Abstract: The present invention relates to a brake for a vehicle, comprising a disc and a shoe device. The disc comprises a braking band of a first material and a support bell of a second material. The braking band e comprises a radially inner track and two opposing friction surfaces which are planar and suitable to interact with a brake caliper. The support bell is suitable to be structurally connected to the braking band. The shoe device is suitable to radially act on the inner track.

Abstract: A paint is formulated by combining fine boron nitride powder with a polymeric dispersion and a volatile liquid carrier, which paint is coated on ceramic preforms and subjected to hot pressing. The paint eliminates the formation of undesirable carbides on the surface of the pressed ceramic.

Abstract: The present invention provides an optical display device including a liquid crystal display integrated into a multilayer ceramic substrate assembly. The ceramic substrate may include cavities in which are embedded integrated circuits which activate the display. A three-dimensional electrical conducting network is used to interconnect the integrated circuits with a display pattern etched in a metalized layer on one surface of the ceramic substrate. Electrical connections to the display pattern are made directly from within the substrate, thereby eliminating the need to etch electrical access leads in the metallic surface. A single upper conducting plate is separated from the ceramic substrate by a window-like conducting spacer to form a cell in which a liquid crystal material may be contained. No display pattern nor electrical access leads are etched in the upper plate. Instead, the conducting spacer provides the only electrical connection to the upper plate.
