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 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 invention relates to components for fusing vertebral bodies and to methods for the production and use thereof.


The invention relates to a rotary bend testing device for plate-like substrates (1) made of ceramic or glass-ceramic materials, wherein the substrates (1) to be tested are subjected to bending. In order that uniform checking both of the top side and of the underside of the substrate (1) takes place in the rotary bend testing device, without the substrate (1) having to be turned over, it is proposed that a first roller arrangement (3) consisting of at least three support rollers (3a, 3b, 3c) arranged on shafts is arranged on a mounting platform (8), all the support rollers (3a, 3b, 3c) running on the same first plane on a first circular track, that a second roller arrangement (2) consisting of at least three pressure rollers (2a, 2b, 2c) arranged on shafts is arranged above or beneath the first roller arrangement (3), wherein all the pressure rollers (2a, 2b, 2c) run on the same second plane on a second circular track, that the centre (10) of the first and the second track is arranged on a centre straight line perpendicular to the two planes and the support rollers (3a, 3b, 3c) are arranged in an offset manner with respect to the pressure rollers (2a, 2b, 2c), i.e. one roller of one roller arrangement is arranged between in each case two rollers of the other roller arrangement, all the rollers from one of the two roller arrangements are driven at the same speed via a drive apparatus and the second roller arrangement (2) is displaceable on the centre straight line.


The present invention relates to a securely adhering layer on ceramic and/or soldering resist which comprises a potting compound or a protective lacquer. The potting compound or the protective lacquer in this case is a plastics-based compound. In addition, the present invention relates to a method for producing such a securely adhering layer, in which method i) a ceramic substrate is roughened in an etching bath, ii) the ceramic substrate thus roughened is metallized by means of a metal paste, iii) the ceramic carrier thus metallized is processed to form a small ceramic chip with a housed LED or to form an open LED chip, iv) the housed LED or the open LED chip is connected to further electronic components on the metallized ceramic carrier, and v) a potting compound or a protective lacquer, which is a plastics-based compound, is applied to the carrier ceramic thus populated. Finally, the present invention also relates to a structural part having such a securely adhering layer.

Patent
CeramTec GmbH | Date: 2017-04-05

The invention relates to a control cartridge (1) for a single-lever mixer tap comprising a housing (2) in which a ceramic base disk (3) is arranged and a ceramic control disk (4) is placed to be rotatable and displaceable on the base disk (3), wherein an intake (5a, 5b) for the cold and hot water and an outlet (6) for the mixed water are respectively arranged in the base disk (3) and the mixed water is diverted in the control disk (4) by 180 and leaves the control cartridge (1) via the outlet (6) in the base disk (3). In order that an automatic scalding protection is integrated into the control cartridge (1), i.e. that the control cartridge automatically closes in the event of a scalding temperature of the mixed water, at least one SMA (shape-memory alloy) element (7) is arranged according to the invention on the control disk (4), which SMA element takes on the temperature of the mixed water during operation of the control cartridge (1) and upon achieving a scalding temperature of the mixed water expands and by this means automatically displaces the control disk (4) into the closed position in which no water arrives at the outlet (6), and the SMA element (7) is supported on the one side on the control disk (4) and on the other side on the housing (2).


The invention relates to a ceramic support body (1) on the surface of which metallization regions (2) which are sintered on one side or on several sides are fitted as conductor tracks, and the support body (1) is a printed circuit board, wherein at least one LED (3) and possibly other electrical or electronic components (4) are arranged on the support body (1). In order that the support body (1) emits the light from the LEDs (3) in all spatial directions, can be used in the high-power range (starting from approximately 0.8 W per LED) and has a thermal conductivity of greater than 10 W/mK, it is proposed that the ceramic support body (1) is a translucent ceramic.
