Abstract: An  improved  process  for  producing  an  anisotropic  pitch product  suitable  for  carbon  fiber  manufacture.   A  carbonaceous feedstock substantially free of mesophase pitch is heated at elevated temperature while passing an oxidatively reactive sparging gas such as air through the feedstock. The oxidatively treated feedstock, which remains substantially free of mesophase pitch,  is then heated at a higher temperature in the presence of a non-oxidative sparging gas to produce  an  anisotropic  pitch  having  from  50  to  100% by  volume mesophase which is suitable for producing good quality carbon fibers.

Abstract: The use of certain prepolymers of 4,4'-methyienebis-(phenyl isocyanate), in place of the latter diisocyanate itself in the preparation of polyurethane-polyureas using aromatic diamine extenders, has a number of advantages par- ticuiariy when the compositions are prepared by reaction injection molding techniques using two streams of reactants. The principal advantages are (i) a useful increase in gel time and (ii) a ratio of amounts of the two reactant streams which more nearly approaches 1:1.This latter factor not only improves the efficiency of mixing of the components in the mixing head but, together with the longer gel time, significantly increases the output of mixed reactants per unit of time. The prepolymers of 4,4'- methyienebis(phenyi isocyanate) employed to achieve the above results are those derived from polyoxy-ethylene polyoxypropylene polyether diols and triols (MW = 1000-10.000), polytetramethylene glycols (MW = 600-5.000) and polyester diols and triols (MW = 500-8.000).

Granted: 1994-05-03
Abstract: Abstract of the Disclosure A position estimation apparatus is adapted to estimate the position of a target in the steps as will be set forth below.  The target is observed four or more times by an image sensor during a lime period in which the target and movable body unit move in those directions not parallel to each other.  Acceleration is applied to an accelerator at least once at a time between the observation times.  Two-dimensional angle information of the target's azimuth and elevation angles is detected from the image information of the target acquired by the image sensor at the time of observation. A coordinate system of the movable body unit is found in accordance with the position and attitude information of the movable body unit, and the two-dimensional angle information of the target is plotted on the coordinate system.  Simultaneous equations are prepared by sequen-tially substituting the two-dimensional angle informa-tion of the target obtained through the observation into an equation of motion representing a regular motion of the target initially entered on a position estimation apparatus.  Parameters in the equation of motion is found from the simultaneous equations.  The position of the target at a given time is estimated by substituting the parameters into the equation of motion and the given time into the latter equation.

Abstract: Spread spectrum chirps (i.e., wideband frequency packets) are propagated on a local area network in a hostile communications environment, such as a powerline or a crowded radio frequency band. chirps are self-synchronizing, data bit (or subdata bit) in length and detectable by all network nodes, to allow the contention resolution and collision detection needed to support carrier-sense based network protocols. A matched filter of the same time length and encoding sequence as the transmitted chirp provides the self-synchronized chirp reception at each receiver.
