Abstract: The invention relates to a device for load limitation in a high lift system for aeroplanes, said system comprising individual segments (3, 4, 5, 6) of landing flap systems and slat flap systems, and a drive unit (7). The inventive device for load limitation comprises a control unit (23) that is connected to position sensors (15, 16, 17) and is embodied in such a way as to process signals from the position sensors and to generate a signal for limiting the supplied drive power. The invention also relates to a method for load limitation. According to said method, signals from at least two position sensors are measured; at least one reference variable is calculated from the measured signals; each reference variable is compared with a corresponding threshold value pre-determined from a maximum authorised load; and a control signal is generated for limiting the drive power, when at least one of the reference variables reaches or exceeds the threshold value.

Patent CA-2553535-A1 (CA)
Inventor: LAKSIN MIKHAIL
IPC: C09D11/10
Filed: 2005-01-14
Abstract: The present invention provides a liquid printing ink that produces high quality flexographic or gravure printing images that have excellent solvent and abrasion resistance. In addition, the printing ink of the invention has high re-solubility, even after complete drying, upon contact with the liquid vehicle of the same ink, thereby preventing clogging of the printing plate, anilox or gravure cylinders over time. These characteristics of the printing ink are obtained by preparing a hybrid ink in which conventional organic solvent and/or water-based liquid inks are mixed with energy curable monomers and/or oligomers of resins and, optionally, a photoinitiator. After drying the ink, the printed images are exposed to an actinic radiation so that highly cross-inked polymers are formed in the printed images, which become water, chemical and abrasion-resistant.
