An unlimited stroke drive method for pumping fluid from an oil well in which the well has a tubing string extending from the earth's surface down to a fluid producing formation. The method includes the steps of positioning a pump barrel within the tubing, an upper end of the pump barrel having communication through a standing valve with the interior of the tubing string, vertically reciprocating a length of flexible cable within the tubing string to vertically reciprocate a plunger within the pump barrel to allow a lower portion to quickly fill with fluid from the producing formation and then to a downward position in which fluid within the pump barrel lower portion is transferred through a traveling valve to an area within the pump barrel above the plunger to move formation fluid from within the pump barrel to the interior of the tubing and thence to the earth's surface.

An apparatus for rapidly filling a hydrogen tank with a hydrogen gas comprises a hydrogen source; a hydrogen tank; a passage which connects the hydrogen source and said hydrogen tank; and a mechanism for varying the hydrogen-filling rate. The mechanism for varying the hydrogen-filling rate changes the hydrogen-filling rate depending upon the pressure within said hydrogen tank. The apparatus can suppress heat generation at the initial filling stage where the temperature is easily increased. Also, even if it takes longer time for increasing the pressure within the hydrogen tank at the initial filling state, the delayed time can be caught up and, the apparatus and the process of the present invention can totally attain a rapidly filling with hydrogen.

A method has been developed to exploit the desirable material and process characteristics provided by a low powered laser material deposition system, while overcoming the low material deposition rate imposed by the same process. One application of particular importance for this invention is direct fabrication of functional, solid objects from a CAD solid model This method of fabrication uses a software interpreter to electronically slice the CAD model into thin horizontal layers that are subsequently used to drive the deposition apparatus. The apparatus uses a single laser beam to outline the features of the solid object and then uses a series of equally spaced laser beams to quickly fill in the featureless regions. Using the lower powered laser provides the ability to create a part that is very accurate, with material properties that meet or exceed that of a conventionally processed and annealed specimen of similar composition. At the same time, using the multiple laser beams to fill in the featureless areas allows the fabrication process time to be significantly reduced.

An improved filling valve specially configured for attachment onto a conventional, high speed liquid filling machine that is typically utilized in food product container packaging lines to quickly fill large numbers of containers, such as bottle or cans. A filler valve has several improvements that result in greater reliability in operation, increased operational speed, and easier adjustment in operational parameters. The filler valve including a manifold that receives a manifold insert and a spring nut that abuts to a slider. The slider is the only moving part of the filler valve. A filler stem is received through the slider and attaches to the manifold. For filling, the top opening of a bottle is placed against a spanner nut and the manifold lowered, thereby compressing the slider into the manifold to insert the stem into the container. A liquid is then injected into the container, while displaced air is exhausted into the co-axial annular space between the stem and the slider. The stem also preferably contains four outlet ports.
