Abstract: ABSTRACT OF THE DISCLOSURE            An air-to-air heat exchanger is provided for a gas turbofan engine to significantly reduce the quantity of cooling air that is presently needed to effectively cool the hot turbine parts.  Typically, the turbine is internally cooled with air bled from the compressor which, though cooler than the turbine, has been heated due to the work done on it by the compressor.  In accordance with the present invention, the heat exchanger is located internally of the bypass duct to place in heat exchange relationship a captured portion of the relatively cool bypass flow and this warmer compressor bleed air, thereby cooling the turbine coolant and significantly reducing the amount of such coolant required.          This results in a decrease in engine specific fuel consumption.

Abstract: Method And Apparatus For Generating And Utilizing A Compound Plasma Configuration Abstract A method and apparatus for generating and utilizing a com-pound plasma configuration is disclosed.  The plasma configuration includes a central toroidal plasma with electrical currents sur-rounded by a generally ellipsoidal mantle of ionized particles or electrically conducting matter.  The preferred methods of forming this compound plasma configuration include the steps of forming a helical ionized path in a gaseous medium and simultaneously dis-charging a high potential through the ionized path to produce a helical or heliform current which collapses on itself to produce a toroidal current, or generating a toroidal plasmoid, supplying magnetic energy to the plasmoid, and applying fluid pressure ex-ternal to the plasmoid.  The apparatus of the present invention in-cludes a pressure chamber wherein the compound plasma configura-tion can be isolated or compressed by fluid or other forms of mechanical or magnetic pressure.  A multiple chamber reactor de-vice is also disclosed, as are methods and apparatuses for using the compound plasma configuration in a number of diverse situa-tions.

Abstract: A B S T R A C T              A combination pressure regulating and flow control valve which includes a valve body and a cover means having an upstream port and a downstream port, and a fluid flow passage interconnecting said ports. An adjustable pressure regulator valve means is operatively moun-ted in said fluid flow passage. A check valve means is operatively mounted in parallel with said adjustable pressure regulator valve means, and it is operative to check the flow of fluid through said fluid flow passage when fluid is flowing through said fluid flow passage from the upstream port to the downstream port, and force it through the regulator valve means, and to allow flow of fluid through the check valve means when fluid is exhausted into said downstream port and out the upstream pressure port. A double acting, adjustable fluid flow control valve means is operatively mounted in said fluid flow passage which can provide either a meter in action or a meter out action in one direction with a free flow action in the other direction to the flow of fluid through said passage. The double acting, adjustable fluid flow control valve can also provide free flow action condition in both direc-tions without any metering action. An adjustable quick exhaust valve means 18 included for quickly exhausting the downstream pressure through a second parallel fluid flow passage simultaneously with the exhaust of fluid flow through the first named passage and check valve means. The adjust-able fluid flow control means includes a pair of needle valves that can be operatively mounted on a single valve stem, or on a pair of individual valve stems whereby both a meter in action and a meter out action can be provided without any free flow action.

Abstract: Case 790602 FAULT INDICATOR WITH EXTERNAL      EXCITATION MEANS           Edmund O. Schweitzer, Jr.     Abstract of the Disclosure A fault indicator for indicating the occurrence of a fault current in an electrical conductor indludes a reset circuit operable from an external electrical exci-tation source.  The external source is connected to the reset circuit by a cable formed from a flexible electrically insulating tubing segment within the lumen of which an electrically conductive coating is disposed.  The resulting high impedance electrical interconnection reduces the danger of electrical shock from inadvertant contact with the cable or the fault indicator circuitry, and precludes the source from being adversely affected should the cable become shorted to ground.

Granted: 1982-08-10
Abstract: ABSTRACT             Surface roughness is tested by an optical probing method which involves scanning a beam of light from a laser over a specimen workpiece via a semi-reflecting mirror and a cylindrical lens and detecting the specular component of the light reflected back through the lens and the semi-reflecting mirror to a photomultiplier the output from which is fed to an electronic processor circuit which derive a numerical valve representing the mean intensity of the reflected radiation.  A workpiece to be tested is then substituted for the specimen workpiece and a new numerical valve derived.  The two numerical values are compared, as by division or subtraction to obtain an out-put signal representing the relative surface roughness of the workpiece under test with respect to that of the specimen.

Abstract: FUEL INJECTOR FOR PRODUCING   SHAPED INJECTION PULSES     ABSTRACT          A fuel injector, especially adapted for diesel engines, produces a fuel injection pulse having a predetermined time-variable flow rate.  Preferably the injection pulse is ramp shaped which approximates a linear function of time.  A pressure chamber receives fuel at a substantially constant flow rate and an injection valve connected therewith opens in response to the pressure in the pressure chamber for delivering a fuel injection pulse to the combustion chamber. Means for absorbing a fluid pulse, in the form of an absorption chamber and flow restrictor, is connected with the pressure chamber to accept a ramp-shaped absorption pulse which is inversely related to the injection pulse.  The fuel flow rate into the pressure chamber varies directly with engine speed and the injection pulse has a slope and amplitude which vary directly with engine speed; the absorbing means is provided with time constant adjusting means responsive to speed of operation so that the slope and amplitude of the absorption pulse vary directly with engine speed.
