A process is disclosed for fabricating lightweight honeycomb type structures out of material such as silicon carbide (SiC) and silicon (Si). The lightweight structure consists of a core (10) to define the shape and size of the structure. The core is coated with an appropriate deposit such as SiC or Si to give the lightweight structure strength and stiffness and for bonding the lightweight structur...

The present invention refers to a liquid curtain apparatus comprising two windowpane blades made from glass or another transparent material paralel to each other and joined along as peripherical edges in order to define an closed inner space therebetween, a container for storing a liquid able of reducing or eliminating the transmission of light and the radiation of heat through said blades, said c...

A locking mechanism is provided which is characterised by one or more blocking elements each consisting of two complementary semi-cylindrical parts (2), (3) snugly located in a correspondingly shaped aperture (4) defined between two relatively movable parts (5), (6) to be locked together, one of the semi-cylindrical parts (2), (3) being adapted to be operatively coupled to a key (8) to permit rota...

The invention relates to a high-temperature heating element having a substrate of aluminium nitride and, applied thereon, a heating conductor, and a method for producing said heating element. High-temperature heating elements are used in the motor vehicle industry for producing ceramic heating devices, in particular for producing spark plugs and glow attachments (heater attachments). The disadvant...

A room temperature-curable composition comprising (A) a silanol-terminated polydiorganosiloxane having a viscosity measured at 25 DEG C. of from 100 to 200,000 cSt, (B) an epoxy-terminated polyether, (C) an organosilicon compound, (D) an inorganic filler, and (E) a curing catalyst. The composition is suitably used as a building sealant which causes no fouling of the areas surrounding joints even ...
