Abstract: ABSTRACT            An undersea weapon comprising a warhead, a rocket motor, detection, homing and control systems and a hydropulse underwater propulsion system in an integral unit.  The weapon is launched at a previously detected target, such as a submarine, on a ballistic trajectory through the air by means of the rocket motor.  The weapon enters the water near the submarine, which is thereafter detected by an on-board system incorporating both active and/or passive de-tection.  The thus-determined submarine direction is uti-lized by the control system to guide the weapon toward the submarine under water.  A hydropulse motor utilizes the empty rocket motor as the propulsion chamber and pro-vides the under water propulsion to propel the weapon through the water toward the submarine, where the warhead then detonates on contact with the submarine.  Alterna-tively, the weapon may be air dropped near a previously detected target, in which case there need be no propellant in the rocket motor.  The hydropulse motor operates by re-peatedly filling the chamber with water and expelling the water at high velocity through a converging nozzle in succeeding pulse stages.  During the intervals between pulses, the detection system monitors the submarine free of noise from the on-board propulsion motor.

Abstract: IMPROVED PROCESS FOR PRODUCING CARBOXYLIC ACID SALTS          ABSTRACT        An improved process for reacting an alcohol with a caustic at a reaction temperature in the presence of a catalytic amount of metallic zinc or a zinc compound to produce a final reaction mixture containing carboxylic acid salts and to liberate hydrogen.  The improvement comprises mixing (i) the caustic; (ii) the catalytic amount of metallic zinc or zinc compound, and (iii) an effective amount of an inert diluent for the final reaction mixture, to form an intermediate reaction mixture.  The effective amount of diluent is an amount sufficient to maintain fluidity of the final reaction mixture.  A preferred diluent is mineral oil.  The intermediate reaction mixture is then heated to the reaction temperature.  Alcohol is then added to the intermediate reaction mixture over a period of time to form the final reaction mixture.  The improved process permits greater control of the process thus reducing the tendency of the reaction mixtures to foam and solidify.

Abstract: ABSTRACT OF THE DISCLOSURE A device to control the flow of fluid uses a cam and ratchet wheel.  A valve is operated by the cam portion of the wheel, which bears against the valve stem causing it to open.          Fluid flow causes a pawl to drive the ratchet portion of the wheel, rotating the wheel until the valve stem bears against a low point in the cam, permitting the valve to close.  A part of the ratchet portion does not contain ratchet teeth, in which area the pawl cannot drive the wheel.  In this area, the cam has an increasing radius from a radius corresponding to a closed valve, to a radius corresponding to a fully open valve.  This permits manual control of fluid flow without disengagement of the device.

Abstract: A TWO TERMINAL HALL-SENSOR               Abstract of the Disclosure An integrated circuit includes a Hall-element, a voltage regulator, and a threshold detector.  DC power is supplied through a pair of terminals that may be con-nected to a remote DC voltage source.  A switchable con-stant current sink circuit connected across these termi-nals is turned on and off in response to the two output states of the threshold detector that in turn is respon-sive to the Hall-element output voltage.  Thus the DC current flowing in the two DC supply lines is a predict able large value or small value corresponding to a low and a high magnitude magnetic field at the sensor, even when the supply DC voltage changes over a wide range.

Abstract: ABSTRACT OF THE DISCLOSURE        A method is disclosed for making ductile iron castings having thin walls.  Molten grey iron (preferably 3.5-4.2%C, 1.5-2.4% Si, and no greater than .65% carbide formers) is introduced to a mold assembly and nodularized/ inoculated in such assembly prior to passing into the mold cavity of the assembly.  The treated molten iron is fed into the mold cavity and into one extremity of a thin space thereof (.2 inches thick or less and a length of at least 12 times the thickness).  The treated molten metal is additionally mixed by vortical or turbulent flow immedi-ately downstream of the treatment chamber as it is being conveyed to the mold cavity.  While continuing to feed the treated molten iron to fill the mold cavity, a reservoir of the treated molten iron is created at a midstation of the thin space.  The reservoir acts to conserve the heat of the molten metal and thus feed hotter molten metal to the remainder of the thin space and other connected cavity portions.  The reservoir space also serves to define an integral functional part of the casting when solidified.

Granted: 1983-12-27
Abstract: Abstract of the Disclosure An electronic cylinder identification system is dis-closed for identifying the occurrence of a predetermined cycle position for a reference cylinder and synchronizing fuel injection for a multi-cylinder engine in accordance thereto.  A four cylinder engine rotates a rotary body having two 90 degree spaced peripheral projections and two stationary reluctance sensors are positioned 180 degrees apart about the body and sense the passage of the rotary body projections.  Logic circuitry receives sig-nals from the two sensors and determines which sensor is currently providing a logic pulse indicating the passage of a projection and which sensor previously provided such a pulse.  The logic circuitry utilizes this information to identify the rotational position of the rotary body by differentiating between occurring identical sensor pulses based upon which sensor previously produced a pulse. Preferably the rotary body is rotated by the engine cam-shaft which is rotated at one half of the speed of the engine crankshaft which drives the pistons in the engine cylinders through their full engine cycle in two crank-shaft revolutions.  Fuel injection apparatus is operated in accordance with the identified rotational position of the camshaft.

Abstract: SELECTIVELY ETCHED BODIES            Abstract of the Disclosure Bodies having conical structures with dimensions on the order of the wavelength of visible light are prepared by a specific process.  This process involves the formation of a mask by depositing a material that forms the mask onto the body to be etched and choosing the mask material so that it does not substantially wet the surface of the body.  The mask thus fabricated has hill-type formations where the spacings between these formations are of the order of the wavelength of visible light.  An etchant that etches the mask at a specific rate relative to the underlying body is then used to perform the etching procedure. Exemplary bodies produced by the procedure include tungsten textured bodies that exhibit light emissivities significantly higher than those possessed by the corresponding untreated tungsten material.

Abstract: Abstract of the Disclosure Beverages are dispensed from time to time from low cost bulk plastic or equivalent thin film bags rolled up inside a dispenser comprising a coiling spiral formed from a strip sheet constant force spring to squeeze out its contents completely and to produce dispensing force at all times.  The coil spring strip may be of plastic, metal, elastomer or fibrous materials and may form a wall of the bag so that the container may be made at very low cost for storage of bulk fluids including carbonated beverages for dispensing therefrom one serving at a time. The dispensing method thus provides for maintaining pressure upon stored fluids continuously during dispensing and storage in bulk for dispensing multiple servings from time to time and automatic dispensing without manual pressure upon the container.  Accordingly, carbonization is maintained in carbonated beverages by means of spring force pressurization sufficient to prevent effervescence, at normal serving temperatures.  Dispensing occurs automatically without entry of air or contamination so that sterile milk or the like may be intermittently dispensed during non-refrigerated storage.
