Abstract: A separator device for separating liquid from solids of matter includes a drive shaft rotatable about a drive axis of rotation and extending in an axial direction between an upstream shaft end and a downstream shaft end. A screw conveyor connected to the drive shaft is adapted to convey the matter in a conveying direction from an upstream inlet to an outlet downstream from the inlet. The screw conveyor at least partially encloses the drive shaft and a screening device encloses the screw conveyor. The screening device is adapted to separate liquid from the solids of the matter and to convey the matter in the conveying direction. A drive unit is coupled to the downstream shaft end of the drive shaft. The drive shaft is mechanically coupled to the drive unit such that the drive shaft is in the for of a tension rod.

Abstract: Systems and methods consistent with certain embodiments of the invention relate to optimization of hierarchy screen refreshes in a graphical user interface. According to one exemplary embodiment, a method for refreshing a graphical user interface that includes a navigation hierarchy is disclosed. The method comprises storing a first representation of the navigation hierarchy at a front end system and a second representation of the navigation hierarchy at a back end system, the second representation being a reduced version of the first representation. The method receives a user interaction with the graphical user interface and sends user inputs to the back end system if the user interaction triggers an event. The method determines at the back end system an updated representation of the navigation hierarchy based on the user inputs, without requesting the first representation of the navigation hierarchy from the front end system.
