  • Publication number: 20140241887
    Abstract: A hydrodynamic axial bearing for mounting a shaft which is mounted rotatably in a bearing housing, including an axial stop of the bearing housing and a bearing comb which rotates with the shaft. A lubricating gap, which is loaded with lubricating oil and is delimited by a profiled circular ring face and a sliding face, being formed between the axial stop and the bearing comb. The profiled circular ring face and the sliding face are configured in such a way that the lubricating gap is constricted radially to the outside with regard to the axial direction. As a result, temperature deformations which occur during operation and deformations on account of centrifugal, shearing and other forces in the bearing comb can be compensated for.

  • Patent number: 8362159
    Abstract: Disclosed is a biocompatible block copolymer containing the polycondensation product of a diol and an additional component selected from the group of the same diol, an ?,?-dihydroxy-polyester or an ?,?-dihydroxy-polyether. Also disclosed are a medical implant containing the block copolymer, the use of said block copolymer for the production of a medical implant, a diol and a method for the production thereof. The diol may be obtained by transesterification of ?,?-dihydroxy-[(oligo(3-(R)-hydroxybutyrate)-ethylene-oligo-(3-(R)-hydroxybutyrate)] with diglycolide. Transesterification is carried out, preferably, in the presence of a catalyst.

  • Patent number: 5451314
    Abstract: A plant (200) for treatment of drinking water from raw water has a treatment tank (202) which is supplied with raw water and a storage tank (204) placed downstream of the treatment tank. The treatment tank supplies water on demand to a point of use (224). The treatment tank and the storage tank are connected by a conduit (206), with a pump (208) to feed water from the treatment tank to the storage tank, and by an overflow pipe (210) to feed water back from the storage tank to the treatment tank. The pump is activated by a command device to feed sufficiently treated water to the storage tank when water is consumed at the point of use and when water in the treatment tank is re-ozonized at intervals between times of consumption of water at the point of use. In the latter case, water from the storage tank flows back to the treatment tank through the overflow pipe so that it can be reozonized in the treatment tank.
