Patent DE-4130099-A1 (DE)
Inventor: SCHUBERT AXEL DR
IPC: G01N27/04
Filed: 1991-09-11
Abstract: 2.1 In a known gas-measuring apparatus, the test gas sample to be examined is sucked through a combustion chamber by a test gas delivery pump, a portion of the combustible fractions of the sample being combusted at a preheated measuring sensor. In order to monitor the volume flow, whether or not there is flow through the combustion chamber, additional measuring devices are required which involve complicated circuitry. The object of the novel gas measuring apparatus is to provide simple and cost-effective monitoring, the use of the measuring elements already available for gas-measuring being incorporated. 2.2 In order to monitor the volume flow (14), a monitoring circuit (V2, V3, V4 and 8) integrated in the measuring circuit of the measuring bridge (1) is provided, which monitoring circuit comprises amplifiers (V2, V3 and V4) which in each case separately measure the voltage signals of the reaction heat sensor (2) and the thermal conductivity sensor (3) as well as a temperature sensor (8). The amplifiers are connected to a signal processing system (9, 10, 11). Owing to the volume flow arising, the heated sensors (3, 4) cool down, as a result of which they undergo a resistance reduction which can be measured as a measure for the volume flow present. <IMAGE>

Title: Direct position determination system e.g. for agricultural vehicle - uses constantly rotating directional transmitter and calculates time differences of signals received at set positions
Inventor: ANGERER JOHANN
IPC: G01S5/02
Filed: 1991-12-13
Abstract: The system directly determines the position of vehicles moving along the ground in all three coordinates.

Title: Method for mfr. of hollow profile out of metal strip - utilises strip bent back on itself to form joint edges for high-frequency welding
Inventor: WELSER WOLFGANG ING
IPC: B21C37/08
Filed: 1991-12-18
Abstract: The method concerns mfr. of a hollow profile out of a metal strip by means of rolling and high-frequency welding of the opposing joint edges. The profile constitutes a closed hollow body with at least one stand-off flange. The profile (1) is formed from a single metal strip (2) so that the opposing joint edges (5a, 5b) of the hollow body (3) become two-layered through bending back of the strip on itself, essentially through 180 deg. The opposing edges are welded, with the stand-off flange (4, 7) adjoining the bent-back part of the strip as its integral part. The bent-back part of the strip (2) pref. follows the outer circumference of the hollow body (3) and terminates as a stand-off flange (4, 7). The wall of the hollow body (3) - with the exception of its joint edges (5a, 5b) - is single-layered as is the flange (4, 7). USE/ADVANTAGE - E.g. for mfr. of tubes with longitudinal flanges. It allows high-frequency welding to be used for such tubes formed from a particularly thin strip.

Title: Conductive distributor for solid electrolyte fuel cell - consists of open network formed by depositing reinforcing and conductive layers on organic matrix and firing this
Inventor: KOBAYASHI SHOZO
IPC: H01M8/02
Filed: 1992-02-20
Abstract: The distributor for use in a solid electrolyte fuel-cell consists of a porous matrix (20), pref. a soft polyurethane foam without cell-walls, on which a reinforcing layer (22), pref. of Y stabilised ZrO2, is deposited and a conductive layer (24). The conductive layer (24) pref. has a main constituent of (La,Sr)(Mn,Cr)O3 or (La,Sr)MnO3. The distributor pref. is made in the form of a disk or a rectangle. Pref. a suspension is formed by mixing the reinforcement material together with a solvent in a mill, to wet-grind the material. At the end a binder is added. A similar technique is used to make a suspension of conductive material, using appropriate materials. The reinforcing suspension is then used to impregnate the matrix, if necessary several times, until the required thickness has been obtd. The excess suspension is then removed. Then the suspension with conductive material is used to impregnate the matrix until the required thickness has been obtained, and the excess suspension removed. USE/ADVANTAGE - The matrix, after firing, has an open structure which offers very little resistance to the gas-flow. The conductivity is very high, as well as the mechanical strength. The material has almost identical coefft. of thermal expansion (CTE) as current material made without the reinforcing material, but a very much higher strength. The porosity is in the order of 90%.
