摘要:
The thin flat glass substrate, especially for display engineering, has a thickness of less than 1.5 mm, a length of at least 1800 mm, a width of at least 1800 mm and a difference between a smallest thickness and largest thickness of less than 50 μm. The float glass process for making the improved flat glass substrate provides flags (9) in the molten metal bath in the hot-spread region on both sides of the forming glass sheet, to minimize the variation in thickness of the thin flat glass substrate formed by the process.

摘要:
A roller-equipped annealing lehr for flat glass, having a roller conveyor inside a lehr housing, with heating units arranged in pairs above and below the roller conveyor, in rows situated one after another and extending transversely to the feed direction. Temperature regulators are provided with predetermined desired values and actual temperature values that are measured in a position-dependent fashion. In order to achieve a desired stable temperature distribution and to prevent stresses in the flat glass, a feedback loop arrangement for at least one pair of heating units situated at a particular position in the row, presets as a control variable the heating output required to predetermine the temperature distribution in the region of this position as a predetermined portion of a heating output, which is calculated based on at least one actual temperature value measured at a different position in the row.

The invention relates to a roller-equipped annealing lehr for flat glass (1), having a roller conveyor, which is accommodated inside a lehr housing, and having heating units (2) that are arranged in pairs above and below the roller conveyor, in rows situated one after another and extending transversely to the feed direction, and are associated with temperature regulators provided with actual temperature values that are measured in a position-dependent fashion and predetermined associated desired values. In order to achieve the desired temperature distribution in a long-lasting fashion and to prevent stresses in the flat glass, the present invention provides a feedback loop arrangement (3, 4, 5), which, for at least one pair of heating units (2) situated at a particular position in the row, presets as a control variable the heating output required to predetermine the temperature distribution in the region of this position as a predetermined portion of a heating output, which is calculated based on at least one actual temperature value measured at a different position in the row. The invention can be used to particular advantage for the treatment of thin, preferably floated, flat glasses.

The glass is suitable for three dimensional precision molding and suitable for toughening, wherein after toughening, the glass has a center tension smaller than 50 Mpa, a surface compressive stress of 600-1200 Mpa, and a bending strength of up to 500 MPa. The glass also has a transition point lower than 550° C.
摘要:
Conventional airbag apparatuses have a very large volume for offering the greatest possible protection for the passenger, and therefore block the driver's view of the traffic situation and preclude further steering actions. Additionally, the passenger is endangered if he is in an atypical sitting position. Multi-stage airbag systems permit an adaptation of the degree of deployment to the size and/or position of the passenger, but are very complicated and slow. Proposed is a passenger-protection apparatus having a first airbag for a first stage of deployment, and a second airbag for a second stage of deployment, which occurs after and independently of the first, with the shape of the first airbag and the quantity of gas supplied to it being determined such that, when filled with this quantity of gas, the first airbag has a collision zone that corresponds to the diameter of the steering wheel, and has a short expansion length in the direction of the passenger, in relation to the distance between the collision zone and the passenger. A second airbag, which can be deployed independently, laterally surrounds the first airbag, partially or preferably completely, in the manner of a hose in the filled state, and compresses the first airbag, so the expansion length of the first airbag increases. Whereas the first airbag is deployed early and independently of the position of the passenger, the second airbag can be filled afterward with different quantities of gas when a second acceleration threshold is exceeded, as a function of the position and/or size of the passenger, by a controllable gas source, which can preferably be deployed in stages, thereby establishing the shape of the two airbags and the deformation of the first airbag.
