Abstract: ABSTRACT OF THE DISCLOSURE     A method for the recovery of metal values from a solution by means of a cementation reaction in an oscillating container wherein the resulting cementate is converted by pyrometallurgical methods into molten metal and slag.  In accordance with the present invention, at least a portion of the slag in particulate form is directed back into the oscilla-tion reaction to serve as an agitation medium.  This method en-ables to prevent losses of residual metal content remaining in the slag, and to reduce the additional costs and expenditures for the comminution, grinding and disintegration of the slag.

Abstract: ABSTRACT OF THE DISCLOSURE A heat sink for cooling electrical components with cooling gas, wherein the cooling gas flows through the heat sink in closed cooling pas-sages from entrance openings to exit openings and the cross-sections of the passages increase from the entrance openings to the exit openings.  The heat sink is built up, for example, of cooling fins arranged between two base surfaces.  The shape of the cooling fins is such that their thickness dec-reases from the entrance openings to the exit openings, while the height of the cooling canals increases in the same direction.  Alternatively, the cooling fins may diverge, fan-like, towards the exit openings.  In one em-bodiment, the heat sink is made as a block having holes serving as cooling ducts, and the diameter of the holes increases toward the exit openings. The increasing cross-section of the cooling passages in the heat sink results in expansion of the cooling gas as it flows, and the temperature of the cooling gas decreases in accordance with the pressure conditions and, thus, more heat is removed from the heat sink.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and an apparatus for installing a gasket in the peripheral wall of an opening in a masonry wall, is disclosed.  The gasket is positioned in a recess formed in the outer periphery of a flexible, resilient cylindrical mold.  A rigid cylindrical member, having an outside diameter equal to the inside diameter of the flexible mold and a flange at one end, is inserted within the flexible mold to support the mold.  The mold supporting member is secured to the external wall of the concrete form and tightened so as to compress one end of the flexible mold against said wall of the form and form a seal with such wall.  The inner wall of the form is installed in sealing engagement with the other end of the mold.  The space between the walls of the form is filled with concrete, so as to embed the entering portion of the gasket in the concrete.  When the concrete is set, the form and the mold supporting member are removed and, finally, the flexible mold withdrawn so as to leave the sealing portion of the gasket which is not embedded in the concrete projecting into the space intended to receive a pipe.

Abstract: QUICK RELEASE FOR GYRATORY                 CRUSHER CONCAVE     Abstract of the Disclosure In a crusher having a gyratory conical crushing head that cooperates with an annular bowl, the bowl has a threaded connection with a frame member, to be adjustable up and down by rotation.  A clamping ring, acting like a jam nut, also has a threaded connection with the frame member and is so connected with the bowl as to be constrained to rotate with it; but normally the bowl and clamping ring are biased towards one another under clamping force, to prevent bowl rotation.  To release the bowl for rotation, pressurized air is injected between the bowl and the clamping ring, acting directly on them to overcome clamping force and being introduced via the helical passage defined by the threaded connection between clamping ring and frame member.  Seals between the bowl and clamping ring, and between the bowl and frame member, prevent escape of the air.

Abstract: KEYBOARD VERIFICATION SYSTEM  ABSTRACT OF THE DISCLOSURE A capacitive keyboard veritification system is disclosed wherein key movement is verified with a high degree of accuracy in a manner largely immune to ambient noise or other electronic or electromagnetic interference. A pulse signal, in the form of a train of pulses, is periodically applied across the capacitor associated with each key.  The signal coupled through the capacitor is reconstructed only if it exceeds a predetermined reference level.  A test, which depends on the previously verified key state, is made to determine the existing key state.  The test for the active key state is conditioned on multiple true comparisons of a reconstructed signal with the originally applied signal throughout the duration of the test.  The test for the inactive key state is conditioned on the absence of a reconstructed signal throughout the test.  In both instances the newly indicated key state is compared with the state to which the key is assumed to have changed from its previously verified state.  If the test fails, the key is considered to have remained in its previously verified state.          Immunity to noise is enhanced by making the pulse signal a pseudo-random signal which is successively applied across the key-associated capacitors in a timing sequence out of synchronism with the generation of the pulse signal.  The system disclosed avoids the requirements for massive shielding, for selective routing of conductors, or for the assignment of special, physical key locations in the electronic scanning sequence, while providing fully verified key actuation at reduced overall system cost.

Abstract: 2195-24a ABSTRACT     A mechanism which applies ink to selected portions of a running paper web has an imprinting roller and a counterroller.       The web travels through the nip of these rollers, and the protuberances at the periphery of the imprinting roller receive ink from a trough by way of a withdrawing roller which dips into the supply of ink in the trough and a  transfer roller which delivers a film of ink from the periphery of the withdrawing roller to the protuberances of the imprinting roller.  At least the imprinting roller is hollow and confines a dynamic damping system whose natural oscillation frequency is attuned to that of the imprinting roller so that the system damps the oscillations of the imprinting roller when the mechanism is in use whereby the protuberances invariably transfer ink to selected portions of the running web.  Additional damping system or systems can be installed in the counterroller, withdrawing roller and/or transfer roller.
