Title: Head for high performance internal combustion engine
Inventor: SMITH RICHARD W JR
IPC: F02B75/18
Filed: 1986-01-03
Granted: 1994-08-02
Abstract: IMPROVED HEAD FOR HIGH PERFORMANCE     INTERNAL COMBUSTION ENGINE                             Abstract An improvement in a cast head for a high performance internal combustion engine of the type having a flat mounting surface and having, for each of several in-line circular piston areas, a wedge type combustion chamber extending from the head mounting surface and defined by a flat quenching surface and a concave, contoured wedge-shaped cavity forming surface.  This wedge shaped cavity tapers outwardly from the quenching surface between a shallower portion adjacent the quenching surface to a deeper portion in which the valves are located.  The improvement in this type of head includes providing the cavity forming surface the deeper area of the combustion chamber with a general contour of the type defined by two parallel intersecting, truncated cones gen-erally concentric to the two valve openings in the wedge shaped combustion chamber with a gradually contoured surface section be-tween the cones at the deeper area of the combustion chamber and a velocity increasing protuberance in the combustion chamber at the shallower portion of the cavity which protuberance includes a curved edge portion of the flat quenching surface, which edge portion extends inwardly of the wedge shaped cavity toward a posi-tion between the two valve seats and a built up mass of cast ma-terial sloping from the curved edge of the quenching surface toward the valve seats to guide gases from the combustion chamber through the exhaust outlet primarily and, to a lesser extent from the intake inlet into the combustion chamber.  This velocity increasing mass of material adjacent the exhaust port of the combustion chamber in-creases the velocity through the exhaust port during the exhaust cycle of the internal combustion engine.  Another improvement in-volves restricting the inlet passage for directing atomized fuel to the intake valve and then into the combustion chamber.  This restriction increases velocity during the intake cycle of the in-ternal combustion engine.

Title: Collision detection technique for an optical passive star local area network using csma/cd
Inventor: KAVEHRAD MOHSEN
IPC: H04L12/44
Filed: 1987-06-29
Granted: 1990-12-18
Abstract: A COLLISION DETECTION TECHNIQUE FOR AN OPTICAL PASSIVE STAR LOCAL AREA NETWORK USING CSMA/CD            Abstract The present invention relates to a collision detection technique for an optical Star LAN using CSMA/CD. The present technique is implemented by preferably adding two or more fixed Hamming weight sequences, e.g., a fixed even or odd number of 1's in each unique cyclic error correcting code word, to the preamble section of each packet of information to be transmitted. These collision detection sequences have a length which is beyond the vulnerable time period of the CSMA/CD protocol (maximum round-trip propagation delay for each packet) by at least one code word length in order to prevent any misdetection, or false detection, of a collision. Each receiver in the listeningperiod, looks for a code pattern with a fixed Hamming weight. When code patterns collide, the Hamming weight of the resulting code word in the collisionperiod will exceed the nominal sequence weight (will include more 1's than the fixed Hamming weight) and a sequence weight violation is detected. Such detection is used to stop the transceivers from transmitting over the LAN and restart the network in order to avoid further collisions and network chaos.

Granted: 1993-08-31
Abstract: TITLE POLYIMIDE GAS SEPARATION MEMBRANES    ABSTRACT OF THE DISCLOSURE Semi-flexible aromatic polyimides, prepared by polycondensation of dianhydrides with diamines having alkyl substituents on all ortho positions to the amine functions, or with mixtures of diamines, some components having substituents on all positions ortho to the amine functions, are disclosed. Membranes formed from this class of polyimides have improved environmental stability and superior gas permeability.  The range of gas permeation properties observed allows for the tailoring of membrane material for widely diverse gas separations.  The high permeabilities of some gases from multicomponent mixtures is due to the optimization of the molecular free volume in the polymer.

Title: Rotary processor for plastic and polymeric materials providing surge compensation
Inventor: MEHTA PRADIP S
IPC: B29C48/03
Filed: 1988-02-02
Granted: 1991-07-09
Abstract: ABSTRACT      A rotary processor has enclosed processing passages defined by channels in the rotor and a stationary coaxial closure.  At least one processing passage is used as a stabilizing passage and another as a metering passage, whose volume and cross section are less  than  the stabilizing  passage.   A  feed  of  plastic  or polymeric  material  enters the stabilizing passage and may be subject  to  fluctuations  or  disturbances  arising  in  external upstream equipment or within upstream stages of the processor itself.  Substantially all material in the stabilizing passage is diverted through a first transfer passage to an entrance into the metering passage.  An adjustable metering (throttling) element allows  a  controlled  first  flow  of  material  to  be  carried downstream  through  an  adjustable  gap  between  this  metering element and the bottom of the metering passage.  This controlled first flow is discharged for providing material having uniform flow or at least a marked reducton in such fluctuations and disturbances.  The excess material which does not pass through the adjusted gap forms a recycled second flow which is returned back through a second transfer passage into said stabilizing passage for recycling.  A modified embodiment shown as metering pumping  apparatus  includes  pairs  of stabilizing and metering passages   sharing   in  handling  throughput with  adjustable throttling  means  for  each  metering  passage.   Interconnecting transfer  passages  equalize  operation  among  these  pairs.   A transfer passage  is  also  shown  extending  from  an  upstream processing  passage  to  and  past  a  metering  passage  to  a stabilizing passage.
