Abstract: A hydrofoil sailboat with a slender hull and a foil-shaped sail spaced laally therefrom. The hull has one flat side facing the sail and one convex side. The sail is inclined from the vertical toward the hull and is supported at its base ends by a pair of freely swiveling waterskis. The hull supports a rudder at each of its ends, the rudders being hydrofoils with their flat sides facing the sail. The length-to-width ratio of the hull is no less than 5:1 and the inclination of the sail about 30.degree. from the vertical.

Abstract: Synchronous plating techniques for reducing adjacent bit disturb charactetics or interactions in a magnetic memory wire include the step of sinusoidally and smoothly depositing the magnetic layer on the outside surface of the wire so as to increase the effective magnetic path length between adjacent bits. The resultant wire has changing cross-sectional dimensions corresponding to the varying sinusoidal configuration of the wire.This invention concerns a film-plated memory wire of improved characteristics and the method of making the same. The term "memory wire" is used to designate a magnetic recording and reproducing element for recording or reproducing magnetic signals by magnetic flat interlinkage with a magnetic transducer head during relative motion of the wire and head.

Abstract: A quick release latch has a pair of jaws pivotally mounted for holding a d. An abutting toggle link mechanism having a master and a slave link controls movement of the jaws. The master link is pivotally connected to one of the jaws, and the slave link is pivotally connected at one of its ends to one of the jaws, and at its other end to the master link. The master link has a stop pin thereon which contacts the slave link when the linkage mechanism is moved forward past a center line position, permanently restraining the jaws in their closed position. Cantilever springs help to hold the jaws in their closed position. Pulling the toggle links aft thru the center line allows the force of the load and cantilever springs to rapidly open the jaws.

Abstract: Two wing semi-spans of unitary construction are mounted on an aircraft fuage. Screwjacks mounted in the fuselage extend and retract each semi-span while maintaining the wing sweep angles constant. Pivoting struts and carriage blocks are employed to support the extensible semi-spans. Rollers connected to the carriage blocks are constrained to follow tracks mounted in the fuselage, providing support at the inboard end of each semi-span.

Abstract: A solid state electronic circuit designed to accept coded information to trol the function of a mine mechanism.

Abstract: Apparatus for multiplexing a large number of digital signals onto a few aog channels using a level code encoded multiplexer. Each digital signal to be multiplexed is assigned a unique reference level to represent a logical "one", with all digital inputs assigned the same zero ground as a base line for a logical "zero".

Abstract: The present invention relates to improved method and structure for producing an electric discharge in a laser cavity which eliminates arcing and permits electron energy to be chosen based on energy requirements for accelerating the electrons rather than energy and/or pressure requirements for supplying electrons. An auxiliary discharge is maintained to provide the electrons necessary for laser excitation. A transverse electric field is then superimposed to impart the energy required to accelerate the electrons.

Abstract: A temperature-sensitive disarming element for a warhead comprising a retang ring for the detonation-lead positioning cup. The retaining ring is made from a material whose characteristic is that its mechanical strength degrades rapidly at a temperature of about 250.degree.-300.degree.F. so that it permits the positioning cup to be blown off in a flame environment. This prevents pressure buildup in the warhead charge, which would lead to detonation of the warhead.

Abstract: The temperature of heated gaseous plasmas in non-controllable, non-laboratory applications is measured by an improved spectroscopic analysis. A low atomic number trace gas, such as hydrogen, or helium, is added to the plasma. Temperature is obtained by measuring the ratio of the intensities of two lines of the hydrogen-atom series, e.g. H.sub..alpha. and H.sub..beta. lines of the BALMER SERIES. The technique is applicable in the few electron volt range and the method is applicable even though the plasma is not optically thin and the total number density of the particles in the plasma, at the instant the measurement of temperature is performed, is unknown.

Abstract: An improved antenna system having a plurality of loop antennas surrounded coaxial shields which have dual electrostatic shield gaps therein. A shunt capacitance is placed across each of the shield gaps. The shunt capacitances are matched and variable among discrete values. Variation of the capacitances provides increased antenna sensitivity without a change in physical dimensions of the antenna.

Abstract: An explosive linear cutter for cutting materials comprising an explosive rge sheathed in a metal covering, a support for said charge surrounding the covering except for a slot facing the target material to be cut. Separation of the target material is effected by propelling a fragment of metal sheath at high velocity through the slot and into the target upon detonation of said explosive charge to thereby achieve a clean highly directional cut along a desired separation line.This abstract is for the purpose of providing a non-legal brief statement to serve as a searching tool and is not intended to limit the scope of the invention as disclosed herein nor limit the scope or fair meaning of the appended claims.

