The invention relates to a control cartridge for single-lever mixer taps, comprising a housing in which a ceramic base disk and a rotatable and displaceable ceramic control disk resting on the base disk are situated. An inlet for the cold water and hot water, respectively, and an outlet for the mixed water are situated in the base disk, and the mixed water is diverted in the control disk and leaves the control cartridge via the outlet in the base disk. In order for automatic scalding protection to be integrated into the control cartridge, i.e., for the control cartridge to automatically close in the event of a scalding temperature of the mixed water, according to the invention at least one shape memory alloy (SMA) element is situated on the control disk, and takes on the temperature of the mixed water during operation of the control cartridge, and upon reaching a scalding temperature of the mixed water, expands and hereby automatically moves the control disk into the closed position in which no water arrives at the outlet, and the SMA element is supported on the one hand on the control disk and on the other hand on the housing.


The invention relates to control cartridge (1) for single-lever mixer batteries, comprising a housing with a cylindrical housing wall (2) and with a base (3) comprising a bore for an inlet (3a) for cold water and a bore for an inlet (3b) for hot water. Three ceramic disks (5, 6, 7) which lie one above the other are arranged on the base (3), namely a lower base disk (5) with a bore for the inlet (5b) for hot water and a bore for the inlet (5a) for cold water, a ceramic control disk (6) which rests on the base disk (5) in a rotatable and movable manner and which comprises a control edge (8) on the circumferential surface, and an upper storage disk (7) which is sealed from the housing or the housing wall (2). In order to allow the outlet of mixed water to occur either laterally or vertically while maintaining the same installation space or the same installation height and installation diameter, the base (3) and the base disk (5) each have a mixed water outlet (9) together with the two inlets for cold and hot water (3a, 3b, 5a, 5b). The inlets for hot water (3b, 5b) and for cold water (3a, 5a) and the mixed water outlet (9) are arranged in the base (3) and the base disk (5) so as to lie one over the other. The base (3) is sealed from the housing wall (2), and depending on the requirements, the housing wall (2) has an opening (10) for a lateral mixed water outlet or no opening in the housing wall (2) for a vertical mixed water outlet.

The invention relates to a carrier body (1) for solar cells (2). According to the invention, in order to significantly improve the thermal resistance of the connection between a solar cell (2) and the carrier body (1) or a cooling body, the carrier body (1) is made of a ceramic material having sintered metalisation regions (3), at least one solar cell (2) is soldered or sintered onto the carrier body (1) and electrically connected to the metalisation regions (3), and the carrier body (1) has ceramic cooling elements.

The invention relates to a piezoceramic sensor in a housing having a layer (3), preferably a PZT layer, made of a piezoelectric material, on both sides of which there is a respective sensor electrode (2), both sensor electrodes (2) being connected in each case to a pole (5, 6). In order that no potential difference, which would allow for the charge to be dissipated by way of the surface, is formed between the housing and the sensor electrodes (2), it is proposed according to the invention that the layer (3) protrudes beyond the sensor electrode (2) on at least one side of the layer (3), and a protective electrode (1) which encompasses the sensor electrode (2) at an insulating distance (7) is arranged on that part of the layer (3) which protrudes beyond the sensor electrode (2).


The invention relates to a knee joint prosthesis comprising a femoral component (1) and a tibial component (2), each having a front face constituting the joint and a rear face (4) facing the bone, and a polyethylene (PE) liner (3). In order to allow the knee joint prosthesis to be implanted without metal and without cement, the femoral component (1) and the tibial component (2) consist of a full ceramic material and both components (1, 2) have integrated porous osseointegrative rear faces (4) facing the bone.

The aim of the invention is to provide more space for additional circuit elements (coils, capacitors) and/or to allow the accommodation of additional circuit elements required for shielding the circuits. This is achieved in that the metallization regions are arranged one over the other on at least two metallization planes. The support element (1) has a surface on which sintered metallization regions are arranged on a first metallization plane, said metallization regions supporting electronic components and/or being structured such that the metalization regions form resistors or coils. The metallization regions together with the components and/or the formed resistors or coils are covered by a ceramic plate (5), and optionally additional metallization regions are arranged on additional metallization planes on the ceramic plate and each metallization region is covered by a ceramic plate. Sintered metallization regions are arranged on a metallization plane for receiving circuit elements on the topmost ceramic plate (5) facing away from the cooling elements.

The cerAMfacturing project will develop a completely new approach for ceramic multi material additive manufacturing which will allow series production of customised and multifunctional components for manifold applications for obtaining property combinations, like electrical conductive/electrical insulating, dense/porous or two-colored components. In five case studies demonstrators for personalized medical products micro surgical tools, implants, and remedies such as consumer products will be manufactured starting with the patient specific physical dimensions and ending with components validated under practically relevant conditions. For achieving these goals manifold tasks will be solved starting with method and device development. Especially suspension based additive manufacturing methods will be developed and qualified in cerAMfacturing, because this route promises a much better component performance in comparison to powder based methods. Multi material applications play a dominant role in the project. Beside ceramic/ceramic also ceramic/metal material combinations will be developed. For that purpose either additive manufacturing methods will be qualified or AM methods will be combined with conventional shaping routes like tape casting or ceramic injection moulding. The last mentioned combination of technologies will allow the individualisation of large series production components. Appropriate control methodologies to guarantee a high quality level of the custom made products will be implemented. The cerAMfacturing project will provide the technical equipment for combining AM steps with conventional ceramic shaping routes.

The invention relates to a hip joint prosthesis comprising a ceramic inner sliding cup that, on its outside, is surrounded by a plastic covering, for inserting into an outer metal cup or for directly implanting with the aid of bone cement. A ball head, which is mounted on a shaft, articulates inside the inner sliding cup, and said shaft can be anchored inside the femur. In order to increase the strength with regard to tilting and turning, the exterior of the sliding cut is provided with a structuring.
