Abstract: Helicopters employed in emergency situations have been adapted for a vari of external uses. For example, step and cargo carriers have been attached to the skid supports of these helicopters. Gun mounts and camera mounts have been used. In order to provide for such external rigging, helicopters have been permanently altered. To avoid such permanent alterations straps or belts have been used to hold external equipment. However, the utility of such straps is extremely limited. It creates a stabilization problem. The invention herein provides an external cargo carrier capable of accepting a wide variety of external devices for use in emergency situations without permanently altering the helicopter. A totally self-contained framework is provided which includes stabilization means.

Abstract: In the transportation by helicopter of specialized cargo externally, such stokes litters, personnel carriers, auxilliary fuel tanks, gun mounts, and the like, it is frequently necessary to switch the carrying apparatus from one type of load to another. Normally, in order to provide for such external cargo a helicopter must be permanently altered to avoid the use of unreliable belts and straps. Permanent helicopter modifications are not totally acceptable in emergency situations. A helicopter cargo carrying apparatus is provided herein which is not subject to these objections. A pallet-like frame, upon which the load is secured, or which forms the base of the load carrying apparatus such as a platform or litter is provided.

Abstract: A socket wrench modified by the addition of auxiliary gripper ribs to either prevent bolt head stripper action or to minimize the adverse effects of such stripper action. In one case the bolt head is initially formed to have grooves in its side surfaces mated to gripper ribs on the wrench. In an alternate arrangement the gripper ribs are designed as cutter devices to form grooves in the bolt side surfaces by the application of a hammering force on the wrench.

Abstract: A distortion identification method which produces an undistorted rectilin cross grid pattern for comparison with any distortion and curvature of field in a display system. An undistorted rectilinear grid, representing an infocus view of the display where an observer's eye would normally be in a display system, is positioned to be optically projected by a collimating lens and the optical element back to the display focal surface. A curved cross grid pattern of the rectilinear grid is laid on a glass substrate, which is form fitted to the display focal surface, by projection photolithography. The curved cross grid pattern indicates the shape of the focal surface required to present a high resolution display emanating therefrom which is in-focus to an observer viewing the display.

Abstract: More than ten different wavelength channels are multiplexed over a single tical fiber for use in optical slip ring assemblies. The ends of multimode fibers, through which light signals of different wavelengths are transmitted, are packaged and fused to the end of a large core fiber. The single large core fiber in which the combined signals are transmitted can be used in an optical slip ring assembly in the same way as a single fiber containing one wavelength. The alignment accuracy is greatly enhanced for the large core fiber.

The device of the present invention is disposed for removal of the connectors from the printed circuit board without causing damage to the board.

Abstract: A spring loaded lever is tied down by a resistor and released when an over supply of voltage is applied to the resistor from a command source. The lever can have a string attached to it such that it will open a container when the resistor breaks. Or the lever can have a weight on it which will break a rod which is being used to tie down a load. A rod can be a fuse such that when the fuse is broken an electrical signal can be generated to give an indication of the release.

Abstract: A direct low temperature process for the preparation of pure magnesium borohydride diammoniate or the deuterated analog thereof based on the addition of 90-95% of the stoichiometric amount of NH.sub.3 to an excess of Mg(BH.sub.4).sub.2.X(C.sub.2 H.sub.5).sub.2 O in a benzene reaction solvent in accordance with equation 1: ##STR1## wherein X is a numeral from about 2.0 to about 2.5; or when the reaction is conducted in an ether reaction solvent with the same quantities of reactants and under the same experimental conditions, the triammoniate or the deuterated analog thereof is formed in accordance with equation 2: ##STR2## wherein X is a numeral from about 2.0 to about 2.5. In either case the pure product is readily isolated by filtration, solvent washing to remove excess Mg(BH.sub.4).sub.2.X(C.sub.2 H.sub.5).sub.2 O, and vacuum drying at ambient temperature. Yields are 95-99%; purities are typically about 97%.

Abstract: A connector as disclosed for connecting fluid passages through a flexible eet material. The connector is appropriate for use in connecting the coolant lines of a personal cooling garment through a waterproof immersion suit or a chemical proof outer garment. The connector includes inside and outside connector blocks with matching faces that sandwich the sheet material between them. Fluid passages through the two blocks meet at respective ports in the matching faces and are joined by coupling sleeves extending through holes in the sheet material. O-rings around the ports seal the holes through the sheet material. A cap screw or the like secures the two blocks to one another. The connector is equipped with valve male fittings and male lock components of a standard connector system that is now used for personal cooling garments. This allows the use of the connector in conjunction with an existing and satisfactory "zero leak" connect and disconnect system.

Abstract: A hoist that includes a winding drum for a load-lift cable mechanism. The um has two drum sections of slightly different diameter; end portions of the cable are wound in different directions on the drum sections, so that one cable section winds onto a drum section while the other cable section winds off the other drum section. The effect is to provide a very slow net cable motion related to the difference in drum section diameters. The hoist includes a latch mechanism adapted to suspend the load from the boom during certain periods of a load transfer operation.

Abstract: A pneumatically-operated unlocking system suitable for use on the door of a igh security building such as a military weapons storage structure, in which each one of a pair of unlocking keys is provided with a different combination of holes and no holes arranged in an n-position pattern to define an n-bit binary code. An encoder outside of the building pneumatically reads the said binary codes on the two unlocking keys in sequence and transmits the resulting pneumatic binary codes through conduits in the building walls to a logic device inside thereof where the binary codes are compared to two n-bit reference pneumatic binary codes derived from a pair of reference keys located inside of said building. If the codes on the two unlocking keys match those on the reference keys, a pneumatic output is produced which can be used to unbolt the door from the building.

Abstract: The incorporation of a nitrated pentaerythritol additive selected from the ono-, di-, tri-, and tetra-nitrated pentaerythritols into hydrazine is effective in lowering the freezing point of the combination while enhancing the performance of the monopropellant by contributing to the total energy of the monopropellant combination. Hydrazine content varies from about 65 to 95 weight percent while the additive of a nitrated pentaerythritol varies from about 5 to about 25 weight percent. An optional additional additive of methyl alcohol from about 5 to about 20 weight percent can be employed with a corresponding adjustment in weight percent of hydrazine when said additive of methyl alcohol is employed in addition to said additive of said nitrated pentaerythritol.

Abstract: The laser source energy and the target source energy goes through a common ptical path to a beam splitter. The energy from the target source is filtered, allowing only the laser information to pass through to the laser quadrant detector. The second path from the beam splitter has a blocking filter to block the laser energy, and the remaining energy, that of the target source, is measured by the target quadrant detector. The geometric translator is a computer controlled azimuth and elevation gymbal device which tracks (drivers to null) the target source. The target source is a strobe lamp. The angular information from the dual quadrant detectors and the geometic translator are fed into an compact mini-computer.