Abstract: A combination of a wobble-scan infrared (IR) seeker with an unscanned pul laser (L) seeker. Target IR&L energy is passed through a focusing lens system to a wedge filter which is mounted on a rotating gyro-stabilized platform. The filter separates the IR&L signals by reflecting the L signal from its top surface and the IR signal from its bottom, slanted surface. The L signal is focused on a quad cell detector and detected. The IR signal passes through this detector and is sent through a reticle which pulse-codes it. The pulse-coded IR energy is then focused by another lens on an IR detector.

Abstract: Positron-emitting probes that have certain features that facilitate the use f positrons for nondestructive testing of fatigued metals. The features include the use of an unfatigued substrate for supporting the positron-emitting material, electric and/or magnetic fields to concentrate the positrons on the test item, and a thin scintillator window for use with those radioactive materials that emit a positron without emitting a time-correlated gamma photon.It should be understood that the foregoing abstract of the disclosure is for the purpose of providing a non-legal brief statement to serve as a searching-scanning tool for scientists, engineers and researchers and is not intended to limit the scope of the invention as disclosed herein nor is it intended that it should be used in interpreting or in any way limiting the scope of fair meaning of the appended claims.

Abstract: A lateral photodetector of improved sensitivity and method of making the e. The photodetector consists of semiconductive wafer, having a transparent layer of metal deposited on its front face to form a Schottky barrier. A negative bias is applied to the Schottky barrier to form a depletion region in the wafer. A low resistivity layer is formed on back of the wafer to which four signal electrodes are attached. Before forming the cell, the semiconductor wafer was exposed to nuclear radiation to increase the responsivity of the cell.

Abstract: A transducer, and method for making it, comprising a composite film for sing pressure comprising a pair of film sandwiches, each sandwich comprising a poled polymeric films with metallic film electrodes on opposite surfaces. One electrode does not extend quite to the end of the polymer and is considered the "hot" electrode. Two such transducer film sandwiches are cemented together with the hot electrodes in contact with each other, the center wire from a coaxial cable being in contact with and between them. The outer electrodes are electrically connected to the shield of the cable and the connection is encapsulated.

Abstract: A communications or radar radio receiver, of modified superheterodyne design, that will accept and process unknown radio frequency (R.F.) signals without the necessity of concurrent tuning of the R.F. stage(s) and adjustment of the local oscillator to a frequency proportional to the carrier frequency. The radio receiver employs a rotatable directional receiving antenna having adequate directivity indices to isolate and discriminate between adjacent signals in angular coordinates. When used in radar receiver applications in combination with an off-set frequency transponder, range and bearing can be obtained without resorting to a common specific frequency requirement for both radar and transponder. In such a case the servo of the radar receiver is used to position the antenna for detection of the carrier signal thereby providing an azimuth indication of the position of the unknown transmitter.

Abstract: The semiconductor target of a GEISHA or EBIC device is integrated with an jection laser diode to form a unitary structure. The electrons created in the GEISHA by impact ionization are swept directly into the injection laser to cause lasing action. This eliminates the need for transmission line connecting the GEISHA to the injection laser diode.

Abstract: An oil-in-water monitor for monitoring the effluent of an oil-water separator. A pressure vessel coalesces oil from the effluent and gathers the oil in a collection section which is automatically emptied after an hour. If more than a predetermined amount of oil is gathered in the hour, an oil-sensing probe sends a signal to activate a warning light valve which permit pipes to return the effluent to the separator.If the effluent becomes too turbid, a turbidity senser activates an alarm and the valves which permit pipes to return the effluent to the separator.If the coalescer unit clogs, an indication is given by a differential pressure gauge.

Abstract: An isolator for enclosing a flexible waveguide at an antinode point along s length to attenuate movement of the waveguide and prevent its reaching a resonant condition, the isolator comprising a thick band of metallic wool impregnated with a low-density rubber foam contained within an elastomer jacket and supported by a snugly fitting bracket around its outer circumference which is firmly attached to a relatively immobile foundation.It should be understood that the foregoing abstract of the disclosure is for the purpose of providing a non-legal brief statement to serve as a searching-scanning tool for scientists, engineers and researchers and is not intended to limit the scope of the invention as disclosed herein nor is it intended that it should be used in interpreting or in any way limiting the scope of fair meaning of the appended claims.
