  • Patent number: 11885216
    Abstract: A method for completing a subterranean formation includes conveying a perforator assembly into a borehole drilled in the subterranean formation. The perforator assembly includes at least one shaped charge and at least one tracer package that includes at least one fluid production tracer material and a tracer injector. The method further includes forming at least one tunnel in a production structure by detonating one or more shaped charges and injecting the at least one fluid production tracer material into the formation using the tracer injector after the detonation of the at least one shaped charge. The at least one production tracer material physically associates with at least one resident fluid in the subterranean formation.

  • Patent number: 7537406
    Abstract: A drive screw having an axial bore is disposed within a tubular container. A cap for closing the container has mounted therefrom an applicator that is insertable in the bore of the drive screw. A first seal and a second seal, on the drive screw, form with the inner wall of the container and the outer wall of the drive screw an annular compartment for housing a cosmetic composition. A normally closed channel is provided between the compartment and the bore of the drive screw. A drive on the cap and a complementary drive on the drive screw cooperate with the first seal and the second seal to decrease the volume of the compartment in which the composition is housed each time the container is opened by removing the cap. A valve opens the channel in response to the decrease in volume in the compartment when the cap is removed so as to permit composition to flow through the channel into the bore of the drive screw to contact the applicator.

  • Publication number: 20070169776
    Abstract: A pressure support system that comprises a patient circuit, a docking assembly, and a tank. The patient circuit delivers a pressurized flow of breathable gas to a patient. The docking assembly has an inlet and an outlet that is adapted to receive the pressurized flow of breathable gas, and is also adapted to be connected with the patient circuit. The tank is constructed and arranged to be removably connected with the docking assembly, and enables the pressurized flow of breathable gas to pass therethrough. The tank is also adapted to contain a liquid such that a humidity level of the pressurized flow of breathable gas is elevated as the pressurized flow of breathable gas passes therethrough.

  • Publication number: 20070145673
    Abstract: A backing plate support system is provided for a mailpiece feeder mechanism wherein mailpieces are conveyed vertically, on-edge along a transport deck to a transfer station for subsequent sortation and delivery. The backing plate support system includes a guide track disposed along and adjacent to the transport deck and a plurality of backing plates each having a guide support fitting at its base. The guide support fitting engages the guide track and supports the backing plate in an orthogonal position relative to the transport deck. The backing plate support system, furthermore, includes an advancing belt disposed adjacent the guide track and adapted to be driven linearly along the transport deck and a mechanism for coupling each backing plate to the advancing belt. The mechanism facilitates relative movement of the backing support plate relative to the advancing belt in one direction while inhibiting relative motion thereof in an opposing direction.

  • Publication number: 20060282290
    Abstract: A fluid delivery device including a housing, a reservoir positioned within the housing, and a transcutaneous access tool positioned within the housing and including, a cannula in fluid communication with the reservoir and linearly moveable along an axis of the transcutaneous access tool through a port in a wall of the housing, a deployment member secured to the cannula and movable along the axis of the transcutaneous access tool against the wall of the housing defining the port, and an annular seal coaxially positioned about the cannula and positioned between the deployment member and the wall of the housing defining the port, so that the seal provides a substantially fluid-tight seal between the deployment member and the wall of the housing when the deployment member is moved against the wall of the housing.
