Title: Acquiring and storing video images in continuous memory in vehicle for documenting traffic conditions - involves overwriting oldest image in store with latest image depending on defined criteria
Inventor: EIBENSTEIN ROLF DIPL ING
IPC: H04N5/781
Filed: 1992-06-29
Abstract: The current latest image overwrites the oldest image in the memory and storage is halted according to certain criteria, e.g. acceleration and non-linear or abnormal deviations.

Title: Overload protection for chain drives, esp. for chain-driven coal cutter - involves comparing actual and desired revolution rates to control overload coupling switching
Inventor: BREIMHORST ARNO
IPC: G01L5/00
Filed: 1992-10-29
Abstract: A measurement sensor (11) which contactlessly senses a measurement rotary part driven by the chain drive's electric drive motor (1) sends measurement pulses to an electronic evaluation and control unit (6). The control unit periodically determines the torque-dependent revolution rate of the chain drive or the instantaneous changes in the revolution rate. The measurement sensor is a Hall effect semiconductor. The power consumed by the electric motor during each measurement interval is measured simultaneously with the periodic revolution rate measurements. The actual torque during the measurement interval is derived from the sensor measurement pulses. The computer produces a switching signal for the overload coupling according to the comparison result. USE/ADVANTAGE - Esp. for coal cutter chain drive overload protection. Almost delay-free load removal is achieved when overload coupling is switched. Reliable protection.

Title: Door-stay device
Inventor: KOEHLER WALTER DR
IPC: E05C17/56
Filed: 1993-02-25
Abstract: The invention relates to a door-stay device for a door with a sliding-arm door closer. The staying action is effected by means of an electromagnetic retaining device with an electromagnet 15, 16, 17 which is integrated in the guide rail 3 of the sliding arm 2. The retaining device exhibits a movable latching lug 25 which is displaced into the movement path of the sliding arm under the action of the spring 30. In the case of the known door-stay devices of this type, the anchor plate which interacts with the electromagnet is arranged on that side of the electromagnet which is directed away from the movement path of the sliding arm. The invention now provides that, in the case of the door-stay device, the anchor plate 21 is arranged between the latching lug 25 and the electromagnet 15, 16, 17. The anchor plate 21 is, then, arranged on that side of the electromagnet which is directed towards the movement path of the sliding arm 2. <IMAGE>

Title: Arrangement and method for extending the measuring range of Nomarski microscopes
Inventor: SCHULZ UWE
IPC: G02B21/00
Filed: 1993-04-08
Abstract: The invention relates to an arrangement and a method for extending the measuring range of Nomarski microscopes, in which polarised illuminating light is split into two wave fronts by at least one element (Nomarksi prism 4) which produces a shear component, the wave fronts are then passed through an imaging optical element such that illuminating light impinges on the specimen (sample) (7), is reflected from there, the imaging optical element and the element which produces the shear component being passed through and, at the same time, the two reflected wave fronts being superposed and made to interfere by means of an analyser (2). The invention is characterised in that via rotation of the specimen (7) in an x-y plane about a y axis about an angular amount  DELTA PSI  and the carrying out of in each case one measurement in the different angular positions  PSI 1 and  PSI 2 light (intensities I1, I2) is registered by a receiver (matrix receiver 1) and the inclination angles  PSI (x, y) of the surface elements are determined, from the signals, over the extended inclination angle range (e.g.: n-4, ..., n0, ..., n+4). By means of the invention, inclination angles  PSI  of surface elements can be determined unambiguously in a relatively large interval, this corresponding to an extension of the measuring range of the Nomarski microscope by, for example, the factor 5. <IMAGE>
