摘要:
A solid bowl helical conveyor centrifuge. The centrifuge includes a rotating drum, having a centrifuge space with a screw that can also rotate. An inlet tube for supplying a material for centrifugation into the centrifuge space, and at least one liquid discharge and at least one solids discharge, wherein the liquid discharge and/or the solid discharge is/are designed as at least one or more openings in a rotating part of the solid bowl helical conveyor centrifuge, in particular through openings in the drum wall. At least one of the openings is covered by a housing which encloses the drum of the solid bowl helical conveyor centrifuge in only some sections, between the at least one housing and the drum and/or other rotating elements of the solid bowl helical conveyor centrifuge (drum heads, hubs) at least one or more gaskets are provided.

Vibration damper, including a damping element and a pneumatic spring, wherein the damping element has a container tube, which is connected to a roll-off piston of the pneumatic spring. The roll-off piston is connected via an air suspension bellows acting as a rolling diaphragm to an external guide mounted concentrically and with freedom of axial movement with respect to the roll-off piston, the air suspension bellows and the roll-over piston forming the boundaries of a space filled with pressurized gas. The container tube is prepared for the installation of the roll-off piston by a non-cutting procedure suitable for mass production, wherein a length of tubing having the diameter of the container tube is mounted on a mandrel and clamped at both ends so that its length cannot change, and a pair of flow-turning/rotary-swaging rolls is pressed against the tubing and advanced toward each other to form an area of squeezed material. The rolls are then moved radially while being advanced axially over the area of squeezed material to form a first contour having a bevel, a cylindrical surface, and an axial stop for fitting the roll-off piston to the container tube.

A damping element has a container tube which is connected to a rolling tube of an air spring, the rolling tube being connected via a spring bellows acting as a rolling bellows to an outer tube which is arranged concentrically and such that it can move axially with respect to the rolling tube, the spring bellows and the rolling tube bounding a gas chamber provided with a gas filling under pressure. The rolling tube is sealed off with respect to the container tube by an O ring in a groove in the container tube, while, at another point on the container tube, projections are arranged as a stop for a front end of the rolling tube in order to dissipate the axial component of the gas pressure acting on said rolling tube. The assembly of the rolling tube on the container tube and the associated sealing by means of the O ring are achieved simply in a cost-effective manner by pushing the tubes together, the position of the tubes in relation to each other resulting automatically as a result of the projections.

The invention relates to a sensor device for capturing data when carrying out first aid measures for reanimating a person affected by a cardiac arrest. The sensor device is exactly positioned on the chest of the patient by means of a positioning-aid apparatus (5) and affixed by means of a fastening means (2). The thorax compressions, i.e., the pressing-in depth and compression frequency, are detectable by means of a motion sensor. A data-transfer interface allows communication, e.g. wireless communication, with a mobile terminal.
摘要:
An apparatus for distributing fluids in an exhaust system of an internal combustion engine. The apparatus includes an injection device, wherein a combination of a plurality of individual measures for achieving a uniform mixing of the fluids with the exhaust gas and a complete vaporizing of the fluids in the exhaust gas is provided. The individual measure comprises at least one of at least one swirl-generating device and at least one mixing apparatus. The individual measure also includes at least one catalyst. The individual measure further includes an injection nozzle of the injection device which is arranged at a predefined spacing from a wall of the exhaust tract.
摘要:
For controlling a target system, such as a gas or wind turbine or another technical system, a pool of control policies is used. The pool of control policies including a plurality of control policies and weights for weighting each control policy of the plurality of control policies are received. The plurality of control policies is weighted by the weights to provide a weighted aggregated control policy. The target system is controlled using the weighted aggregated control policy, and performance data relating to a performance of the controlled target system is received. The weights are adjusted based on the received performance data to improve the performance of the controlled target system. The plurality of control policies is reweighted by the adjusted weights to adjust the weighted aggregated control policy.
