Abstract: DENTAL IMPLANT     ABSTRACT OF THE DISCLOSURE       A dental implant is disclosed for rigidly anchoring a prosthesis to a jawbone implant site. The first embodiment of the dental implant comprises a center post having a boss connected to the proximal end thereof. A plurality of fins extend radially outward along the center post along the entire longitudinal length thereof.           The boss includes a counterbore and a threaded hole for receiving a support cone having a threaded stud extending therefrom.     Alternatively the boss defines a socket for the reception of a correspondingly shaped plug disposed on the support cone. The base has disposed thereon a circumferential sleeve of ceramic material. The second embodiment of the dental implant comprises a major post having a plurality of elongated fins extending radially outward from both sides of the major post. The proximal end of the major post includes a similar counterbore and a threaded hole for receiving the stud of the support cone. One or more minor posts may be connected traversely through the elongated fins to add rigidity thereto. In each embodiment the support cone is configured to receive a prosthesis. The angle of the support cone with respect to the dental implant may be altered by angling the stud with respect to the support cone. A washer is provided for connection between the support cone and the boss or the proximal end of the major post for varying the rotational position of the tilted support cone with respect to the dental implant.

Abstract: ABSTRACT          LIQUID DEGASIFICATION DEVICE    A device for removing dissolved gases from liquids is provided by utilizing a tall column initially filled with liquid which is then opened at the bottom allowing the liquid level to drop forming a vacuum above the liquid level.  Dis-solved gases migrate to the vacuum area and the purified liquid is then drained from the bottom of the column and the process repeated.  The above method of providing a vacuum allows more efficient distillation due to the lower boiling temperature resulting from the vacuum over the liquid.

Abstract: ABSTRACT       The present invention relates to a disposable concrete forming apparatus.  The apparatus includes an elongate, tubu-lar and rigid form having at least one inner wall surface defining an enclosure in which concrete can be poured and allowed to harden.  The apparatus further includes a flexible liner of predetermined thickness which lines the inner sur-face to preclude formation of form lines on the hardened con-crete that correspond to markings on the inner wall surface of the rigid form.  The flexible liner has at least one out-side wall surface for each inner wall surface and is movable between a compressed position permitting  insertion of the liner into the enclosure and a normal expanded position with the outside wall surface pressing against the inner wall sur-face of the rigid form.  As a result, no gap is present be-tween the inner wall surface and the outer wall surface.

Abstract: Abstract Crochet tools for producing bands on a crochet galloon machine.   For the production of thin bands on ten or more crochet needles (10, 10') per centimetre of width, the stems of the crochet needles (10,10') are clamped over more than half the length of the nee-dle.     A knocking-over bar (20) fastened to the ma-chine has a free straight edge (66) which adjoins closely but without play those parts of the crochet needles (10,l0') which project out of the clamp device.   The crochet needles are clamped with adequate security against lateral bending.   There is no friction between the crochet needles at the knocking-over bar (20).          The crochet needles can be clamped in groups, so that they stiffen one another.   For the feeding of elastic threads use is made of combs (6) which are displaced laterally to-and-fro relative to the crochet needles in the working rhythm, but which are disposed at a uni-form height relative to the crochet needles.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention relates to a well clean out tool comprising an elongated body having first and second ends and being adapted to be received within a well borehole. The elon-gated body is comprised of a plurality of subs including a first sub at a lower portion of the body having a one way valve for permitting only upward flow of fluid. A second sub is arranged above the first sub for receiving and retaining fluid and debris passing through the first sub while a third sub is arranged above the second sub. The third sub includes a second valve for permitting flow only upwardly through the third sub. A fourth or pumping sub is arranged above the third sub with the fourth sub including an outlet for returning fluid to the borehole. The pump sub includes an elongated hollow piston recipricatingly driven within a casing of the fourth sub. During the upstroke of the piston, fluid and debris pass upwardly through the first second and third subs while during downward movement of the piston fluid is prevented from flowing downwardly by the valves and flows upwardly through a valve in the hollow piston toward the outlet of the tool.
