Abstract: A thin glass substrate, as well as a method and an apparatus are provided. The glass substrate has a glass having first and second main surfaces and elongated elevations on one of the main surfaces. The elevations rise in a normal direction, have a longitudinal extent that is greater than two times a transverse extent, and have a height, on average, that is less than 100 nm, and with a transverse extent of the elevation smaller than 40 mm. The method includes melting a glass, hot forming the glass, and adjusting a viscosity of the glass so that for the viscosity ?1 for a first stretch over a first distance of up to 1.5 m downstream of a flow rate control component and y1 indicating a second distance to a location immediately downstream the flow rate control component the equation lg ?1(y1)/dPa·s=(lg ?01/dPa·s+a1(y1)) applies.

Abstract: A formulation usable to produce plates and shaped bodies has a base slip, quartz glass particles and multicomponent glass particles that are crystallizable or at least partly crystallized. The base slip contains water as dispersion medium with a content between 30% and 50% by weight and ultrafine SiO2 particles distributed, preferably colloidally therein, with a proportion between 50% and 70% by weight. The proportion of quartz glass particles in the formulation is in the range from 40% to 70% by weight and the proportion the multicomponent glass particles in the formulation is in the range from 5% to 37% by weight. The formulation can be used in a composite material. Firing aids can be made from the composite material.

Abstract: A switching system for sequential switching of radio frequency paths is provided. The switching system comprises a plurality of inputs and a plurality of outputs, a plurality of switching elements respectively connected between the plurality of inputs and the plurality of outputs and a trigger module. In this context, multiple signal paths are defined between the plurality of inputs and the plurality of outputs corresponding to specific switch positions of the plurality of switching elements. In addition, the trigger module is adapted to generate a trigger signal in order to switch between the multiple signal paths.
