Abstract: A headbox tube bank apparatus and method of directing flow through same is disclosed for permitting the flow therethrough of stock in a papermaking machine. The apparatus includes a tube bank frame for rigidly supporting the tube bank, the frame defining a plurality of openings. A plurality of tubes cooperate with the frame such that each tube extends through and is supported by an opening. Each tube has an upstream and a downstream portion, the upstream portion defining an internal cross-machine direction section of substantially circular configuration for maximizing the velocity of the stock through the tube.

Abstract: A clamp for preventing separation of a connected subclavian catheter and intravenous tubing has a tube-like member having internal ridges adjacent one end for gripping a resilient bulb portion of the tubing and has a series of radially moveable jaw members on the other end bendable inwardly to grasp the end of a needle head on the catheter. A lock ring positioned about the tube-like member is slideable into engagement with cam members on the jaw members to lock the latter position.
