Abstract: The invention is a device encompassing and warming the extremity of a wor in a cold wet environment. The device can take the form of a glove, sock and/or arm and/or leg warmer. The device contains a coil surrounding the extremity. The coil forms an envelope surrounding each extremity and each digit of an extremity. A water free, RF transmitting zone encompasses the coil envelope. The coil, extremity and RF transmitting zone combine to provide a resonant frequency with the operating frequency with which the coil is driven. The combination warms the interior of the extremity. The RF energy is provided from a source carried at some other point on the subjects body. The entire combination on each extremity and the power source can be encompassed in a shield layer which absorbs or reflects RF energy into the extremity.

Abstract: A synthetic peptide of the human malaria Plasmodium vivax, containing at st one repeat of a synthetic peptide having the amino acid sequence Ala-Gly-Asp-Arg (AGDR) which is a protective epitope found on the circumsporozoite (CS) protein of the sporozoites of the human maleria Plasmodium vivax. When a monoclonal antibody specific for this four amino acid sequence binds to the CS protein of the P. vivax sporozoite in vivo, infection is prevented. Also described are pharmaceutical formulations of these peptides.

Abstract: A novel immuno-dye reagent capable of detecting the presence of endotoxin in samples has been developed. The immuno-dye reagent comprises a solution of new methylene blue and an anti-endotoxin monoclonal antibody specific to a selected endotoxin. The immuno-dye reagent can be used in an assay to detect endotoxin by reacting the immuno-dye reagent with an endotoxin suspect pH adjusted sample, under hydrophobic conditions. The immuno-dye reagent can also be used in any application where binding of endotoxin is crucial, such as purifying endotoxin-contaminated solutions.

Abstract: A technique is presented involving a laser diode stablized in a single mode employing active cooling at a specific current density to produce a preselected wavelength of coherent radiation. This output is used to expose for a very short time, a very sensitive holographic recording material before the diode can return to an unstable multi-mode, hence multi-wavelength radiation condition which would have adverse consequences to the hologram-making process.

Abstract: A combination of optical interconnect technology with superconducting matal to form a superconducting neural network array. Superconducting material in a matrix has the superconducting current decreased in one filament of the matrix by interaction of the Cooper pairs with radiation controlled by a spatial light modulator. This decrease in current results in a switch of current, in a relative sense, to another filament in the matrix. This "switching" mechanism can be used in a digital or analog fashion in a superconducting computer application.

Abstract: A method of making a self-aligned FET includes the following steps. First, selectively doped heterostructure substrate having a predetermined crystalline structure is obtained having a heavily doped top GaAs layer, having a heavily doped AlGaAs layer under the top layer that is resistant to orientation-dependent etching, and having an undoped underlying AlGaAs layer and an undoped bottom GaAs layer. Then, an uppermost GaAs layer is deposited on the top layer. Then, an angular recess is etched through the uppermost GaAs layer and through the top heavily doped GaAs layer of the heterostructure substrate with an orientation-dependent etchant down to the etch resistant AlGaAs layer, whereby the length of the angular recess is wider at the base of the recess than at the top of the recess because of the predetermined crystalline structure and the orientation-dependent etchant. Next, a refractory metal gate of tantalum silicide is deposited in the recess.

Abstract: Diffraction limited, single narrow lobe radiation from a large area laser is achieved in a system using an external ring laser cavity to return radiation to the laser via a spatial filter and a Faraday rotator. An antireflectance coating of sufficiently small reflectivity added to the large area laser converts it into a laser amplifier which provides optical gain in a ring laser cavity.

Abstract: Superconducting compositions of the general formula A.sub.n Q.sub.m Cu.sub.3 O.sub.y are prepared by wet mixing a combination organic acid salts, inorganic acid salts and oxides of A, Q and Cu, wherein at least one salt is an organic acid salt, drying the mixed salts, and then heating the resultant mixed salts to a temperature between 500.degree. and 950.degree. C. The temperature is maintained for a time sufficient to form a substantially orthorhombic superconducting composition. The method achieves good results with only one heating step. The presence of at least one organic salt causes carbonate and nitrate salts of A, Q and Cu to convert to oxides at temperatures between 300.degree. and 400.degree. C. With lower processing temperatures, semiconductor materials and superconducting materials can be processed together.

The device comprises a channel of n-doped GaAs, a source and drain regions of n.sup.+ GaAs disposed at opposite ends of the channel, a semi-insulating GaAs layer disposed over the channel, with this GaAs layer having open first and second end surfaces disposed at an angle of greater than or equal to 45.degree. relative to the channel plane. A cavity is disposed in the GaAs layer exposing a portion of the channel, and a gate metallization is disposed over the GaAs layer and extending from the first end surface to the second end surface of the GaAs layer and directly contacting the exposed portion of the channel region in the cavity to form a Schottky barrier contact. This gate metallization is not disposed in contact with a significant portion of either of the first and second end surfaces.

Abstract: An improved laser-driven, two-way optic communication system for atmosphe use and enabling communication between remote stations. The system is generally made up of a transmitter-receiver (TR) arrangement at one station and a cooperative transmitter-receiver (CTR) arrangement at another station. The TR arrangement is generally made up of laser source beam means, polarizer means, polarized beam rotater means and appropriate lens means. The CTR arrangement is generally made up of appropriate lens means, beam splitter means and first and second phase conjugate mirror (PCM) means. The PCM means are mounted on piezoelectric means that are selectively dithered so as to enable control of the return signal. The TR means causes propagation of a rotated laser source beam polarization output via the atmosphere to the CTR arrangement during system use.

Abstract: A method for producing desired changes in a beam of coherent light radiating at .lambda..sub.1, comprising the steps of (a) splitting a beam of coherent light radiating at .lambda..sub.1, correcting one of the beams to achieve a desired wavefront and recombining this beam with the first, where a record medium (I) is placed such that the beams are separated by an angle determined by Bragg's law and the line spacing of the interference pattern formed by the two beams; (b) developing the first medium such that a diffraction grating of spacing d.sub.1 is recorded in a material, specifically sensitive to .lambda..sub.1, which will become the master; (c) illuminating the master with a second wavelength, .lambda..sub.2, selected by choice of a second medium which possesses very high diffraction efficiency. The second beam is split into two parts. The first is directed to the master. This diffracted order is recombined with the second beam.

Abstract: An apparatus and method for locating the vertical axis of symmetry of a sace of horizontal circular cross-section. The apparatus has a plumb structure that establishes a vertical line of sight, and a horizontal translating structure that preselectedly locates the plumb in the two horizontal dimensions. The plumb has at least three arms whose ends are constrained to lie on a circular perimeter which, because the arms are fixed to the plumb, is horizontally disposed. The translating structure and the arms are manipulated so that the end of the arms touch the surface, constraining the line of sight to be colinear with the axis of symmetry. A laser can make the axis visible. The apparatus and method are useable to locate the focal axis and focus of a parabolic antenna.
