Patent DE-3438117-A1 (DE)
Title: Process and device for producing veneered profiles
Inventor: KOEHLER ALBERT DIPL ING DR
IPC: B29C63/04
Filed: 1984-10-18
Abstract: In the production of veneered profiles, the profiles (2) and the veneers (3) are fed separately to the covering machine, where a heated adhesive (4) is applied to the veneer and the profile and veneer are adhesively bonded together by pressure rollers (1). After adhesive bonding, although the adhesive is cooled off, it is still sufficiently hot for the veneer to detach itself again if stresses have occurred as a result of the pressing on. This is avoided by cooling with water. The profiles must then be dried before further processing. In order to avoid this interruption to production, the cooling is carried out with liquid nitrogen by spraying it onto the veneered profile. It is especially advantageous if the cooling is carried out, at least partly, while the pressing on of the veneer is still in progress or directly thereafter. To this end the pressure rollers are provided with a felt covering (10) which is impregnated with nitrogen. In the case of complicated profiles, cooling blocks which correspond to the profile cross-section and have a felt insert (16) can also be used. The felt inserts are impregnated with nitrogen and the cooling blocks are brought into contact with the profile directly downstream of the pressure rollers. <IMAGE>

Title: Sawing apparatus for the cutting-to-size of profiled strips or the like
Inventor: BERGLER OTTO
IPC: B23D45/02
Filed: 1985-12-13
Abstract: A sawing apparatus for the cutting-to-size of profiled strips or the like according to Patent ... (P 3422101.8) is described. This sawing apparatus has two circular saw blades which can be set at an angle to one another, are each driven by saw units and are staggered in the feed direction on a slide displaceable relative to a work-supporting table provided with a stop. In the initial position of the slide, the work-supporting table with the stop and the cutting area lies between both saw blades. One saw blade therefore acts on the workpiece from above and the other saw blade acts on the workpiece from below through the work-supporting table. At least one of the two saw units is pivotably mounted on the slide about an axis which runs parallel to the slide guide and coincides with the intersection line of the two saw blades. This design enables the slide to be guided in a non-pivotable and reliable manner so that, on the one hand, heavy saw units can be provided on the slide and, on the other hand, angular cuts can also be made in workpieces without a pivoting action of the slide being necessary in each case for the second cut. Both saw units are preferably pivotably mounted on the slide and are designed in such a way that certain preselectable angles can be set and also firmly locked between the saw blades and between the saw blades and the stop.

Title: Method and device for asynchronous motor acceleration of an asynchronous generator
Inventor: WICK ALBERT DR
IPC: H02P1/26
Filed: 1987-08-19
Abstract: In the generator mode, the stator winding of the asynchronous generator is connected to a supply network N, while a converter (DU) supplies the rotor windings with a nominal rotor current vector (iL(L)<*>) which is predetermined in a rotor-oriented manner. A phase-difference measurement device (PD) forms the difference angle between the stator voltage vector (uS(S)) and the rotor axis (wL(S)), with whose aid a nominal rotor current vector (iL(F)<*>), which is predetermined in a field-oriented manner, is converted into the rotor-oriented nominal rotor current vector. For motor acceleration, the stator winding is isolated from the network (N) and is short-circuited. In consequence, the synchronous generator becomes an asynchronous machine whose rotor-oriented field angle (wF(L)) is calculated in an asynchronous machine model from the components of the nominal rotor current vector (iL(F)<*>) which is predetermined in a field-oriented manner. For acceleration, the nominal values for the field-parallel rotor current vector are predetermined in proportion to a nominal flux value (F<*>) and a nominal torque value (M<*>). However, the stator winding can also be connected in series with the rotor winding, with the phase being reversed, for motor acceleration, and the asynchronous generator can be accelerated as a double-synchronous asynchronous motor. <IMAGE>
