The invention relates to a unitary cable terminating press for terminating flat cable of the type having multiple individual conductors extending therethrough. This is especially applicable for terminating such cable which is arranged in a twisted configuration defining a cable of substantially round configuration. The press includes a guide and clamp having a plurality of individually operable clamp members for first positioning and clamping a first predetermined portion of the cable in a manner such that the conductors within that portion are clamped in a desired position. Thereafter, additional portions can be selectively clamped by the individual clamp member in a predetermined sequence. A cutting blade then serves to cut the cable at a location relative to the clamp. A flat cable connector can then be positioned in open engagement and a press mechanism is brought down on the connector to terminate the cable with the connector.

Press for use in aligning and terminating flat cable

Several embodiments of reduced crosstalk ribbon cable having alternating twisted and straight sections of indefinite length are disclosed, crosstalk being reduced by differing starting positions of alternate twisted pairs, differing lay of alternate twisted pairs, and variation in lay along the length of alternate twisted pairs. A preferred embodiment uses offset starting positions, and a lay in alternate twisted pairs substantially longer than that of adjacent pairs, becoming shorter to minimize the nontwisted portion resulting from the time to bring adjacent pairs into planar alignment. An apparatus for making such cable is also disclosed, having several wire supply twisters and several second twisters, removing the twist inserted by the wire supply twisters while forming twisted pair ribbon cable sections, allowing indefinitely long twisted sections. Twisters are provided in two groups operating in opposite directions, preventing curl of the cable. The paired conductors are maintained in precisely laterally spaced relationship by heat bonding to thermoplastic film.

This invention relates to a specific type of multi-conductor cable comprising a plurality of insulated wire conductor pairs, each of said insulated conductor pairs having alternating twist and straight portions and having alignment means for precisely aligning both the twisted portions and straight portions of said insulated conductor pairs in a predetermined, laterally spaced, relationship with respect to each other. The alignment means of the multi-conductor calbe of this invention comprises a laminated plastic sheet, initially formed from first and second plastic sheets or films, the laminated film having

A stove or furnace in which the products of combustion are recirculated inside the combustion chamber by means of a V-shaped partition or baffle, the apex of which extends downward directly above the primary fire zone, so that the combustion products rising from the fire are deflected outward and then flow downward back into the primary fire zone. Secondary air may be mixed with the unburned combustion products above the primary fire zone to form a combustible mixture which is burned on re-entering the fire zone.
