Abstract: A process is provided for documenting the contents of at least one version of a plurality of data products stored in a database, at least one of the products being a composite product having at least a portion of at least one of the data products included therein. The process includes the steps of: creating a state file to be associated with a version of a composite product to be created, the state file specifying a selected version of at least one selected data product to be used in creating the composite product; using the state file to access the selected version of the selected product from the database; creating the version of the composite product by including therein at least a portion of the selected version of the selected product; and generating a state history file associated with the version of the composite product, the state history file indicating that at least a portion of the selected version of the selected product is included within the version of the composite product.

Abstract: A process for compressing a two dimensional array of data including at least one array block having a plurality of block rows and a plurality of block columns of pixels, each pixel having at least one associated intensity value. The process includes generating a delta frame associated with a pair of the block columns, the delta frame having a plurality of delta rows and delta columns of delta bits, one of the delta rows being a highest order row; determining a number of duplicate rows of the delta rows, each of the duplicate rows forming an identical row byte value having delta bits which have a predetermined relationship with the delta bits of the highest order row; recording information indicative of the number of duplicate rows; and developing compressed data including the information indicative of the number of duplicate rows of the delta frame.

Abstract: Using component-level test data to reduce system test. By modeling a system, sensitivity analysis reveals critical components and parameters of those components required to meet system performance parameters. Critical components are tested for these parameters, and these measurements associated with the components. Systems may be assembled which are modeled to meet the system performance parameters based on the model and the measured parameters. Systems may be assembled and calibration coefficients derived and applied from the model and the measured parameters.

Abstract: A fluid intake pressure regulating system of this invention maintains the pressure of fluid entering a pump below a preselected level for avoiding undesirably high fluid discharge pressure exiting the pump.

Abstract: A pumping system for pumping liquid with entrained intermittent volumes of gasses. The pressure downstream of the pump is measured and the speeds of the engine and pump are controlled in response pressure changes downstream of the pump by a controlling element overriding a governor of the engine.

Abstract: The present invention concerns finely divided particles of compounds that provide flame retardancy and/or smoke suppressant properties to fibers, textiles, polymeric articles, paper, paint, coating and insulation. More particularly, the present invention concerns colloidal-sized particles of hydrated salts, organic phosphates, metal borates, polyamides, solid halogenated flame retardants with a melting point greater than 250.degree. C., molybdenum compounds, metallocenes, antimony compounds, zinc compounds, bismuth compounds and other solid chemicals which act as flame retardants or smoke suppressants. The present invention also concerns various milling processes to reduce these materials to colloidal sizes and to disperse them in water, organic liquids and meltable solids.

Abstract: A process for passivating contaminating metal on a hydrocarbon cracking catalyst is provided. The catalyst is contacted within a hydrocarbon catalytic cracking unit with a stabilized dispersion. The dispersion comprises a fluid vehicle, a dispersion agent, and finely milled particles of one or more metals or metal compounds for passivation of metal-contaminated cracking catalysts. The dispersion is preferably produced by a process wherein an agitated media mill is loaded with comminuting media, fluid vehicle, dispersion agent and particles of a metal or metal compound for passivation of metal-contaminated cracking catalysts. The comminuting media, fluid vehicle, and particles are then agitated until the particles are reduced in size by at least 10% and have a volumetric average particle size of less than 0.5 microns.

Abstract: A multipolar joint endoprosthesis for joint replacement includes multiple wedge shaped, cylindrical components attached in sequence to proximal and distal components (designed to be affixed to bone) each inseparable except by surgical manipulation and each freely, passively rotating about axes perpendicular to its planes of effacement with adjacent components. This passive rotation of one or more of the wedge-shaped components alters the angular orientation of the proximal and distal components thereby allowing range of motion of the joint in question.
