Title: Vertically adjustable side grazing for motor vehicles
Inventor: KRAEMLING FRANZ
IPC: C03B27/00
Filed: 1991-08-19
Granted: 1999-06-15
Abstract: A vertically adjustable composite motor vehicle side glazing, particularly a door window glazing, is made from composite glass including two 1.5 to 3.5 mm thick thermally tempered individual glazings with a thermoplastic intermediate layer. Each individual glazing has in the marginal area tensile stresses in the core, which in the case of a glazing thickness of 2 mm amount to 54 to 76 MN/m2 and for a glazing thickness of 3 mm amount to 46.7 to 71.2 MN/m2. In the central zone within the marginal area the individual glazings have tensile stresses in the core, which in the case of a glazing thickness of 2 mm amount to 38 to 67 MN/m2, while for a glazing thickness of 3 mm amount to 33 to 60 MN/m2. Such composite glazings have high strength in the marginal area and a low strength in the central zone. Therefore they have excellent characteristics both from the static standpoint and from that of accident safety.

Inventor: KIM KYUNG-RYUL
IPC: D06P3/32
Filed: 1992-10-21
Granted: 1995-12-20
Abstract: The raw inner cattle hide is initially bleached after it has been separated from an outer skin, processed to a predetermined thickness and cut to form a product. A pattern is then drawn on the hide using a liquid adhesive agent as a resist. When the resist has hardened so it does not flow, the hide is then soaked with a water pigment in a first coloring pigment tank. A second pattern is then drawn on the colored hide and the hide soaked in a second coloring pigment tank; the pigment does not adhere to either of the patterns. Drying the hide allows the resist to be removed and the colored pattern is then protected. Coloring and patterning of raw inner cattle hide are performed prior to manufacturing into wristlets, hair clips, baskets, waste paper basket, etc..

Abstract: The invention relates to a process for making self-assembled films, with applications in electronics industry. According to the invention, the process consists in that, in a first stage, a graphite substrate is subjected to oxidation with a sulphonitric mixture and an oxidation accelerator, to result in the graphite oxide which is, in the second stage, subjected to ultrasonication in dipolar aprotic solvents for 1...5h, to result in graphene oxide which, during the third stage, is reduced with sodium borohydride, after which, in the fourth stage, the resulting graphene oxide sol is heated to the temperature of 50° C, for 1...3 h, to finally result in self-assembled films of controlled thickness in the range of 0.1...2 μm.
