Abstract: A system for deposition of evaporated material on a substrate is provided. The substrate has a central axis. The system includes an evaporation vacuum chamber, at least one nozzle assembly, and a shadow mask. The nozzle assembly has a three-point plurality of point evaporation sources disposed adjacent to the central axis of the substrate and at a distance from the substrate whereby the nozzle assembly provides for molecules of evaporated material to arrive at the substrate at an incident angle of less than or equal to 5 degrees.

Abstract: Disclosed herein is a method for acquiring a dental object of a patient with an object volume, in particular at least a part of a skull, an upper jaw and/or a lower jaw. To do so, a plurality of segment volume ranges are defined in the object volume, where the segment volume ranges overlap at most partially and directions of the segment volume ranges are not parallel to one another. The image data of the segment volume ranges is recorded by an MRI machine within a measuring volume of the MRI machine A two-dimensional composite image is generated from the image data of the individual segment volume ranges by projecting the image data onto a target plane. The target plane is disposed parallel to a defined midsagittal 10 plane of the skull or corresponds to the midsagittal plane, where a first segment volume range at least partially includes the midsagittal plane of the skull.

Abstract: Disclosed herein is a method for capturing a dental object with an object volume, in particular, at least one part of a maxilla and/or a mandible, with the sue of an MRT apparatus. A plurality of MRT segment images, which depict the defined segmented volume regions are acquired by an MRT apparatus within a measurement volume of the MRT apparatus. The segmented volume regions overlap no more than partially. In this case a target surface is defined or has already been defined. Then a two dimensional composite image, which corresponds to a two dimensional aggregate image through the target surface within the object volume of the dental object, is generated computer-aided from the individual MRT segment images.

Abstract: A catwalk apparatus for forming stands from individual tubulars comprises a frame having a top surface adapted to receive tubulars. The apparatus also includes a skate mechanism capable of pushing and pulling the tubulars once loaded on the apparatus. The apparatus is adapted to receive at least two tubulars in a coaxial arrangement. The apparatus includes a rotating means for oppositely rotating the tubulars along their longitudinal axes. The skate mechanism is used to advance the tubulars together during rotation so as to allow cooperatively threaded ends of the tubulars to engage thereby forming a stand. The skate mechanism is also used to urge the stand towards the drill rig for subsequent hoisting and orienting vertically. A method and system for forming tubulars is also provided.
