Publication number: 20110062204Abstract: A tool for breaking a shaft has a first and a second tubular element, both provided with inner through bores adapted to receive a first and second portion of a shaft in a first position of the tool. A first handle is fixedly connected with the first tubular element and the second tubular element is connected to a second handle. A bottom surface of the second tubular element is in contact with a neck surface of the first tubular element forming a shearing plane perpendicular to the main axis of the tool. A rotation between the two tubular elements around this axis creates a twisting movement of the two shaft portions received within the two tubular elements, and shears the shaft portions at the shearing plane. The second handle turns the first tubular element around an axis and has a gear engaging the second tubular element for transmitting the rotation of the second handle into a rotation of the second tubular element for producing the twisting movement.Type: ApplicationFiled: August 31, 2010Publication date: March 17, 2011Applicant: STRYKER TRAUMA SAInventors: This Aebi, Robert Dominik

Patent number: 6619332Abstract: A snap tie breaker tool includes a handle connected to a body shaft with a locking brace and two receiving tubes attached to the body shaft. The snap tie breaker tool operates by sliding a concrete snap tie through both receiving tubes. The portion of the concrete snap tie that passes through both receiving tubes is then bent to a position perpendicular to its original position. Next, the handle is rotated so that the bent portion of the concrete snap tie contacts the body shaft. Once contact is made, an increased amount of force is applied to continue rotating the handle and the concrete snap tie. Eventually, the concrete snap tie will break and can be removed from the concrete wall. The process of breaking the concrete snap tie with the snap tie breaker tool is substantially less time consuming and takes less work than conventional methods.Type: GrantFiled: May 22, 2001Date of Patent: September 16, 2003Inventor: Paul Edward Prunty

Patent number: 5395025Abstract: A method and apparatus for imparting an angle cleave to a plurality of optical fibers. The cleaving device comprises a base having a support surface, the support surface having two lower pads which are aligned with two upper pads on a hinged cover, so that the fibers may be clamped between the respective pairs of lower and upper pads. One of the upper pads is designed to shift with respect to its corresponding lower pad; when a fiber is clamped between these pads and the upper pad moves, the fibers twist as a result of the induced torsional load. When the fibers are scored and cleaved while in the twisted state, the resulting end faces are at an oblique angle with respect to the fiber axes, which is beneficial since this reduces signal reflections at the fiber-to-fiber interfaces.Type: GrantFiled: March 29, 1993Date of Patent: March 7, 1995Assignee: Minnesota Mining and Manufacturing CompanyInventors: Victor J. Borer, John W. Durham

Patent number: 5368211Abstract: An apparatus cuts one or several optical fibers obliquely. The cutting edge (6) creates the beginning of a break on the fiber that has first been subjected to a torsion and to a tension. The fiber is immobilized upstream of the cutting point. Then, the fiber is tightened downstream from the cutting point. Next, a tension is exerted on the part of the fiber or fibers located between the application of the tightening (3,4). The tightening also involves an exertion of a torsion force upon the optical fiber.Type: GrantFiled: April 2, 1993Date of Patent: November 29, 1994Assignee: France TelecomInventors: Boitel Michel, Jean-Marc Cailleaux, Mahe Thierry

Patent number: 4836006Abstract: A method and apparatus for continuously forming pointed terminals from a length of wire. The length of wire is moved to a position where a portion of the wire is positioned between a pair of opposed swedges. The pair of swedges is closed to engage and deform the portion of wire. The wire is then moved to position the deformed portion of wire at a wire severing location and another portion of the wire is positioned between the pair of opposed swedges. The wire is twisted relative to the deformed portion to separate the portion of the wire ahead of the deformed portion to form a terminal. The pair of swedges are closed simultaneously with the twisting to deform the next portion of wire and these steps are repeated.Type: GrantFiled: December 30, 1987Date of Patent: June 6, 1989Inventor: Maurice H.

Patent number: 4748733Abstract: The guide tube is mounted on a fixture with the split-pins of each old split-pin assembly straddling a knife edge. The nut of each old split-pin assembly is engaged by a socket of a wrench and a high torque is impressed on the nut. The torque is of sufficient magnitude to shear the weld by which the nut is joined to the split-pin and/or to shear the pin particularly at the edge of a keyway where a button to which the weld is joined is engaged. The knife edge which each split-pin straddles prevents the pin from turning under the torque applied to the nut. After the weld or the pin is sheared the nut or the nut and the pin fragment joined to it is unthreaded from the pin or pin fragment and the separated parts are disposed of. Typically the nut of an old split-pin assembly has diametrically cut slots in its wall. The socket of the wrench is provided with projections which engage the nut in the slots. The torque is applied to the nut through these projections.Type: GrantFiled: August 29, 1986Date of Patent: June 7, 1988Assignee: Westinghouse Electric Corp.Inventors: Joseph J. Hahn, David A. Howell

Patent number: 4038746Abstract: Opening device for a package of coins. For the opening of packages of coins, there is provided a keylike device having a handle portion and two prongs at one end thereof spaced from each other and projecting from such end in generally parallel relationship to each other. One of said prongs is straight-sided and adapted for lying against the outside of a coin package when the device is in use. The other of said prongs is relatively shorter, is spaced from the first prong a distance slightly greater than the thickness of the rim of the packages with which said device is to be used and has a portion projecting from the end thereof in the direction remote from said first prong. In use, said device is placed with said first prong outside of the package and the second prong adjacent the inside of the rim of said package and the key is twisted to bring said projection against or under the free edge of said rim. Said key is then rocked to lift said rim and simultaneously further twisted to tear said package open.Type: GrantFiled: December 24, 1975Date of Patent: August 2, 1977Inventor: Meryl L. Bromley
