Abstract: The present invention provides a microfluidic system (100) for fast, accurat e and low cost electrophoretic analysis of materials in the fields of chemistry, biochemistry, biotechnology, molecular biology and numerous other fields. Light from periodically spaced regions along a channel (110) in the microfluidic system are received by the photodetector (130). The intensity of light received by the photodetector is modulated by the movement of species bands (123) through the channel under electrophoretic forces. By Fourier analysis, the velocity of each species band (123) is determined and the identification of the species is made by its electrophoretic mobility in the channel (110).

Abstract: This invention relates to processes for the production of symmetrical polyurea-urethane coated granular fertilizer products, and to the symmetrical polyurea-urethane coated granular fertilizer products produced by these processes. These processes comprise coating fertilizer granules with compounds which react to form urethane coatings which contain terminal isocyanate groups, followed by polymerization of these urethanes to form symmetrical polyurea-urethanes. Suitable compounds comprise a) an organic polyisocyanate component, and b) an alkanol-amine component containing at least one tertiary amine group and at least one hydroxyl group. These compounds are present in sufficient quantities that the molar ratio of isocyanate groups to isocyanate-reactive groups is from about 1.6:1.0 up to about 10.0:1.0 in each encapsulating layer. It is necessary that sufficient amounts of these compounds are applied to the fertilizer granules such that the symmetrical polyurea-urethane coated granular fertilizer particles contain from about 0.5 to about 15% by weight of polyurea-urethane, based on the total weight of the encapsulated fertilizer particles.

Abstract: A shared memory multiprocessor (SMP) data processing system includes a store buffer implemented in a memory controller for temporarily storing recently accessed memory data within the data processing system. The memory controller includes control logic for maintaining coherency between the memory controller's store buffer and memory. The memory controller's store buffer is configured into one or more arrays sufficiently mapped to handle I/O and CPU bandwidth requirements. The combination of the store buffer and the control logic operates as a front end within the memory controller in that all memory requests are first processed by the control logic/store buffer combination for reducing memory latency and increasing effective memory bandwidth by eliminating certain memory read and write operations.

Abstract: An apparatus and method for the nondestructive inspection of dielectric matierals are disclosed. Monochromatic, phase coherent electromagnetic radiation (6), preferably in the 5-50 gigahertz frequency range (i.e. microwaves) impinges on the sample. In accordance with Snell's law, the microwaves are partly transmitted and partly reflected at each interface whe re the dielectric constant changes due to irregularities. A portion of the reflected beam is combined with the signal reflected by the specimen being inspected. These two signals have the same frequency, but may differ in amplitude and phase. The signals combine to produce an interference pattern, a pattern that changes as the specimen changes, or as the position of the specimen changes relative to a detector (2, 4). A computer (10) is programme d to distinguish features in the interference pattern attributable to irregularities in the material from features in the interference pattern attributable to sources of noise.

Abstract: A method of managing objects within the simulation model commences with the storage of a first value for a particular parameter within an object of the simulation model. A panel is then displayed within the user interface. The relevant parameter of the above-identified object may then be identified for inclusion within this panel. In response to the identification of the parameter, an identifier (such as an icon) associated with the parameter is displayed within the panel. A second value for the relevant parameter of the object may then be inputted by a user via the panel. The second value for the parameter is then stored separately from the first value for the parameter, and these first and second values can be selectively applied to the parameter.

Title: Apparatus for regulating heater cycles to improve forced-air heating system efficiency
Inventor: HAMMER JACK
IPC: F23N5/26
Filed: 1999-03-25
Granted: 2007-07-10
Abstract: A method and apparatus of regulating cycles of a burner in a forced air heating system. A control unit uses a sensor at an output of a heat exchanger to make measurements of a temperature of air output from the heat exchanger. The control unit observes temperature measurements, after the burner has turned on. It initializes a confirmation interval when two consecutive temperature measurements are the same, if the temperature is the same at an end of the confirmation interval.  The invention interrupts firing of the burner for an interrupt interval. The interrupt interval is insufficient to allow the heat exchanger to cool below a temperature useful for heating below which the circulation fan would shut off.

A collecting chamber between the discs has a bottom wall defining an upper limit of the treating chamber, the discs having filtering surfaces comprising textile fabric with micro-perforations. Sealing means are between the peripheral rims of the discs and the partially cylindrical wall. This arrangement prevents loss of hydraulic pressure within the treating chamber and allows the flow rate of the treated liquid to increase.
