Patent DE-19825420-A1 (DE)
Inventor: EWALD HARTMUT
IPC: A62C3/02
Filed: 1998-06-06
Abstract: The invention relates to a method and a device for extracting fumes and heat and for providing operational ventilation for traffic structures and enclosed traffic spaces. The inventive system for drawing off fumes and heat and for providing operational ventilation for traffic structures and enclosed traffic spaces does not use any pipe ventilators for extracting the fumes and builds up a vacuum throughout the entire extraction channel in order to extract the fumes. The system is characterised in that a number of reversible jet ventilators (3) are provided inside a modular smoke extraction channel (2) situated preferably beneath the tunnel roof (1) or the roof of an enclosed space. The jet ventilators are evenly distributed over the length of said channel and the channel itself has evenly distributed roof openings (2a). Said jet ventilators are able to rapidly accelerate the air or the fumes of a fire (5) on the road (8) in a particular direction in the smoke extraction channel by virtue of an impulse effect (3a).
Patent DE-19825479-A1 (DE)
Inventor: ERSOY METIN
IPC: F16H59/10
Filed: 1998-06-08
Abstract: The selection mechanism is used to electronically and/or mechanically select the gears with a pivotable gear lever (1) with a locking mechanism consisting of a pivotable blocking plate (11) actuated by a release rod (2) that can block the gear lever in a position as soon as a blocking pin engages a rocker (3). A permanent magnet (7) holds the blocking plate in the locking position. An electromagnet (8) that opposes the permanent magnet is activated to releases the blocking plate. The magnets are fixed wrt. the vehicle, e.g. mounted on the gearbox housing. A restoring spring (6) forces the blocking plate towards the locking position. An electrical or electronic sensor detects the gear lever position. An Independent claim is also included for an arrangement for implementing the method.

Also assigned is an ion current measuring device (5) for the detection of an ion current flowing after the finish of the spark. The current is determined and the spark duration resulting from it for at least one previous ignition and the control of the current takes place so that a safe ignition takes place, decaying after a specified time. The specified time is determined by the current remaining in the coil after ignition as residual energy decaying exponentially.
Patent DE-19847448-A1 (DE)
Title: Procedure for matching burner-heated heater to air-exhaust system
Inventor: BURGDORF ACHIM
IPC: F23N3/08
Filed: 1998-10-08
Abstract: The procedure uses a heater with a gas-control device working according to the heat demand and a pressure measuring point (14) which is connected to the gas-control device. It releases the gas supply only when a certain pressure value is reached in the air-exhaust system.  With first starting under established conditions of temperature and operation, the speed of the fan is slowly increased from a starting speed where the pressure value for the release of the gas supply, also for the shortest length of the air-exhaust system, is not attained, until the pressure value provided is reached. Afterwards a correction factor is evaluated from the speed where this value is reached. With the correction factor, operational characteristics can be calculated from standard characteristics according to which the gas-control device works.

Title: Web tension roll, used especially in paper or cardboard web, plastic film or metal foil manufacture or coating, contains an additional initial vacuum chamber for air boundary layer removal from the web
Inventor: HOLTMANN BRUNO
IPC: F16C13/00
Filed: 1998-10-16
Abstract: A web tension roll, containing an additional independent initial vacuum chamber (7) for air boundary layer stripping from the web, is new.  A web tension roll has a driven sleeve (1) which rotates about a stationary core and which has air passageways for reduced pressure application by means of a main vacuum chamber (8) located in the web contact region. An initial vacuum chamber (7) is positioned immediately in front of the main vacuum chamber (8) within the sleeve (1) for providing a greater reduced pressure independently of the reduced pressure in the main vacuum chamber (8). Preferred Features: The main vacuum chamber (8) is followed by a pressure chamber (9). The initial vacuum chamber (7) produces a \-0.5 (especially 1-10) kPa greater reduced pressure than the main vacuum chamber (8) and covers a smaller angular region of \-10 (especially 20-90) deg  compared with the \-30 deg  angular region of the main vacuum chamber (8). The chambers (7, 8, 9) are delimited by partition walls (3-6) fixed to a core tube (11) which has openings (16) for connection with the main vacuum chamber (8) and which has a reduced pressure line connection at one end. The tube interior is subdivided into distribution chambers (12, 13, 14) which communicate with the chambers (7, 8, 9) and which are connected to separate pressure lines at one end of the tube (11). A regulator or controller is used to adjust the reduced pressure in the initial vacuum chamber (7) in accordance with the web speed or tension.

Title: Use of on-board diagnosis apparatus for monitoring nitrogen oxide absorption catalyst regeneration, includes examination of reliability-critical components on detection of anomalies
Inventor: POTT EKKEHARD
IPC: F02D41/00
Filed: 1998-10-16
Abstract: Catalyst loading with nitrogen oxides (NOx) is determined, and compared with a maximum limit. An on-board diagnosis apparatus monitors catalyst activity. On exceeding the limit or detecting irregularity in catalyst activity, in a third stage, reliability of NOx regeneration is examined. Correct function of components relevant to reliability is examined, and/or current operation is examined through observation of predetermined parameters.  It is examined whether, meeting predetermined regeneration parameters, an NOx regeneration can be undertaken, if necessary adjusting the required NOx regeneration parameters, and introducing the NOx regeneration given permissibility of such a measure, otherwise repeating the third stage and/or if appropriate signaling a detected functional disturbance of a component relevant to reliability. NOx regeneration is carried out until a predetermined NOx regeneration level is achieved. Normal operational conditions are set and reversion to the start, or premature discontinuation or interruption of the NOx regeneration, in the case that the actual results of the reliability examination of the third stage, if necessary returning to the start or the third stage, and/or if appropriate signaling detection of a functional defect of one of the components relevant to reliability.

Title: Maritime, floating solar collectors of plastics transparent top foil and back-up foil, sandwiching photovoltaic material coated support foil
Inventor: VOLKRODT WOLFGANG
IPC: H01L31/054
