Abstract: An adaptive signal processing system for enhancing the signal-to-interfere characteristics on both receive and transmit using an in phase-quadrature correlator to control phase and amplitude adjust circuits located in the antenna signal paths. The amplitude adjustment provides amplitude balance control with variable delay lines between a quadrature hybrid and a sum-difference hybrid. The analog outputs of the correlator are digitized to control incrementally adjustable delay lines of the phase and amplitude circuits in binary steps.

Abstract: A fluidic oil viscometer for determining the degradation of machinery lubating oils compares the viscosity of the machinery oil with the viscosity of another fluid, such as air. Both the viscosity of the air and the viscosity of the oil are sensed, using capillary-orifice combination sensors, and the air viscosity reading is amplified using a series of laminar proportional amplifiers to equalize its change in viscosity with that of oil. The outputs of the capillary orifice combination sensors are applied to two different pressure gauges, the difference between these two pressure gauges represents the viscosity breakdown. This difference will be independent of temperature.

Abstract: A cryogenic cooler having multistage telescoping in-line regenerator-dispers in which the regenerator-displacer stages are progressively smaller from a pressure wave input end to the output cold end. Each stage from the input toward the output functions to produce a plurality of precooled expansion volumes for progressively lowering the temperatures at the input environment of each subsequent regenerator-displacer stage to maintain a temperature of about 8.degree. Kelvin at the output end of the cooler. Cooling concepts in which the multistage telescoping in-line regenerator-displacer may be used are the integral cycle, the split cycle, and dual fluidly control motion cycle.

Abstract: A system for the coupling of signals from a movable member, such as a tank upola, to a fixed member, such as a tank hull, includes a rotatable drum carrying an optic fiber slip ring (an optical wave guide which may be a rigid fiber optic bundle or a rigid plastic resin optic ring). Electronic-photo transducers, such as photodiodes or light emitting diodes, are embedded in the optic fiber slip ring and their light pulses are transmitted across a gap to an optic fiber block also containing electronic-photo transducers.

Abstract: A cartridge containing a propellant charge, and a separate projectile are dividually loaded into two independently operable sections of a gun breech assembly. The automatic loading operation is facilitated by separating the two sections during recoil movement, loading each component, and re-aligning both sections with the gun barrel in the battery position at the conclusion of counter-recoil movement.

Abstract: A Stirling Cooler with a three stage cold finger. The finger includes a sped displacer in a stepped cylinder. The cylinder is loosely surrounded by an outer shell, with regenerator material in the space between the outer shell and the cylinder. The displacer-cylinder define three swept expansion spaces each communicating with the regenerator space. Clearance seals exist between the displacer and the cylinder because of small diametrical clearance and long axial length with respect to the diametrical clearance.

Abstract: The invention is an improved apparatus for the removal of sodium carbonate from cyanide plating baths. The method involves the precipitation of sodium carbonate by the effect of cooling the cyanide plating bath liquid. A container is submerged in the solution with the container opening extending above the plating bath solution level. The container is filled with dry ice and water which produces a temperature of approximately zero degrees centigrade inside of the container. The solution adjacent to the exterior of the container is cooled so that excess sodium carbonate is precipitated as a crystalline deposit. After a desired interval, the container is removed with the encrustation of sodium carbonate for disposal.

Abstract: The laser light is polarized and sent through an electro-optic pockels cell here it is phased shifted in a duty cycle in accordance with the amplitude intensity. The light is then sent through an analyzer which will act as an attenuator to regulate the final amplitude output of the light.

Abstract: A fluid telemetry system is disclosed which utilizes an improved pulsing ice. The pulser comprises a bistable fluid amplifier. Both outlets of the bistable fluid amplifier communicate tangentially with a vortex chamber. A pulse in the fluid entering the amplifier may be produced each time the fluid flow is diverted from one outlet to the other.

