摘要:
The invention relates to a cold and/or heat accumulator comprising a first heat exchanger and preferably a second heat exchanger. The first heat exchanger may, in particular, be provided to be perfused by a refrigerant while the second heat exchanger is preferably perfused by brine. The first heat exchanger and preferably also the second heat exchanger are engaged in a heat-exchanging relationship with carrier elements charged with a cold or heat storage medium and may, in particular, be formed by graphite strips. The cooling energy and/or heat accumulator according to the invention exhibits a good heat conduction, short charging times, a high cooling or heating performance, low pressure losses as well as a good cooling agent distribution. Further its integration options are manifold due to the selected fixation means.

In accordance with the invention a method for the manufacture of an erosion protection layer on a metallic substrate is proposed in which a material is welded onto the metallic substrate (2, 2′). The material is a steel which contains at least 0.1% carbon and at least 12% chrome. The material is applied to the substrate (2, 2′) by laser deposition welding. A component (1, 1′) is further proposed by the invention with a metallic substrate (2, 2′) and an erosion protection layer (3, 3′) applied on the substrate (2, 2′), wherein the erosion protection layer (3, 3′) is manufactured using a method in accordance with the invention.
摘要:
The present invention is an attachment that fits onto the head of a wrench to magnetically hold a nut. The attachment has a magnetized surface and a side surface to friction fit onto a wrench. Fit is further improved by magnetizing the side surface. By holding the nut, the attachment allows for operation of a wrench in restrictive spaces where manual holding of the nut would be impossible or impracticable. Making side surfaces of the attachment out of plastic allows the attachment to adapt to different sizes of wrench heads. A hole in the attachment allows a bolt to pass through the attachment as it passes through the nut.

The present invention relates to a non-human vertebrate animal model displaying an alteration in fat metabolism or in the sensitivity towards leptin or insulin, which model bears a mutation in the gene encoding the spinster like 1 protein (Spinl1). The invention also relates to mutant Spinl1 proteins and nucleic acid sequences encoding these proteins. Furthermore, the invention relates to the use of the non-human vertebrate animal model for the identification of diagnostic markers, or as a model for studying the molecular and physiological mechanisms associated with an alteration in fat metabolism or an alteration in the sensitivity towards leptin or insulin, or for the identification and testing of agents useful in the prevention, amelioration, or treatment of the above conditions. Agents, pharmaceutical compositions, and methods for treating the above conditions are likewise described, as are methods for identifying said agents.
摘要:
A method for detecting at least one substance (a ligand) present in a compound library using at least one additional substance (a receptor) that binds to the ligand comprises adding to the compound library such a receptor that has substantially higher molecular weight than the ligand to be identified, and performing of such a spectroscopic measurement technique with the mixture, without isolating the receptor-ligand complex, that can detect those dipolar resonance phenomena which occur upon a binding of a receptor to a ligand.
