Title: Gas and temp. sensor arrangement - for temp. independent determination of esp. oxygen@ partial pressure
Inventor: GERBLINGER JOSEF DIPL PHYS
IPC: G01N33/00
Filed: 1992-03-30
Abstract: An arrangement for determining the partial pressure of a designated gas in a gas mixt. includes: (i) a gas sensor (G) of material with a conductivity of ohmic resistance which varies with the gas partial pressure and temp.; and (ii) a temp. sensor (T) of material which is exposed to the same ambient conditions as the gas sensor and which has a conductivity or ohmic resistance varying with temp. in the same way as the gas sensor material when the temp. sensor is exposed to a predetermined fixed partial pressure of the designated gas at different temps. The measurement signal (S2) of the temp. sensor is subtracted from that (S1) of the gas sensor to obtain a temp.-independent evaluation signal proportional to the gas partial pressure to be determined. Also claimed is use of the sensor arrangement for respiration monitoring, in which the periodic oxygen partial pressure changes of exhaled air are determined and irregularities of the period are evaluated. The gas sensor (G) consists of TiO2, CeO2 or esp. SrTiO3 and the temp. sensor (T) consists of SrZrO3. The sensors are applied onto a substrate by sputtering or screen printing. USE/ADVANTAGE - The arrangement is useful for detecting oxygen partial pressures in gas mixts. from combustion processes (esp. automobile exhaust gases) or for respiration monitoring. It allows direct, temp.-independent partial pressure determination rapidly and with high accuracy

Title: Linear antenna array having an omnidirectional characteristic
Inventor: HEYDE WOLFGANG
IPC: H01Q9/40
Filed: 1993-03-18
Abstract: The omnidirectional aerial for frequencies in the UHF band is constructed from dipole groups arranged in vertical levels. The radiating elements, and preferably the supply line network as well, are coated onto one or both sides of a flexible plastic film (7). The film is wound in layers around the metallic supporting tube (1) of the antenna such that every winding layer (8, 9, 10, 18), which comprises 360 DEG , is preferably fitted with one electrical functional group of the antenna structure. Cylindrical spacer shells (3, 4, 5, 17) made of dielectric material having a low  epsilon r are inserted between the individual winding layers of the conductor film (7) for spacing. The invention reduces the material, the parts and technological outlay for fixed-position transmitting and receiving antennas, for example for mobile cellular radio networks - and, above all, the mass as well - and enables greater variability and cost-effective further optimisation of the RF parameters. <IMAGE>

Abstract: The invention relates to a welding head for a stud-welding device, with a piston (8) displaceably arranged in the axial direction in a pressure chamber (4). With a peripheral area (8c) of an area of larger diameter (8a), the piston (8) divides the inner area of the pressure chamber (4) into a chamber volume (4a) located in front of the area (8a) and a chamber volume (4b) located behind the area (8a) and essentially seals these chamber volumes (4a, 4b) from one another, in which arrangement a pressure medium can be fed to at least one of the chamber volumes (4a, 4b) via an opening in the pressure chamber (4). The piston is led out of the pressure chamber (4) in an essentially pressure-tight manner at least on one side and interacts with a stud holder (18) for a stud (3) to be welded. The piston can be deflected from a centre position by a predetermined displacement against the force of a restoring element. <IMAGE>
