20130217141 | METHOD FOR DETERMINING AN ANALYTE IN AN AUTOMATED MANNER - A method for determining an analyte of a liquid sample in a cuvette includes providing a cuvette, a reagent, a barcode, an icon on the cuvette and a liquid analysis device comprising a photometer, a rotation device, a camera, a calibration data memory storing first calibration data, and an input device which manually inputs second calibration data. The cuvette is inserted into the liquid analysis device and is rotated to align the icon with the camera. The icon is read with the camera and the icon read compared with an icon model stored in the liquid analysis device to determine whether it corresponds thereto. The liquid sample is subjected to photometry based on the first calibration data if the icon read corresponds to the icon model. If not, the input apparatus is activated and the liquid sample is subjected to photometry on the basis of the second calibration data. | 08-22-2013 |

20120167673 | WATER ANALYZER COMPRISING A PNEUMATICALLY DRIVEN MULTI-CHAMBER PERISTALTIC PUMP - A water analysis device with a pneumatically actuated multi-chamber peristaltic pump includes a base plate comprising a plurality of proximally open pump chambers disposed on a proximal side of the base plate. A pump membrane disposed on the proximal side of the base plate is configured to close the pump chambers. A cover plate is disposed on the pump membrane comprising a respective pneumatic actuator channel in a region of each of the pump chambers. The pneumatic actuator channel is configured to connect to an overpressure source which actuates the pump membrane. A connection channel formed as a groove on a distal side of the base plate is disposed between two of the pump chambers. A separate groove cover is disposed on the distal side of the base plate in a region of the groove. The separate groove cover closes a distal opening side of the groove. | 07-05-2012 |
20120195799 | PROCESS ANALYZER - A process analyzer for detection of an analyte in a liquid under analysis includes a base module and an exchangeable cartridge module. The exchangeable cartridge module comprises a sample taking device comprising a membrane configured to obtain a sample from the liquid under analysis. A first pump mechanism is configured to pump the sample away from the sample taking device. A second pump mechanism is configured to introduce a reagent into the sample. A measuring section is configured to perform a quantitative detection of the analyte in the sample. A degassing device is arranged downstream of the first pump mechanism and the second pump mechanism. The degassing device is configured to degas the sample. | 08-02-2012 |

20110284787 | PRE-CLOSING APPARATUS OF A MACHINE - A pipe-closing apparatus of a machine which is suitable for processing foodstuff mixtures, contains a throttling valve arranged in a pipeline and has a closing element configured with respect to the pipeline with two sealing sections. The apparatus further has an activation apparatus for transferring the closing element into an open or closed position and vice versa. Accordingly, the closing element is formed by a three-dimensional rotationally symmetrical body which has a passage, wherein, in the open position of the closing element, at least the inlet and outlet openings of the passage are aligned with the pipeline, and, in the closed position, the passage is subjected to a pressure for the ingress of compressed air. The pipe-closing apparatus is suitable equally for use in a machine for producing a milk-containing ice cream and for processing and/or preparing, for example, caramels, jams, sweets, crème bavaroise, milk creams and confectioner's creams. | 11-24-2011 |
