Abstract: A process for terminating the winding of one fiber layer being wound on a bbin in one direction and beginning the winding of another layer in the opposite direction wherein the bobbin is alternately rotated and traversed in small increments to obtain a transition from one layer to another which is free of gaps between adjacent turns in a layer and which does not slough off the bobbin.

Abstract: A method of obtaining data for mathematical characterization of a wave surface by transmitting a beam toward the surface so that the beam is reflected from an element of the surface in a direction determined by the instantaneous, two dimensional slope of the element. The reflected beam impinges on a screen as a spot whose time varying coordinates correspond to the time varying slope of the element. These coordinates are captured by scanning the screen with a raster scan which controls counters identifying the spot position. The instantaneous distance is measured by a capacitance probe to relate the captured coordinates to the corresponding angles of reflection by appropriate trigonometric relations.

Abstract: A stable boronated (.sup.10 B-labeled) compound, sodium mercaptoundecahydrododecaborate is infused in the form of the disulfide dimer, [.sup.10 B]Na.sub.4 B.sub.24 H.sub.22 S.sub.2, at a dose of about 200 .mu.g .sup.10 B per gm body weight. The infusion is performed into the blood or peritoneal cavity of the patient slowly over a period of many days, perhaps one week or more, at the rate of roughly 1 .mu.g .sup.10 B per gm body weight per hour. Use of this particular boronated dimer in the manner or similarly to the manner so described permits radiotherapeutically effective amounts of boron to accumulate in tumors to be treated by boron neutron capture radiation therapy and also permits sufficient retention of boron in tumor after the cessation of the slow infusion, so as to allow the blood concentration of .sup.10 B to drop or to be reduced artificially to a radiotherapeutically effective level, less than one-half of the concentration of .sup.10 B in the tumor.

Abstract: Hybrid-drive implosion systems (20,40) for ICF targets (10,22,42) are described which permit a significant increase in target gain at fixed total driver energy. The ICF target is compressed in two phases, an initial compression phase and a final peak power phase, with each phase driven by a separate, optimized driver. The targets comprise a hollow spherical ablator (12) surroundingly disposed around fusion fuel (14). The ablator is first compressed to higher density by a laser system (24), or by an ion beam system (44), that in each case is optimized for this initial phase of compression of the target. Then, following compression of the ablator, energy is directly delivered into the compressed ablator by an ion beam driver system (30,48) that is optimized for this second phase of operation of the target. The fusion fuel (14) is driven, at high gain, to conditions wherein fusion reactions occur.

Abstract: The tracking apparatus uses multi-processor modules for predicting in real time the parametric behaviour of radar signals to be jammed, as part of an electronic countermeasures system. The tracker system is partitioned into three board (module) types--(1) a subsystem request handler, which transfers data from system buses to the tracker system, (2) one or more multi-processor modules (each including a parameter memory and three arithmetic units with micro-sequencers) which does the actual track operation yielding the prediction data, and (3) a vector buffer module, which transfers the completed prediction data onto the buses for the receiver and transmitter. The system computer transfers to the tracker the necessary parameter information (latest time of arrival, threat type (stable, stagger, agile, etc.), angle of arrival, etc.) and initiates a track loop. Central to the operation of the trackers is the parameter memory which is divided conceptually into two main parts: pattern and parameters.

Abstract: Aqueous protein dispersions obtained from vegetable sources are subjected to successive pressure and cavitation cycling (e.g., centrifugal homogenization) at temperatures below the protein heat denaturization and under slightly alkaline pH's (e.g., pH 7.0-8.0) to provide a high NSI product. These high NSI products may be dried to provide a vegetable seed product having functional properties and utility similar to milk proteins. Buffered salt extracts from such spray-dried products reveal a predominant restructuring of the protein constituents into high molecular weight protein aggregates. Low NSI soy concentrates obtained by aqueous alcohol extraction processes are converted into a high NSI product possessing many of the desirable functional attributes of soy isolates plus those of milk proteins.
