Patent number: 11234799Abstract: A method for manufacturing a dental implant apparatus that comprises an implant and an implant support that can be placed next to one another by contact surfaces and that have contours providing security against rotation that are integrally molded on in one piece. The implant and an implant support have mutually matching contours that prevent a rotation of the implant and the implant support when placed next to one another. A tool system for carrying out the described methods and a dental implant apparatus that is manufactured in a corresponding manner are further disclosed. A contact surface of the implant is ground using a first grinding gauge that has a grinding surface having the shape of the contact surface of the implant attachment but not having the shape of the contour providing security against rotation of the implant.Type: GrantFiled: October 26, 2016Date of Patent: February 1, 2022Assignee: CERA M GMBHInventors: Stefan Ries, Walter Lutz

Patent number: 5123237Abstract: A blade guide for supporting a reciprocating sickle blade in an agricultural mower. The blade guide includes a unitary, integrally formed structure formed of a resilient, molded thermoplastic material. To avoid wear, metallic wear plates are provided where the reciprocating sickle blade contacts the blade guide. The side edges of the wear plates cooperate with the reciprocating sickle blades to provide a cutting action as the sickle blades reciprocate. In one embodiment, the side edges of the wear plate are beveled to improve the cutting action. Preferably, the wear plates are molded in place during manufacture.Type: GrantFiled: February 15, 1991Date of Patent: June 23, 1992Assignee: Lavelle Industries, Inc.Inventor: Walter Lutz

Patent number: 4971547Abstract: A system for distributing wax or a similar substance in semi-solid form is provided which includes a liquid wax supply system, a wax conditioning system including a heat exchanger which cools the wax to a semi-solid state and an accumulator for storing conditioned wax until needed, and a die press or similar work station which receives semi-solid wax from the accumulator in a continuous stream or flow. Such a system allows a lost wax die press to operate without need to manually open and reload the press with wax. An automated control system according to the invention allows die press reloading to occur automatically when needed, and operates the wax conditioning system as needed to maintain a supply of wax in the accumulator. Wax tunneling problems are avoided by means of a piston disposed in the heat exchanger which is movably interposed between hot liquid wax entering the heat exchanger and cooler, semi-solid wax leaving the heat exchanger.Type: GrantFiled: May 25, 1988Date of Patent: November 20, 1990Assignee: Signicast CorporationInventors: John A.
