Abstract: Abstract of the Disclosure The recovery of non-ferrous transition metals such as copper and nickel from acidic hydrometallurgical leach liquors with a s-picolylamine chelate exchange resin is improved by the in situ reduction of Fe+3 present in the leach liquor with a water soluble reducing agent during the resin loading cycle.  The chelate resin functions not only as a selective sorbent for the desired metal values, but also as a catalyst for the in situ reduction of Fe+3 to Fe+2.  A suitable reducing agent such as SO2 or HCHO is fed into the chelate resin column with the leach liquor,  When the loading cycle is completed, regeneration with sulfuric acid gives an enriched eluent with a high non-ferrous metal:Fe ratio.          For example, using SO2 with a copper leach liquor feed, subsequent regeneration at about 70°C. gives better than 90 percent recovery of the copper as a highly enriched copper sulfate solution with a Cu:Fe ratio of about 10,000.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus and method for measuring operator-selected dimensions of a sample workpiece or part in an inspection field and, in one embodiment of the invention, for subsequently and automatically measuring the same dimensions of parts subsequently positioned in the inspection field.  In accordance with one aspect of the invention, there is provided a means for optically scanning a sample part in the inspection field and means for effecting display of the part in the inspec-tion field.  An operator-positionable cursor is provided for selecting and displaying the coordinates of reference points in the inspection field.  Means are provided for storing an operator-selected reference point and, also for storing an operator-selected pattern.  The operator-selected pattern is scanned with respect to the part, the pattern originating from the operator-selected reference points.  Means are also provided for determining at least one dimension of the part, the dimension being determined as a function of the inter-sections of the pattern with the part. In one form of the invention, means are provided for optically scanning parts subsequently positioned in the inspection field.  The scan pattern used in scanning the subsequent parts is determined by the stored reference point and the stored pattern.  Further means are provided for determining at least one dimension of each subsequent part in the inspection field, the dimension being determined as a function  of the intersections of the scan pattern with the subsequent part.  In this manner, the same dimension of all subsequent parts is automatically measured.  In the preferred embodiment of the invention, means are provided for storing an operator-selected tolerance with respect to the at least one dimension of the sample part and for determining whether the at least one dimension of the subsequent part is within the operator-selected tolerance.  In this embodiment, means are also provided for determining the centroid and relative rotational orientation in the inspection field of the sample part and the subsequent part, and for effecting a coordinate transformation as between the parts such that different positions or orientations of subsequent parts in the inspection field are accounted for.

Abstract: ABSTRACT OF THE DISCLOSURE     A steering gear of the push rod kind suitable for motor vehicles is restrained from exhibiting rotation relative to the housing member during its longitudinal displacement by a track follower.  The follower, which is on one of the members, slidably engages and follows a longitudinally extending track on the other member.  At least a control part length of the track extends in a direction other than parallel to the direction  in which the push rod is longitudinally displaced.  During longitudinal displacement of the push rod and while the follower is moving along the control part, the push rod exhibits controlled rotation relative to the housing and thereby affects a change in the steering ratio between the longitudinal displacement of the push rod and rotation of the nut.

Abstract: ABSTRACT           A gyrating cone-shaped head cooperates with a stationary bowl support to crush rock or the like admitted into the crusher.  The gyrating action of the head is accompli-shed by an off-set shaft arrangement for the head driven by a rotatable eccentric member.  Input drive for the crusher rotatably operates the eccentric member through an independ-ent coupler for improved gear alignment, operation and main-tenance.  The head has gyrating support on a dished bearing surface of the main frame, and hydrostatic pressure is ad-mitted between the head and the frame support to minimize wear.  Also, a fluid lift is provided for portions of the drive apparatus to support such parts and eliminate thrust loading caused by the weight of such parts on a radial roller bearing, thereby prolonging the useful life of the bearing. An improved seal is provided between the head and the main frame and is of a structure to remain intact and to operate effectively under all normal operating conditions of the crusher.  Fluid operated apparatus is used to provide a pressure hold-down for the bowl and also fluid operated appara-tus is provided for adjusting the bowl rotatably and for lock-ing the bowl securely.

Abstract: Abstract of the Disclosure An electrohydraulic control system and method are disclosed for operating valves controlling the admission of steam to a steam turbine.  The system includes a mode transfer unit for effecting a transfer between a full arc mode of valve operation to a partial arc mode of operation such that the temperature of the steam turbine varies in a controlled manner, thus permitting control of turbine stresses.  Apparatus is described for generating mode flow signals, combining the signals using time ratio switching such that during a mode transfer the signals vary linearly with an admission reference factor characteristic of each mode, and generating valve lift signals from a combined flow signal using multi-slope, piecewise linear approximations to the flow-lift characteristics of the full arc mode of valve operation.  The system permits mode transfers wherein total steam flow is held substantially constant and first stage turbine temperature is caused to vary linearly with admission reference factor.

Abstract: Abstract of the Disclosure This invention is directed to a method for producing agglomerates of unit, or near unit, fibrils of chrysotile asbestos from crude chrysotile asbestos.  It comprises forming a stable gel structure of unit, or near unit, fibrils of asbestos by mixing the crude asbestos with an aqueous dispersion  of an asbestos dispersing agent to disperse the fibrils to form the stable gel structure.  The gel structure dispersion is diluted with water in a first dilution step to form a readily pourable dispersion without diluting the concentration of the asbestos dispersing agent to a level where it is insufficient to maintain the asbestos fibrils in a dispersed state.  The dispersion is rapidly diluted with water in a second dilution step sufficient to reduce the concentration of the asbestos dispersing agent to a level where it is insufficient to maintain the dispersion such that the dispersion of the fibrils collapses and agglomerates of the fibrils are formed.
