    摘要: A pressure sensor for measuring a pressure difference between a pressure being measured and the ambient atmospheric pressure surrounding the pressure sensor, including a platform and a membrane loadable with a pressure being measured. The membrane is secured at its edge to the platform, with a pressure chamber thus being formed between the platform and the measuring membrane. The pressure chamber communicates over a reference air path with the atmosphere, with the reference air path being a winding path.

    摘要: This active brazing preferably serves to braze (join) ((aluminum-)oxide-)ceramic parts or single crystals or metal parts or to braze (join) ((aluminum-)oxide-)ceramic parts to single crystals or ((aluminum-)oxide-)ceramic parts or single crystals to metal parts. In addition to the zirconium-nickel alloy, which is composed of 70 atom % to 85 atom % zirconium and 15 atom % to 30 atom % nickel, it contains titanium. In an apparatus for fabricating a foil (6) from this ternary active-brazing alloy by melt spinning which has a uniform thickness and two surfaces that are as smooth as possible, the alloy, after being melted by high-frequency heating in a cylindrical crucible (1) made completely of a high-temperature-resistant and highly thermally conductive nonmetallic material, particularly of high-density graphite or of boron nitride, is forced through an opening (3) in the bottom of the crucible onto a metal drum (5) of high thermal conductivity rotating at a high circumferential speed, on which the liquid alloy solidifies at a cooling rate on the order of 10.sup.3 .degree. to 10.sup.6 .degree. C./s. A product made using this ternary active brazing is a pressure sensor (10 ) having a substrate (12) and a diaphragm (11) of ceramic, particularly alumina ceramic, preferably with a purity of 96 wt. %, which are thermally joined around the periphery in a defined spaced relationship (d) and parallel to each other by means of the active brazing , e.g., by means of a preform (20) made therefrom, thus forming a chamber (13) .

    摘要: A velocity such as wind velocity is measured based on a Doppler shift of a backscattered or returned laser signal. The Doppler shift of the backscattered beam is determined from a change in the polarization state or intensity shift of the received or backscattered signal after it has passed through a polarization-dispersive element (PD) and through a polarization analyzer (PA). The electrical signals (I1 and I2) generated from two partial beams provided by the polarization analyzer (PA) represent an the intensity shift. The signals are processed in a computer and the resulting information is displayed, for example.

    摘要: Cereal is combined with more than 50% fruit or vegetable foods by weight for obtaining a nutritional fluid food composition. The cereal component is based upon an enzymatically hydrolyzed cereal in liquid form. The composition does not require including sugar as a further component of the composition and is comprised of at least 10% cereal by weight based on dry matter and in addition to the fruits or vegetables and enzymatically hydrolyzed cereal in liquid form, includes oatmeal, water and oil for providing a desired fat content.
