Abstract:
A gas turbine, comprising a turbine and a compressor provided with a compressor housing, and to a method for the operation thereof. The compressor is tapped in order to cool the turbine by means of at least one tap line for removing compressed or partially compressed air. The tap line comprises a locking device, particularly a valve, in order to regulate the outflow of tapped air and thus the cooling of the housing.
Abstract:
This invention describes novel methods for fabricating nano/micro particles and capsules through template decomposition which incorporates the to-be-encapsulated molecules which are precipitated in pores of particles or in solution, i.e. below their isoelectric point, drying or by solvent adjustment methods. The encapsulation process can be followed by a deposition or adsorption of a protective shell that regulates release of the encapsulated material. The encapsulation, inclusion, manipulation, and release of various materials and bio-materials is to be conducted by delivery vehicles which are particles and capsules with sizes in the range of nanometers and micrometers. They can possess multicompartment and anisotropic geometries and can carry one or several types of various molecules. This invention can potentially be used for controlled delivery, manipulation, and release in a variety of applications requiring delivery vehicles such as cell cultures, in-vivo, subcutaneous incorporation, injection, spray-inhalation and planar surfaces, films, and stents.

The method includes forming bores in at least one ceramic surface to be brazed, and the bores have an average diameter of greater than 550 μm. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
Abstract:
A hot-melt adhesive contains a non-pressure-sensitive adhesive that is fluid at application temperatures and that is removable, residue-free, by peeling at small peel angles. The adhesive contains additives selected from the group consisting of fillers, stabilizers, dyes, carbon black, and moisture absorbents. The adhesive also containing the following: a) thermoplastic elastomers that may be grafted, b) grafted and poly-α-olefins, c) polyisobutylene or a softening oil, d) adhesive resin, and e) end block resin.
Abstract:
The invention relates to a culture substrate having thermoresponsive microgel particles that have a thermoresponsive polymer and modulator particles fixed to the carrier area of the substrate. The modulator can be a substance that has an adhesion capability with biological cells or a substance that causes cellular reactions that are inducible to binding to surface receptors of biological cells. Methods for preparation and use in culturing cells are given.
Abstract:
A substrate (10), in particular for receiving biological cells (21) comprises a substrate body (1) which has a support area (2) on which there are fixed thermoreactive microgels (3) which comprise particles containing a thermoreactive polymer. Also described are a process for the preparation of the substrate (10) and a method for culturing biological cells (21) on the substrate (10).
Abstract:
A method for producing a component having a base body made of a carbon fiber reinforced ceramic and a protective layer which is applied on the base body includes the following steps: providing the base body: applying a first layer on the base body, the first layer comprising a slip with reactive carbon; applying a second layer on the first layer, the second layer comprising a slip with silicon. The application of the layers can be carried out by painting, brushing, filling or dipping techniques, or by fully automatable spraying devices. Finally, the silicon of the second layer is liquefied in a thermal treatment, so that the liquid silicon penetrates into the first layer and forms with the reactive carbon a reaction protective layer composed of a silicon carbide compound.
Abstract:
Disclosed is a gas turbine for a thermal power plant, especially a gas turbine, comprising a rotatable rotor and a duct which can be penetrated by a gas and in which turbine blades for driving the rotor are disposed. The inventive gas turbine is characterized by a blocking device which at least partially prevents the gas from penetrating the duct in a closed position.
