Title: Resource allocation arrangement
Inventor: DUFFANY JEFFREY LOUIS
IPC: G06Q10/06
Filed: 1990-01-24
Granted: 1998-07-07
Abstract: A method for allocating resource use to a process having a plurality of tasks in which a set of signals identifying the interferences in resource use among the plurality of tasks is generated and a signal representing an initial non-interfering allocation is produced. The allocation signal is iteratively improved by 1) determining the correlations among the identified interferences, 2) comparing the determined correlations to prescribed criteria, 3) modifying the allocation signal in accordance with the determined correlations, and 4) reforming the interference signal set responsive to the determined correlations, When the determined correlations meet the prescribed criteria in the correlation determination, the correspondingallocation signal is selected as the optimum non-interfering allocation.

Title: Method and apparatus for detecting surface flaws in electrical cable plastic jacketing
Inventor: LAGROTTA RICHARD T
IPC: G01N19/08
Filed: 1990-03-28
Granted: 1993-10-05
Abstract: METHOD AND APPARATUS FOR DETECTING SURFACE FLAWS       IN ELECTRICAL CABLE PLASTIC JACKETING Abstract This invention employs principles associated with air-lubricated thrust bearings, to provide highly sensitive indicators of the presence of defects along the surface of a cable insulative layer. A spring-loaded mounted probe containing anaxial air passage is closely directed at the cable surface. The cable is moved linearly under the probe, and air is introduced to create air flow at and along the surface in the vicinity of the probe's outlet oriface. The static pressure at the probe outlet oriface is essentially constant, until a surface defect such as a scratch or a protrusion causes a substantial change in the air pressure or air flow rate. The change is detected and recognized as an indication of defect.

Title: Process and device for continuous extraction and analysis of fluid using membrane
Inventor: PAWLISZYN JANUSZ
IPC: B01D61/24
Filed: 1993-04-13
Granted: 1999-07-13
Abstract: A process and a device for the continuous extraction and analysis of chemical substances from solute fluid using membrane is characterized by passing solute fluid 14 through housing 20 on one side of a semipermeable structure 19 and simultaneously passing extracting fluid 11 through the housing on the other side of the semipermeable membrane structure. Substances passing from solute fluid through the semipermeable membrane structure into the extracting fluid are delivered by the extracting fluid as carrier, into a sorbing phase 27. Cooling 28 and heating 24 of the sorbing phase allows substances to be concentrated and detected by detector 50 and to be continuously monitored. Extracting fluid may be a gas or a pressurized dense gas. Extraction using pressurized dense gas and membrane is achieved by maintaining the pressure of the solute fluid and the pressurized dense gas within a high pressure housing substantially equal. Previously, solute fluids were analyzed using batch processes with liquid-liquid extraction, extraction cartridges or purge and trap. Continuous extraction and analysis using membranes eliminates the use of organic solvents and provides inexpensive and continuous monitoring of volatile, semi volatile, non-volatile and polar compounds in water and other fluids.
