Abstract: A tape can comprise a strip of dielectric material, with adhering patches of electrical conductive material. The patches can be substantially electrically isolated from one another. The strip can be disposed in a communication cable to provide a shield that is electrically discontinuous or has high resistance between opposite cable ends. Each patch can interact with electromagnetic radiation associated with electrical signals transmitting over the cable. The patches can collectively interact with the transmitting electrical signals in a cumulative or resonant manner to produce a spike in return loss at a particular frequency of the transmitting signals. The frequency location of the spike can depend upon the sizes of the patches, with size impacting manufacturability. The patches can be sized such that the spike falls within an operating frequency of the transmitting signal but is suppressed, so the cable meets return loss specifications while offering manufacturing advantage.

Abstract: Generally, aspects of embodiments of the invention include cable separator spline which comprises a plurality of longitudinally extending walls joined along a central axis of the spline, and a plurality of longitudinally extending channels. Each longitudinally extending channel is defined by a pair of the longitudinally extending walls, where the pair of longitudinally extending walls includes a first wall substantially thicker than a second wall. Other embodiments include a cable separator spline assembly having a plurality of longitudinally extending walls joined along a central axis of the spline, and a plurality of longitudinally extending channels. Each longitudinally extending channel is defined by a pair of the longitudinally extending walls, wherein a pair of opposing longitudinally extending walls have defined through them a common gap defining two separate sub-splines having T-shaped cross-sections.

Abstract: A process as claimed for the invention for internal high-pressure reshaping of a hollow section (12) in a reshaping tool, a fluid being introduced under high pressure P1 into a hollow section and this section having a transitional area with different wall thicknesses in the area of an edge (18 to 21) to be blocked, is characterized in that the shape selected for the hollow section (12) in the initial state is such that a thickened area (22 to 25) extends a certain distance from the edge (18 to 21) into the wall section (14, 16) with smaller wall thickness. As a result, constrictions can be avoided during reshaping and favorable edge geometries can be achieved (FIG. 2).

Abstract: A connecting element for insertion into the ends of at least two hollow sections of different cross-section, in particular in the case of a middle node for an instrument panel transverse beam in automobile manufacture is such that a push-fit body is shape-formed—by way of extrusion of a light weight alloy, plastic or other extrudable material—on a frame with side walls extending in the direction of insertion, the push-fit body is of smaller cross-section than the frame and contains lengths of the frame walls. That frame preferably surrounds the push-fit body which in turn forms a corner of the frame. In addition, the frame may exhibit an integral frame bracket outside one frame side wall whereby the frame bracket walls are aligned with parallel frame walls.

Abstract: A device for forming a hollow profile formed as a multi-chamber profile by an internal high pressure generated by a fluid pressure medium within the hollow profile containing a sealing die engaging in the profile chamber with a carrier part and a collar arranged on the carrier part sealing the face side of the profile chamber. The die also has a passage opening as a pressure medium supply and/or extraction channel. The collar is a resilient rubber die part arranged on the face of the carrier part facing the profile chamber and on the free face of the collar is provided a preload plate which is anchored by way of the fixing member penetrating the collar in the carrier part lying on the collar so that the collar is squeeze-clamped between the preload plate and the carrier part.

Abstract: A data communication cable includes a cable jacket surrounding a plurality of twisted pairs of insulated conductors disposed longitudinally over the length of the communication cable and arranged side-by-side to reduce cross-talk between the twisted pairs. The cable also includes a first region having a first thickness disposed between two regions having a second thickness. These regions, or another structure located on the outer surface of the jacket, are arranged to prevent symmetric stacking of several communication cables and thus reduce alien cross-talk arising from outside of the communication cable.

In addition, the frame (30) may exhibit an integral frame bracket outside one frame side wall whereby the frame bracket walls are aligned with parallel frame walls.

Abstract: A cross web core in a high performance data cable maintains geometric stability between plural twisted pair transmission media and between each twisted pair and the cable jacket. The cross web core may further isolate twisted pairs from each other by including conductive or magnetically permeable materials. By so doing, loss, impedance and crosstalk performance are improved.

Abstract: A cable testing device apparatus has been developed so as to measure the NEXT and ELFEXT characteristics of a cable containing a plurality of twisted pairs. In particular, the present invention simultaneously provides each twisted pair within the cable with an electrical signal of equal magnitude and measuring the equivalent power sum output for each of the individual twisted pairs within the cable. Thus, a total of 25 measurements for each test are needed, for a total of 50 tests.

Abstract: A vehicle frame for powered vehicles with load-bearing sections and on these at least one housing for the upper end of a shock absorber; the housing is made of an extruded alloy, features a cover which is dished upwards, and is made up of a plurality of extruded shaped parts, each of which features shell-shaped sections which are curved in cross-section; projecting from the shell-shaped sections are at least two flange strips which serve as means for attachment to the neighbouring shaped part. The shaped part comprises shell-shaped sections each of which in cross-section is part of a circle and at the ends feature--as viewed in cross-section--flange strips running approximately radial to the central axis (B) of the housing.

Abstract: Method of making a twisted conductor wire unit in which each wire of the pair is individually insulated. The twisted pair is provided with an outer extruded polymeric layer while a vacuum is applied to the pair at the extrusion position. The vacuum draws the polymeric layer down onto the pair and forces the insulated wires together along the length of the unit. The vacuum is insufficient to produce substantial longitudinal indentations in the polymer layer. This avoids spaces being provided between the insulated wires in the finished structure and provides a substantially constant distance between the wires to improve electrical and cross-talk characteristics.

Abstract: High frequency cable with short twist lays with the insulation thickness of conductors being different from that of others, the thickness of insulation being dependent upon twist lay length so as to achieve a desired characteristic impedance and signal attenuation.

Abstract: An electrical cable having a jacket surrounding a metal shield which, in turn, surrounds the cable core. The jacket comprises a polyolefin with a modifier provided by a carboxylic acid or anhydride thereof with the jacket lying in intimate overall contact with an outer surface of the shield and being bonded by the modifier throughout the overall contact areas to the shield.

Abstract: A cable for use as aerial service wire having a core of conductors and a load carrier in the form of a plurality of spaced apart tensile reinforcing members spaced from the core as a group laterally on one side of the core. Part of the jacket surrounds the core and is interconnected to another jacket part surrounding the group of filaments. The jacket part surrounding the filament group has a width greater than its thickness so that it may fit within a wedge clamp for stringing purposes. The two parts of the jacket are capable of being separated between the filament group and the core to allow a wedge clamp to be fitted. For this purpose, the cable may be fitted with a non-adherent tape inside the jacket and between the jacket parts with the jacket parts interconnecting around edges of the tape.
