Abstract: The energy transition involves the electrical power supply being almost completely covered by renewable energy sources such as solar plants or wind turbines. However, due to their naturally fluctuating output, these energy sources require the use of large energy storage systems, the realization of which still represents a major problem today. The present invention relates to supporting the construction of a large-scale pumped-storage power plant, e.g., in the Hambach open-pit mine, by enabling test operation as well as energy generation as early as during the construction phase.

Abstract: As underwater pumped storage power plant reservoir in a dry but floodable ground depression, comprises a modular arrangement of several individual pressure vessel modules for the intermediate storage of electrical energy from other power plants, wherein the pressure vessel modules each have an outer wall with at least one flow-through opening for letting in and/or letting out water and can each be filled with water and/or pumped empty independently of one another when the dry ground depression is flooded with water, and wherein the modular arrangement of the pressure vessel modules is designed in such a way that the pressure vessel modules are arranged with respect to one another in the dry ground depression with their outer wall face-to face adjacent to one another.

Abstract: The energy transition involves the electrical power supply being almost completely covered by renewable energy sources such as solar plants or wind turbines. However, due to their naturally fluctuating output, these energy sources require the use of large energy storage systems, the realization of which still represents a major problem today. The present invention provides a solution which aims to secure the entire short-term storage capacity needed for the energy transition in Germany (and even Europe). For this purpose, in particular, the invention proposes the construction of a large-scale pumped-storage power plant in the Hambach open-pit mine, as a result of which the can mine be put to subsequent use in a sustainable way. The invention also relates to the construction and partial commissioning of the plant in parallel with the use that is being phased out, in particular that of lignite mining (by 2038). This is to avoid the loss of a significant number of existing jobs.

Abstract: An integrated circuit includes stacked benzocyclobutene layers and a circuit geometry comprising conductive electric traces and interconnects on and/or extending through the BCB layers. A first said BCB layer formed and partially cured state. A top surface masked with photoresist, and after exposure, etched selectively form through vias at locations corresponding to conductive interconnects of the circuit geometry associated with said first BCB layer. A further mask coating is applied and after exposure, conductive metal is deposited to infill vias and form the electric traces of the circuit geometry. Subsequent BCB layers are then likewise formed, etched masked and coated in the same manner.

Abstract: The invention relates to a process for obtaining material of value from a bauxite residue which is obtainable or has been obtained by the Bayer process. This process comprises the steps of a) providing an aqueous suspension of the bauxite residue, b) setting a pH of the suspension to a value between 7.2 and 12.2, c) at least partly deagglomerating suspended mineral agglomerates of the bauxite residue, and d) separating the resulting mixture into an iron-rich fraction and into at least one further, preferably silicate-rich fraction. The invention further relates to an apparatus (10) for carrying out the process.

Abstract: An underwater pumped storage power plant that includes: an accumulator system with pressure vessels fillable with water and; a water outlet for water flow out of the system into a surrounding ocean against hydrostatic water pressure (PT) corresponding to water depth (T); a pump at the water outlet to pump water out of the system by converting electrical energy into potential energy corresponding to a displaced water column PT; a water inlet to allow water flow into the system from the surrounding ocean; a common generator at the water inlet, to convert the potential energy back into electrical energy when water flows in; electric lines to transport the electrical energy from the ocean surface to the power plant and back, wherein the pressure vessels are pressure-resistant and resistant to deformation from the PT at the ocean floor.

Abstract: A pumped storage power plant for a temporary reversible storage of energy, such as the energy available from wind power stations and/or photovoltaic systems that is fluctuating over time. The pumped storage power plant is designed as an underwater pumped storage power plant, wherein the ocean assumes the function of an upper storage basin and a pressure tank placed on the ocean floor serves as a lower storage basin. The storage of the electric energy takes place through pumping water out of the inside of the pressure tank against the hydrostatic water pressure on the ocean floor.

Abstract: A folding-top drive has a motor (13) that transmits forces to a first gear (14) and then to a folding-top linkage via a second gear (15). The first gear (14) and a guide (23) are pivoted to a housing (19) and a spring (22) acts on the guide (23). The first gear is guided on the guide (23) so that the guide (23) can be moved automatically with the first gear (14) counter to the force of the spring (22) from a first position where the gears (14, 15) engage to a second position where the gears (14, 15) are disengaged if a force on the first gear exceeds a defined limit. Additionally, the spring (22) can move the guide (12) automatically with the first gear (14) from the second position to the first position if the force on the first gear falls below the defined limit.

Abstract: An impact resistant provided PMMA moulding material according to DE 195 44 563 is process into a surface-hardened film which is highly glossy, essentially free of gel bodies and can be processed in the “in-mould-film-decoration” method. The melted mass is generated by means of an extruder and fed to the inventive glazing rolls via a flexible lip nozzle, said rolls being configured in order to generate an especially high locking pressure in the roll slit. The smoothing rolls are cambered. The films are used for decorating surfaces of high-value thermoplastic moulded parts.

Abstract: A method of producing a molded article includes the steps of positioning an insert within a first mold, and filling the first mold with a low melt allow to form a lost core assembly. The lost core assembly includes an external shape corresponding to the desired cavity formed within the molded article. The inserts are supported within the lost core and form a part of the surface of the cavity of the completed molded article. The lost core assembly is over-molded with a thermoplastic or thermoset material. The alloy material is removed leaving the inserts within the molded article to form specific portions of the cavity.

Abstract: A latch (1) for a top of a vehicle comprises a latching hook (3) which is disposed in a guide plate (10), preferably having a U-shaped cross-section, to be movable from a closed position into an open position on a defined path (41) via guiding means (bolt 8, pin 9). A geared motor (4) is provided for pivoting a actuation lever (15) which is connected to the latching hook (3). The connection between the latching hook (3) and the actuation lever (15) is realized through several levers (11, 12, 13) which are connected to each other in an hinged fashion. The motor-driven latch for a top with compact space-saving structure, has a latching hook with a larger radius of motion to increase the separation from the windscreen frame in the open position.

Abstract: A carrier assembly controls movement of a movable member within a mold tool to first receive a quantity of molten material, and then displace that molten material back into a mold cavity during solidification of a molded article. The moveable member moves relative to the surface of the mold cavity to compensate for local volume changes in a molded part that occur during solidification to substantially eliminate depressions and sink marks on an outer surface of a plastic injection molded part.

Abstract: A mold tool includes upper and lower sections defining a cavity within which a plastic film preform is placed before injection of plastic forming a molded article. The plastic film extends between an interface defined between the sections of the mold. The interface secures a position of the plastic film within the mold tool preventing movement during injection of plastic. The interface is specifically configured to secure the plastic film without damage. The specific configuration of the interface is determined according to a relationship between molding process parameters and physical characteristics of the plastic film.
