Abstract: The invention relates to a method of performing oilfield operations for an oilfield, the oilfield having a subterranean formation. The method includes collecting a first volume data set of seismic data and a second volume data set of seismic data, co-rendering a visually-melded scene directly from the first volume data set and the second volume data set, displaying the visually-melded scene comprising a visualized geobody, where the visualized geobody corresponds to a portion of the first volume data set and the second volume data set, and selectively adjusting the oilfield operations based on the visualized geobody.

Abstract: The invention relates to a device for separating dust from flue gases from combustion plants, especially solid fuel combustion plants, comprising at least one dust filter via which the flue gases are guided, and by means of which the dust from the flue gases can be filtered out as it passes through the dust filter. In order to produce a device which separates dust in a highly efficient manner and which can be operated in a highly reliable manner and be used to heat combustion air for the combustion plant, the at least one dust filter is embodied as a bulk material filter in whose bulk material heat from the flue gases can be collected when the bulk material is cross-flown by the flue gases and by means of whose bulk material heat collected from the flue gases when the combustion air of the combustion plant flows through the bulk material filter can be given off to said combustion air.

Abstract: The invention relates to a process for coating web substrates (10), the substrate (10) being coated over at least part of its area with a first adhesive (12) and thereafter the substrate (10) coated with the first adhesive (12) being coated over at least part of its area with at least one second, further adhesive (14). Provision is made for the first adhesive (12) to be still wet or not yet cured when it is coated with the further adhesive (14).

Abstract: In order to improve a surgical positioning and holding device for positioning and holding a guide for a surgical machining tool, with at least one fastening element for fixation to a bone to be machined and with a platform held on the at least one fastening element so as to hold the guide, so that anchoring surfaces may be prepared in a simple manner and with a high degree of precision on a bone to be machined, it is proposed that the guide be mounted for rotation about a first axis of rotation and be designed such that at least one surface concentric with the first axis of rotation may be prepared with the machining tool guided in or held on the guide.

Abstract: In order to improve an implant for the replacement of at least a part of a natural articular surface of a bone forming part of a joint comprising an anchorage surface abutting against the remaining bone and an artificial articular surface directed away from the bone in such a way that as little bone substance as possible should be removed in a simple manner for insertion of the implant, it is proposed that the anchorage surface comprises at least one cylindrically shaped area, which defines a cylinder axis.

Abstract: Images being processed in a photographic laboratory system into different forms of output are automatically evaluated to determine for each image whether it is of sufficient quality to merit processing into a selected form of output. Each image is individually evaluated by determining a grade value for each of one or more characteristic properties of the image, by assigning a target value to each of the characteristic image properties relative to each available form of output, and by comparing the grade value to the target value for a selected form of output.

Abstract: Apparatus (10) for generating images includes a receiving device (1), a control device (7) and an output device (9). Image data, received by the receiving device (1), contains the image information of several images (B1 to B4; B5 to B9) of a common image production order. The image information, transferred to the output device (9), is output onto recording material. The sequence for transferring the respective image data of images (B1 to B4; B5 to B9) of the common order to the output device (9) is specified in accordance with at least one prescribed criterion set by the control device (7).

Abstract: In a saw for surgical purposes comprising a saw blade holder movable by a motor and a saw blade fixable in the saw blade holder, to enable insertion and removal of the saw blade without a tool, it is proposed that the saw blade holder comprise an insert guide for the saw blade with a holdback projection, that the saw blade carry a resilient detent projection which in a relaxed position, with the saw blade inserted in the insert guide, engages the holdback projection from behind, and that an actuating element be mounted on the saw blade holder for displacement against the resilient detent projection, the actuating element moving the resilient detent projection, during the insertion, into a tensioned position in which the detent projection is pushable past the holdback projection when the saw blade is pulled out of the saw blade guide.
