Title: Optical surface scanning apparatus
Inventor: ROES DIETER PROF DR
IPC: G06K7/10
Filed: 1994-01-25
Abstract: The apparatus includes a laser light source from which a light beam is emitted to a movable optical fibre. The beam has an almost point-shaped cross-section and moves over the surface by a mechanical drive. A focussing optical system is spatially fixed in relation to the surface being scanned. The beam from the source is fed to a flexible light conductor, e.g. an optical fibre.  One end of the fibre is fixed relative to the source. The other end is mechanically movable in an orthogonal plane relative to the optical axis of the focussing system. The fibre is arranged in a region between the single and double values of the optical system focal length. The distance of the fibre beam aperture from the system is selected depending on its distance to the surface being so small that through movement of the fibre the whole surface can be scanned with the light point.

Title: Process and device for producing coke
Inventor: REERINK W
IPC: C10B57/04
Filed: 1978-11-10
Abstract: The process for producing coke, in particular furnace coke, uses considerable amounts of lean or relatively lean caking coal which is submitted to compaction so as to obtain pressed substances; these pressed substances are used on their own or mixed with additional material as charge in a coke furnace for the coking. The coal (A) is submitted during compaction to forces acting upon different directions (D, T) in order to create shearing and/or rotating stress. This causes the mutual fixing of the coal particles thus giving highly resistant pressed material with a high degree of conservation. During compaction, heat can be brought to the material. A device for application of this process comprises a matrix and an element which makes the material pass through the channels of the matrix. These channels have different diameters and can also have different lengths.

Title: Barrier post for parking lots and passageways
Inventor: QUANTE HEINRICH
IPC: E01F9/615
Filed: 1985-12-10
Abstract: The folding barrier post (1) is equipped with a drive (10) which causes it to pivot around a hinge axis (2), and can be switched by a receiver which matches a portable transmitter, whereby the drive (10) and receiver are preferably arranged in the hollow post (1) on a mounting rail. Preferably, the drive (10) actuates a capstan (11) for a cable (13) which is fed around a fixed deflection roller (14), the other end (15) of which is secured in the ground in front of the post (1) in the direction of folding. The post (1) which folds down in the approach direction is preferably arranged to slope in the said direction, or is provided at its tops with a weight which effects an overhang in the direction of approach, in such a way that the post, on being released, folds down as a result of its own weight; a hydraulic jack with a hydropneumatic accumulator can reduce the energy consumption. The drive (10), which is preferably designed as an electric motor, can, owing to the presence of solar cells arranged on the outer side of the post (1), be provided with intermediate switching of an energy accumulator, as well as with a flashing light. A heating system for the drive (10) ensures the operation of the latter in the event of unfavourable weather conditions. The receiver can be designed as a selenium cell which responds only to a headlight flash or other suitable light source; alternatively, such a selenium cell can switch the receiver in response to the transmitter; in addition, a switching circuit board or induction loop which responds to the parked or arriving vehicle can immediately switch the drive and/or receiver.
