摘要:
A finger lever (1) is configured for the simultaneous loading of three identically operating gas exchange valves. To simplify the manufacture of a hydraulic medium supply of its hydraulic clearance compensation elements (4) resting on valve stem ends and to prevent unnecessary losses of hydraulic medium, the invention proposes the arrangement of only one central passage (12) in the finger lever (1) for supplying all the clearance compensation elements (4). This passage (12) extends near a central transverse plane of the finger lever (1) and opens into a cross-passage (10) in the form of a through-bore to the individual clearance compensation elements (4).

A rocker arm (1) or finger lever for a valve drive of an internal combustion engine is provided in which a guide bushing (7) is press-fit in a receptacle hole (2). The guide bushing (7) has a bore (9) in which an outer part (4) of a hydraulic play compensation component (3) is guided in a sliding manner. The guide bushing (7) has a radially inwardly directed projection (10) which holds a shoulder formed by a diameter reduction of the outer part (4) from behind or meshes in a groove of the outer part (4). This arrangement allows the hydraulic play compensation component (3) to be secured from loss using the press-fit guide bushing (7).

A disposable container is provided for mixing media. The container has at least one closable opening for introducing and/or removing media and has sensor mounts at spaced apart locations on the wall of the container. Each sensor mount has a front surface facing into the container and a rear surface sealed against the wall of the container. Sensors are embedded in the respective sensor mounts at positions adjacent the front surfaces. The sensors measure at least one specified parameter of the media at spaced apart locations in the container. The seals between the rear surfaces of the sensor mounts and the wall of the container ensure sterility for the media in the container.
摘要:
A method is provided for mixing media in a container. The method includes introducing a first media into the container and then introducing a second media into the container while mixing the media to form a mixture. The method continues by measuring the values of two parameters of the mixture at spaced apart locations in the container. The introduction of the second media into the container may be interrupted based on a comparison of the measured values to a preselected intended value.
摘要:
A dosing system and a method for dosing a medium, having a dosing control unit (4), at least one exchangeable container (2) containing a medium to be dosed, and a dosing valve (3, 3′) that can be connected to the container (2), wherein at least one part of the dosing valve (3, 3′) that comes into contact with the medium is designed as an exchangeable system component (7, 10) and has a machine-readable code for identification purposes, wherein at least one container (2), as an exchangeable system component (2), has a machine-readable code for identification purposes, wherein the exchangeable parts (2, 7, 10, 19) that come into contact with the medium are designed as disposable parts, and wherein the dosing control unit (4) is connected with a communication unit (5) to read the codes, and wherein the communication unit (5) has a unique read connection (22) to each exchangeable system component (2, 7, 10, 19) or its code.
摘要:
Container and method for the mixing of media, in particular as a disposable container, which has at least one closable opening for the introduction and/or removal of the media and has a first sensor for measurement of at least one parameter of the mixture, in which at least one second sensor for measurement of the same parameter is arranged at a distance from the first sensor.
摘要:
An apparatus for the elimination of dusts from gases, with a filter arrangement, which is flown through by a loaded volume flow, and a cyclone which is arranged upstream to the filter arrangement, wherein a collector funnel below the filter arrangement forms the cover of the cyclone, wherein a branch stub forming the dust outlet opening of the collector funnel forms the dip pipe of the cyclone and an outlet opening of the cyclone is connected to a dust collector tank arranged under it.
摘要:
The invention discloses an apparatus for removing samples or introducing fluids from/into system(s) having flexible walls. A sampler/fluid dispenser (3) is fixed on the outside with a connecting area (4) of its base (5) on a sample removal region/fluid dispensing region (6) of the flexible wall (2) and, in its interior, has a severing element (8). At least the severing element (8) can be pushed forward in the direction of the sample removal region/fluid dispensing region (6) in order to remove the samples and in order to introduce fluids, in such a way that the wall (2) can be perforated within the sample removal region/fluid dispensing region (6). The system (1) comprises containers, bags or tubes for filling, mixing, transporting, storage of media, such as biological liquids, sera, buffers, ultra-pure water and can be used as biological reactors or cell culture vessels in the pharmaceutical and biotechnical industry.
摘要:
A display for on-site visualization of conditions of an automated process is disclosed. It comprises a display controller which at least temporarily provides a state indication signal representing a constellation of states of at least two process data signals. At least one of the two process data signals is derived from a signal generated externally to the field device. The field device has a display element which responds to a change in the state indication signal with a significant change in its appearance, thus signaling the constellation of the states of the two process data signals in a visually perceptible manner. Therefore, the field device is particularly suited for on-site monitoring of entire plants or sections thereof by operating personnel.
