Abstract: A plastic handle about two inches long has a longitudinal slot sized to receive a rubber band. After the rubber band is inserted into the slot, a locking pin is inserted into the first end of the rubber-band loop which has been inserted in the slot. The rubber band is then pulled back through the slot, thereby locking the plastic handle, rubber band, and locking pin into a bundle tie assembly. The second end of the rubber band is wrapped around an extension cord, rope, or the like and snapped around the plastic handle of the first end of the rubber band. The bundle tie assembly self-tightens to quickly and neatly secure the extension cord.
Abstract: A pallet holds one or more circuit boards for processing. A pallet opening for receiving the circuit board has grooves at one side to retain an edge of the circuit board and rotary clips at the other side to receive and hold the opposite edge of the board. Each clip is a disk which is mounted for rotation about a central axis and is constrained to two angular positions by a detent. A notch in the disk receives the circuit board when in one position and clamps the board against a seat when in the other position. The notch is deep enough to allow the board to be shifted laterally for alignment with test apparatus.
Abstract: A holder for flexible sheet material providing a substantially horizontally oriented housing containing convergent parallel walls forming an interior passageway with an opening. Contained within the housings' passageway are several spaced cylindrical rods with removable handles attached and exposed through the opening of the housing. The relationship between the diameter of the rods and the opening between the convergent walls is such that the rods can not pass through the opening and exit the housing. Sheet material moved into the opening in an upward direction between the inside front of the housing and the rods is secured by pulling on the handles attached to the rods to activate the wedging action. The sheet material can be removed from the holder by moving the handles vertically within the passageway to allow the sheet material to slip freely out of the housing.

Abstract: An improved flow control device for regulating the flow of fluid through flexible tubing wherein the flow control device utilizes a rotatable member with trunnions positioned to be captively guided and rotated along guide surfaces. The rotatable member is easily inserted into the clamp body yet once it is placed therein it is difficult to remove without excessive force. The clamp body affords a rigid structure with the opposing walls being fixed at their ends yet are flexible enough to afford entry of the rotatable member into the clamp body for placement of the trunnions in the guide surfaces. In one embodiment, a ramp means is provided through an infeed section wherein the ridge portions forming the ramp merge with the guide surfaces so that when the trunnions of the roller move up the ramp and onto the guide surfaces, an outward flexing of the clamp wall is effected with a retention of the trunnions on the guide surfaces.
