Abstract: A flow restrictor is provided for a lubrication circulation system. The flow restrictor comprises a body configured to obstruct a flow of lubricant within the lubricant circulation system. The body has one or more through holes communicating with upstream and downstream portions of the lubrication circulation system. Each of the one or more holes has a cross-sectional area sufficiently small, and a length sufficiently long, to prevent turbulent lubricant flow therethrough at temperatures below a first predetermined reference temperature. The one or more holes have sufficient aggregate cross-sectional area to allow a desired lubricant flow rate through the body at temperatures at or above a second predetermined reference temperature.

Abstract: A bi-layer, woven geotextile fabric has interwoven first and second layers. The first layer is over and under woven through the second layer in a pre-determined pattern so that the first layer has portions which face a first side of the second layer and portions which face a second side of the second layer. Monofilaments in the warp direction of the first layer have a predetermined differential heat shrinkage characteristic that is greater than the monofilaments in the warp direction of the second layer. Closed cells defined by the pattern of the over and under weave are disposed on the first and second sides of the second layer. Shrinkage of the monofilaments in the warp direction of the first layer provide for a separation of a portion of the second layer from the first layer at the cells.

Abstract: A window frame is manufactured as an integral unit comprising a frame body, at least one nailing flange secured to the frame perimeter, and a strip of tape secured to the nailing flanges with the outer portion of the tape extending beyond the outer edge of the flange. In another embodiment, individual nailing flanges are manufactured and delivered on site, including a strip of tape secured to the nailing flange with an outer portion of the tape extending beyond the outer edge of the flange The installer first secures such pre-taped flanges to the window frame body, before nailing the resulting window frame unit to the wall. With both embodiments, the window frame unit is first fit into the window penetration in the wall, with the nailing flanges and tape overlapping the wall. Each flange is nailed to the wall by folding back the outer, unattached portion of the tape, thereby exposing the nail holes on the flange, and driving nails there though into the wall. The backing on the folded outer portion of the tape is removed, exposing the adhesive side, which is then laid over the remainder of the flange to cover the nails and over a portion of the wall immediately surrounding the outer edge of the flange.

Abstract: A hierarchical decoder is operable to decode a hierarchical multi-layer data package. The hierarchical multi-layer data package includes a plurality of layers and one or more subpackages in each layer. To decode the data package, an objective function is created based on parameters for identifying data in the data package most relevant to information of interest. Subpackages in one or more layers are evaluated using the objective function and a subpackage is selected. Information for the selected subpackage, which may include a summary and metadata, is used to determine whether the subpackage satisfies an information need. If the information need is not satisfied, a drill down procedure is performed to evaluate subpackages in a next lower layer of the data package.

Title: Hybrid strategies for reducing leaching of metal biocides from biodegradable substrates
Inventor: KEEN BRIAN T
IPC: B27K3/16
Filed: 2009-03-12
Granted: 2017-10-31
Abstract: Hybrid strategies generally involve treating biodegradable substrates with preservative compositions having at least two phases in which the metal biocide is distributed among at least the two phases and via equilibrium reactions moves between the two phases. Both phases are caused to contact the substrate in a manner so that the phases are in contact with each other during at least a portion of the treatment. In illustrative embodiments, the first phase is a liquid phase comprising complexed metal biocide dissolved in a liquid carrier, while the second phase comprises particles comprising the metal biocide, often precipitated and/or colloidal particles. The strategies and related compositions, processes, and treatments are hybrid in the sense that the strategies include both heterogeneous (insoluble) and homogeneous metal biocide constituents. Unlike heterogeneous strategies, hybrid strategies are less sensitive to particle size constraints and may use biocide particles with a wider range of particle sizes. Unlike homogeneous strategies, hybrid strategies are less sensitive to pH and may use a wider range of complexing agents, including mildly alkaline amines such as triethanolamine.

Abstract: Disclosed are methods for improving the production of heavy/viscous crude oil from subterranean formations com-prising secondary production through use of a displacement fluid (typically a waterflood) wherein the subterranean formation is subjected to cyclic periods of overinjection of the displacement fluid followed by underinjection of the displacement fluid, but keeping the overall cumulative voidage replacement ratio (VRR) within a defined range, typically targeted to be about 1. In some aspects, the initial production of such heavy/viscous crude oil is limited, if possible, followed this cyclic secondary production methodology. By keeping the initial production, VRR, and cumulative VRR in defined ranges, the expected ultimate recovery (EUR) can be optimized, and overall production increased for example by as much as 100% or more relative to conventional pro-duction methods.
