Abstract: Traditional orthodontic treatment often involves the use of basic repositioning devices, such as braces, and the use of supplementary devices, components or accessories to achieve desired end results. Such components may be mounted on fixed, non-removable devices or they may be part of a removable appliance typically worn prior to the application of the fixed devices. As with traditional treatment, it may be desired to utilize similar components when repositioning teeth with removable elastic repositioning appliances. Due to the nature of elastic appliances, such components may take a variety of forms ranging from readily available traditional accessories to specially created devices. Thus, traditional components may be mounted on or embedded in an elastic appliance, or the appliance may be formed to provide similar components. Likewise, the appliance may be modified to provide additional features for specific orthodontic treatments.

Abstract: Synthesis gas is produced from a carbonaceous fuel, using a process in a gasification reactor. The carbonaceous fuel and an oxygen containing stream are supplied to a burner of a gasification reactor, wherein a CO2-containing transport gas is used to transport the solid carbonaceous fuel to the burner. The weight ratio of CO2 to the carbonaceous fuel is less than 0.5 on a dry basis. The carbonaceous fuel is partially oxidized in the gasification reactor, whereby a gaseous stream of synthesis gas is obtained. This synthesis gas can be further processed in a downstream process path to convert it into a hydrocarbon product. The downstream process path may contain a methanol-synthesis reactor to produce the hydrocarbon product in the form of methanol. The downstream process path may contain a Fischer-Tropsch synthesis reactor to produce one or more from a range of hydrocarbon products.

Abstract: A method and system for producing synthesis gas comprising CO, CO2, and H2 from a carbonaceous stream using an oxygen containing stream. A stream containing a carbonaceous material, and a stream containing oxygen are injected into a gasification reactor, where the carbonaceous stream is partially oxidised to obtain a raw synthesis gas. The raw synthesis gas is removed from the gasification reactor and directed into a quenching section wherein a liquid, preferably water, is injected in the form of a mist.

Abstract: Improved CMP uniformity is achieved by providing improved control of the slurry distribution. Improved slurry distribution is achieved by, for example, the use of a slurry dispenser that dispenses slurry from a plurality of dispensing points. Providing a squeeze bar between the slurry dispenser and wafer to redistribute the slurry also improves the slurry distribution.

Abstract: A process for measuring the alignment of different layers on a semiconductor wafer (33) includes forming repetitive alignment marks (14, 24) having substantially the same period on the different layers on the wafer (33). The images of the overlay alignment marks (14, 24) are converted from space domain to frequency domain through Fourier transformations. The alignment measurements are performed by calculating the phase difference between the images corresponding to the repetitive patterns (14, 24) on different layers.

Abstract: In a method for electrically contacting thin-film solar modules interconnected in integrated fashion, a number of solar cells forming a module are created by structuring a layer on a substrate to produce strip-shaped, side-by-side solar cells, and electrically conductive contact strips are laid over the electrode layers of the two outermost, individual solar cells. The conductive strips are held in place by a lamination using hot-melt adhesive foil at elevated pressure and temperature, in the same step wherein a backing is laminated with the solar module. If necessary, the contact strips can be attached by an electrically conductive paste or utilizing an ultrasonic welding process.
