Abstract: A sensor (18) for measuring the rheology of materials is provided, comprising a deformable beam (20) simply supported at two locations (21 and 22). The beam has supported and unsupported portions, with the unsupported portion (28) extending beyond the supported portion. A strain gauge (23) is attached to the supported portion of the deformable beam (20), and measures the induced strain on the beam when the unsupported portion (28) is deflected by a moving material.

Abstract: A sleeve unit for converting a liquid sample into a sample gas and for mixing the sample gas and a carrier gas into a uniform gas mixture and delivering the gas mixture to the inlet end of a capillary tube of a gas chromatograph comprises a tubular liner having a bore, an inlet expansion chamber in the bore for changing a liquid sample into a sample gas, a mixing chamber in the bore next to the inlet chamber, a spiral core baffle inside the mixing chamber for thoroughly mixing the sample gas and the carrier gas into a uniform gas mixture by guiding the sample gas and the carrier gas into a spiral path around the spiral core baffle between the baffle and the liner, and an outlet chamber next to the mixing chamber for delivering the thoroughly mixed sample and carrier gases to an inlet end of a capillary tube of a gas chromatograph.

Abstract: An apparatus for determining crosswind effects on motor vehicles has arranged on the vehicle two differential pressure sensors which are each connected via two conduits to two openings at the outside of the vehicle and record the pressure difference which occurs between the connected conduits or the associated openings. From this, it is possible for the angle of incidence and the dynamic pressure of the crosswind to be determined by a computer.

Abstract: A magnetic head device comprising a magnetic core member made from a magnetic material having a positive magnetostriction constant and having confronting pole pieces separated by a non-magnetic material to form a transducing gap. A coil is wound around the magnetic core member so that a read signal can be read out from the coil, and a d.c. bias magnetic field is generated in the magnetic core member when a read signal is read out from the coil so that distortion of the read signal is suppressed.

Abstract: The present invention relates to a portable gas cylinder safety containment system removably and operably incorporated with a portable, self powered, toxic gas monitoring system, and both removably attached to a delivery cart system, to provide real time monitoring of the delivery cart contents while in transit. This system is designed particularly for the safe transport between storage and work areas of toxic and hazardous gases used in various research, laboratory and production process, such as those in the semiconductor and microcircuit industries.
