The present invention pertains to a cable comprising: —at least one conductor coated by an insulation coating layer, —a first protective layer surrounding said insulation coating layer, said first protective layer at least comprising, but preferably being made of a tetrafluoroethylene (TFE) copolymer comprising from 0.8% to 2.5% by weight of recurring units derived from at least one perfluorinated alkyl vinyl ether having formula (I) here below: CF.sub.2═CF—O—R.sub.f, wherein R.sub.f is a linear or branched C.sub.3-C.sub.5 perfluorinated alkyl group or a linear or branched C.sub.3-C.sub.12 perfluorinated alkyl group comprising one or more ether oxygen atoms, said TFE copolymer having a melt flow index comprised between 1.0 and 6.0 g/10 min, as measured according to ASTM D1238 at 372° C. under a load of 5 Kg [polymer (F)]; —optionally, a second protective layer surrounding said first protective layer, and —an armor shell surrounding said first or second protective layer. The invention also pertains to use of the cable in downhole wells.

An electromechanical surgical system is disclosed including a hand-held surgical instrument, an end effector configured to perform at least one function, and a shaft assembly arranged for selectively interconnecting the end effector and the surgical instrument. The shaft assembly includes a linkage having a proximal housing and a distal housing at least partially received within the proximal housing. The distal housing is rotatable relative to the proximal housing and configured to selectively interconnect the end effector to the shaft assembly. The shaft assembly further includes a wire extending through the linkage having a central portion disposed within an annular groove defined between the proximal and distal housings. The central portion of the wire is annularly wound within the annular groove to define a coil. The coil is configured to at least one of radially expand and contract upon rotation of the distal housing relative to the proximal housing.

A cable assembly including a first connector, a second connector, and a cable is disclosed that routes power, and/or information between devices. The cable includes a first group of one or more conductors that are mechanically connected to the first connector and the second connector to route power and/or one or more wired information communications between the devices. The cable also includes a second group of one or more that is mechanically connected to the first connector to provide one or more wireless information communications between the first device and the second device or a third device which is not mechanically connected to the cable assembly.

A multi-member cable includes at least a first cable element and a second cable element. The first and second cable elements twist around a center axis of the cable in a counterclockwise direction multiple times to a first reversal point, then twist about the center axis of the cable in a clockwise direction multiple times until a second reversal point, with this pattern repeating along a length of the cable. Adhesion points are formed at intervals along a length of the cable to connect the first and second cable elements. The adhesion points may be spaced apart at an interval equal to a distance between the first and second reversal points. An outer surface of a jacket of the cable may include indications at the first and/or second reversal points, such as physical bumps or markings.

A durable coating which reduces ice adhesion and minimizes ice accumulation includes a polymeric binder and a film forming lubricant. The polymeric binder is selected from a fluoropolymer or silicone polymer having one or more reactive groups. The film forming lubricant is a lubricous fluoropolymer or silicone polymer. Methods of applying a durable coating are also disclosed.

A hybrid cable may include a central strength member and a plurality of buffer tubes helically wrapped around the central member. Each of the plurality of buffer tubes may house at least one optical fiber, and an outer jacket may surround the plurality of buffer tubes and the central strength member. Additionally, the central strength member may include one or more carbon nanotubes capable of transmitting a power signal.

A kit for joining opposing ends of two medium-voltage (between about 3.3 kV and about 52 kV) electrical power distribution cables, comprising an electrically-conductive connector for connecting the conductors of the cables, an electrically-insulating surround material for enveloping the connector, a partial discharge detector, comprising a generally cylindrical, electrically-conductive sheath around the insulating surround, from which an electrically-conductive element extends in an axial direction along the length of at least one of the cables, an outer protective tube for surrounding the remainder of the kit, wherein the conductive element is sufficiently long to project out of the protective tube. A partial discharge detector and a medium voltage cable run are also described.

A sensor assembly includes a connecting bar extending along a longitudinal axis and a tubular body extending along the longitudinal axis and at least partially surrounding the connecting bar such that the tubular body is radially spaced from the connecting bar. The tubular body includes a first skirt portion, a first plurality of cantilevered tabs extending from the first skirt portion in a first direction parallel to the longitudinal axis, a second skirt portion, and a second plurality of cantilevered tabs extending from the second skirt portion in a second direction opposite the first direction.

Induction heating extension cables including control conductors are disclosed. An example cable assembly includes: a first plurality of conductors in a Litz cable arrangement; an outer protective layer configured to protect the plurality of conductors from physical damage; and a second plurality of conductors that are electrically isolated from the first plurality of conductors and are protected by the outer protective layer from physical damage.
