Title: Hot or cold air blower for vehicle - has motor speed dependent on vehicle speed and uses microprocessor for temp. control
Inventor: RABL HELMUT DIPL ING
IPC: B60H1/00
Filed: 1980-02-21
Abstract: The air blower has its speed controlled by the speed of the vehicla. The blower motor (G) has its speed regulated by a signal produced by a pulse generator measuring the distance travelled by the vehicle. The pulse generator has a sensor (SI) producing the control signal without being mechanically connected between the rotating part and the electronic circuitry. The sensor is a wheel sensor with reed contacts, which are located near the output of the gearing and the drive wheels. Alternatively the sensor may be inductive -- e.g a Hall effect device. A converter (W) converts the frequency of the pulse generator into a voltage (T) or into a pulse train whose pulse width depends on frequency. A microprocessor may be used to control the blower motor depending on the temp. outside the vehicle, the temp. of the cooling water and the temp. inside the vehicle. The converter is actuated by a manual device (H).

Title: Image evaluation method with optoelectronic preprocessing
Inventor: MUEHLENFELD EIKE PROF DR ING
IPC: G06V30/144
Filed: 1981-03-13
Abstract: The information which is relevant for image analysis and image classification is essentially contained in the image contours. Conventional methods scan the entire image using a television camera in a fixed raster and transmit the entire image information for processing into a computer. The contour sensor described in the application carries out a two-dimensional correlation with a narrow gap, and calculates the tangential component of the correlation gradient (Figure 1) during rotation of the gap. The gap detects very many adjacent pixels for every possible contour direction, and thus largely suppresses interference points in the image and the local noise caused by inhomogeneities in optoelectronic transducers. Contour detection in the presence of various image defects and a strongly structured background have been demonstrated with the aid of statistical analysis of metallurgical structures, the control of manufacturing robots in tracing object edges, automatic weld examination, and the evaluation of aerial photographs. <IMAGE>

Title: Recoverable shuttering which is intended for the anchoring region of a prestressing member in a concrete structural part
IPC: E04C5/12
Filed: 1981-06-15
Abstract: A recoverable shaped blockout part (9) in the form of a pot which is intended for the anchoring region of a prestressing member in a concrete structural part, having a central through-passage for the prestressing member, consists of an elastically deformable material such as rubber, plastic or the like. The spindle tube (14) passes through the shaped part (9) in a central through-passage (10), which spindle tube is connected, at one end, to the base of the shaped part (9) and passes, with its other end, through the shuttering (7) on which the shaped part (9) rests. By means of a nut (22) screwed onto the spindle tube (14), the shaped part (9) can be pressed against the shuttering (7) and axially compressed during the introduction and hardening of the concrete. This results in a transverse deformation of the wall (21), which, once the concrete has hardened, facilitates the release of the shaped part (9) from the concrete structural part and, by forming an undercut, improves the hold of the filling mortar in the cavity thus formed. <IMAGE>
