Abstract: The present invention relates to systems and methods for solid freeform fabrication, especially fused deposition modeling, as well as various articles made using the same, where the systems and methods utilize certain thermoplastic polyurethanes which are particularly suited for such processing. The useful thermoplastic polyurethanes are derived from (a) a polyisocyanate component, (b) a polyol component, and (c) an optional chain extender component where the resulting thermoplastic polyurethane has a crystallization temperature above 80° C. and retains more than 20% of its shear storage modulus at 100° C. relative to its shear storage modulus at 20° C.

Abstract: A well completion and related method are provided for formations susceptible to simultaneous production of oil and water. In one embodiment, two closely spaced, preferably horizontal wellbores are drilled from a single well into the reservoir. The reservoir rock surrounding one leg (typically the upper leg) is chemically treated to make it hydrophobic, whereas the reservoir rock surrounding the other leg is chemically treated to make it hydrophilic. Separate production tubing and a dual completion is installed in order to enable independent flow from each leg. Drawdown pressures in both legs are controlled to be sufficiently close to each other such that only oil flows into one leg and only water into the other. The water produced is re-injected downhole or brought to the surface.

Abstract: A drill bit system for a drilling assembly is disclosed. The drill bit system may include a chassis, a head, and one or more compliantly coupled gauge pads. The head may include a first plurality of cutters coupled with an end of the head, and the head may be coupled with chassis. The one or more gauge pads may include a second plurality of cutters, and the one or more gauge pads may be movably coupled with the chassis.

Abstract: Apparatus and processes for luring and trapping insects using an olfactory and/or visual attractant. The apparatus generally having a protective housing or frame, an olfactory attractant defining a lure, and at least one dual or multiple-sided adhesive panel. The housing or frame contains and protects the olfactory attractant and adhesive panel from contacting other surfaces and permits the adhesive panel to form at least a portion of an outwardly exposed or exterior surface of the trap apparatus.

Abstract: A dispenser for broadcasting a scent is particularly useful in connection with insect pheromones, a quantity of volatile pheromone carrying substance is packaged as a solid or gel in a hollow tube. A carrier can be provided for the tube, having a surface to which the tube is to be affixed with the longitudinal axis of the tube substantially parallel to the surface of the carrier, and the tube being disposed directly on the surface of the carrier. The carrier has at least one air circulation opening aligned perpendicular to the longitudinal axis of the tube and one or more stops preventing relative displacement of the tube and the carrier. Preferably, the carrier is a one piece integrally molded thermoplastic panel, with retaining clasps projecting from a planar body and adapted to bear diametrically inwardly on the tube. The length of the tube and dimensions of the carrier are such that the tube positively remains captive.

Abstract: A lure container for holding a scented lure in an insect trap includes a basket formed by spaced apart webs defining a volume of space for enclosing the lure. The volume is a truncated conical section and the basket has a wide opening at one end of the section. Attached to a top peripheral edge of the basket is a lid that is hinged along one section of the edge. The opposite edge has a tab that extends outwardly for mounting the basket in the trap. The basket and lid are both formed by spaced apart webs and ends of the webs of the lid extend into space in the webs of the basket, to block the opening and confine the lure. The lure container or basket is placed in the housing of an insect trap wherein the basket is spaced away from all of the interior walls of the trap by the tab extending from the peripheral edge of the basket.
