Abstract: Abstract A one-step, guaiac reagent based, diagnostic aid for determining the presence of occult blood in an aqueous system includes an absorbent carrier having absorbed thereon guaiac in a water soluble polymer matrix.  A dry powdered oxidizing agent, such as a monopersulfate compound, is placed in contact with the carrier.  The oxidizing agent is capable of oxidizing guaiac to a blue dye in the presence of water and hemoglobin.  The oxidizing agent in the absence of water is substantially nonreactive with the guaiac in the carrier.  In a second embodiment, the diagnostic aid contains a micron-sized silica gel into which a guaiac solution has been adsorbed.  The guaiac-containing carrier is contacted with a dry, particulate, oxidizing agent, such as a monoper-sulfate compound, to form a single powdered reagent composition, which can, for example, be packaged in a water-pervious sandwich.  When the diagnostic aid is contacted with water, the oxidizing agent is activated to produce hydrogen peroxide, which in the presence of occult blood will oxidize the guaiac to a brilliant blue reaction product.

Abstract: APPARATUS & METHOD FOR PLATING METALLIC STRIP  ABSTRACT     Method and apparatus for electrogalvanizing one or both sides of a steel workpiece are disclosed.  A series of insoluble apertured plating anodes are posi-tioned in spaced relation to the workpiece.  When one side is to be plated one or more anodes are preferably mounted above the strip and when both sides are plated, anodes are mounted both above and below the strip. Solution is pumped through the holes in the anodes to momentarily contact the workpiece and they fall into a sump to be recirculated.  A potential difference between the anode or anodes and the workpiece causes current flow through the electrolyte solution to elec-troplate the workpiece.  Solution collected by the sump is directed to a reaction station for replenish-ment of the zinc metal ion.  The solution is then filtered back to a main reservoir tank from which it is again pumped to the plating anodes.

Abstract: ABSTRACT OF THE DISCLOSURE          A security installation at one Site comprises remote sensors which detect intrusion, fire etc. and transmit corresponding signals by radio to a master station. Similar installations are provided at other Sites. The sensors of each Site precede their data signals with an access code which is particular to that Site and prevents their signals being received by the master station of any adjacent Site within radio range. When a new installation is to be installed at a new, adjacent Site, an arbitrary value is initially selected for its access code and the master station there transmits a special code to all adjacent Sites.  In response to this special code, the master station in each such adjacent Site transmits its own access code back to the new installation, where it is compared in value with the arbitrarily selected access code. The latter is automatically changed until it becomes different from that of any and all adjacent Sites. The remote sensors of the new installation are then set to this value.

Abstract: Title of the Invention CONTROLLED BONDING WIRE BALL FORMATION Abstract of the Disclosure Apparatus and method are described for rapid ball formation at the end of lead wire retained in the capillary wire holding tool of a ball bonding machine.  A circuit is coupled between the cover gas shroud and lead wire for establishing controlled electrical discharge between the end of the bonding wire and the shroud, for melting and forming a ball.  The circuit includes a DC power supply for delivering a positive polarity to the shroud and negative polarity to the lead wire for drawing a discharge of electrons from the end of the lead wire to the shroud.  A capacitor is coupled in series with the DC power supply for receiving the electrical discharge.  An impedance is also coupled in series for limiting the electrical discharge current.  Charging of the capacitor limits and shapes the electrical arc discharge to a controlled pulse profile of short duration for rapid ball formation.  An electronic gate is also used to control pulse duration.  The rapid and controlled ball formation avoids necking or thinning of the lead wire which often occurs at the stem above the bonding ball.

Abstract: TITLE OF THE INVENTION         IDLING RPM FEEDBACK CONTROL METHOD      INTERNAL COMBUSTION ENGINES           ABSTRACT OF THE DISCLOSURE      A method of controlling a control valve that regulates the quantity of supplementary air being supplied to an internal combustion engine, in a feedback manner responsive to the difference between actual engine rpm and desired idling rpm at idling of the engine.          During deceleration of the engine, the control valve is controlled so as to supply the engine with supplementary air at a volumetric flow rate dependent upon a detected value of ambient atmospheric pressure, after the engine has been determined to be in a predetermined operating condition and until the above feedback control is initiated.  Preferably, the volumetric flow rate of the supplementary air quantity is set to larger values as the detected value of the atmospheric pressure decreases.          The engine is determined to be in the above predetermined operating condition when at least one of conditions is satisfied that the actual engine rpm is smaller than a predetermined value larger than the desired idling rpm, and that the output shaft of the engine is not in engagement with a driven shaft driven by the engine.
