Abstract:
The present invention is drawn to hot-melt adhesives for bonding vitreous plastic materials to thermoplastic or thermosetting plastic materials, and to the use of these adhesives for making vehicle lamps or headlamps comprising lenses, especially bearing a scratch-proofing coating, made of a vitreous plastic material, and lamp bodies made of a thermoplastic or thermosetting plastic material, where the lenses and lamp bodies are bonded together with these hot-melt adhesives. The hot-melt adhesives of this invention are characterized in that they contain: a) from 0.5 to 15% by weight of optionally grafted thermoplastic elastomers; b) from 5 to 40% by weight of optionally grafted poly-&agr;-olefins except polyisobutylene; c) from 5 to 45% by weight of adhesive resins; and d) from 5 to 55% by weight of polyisobutylenes.
Abstract:
An apparatus and process for controlling the operation of a gas burner, by monitoring and controlling the stoichiometry of the air and fuel gas during the burning process.
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.
Abstract:
A method for producing a brazed joint having at least one of a metal/ceramic joint and a ceramic/ceramic joint. 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 burner apparatus for gas-fired appliances, such as gas furnaces. The burner apparatus includes an improved flame holder structure, with a contoured surface, for controlling the shape and contour of the flame, and burner housing and plenum configurations for enhancing the characteristics of the flame.
