20080271766Tool for Crushing Coke - A tool for crushing coke includes a casing which in the operational state is connected to a drill rod and on or in which is arranged at least one cutting nozzle and one drill nozzle for drilling coke and at least one valve for controlling a direction of flow of water flowing through the drill rod and the casing through the cutting nozzle and the drill nozzle.11-06-2008
20090165617Decoking Tool - In a tool for cutting up coke in containers, including a housing mounted on a drill stem in the operating condition, and wherein at least one cutting nozzle for cutting and a boring nozzle for boring coke by means of a water jet, and a switching apparatus for controlling the feeding of pressurized water flowing through the drill stem and the housing are arranged, wherein the switching apparatus for switching the tool includes a linearly moveable switching element, a driving apparatus and a control apparatus, which is rotatable about the longitudinal axis of the housing as a function of a change of the water pressure by the driving apparatus to switch a valve to distribute the water and to pass it on, wherein depending on each angular position of the control apparatus the flow path of the water to the boring nozzle or the flow path to the cutting nozzle is free or obstructed, the switching apparatus is arranged in the housing of the tool above the area in which a separation of the supply path of the water is provided in the housing into flow channels for the water to be fed to the boring nozzle and the cutting nozzle, and the switching apparatus, for rotating the control apparatus by the desired angle, includes a switching element arranged in the water flow path and moveable transverse to the longitudinal axis of the housing, wherein the switching element is coupled with a member for converting the linear movement of the switching element into a rotational movement of the control apparatus.07-02-2009

20100111625ARRANGEMENT FOR GUIDING A DRILL STEM OF A DECOKING TOOL - So-called decoking, in other words, the emptying of a container in which coke arising from the operation of a refinery is deposited and carried out using a decoking tool with a free mounting on the end of a drilling bar. The mounting is achieved using a sliding guide on a guide plate, coupled to the container. Distortions in the container and the guide plate therewith as a result of temperature variations during operation of the refinery which could lead to function disturbance of the drilling rod are avoided, wherein the sliding guide and the guide plate are arranged with a spring relative deflection by at least one spring element in the manner of a spring damper.05-06-2010
20100275682Freefall arrestor - The invention relates to a safety device for a crosshead of a decoking plant arranged by means of a carrying device to be liftable and lowerable on profiles of a frame above a drum adapted to receive material, such as coke, and guided on guide rails of the profiles by means of rolls, and carried by a cable of a winch slung around return pulleys at the top of the frame and around a carrying pulley rotatably supported at the top end of the crosshead; and equipped with brakes for stopping the crosshead in an emergency, when the carrying device fails, and for intercepting the crosshead and fixing it on the guide rails or on the profiles. For a safety device, a test apparatus is provided for testing the brakes on site, comprising a carrying device, such as a brace, attachable on the frame, on which the crosshead is mountable for simulating a free fall of the same by means of a release device, and an arrestor device for the crosshead releasably attachable on the frame at a distance below the brace.11-04-2010
20100300720DRIVE DEVICE FOR A BORING BAR - A drive apparatus for a drill stem, in particular for de-coking systems, has a feeder (12-02-2010

20090255202Tile Flooring System - An acid-resistant tile floor system for biologically clean environments. A tensile-load-bearing grid is placed on a floor substrate. A mixture of an epoxy resin and a resin set-up agent is poured over the grid. Ceramic tiles are adhesively bonded to the epoxy resin mixture. The epoxy resin mixture forms an acid-resistant barrier on the floor substrate and an uninterrupted adhesive surface for the tiles. The grid is made of fiberglass or other suitable material. The openings in the grid allow the epoxy resin mixture to flow down to the floor substrate. The set-up agent in the mixture ensures that the epoxy resin sets up completely around the grid, To form the uninterrupted bonding surface for the tiles.10-15-2009

20100008714BALL AND SOCKET JOINT - A ball and socket joint for a motor vehicle is provided with a ball pivot (01-14-2010
20100054851BALL-AND-SOCKET JOINT WITH SEALING RING - A ball-and-socket or a bushing joint for a motor vehicle. The ball-and-socket joint has an essentially annular joint housing with an essentially cylindrical interior space in which a ball socket is arranged. The ball socket is fixed within the joint housing by a sealing ring and a ball, of a ball pin, is held within the ball socket. A surface of the sealing ring facing the ball socket has a radially outer portion that is smooth and a radially inner portion in contact with the ball socket that is serrated secures the ball socket from rotating within the joint housing. The ball-and-socket joint offers advantage with regard to the reduction in size, weight and manufacturing costs and the shorter tolerances in the area of the housing cover simplify production of the components and proportionally reduce manufacturing rejects.03-04-2010

20090034563Tunable diode laser system with external resonator - A tunable diode laser system with external resonator in Littrow or Littman configuration has an optical lattice on which the light beam from a laser diode is diffracted, a support element to hold the lattice or to hold a mirror, which reflects the light diffracted by the lattice, and an actuator to change the position of the lattice or the mirror. The tunable diode laser system enables a reliable mode-hop-free tuning and furthermore is easy and economical to realize by having the support element include a carrier, on which the lattice or the mirror is arranged, and a base body, while the actuator acts on the carrier and rests against the base body. The carrier is connected to the base body via linkages, such that a linear deflection of the actuator is transformed into a rotation of the carrier in the plane of the light beam, while the center of rotation lies outside the base body.02-05-2009
