Title: Electronic support measures (esm) duty dithering scheme for improved probability of intercept at low esm utilization
Inventor: LEWIS WILLIAM L
IPC: G01S13/86
Filed: 1999-10-20
Abstract: A duty dithering method for use with electronic support measures and radar warning receivers, and the like, that provides for improved probability of intercept at low utilization levels. The electronic support measures (ESM) system and radar warning receiver are controlled by a multi-system sensor manager having an ESM scheduler. In accordance with the present method, a maximum duty cycle is chosen for the ESM  system. The chosen duty cycle is allocated to the ESM system each frame by the ESM scheduler. At the beginning of each frame, the ESM scheduler picks a random offset and subtracts it from the maximum duty to compute an ESM duty for that frame.      The ESM scheduler commands data collections based on the computed duty for that frame. This step is repeated each frame.

Title: A method of recycling mixed colored cullet into amber, green or flint glass
Inventor: MOSCH DUANE A
IPC: C03B23/00
Filed: 1997-12-17
Abstract: Mixed colored cullet glass, which generally contains amounts of green, amber and flint (colorless) glasses, is recycled into amber colored glass by regulating the additive amounts of iron, carbon, sulfur, and sulfur compounds in the mixture to impart the desired reddish-brown hue. The color green may be selectively decolorized from the mixed colored cullet and the mixed colored cullet may be colorized for the color amber, thereby rendering the decolorized mixed colored cullet substantially amber colored for use in amber colored glass production, such as carbon-sulfur soda lime amber glass. The technique of the invention is also used to produce recycled green or flint glass from unsorted mixed colored cullet glass. The invention is particularly useful in producing amber colored containers or bottles for beverages that require protection from the deteriorating effects of light, such as beer.

Patent CA-2331588-A1 (CA)
Title: Fluid flow control in curved capillary channels
Inventor: REISER WOLFGANG OTTO LUDWIG
IPC: B01L3/00
Filed: 2001-01-22
Abstract: A capillary pathway is dimensioned so that the driving force for the movement of liquid through the capillary pathway arises from capillary pressure. A plurality of groups of microstructures are fixed in the capillary pathway within discrete segments of the pathway for facilitating the transport of a liquid around curved portions of pathway. Capillary channels can be coupled between two adjacent groups of microstructures to either the inner and outer wall of the capillary pathway. The width of each capillary channel is generally smaller than the capillary pathway to which it is connected, and can be varied to achieve differences in fill initiation. The grouped microstructures are spaced from each other within each group on a nearest neighbor basis by less than that necessary to achieve capillary flow of liquid with each group. Each group of microstructures are spaced from any adjacent group by an inter-group space greater than the width of any adjacent capillary channels connected to the capillary pathway. Generally, the microstructures are centered on centers which are equally spaced from each other, and microstructures that are located closer to the inner wall of any curve in the capillary pathway are generally smaller than the microstructures located closer to the outer wall. This combination of structural features causes fluids to flow through the capillary pathway so that the rate of flow is somewhat non-uniform as the fluid travels around curved portions of the capillary pathway, the meniscus appearing to pause momentarily at each inter-group space, the flow being somewhat slower near the inner wall of a curved portion than near the outer wall.

Patent CA-2332685-A1 (CA)
Title: Field upgrading of heavy oil and bitumen
Inventor: ABDEL-HALIM TAYSEER
IPC: C10G21/00
Filed: 2001-01-30
Abstract: A process and system which integrates on-site heavy oil or bitumen upgrading and energy recovery for steam production with steam-assisted gravity drainage (SAGD) production of the heavy oil or bitumen. The heavy oil or bitumen produced by SAGD is flashed to remove the gas oil fraction, and the residue is solvent deasphalted to obtain deasphalted oil, which is mixed with the gas oil fraction to form a pumpable synthetic crude.      The synthetic crude has an improvement of 4-5 degrees of API and lower in sulfur, nitrogen and metal compounds. The synthetic crude is not only more valuable than the heavy oil or bitumen, but also has substantial economic advantage of reducing the diluent requirement since it has lower viscosity than the heavy oil or bitumen. The asphaltenes, following an optional pelletizing and/or slurrying step, are used as a fuel for combustion in boilers near the steam injection welts for injection into the heavy oil or bitumen reservoir. This eliminates the need for natural gas or other fuel to produce steam at reservoir location and thus improves the economics of the heavy oil or bitumen production substantially. Alternatively, the asphaltenes are used as a feedstock for gasification to produce injection steam, synthesis gas. The CO2 could be used as additive with injection steam to enhance the performance of SAGD and the hydrogen could be exported to nearby processing facility. The invention upgrades the heavy oil or bitumen to a synthetic crude of improved value that can be pipelined with reduced amount of diluent, while at the same time using the asphaltene fraction of the residue for combustion to fulfill the energy requirements for generating injection steam for SAGD.
