Abstract: An eddy current flaw detector is held in a mounting block by a spring bias, the mounting block is selectively rotatable about a shank member for varying the radius of the detector as the shank rotates about a pivot point, turned by an electric drive mechanism.

Abstract: A backlash filter apparatus for the removal of spurious electrical components of a pre-established amplitude level from a voltage signal. The filter apparatus provide a backlash window to which the input signal comprising a desired signal and its spurious noise component is applied. The spurious noise component is removed in the backlash window, thus providing a jitter-free filter output.

Abstract: A moving target indicator apparatus utilizing charge injector device (CID) sensors to detect the presence or absence of a moving target. A signal from a possible target site in the sensor array is measured during a flow scan and is processed with the signal return from a second scan to determine absence or presence and direction.

Abstract: An anti-G valve and control system for providing a multivariable, multi-profile, pressurization of aircrew anti-G garments are disclosed. The ramp characteristic, the ramp onset level, a step onset, the step level, a limit pressure, are all controllable over the normal operating range. In addition, an optional ready pressure control is provided to just fill the anti-G suit volume and greatly decrease inflation time required to reach higher pressures.

Abstract: An assembly for baffling an associated optical system from off-axis radiation and, at the same time, reducing the thermal load by minimizing radiation absorption within the assembly. In its most basic embodiment, the assembly comprises: a rectangularly-shaped box-like housing having a specular internal surface; and, specular baffles that are sections of surfaces of hollow elliptic cylinders and that are positioned within the housing in spaced-apart relationship to each other and in a one-behind-the-other arrangement, and also are perpendicular to the sides of the housing.

Abstract: A miniature fuze for use with a bomblet munition having an arming and firing mechanism located adjacent one another within the fuze housing. The arming mechanism has no stored energy therein and relies upon a plurality of distinct operations to take place before cocking of the fuze begins. After cocking, the fuze is capable of being armed and can thereafter be detonated upon impact.

Abstract: An environment sensing system that prevents rotation of a grooved rotor surface mounted on a shaft, with a ball, until a deceleration force causes the ball to climb an inclined surface, a bias spring causes the detent grooves to maintain alignment with the ball.

Abstract: An attachment for use with an anti-G valve to substantially decrease the inflation time of an anti-G garment. A spring loaded, adjustable tension lever arm provides a downward force on a pressure valve causing the anti-G garment to partially inflate. The increasing garment pressure is applied to a diaphragm which causes the lever arm to rise and balance the force of the spring which is normally adjusted to maintain the pressurized suit at 0.2 psig "Ready Pressure". The garment remains partially inflated until the anti-G valve operating in the conventional manner causes the garment to inflate in response to external G-forces.

Abstract: A method for synthesizing perfluoroesters by effecting a reaction at subambient temperatures between a perfluorocarbon acid, or its derivatives, and a halogen fluorosulfate to produce an intermediate perfluoroacyl hypohalite which in turn is reacted with a suitable olefinic reactant to produce a perfluoroester.

Abstract: A seat mounted arm restraint net system for restraining a crewman's arms during an ejection sequence wherein a pair of nets, mounted with one on each side of the seat, are deployable by separate static lines passing through snubber boxes to frangible anchorages on the vehicle floor. Each static line is releasably attached to a separate swinging arm rotatably secured to its seat side such that the swinging arms throw the free net sides laterally outwards and then release the nets to close over the crewman's arms.

Abstract: Diphospha-s-triazines wherein the two phosphorus atoms are substituted by aromatic groups and the carbon atom is substituted by either a perfluoroalkyl or a perfluoroalkylether moiety. The triazines exhibit a broad range of properties and are useful as antioxidant-anticorrosion agents, lubricants, and hydraulic fluids.

Abstract: An alloy for brazing a silicon die to a gold-plate kovar header consists essentially of 19 to 21 weight percent tin and 0.6 to 0.8 weight percent silicon with the balance being gold. The alloy melts at a temperature below 200.degree. C. which is substantially lower than that of the conventional gold-silicon eutectic alloy.

Abstract: A method for inhibiting the effects of fretting fatique in a pair of opposed titanium alloy mated surfaces through the use of a copper shim insert positioned between and in contact with the mated surfaces.

Abstract: 1.

Abstract: A high radiation level dosimeter capable of measuring total ionizing radiation doses from gamma ray, X-ray, or E-beam sources by detecting charge variations in the gate structure of a metal nitride oxide semiconductor (MNOS) type transistor. The MNOS device displays a unique combination of characteristics allowing the storage, removal and measurement of the electrical charge trapped within its gate structure. The magnitude of the charge remaining is ascertained by measuring the threshold voltage necessary to produce a prescribed output current response, while the rate at which this charge decays is dependent on both the elapsed time and total ionizing radiation dose.

Abstract: A wing pivot assembly for variable sweep wing aircraft for movably securing a wing of the aircraft to the fuselage. The wing pivot assembly has a pivot pin supported by a pair of inboard lugs secured to the fuselage of the aircraft. The wing is, in turn, movably secured to the pivot pin by bearings interposed between the pivot pin and a pair of outboard lugs. In addition an outboard shear fitting located between the wing and the pivot pin movably supports the wing and transfers shear loads to the pivot pin. An inboard shear fitting and anti-rotation device secures and transfers shear loads between the pivot pin and the fuselage. As a result of the above arrangement a multi-load path structure provides for a fail-safe pivot assembly.

Abstract: A doubly adapative constant false alarm rate (CFAR) apparatus utilizing a doubly adaptive detector which is based upon the use of an auxiliary parallel adaptive detector in addition to the conventional main adaptive detector. The auxiliary adaptive detector has a lower threshold setting. The threshold crossing rate of the auxiliary detector, which depends upon the clutter statistics, is used to adjust the base multiplier setting of the main detector.

Abstract: A system for generating fluorine for use as a gaseous reactant in a chemical laser from a storable gas supply of NF.sub.3.

Abstract: The intrusion detection capability of a guided wave radar intrusion detection system is selectively disabled in certain areas, such as gates or portals to permit ingress and egress of personnel and vehicles without affecting overall system performance and without requiring an independent detection system. This is realized by means of an integral system portal enable-disable device. Guided wave radar intrusion detection systems employ two parallel leaky transmission lines, one transmitting and the other receiving radar signals. Violation of the area between the leaky transmission lines by an intruder results in a signal that indicates the occurrence and its location. Gate areas are remotely enabled or disabled by a switching circuit that switches a segment of non-radiating transmission line into or out of the transmitting leaky transmission line in each selected gate region.
