Patent DE-4126025-A1 (DE)
Title: Fail=safe control system for vehicle throttle - has two sensors for control setting, with failure detection and isolation of faulty sensor
Inventor: GOSSER MARTIN DIPL ING
IPC: F02B77/08
Filed: 1991-08-06
Abstract: The throttle setting is monitored by two sensors (12,32) whose outputs are compared by a logic circuit (40) Programmed max. and min. values for the control setting are compared with the sensor outputs to determine if any sensor is faulty. If one sensor is faulty then the vehicle is controlled via the remaining sensor. On failure detection, the system provides two reference signal levels for the faulty sensor to enable the control to continue. An additonal fail-safe control reduces the maximum fuel input during failure operation. ADVANTAGE - Vehicle can continue to be driven to repair centre at normal speed if sensor fails.

Title: Determining optical activity of non-doubly refracting media - passing light through measurement paths of different lengths containing two polarising elements with relative polarisation angle dependent on desired measurement range
Inventor: LEHMANN HARTMUT
IPC: G01N21/85
Filed: 1991-10-05
Abstract: The method of determining the optical activity involves coupling light into a measurement path containing the medium under investigation. The light is polarised at a point in the measurement path and passed to at least one measurement channel and a reference channel. The relative polarisation angle of the polarising elements varies with the desired measurement range. The length of the measurement path is changed at least once to find the change in polarisation state of the light passing through it. The degree of optical activity is derived from a relationship of channel intensities for the different path lengths using a scale factor and the damping channel of one channel. Optical fibres are used to register the measurement signal. USE/ADVANTAGE - For chemical analysis using polarimeter. Method is implemented using miniaturised, low-cost arrangement and eliminates problematic operation under adverse conditions.

Filed: 1991-11-23
Abstract: A travelling bracket crane with a rigid jib or a jib which can be slewed in the horizontal plane is proposed, in each case of a smaller overall height and overall width in comparison with known cranes. The invention is distinguished in that all the cantilever moments acting in the vertical plane are introduced into the crane runway support or supports (1) via a vertical force couple by means of vertical or slanted crane running wheels (7, 10) arranged on the crane individually or in pairs, offset transversely with respect to the crane travelling direction. In this arrangement the crane running wheels (7, 10) are supported on the crane runway support or supports (1) or their projecting parts, on the one hand on the underside and on the other hand on the upper side. The cranes can be used with the same spatial relationships very diversely in different operating planes and immediately adjacent operating areas. In addition, retrofitting is possible, even in cases where hall dimensions are restricted. <IMAGE>

Title: Method for the qualitative and quantitative optical detection of molecules, biomolecules and microorganisms
Inventor: SEEGER STEFAN DR
IPC: G01N21/64
Filed: 1993-03-05
Abstract: The present invention relates to a method for the optical detection of molecules, biomolecules and microorganisms. Most methods, which use receptor molecules as the recognition molecule for highly selective binding of analytes, are multi-step methods, for example enzyme immunoassay tests. The development of one-step methods, that is to say sensors, is intended in this case especially to reduce the time which is necessary for a test. Various optical sensors have therefore also been described, such as those which use the evanescent wave on the surface of an optical waveguide for selective excitation of the molecules bound on the surface. If a laser diode which emits light in the red or near infrared wavelength region is used for the exitation, it is possible, in combination with dye molecules whose absorption range overlaps with the laser wavelength, to reduce the background fluorescence, considerably to reduce the constructional cost, and simultaneously to use the evanescent wave when a time-saving one-step test is constructed.

Title: Method and device for the on-line processing of paper sheets
Inventor: HEYER KLAUS
IPC: B65H39/02
Filed: 1993-05-03
Abstract: The method and the device for on-line processing of paper sheets, in particular for the production of brochures having several pages, operates with a collating device (1) in which the individual paper sheets are collated to form an imbricated stream. This imbricated stream runs into a collecting station (4) in which only the collection of one set takes place. When this collection has been completed, the set is fed to further processing to be folded and/or stapled. Hence, the collecting station (4) is only used for the collection. The residence time and thus the waiting time is very short. The further processing station (5) undertakes the other further processing operations, such as stapling and/or folding, according to the type of the end product. As a whole, the processing time is considerably increased by means of the interposition of the collecting station (4). <IMAGE>
