Abstract: A T-fitting is formed from two precut lengths of tubing of the same, relatively small, inner and outer diameter. One length of tubing is formed with a reduced diameter neck section at one end whose outer diameter is approximately equal to its normal undeformed inner diameter. The second length of tubing is placed in a clamp which is advanced to successive work stations where a sidewall is punched and then drilled through to form a radial hole in one side of a diameter substantially equal to the inner diameter of the tubing. At a subsequent work station, the neck section of the first length of tubing is driven into a force fit into the drilled hole in second length of tubing. The assembled tubing is then removed from the clamp, brazed into a permanent T-tube assembly. The portion of the neck section which projects into the passage of the second length of tubing is then trimmed off by a drilling or reaming operation.

Abstract: Disclosed is a method of making pre-expanded braided sleeving from flexible strands of either conductive or nonconductive filaments, or a combination thereof, along with entrapped warp filaments of heat shrinkable material. The warp filament material is commonly known as heat reactive material and, when briefly subjected to heat below its fusion temperature, shrinks in the order of 30% to 50% of its length and very substantially expands the sleeving thereby greatly expediting the assembly thereof over an elongated object. Thereafter the sleeving is readily contracted into a snug fit with the object upon being tensioned between its opposite ends.

Abstract: An apparatus (60) is disclosed for accurately aligning and terminating conductors (4) of a flat multiconductor cable (2) to terminals (26) of a connector (18). This apparatus (60) is particularly suited for use with cables (2 ) that have closely spaced conductors (4). To ensure proper termination, the apparatus (60) forces the individual conductors (4) into respective grooves (38) of the cover (22) of the connector (18). These grooves (38) are molded in the cover (22) and are therefore, more accurately positioned than the extruded conductors (4). With the conductors (4) maintained in their resepctive grooves (38), the termination process is completed. This ensures that a positive electrical connection is effected between the connector (18) and the cable (2), even when the cable (2) has a nominal spacing between adjacent conductors (4) of 0.025 inches or less.
