Abstract: Disclosed are systems and methods for an assessment framework that operates to dynamically generate customized surveys for recipient-respondent pairs. The customized surveys can have curated questions dynamically selected and/or provided from recipients based on, but not limited to, which recipients a respondent should give feedback to, how many questions the respondent should answer, and which questions in particular, the respondent should answer. The disclosed framework can automatically and dynamically customize surveys for individual respondents, and/or sets of respondents, according to the selected questions included therein and/or from which recipients they are sent from (or on their behalf).

Abstract: A pressurised filtration vessel, for example in cylindrical form, may include a filter element comprising a plurality of filtration membrane modules, e.g., ultrafiltration membrane modules; a distributor connected to an inlet for distributing an input fluid to the filter element; and a collector connected to an outlet for collecting an output fluid from the filter element. The filter element may be located between the distributor and the collector.

Abstract: The invention relates to an injector unit and a method for the control of the injection process into the cavities of injection moulding tools. The novel solution permits the injection of thin-walled injection moulding pieces (76, 77), with both electrically- and hydraulically-driven injector screws. One of the most important features thereof is the active selection of the opening time of the locking system at an optimal pressure in the compression chamber, preferably in the region of the upper half of the compression. The volumetric transfer flow is thus significantly improved in thin-walled injection moulding pieces (76, 77). Above all the melting pressure in the tool, the flow speed and the useful flow path in the cavities are increased.

Abstract: The invention relates to a method and device for the production of injection moulded parts, especially preforms, in an injection molding method. The raw material and the additives are fed to a plasticizing worm (4) which injects pressurized plastic melt into the cavities of an injection mould (7,8) and the injection molded parts are removed from the moulds after cooling has occurred. According to the invention, the additives, especially AA blockers or coloring, are added directly to the worm cylinder in liquid form in a dosed manner after the raw material has been inputted. The invention relates more specifically to the injection molding of preforms for the production of PET bottles. One advantage of the invention is that it enables the acetaldehyde content to be reduced by 50%, the dosing time can also be reduced significantly and said dosing can be stabilized in a significant manner.
