摘要:
A method for extracting bulk material from a container which is open at the top by means of a suction apparatus which comprises at least one suction pipe (10) and one or more scrapers (12), with the suction apparatus being laid from above onto the surface of the bulk material in the container and bulk material being sucked away through the at least one suction pipe (10), wherein, during a repeated relative rotational movement between the scraper (12) and the surface of the bulk material in the container, bulk material is conveyed along the one or more scrapers (12) in the direction of the at least one suction pipe (10).
摘要:
The invention relates to a method for producing hollow molded bodies in a tool support, comprising the following steps: (i) the initial components used for producing the molded body are poured into a mold (iv) that is provided with a core (v) defining the hollow space of the molded body; (ii) the mold (iv) is opened, die molded body being retained by the core (v); (iii) the molded body is removed from the core (v) by removing the molded body from the core (v) outside the mold (iv).
摘要:
An apparatus and a method for predicting cognitive performance of an individual based on factors including preferably sleep history and the time of day. The method facilitates the creation of predicted cognitive preformance curves that allow an individual to set his/her sleep times to produce higher levels of cognitive performance. The method also facilitates the reconstruction of past cognitive performance levels based on sleep history.
摘要:
The invention relates to a process for preparing mixtures of polyols for further processing to give polyurethanes, comprising at least one graft polyol, which comprises carrying out the mixing of the polyols between the preparation of the polyols and the preparation of the polyurethanes, by means of a continuous mixing process.
