Abstract: There is disclosed a communications cable having a cable jacket and a first pair of twisted wires disposed within the jacket, each wire thereof having a conductor surrounded by a first insulating material. A second twisted pair of wires is disposed within the jacket and has a twist lay length different from that of the first twisted pair. Each wire of the second twisted pair has a conductor surrounded by an insulating material. The insulating material of the first twisted pair differs in a physical property from the insulating material of the second twisted pair, the physical property of the insulating material of the second pair being correlated with the physical property of the insulating material of the first twisted pair and with differences in twist lay length of the first and second twisted pairs so that the phase delay of the twisted pairs is matched. There is also provided a communications cable having more than two twisted pairs.

Abstract: Exposed forward ends of conductors of the electric wire and the flat cable are connected to each other. The conductors of the electric wire set to a length adapted for being overlaid on the conductors of the flat cable are held in overlaid relation with the conductors of the flat cable between insulating partitioning walls formed on the upper surface of a holder for isolating each adjacent pair of the conductors of the electric wire. The overlaid portions of the conductors are thus connected in the above-mentioned overlaid relation, and are insert-molded including the connected portions, thereby connecting the electric wire and the flat cable directly.

Abstract: A cooling device mounting a fan unit (3) above a heat sink (2) mounted on a heat-generating element (1) or buried therein, which produces an effective air flow and achieves a uniform cooling action by having the heat sink (2) embodied in various shapes. Further, a cooling fan disposed away from the heat sink (2) or to the side of the same is used for effective cooling through an air conduit passage formed by pipes or a cover.

Abstract: A coaxial cable having coaxial inner and outer conductors which are separated by a helix of solid dielectric material. The helix extends through the annular space between the inner and outer conductors, and the helix is wound around the inner conductor. The inner edge of the helix engages the inner conductor and the outer edge of the helix engages the outer conductor. The outer edge of the helix forms multiple notches along the length of the helix, and the body of the helix is hollow.

Abstract: A flexible, gas tight electrical coupling for a gas cooled electrodynamic system such as an electrical generator includes a first connector element that is in communication with a first combined coolant and electrical path and has a first passage defined therein for a coolant, a second connector element that is in communication with a second combined coolant and electrical path and has a second passage defined therein for the coolant, a flexible tube for communicating the first passage in the first connector element with the second passage in the second connector element, and an electrical connection for electrically connecting the first connector element to the second connector element. According to one aspect of the invention, the electrical connection is external to the flexible tube, resulting in cost savings and other advantages when compared to an internal electrical connection.

Abstract: Electrical termination and connector structures for electrical cable, and a penetrator for electrical power and/or signals through a pressure barrier, provide, in different embodiments, mechanical attachment to the cable and to individual conductors of a multi-conductor cable; and provide fluid-tight seals to protect the terminated and interconnected conductors from adverse ambient gases and liquids. A molded elastomeric body, in one embodiment, provides the rugged fluid-tight seals. The electrical termination and connector structures withstand cycled pressure and temperature environments, and include a mechanism for restraining the extrusion or other displacement of cable insulation under conditions of cycled pressure and of temperature. The structures also accommodate axially adjustable installation and differential axial expansion and contraction.

Abstract: A flat cable has a plurality of parallelly disposed fine-conductive wires and insulating wires. The conductive wires are divided by the insulating wires into channels which are respectively connected to terminals of different devices. The channels may be arranged easily by changing the interposing position of the insulating wires. Since the conductive wires have a fixed resistance, desired resistance may be obtained by only increasing or decreasing the number of the conductive wires in a channel.

Abstract: An electric cable joint is enclosed within a heat shrinkable sleeve. The joint region is sealed against the ingress of moisture by a material made of a non-crystalline polymer whose glass transition temperature is less than -40.degree. C. Further, the material has a viscosity at 35.degree. C. of less than 10.sup.6 Pa-sec and a viscosity at 95.degree. C. of greater than 10.sup.3 Pa-sec (both viscosities measured at a shear rate of 0.02 sec.sup.-1) and a minimum tack value of about 140 gm/cm.sup.2.

Abstract: A wire connector including a first member and a second member defining a cavity therebetween, the first member including a first channel and a second channel, the second member including a third channel and a fourth channel, the first, second, third and fourth channels being in communication with to the cavity, forming a substantially X-shaped form, the X-shaped form including a substantially central point. The first and the third channels are substantially collinear. At least one of the first and the third channels having a first additional opening for accommodating a first wire. The second and the fourth channels are substantially collinear. At least one of the second and third channels having a second additional opening for accommodating a second wire. The winding of the wires is by rotating the first member relative to the second members substantially around the central point, thereby winding the first and the second wires of the wire pair.

Abstract: In a method for the production of connection carriers, a V-shaped recess (3) is formed in the connection carrier (1) by punching, then a very precise slit (18) is produced in the immediate vicinity of the recess end region (10) by stamping or caulking the carrier cheeks (13) and ( 14) of the connection carrier (1). At least two windings (26) and (27) of a wire (5) are then inserted into the slit (18), whereby the windings cannot slip onto each other because of the dimensions of the slit (18) which resulted from stamping. Finally, hot-forming of the connection carrier (1) occurs, so that the windings (26) and (27) are completely surrounded in the slit (18) and an electrically conductive connection between the connection carrier (1) and the wire (5) is produced.
