Patent number: 7320263Abstract: The invention relates to a controller and a method for controlling a maneuverable control object and comprising a control lever (1) designed to be manually maneuvered by an operator into various positions and a console (2) in which the control lever is pivotable about at least two intersecting pivot axes and in which the console is provided with a corresponding number of clamps (3, 4) swivel-mounted about their respective swivel axis (5, 6), which clamps are provided with slots (15, 16) through which the control lever (1) extends and along which the control lever can be led. Each clamp (3, 4) cooperates with its respective detention device (27, 28, 31, 32) for locking the associated clamp (3, 4) in at least one predefined detention position and hence limiting the movement of the control lever.Type: GrantFiled: October 3, 2003Date of Patent: January 22, 2008Assignee: Parker Hannifin ABInventor: Hans Gustafsson

Patent number: 7320264Abstract: An industrial robot manipulator including a first arm comprising a front arm part and a rear arm part. The front arm part is journalled in the rear arm part such that the front arm part is rotatable about a first axis relative to the rear arm part. Cabling extends along the front arm part and the rear arm part. A supporting device is operative to support the cabling. The supporting device includes a supporting arm arranged in the vicinity of the rear arm part and rotatably supported about a second axis and an auxiliary arm operatively connected to the front arm part. The supporting arm applies a spring pulling force on the cabling in a longitudinal direction of the cabling.Type: GrantFiled: July 11, 2001Date of Patent: January 22, 2008Assignee: ABB ABInventors: Torbjorn Albertsson, Thomas Carlstrom

Patent number: 7320265Abstract: A system for controlling an axial movement of an article is presented. The system comprises a support stage assembly and a spring suspension arrangement mounted on the support stage assembly. The spring suspension arrangement comprises first and second assemblies arranged in a coaxial relationship one inside the other. The first assembly is attached to the support stage assembly. The second assembly serves for supporting an article-carrying member and is driven for movement along the axis with respect to the first assembly. The outer one of the first and second assemblies is configured to define two spaced-apart parallel planes perpendicular to said axis. The first and second assemblies are attached to each other by first and second membrane-like members arranged in a spaced-apart parallel relationship along said axis.Type: GrantFiled: August 25, 2003Date of Patent: January 22, 2008Assignee: Nova Measuring Instruments Ltd.Inventors: Eran Dvir, Beniamin Shulman

Patent number: 7320266Abstract: Shock dampener incorporated into a hammer handle. Using a counter weight attached with a hinge pin to provide extreme shock dampening when striking solid objects with a hammer tool. Shock travels in waves known as vibration. When striking an object with the hammer's head, a shock wave is created and travels down the handle. The shock wave travels through the whole hammer handle at one time in an instant. This allows for energy of the shock to transfer into the counterbalance dampener hinge pin and vibrate the dampening member that is buffered with a form of rubber diffusing 95% of the shock energy with the dampening member.Type: GrantFiled: November 2, 2006Date of Patent: January 22, 2008Inventor: Kristopher Joseph Mueller

Patent number: 7320267Abstract: A ratchet box end wrench includes a shank, a ratchet, a ring gear, three wheel members, a belt and a crank. The shank includes a space defined therein, a first pivot hole defined therein and a second pivot hole in communication with the first pivot hole. The ratchet includes a ratchet portion disposed in the space and an axial portion extended from the ratchet portion. The ring gear is connected to the axial portion of the ratchet. The first wheel member includes a pivot disposed in the first pivot hole. The belt is engaged with both of the ratchet and the first wheel member. The second wheel member is connected to the first wheel member so that the first and second wheel members are rotational together. The crank is operatively connected to the second wheel member. The third wheel member is operatively connected to the first wheel member.Type: GrantFiled: December 26, 2006Date of Patent: January 22, 2008Inventor: Yu-Tang Chen

Patent number: 7320268Abstract: An apparatus for cutting and/or profile machining an edge of a pipe is provided. The apparatus includes a housing, a rotatable faceplate mounted on a front surface of the housing, and a tool holder mounted on the faceplate and holding a cutting tool. In a first embodiment, a cutting apparatus includes gearing that permits the tool holder to be moved relative to a surface of a pipe in a rapid-feed mode, a slow-feed mode and a rapid-return mode. In second and third embodiments, a profile machining apparatus includes a carriage having a profiling roller or shaft that advances (or retracts) relative to a pipe along a path defined by a template. The carriage to which the cutting tool is mounted is pivoted about a support shaft permitting the carriage and tool to change its angle and orientation relative to the pipe while advancing or retracting.Type: GrantFiled: April 22, 2004Date of Patent: January 22, 2008Assignee: Kenichi MoriInventor: Shinji Kawashima

Patent number: 7320269Abstract: A material cutting and feed roller has a peripheral roller surface that conveys the material to be cut, and a cutting device within the roller that cuts the material. The cutting device has a blade that, when cutting the material, passes through a closeable opening located inside the peripheral surface of the roller. The closeable opening through which the blade passes during the cutting process is closed when the cutting process is not occurring.Type: GrantFiled: December 19, 2001Date of Patent: January 22, 2008Assignee: Windmoeller & Hoelscher KGInventor: Fritz Achelpohl
