摘要:
A method and system for handling simple materials in, for example, mixing plants, for enabling a central analysis of the samples. The samples are automatically and frequently taken from outlets of silos and are brought unwrapped and successively to an automatic near infrared reflection analyzing station through an pneumatic conveyor system with substantially common type sections between the station and the single samples. Sample portions which are larger than required for analysis are removed so as to counteract the risk of contamination of the samples, with the large sample portions then being returned to the silos of origin through another pneumatic conveyor system.

The present invention relates to a process for liquefaction and saccharification of polysaccharide containing biomasses, having a relatively high dry matter content. The present invention combines enzymatic hydrolysis with a type of mixing relying on the principle of gravity ensuring that the biomasses are subjected to mechanical forces, primarily shear and tear forces. Furthermore, the present invention relates to the further utilisation of such processed biomasses, e.g. for subsequent fermentation into bio-ethanol, bio-gas, specialty carbohydrates for food and fees as well as carbon feedstock for processing into plastics and chemicals.
摘要:
A method of TIG welding with alternating current with a welding apparatus (10) which is arranged in such a manner that the polarity of the welding current is controlled by an electronic control circuit (20), which is also arranged so that it continuously registers whether or not the arc is lit, and in that the welding apparatus comprises a controllable inverter (16) and means for re-igniting the arc in the positive period, and arranged so that the length of the positive period is shortened if the arc is not re-ignited in the positive period. The invention also relates to a welding apparatus which can be equipped with a logical circuit or a programmable circuit which instantly ensures that the positive welding period is shortened if the arc is not re-ignited in this period.
