Abstract: A method of and apparatus for detecting ends of successive fly strips connected end to end by a slide fastener chain. The successive fly strips, with their first flaps overlapping a tape of one fastener stringer and with their second flaps overlapping the other fastener stringer, are fed lengthwise along a straight path. Then, the second flaps are folded over the respective first flaps as the fly strips pass through a folder extending through a fixed point on the straight path. During this folding, a trailing end of the preceding second flap is temporarily deflected so as to provide a relatively large triangular space between confronting ends of an adjacent pair of the second flaps when the same confronting ends arrive at the fixed point. Finally, a detector senses the presence of the triangular space, which indicates the arrival of confronting ends of an adjacent pair of the fly strips.

Abstract: A retrievable float valve hanger tool assembly provides a hanger sub having a first upper connection for attaching the hanger sub, for example, threadably, to a drill string or work string. A second lower connection means on the sub provides both external and internal threaded (for example) connections, which allow the sub to be connected on its inner threads to a float valve canister and at its external threads to an extension which forms a protective housing about the float valve and its valve canister during operation. The device places the float valve below the joint of the sub and the extension so that an explosive charge can be detonated at the joint allowing easy removal of the float valve from the drill string in the event that the drill pipe becomes stuck. A continuous bore through the assembly allows fluid circulation through the tool in the work string and also allows the explosive charge to be lowered by wireline, for example, to the tool assembly at the appropriate joint.
