Abstract: A co-pyrolysis process is disclosed for forming carbonized composite bodies in which co-pyrolysis of organic fibrous and matrix components is effected during initial pyrolysis. Improved interfacial bonding of composite bodies is achieved by combining fibrous precursors, or reinforcements with a controlled pre-shrink state, with an appropriate matrix to insure shrinkage matching during processing. Processing involves the heat treatment of an organic fibrous component, impregnation of the heat treated fibrous component with a resinous binder, forming a layup of the resin impregnated fibrous component, subjecting the layup to molding and curing cycles to form a laminate, pyrolysis of the laminate, and post-pyrolysis heat treatment of the pyrolized laminate.

Abstract: The present invention relates to a method and apparatus for inverting articles utilizing a fixture which comprises a pair of hinged plates each containing a plurality of holes. The holes in opposite sides are in alignment with one another and are connected to two vacuum switches so that vacuum to each plate can be independently controlled. Articles recognized as being upside down are placed over the holes in a first plate with the vacuum activated on that side to secure the articles to the plate. The plates are then rotated together about the hinge. The vacuum on the first plate is released, and the vacuum on the second plate is activated. As a consequence, the articles are transferred right side up to the second plate.

Abstract: Process and Apparatus for preparing O--X--O and O--X--X (i.e., zero nitrogen) suspension fertilizers wherein phosphate rock is acidulated with merchant-grade wet-process orthophosphoric acid. The instant invention requires only a minimal amount of relatively inexpensive equipment. The process comprises a first-charging step wherein a reactor vessel is partially filled with water of formulation, phosphoric acid, and phosphate rock. The resulting mixture is subjected to a digestion step for a predetermined period of time to effect reaction of the acid and phosphate rock added thereto. Said digestion step is subsequently followed by a second-charging step wherein predetermined amounts of potassium chloride and/or suspending agent are added to said reactor vessel.

Abstract: An air/fuel ratio detector comprising a pump and an electrochemical cell in which both the pump and electrochemical cell comprise an oxygen ion conductive solid electrolyte sandwiched between porous electrodes. One of the elements has an insulating substrate formed on a portion of the electrolyte. Over the substrate is formed a layer of semiconducting metal oxide. The cell and pump face each other with the cell providing an EMF and the pump being pumped by a pump current. The size of the resistance of the metal oxide layer indicates whether the air/fuel mixture is rich or lean relative to a stoichiometric mixture and the values of the EMF and pump current indicate the deviation from stoichiometry.

Abstract: A tunable bandpass filter comprising a pair of slot line resonant cavities formed in a metallic film covering the planar surface of a ferrite substrate. A magnetic biasing field of variable magnitude is generated and applied through the ferrite substrate transversely across the slot line resonant cavities. The magnetic field operates to change the electrical length of the resonant cavities due to the fact that the magnetic permeability of the ferrite material changes with the applied field.

Abstract: An electronic warfare software system design for an electronic counter measures system is presented which includes two general purpose processors (GPP) and multiple special purpose processors (SPP). The GPPs are the system controllers. These GPPs transmit setup data, including time information or hardware item and all related tasks for that function or hardware item. The SPPs are not required to handle multiple tasks and therefore do not require high complexity design. Also the complexity of the GPPs is reduced. The requirements of the system could be met by each SPP, keyed off a central clock strobe, with the resources of the processor dedicated to satisfying that function's time critical needs. In the two GPP setup the GPPs retain central control as well as completing overhead type tasks. There is one central executive control function that allocates tasks to be done to each of the processors.

Abstract: A contact structure and method of bonding III-V semiconductors which prevents shorting of the edges of the semiconductor chip and also allows the chip to be bonded with either major surface facing upward. Both surfaces include a gold pad surrounded by a material which is immiscible with the preform metal used to bond the chip to an outside surface. During fluxless bonding between the gold pad on one surface of the chip and the preform, the preform metal is prevented from wetting the edges of the chip. The opposite surface of the chip can be electrically contacted by wire bonding to the gold pad on that surface.

Abstract: An acoustic source is provided where a high pressure fluid is used to positively control the period an exhaust valve is open.

This results in conservation of air used to fire the acoustic source and also to achieve a desired signature.

Abstract: A low voltage trigger pulse is coupled to a three-stage driver which genees therefrom a high amplitude (e.g., 20 amp.) decaying current spike of predetermined width. The current pulse or spike from the driver is coupled to the gates of a multiplicity (i.e., 12) of parallel-connected field effect transistors (FETs) to turn or switch the same to the "ON" state. A laser diode array is series-connected with the parallel connected FETs so that when the latter is switched ON a very high (100 amp.) current pulse is delivered to the laser diode array to enable the same. At the cessation of the pulser current drive, a passive pull-down technique is used to enhance the turn-off of the parallel-connected FETs so that the laser diode array is quickly disabled. A protective overload circuit sets a limit to the average current through the laser diode array without affecting the pulse burst current.

Abstract: A press roll with adjustable flexion has a roll shell mounted to rotate around a fixed yoke and mounted with self-aligning bearings on a support cap in which the yoke is also supported on its own curved support. The press roll works in conjunction with a mating roll to form a press zone, near which there is a main hydraulic support that is positioned between the yoke and the shell and that transfers support forces from the yoke to the shell. The distance between the bearings of the shell is equal to that of the mating roll. The self-aligning bearing and the curved yoke support are mounted concentrically on a tubular collar of the support cap. There can also be supplemental supports outside the press zone for imposing additional flexion on the roll shell.

Abstract: A system for making a "jack-up" rig with its jacked-up legs and hull rigid and fixed together by the use of "rack chock" elements which are designed to absorb the maximum axial chord loading on the legs and transmit them directly into the hull. The "rack chock" elements are configured preferrably with a number of matching teeth for exact, in-line engagement with the legs' rack teeth, and are capable of being adjusted for vertical alignment and horizontal positioning to mate with the rack teeth position. By a series of screw jacks and/or secondary chocks, the "rack chock" elements provide rigid contact with both the legs and the hull structure and eliminate the requirement for the jack pinions to take the load (as is done in the prior art) in either jacked-up or ocean-tow dispositions.
