Patents by Inventor Paul Bernhard

Paul Bernhard has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Crystal forms of (3R)-1-(2-methylalanyl-D-tryptophyl)-3-(phenylmethyl)-3-piperidinecarboxylic acid 1,2,2-trimethylhydrazide
    Patent number: 8466173
    Abstract: Crystalline polymorphs of (3R)-1-(2-methylalanyl-D-tryptophyl)-3-(phenylmethyl)-3-piperidinecarboxylic acid 1,2,2-trimethylhydrazide which are useful as pharmaceutical agents are disclosed. Methods of production and isolation of these polymorphs and pharmaceutical compositions which include these polymorphs and pharmaceutical methods of treatment are also disclosed. The crystalline polymorphs of the present invention are useful as they act directly on the pituitary gland cells to release growth hormone.

  • Process for the polymerization of cyclic olefins and polymerizable composition
    Patent number: 5854299
    Abstract: Process for the polymerization of cyclic olefins by photochemical ring-opening metathesis polymerization by irradiation, using catalytic amounts of a heat-stable ruthenium or osmium catalyst which has at least one photolabile ligand, the other coordination sites being occupied by non-photolabile ligands.
    Type: Grant
    Filed: March 8, 1996
    Date of Patent: December 29, 1998
    Assignee: Ciba Specialty Chemicals Corporation
    Inventors: Andreas Muhlebach, Paul Bernhard, Andreas Hafner, Thomas Karlen, Martin Andreas Ludi
  • Process for adjusting the sensitivity to radiation of photopolymerizable compositions
    Patent number: 5645973
    Abstract: A process is described for the preparation of photopolymerizable compositions, wherein the photopolymerizable compositions can be photopolymerized by the irradiation of emission lines of differing wavelength from a UV/VIS laser light source, and contain a photopolymerizable compound and at least two photoinitiators, by adjusting the sensitivity to radiation. The ratio between the concentrations of the individual photoinitiators is so adjusted that the composition has virtually the same optical density for the radiation of the different emission lines at which the photoinitiators are effective.
