Abstract: Methods and systems for producing hydrocarbons. An example method includes producing a non-hydrocarbon liquid from a first horizontal wellbore, the first horizontal wellbore extending from a vertical wellbore and through a hydrocarbon producing formation. The method further includes pumping the non-hydrocarbon liquid with a first pump into a second horizontal wellbore, the second horizontal wellbore extending from the vertical wellbore and disposed downhole and underneath the first horizontal wellbore. The method additionally includes pumping a hydrocarbon liquid uphole to a surface with a second pump disposed downhole of the first horizontal wellbore.

Abstract: Systems and methods can support complex event handling. A complex event handler can receive a current event. The current event may be stored to an event log. The current event may be matched against rule conditions within a rule implementation system. Prior events may be identified, within the rule implementation system, upon which the matched rule conditions also depend. The event log may be searched for the identified prior events. Prior event parameters, corresponding to the identified prior events, may be retrieved from the event log. The rule conditions may be evaluated in view of the current event and the retrieved prior event parameters. Actions may be executed that correspond to the rule conditions triggered in response to the evaluating. Domain specific language expression may be received, processed, and incorporated as rules and facts into the rule implementation system.

Abstract: Systems and methods can support efficient graph-based rule engines for complex, dynamic, unstructured data. The system can provide an interface to a graph database for storing rules and facts. The system can receive rules and facts. The system can convert the received rules to a format suitable for insertion into the graph database and store the converted rules into the graph database. The system can receive a question and perform a query against the graph database to evaluate rules and facts in light of the received question. The system can return facts retrieved from the graph database in response to the performed query. Also, the system can generate one or more actions based upon facts retrieved or rules trigger in response to the performed query.

Abstract: A mar-free mounting for a wheel balance weight has a clip cast into the weight, the clip having a U-shaped portion fit over a wheel rim flange. A convexly curved hemmed edge is formed at the leading edge of the clip which moves into a complementary groove formed in the surface of the wheel rim flange when the clip is installed. The hemmed edge is configured to wedge into the groove, establishing an increased circumferential frictional force and a high locking force which is primarily relied on to secure the weight. Installation and removal thus involve only modest contact loads, which together with the effect of the hemmed edge being smoothly curved at either end prevent marring of painted or clear coated wheel surfaces.

Abstract: A vehicle wheel cover includes a cover body having apertured flange portions arranged in diametrically opposite pairs. A leaf spring extends between each pair of apertured flange portions and includes shoulder means projecting radially outwardly of the flange portions for cooperative engagement with abutment means of a wheel opening. The leaf springs are in overcenter relationship to the cover body to provide a spring force resisting radial inward movement of the shoulder portions thereof.

Abstract: A vehicle wheel cover assembly includes a lightweight molded plastic cover member having a series of axial inwardly extending flanges which are apertured. The wire ring assembly includes cantilevered loops having bight portions which extend outwardly through the openings of the flanges to retain the wire ring assembly to the wheel. Additional bight portions of the loops engage the flanges of the cover member to clamp these flanges to the wheel.

Abstract: A vehicle wheel cover includes a cover body of plastic material having a plurality of integral extensions, each having a relatively thin body portion adjacent the cover body and a thicker terminal portion. A stiff ring interconnects the terminal portions of the extensions and is secured thereto by clips, each of which includes retaining fingers, for retaining the cover to a vehicle wheel.

Abstract: Apparatus is disclosed for attaching a flexible annular member to a rigid member using an annular tongue on an annular bead on one of the members that is engageable in an annular groove in an annular bead on the other member, and further using a preformed resilient lock ring that is split so as to have oppositely facing ends and has a C-shaped cross-section with a radially outwardly facing peripheral side so as to be mountable over and then clamp together and hold the beads on the members with their tongue and groove engaged.

Abstract: A vehicle wheel cover includes a plastic cover body and an annular retention band which is secured to the cover body by a series of projections on a flange of the body being received through openings in the band. The material of the openings is formed into integral lanced tabs which engage shoulders of the projections. The axial extent of the openings is greater than that of the projections to permit axial adjustment of the cover body and retention band relative to each other. The band is provided with retaining fingers for retaining engagement of the cover on a vehicle wheel.

Abstract: A cast vehicle wheel includes a series of circumferentially spaced radially extending reinforcement ribs. A number of adjacent pairs of ribs are provided with ramps which slope axially and radially opposite to each other, with one such ramp including a retention notch. The cover includes a number of radially flexible box members including a base wall slidably engageable with one of the ramps and a retention lip slidably engageable with the other ramp and interlockingly engageable with the retention notch. The box member is twisted until the retention lip slides past the other ramp and into engagement with the retention notch.

Abstract: A plastic vehicle wheel cover includes a cover body provided with integral elongated slightly tapered tubular extensions, each being slotted, to provide a plurality of cantilevered fingers which are provided with abutments which snap into a circumferential groove in a lug nut to mount the cover on a vehicle wheel.

Abstract: A plastic wheel cover is provided with a plurality of recesses opening to a flange of the wheel and the tire bead when the cover is assembled to the wheel. Each recess houses a generally C-shaped clip having a body portion fitting within the opening of the recess and return bent leg portions locked between end walls of the recess and a transverse intermediate wall. Axially spaced rows of teeth on the body portion engage the tire bead and flange of the wheel to retain the cover to the wheel.

Abstract: A vehicle wheel cover is retained on a vehicle wheel by a plurality of cantilever type retainers having teeth which engage both a flange of the wheel and the tire bead seat. The retainers are removably attached to the cover body and are pre-shaped to a slightly arcuate configuration prior to assembly of the cover to the wheel to provide for ease of assembly together with low stress and a high load.

Abstract: A wheel cover is retained on a vehicle wheel by a pair of semi-annular shoes which are located inwardly of an axial flange of the wheel cover and engage both this flange and the wheel to floatingly retain the cover on the wheel.

Abstract: A tapered shank ball stud, as used in an articulated joint assembly, has its tapered shank secured in seated engagement in the tapered aperture of a support member in such an assembly by a lock nut threaded onto the externally threaded end of the ball stud with a collapsing washer of original C-shaped annulus configuration sandwiched between the member and the lock nut, the washer being operative as the nut is driven onto the ball stud to effect axial movement of the ball stud to fully seat the tapered shank portion thereof in the tapered aperture in the support member thereby preventing rotation of the ball stud as the lock nut is torqued down to effect collapsing of the washer into a final flat ring-like washer configuration.
