A sealing unit capable of sealing engagement with an end of a tube. The tube has an outer wall and a bore surrounded by an inner wall. The seal unit comprises a tapered element having a longitudinal axis. The tapered element is adapted for insertion into the bore in the end of the tube. A sealing ring co-axial with said longitudinal axis of the tapered element to provide an annular channel between the tapered element and the sealing ring. The annular channel has an open end and a closed end. The annular channel is capable of receiving the end of the tube through the open end of the annular channel. A base, co-axial with the longitudinal axis of said tapered element, contacts the sealing ring to hold the sealing ring in place and contacts the tapered element to terminate the annular channel at the closed end. When the sealing unit is in sealing engagement with the end of the tube, the tapered element sealably engages the inner wall of the tube and the sealing ring sealably engages the outer wall of the tube.

The target apparatus of claim 1 wherein each of the target latching means are a detent element affixed to a free outer end of the spanning lever, which element is disposed to engage and retain an arrested depending arm in the target depressed mode until the resetting target plate is activated. 3. The target apparatus of claim 1 wherein the resetting target plate is provided with a fixed bead on its depending lower end, which bead serves to deflect the associated spanning lever a somewhat greater distance than are the deflections of the other spanning levers, with such transient gap acting to release all of the other target latching means from the depressed mode. 4. The target apparatus of claim 1 wherein the first set of torsional biasing means mounted along the first shaft are each a helical spring that biases its associated depending lever arm in a first arcuate direction that maintains the target in an upright mode until projectile impact rotates same to the depressed mode. 5. The target apparatus of claim 1 wherein the second set of torsional bias means mounted along the second shaft are each a helical spring that biases its associated spanning lever in an arcuate direction counter onto the rotational bias imposed by the first torsional bias means maintaining the free end of the spanning lever in an upward direction. 6. The target apparatus of claim 1 wherein the deflection resisting force of each target may be varied for projectile momentum by adjusting the torsional tension being provided by the first plurality of torsional means upon the upright mode of the associated target plate. 7. The target apparatus of claim 1 wherein an arrest element is provided along the upper perimeter of the second shaft proximal to each spanning lever and which element functions to limit the rotation of each spanning lever, while being subject to the second set of torsional biasing means. 8. The target apparatus of claim 1 wherein the bias of the first plurality is counterclockwise while the bias of the second set of torsional bias means is an arcuate direction counter to that of the first set of torsional biasing means. 9. The target apparatus of claim 1 wherein the first plurality of torsional biasing means are provided with means to vary the rotational bias being imposed upon each of the targets to accommodate the variable momentum of impacting projectiles. 10. A target apparatus including a generally horizontal rigid frame for operatively supporting a linear array of targets, each of which are independently adapted for rotation between a useful upright mode, and in inactive depressed mode, with each target also being adapted for release from inactive mode and biased rotation back to the upright orientation comprising: (a) an elongate rigid first shaft disposed between the longitudinal ends of the rigid frame and adapted to permit independent mounting of targets thereon; (b) a plurality of plate-like targets arrayed, spaced apart, along the first rigid shaft, with each being deflectable rearwardly upon a projectile impact, with each target further comprising: (i) a first collar-like element provided at the one lower end of a target which is adapted to permit arcuate rotation of the target itself thereabout; and, (ii) a depending arm provided on the first collar-like element which rotates in tandem with the induced arcuate movement of the target itself; (c) a target rotation biasing mechanism secured along first shaft and adapted to hold the linear array of targets in the upright mode; (d) an elongate rigid second shaft, spaced apart from t he first shaft, also disposed between the longitudinal ends of frame, being adapted to support a plurality of latching means, with each of such latching means comprising: (i) a second collar-like element which is rotatably mounted on the second shaft being located opposing one of the targets; and (ii) a spanning lever tied at one end to its respective second collar-like element and bridging the lateral gap between the first and second shafts so as to effect for latchable, but interruptible, contact with the opposing depending arm of the target; (e) a latch mechanism for holding said target array in a depressed mode to obstruct rotation of the target back to the upright mode; (f) a single target plate adapted to serve as both a deflectable target and as a target array reset means for any of the other targets while latched in the depressed mode, said target plate also being provided with a depending arm, having a somewhat greater length than the depending arm of the other targets, so as to make transient contact with the spanning lever of an opposing latching means, such that upon missile deflection of the single target plate, and rotation of its associated depending arm, such arm rotates both the opposing spanning lever and its associated second collar-like element to deflect downwardly, along with the other spanning levers, interrupting the latched position of the depending arms, so that all the targets rotate from their depressed mode back to the upright mode, and to the target array orientation for renewed usage. nged in parallel, laterally spaced relationship. 13. A liquid flow distributor as set forth in claim 1, wherein said receptacle comprises a generally U-shaped channel element having a generally flat base member and a pair of generally parallel, laterally spaced flanges located on opposite side edges of the base member. 14. A liquid flow distributor as set forth in claim 13, wherein said base member has a hole therethrough that is in alignment with a corresponding hole in a sidewall when the receptacle is mounted in an operational position. 15. A liquid flow distributor as set forth in claim 14, wherein said flanges extend vertically when the receptacle is mounted in said operational position. 16. A liquid flow distributor as set forth in claim 15, wherein said attachment element comprises a generally planar, generally rectangular plate having a lateral dimension that coincides essentially with the distance between said flanges, said plate and said channel being configured such that said plate is held against said base member by said flanges. 17. A liquid flow distributor as set forth in claim 16, wherein said receptacle includes a stop in said base member which contacts a lower edge of said plate to hold the plate in a proper operating position. 18. A process column comprising a packed bed and a liquid flow distributor as set forth in claim 1 for distributing liquid across a top face of said bed. 19. A method for operating a process column comprising providing a packed bed in said column and distributing a descending flow of liquid ac
