IPC: A01D78/10
Filed: 1988-05-09
Abstract: The invention relates to a rotary tedder 1 with preferably six raking bodies 2 which are supported on the ground surface via running wheels 3. The raking bodies 2 on each side of the machine are driven by way of an input gear 8 via a respective multi-part drive shaft which is surrounded by an inner supporting tube 9, a middle supporting tube 10 and an outer supporting tube 11. The middle supporting tube 10 is connected respectively in an articulated manner to the inner supporting tube 9 via an articulated connection 12 and can be pivoted into the transport position rearwards through 90 DEG  in relation to the direction of travel A. The inner end of the middle supporting tube 10 facing the machine centre is equipped with a transverse extension 23. The transverse extension 23 carries a roller 24 which is mounted rotatably on a bearing flange 25 and which penetrates into a U-shaped edge curve 17 of a segment 16 of the inner supporting tube 9. For locking the middle supporting tube 10 in relation to the inner supporting tube 9, there are two detent bolts 28 and 29 which automatically secure the respective end positions of the roller 24 (working position or transport position). <IMAGE>

Abstract: The doctor device has a profile member pivotally mounted to a retaining member that is carried on a mount. Vertical movement of the mount causes angular displacement of the profile member thereby changing the material applicaton area disposed adjacent and upstream of the doctor. The doctor is either a doctor blade or roll doctor. In the case of a roll doctor, a receptacle is formed in the profile member and the roll doctor is magnetically retained with the receptacle. During application of a material to an application surface with the roll doctor, the roll doctor is magnetically attracted to the application surface by a second magnetic device located beneath the application surface or work surface.

Abstract: In a process for the final concentration of urea, consisting by preference of two vacuum evaporation stages operating in series in which the vapour produced containing residual NH3 and C02 and urea entrainments is separated in separators, preferably by gravity, to be condensated in systems to maintain total vacuum (vacuum systems) consisting by preference of surface condensers and steam ejectors, the product of said condensation (release condensate) being treated by preference by hydrolizing the urea and distilling the NH3 and the C02 from the condensate in a final treatment system, the improvement being characterized by the fact that the vapour containing NH3 and C02 and urea entrainments coming from the separators in the vacuum evaporation stages is brought into intimate contact with an aqueous urea solution with the ensuing passage of the urea entrained by the vapour to the solution itself before said vapour is sent to the vacuum system.

Abstract: The modulated wave whose level varies between a lower level (V1) and a higher level (V3) is characterised in that each transition of the wave (24) between the discrete continuous lower level (V1) and the discrete continuous higher level (V3) is produced by means of at least two successive similarly-directed switchings, the first switching occurring between a first extreme discrete continuous level (for example the lower level V1) and an intermediate discrete continuous level (for example the intermediate level V2), and the second switching occurring between an intermediate discrete continuous level (for example the intermediate level V2) and the second extreme discrete continuous level (for example the higher level V3). Under the modulation generated, a carrier wave (23) is compared with at least two modulating waves (for example the modulating waves 21, 22); the product wave (24) takes the lower discrete continuous level (V1) whenever the higher modulating wave (21) is below the carrier wave (23); the product wave (24) takes the intermediate discrete continuous level (V2) whenever the carrier wave (23) lies between the two modulating waves (21 and 22); and the product wave (24) takes the higher discrete continuous level (V3) whenever the lower modulating wave (22) is above the carrier wave (23). <IMAGE>

Date Mar. 9, 1989.A voice recognition system for time encoded speech (TES). The TES coded stream is divided into time frames. Each time frame is fed to a number of seeker circuits, each seeker circuit being optimized to detect an acoustic event of the voice signals, such as voiced or unvoiced events, amplitude or silence (ambient noise). Segmentation boundaries in the TES symbol stream are then determined from the acoustic events sensed as present or absent. These events are compared with stored events to determine the voice signals. By using this parallel comparison technique, comparison is made using distinct boundaries determined from the voice signal content and not by arbitrary boundaries which may contain acoustic events from, for example, more than one word in the voice signals. The implementation of the TES recognizer in low cost complimentary metal-oxide semiconductor (CMOS) technology makes this parallel comparison technique feasible at a reasonable cost.
