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.

The invention relates to a hydrostatic drive (1) in an open circuit. The hydrostatic drive (1) comprises a hydraulic pump (2) and a hydraulic motor (3). The hydraulic pump (2) and the hydraulic motor (3) are connected to one another via a feed line (4). In addition, the hydrostatic drive (1) comprises a storage element (18) for storing pressure energy. A first valve device (17) which is arranged downstream of the hydraulic motor (3) alternately connects the downstream connection (9) of the hydraulic motor (3) to a tank volume (15) or to the storage element (18).
摘要:
A method for producing high-purity, large-volume monocrystals that are especially radiation-resistant and have low intrinsic birefringence. From a melt of crystalline raw material, with controlled cooling and solidification, a crystal is generated. As the crystalline raw material, shards and/or waste from already-grown crystals is used, and the re-used raw material 1) upon visual observation in daylight has no color; and 2) upon illumination with a white-light lamp in a darkroom a) has no or at maximum a just barely perceivable reddish and/or bluish fluorescence; and b) has no or at maximum a just barely perceivable diffuse scattering; and c) has no or only slight discrete scattering of at maximum two visually perceivable scattering centers per dm3. In this way, crystals can be obtained which after tempering have a BSDF value of

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.

A device is provided for regulating the thickness of rolling stock in a roller stand. The device includes a control device that controls the roller adjustment of the roller stand as a function of the deviation between a reference thickness value (h*) and an estimated value (h') for the thickness of the rolling stock exiting from the roller stand; a model simulating the rolling process in the roller stand, the model calculating the estimated value (h') on the basis of roller technology parameters and measured values; a thickness measurement device that measures the thickness of the rolling stock after its exit from the roller stand with a measurement delay (T.sub.L) providing a measured thickness value (h.sub.L); a delay device for delaying the estimated value (h') determined by the model by at least approximately the amount of the measurement delay (T.sub.L); a correction device generating a correction value (k) as a function of a deviation (.DELTA.h.sub.L) between the measured thickness value (h.sub.L) and a delayed estimated value (h'.sub.L), the correction value (k) correcting the estimated value (h') provided by the model; a controllable switching device enabling the generation of the correction value (k) to be stopped in time periods during which the thickness measurement device provides no measured thickness values (h.sub.L) or no usable measured thickness values; and a holding device making available during the time periods the correction value (k) last generated for correction of the estimated value (h') provided by the model prior to the generation of the correction value (k) being stopped.
摘要:
This invention involves the field of tactile control of electronic devices using a sensor that transduces both air pressure and device positional orientation into a set of digitally encoded commands. The invention involves using as input the physical action taken on a musical instrument and generating control information using that input.

A mounting frame for a switchgear cabinet or a rack includes mounting pieces which are arranged, as corner pieces, in the four corner sections of a rectangle or square that extends in an x-y plane, the mounting pieces being produced in a respective shaping process and having outer first and second mounting faces which extend in the x direction and in the y direction at a right angle thereto and which extend in a space direction z at a right angle to the x-y plane, and are provided with hollow spaces which are at least partially surrounded by wall parts and/or bores that are oriented in the z direction. The mounting frame further includes intermediate elements which extend between the mounting pieces in the x direction and in the y direction and the end sections of which are fastened to the mounting pieces. The mounting pieces have wall sections which extend in parallel to the x-y plane, thus making assembly easier.

A monitoring device and method are provided for monitoring a vacuum toilet, as well as a personal transport vehicle, in particular an aircraft, which uses a monitoring device for vacuum toilets. The monitoring device has a position detector for detecting the position of a toilet lid, a mechanical latching device and a flushing control unit. The latching device is designed to latch the toilet lid in an open position based on the weight of a person acting on a toilet seat. The flushing control unit is further designed to control the flushing operation based on the toilet lid position, and to block the flushing operation upon detection of the toilet lid in the open position. This makes it possible to improve both the comfort and hygienic conditions for the toilet user while using the vacuum toilet.
