Abstract: The invention relates to a method of manufacturing a curved automobile glass pane. The glass sheet heated in a continuous roller conveyor furnace to bending temperature, is picked up by a traveling suction device and transported to a curving station adjoining the furnace. In the curving station the glass sheet is deposited onto a curving device which is comprised of a curving-form frame and a curving form which form occupies the interior space of the frame. The suction device is withdrawn, and a hot gas stream is applied from above, which stream impinges on the glass sheet, whereby said sheet is forced against the curving device comprised of the curving-form frame and interior curving form. Then the glass sheet is lifted from the interior curving from by means of the curving-form frame which frame now serves as a support ring, and sheet is transported to the neighboring cooling station.

Abstract: A blow box for thermal tempering of panes of glass is disclosed. To temper different sizes of glass, the air supply to selected blow tubes or blow tube groups in a blow box having a blow nozzle field disposed to handle relatively large panes of glass is blocked in the edge areas of the blow box. In this manner, the blow nozzle field supplied with forced air is adapted to the shape and size of the glass pane to be tempered. The adaptation of the blow nozzle field to the shape and size of the glass panes takes place, for example, with the aid of a template-like slide block having an opening corresponding to the glass pane, which slide block is arranged inside the air distributing box immediately in front of the front plate provided with the nozzle pipelets and which can be exchanged for a different slide block.

Abstract: In a method of curving a glass sheet with the aid of a hot gas stream with a large cross sectional area, whereby the glass sheet is pressed against a curving form, in certain prescribed edge regions of the glass sheet in static pressure component of the flowing gas is increased by reducing the flow speed of the flow component (of the hot gas stream) traveling in the radial direction along the surface of the glass sheet, which speed reduction is accomplished by the interposition of barriers in the path of this flow component. The preferred such barriers are pressure baffles (38), which are disposed at certain selected locations on the edge of the curving form (31), said baffles being oriented perpendicularly to the terminal tangents of the forming surface (32) of the curving form (31).

Abstract: A method and apparatus are described for coating a substrate such as glass with a powder such as a compound that an be decomposed by heat. The method comprises the steps of forming a sheet of powder suspended in a gas and moving toward the substrate to be coated, homogenizing the mixture of powder and gas by creating turbulences in it, surrounding the sheet with flowing gas having the same velocity as the sheet itself, and accelerating the sheet in the direction of the substrate. This method and the apparatus which implements it are particularly useful in the manufacture of glass coated with a film such as metal oxide.

Abstract: New dyestuff salts of the formula ##STR1## wherein A denotes the radical of an azine dyestuff, R, R.sub.1 and R.sub.2 denote alkyl radicals with a total of 10-24 carbon atoms and n denotes the number 1-4. The dyestuff salts show excellent solubility in organic solvents such as alcohols, ketones and esters. Due to the excellent solubility in organic solvents, the dyestuff of the instant invention are especially suitable for dyeing solutions of polymers such as polystyrene or polyamides.

Abstract: New dyestuff salts of the formula ##EQU1## WHEREIN A denotes the radical of an anionic dyestuff, R, R.sub.1 and R.sub. 2 denote alkyl radicals with a total of 10 - 24 carbon atoms and n denotes the number 1 - 4.The dyestuff salts show excellent solubility in organic solvents such as alcohols, ketones and esters. Due to the excellent solubility in organic solvents, the dyestuffs of the instant invention are especially suitable for dyeing solutions of polymers such as polystyrene or polyamides.

Abstract: A process for the manufacture of colored shaped articles from high polymer synthetic resins, wherein water-insoluble, hydrophobic, high polymer synthetic resins in solid form, especially in the form of granules or powders, in a mixture of hydrophilic and organophilic solvents that are reciprocally soluble in one another only to a limited extent and form a two-phase system, are treated with dyestuffs or optical brighteners, the solubility of which in the organophilic portion of the two-phase system is greater than in the hydrophilic portion, the solvent is removed, the synthetic resin dried and shaped, optionally with addition of untreated high polymer fully synthetic resin, from the melt or from a solvent.

Abstract: Tetra-(alkylsulphamoyl)-copper phthalocyanines of the formula ##EQU1## WHEREIN CuPc denotes a copper phthalocyanine radical, R.sub.1, R.sub.2 and R.sub.3 denote alkyl radicals with a total of 7 - 12 C atoms, R.sub.4, R.sub.5 and R.sub.6 denote alkyl radicals with a total of 11 - 13 C atoms and n denotes 0 - 4 have a good solubility an alcohol and are particularly suitable for dyeing alcoholic solutions of film-forming polymers.
