A cable coater system for a downhole tool includes a cable coater. The cable coater may include a housing and one or more rollers that are coupled to the housing, wherein the one or more rollers are configured to rest on the downhole cable while guiding the cable through openings in the cable coater during wireline operations. The cable coater may remain on cable during all spooling (on and off) activities for the duration of operations and activated to coat the cable upon the final pull out of hole and prior to storage of the cable. The spooling in and out of the cable may further be automatically controlled by providing a positional indicator of the cable coater and thus where the cable is in three-dimensional space relative the spool.

A wire waterproof structure including a water-stopping material, wherein: the water-stopping material is configured to seal at least a partial region of a conductor comprising an assembly of a plurality of strands, the water-stopping material contains a resin material, and a filler dispersed in the resin material, and the filler has an average particle size of 1 ?m or more and 15% or less of an outer diameter of the strands, and a content in the water-stopping material of 1 mass % or more and 20 mass % or less, relative to the resin material.

A dispenser apparatus for a curable liquid material is disclosed. The apparatus comprises a flexible bag defining a first compartment for accommodating a first component of a curable liquid material, and a second compartment for accommodating a second component of the curable liquid material and adapted to communicate with the first chamber to enable mixing of the first and second components to initiate curing of the curable liquid material. A first clamp temporarily prevents mixing of the first and second components, and an elongate nozzle communicates with the second compartment to dispense the mixed curable liquid material therefrom. A second clamp temporarily prevents passage of the curable liquid material from the second compartment to the nozzle.

Provided are apparatuses for the infusion of one or more additives into the surface of a linear substrate. The apparatuses include a processing barrel having an infusion chamber defined therein as well as a linear substrate inlet and a linear substrate outlet. The processing barrel also includes an infusion fluid inlet and an infusion solution outlet in fluid communication with the infusion chamber. The infusion chamber is dimensionally reconfigurable, optionally during an infusion process.

An apparatus and method for modifying an aspect of an exterior polymer material or polymer type material of a linear substrate with a fluid. The apparatus include a variable exposure gap within which the linear substrate is exposed to the fluid. The width of the exposure gap is varied with the speed of the linear substrate traversing the exposure gap to maintain a constant exposure time of the linear substrate with the modifying fluid.
