Abstract: A method and a device for determining the minimum hydraulic injection interval of a piezo-servo injector are described. The closing time of the nozzle needle of the injector is determined on the basis of the characteristic pressure profile in the control spring chamber of the injector. By incrementally reducing the injection interval of a subsequent injection by successively advancing the timing of the start of actuation of a subsequent injection and continuing to observe the pressure profile in the control spring chamber, the smallest injection interval is obtained from the last iteration step in which closing of the nozzle needle of the preceding injection could still be detected in the characteristic pressure profile. Particularly precise determination of the minimum injection interval is possible with this method.

Abstract: The invention relates to a method for the production of a dental prosthetic moulded part, such as a partial or total prosthesis, which is produced in a multilayered manner from a generatively produced solid body model of at least one prosthetic tooth or of a prosthetic dental arch, wherein, inside, tooth neck-sided, the prosthetic teeth have a lumen, in which a dentin-hued, polymerisable composition is filled. The composition is subsequently polymerised in at least one step. The at least one prosthetic tooth with dentin-hued composition is arranged, with its cervical side, on the tooth-sided surface of the denture base and compacted. Subsequently, the partial or total prosthesis obtained is completely cured in a light curing device. The prosthetic moulded parts obtainable according to the method according to the invention are also a subject matter of the invention.

Abstract: A method is provided for determining the fuel temperature in the high-pressure zone of a fuel injection system of a motor vehicle. The fuel injection system has at least one injector operated by a servo valve which is actuated by means of a piezo actuator. After an injection process has been carried out, the piezo actuator is discharged after the injection has ended in such a way that the servo valve can close, but a non-positive connection remains between the piezo actuator and the servo valve. This condition of reduced charge is maintained. The pressure oscillation of the actuator voltage resulting from this is recorded and from this the hydraulic natural frequency of the enclosed high-pressure volume of fuel is deduced. The prevailing fuel temperature can be determined from the natural frequency.

Abstract: A container system for particles of a tire-balancing material has a first container for holding the particles and a second container for holding at least one accessory such as a tire-valve core. The second container is connected to the first container and a perforation is provided between the first container and the second container. The first container has a duct dimensioned to release the particles, and oriented towards the second container. The duct is sealed by the second container as a result of connection between the first and second containers. Before use, the first container is opened by separating the second container along the perforation. The opened first container is placed in a tire, where the duct facilitates a smooth flow of the particles from inside the first container into the tire. The tire-valve core is removed from the second container and applied to the wheel.
