Abstract: ABSTRACT OF THE DISCLOSURE     An interlock system for use on a conventional gasoline dispensing nozzle with an automatic shut-off system is disclosed.  The interlock system includes a valve mounted in the discharge spout and connected to the vent tube so that when the valve is in its open position, the vent is open to the inside of the discharge spout.  The valve actuation system is designed so that when the nozzle is not properly inserted into the vehicle fillpipe, the valve obtains an open position so that in the event dispensing of gasoline is attempted, the vacuum created in the vent tube by the venturi in the automatic shut-off system causes gasoline which flows down the discharge spout to be drawn into the vent tube, thereby causing the automatic shut-off system to disable the nozzle.  The valve actuation system is also designed to act in response to the weight of the nozzle resting on the fillpipe and to provide the latching capability for the nozzle.                             - i -

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for making metal castings and particularly nodular iron castings.  The castings are made in molds, each having a chamber in the upper portions of the mold, the chamber being connected by gating passages to the casting cavities.  In the manufacture of nodular iron castings, a nodu-larizing agent as placed in the chamber.  The chamber is open at the top and the molten metal flows from the chamber into the gating passages of the mold through openings that are disposed above the floor of the chamber.  During the pouring operation the upper surface of the mold, including the open top of the chamber, is closed by a refractory sealing member having a pas-sage through which the molten metal can flow.  This passage is connected to a launder or the like to which molten metal is sup-plied by a furnace.  At the end of the launder there is a ver-tical conduit that extends downwardly and provides a closed conduit for the vertical flow of metal from the launder through the refractory sealing member into the chamber.  The molten metal is supplied to the launder from the furnace at a rate faster than the rate at which the metal flows out of the cham-ber into the gating passages.  Thus, during the pouring opera-tion, a head metal is formed extending from the launder through the conduit and the seal and into the chamber, all of which may be filled with molten metal for a short period of time during the pouring process.  The molds are moved step-by-step succes-sively along a pouring rail, past a station where a nodularizing agent is placed into the chamber, if nodular iron is being pro-duced, and another station where molten metal is automatically poured into the chamber through the refractory seal member that is positioned in contact with the top of the mold when the mold is stopped at the pouring station and then after pouring is completed is removed from contact with the mold to permit the mold to be advanced and another mold positioned at the pouring station.

Abstract: OCEAN TIDE ENERGY CONVERTER                 ABSTRACT OF THE DISCLOSURE     A tide motor energy source includes a tidal piston with a valved chamber.  The piston drives a hydraulic ram to generate electrical power through a pressure accumulator and hydraulic motor.  The ram can be locked hydraulically to enable the tidal piston to be held fixed at a desired elevation and the valves in the chamber permit it to be filled with water or air.  The piston with its chamber filled with air at its low tide position and then released for controlled ascent while submerged acts as a submerged float for driving the ram upwardly while the tide runs in during one phase of its operation.  The piston with its chamber filled with water while locked at its highest position as the tide begins to run out, and then released to fall under control, acts as a weight suspended in air after the water level drops below the piston for driving the ram downwardly during the second phase of its operation.  The rising and falling motion of the tidal piston is used as the energy source.

Abstract: ABSTRACT OF THE DISCLOSURE The method and apparatus for testing the susceptibility of bacteria to antibiotics described in the U.S. Patent 3,832,532 and related patents are adapted for identifying various strains of bacteria by determining the light scatter indices (LSI) for a special group of antimicrobials, which have particularly significant characteristics with respect to identifying the strains of microorganisms, and analyzing them by a computer method, such as a quadratic discriminant function statistical technique, to identify the microorganisms to which the antimicrobials are applied.  It has been found that 14 antimicrobial agents provide an extremely reliable identification and it is believed that the identifying group of agents could be reduced without sacrificing too much reliability.  The agents preferably should be those which are not in common therapeutic use to avoid errors resulting from strains which have become immune to various therapeutically-utilized antibiotic agents.  A presently defined group of such agents includes approximately 36 members (later described herein of which number can be selected for reliable identification purposes by statistical techniques).
