Abstract: ABSTRACT OF THE DISCLOSURE         A combination reduction, distillation, reducing metal  recovery  furnace  and  process  of using  the same comprising a pair of vertically displaced vessels in fluid communication wherein the upper vessel contains a perfor-ated inner liner and means to at least periodically charge the top of the vessel with a metal salt to be reduced and a reducing metal, and wherein the lower vessel has a means to periodically withdraw the molten reducing metal  salt produced by the redox reaction occurring within the fur-nace.  By initially charging the furnace with sufficient reducing metal salt to establish a liquid level to provide a liquid seal above the bottom of the inner liner and by maintaining  this  level  during the  redox  reaction,  the inner liner can be filled with solid phase reduced metal produced by the reaction (and no reduced metal is produced outside of the liner).  Upon completion, the molten reduc-ing metal  salt is drained from the  furnace,  the  lower vessel  is  cooled  and  the unreacted reducing metal  is distilled from the upper vessel and collected in the lower vessel.  The unreacted reducing metal can be recycled to the subsequent run by loading a quantity of reducing metal salt into upper vessel and melting it.  The reducing metal in the lower vessel is then melted and allowed to float up into the inner liner of the upper vessel where it provides a portion of the reducing metal required for the subsequent run.  Such a process and apparatus is useful in producing large quantities of high purity metals such as Zr, Ti, Hf and the like.

Abstract: i.                     ABSTRACT         A unique, surgical stapling instrument is attained by incorporating staple guiding and supporting cam means positioned in active, cooperating relationship to the legs of the staple during its formation.  In this way, unwanted angular pitching or wobbling of the staple during formation is substantially eliminated.  In the preferred embodiment, staple tip positioning means are also provided in cooperative association with the staple being formed to assure controlled movement of the staple into the desired forming orientation, thereby substantially preventing jamming or double staple formation.  In addition, the staple forming plate incorporates a unique construction which assures complete staple formation prior to exiting through the cooperating housing portal, while also providing a staple tip entry zone, allowing the tips of the next staple to be formed to be positioned in the desired plane prior to the crown portion thereof.  The surgical stapling instrument of the present invention also preferably incorporates two independent handle portions, one of which is slidingly, interlockingly engaged with the housing of the stapling instrument in order to assure a securely interlocked surgical stapling instrument, while also allowing the housing to be formed of transparent material, while the ii. handles comprise opaque material  In addition, alternate handle configurations are interchangeably mountable to the housing.

Abstract: ABSTRACT OF THE DISCLOSURE           A transceiver is provided with both voltage and current coupling to a three phase transmission line system.          Each phase conductor is coupled to a common point which is connected  in  signal  communication  with  an  input  to  a receiver.  Another input of the receiver is coupled to the neutral conductor of the power line system by an H-field coupler.  A  signal coupling unit is associated with the voltage couplers between the common connection point and the first receiver input.  The receiver is provided with the capability of comparing the voltage signal with the current  signal  and  selecting  the  stronger  of  the two.          Therefore, the transceiver of the present invention is less adversely  affected  by standing wave problems  since the voltage and current signals are out of phase and voltage nodes-are associated with current antinodes and vice versa. Therefore, regardless of the location along the standing wave  that  the  transceiver  is  located,  the best  signal available will be used for demodulation purposes.

Abstract: ABSTRACT               The spark plug ignition advance control for a multiple cylinder internal combustion engine has a spark ignition circuit associated with each cylinder.  The circuit includes an SCR trigger operative to cause the ignition spark.  A pulse generator is associated with each cylinder and puts out a control pulse to a latch gate outputing to the ignition circuit.   The gate responds to a control pulse to latch in an enabled state. A frequency multiplier receives control pulses from the pulse generator and provides 360 reference pulses for each revolution of the engine.  A counter responds to the control pulse to count said reference pulses.  A ROM storing ignition timing data corresponding to throttle position.  A throttle position sensor provides a control voltage which is applied to an A/D converter which outputs an address in the ROM and the ROM puts out the number of degrees by which the base throttle advance is to be modified and sets the counter to count said reference pulses to said number.  The counter subtracts the counts (degrees) from the basic (maximum) advance and outputs a control signal (firing pulse) when the correct advance is reached.  The firing pulse is applied to the latch gate which causes the SCR trigger to operate.  The firing pulse also resets the system to start again for the next cylinder.

Granted: 1990-04-03
Abstract: ABSTRACT          PROCESS FOR THE SEPARATION OF METALS FROM AQUEOUS MEDIA         Paramagnetic metals are separated from aqueous media containing them in low concentration by first fixing the metals on bacterial yeast or other cells so as to render the cells magnetic, and then recovering the cells by a high gradient magnetic separation technique.  The metal and the cells are contacted in the presence of a compound which is converted by the cells into a product which interacts with the metal and causes it to become bound to the cells.  The process is particularly useful for removing low concentrations of highly toxic metals, e.g. uranium, from industrial effluents containing them.
