Abstract: A process is described for preparing hydrolytically and hydrothermally stable, consolidated proppants, in which (A) a consolidant comprising a hydrolyzate or precondensate of at least one organosilane, a further hydrolyzable silane and at least one metal compound, where the molar ratio of silicon compounds used to metal compounds used is in the range from 10 000:1 to 10:1, is blended with a proppant or infiltrated or injected into the geological formation, and (B) the consolidant is cured under conditions of elevated pressure and elevated temperature.

Abstract: A consolidation agent for moulded articles and geological formations from porous or particulate materials, containing a hydrolysate or precondensate of (a) at least one organosilane of the general formula (I) RnSiX4-n ??(I) in which the radicals R are identical or different and are not hydrolytically removable groups, the radicals X are identical or different and are hydrolytically removable groups or hydroxyl groups, and n is 1, 2 or 3, and optionally (b) at least one hydrolyzable silane of the general formula (II) SiX4 ??(II) in which the radicals X have the meaning defined above.

Abstract: An insulation material comprising an inorganic, porous matrix, a process for producing it and its use are described. The moldings and coatings obtained therefrom display excellent insulation against heat and cold and can be used over a wide temperature range.

Abstract: The invention relates to corrosion-resistant, temperature-stable, durable mould release layers, suitable for the die casting of non-ferrous metals, comprising boron nitride and slips for production thereof, a method for production of the slips, a method for production of the mould release layers and the use of the mould release layers.

Abstract: A substrate having an anti-adhesive coating thereon. The coating is made from a coating composition comprising solid particles of a release agent different from boron nitride and a binder comprising surface-modified nanoscale solid particles.

Abstract: A sectional mounting connector is provided for mounting a component on a printed circuit board, characterized that the sections of the component are arranged end to end in interlocking relation.

Abstract: A method of manufacturing a substrate coated with a transparent, colored coating stable to high temperature and UV includes coating the substrate with a coating composition including at least one element which is able to form a vitreous, crystalline, or partially crystalline oxide, in the form of a compound which on heat treatment yields the oxide and is present as a sol or solution in an at least predominantly aqueous medium, as the matrix-forming component, and at least one member selected from the group consisting of metal colloids, metal compound colloids, metal alloy colloids, and metal compounds which form metal colloids under reducing conditions, as the coloring component; and heat-curing the resulting coating. Particularly suitable substrates are glass substrates, such as (halogen) lamp bulbs and gas discharge tubes.

Abstract: A resilient connector for maintaining an electrical conductor in side-by-side conductive engagement with a bus bar includes a generally loop- or O-shaped resilient contact body having a first end portion, an intermediate portion arranged generally normal to the intermediate portion, and a second end portion that is normally arranged at an acute angle relative to the contact intermediate portion, the contact first end portion containing a window opening having first and second opposed edges remote from and adjacent the intermediate portion, respectively, the second contact end portion being displaceable from a normal first position adjacent the first window edge toward a second position adjacent the second window edge, whereby when the second contact end is displaced to its second position and a conductor and a bus bar are introduced in side-by-side electrically conductive relation within the window, release of the second end portion causes the conductor and the bus bar to be clamped in tight electrical contac

Abstract: An actuating device is provided for closing and opening a door or lid lock and correspondingly switching a light on and off during the opening and closing of the door or lid. This actuating device also makes it possible to switch off the light permanently when the door or lid is open, because the switch is switchable indirectly per se as a result of movements of a rotary latch and can be switched manually into its switch-off position independently of the actuating device.
