  • Patent number: 9795540
    Abstract: The present invention relates in a first aspect to an adhesion material for use in an individual containing encapsulated phase-change material. In particular, the adhesion material is for cosmetical or medicinal use in the body of an individual. The adhesion material contains encapsulated phase-change material having preferably a phase transition temperature above 40° C., like above 55° C. The adhesion material is particularly useful for adhering elements, like dental restorations, e.g. crowns or bridge, or brackets on elements in the body of an individual, like teeth or implants. That is, the adhesion material is particularly useful for adhering material in dental applications. In another aspect, a method is provided allowing removing a bracket, a crown or bridge, from implants, abutments or teeth. Furthermore, dental implant restoration systems and kits for permanent fixation of implants allowing improved removal thereof are provided.

  • Publication number: 20170237355
    Abstract: The invention relates to a DC-DC converter as well as to a DC network having a DC-DC converter, and to a method to operate a DC network having a DC-DC converter, whereby the DC-DC converter comprises a circuit arrangement with two bridge connections having semiconductor switches and a transformer arranged between the bridge connections. The transformer is provided with a step switch by means of which the transformation ratio can be switched. Through the selection of the transformation ratio, the soft-switched range of the dual active bridge in the form of the DC-DC converter can be enlarged. Consequently, a purely capacitive snubber can be used as the snubber, as a result of which the switching losses can be reduced.

  • Publication number: 20170114810
    Abstract: A method for producing a bonded joint between a light metal of a first component and a steel material of a second component, wherein a protective-gas joining process is used, a zinc-based filler material is used, and wherein an arc of the protective-gas joining process reaches at least the steel material of the second component, wherein a phase space of at least intermetallic phase composed of iron and the light metal is produced in a joining region adjacent to the steel material. Introduction of heat occurs so that the joint to the steel material is a solder or brazed connection and, during joining, a detachment of part of the solidified intermetallic phase(s) from the steel material of the second component starts in a melt of a solder or brazed matrix formed by the filler material and the at least one intermetallic phase is embedded in the solder matrix.

  • Publication number: 20160160634
    Abstract: A device and a method is disclosed for detecting an undesired escape of fluids, in that electric potentials are measured using a grid of non-polarizable measuring electrodes above an underground storage facility. Potential differences are determined in such a way that disturbances due to injection borehole or due to the exchange of fluids in the underground storage facility are eliminated. This is done either through the use of the symmetry of the potential distribution around the injection borehole in that the potential differences of pairs of measuring electrodes are observed whose mid-points coincide with the injection borehole or else through the computational simulation of the potentials that arise due to the fluid movement in the underground storage facility without a leak. These are then subtracted from the measured potentials. If the ascertained potential differences exceed a limit value, this is considered as an indication of a leak.

  • Patent number: 7989730
    Abstract: The present invention relates to a method for determining a lateral relative movement between a processing head and a workpiece during processing the workpiece as well as a device to carry it out. In the method a surface of the workpiece (12) is illuminated in the region of the processing head with an optical radiation (2). The optical radiation (3) reflected from the surface of the workpiece (12) in the region of the processing head is repeatedly detected in a locally resolved manner by an optical detector (9), which is firmly fixed mechanically to the processing head, to obtain optical reflection patterns. The repeated detection occurs in temporal intervals in which the temporally successive reflection patterns of overlapping surface regions of the workpiece (12) are obtained. The lateral relative movement is determined by comparing the temporally successive reflection patterns.
