Abstract: An abrasive cutting blade is provided to achieve high-quality surface finishes at high feed rates. The blade is fabricated by electroplating fine abrasive onto a steel cathode disc to form a first layer, followed by electroplating a second layer of coarser abrasive onto the first layer. A third layer of fine abrasive is then electroplated onto the second layer. The resulting composite is then removed from the cathode disc to form a multi-grit, multi-layer, hub-less blade.
Abstract: An unwrought refractory composition, in particular for producing glass furnace hearths, includes a base mixture comprising in wt. %: 1 to 6% of a hydraulic cement, and 94 to 99% of particles of at least a refractory material mainly consisting of alumina (Al2O3), zirconia (ZrO2) and silica (SiO2), the fraction of the particles of the base mixture having a size less than 40 ?m being distributed in wt. % relative to the weight of the base mixture, as follows: fraction<0.5 ?m: ?4%; fraction<2 ?m: ?5%; fraction<10 ?m: ?16%; fraction<40 ?m: 29–45%, the refractory composition further comprising, in wt. % relative to the weight of the base mixture: 0.02 to 0.08% of organic fibers, and 0.075 to 1% of a surfactant.

Abstract: A low-emissivity multilayer system, capable of being bent and prestressed, for glazing panes, with silver as functional layer, comprises a sacrificial metal layer of Ti or an alloy of Ti and Zn and/or Al placed above the silver layer, antireflection dielectric layers and an oxide, nitride or oxynitride covering layer. The sacrificial metal layer contains chemically bonded hydrogen. An optionally Al- and/or In-doped ZnO layer is adjacent to the sacrificial metal layer. The covering layer consists of a titanium compound. Multilayer systems of this type can be manufactured relatively inexpensively and have a high hardness and a high chemical resistance. Their color parameters are very reproducible, even in the case of a heat treatment at high temperature.

Abstract: A plant for the manufacture of mats formed of continuous yarns originating from bobbins and thrown onto a conveyor belt. The plant includes at least one bobbin supported on a spindle, a guide for guiding a fiber bundle leaving the bobbin, a mechanism for pulling the fiber bundle, and a mechanism for throwing the yarns that make up the fiber bundle onto the conveyor belt. The guide for guiding, the mechanism for pulling, and the mechanism for throwing the fiber bundle are fixed, located in the continuation of one another and at one and a same level. The throwing mechanism includes a swinging arm for throwing the yarn transversely to the conveyor belt and the guide is arranged such that the fiber bundle is paid out from the bobbin from the outside.

Abstract: A method for fabrication of a vehicle drop glass, with a transparent, in particular curved, pane, on the extremity of which a support part is to be attached, which cooperates with a drive and/or guide device for heightwise movement of the pane. In the method the pane is oriented and attached at plural predetermined points of its surface in a device adapted to its shape, a curable plastic material is deposited on the pane with aid of at least one tool in the region of the assembly with the support part and is fashioned, in a fixed position in the space inside the device, into a fashioned part which, after its assembly with the pane, defines the position of the support part in relation to the predetermined points. The plastic material is then cured. A window pane can be produced according to the method.
Abstract: A window including deliberate rupture zones. The window is obtained by a method whereby the glass is subjected to local overheating of the structure using a high-energy beam penetrating the glass, deliberate rupture zones are produced by sequentially guiding the beam in a predetermined path along the preferred path for the window to break along, and by sequentially focusing the beam both along the predetermined path and at various depths relative to the surface of the window. The sequential focusing at various penetration depths follows a line that is inclined and/or curved relative to the normal to the surface of the glass so that a weakened structure is created in the window to obtain rupture behavior of the window that differs according to the direction in which the influence leading to rupture acts.
Abstract: A method for deposition of titania, and titania-containing, thin films by CVD, using an atmospheric pressure glow discharge plasma as a major source of reaction, which leads to film properties, and film growth rates, normally only achievable (by atmospheric pressure CVD) with significantly higher substrate temperatures.
