Abstract: A sealing member for effecting a gas-tight closure about a cable at an inlet to a hollow cable sleeve fitting. The member is annular in form and is divided on a plane parallel to the cable axis for assembly about the cable after boring a selected passage for the cable through the member. The sealing member has a plurality of radially- and circumferentially-continuous, radially outwardly-extending, longitudinally-spaced ribs engageable via a coating of plastic potting compound with an inner surface of the inlet fitting. The ribs are held in spaced relation by an integral reinforcement member which is spaced radially inwardly of the outer circumference of the ribs. A center portion of the reinforcement member is apertured so that selective boring through of the member to form a cable passage will leave internal radial ribs for bearing against the cable via a second plastic potting compound. Any number and size of cable passages may be provided for.

Abstract: A submersible motor comprising a first housing including a motor and a second housing enclosing electrical connections between the motor and a jacketed electrical cord to the second housing. The first housing has a cavity therein in the periphery thereof. A body of compressible resilient elastomeric material is positioned in the cavity and has an exterior configuration and dimensions which conform generally with the configuration and dimensions of the cavity. The body has a plurality of generally axial passages therein through which the magnet wires from the motor extend. The wires have a diameter so that they can be readily inserted through the passages in the body. The second housing has an annular wall extending axially through the open end of the cavity in the first housing and operable, when the second housing is in mounted position on the first housing, to compress the body radially into tight conformity with the wires from the motor.

Abstract: A prewired electrical switch having an attached electrical cable includes a housing which provides a cable seal which prevents fluid from traveling by capillary action from outside the housing through the electrical cable into the interior of the switch housing where the fluid can interfere with the normal operation of the switch. The cable seal is provided by a separate cable receiving section of the housing which has pockets which receive and isolate uninsulated portions of the individual electrical conductors of the cable. A non-conductive potting compound such as an epoxy resin fills the pockets and forms fluid-tight seals with the uninsulated portions of the individual conductors and adjacent insulated portions within the pocket. The potting compound also forms a fluid-tight seal with the end of the cable.

Abstract: An anode connector for use in an impressed current cathodic protection system comprising a cup-shaped housing member made from a material which is permanent under anodic conditions with a plug insert member with a central aperture made from conventional current carrying metals which is press fit into the cup-shaped housing. The cup-shaped housing can then be welded to an anode. A cable conductor for the anode which is well insulated except for the end is positioned with the uninsulated end in the central aperture of the plug insert and soldered thereto to provide excellent electrical conductivity between the cable and the plug. The cup is then filled with suitable insulating potting material which covers the plug and the cable conductor to a height above where the insulation begins. This invention provides a rigid, reliable anode connector which is able to withstand anodic conditions in an impressed current cathodic protection system while still providing the current to the anode.

Abstract: A cylindrical high temperature logging tool assembly supended from the shield of a coaxial cable for insertion into the interior of a well bore. To isolate the instruments contained within the interior of the cylindrical assembly from the fluids or steam within the well bore, and to facilitate assembly, the cylindrical oil tool comprises a plurality of axially aligned segments including a grease holding cavity at the end thereof wherein a quantity of non-conducting grease is packed and is compressed therein by the threadable engagement of the sections. Since most greases are generally incompressible, the threaded assembly provides a technique by which the grease pressure level within the housing can be achieved which are greater than the pressure head within the well bore. In this manner an integral structure is provided which can be deployed at various depths within the well bore and which furthermore provides selective arrangement of sections to arrange the requisite instrumentation for well bore logging.

Abstract: A splice case is disclosed providing sealed protection for splices such as in telephone cable situated in adverse environmental conditions. The case includes a shell defining a cavity for enclosure of a splice. The shell is longitudinally split and includes openings at the ends thereof along the longitudinal split for receiving incoming cable. Thermally responsive sealant extends along the longitudinal split and a heating element is provided for causing the sealant to effectively seal the enclosed splice. A multiple cable adapter of thermally responsive sealant is sized to fit within a cable opening in the splice case and includes a plurality of longitudinally extending channels for accommodation of multiple incoming cables. Sheets of material exhibiting high thermal conductivity extend from the adapter such that the heat of the heating elements may be conveyed to the body of the adapter.

Abstract: A housing for splicing a trunk cable to a plurality of tip cables has a detachable end cap for receiving the tip cables. The detachable end cap is constructed from a pair of attached molded sections having flat spaced parallel surfaces between which is positioned a rubber sealing member. A plurality of holes extend through the two sections and the sealing member for receiving the tip cables. The first section includes a plurality of integrally molded conically shaped knock-out members positioned in the holes of the first section and projecting through aligned holes in the sealing member and the second section. The knock-out members form a plug that substantially fills the associated holes of the sealing member. The knock-out members are removed from selected holes at the time of installation for receiving the tip cables into the housing.

Abstract: A terminal connector for high-current electrical cables includes an electrically-insulating casing of resin-impregnated glass fibers surrounding an end portion of an electrical cable, and a conductive member connected to the end portion of the cable and extending through an axial end of the casing. The casing has an inner collar which cooperates with two movable nuts to adjustably mount the conductive member in an axial end of the casing, and an outer collar to secure the casing to a base plate. The conductive member is formed with an annular groove which receives a resilient sealing ring. The sealing ring slides along an inner circumferential wall of the casing and seals the interior of the casing from its exterior throughout the entire adjustment range of the conductive member. A protective electrode attenuates electrical fields in this axial end, and an electrically-insulating housing having a fluid medium contained in its interior surrounds the casing.

Abstract: A protective sleeve for a cable which is to be pressurized internally for leak-detection and cable preservation has a seal near an end thereof through which one or more cables pass into the interior of the sleeve. The seal has a lip formed about the periphery of its inner face, subject to pressure within the sleeve and extending radially and longitudinally from the face to engage the interior surface of the sleeve or sealing compound placed thereon. Pressure within the sleeve forces the lip against the interior surface of the sleeve to form a gas-tight seal regardless of reasonable variations in the internal diameter of the sleeve. One or more lamellations back up the inner, sealing face of the seal and engage each cable passing through the seal. The seal is conveniently made in two pieces for fitting about a continuous cable, and the sections of the seal are joined by tongue and groove arrangements or enlarged sealing surfaces at the joints.
