The present invention relates to effect pigments based on uncoated or coated flake-form substrates having an outer coating comprising a) TiOand b) AlO, MgO and/or CaO and c) SiOand d) ZnO and/or e) at least one mixed oxide of the elements mentioned under a) to d), and to the use thereof, inter alia in paints, coatings, printing inks, plastics and cosmetic formulations.

Effect pigments

The present invention relates to pearlescent pigments based on glass flakes which are distinguished by the fact that they have the following layer structure: A) optionally a layer of SiO, B) a high-refractive-index coating have a refractive-index n&#x3e;1.8 which essentially consists of TiO, C) a low-refractive-index layer comprising SiOand/or AlOand optionally D) an outer protective layer, and to the use thereof in paints, coatings, automobile paints, powder coatings, printing inks, security printing inks, plastics, ceramic materials, glasses, paper, in toners for electrophotographic printing processes, in seed, in greenhouse sheeting and tarpaulins, as absorbers in the laser marking of paper and plastics, as absorbers for the laser welding of plastics, in cosmetic formulations, for the preparation of pigment pastes with water, organic and/or aqueous solvents, for the preparation of pigment compositions and dry preparations.

A lamp with an unpolished surface is herein described. The lamp comprises a closed body which comprises a source of light adapted to be connected to a source of power, contacts to connect said source of light to a source of power, and a cover. The cover is configured and disposed to permit light to exit the lamp when connected to a source of power. The cover comprises an inner surface facing the interior of the lamp and an outer surface facing away from the lamp. At least the outer surface facing away from the lamp comprises unpolished glass configured to provide the unpolished surface. The unpolished glass of the outer surface comprises a surface having a roughness which is minimized.

A building for containing occupants, with at least one covering element to provide at least one roof portion, at least one wall portion, and at least one floor portion, to provide an interior space to contain and protect occupants from an adverse environment about the building or other structures. The building has an opening to permit occupants to ingress and egress, a window comprising at least one pane, comprising at least an outer pane disposed to contact the adverse environment about the building and at least one inner pane disposed toward the interior space of the building. The pane exposed to the environment about the building or structure comprises a glass material that has a minimized coefficient of thermal expansion. The building also has an insulation to protect occupants from adverse temperature and environmental conditions about the building and a heating apparatus to provide heat to the space provided by the at least one covering element, the window, and the insulation.

A cooking surface for a cooktop. Encrusted, spilled, or overflowing food is deposited on the cooking surfaces of cooktops during cooking and the removal of such residue is difficult because the surface of a cooktop is typically rough and uneven. The invention teaches the manufacture of an easy-to-clean glass ceramic cooktop from a floated glass ceramic. As a result of the increased use of controls in cooking devices, an increased number of displays are also being used under the surface of the cooktops. The invention provides a cooktop with a smooth, distortion-free surface that is easy to clean. The invention also relates to window panes for enclosed hot areas with high temperatures, which are typically made of transparent glass ceramic. When used as windows in warming stoves or in self-cleaning ovens, combustion residues are thereby deposited on the windows, which residues must then be removed. It is difficult to clean a window of this type, because the surface of the transparent glass ceramic that is manufactured using conventional methods is typically structured and uneven. The invention teaches the manufacture of an easy-to-clean class ceramic window body from a floated glass ceramic that has a specified surface quality that is comparable to that of a floated soda lime glass pane. The invention also relates to a stove for cooking food with an easy-to-clean oven window and an easy-to-clean cooktop.

Cooking arrangement for cooking food such as a stove, a cooktop, and other cooking appliances, with an easy-to-clean surface

A multipane insulating glass for appliances having an inner-chamber temperature which is lower than the ambient temperature, in particular for viewing doors of refrigerators and freezers comprises at least two panes which are of approximately equal size and are arranged at a distance from one another. The distance is maintained by a spacer which runs continuously around the vicinity of the edge. One of the two outer panes is provided with an electrically conductive, transparent coating on its side which faces towards the space between the panes. In this glass, the coating, which is applied to the entire surface, is deactivated in the peripheral area of the pane, containing the contact surface for the spacer. Also, a process for producing coated flat glass materials for such insulating glass materials, as described above.

The invention is directed to a method of producing a chemically pretensioned glass body. In the method, a glass body is provided having a composition in percent by weight on oxide basis: SiO.sub.2 70-85; B.sub.2 O.sub.3 8-15; Na.sub.2 O 1-5; K.sub.2 O 1-&lt;5; Al.sub.2 O.sub.3 1-5; MgO 0-3; SrO+BaO 0-2; CaO 0-3; ZnO 0-3; with CaO+ZnO 2-6; and, ZrO.sub.2 0-3.5. The glass body is placed in an ion exchange salt bath containing at least 90% by weight of potassium salts. The salt bath is maintained at a temperature below the transformation point Tg of the glass defined by the glass composition for a duration of at least 2.0 hr causing potassium ions from the salt bath to migrate into the surface region of the glass body to thereby produce the chemically pretensioned glass body.
