The invention relates to a drive (1) having an energy recovery function. The drive having an energy recovery function comprises a hydrostatic piston machine (9) and at least one storage element (13) which is connected to said hydrostatic piston machine. Said hydrostatic piston machine (9) and the at least one storage element (13) are connected together by means of a storage line. Said storage line is divided into a first storage line section (11) and into a second storage line section (12) by a throttle value unit (15). Said throttle valve unit (15) comprises a control pressure valve unit (16) and a built-in valve (17). The control pressure valve unit (16) produces a control pressure which acts upon the built-in valve (17).

Systems and techniques for managing services and applications of a client system, such as an enterprise computer system, reduce the operational workload and optimize daily support process by deliverying embedded services in client system with direct connection of services into a back-end system so that back-end system processes can analyze client system information and provide detailed reports and analyses and with continuous (or regular) data exchange between client system and backend system to ensure efficient client system software processes. The embedded services can include support, operation, change and deploy, and plan and optimize services. The output of at least one of these services can be pushed to and displayed in a graphical user interface. A fact sheet provided with he graphical user interface contains on one page all the information that is needed to clearly show who is responsible for handling information technology problems, incidents, tasks, and service requests.
摘要:
The invention relates to a hydrostatic drive. The hydrostatic drive (1) includes a hydraulic pump (3) and a hydraulic motor (7). The hydraulic pump (3) may be connected by way of a first working line (5) to a first working line connection (8) of the hydraulic motor (7) and by way of a second working line (6) to a second working line connection (9) of the hydraulic motor (7). Furthermore, the hydrostatic drive (1) includes a first storage means (40) for storing pressure energy and a second storage means (41). For recovery of the pressure energy stored in the first storage means, the latter may be connected, at least for one direction of conveying, to a first or second working line (5, 6) which is on the suction side in relation to the hydraulic pump (3) in this direction of conveying.

摘要:
The device for production of a monocrystalline or a multicrystalline material blank, especially a silicon multicrystalline blank, using the VGF method has a crucible with a rectangular or square cross section. A flat heating device, especially a jacket heater, which generates an inhomogeneous temperature profile, is arranged around the crucible. This temperature profile corresponds to the temperature gradient formed in the center of the crucible. The heat output of the flat heating device decreases from the top to the bottom end of the crucible. The flat heating device includes parallel heating webs, which extend in a meandering course. The heat outputs from the heating webs differ according to their different conductor cross sections. To avoid local overheating in corner areas of the crucible, constrictions of the cross sections of the heating webs are provided at inversion zones of their meandering course.
