Two approaches are proposed to attack the problems of fixturing process. First, a novel hardware holding system, Dexterous Vise, is proposed. Functionally, a single Dexterous Vise is capable of revealing four faces of the clamped workpiece to the cutting tool without re-fixturing, which actually increases one degree of freedom to the machine tool. A pair of Dexterous Vises, the "Dual-Vise", ena ...

Herein, an innovative aircraft weighing system based on a set of piezopolymar film pad sensors is described. The wieghing system, which would operate automatically as the aircraft taxi over it, would be unobtrusive, accurate, and reliable. These sensor pads could be integrated into the flight deck surface below the grated rubber surface finish. These thin (20-30 mils) piezopolymer sensing pads ...

Herein, ACX proposes to develop compact, low cost, integrated smart packs for vibration reduction. Each package would include actuators and sensors, drive and signal conditioning electronics as well as simple controllers to yield a self standing solution to vibration problems. The electronics module would be low cost and compact. The pack would run off of standard available power supplies and w ...

N/A

SEVERAL TECHNIQUES WHICH HAVE BEEN USED BY ACL TO MEASURE RESPONSE OF BOTH FILAMENT-WOUND AND BRAIDED GLASS, KEVLAR AND GRAPHITE EPOXY COMPOSITE TUBES WILL BE EMPLOYED IN THE INSTRUMENTATION OF A VARIETY OF FILAMENT-WOUND COMPOSITE STRUCTURES. THESE STRUCTURES WILL BE CHOSEN BY ACL AFTER TECHNICAL DISCUSSIONS WITH MICOM PERSONNEL, AND MAY INCLUDE GOVERNMENT FURNISHED STRUCTURES OF PARTICULAR INTER ...

The proposed effort in Phase I is to identify properties of propellants that solidify at cryogenic temperatures, "cryosolids", that will be tested in Phase Ii and to deliver a detailed design of a cryogenic testing device. This device will be able to measure tensile, flexural, shear and compressive strength, elastic moduli, and hardness of these cryosolids. In addition, this device will be able ...

A MACHINE TO EVALUATE THE FRICTION AND WEAR PROPERTIES OF MATERIALS AT TEMPERATURES UP TO 1000 DEG C IS PROPOSED. BOTH LUBRICATED AND UNLUBRICATED TESTING WITH LIQUIDS AND SOLIDS WILL BE POSSIBLE USING A PIN-ON-DISC GEOMETRY. COMPLETE CONTROL OVER THE TEST ATMOSPHERE AND MANUAL OR COMPUTER-CONTROL OF ALL VARIABLES WILL BE POSSIBLE DATA ACQUISITION AND STORAGE WILL BE PERFORMED BY COMPUTER. THE TRI ...

THE OBJECTIVE OF THE PROPOSED PROJECT IS TO EVALUATE THE FEASIBILITY OF AN ON-LINE MONITOR OF OIL CONDITION WHICH WOULD DETECT THE PRESENCE AND NATURE OF DEBRIS PARTICLES IN LUBRICATING OIL SYSTEMS. THIS WOULD PROVIDE A MORE TIMELY AND LESS LABOR INTENSIVE METHOD OF OIL CONDITION MONITORING THAN PRESENT METHODS THAT INVOLVE OFF-LINE ANALYSIS. THE PROPOSED APPROACH WOULD CONSIST OF MEASURING THE FO ...

THE AES CORPORATION HAS DEVELOPED A NOISE PROCESSOR (NP). THE PROCESSOR HAD THE ABILITY TO DETECT A SIGNAL OF KNOWN PULSE WIDTH BURIED DEEP WITHIN THE R.F. NOISE FLOOR OR ELECTRONIC JAMMING. THE COMBINATION OF PROPRIETARY HARDWARE AND SOFTWARE ALLOWS THE NP TO SEARCH FOR A VERY EXACT SIGNAL. THE SIGNAL PARAMETERS ARE PROGRAMMED INTO THE SOFTWARE. THE TWO CONCURRENT PROCESSORS ARRIVE AT THE PROBABI ...
