Abstract: A system includes a cable with a core material, an intermediate layer surrounding the core material, a retention assembly located around the core material and configured to compress the core material and restrict the core material from moving in the cable, and an outer metallic tubular surrounding the intermediate layer. Further an electrical device is coupleable to the cable.

Abstract: A sealing device comprising an expanding metal provides for ongoing self-healing capability for use as a seal in conjunction with any downhole device or tool in wellbore applications. The sealing device may be a ferrule, or other type of compression device, that may be used for connecting one device to another device, such as a tube to a fitting, or a communication line to a downhole device. Wellbore fluids activate the expanding metal causing a leak to heal itself.

Abstract: A system for control using a hydraulic fluid includes a hydraulic control line for flowing the hydraulic fluid, a fluid line in fluid communication with the hydraulic control line, a flow controller configured to regulate a flow of the hydraulic fluid in the fluid line, and a piezoelectric device in fluid communication with the hydraulic control line and configured to actuate the flow controller upon receiving a selected flow of the hydraulic fluid.

Abstract: A method of actuating a well tool includes the steps of: increasing pressure in a fluid line of a fluid metering device; closing a pilot-operated valve in response to the pressure increasing step; and discharging a predetermined volume of fluid from the metering device in response to the pressure increasing and valve closing steps. A fluid metering device for a well tool includes a piston separating chambers; and a pilot-operated valve which selectively prevents fluid communication between the chambers in response to at least a predetermined pressure being applied to a fluid line of the metering device, and which permits fluid communication through the valve between the chambers in response to pressure in the fluid line being less than the predetermined pressure. A greater pressure may be applied to the fluid line to thereby bypass the metering device and allow fluid to discharge from the line.

Abstract: Saccharide in mixtures are separated into groups or individual saccharides and tested for their affinity for particular proteins. The method of the invention is carried out by conjugating saccharides in a mixture with charge-generating moieties and moieties capable of fluorescing such as 4-amino-1-naphthalene sulfonic acid (ANSA) to form conjugates. The saccharide conjugates are subjected to electrophoretic resolution within gels. The resolved bands of material can be seen under ultraviolet light and are electro-blotted onto charged nylon membranes to provide a stable record of the electrophoretic separation. The blots (visible under ultraviolet light) on the nylon membranes are brought into contact with particular proteins in order to determine the binding affinity of these particular proteins to particular saccharides on the nylon membrane. The proteins are preferably bound to labels so that the binding of the proteins to the saccharides can be easily detected.
