Abstract: APPARATUS AND METHOD FOR CASTING LEAD INTO PLASTIC FOR SIDE TERMINAL BATTERIES                Abstract of the Disclosure Apparatus for injecting molten lead from a reservoir into a die mold cavity formed about an aperture in the wall of a plastic battery for casting lead-alloy battery terminal connectors.  Batteries are positioned adjacent the molten lead reservoir of the apparatus and mold portions move together to hold the battery containers in a clamp-like action.  Molten lead is die cast under pressure into the mold cavity in which a stainless steel threaded nut is positioned.  The lead is forced through a heated chamber into a portion of the mold which may be water cooled.  The mold is designed to allow venting of gases, thereby eliminating porosity; and the appara-tus is designed to provide casting which is free of jagged pro-jections in the sprue hole.  The aperture in the battery wall is surrounded by a series of plastic annular rings extending outward from the battery wall but being a part thereof.  The molten lead surrounds the annular rings and fills the spaces therebetween when it is injected into the cavity.  The heat from the molten lead partially melts the plastic rings thereby forming a good seal between the casting and the battery wall.

Abstract: ABSTRACT    In cardiac signal processing apparatus, there is provided improved means for suppressing pacer signal artifacts, including both the discharge pulse and the recharge waveform (tail) of such artifact.  Rate-limiting circuitry is used to substantially suppress the discharge pulse.  However additional circuitry responsive to the detection of a pacer pulse is operative to obtain a measure of the electrical  discharge of the discharge portion of the respective pacer pulse and to use such measure to generate a tail suppression signal which, when added to the ori-ginal signal, substantially cancels the original pacer tail.    A feed-back loop is opened by the rate-limiter when a pacer pulse occurs and in turn permits a large signal to be imposed of a threshold-level-type pacer pulse detector for connecting the large signal (pacer pulse) to a capacitor during the discharge portion of the pacer pulse.  The capacitor being to discharge shortly after the pacer pulse's discharge portion with a polarity and time constant selected to substantially cancel (when summed) the pacer tail.

Abstract: ABSTRACT           A machine for the coating of a strip material sub-strate, flat stock or the like has a plurality of spray coating guns applying coating material to the substrate.  A sloping ceiling and nozzle support assembly causes any coat-ing material deposited thereon to flow along these surfaces to the side of the substrate rather than collecting above the substrate and dripping on the substrate and degrading the desired finish.  In a rotary coater, the sloping ceiling and nozzle support assembly can be combined into one rotating structure wherein centrifugal force arising from the rotation of the structure causes any coating material deposited on it to travel to its outer rotating edge where it is thrown clear of the substrate.  Troughs over the entrance and exit openings of the coater collect coating material which would otherwise drip onto t he substrate form above the openings and carry such coating material clear of the substrate.

Abstract: HYBRID FLYWHEEL/COMPRESSED-FLUID PROPULSION SYSTEM           FOR NONSTATIONARY APPLICATIONS     Abstract of the Disclosure The adaption of a compressed-fluid such as compressed-air) powered turbine in conjunction with the use of a flywheel as a hybrid propulsion system for nonstationary applications, such as vehicle drive, is shown and its practicality demonstrated.  This propulsion system requires a nonpolluting fluid, such as air, and a source of mechanical or electrical energy to compress said fluid and energize said flywheel, both of which act as energy storage media.  An expander/compressor unit, such as a turbine, is used for converting the stored energy of said compressed-fluid into shaft power by expanding said fluid, and recovering the braking energy during vehicle deceleration by compressing and storing the atmospheric air (if air is used).  Said flywheel is used not only for providing peak powers necessary for vehicle acceleration but also for recovering the braking energy during vehicle deceleration and refilling said compressed-fluid in an emergency.  The propulsion system can use the unlimited supply of air as the primary energy-storage medium and said flywheel as the secondary energy-storage medium.  The propulsion system is not only regenerative but also quick-recharging; it, therefore, has high energy-efficiencies and broad applications.

Abstract: ABSTRACT OF THE DISCLOSURE     A process for purifying gases containing hydrogen sulfide and/or hydrogen cyanide is provided wherein said gases are contacted with an absorbing solution containing naphthols or their salts as a catalyst having a nitroso group at .alpha.- position or .beta.- position, acidic group(s) and a standard redox potential in the range of 0.4 V to 0.7 V.         Hydrogen sulfide and/or hydrogen cyanide are removed by converting the former mainly into thiosulfuric acid and the latter mainly into thiocyanic acid.  According to this process, no trouble is caused by sulfur deposit as in conventional methods.  The scale of the purification appa-ratus is smaller, and the amount of catalyst required for purification is reduced.  Further by pretreating the absor-bing solution, this process becomes even more advantageous.
