Abstract: ABSTRACT OF THE DISCLOSURE:           A process for controlled slow cooling of non-ferrous smelting slags, such as copper slags, for the recovery of the non-ferrous metals contained therein by subsequent crushing, mil-ling and flotation operations is disclosed.  The process compri-ses the steps of pouring the molten slag into a ladle, allowing the slag to slowly cool and solidify in the ladle at least to the point where a shell is formed which is strong enough to withstand dumping from the ladle, dumping the slag from the la-dle in a single piece, allowing the dumped slag to cool until its center is substantially solidified, and breaking the dumped slag in small pieces for further cooling, crushing, milling and flo-tation operations.  Alternatively, the top of the slag in the ladle may be water cooled while the slag is allowed to slowly cool in the ladle until its center is substantially solidified.          The slag is then dumped and subsequently broken in small pieces.

Abstract: SEMI-AUTOMATIC HANKING APPARATUS     Abstract An apparatus for forming a length of elongate flexible material into a hank containing a selectable number of loops.  The material is wrapped around a pair of post members which are mounted on a rotatable base member which in turn is drivingly connectable to a continuously-running electric motor via an electronically-controlled clutch and brake assembly.  When the clutch is engaged the brake is released, thereby permitting the base member to be rotated by the motor, and when the clutch is released the brake is engaged, thereby accurately stopping the base member at a predetermined angular position.  The electronic control circuitry activates the clutch and releases the brake when an operator depresses a foot switch, and releases the clutch and activates the brake upon receiving a predetermined number of signals representing revolutions of the rotating base member from a magnetic sensor positioned proximate the base member and responsive to the passage therepast of a ferrite element mounted on the base member.  Operator-adjustable controls associated with the electronic control circuitry permit the base member to be stopped after any predetermined number of revolutions and at different predetermined angular positions.          To facilitate the withdrawal of the finished hank after the base member has been stopped, the two posts around which the hank is wrapped are movable laterally toward each other, but are spring-biased to return to their respective outward-spaced position.

Abstract: ABSTRACT OF THE DISCLOSURE   There is not known a rapid test for the determination of procoagul-ants in the blood.  The presence of procoagulants is an indication of thrombos-is or a prethrombosis condition.  The present invention overcomes this draw-back by providing a method of measuring serum coagulability in a patient com-prising the steps of adding heparin in different amounts to aliquots of serum from a patient, adding each of the resultant heparin-serum solutions to a separate tube containing thrombin solution, reacting a portion of each of the resultant thrombin-heparin-serum solutions with normal plasma solution to determine whether clotting occurs, and in the event clotting occurs, deter-mining the clotting time, all steps being carried out under standardized conditions, thereby making it possible to compare the measured clotting times with clotting time ranges obtained under similar conditions with serum from healthy unmedicated individuals and from known thrombotic individuals, and to establish whether the measured clotting times fall within a first normal range corresponding to normal, unmedicated individuals, a second low range corresponding to thrombotic individuals, or third and fourth ranges intermedi-ate said normal and low ranges and corresponding to individuals of increasing coagulability, a low clotting time correlating with high serum coagulability.

Abstract: Abstract of the Disclosure A closed-loop mixture control system for an internal combustion engine comprises an exhaust composition sensor generating an output whose waveform is nonlinear and substantially symmetrical with respect to a pre-determined air-fuel ratio, a differential amplifier connected to the composition sensor for comparison with a reference voltage which is variable in accordance with the engine operating parameters, and an integral controller for integrating the output from the dif-ferential amplifier.  The differential amplifier output is normally symmetrical with respect to a predetermined value of the reference voltage to control the air-fuel ratio at a desired value that corresponds to the maximum conversion efficiency of a catalytic converter.  Under transient conditions, the reference voltage is varied so that the differential amplifier generates an un-symmetrical voltage which, when integrated, produces a bias voltage that shifts the air-fuel ratio to a value preferable for the transient engine operating conditions.

Abstract: ABSTRACT OF THE DISCLOSURE This  invention relates to a liquid level measuring and recording apparatus which includes a recording stylus or pencil and a means for retaining a record such as marking paper.  The stylus is connected to a float means which follows the level of the liquid and drives the stylus along the width of the paper in one direction when the level is rising and in the other direction when the level is falling.  In addition, either the stylus or the paper are connected to rotating means which rotate in one direction only and which are also driven by the up and down movement of the float.  As the rotating means rotates in one direction only, the stylus will produce a straight line along the width of the paper when the float is moving in the non-rotating direction, and a straight line at an angle to the first line, when the float is moving  in the rotating direction.  Preferably, the straight line is produced when the float is moving in an upward direction, and the straight line at an angle to the first line is produced when the float is moving in a downward direction.  The rotating means can comprise a slip-clutch.
