Title: Noise protection arrangement for railway lines
Inventor: NEUBAUER SIEGFRIED DIPL ING
IPC: E01B19/00
Filed: 1987-11-05
Abstract: The invention relates to a track installation comprising a noise protection arrangement for railway lines, the main application being in railway bridges of steel construction with an open track, in which the rails (2) or the sleepers (1) are laid directly on the steel supporting structure without interposition of ballast. Mat-like noise protection covers (3) are arranged parallel to the rails, said covers screening off the rail from the free atmosphere like a wall up to the level of the rail and absorbing the resulting noise. To deaden the structure-borne noise, further noise protection measures, such as sound-absorbing lines (4) and (6) can be arranged between the rails and the sleepers, and between the sleepers and the steel structure (5), respectively. The noise protection covers can have a box-like, in particular open, cross-section, and it is possible to walk along them, since they are formed from foamed sheet-metal sections. <IMAGE>

Title: Variable composite cork element for insulation between the rafters in a steep-pitched roof, without material waste and with an integrated wind seal
Inventor: KISTLER KLAUS
IPC: E04D13/16
Filed: 1988-02-09
Abstract: The insulating material cork, rendered variable by the invention, as heat insulation with integrated wind seal between the rafter divisions permits, for the first time, a waste-free and expert installation. By virtue of its end-side rebate configuration with the appertaining fitting piece, the composite cork element offers optimum joint overlapping without overlapping waste. The compensation panels and strips which are cut in a planar manner at the factory prevent the occurrence of a heat bridge since cutting in the thickness of the insulating material on the longitudinal sides is dispensed with. A narrowing of the element which may be necessary on the building site is achieved by cutting through the backing layer. The resulting offcuts are adhesively bonded again, on the laminated surface, with a joint-covering strip to form an element of any width. The laminated-on backing layer serves as a wind seal and, simultaneously, as a nailing batten on one side. The loose joint-covering strip is adhesively bonded, on the opposite side, with the element and then fulfils the same function as the nailing batten fitted at the factory. In contrast to the conventional processing of cork panels measuring 1000 . 500 mm which are cut to length to the respective rafter width (usually 650-750 mm) and are fastened on the rafter inner side against lathing and in the case of which a wind seal then has to be fitted over the entire surface, there results, taking into consideration the saving in labour costs ...

Patent DE-3825139-A1 (DE)
Inventor: HOETZEL GERHARD DIPL CHEM DR
IPC: G01N27/406
Filed: 1988-07-23
Abstract: Proposed is an electrochemical probe for determining the air/fuel ratio in exhaust gases from internal combustion engines, both in the fuel-low and in the fuel-rich zone. The probe has a sensor element with an electrochemical oxygen concentration cell and an oxygen pumping cell with a solid electrolyte. The sensor element is housed in a casing which can be inserted into the exhaust pipe in such a way that the electrodes of the oxygen concentration cell and the oxygen pumping cell are outside the exhaust pipe. The atmosphere can enter via openings in the casing and the exhaust gases via a diffusion gap. The sensor element is of particularly simple construction, free oxygen being available to the oxygen pumping cell both in the low and the rich lambda region. The oxygen pumping cell electrodes can be made large, thus making only relatively small current densities necessary. Overcooling of the sensor element in the region of the electrodes by cool exhaust gas (measurement gas) is avoided.
