Abstract: A METHOD FOR WORKING-UP COMPLEX SULPHIDIC ORE CONCENTRATES           ABSTRACT OF THE DISCLOSURE            A method for recovering the metal values of polymetallic sulphidic ore concentrates containing lead and/or gold and other precious metals and at least one copper, nickel, cobalt, zinc, uranium, molybdenum, iron and silver.  The concentrates is treated by (a) roasting under magnetite-yielding conditions, (b) sulphating in an oxidizing environment, (c) leaching in water or an aqueous solution of sulphuric acid and (d) treating the leaching residue in a solution of chloride of an alkali or earth metal.  The leaching of stage (d) may be carried out while supplying chlorine gas to recover gold or platinum from the concentrate.  Alternatively, the leaching residue may be treated by smelting the lead residue while slagging the iron content to recover lead bullion containing precious metal.

Abstract: ABSTRACT          Injection   apparatus   suitable   for   supplying in-mold  thermoset  coating  material  into  a  compression molding  tool  is provided,  which  injection  apparatus comprises  a  housing  (10)  the  forward  end  of  which comprises an outlet nozzle (11) and an outlet channel (12) extending through the outlet nozzle, the forward terminus of the outlet channel being an outlet port  (13).   First and second material supply channels  (14  and 15)  extend within  the  housing  from  first and  second  supply  inlet ports  (16  and  17)  in  the  housing,  respectively,  to  a single  common  junction  with  the  outlet  channel.   A shut-off rod (26) is slideably disposed within the outlet channel, being adapted to provide a sealing closure of the outlet  port  in  a  first,  forward  position  and  being retractable from the forward position to a second position in  the  outlet  channel  rearward of  the  junction of  the material supply channels with the outlet channel.  In both the forward and retracted position, the shut-off rod forms a sealing engagement with the outlet channel rearward of the junction of the two material supply channels with the outlet  channel.   Significantly,  the  first  and  second material supply channels are in communication with each other  via  only  a  single  flow-path,  at  least  when  the shut-off rod is in the forward position.

Abstract: METHOD AND APPARATUS FOR SHAPING    A DISTAL FEMORAL SURFACE                         Abstract The present invention provides a method and apparatus for preparing the distal surface of a femur to receive a distal femoral prosthesis employing an intramedullary reamer which is used to internally locate the central long axis of the femur, an intramedullary alignment guide which is inserted into the space left in the intramedullary canal upon removal of the reamer and at least one femoral surface modifying instrument which cooperatively engages with a guide handle attached to the intramedullary alignment guide to accomplish the shaping of the distal femoral surface.  The intramedullary alignment guide has a rod portion extending into the femoral intramedullary canal whose central long axis corresponds with the central long axis of the femur.  The guide handle is attached to that rod portion at a preselected angle such that the shaping instruments fixed thereto assume the proper alignment with respect to the central long axis of the femur such that the distal femoral surface is shaped relative to that axis in a simple and accurate manner.

Abstract: ABSTRACT OF THE DISCLOSURE      An improved apparatus and method is disclosed for use in a system for growing a hollow tubular body of crystalline material by growing the body from the end of a die member, whereby the hollow tubular body can be cut lengthwise along predetermined lines of the body to provide separate crystalline bodies.  The apparatus comprises means (preferably in the form of notches provided in the die end of the die member from which the hollow body is grown) for concentrating stress in the hollow tubular body along the predeter-mined lines as the body is pulled from the die end. The method comprises the steps of (a) growing the tube from a die end of a die member so that stress is con-centrated in the tube along predetermined lines as the tube is grown; and (b) cutting the tube along the pre-determined lines so as to separate the hollow tube into the plurality of bodies of the crystalline material.

Abstract: Abstract of the Disclosure A carburetor for small motors has a housing with a carburetor bore wherein air and fuel are mixed to an air fuel mixture.  The fuel enters the carburetor bore through fuel jets.  A throttle valve is pivotal mounted in the carburetor bore by means of which the fuel-air mixture quantity is adjusted in dependence upon the operating condition of the engine.  The throttle valve and the inner wall surface of the carburetor bore conjointly define an air gap in the idling position.  An idling fuel outlet jet communicates with the carburetor bore in the region of this air gap and is connected to the control chamber containing the fuel.  The idling fuel outlet jet together with a ventilation bore communicate with an emulsion chamber of the control compartment.  Further, an idling control part is provided which is movable into the air gap whereby an outlet opening of the ventilation bore communicating with the emulsion chamber is passed over.  In this way, the ratio of fuel to air in the emulsion chamber can be adapted to the air requirements when flowing into the carburetor bore from the outlet jet.  By means of a change of the free cross-sectional opining of the ventilation jet occurring simultaneously with the entry of the control part into the air gap, the air to fuel ratio remains constant so that a subsequent adjustment of the components of the mixture is unnecessary.

Abstract: ADAPTIVE SIGNAL PROCESSOR FOR    INTERFERENCE CANCELLATION     ABSTRACT OF THE DISCLOSURE       The present invention relates to an adaptive signal processor for reducing interference in ranging and communication systems resulting from jamming or multipath reception.  More particularly, an optical signal processor is provided in which a first time correlation is performed between the receive signal derived from a direction antenna and an interference signal derived from one or more auxiliary omni-directional antennas in an acousto-optical device to obtain one or more corresponding weighting functions stored as a function of signal delay.  The auxiliary signal is then correlated in a spatial correlation process in which the auxiliary signals are delayed and multiplied with the weights and the result spatially integrated to derive the predicted interference.  The predicted interference is then subtracted from the main signal in an adaptive feedback loop wherein the pre-dicted signal is made to approach equality with the interference.  The system achieves good cancellation by correcting for multiple arrival times and by retaining the phase and amplitude information of the original carriers throughout the optical process.
