Patent number: 5860774Abstract: A device for resurfacing the valve face of a poppet valve in which the pressure between a cutting surface and the valve face is controllable by the operator during the surfacing operation. A bearing case is rotatably attached to a base which is attached to a pair of gripping blocks. A cutting head is rotatably mounted on the bearing case. The cutting head, the bearing case, the base and the gripping blocks define a passage into which a valve stem is inserted. The gripping blocks are clamped in a vise which in turn clamps the valve stem in the device. When the bearing case is rotated, pressure between the cutting surface and the valve face is increased. When the cutting head is rotated, the valve face is resurfaced.Type: GrantFiled: December 22, 1997Date of Patent: January 19, 1999Assignee: Neway Manufacturing, Inc.Inventor: Boris R. Teper

Patent number: 5427478Abstract: An apparatus for positioning a bowling ball during a drilling process and method that provides reproducible orientations of the ball for accurately modifying and repeating the drilling process is described. The apparatus affixed a bowling ball while exposing a sufficient portion of a surface of the ball where middle finger, ring finger and thumb holes are to be drilled. The apparatus positions the bowling ball for drilling holes of varying pitch without requiring the ball to be removed from its rigidly affixed position within the apparatus. Holes having severe pitches are easily drilled and reproduced, including oval holes having preselected oval rotations. A computer program converts inputted hand measurements to digitized apparatus movements for positioning the ball prior to drilling a desired hole. Digital encoders indicate apparatus movement that is matched with computer output for ease and repeatability in drilling a ball.Type: GrantFiled: September 30, 1993Date of Patent: June 27, 1995Assignee: John N.

Patent number: 4896663Abstract: A hand-held drill jig is utilized to locate and maintain a central axis through a head and an associated neck of a femur enabling a blind hole to be drilled into the femoral head oriented to the central axis. The drill jig is adjustable to accommodate a broad range of sizes of femurs and can be readily attached to, then removed from, the femur. A positioning mechanism is provided to firmly engage both the outer peripheral surface of the femoral head and the femoral neck. This operation renders associated drill bushing immobile relative to the femur and orients its longitudinal axis with the central axis. A drill bit is then capable of being guided through the drill bushing and into cutting engagement with the femoral head.Type: GrantFiled: October 14, 1988Date of Patent: January 30, 1990Assignee: Boehringer Mannheim CorporationInventor: Mark V.

Patent number: 4642002Abstract: A holder for supporting motor driven tools against the reaction torque which occurs during operation. Two supports which are spaced from one another are provided for the tool. The supports are rigidly connected with a clamping device. Since only one support is effective at any given time for a given direction of rotation of the tool, the direction of rotation of the latter can be changed without having to modify the holder. The holder, together with the clamping device, is fastened directly onto the workpiece.Type: GrantFiled: December 9, 1983Date of Patent: February 10, 1987Assignee: REMS-WERK Christian Foll und Sohne GmbH & Co.Inventor: Rudolf Wagner

Patent number: 4599924Abstract: A process and device for producing a bearing eye or a transverse perforation in the clevis of the actuating rod of a brake power booster. The assembled brake power booster is inserted in a locking frame of the device, the clevis being retained at a cutting tool provided in a locking frame at a desired design distance of the clevis from the fixation flange of the booster casing. Upon insertion of the booster in the locking frame, the legs of the clevis are punched by a cutting punch so that in a single process step, a transverse punch hole or perforation to receive the pivot pin of the brake pedal is made maintaining a close tolerance to the desired design distance, i.e. independently of the specific position of mounting of the actuating rod and independent of the distance between the end of the clevis and the fixation flange of the booster casing.Type: GrantFiled: June 20, 1984Date of Patent: July 15, 1986Assignee: ITT Industries, Inc.Inventors: Gerd Klostermann, Nabil Henein
