Abstract: Method and apparatus for reliable splices to be made in hard-rolled copper and alloy tapes without buckling or overlap and with splices that are stronger than the tape metal, itself. The invention permits an operator to load a second reel of tape in position such that when a first reel is exhausted, the system will automatically butt splice the tail end of the first tape to the front end of the second tape without the presence of the operator.

Abstract: Apparatus and method for butt-splicing hard-rolled and.backslash.or wide copper and copper alloy tapes employs a rolling electrode and varies the contact angle of the tape ends during soldering.

Abstract: Apparatus and method are described for the automatic feeding of solder or other bonding agent with tension applied to the solder supply so that it retracts from the point of fusion an instant before it is entirely liquified.

Abstract: To splice two metal tapes by means of a solder wire that is thicker than the tapes themselves, their terminal edges are positioned upon one electrode, a spacing shim is inserted upon one of the tapes, another electrode is lowered onto the shim, the wire is inserted into the channel formed by the tape and shim edges and the electrodes, the shim is withdrawn to lower the upper electrode down upon the solder, and the latter is then fused.

Abstract: Means and method are presented for butt-splicing two metal tapes by confining molten solder between two carbon electrodes while the tape edges are moved together.

Abstract: The invention relates to an improved reciprocating pump providing oil for low pressure, self-contained oil-filled cables. it is particularly important to have a gas tight system in such a pumping plant since the oil in the storage tank (6) has to be kept under vacuum at all times to keep the oil in a gas-free condition. The air or gas driven oil pump (8) has two piston rod seals (9,10). The area between the two seals is provided with an inlet (11) and outlet opening (12) through which oil can be flushed from the high pressure side of the pump (8) to the top of a storage tank (6).

Abstract: A splicing machine for carrier strip is automated to lower the pathway of terminal strip over the splicing jaws and to sense the engagement of the strip by the movement of a guide bar within the jaws that is being pulled forward by the strip.

Abstract: A guide bar for carrier strip grips the strip ribbon between adjustable pins and can accept a wide range of strip dimensions.

Abstract: An oil cable pumping plant including at least one oil tank and at least one air/gas driven piston type oil pump connected to the oil tank, at least one air/gas source connected to the air/gas inlet of the pump via a pressure control. An exit for the air/gas as well as an oil exit are connected to at least one oil filled cable, and an oil flow indicator. The pump in its normal operating condition provides a predetermined oil pressure at its outlet. An oil flow control is interconnected between the oil flow indicator and the air/gas pressure control for controlling the oil.

Abstract: A guide bar for carrier strip grips the strip ribbon between adjustable pins and can accept a wide range of strip dimensions. The pins project from spring-actuated disks that are recessed into the upper surface of a slide bar. Associated gears at the undersurface of the bar cause pairs of the disks to turn in unison.

Abstract: The guide plates of a soldering apparatus for carrier strip are provided with grooves and slide bars that fit the grooves. The bars have pins fitting holes in the strip and means for precisely positioning the bars lengthwise in the grooves.

Abstract: This invention relates to continuous manufacturing of insulated wire and conductor, and in particular to heating cables having "cold ends". A process is described by which predetermined lengths of resistance conductor (4) and of cold end conductor (9) are continuously and alternatively jointed together. After insulation and provision of additional protective sheats the continuous composite conductor is cut into cold end heating cables. A conductor jointing process is described.

Abstract: The present invention relates to a bending strain relief device with adjustable stiffness to be used in connection with cables or pipes. The stiffness of the device is made adjustable by having an expandable body arranged between the cable or pipe and a stiffening rod arrangement. When inflated, the expandable body causes increased friction between the stiffening rod layers and the relief may be locked in any desired position.

Abstract: A back-up system is provided for a pumping plant or a pressure reservoir system used to maintain insulating oil under pressure in high voltage submarine power cables which includes a gas driven membrane pump to insure a small outflow of oil at a rupture point in the power cable to prevent water from penetrating the cable. The proper operation of the membrane pump is insured by introducing degasified oil at the drive side of the pump during the stand-by and test modes of operation of the back-up system.

Abstract: A multiwire conductor in which a layer of wires surrounds a center wire. The center wire has a predesigned structure which produces many small, negligible kinks instead of few intolerable ones, which may otherwise occur as the result of temperature changes or stress variations.

Abstract: To prevent undue bending and resultant cracking of cables that span movable bodies, the cable is fastened at a plurality of points along a flexible structure connecting the bodies. A detector determines the relative movement of the bodies and provides information to a control system for positioning and directing at least two of the fastening points so that the cable will bend substantially evenly in spaces between adjacent fastening points as the bodies move.

Abstract: Metallic tape is butt spliced, i.e. without overlapping the tape, by measuring a fine strip of silver solder into a gap between the cut edges of the lengths of tape being spliced in such a manner that the strip of solder extends over one of the lengths and under the other. The area being spliced is pressed between carbon electrodes and the silver solder is fused by the passage of resistance current.

Abstract: Buoys for use in submarine cable and pipe laying are fastened to the cable or pipe by lengths of line stored within the buoys. The buoys descend with the cable to a point where they are unaffected by wave action. Water is free to enter the bottom of the buoys and compress the gas therein thus reducing buoyancy and, through the release of a brake, controlled, in turn, by a float, allowing the line from which the cable or pipe is suspended to pay out.
