
Abstract: ABSTRACT OF THE DISCLOSURE      "An Improved Refining Process for Removing Antimony from Lead Bullion"      An improved process for refining lead bullion containing antimony, in which the bullion is initially heated in a refining vessel to about 25°F (14°C) above the bullion melting point, and is thereafter kept molten primarily by exothermic process reactions.  The process includes the steps of melting the lead-antimony bullion, agitating the bullion, adding caustic soda and metallic sodium to form an antimony-rich skimmable refining dross comprising a sodium-antimony inter-metallic and separating the dross from the refined bullion.  Along with the antimony, other elements, such as arsenic, cadmium, copper, nickel, silver, sulfur, selenium, tellurium and zinc, if present in the bullion, are also removed in the dross by the sodium. The antimony-rich dross is accumulated for subsequent use.  The process further comprises a cleansing operation wherein sodium present in solution in the refined bullion is removed using cleansing agents. This refining process is performed at a temperature between 600°F (316°C) and 800°F (427°C). Through thecontrol of temperature, reagent addition and agitation, the process provides an environmentally nonpolluting and controlled process in which economies of materials, energy, time and labor are realized over conventional refining processes.

Abstract: Abstract The ceramic, porous filter body described in the claims is designed to overcome the lack of high temperature resist-ant thermoshock resistant and mechanical stable bodies for the filtration of metals, preferentially of iron and ferr-ous alloys. This filter body has a temperature resistance of 1600° C, a linear thermal coefficient of expansion of 3 - 7 x 10-6/°C and consists of hollow spheres based on min-imum one homogeneous distributed refractory material and another refractory material, which at high temperature by chemical reaction forms with the hollow spheres a solid refractory binding phase.     A process for the production of such a filter body is des-igned such, that the spheres of the refractory materials are mixed with a powderous binding phase, then formed to a porous body and then, by retention of the porous homogen-eous structure under formation of new refractory composi-tions by heat treatment are chemically reacted, at least in the contact areas of the spheres.

Abstract: ABSTRACT        A radio relay system for a fully-digitalized transmission network is disclosed.  In the system, a received auxiliary signal from a preceding station can be by-passed from the receiver to the transmitter via  a switching circuit provided in the auxiliary unit as long as no additional auxiliary signal is input to the equipment at the present station.  When a local auxiliary signal, for example, an order wire signal from the telephone equipment, is input, at the present station the switching circuit operatively disconnects the by-pass and switches in the additional auxiliary signal.  When a failure in the auxiliary unit or power supply occurs preventing an additional auxiliary signal from being input, the by-pass is switched on, thereby ensuring that auxiliary signals derived from the preceding station are passed to subsequent stations.

Abstract: ABSTRACT OF THE DISCLOSURE            For the purpose of controlling a thermal installation the flow of the process liquid through the heat exchanger (4) is achieved dependent upon two temperatures. One is the return temperature of the process liquid which, through the switching on or off of the circulation pump (8) is maintained at a constant value, the other is the room or out-side temperatures or the difference between these two temperatures whereby during the deviation of a predeterminable limiting value the pump is also switched on or off. Since the supply temperature from the boiler has a constant temperature, for a central heating system the same amount of heat is drawn from each unit of heating water and thus the measure of the pump flow is sufficient to determine the actual heat consumption. Thereby the fair division of heating costs for each tenant according to actual amount consumed is made possible.

Abstract: ABSTRACT OF THE DISCLOSURE      A programmable parts reorienter and feeder utilizes a fibre-optic array in a sensing head to determine an initial orientation of a part passing through a parts handling unit.  The sensing head is coupled to a microprocessor that has been programmed to recognize properly oriented as well as misoriented parts.  After determining the initial orientation of the part, the microprocessor will direct a reorienter device to either pass the part in the first orientation, orient the part to a preferred orientation or, in some cases, reject the part.  The microprocessor has been programmed with the ability to "learn" to distinguish multiple orientations of parts and in a run mode can then make part orientation determinations based on its "learned" information.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of automatically tracking a communication satellite by a parabolic antenna installed on a moving body such as ship, which can compensate for directional deviation caused not only by inclination of the body itself but also by its navigation, using a relatively simple and economical tracking system.  The antenna is adjusted previously in its elevation and azimuth so that a received signal level above a predetermined level is obtainable when the moving body is in its stationary state.  The method is characterized by a step of changing elevation and azimuth of the antenna within a predetermined range of variation, when the received signal level has lowered due to movement of the moving body, so as to trace a rectangular spiral on the celestial sphere by the axis of the antenna, until the received signal level exceeds the aforementioned predetermined level.
