Abstract: A device determines the specific gravity of a wellbore fluid flowing into a submersible pump. The specific gravity of the wellbore fluid is determined by measuring the pressure increase across at least two pump stages and then using fluid flow properties and known pump characteristics to back calculate the specific gravity of the wellbore fluid.

Abstract: A die cast aluminum front cover plate for application in a vane-type camshaft phaser includes a plurality of bores and a plurality of steel threaded inserts press fitted into the bores. Steel threaded inserts add the required strength to the stator bolt threads to enable a shorter thread engagement, which in turn enables a thinner aluminum front cover plate that may be packaged in tight applications where prior art aluminum front covers cannot be used due to their larger thickness. The steel threaded inserts not only provide a higher stiffness but also have a flanged shape that effectively spreads the clamp load generated during the tightening of the stator bolts further out preventing local clamp load points and, consequently, reducing cover deflection over the span of the front cover plate.

Abstract: A detector for detecting vapors emitted from analytes includes a housing, a pump and a sensing assembly. The housing has an inlet, an outlet and an enclosed sensing volume therebetween. The pump communicates with the housing for moving a carrier sequentially through the enclosed sensing volume at a predetermined flow rate. The sensing assembly senses the vapors of the analyte delivered by the carrier as the carrier passes through the housing. The sensing assembly includes a sensing unit constructed of an amplifying fluorescent polymer, a source of excitation, a detector, and a convertor assembly.

Abstract: A torque bias coil spring for a camshaft phaser disposed in an annular well formed in the phaser rotor and having a central arbor for supporting the spring. The radius of the central arbor is such that the spring has radial operating clearance of 5-10%, as in the prior art. However, the improved arbor includes regions of higher radius at the arbor ends supporting the innermost and outermost coils of the spring. These regions serve to prevent the spring from being laterally displaced during torsional motion, thus minimizing the relative motion at the spring contact points, reducing stress on the spring, and improving the efficiency of the spring by reducing frictional hysteresis.

Abstract: A system for providing reliable, unalterable mechanical data associated with the mechanical properties of a concrete mass. The system includes a logger, a second memory device and an outbound data transfer device. The logger is provided with one or more sensors, a microprocessor and a first memory device. The one or more sensors measure physical properties of the concrete mass and generate data associated with the physical properties. The microprocessor receives the data from the sensor and calculates maturity data and mechanical strength data. The first memory device stores the mechanical strength data within the concrete mass in an unalterable form. The second memory device is located outside the concrete mass. The outbound data transfer device transfers the mechanical strength data from the first memory device to the second memory device.

Abstract: A valve lifter assembly for deactivating a cylinder in an internal combustion engine. The valve lifter assembly is provided with a plunger movably disposed within a bore of a main body member to controllably isolate the cam lift from the rocker arm and valve of the engine. The plunger is normally locked in an extended position to transmit cam lift to reciprocatingly operate the valve. At least one locking pin is moveably disposed within the plunger to engage an inner annular groove of the main body member. Pressurized oil is provided to dislodge the locking pins from the annular groove and allow the plunger to move within the main body member, thereby isolating the cam lift from the rocker arm and valve. The deactivating lifter is preferably disposed within the recess conventionally provided for hydraulic valve lifters.

Abstract: A method and apparatus for selective routing of a multi-recipient communication from an origin domain to a destination domain within a communications network. An exit routing station added to the origin domain receives a datagram including content data intended for multi-recipient delivery in the destination domain. The exit routing station modifies the datagram for routing to the destination domain, and transmits it to the entry routing station. This enables delivery to the destination domain by other than multi-recipient techniques. An entry routing station added to the destination domain modifies the datagram for multi-recipient delivery in the destination domain and initiates multi-recipient delivery. The destination domain's entry routing station may modify the datagram with information specific to the destination domain and unknown to the origin domain.

Abstract: A well pump has a riser gas separator for removing large slugs of gas prior to reentry into the pump. The riser extends upward from a barrier that is located in the well. The riser has an inlet that is located above an effective intake of the pump. Well fluid must turn to flow down to the pump, with gas separating by gravity flowing upward while the liquid flows downward. The downhole assembly has various configurations to assure that fluid flows past the motor for cooling.

Abstract: A fast-acting rotor-locking mechanism for a vane-type camshaft phaser. A straight-sided locking pin is disposed in a bushing in the rotor and is urged into a sprocket well by a return spring. A pad disposed at the bottom of the well is a travel stop for the pin. When the pin is fully seated against the pad, the pad covers a portion of the end of the pin. The uncovered portion of the pin end, exposed to oil pressure for unlocking the pin when it is fully seated, is decreased over the prior art pin, permitting use of a lighter locking spring having a lower spring rate. Because of the lighter locking spring, the pin accelerates more rapidly and unlocks significantly faster than in a comparable prior art phaser.

Abstract: A system that includes a logger to record mechanical data for a concrete mass and to transmit the mechanical data to a reader. The system includes sensors, a microprocessor and a first memory device embedded in the concrete mass for generating mechanical strength data for the concrete mass and storing that information in the first memory device. In one embodiment the mechanical data is encrypted to prevent third parties from downloading and reading the data. In another embodiment, the logger communicates with the reader through communication wires. In yet another embodiment, the logger transfers data files to the reader by radio frequency signals.
