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 |
20100275682 | Freefall 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 |

20100008714 | BALL AND SOCKET JOINT - A ball and socket joint for a motor vehicle is provided with a ball pivot ( | 01-14-2010 |
20100054851 | BALL-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 |
20130071175 | BALL PIN AND BALL JOINT - A ball joint with a ball pin and a steel ball pin with a joint ball. The ball joint and ball pin are suitable for use when, for example, solid-on-solid friction predominates under high static pre-loading or high operational loads and with small joint movements. A portion of the surface of the ball pin has surface layer hardening in order to increase a fatigue strength of the ball pin. The ball pin and the ball joint, on portion of the ball pin without the any surface layer hardened, includes a nitrided layer as wear protection. The ball pin and the ball joint provide an advantageous combination of high fatigue strength, good corrosion protection and high wear-resistance. The nitrided layer of ball joints, previously only regarded as improving corrosion protection, also functions as a wear protection. Thus, these ball pins overcome the mutual exclusion between surface layer hardening and nitriding. | 03-21-2013 |

20140168370 | DEVICE FOR OPTICALLY SCANNING AND MEASURING AN ENVIRONMENT - A method for optically scanning and measuring an environment by means of a hand-held scanner for producing 3D-scans is provided. The method including providing a hand-held scanner having at least one projector and at least one camera. At least one pattern is projected onto an object in the environment with the at least one projector. At least one camera images of the object which has the pattern projected thereon is recorded with a plurality of frames. Three-dimensional coordinates of points on the surface of the object are determined from each frame in the plurality of frames. A ring closure is determined in the plurality of frames. The determination comprising the steps of forming a frustum for each frame, comparing a last frustum of the last frame with a plurality of frusta to form an intersection, and selecting a frustum having the largest intersection. | 06-19-2014 |
