Abstract: A small, simple, accurate, low-cost wire cutting and stripping apparatus includes a wire feed mechanism which periodically feeds a measured length of an insulated wire strand to a wire cutter/stripper mechanism which clamps the wire strand, severs it and scores the insulation, axially separates the wire segment cut from the wire strand and strips the scored insulation during such axial separation. The wire feed mechanism is driven intermittently by a continuously rotating electric motor through an electrically-operated wire feed clutch/brake, the clutch mechanism of which engages in response to an electric signal from a timer switch (start wire feed) and which disengages in response to an electric signal from an electric wire measuring encoder (measure and stop wire feed). The wire cutter/stripper mechanism includes a stationary pair of separable clamps, a movable pair of separable bladed cutter/stripper heads and a movable pair of separable clamps.

Abstract: A control system for power tongs comprises two tongs torque limiters, one of which limits tongs torque to a very low (hand-tight) level; the other limits torque at full makeup to, for example, 2000 ft. lb. The hand-tight torque limiter is manually or automatically disabled after the hand-tight level is reached. The system enables the operator to verify that the threads are properly engaged before applying full torque to the connection. The tongs have a very high reduction ratio, so that torque rises very slowly and can be more accurately controlled.

Abstract: The tool comprises a frame with a roller rotatably mounted thereon. A molding contacting element is also positioned on the frame in such a way that when the base surface of a hard resilient molding engages said molding contacting element and the opposite surface of the molding engages the periphery of the roller, the molding is formed into a curve which decreases the width of the base portion of the molding. This decreases in width is just sufficient to permit the base of the curved portion of the molding to be inserted in a straight metal channel. When the molding is uncurved so it can lie straight in the metal channel, the width of the base of the molding increases enough to grip the sides of the channel to lock the molding in the channel.
