Abstract:
A device for pressing and bending glass panes comprises an upper, solid-faced bending mold and a lower frame-shaped mold. The lower frame mold is mounted horizontally traversable and serves at the same time as a support ring for transferring the bent glass pane into a cooling station. The frame-shaped mold is provided with an electrical heating resistor. In addition, a temperature sensor is disposed in the frame-shaped mold. The temperature of the frame-shaped mold can be regulated to a predetermined temperature by way of a power regulator, which is governed by the temperature sensor.
Abstract:
A production installation for the contact toughening of glass sheets comprises a horizontal furnace for heating the glass sheets, a press containing two liquid-cooled pressing plates, a feed apparatus for transferring the heated glass sheets into the press and a removal apparatus for removing the toughened glass sheets out of the press. To the lower pressing plate, a solids-transmitted sound pick-up is coupled which, if a glass sheet breaks in the press, supplies an electrical signal. From this signal, after suitable processing of the signal, the control device is triggered, and as a result thereof interrupts the process sequence.
Abstract:
A continuous furnace (straight-through furnace) for heating glass panes to their curving and/or toughening temperature is constructed as a circular furnace and comprises an annular, horizontal hot gas support bed (3). On this annular hot gas support bed (3) the glass panes are carried, each by means of a template (56) of heat-resistant metal plate, also floating on the hot gas support bed (3), in a circuit from the feed station (6) to the discharge station (7). The templates (56) are each mounted on the arms (17) of a star-type turntable (16) concentrically to the support bed (3). At the discharge station (7) the glass panes, heated to bending and/or toughening temperature, are removed from the furnace by means of a radially traversable suction plate (42) and transferred into a bending and/or toughening device disposed laterally alongside the furnace.
Abstract:
In an installation for bending glass panes, the glass panes are heated to bending temperature in a horizontal once-through furnace. At the end of the once-through furnace, they are taken over by an endless conveyor belt and are conveyed by this conveyor belt into the bending station, where they are bent together with the conveyor belt. The bent glass pane is conveyed of the conveyor belt into the succeeding cooling or tempering station. In order to support the bent glass pane over the largest possible area, an upper deflector roll for the conveyor belt, disposed at the exit end from the bending station, has a form corresponding to the transverse bend of the glass pane. A lower deflector roll, following the upper deflector roll, has a form complementary to the form of the upper deflector roll. In this way the relative changes in length of the conveyor belt caused by the upper deflector roll are compensated.

Abstract:
During a process for bending and quenching a window pane, the latter is bent to the desired shape using a forming frame. Next, by means of this same forming frame, the entire surface of both sides of the bent window pane is rapidly cooled, in a quenching station which follows the bending station, by blowing cold air using blowing boxes provided with blowing nozzles. While the entire surface is being rapidly cooled, the edge regions of the window pane which rest on the forming frame are subjected to a blast of additional cold air by the suitable supply of compressed air to the openings passing through the forming frame.
Abstract:
A vertically adjustable glass pane for automobiles, especially a door window pane, is of laminated glass consisting of two thermally toughened single glass sheets, each 1.5 to 3 mm thick, and of a thermoplastic intermediate layer. Both the glass sheets have, in their edge region, tensile stresses in the core having a value from 27 to 57 MN/m.sup.2 for a sheet thickness of 1.5 mm and 20 to 47 MN/m.sup.2 for a sheet thickness of 3 mm. In the middle area within the peripheral region the glass sheets have tensile stresses in the core which, in the case of a glass sheet of 1.5 mm thickness, have values of 25 to 42 MN/m.sup.2 and, with a glass thickness of 3 mm, values of 17.5 to 33 MN/m.sup.2. Laminated glass panes of this type have a comparatively high strength in the peripheral region and low strength in the middle area. They possess excellent properties both from a structural design standpoint and also from the standpoint of safety in case of accident.

Abstract:
A method is described for controlling the grinding of a dispersion of solid particles in a doughy-pasty mass, such as a chocolate mass, on a roller mill line having at least one preceding and one postponed roller mill (1 or 4), of which at east the postponed roller mill (4) is a roll refiner mill with a plurality of rollers (W1-W5). In this arrangement, the outlet roller gap of the preceding roller mill (1) is changed for decreasing or increasing the layer thickness of the mass in the postponed roller mill (4) having at least three rollers. Additionally and besides changing the outlet roller gap of the preceding roller mill (1) a control of the layer thickness of the postponed roller mill (4) is carried out according to a proportional-integral-differential control system. In doing so, the layer thickness can be measured on the postponed roller mill (4) within predetermined limits, with a change-over to the control system of the preceding roller mill (1) taking place upon exceeding these limits due to the difference of the actual thickness to the nominal layer thickness.
