Abstract: Splat Cooling of Liquid Metal Droplets Abstract An apparatus is set forth for the continuous produc-tion of highly cooled metal splats.  Melted metal is poured onto a spinning atomization disc means whereby liquid metal droplets leave the disc means in a horizontal plane.  An annular cooling gas jet flowing normal to the particle plane around the disc deflects the heavier liquid droplets to a conical splat plate which is fixed to rotate with said disc, where the droplets splat and cool, and are ejected by centrifugal force.  An annular space is located between said conical splat plate and said rotary atomization means for permitting the gas and other solidified particles to pass downwardly to a shield which directs the particles to a collection area.

Abstract: VELOCITY OPERATED STANDING VALVE            ABSTRACT OF THE INVENTION    A standing valve for controlling fluid flow through a well flow conductor.  The standing valve allows for formation fluids to enter the flow conductor downhole and to flow in one direction to the well surface.  The standing valve functions as a check valve to prevent fluids injected into the flow conductor at the well surface from flowing out the other end of the well flow conductor.  The standing valve is operated by changes in the velocity of fluids flowing through the valve.          When the pressure of fluid injected into the flow conductor from the well surface exceeds a preselected value, an alter-native flow path is opened within the standing valve to allow the injected fluid to flow in the other direction through the valve.

Abstract: Kobelt 26 us/w A CONTROL DEVICE FOR MARINE GEARBOX AND ENGINE             ABSTRACT OF THE INVENTION      A control function splitter for control-ling a clutch and gearbox assembly and a throttle, particularly in marine applications.  The splitter has main and override throttle shafts, and a clutch operating shaft connected to engine and assembly inputs.  The splitter has a cam which moves axially to reflect control head signals.  The cam has portions representing travel for gear engagement only with no throttle change, and travel between idle and full throttle  with no gear change.  A motion converting structure converts axial cam movement to limited clutch shaft rotation.  An interlock between the clutch shaft and override throttle shaft prevents rotation of the clutch operating shaft unless both throttle shafts are at idle, and also prevents rotation of the override throttle shaft unless the clutch shaft is in neutral.  The splitter reduces previous problems associated with non-lineality between a control head signal and the corresponding throttle output signal, and also improves positive "feel" of gear selection.   Also, tendency of engine speed governor to cause speed setting to creep is markedly reduced.
