    Abstract: Pre-twisted multiple wires having N twisted sections per full-twist pitch, where N is a predetermined constant integer, are juxtaposed to a roller which carries plural conformal seat means in a circumferential manner. The arcuate spacing between adjacent seat means is correlated with 1/Nth of the full-twist pitch of the particular twisted wires. Associated with the roller is ratchet means which allows the roller to be indexable in increments correlated with a full-twist pitch of the particular multiple twisted wires. As a result, the twisted wires are fed out in full-twist linear increments and, hence, with the same orientation of the wires for each incrementing step. Moreover, by judiciously seating one of the N possible adjacent twist sections of the twisted wires with respect to the seat means, the twisted wires can be fed out selectively with N possible orientations. The preferred embodiments described herein orient a pair of twisted wires which have two twisted sections per full-twist pitch, that is to say, two half-twist sections per full-twist.

    Abstract: The pinner apparatus affixes multiple pins (P) in the holes (H) of a ceramic substrate (5) by simultaneously impacting the pins with a piston assembly (11) which temporarily places the pins in a viscoelastic fluid state. This leaves each pin with an extension that interlocks with the ceramic substrate. … The piston assembly is driven by a pneumatic high pressure system (48) which is adjustable to the number of pins being simultaneously impacted. Release of the piston assembly is delayed until the air pressure becomes stabilized prior to impact. A vacuum system (68) returns the piston to its originating position after impact whereupon the piston assembly is ready for the next impact cycle. A shuttle valve assembly (33) selectively connects the high pressure or the vacuum system to the chamber (21) in which the piston assembly is movable.
