Abstract: ABSTRACT OF THE DISCLOSURE Refractory tubings, either in amorphous, polycrystal-line or single crystal form, are made by moving a preformed tub-ing of a refractory material and heating zone relative to each other, the heating zone providing sufficient heat to melt through the tubing and form a molten ring which is continuously advanced through the tubing.  The heating zone is provided by focusing a plurality of laser beams in a manner to adjust the energy distri-bution of each beam to essentially equalize the absorption of the laser energy around the entire surface of the tubing.  The tubings may be formed as single crystals by using appropriate seeds; and by controlling the rate of movement of the tubing sections on either side of the molten ring the wall thickness and diameter of the final tubing may be adjusted.

Abstract: ABSTRACT OF THE DISCLOSURE                  DROPWEIGHT SAMPLE TESTER            This invention provides a process and apparatus for determining the energy absorbed by a test-piece of material during its fracture.  The test-piece is supported horizontally between two separated anvils, and a dropweight is released from a position above the test-piece so that the same can be struck and fractured.  Means are provided for determining, by measuring a determining characteristic of the motion of the dropweight after the test-piece has been fractured, the theoretical height from which the dropweight would have had to be released in order to have that post-fracture motion if the test-piece had not been in the way.  The difference between this calculated theoretical height and the actual height of release, multiplied by the weight of the dropweight, provides a measure of the energy absorbed by the test-piece during its fracture.

Abstract: AN ELECTROMAGNETIC FLUID OPERATING APPARATUS ABSTRACT OF THE DISCLOSURE          In an electromagnetic fluid operating apparatus such as an air compressor in which a piston with an armature axially reciprocates along a path substantially at a right angle to the magnetic flux generated by a stator core due to alternate operation by electromagnetic attraction and mechanical repulsion, exact collimations are automatically established between the armature and the stator core and between the piston and a cylinder for the piston when they are assembled together, thereby minimizing biased frictional abrasion of coacting sliding surfaces.  Provision of an internal air reservoir at the air outlet terminal effectively reduces pulsation of air supplied by the apparatus.
