20150232761 | TOOL FOR CRUSHING COKE - The invention relates to a tool for crushing coke, and includes a housing | 08-20-2015 |
20140003747 | METHOD FOR MOUNTING A HYDRODYNAMIC SLIDING BEARING AND HYDRODYNAMIC SLIDING BEARING, IN PARTICULAR OF A MAGNETIC COUPLING PUMP | 01-02-2014 |
20140001004 | SPLIT CASE OF A MAGNETIC COUPLING, IN PARTICULAR OF A MAGNETIC COUPLING PUMP | 01-02-2014 |
20120138324 | TOOL FOR CRUSHING COKE - A tool for crushing coke using high-pressure water is attached to a drilling rod through which water flows at high pressure. The tool further a control device for directing the water into either drilling nozzles or cutting nozzles depending on the rotational position of the control device. A switching element driven by water pressure engages the control device to cause the control the device to rotate from one rotational position to another rotational position, thereby changing the tool from cutting to drilling or vice versa. | 06-07-2012 |
20110011648 | TOOL FOR CUTTING COKE AND OTHER HARD MATERIALS IN DRUMS - A tool used for cutting coke or other hard materials in drums, adapted for being mounted to a boring rod with which the water can be run under pressure into the tool thus that, the water can be run toward the boring and cutting nozzles, being provided with a valve mechanism that can rotate about a coupling angle for releasing and closing the flow channel ports depending on a control input, with a first coupling position of the valve mechanism for boring and another coupling position for cutting, whereby the valve mechanism can be coupled at a water pressure reduced to the coupling pressure by rotating about the coupling angle, is simplified as to construction and handling in that the valve mechanism comprises a valve body in the water intake area of the casing, which has a cylindrical shape and a section for the water flowing inside the casing, as well as being rotationally mounted and having the possibility to be lifted and lowered in a cylindrical section of the inner wall of the casing, the valve body being displaceable at working pressure to a lower position against a spring tension—depending on the preset control for the individual desired function of the tool—and on occurring the coupling pressure, under spring tension, to an upper position relative to a rotating motion of the valve body about the coupling angle. | 01-20-2011 |
20100300720 | DRIVE DEVICE FOR A BORING BAR - A drive apparatus for a drill stem, in particular for de-coking systems, has a feeder ( | 12-02-2010 |
20100111625 | ARRANGEMENT 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 |
20100014963 | CENTRIFUGAL PUMP - A centrifugal pump having a casing axially divided into two casing halves; an intake and a discharge; as well as an at least one-stage flow channel between the intake and the discharge for a medium to be pressurized; and a shaft mounted for rotation within the casing and being driven by motor; at least one impeller attached thereon and arranged in a stage channel of the flow channel; and at least one guide device on a partition wall arranged within the stage channel in the region of the intake of the associated impeller. There is provided, for influencing the pre-rotation within the flow in the intake of the stage channel of the impeller, that the radial angular position of the guide device arranged on the partition wall is adapted to be adjusted with reference to the plane of partition of the casing as zero position; a positioning device is mounted on the partition wall at a selectable angular distance from the guide device; and said positioning device is received by the casing in the region of the plane of partition of the latter. | 01-21-2010 |

| 07-02-2009 |
20090165617 | Decoking 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 |
20080271766 | Tool 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 |