Abstract: The highly sensitive spectrophone assembly of the subject invention simultaneously and continuously provides an accurate measure of the absorption of electromagnetic radiation by atmospheric gases and particulate matter by providing successive flow through chambers. The gases and particulate matter pass through the first chamber, are directed through a filter where the particulate matter is removed, leaving the gases to flow through the second chamber. The signal representative of the absorption of energy is generated in each chamber and fed into a differential amplifier, to provide an accurate indication of the particulate matter in the atmosphere being monitored. Grounding one side yields a signal attributable to the gaseous absorption.

The apparatus consists of two units: a main unit containing a laser and optics, and an external platform that rotates at an appropriate angular velocity, through a very small arc, during image recording of an object on the platform.

Abstract: In a missile system, a simple way to guide a missile in a predetermined tectory from launch to the impacting with a target for optimum warhead penetration of armor by a guided missile. Initially, the missile is guided in yaw by proportional navigation. Subsequently it is guided in pitch first by a pitch programmer until the missile reaches a predetermined gimbal angle between a line of sight of a seeker of the missile and a centerline of the missile, then in pitch by a pseudo-time-optimal closed loop controller to direct the missile pitch attitude at a predetermined rate toward a target until said missile reaches another predetermined gimbal angle, and finally by proportional navigation in pitch of the missile to the target.

Abstract: Reference scenes stored in a filter set containing an array of sets of suimposed, holographic, matched filters are optically correlated with input images displayed on an optically-addressed, liquid crystal, light modulator 34. In operation, a selected laser diode is energized to direct a polarized light beam through the collimating lens L1 to the reflecting surface of a polarizing beam splitter 35. After reflecting off the beamsplitter surface, the beam is expanded by positive lens L2 and passed to the liquid crystal modulator. There it is modulated by the input image and reflected; after which it is recollimated by positive lens L2, transmitted by the beamsplitter, and directed to a particular array location of the filter set dependent upon which particular laser diode is energized. The filter set is positioned to be in the back focal plane of lens L4 so that the Fourier-transform of the input image is incident on the particularly located, superimposed matched filter at 31.

Abstract: A recess or cavity is formed on the exterior of a fuze ogive. A piezo-eleic tape is positioned within the cavity or recess. Fluctuations in the pressure within the recess, caused by air flow over the exterior of the fuze, will cause the piezo-electric tape to produce an electrical signal or current.

Abstract: The reversible temperature coefficient of magnetization of a permanent magnet alloy over the temperature range from -50 degrees C. to +150 degrees C. is lowered by heat treating the alloy in a noble gas atmosphere or in a vacuum by the steps of(a) heating the alloy at about 1150 degrees C. for 1.5 hours (b) quenching the alloy in ice water, (c) heating the alloy at about 940 degrees C. for 2 hours, (d) lowering the temperature to about 700 degrees C. and heating for one hour, (e) lowering the temperature to about 600 degrees C. and heating for one hour, (f) lowering the temperature to about 500 degrees C. and heating for 2 hours, and (g) lowering the temperature to about 400 degrees C. and heating for 10 hours.

Abstract: A detector for detecting radiation from a Q-switched laser. The detector prises a plurality of silicon photo-diodes (10) which develop an output signal when struck by incident radiation from the Q-switched laser. The output of the photo-diodes is connected to a pulse-width discriminator (12) and a pulse-amplitude discriminator (13). The pulse-width discriminator generates an output signal only if the amplitude of the output pulse from the photo-diodes is less than 300 nanoseconds, signifying an input pulse from a Q-switched laser. The pulse-amplitude discriminator develops an output signal only when the photo-diode is saturated, again, indicating radiation from a Q-switched laser. The presence of a signal from either the pulse-width discriminator or the pulse-amplitude discriminator indicates that the incident radiation on the photo-diode was indeed from a Q-switched laser.

Abstract: A process and a microorganism for synthesizing cellulase enzymes are described. The microorganism is a mutant strain of an Ascomycete fungus capable of synthesizing cellulases. The synthesis of cellulases by the mutant is nonrepressed by glycerol, repressed by glucose but not subject to postrepression lag, and inducible to high levels by lactose. Furthermore, the combination of lactose with xylose elicits maximum cellulase synthesis by the mutant.
