Patent number: 7186447Abstract: Described are matrix liquid crystal displays having two plane parallel support plates which together with a frame form a cell, integrated non-linear elements for switching individual picture elements on the support plates and a nematic liquid crystal mixture which is present in the cell and has a positive dielectric anisotropy and high resistivity. The liquid crystal mixture has a nematic phase range of at least 60° C., a maximum viscosity at 20° C. of 30 mPa·s and a mean dielectricity constant ??8. The liquid crystal mixture contains: a) at least 10% by weight of a liquid-crystalline component B having one or more compounds of the following formulae: and b) up to 90% by weight of a liquid-crystalline component A having one or more compounds with a dielectric anisotropy of ?1.5 to 1.Type: GrantFiled: March 17, 2005Date of Patent: March 6, 2007Assignee: Merck Patent GmbHInventors: Georg Weber, Ludwig Pohl, Reinhard Hittich, Herbert Plach, Bernhard Scheuble, Takamasa Oyama, Bernhard Rieger, Hans Adolf Kurmeier, Ekkehard Bartmann

Patent number: 7090986Abstract: A naturally occurring protein isolated from the saliva of the medicinal leech Hirudo medicinalis is described which strongly binds to collagen thus acting as an inhibitor of natural platelet adhesion to collagen. The protein has a molecular weight of about 12,000, an acidic isoelectric point and contains six cysteins. The protein was sequenced and the gene was cloned from a H. medicinalis cDNA-library. Procedures for producing such polypeptide by recombinant techniques are disclosed. The recombinant and the natural occurring proteins are potent inhibitors of collagen-dependent platelet adhesion and therefore useful for the therapeutic treatment of various conditions related to heart disease and diseases of the circulation system. Furthermore, the protein is useful for coating natural or artificial collagen surfaces in order to render them nonadhesive for cells and prevent the activation of cells.Type: GrantFiled: June 16, 2005Date of Patent: August 15, 2006Assignee: Merck Patent GmbHInventors: Wolfgang Strittmatter, Detlef Güssow, Uwe Hofmann, Jürgen Hemberger, Zisi Fotev, Bernhard Scheuble
