20100083739 | Chromatography System with Fluid Intake Management - A liquid chromatograph includes a mobile phase supplying apparatus including a plurality of liquid-feeding pumps to feed mobile phases, a plurality of liquid-feeding flow paths, a mixer to mix the mobile phases by merging the liquid-feeding flow paths, at least one control device to control driving of each of the liquid-feeding pumps based on flow rates for the respective liquid-feeding flow paths, a plurality of flow rate measuring sections provided downstream of the liquid feeding pump in each liquid-feeding flow path, the plurality of actual flow rate measuring sections configured to measure an actual flow rate and to detect a back-flow in the corresponding liquid-feeding flow path, and a plurality of actual flow rate computing sections configured to compute an actual flow rate in the corresponding liquid feeding flow path. The liquid chromatograph also includes a sample injecting section downstream of the mobile phase supplying apparatus where the mobile phases are supplied from the mobile phase supplying apparatus, a separating column for provided downstream of the sample injecting section for separating an injected sample into its constituents, and a detector for detecting each of the separated constituents. When one of the plurality of actual flow rate measuring sections detects a back-flow in the corresponding liquid-feeding flow path, the corresponding actual flow-rate computing section computes an actual back-flow rate and outputs a signal to the corresponding control device which controls the corresponding liquid-feeding pump so as to cancel the back-flow based on the computed actual flow rate. | 04-08-2010 |
20110259451 | Chromatography System with Fluid Intake Management - A method of determining a leak in a pumping system includes determining a metered flow rate of a fluid through a first channel, determining a measured flow rate within the channel, and identifying an amount of a leak in the pumping system as the difference between the metered flow rate and the measured flow rate. | 10-27-2011 |

20110308325 | APPARATUS FOR GENERATING SMALL FLOW RATES IN A CHANNEL - A fluidic apparatus for a sample separation system includes a fluid inlet path for supplying a fluid, an inlet sensor adapted for measuring a flow rate of the fluid in the fluid inlet path, a splitting point arranged downstream of the fluid inlet path and adapted for splitting the fluid into a first path and into a second path, and a second path sensor adapted for measuring a flow rate of a part of the fluid conducted into the second path. | 12-22-2011 |

20090074543 | Method and Device for Transporting and Processing Multiple Items - A method and a device transports and processes multiple items, in particular postal consignments. Each item passes through a first processing installation and then at least one second processing installation. The first processing installation measures in each case a processing attribute and two values which two predefined features assume for the item, and generates a data record for the item. Data records for items that the second processing installation subjects to a predefined treatment are selected. The second processing installation measures at a first time point the value which the first feature assumes and later the value of the other feature. It searches for a selected data record and uses the feature value measured initially. When it finds such a data record, it subjects the item concerned to the predefined treatment. | 03-19-2009 |

20080237017 | EASY-TO-CLEAN KEYPAD DEVICE - Keypad devices have become commonplace in everyday life. They are part of our everyday life, in the form of pocket calculators, telephones, remote control devices, and cellular phones. Cleaning these keypad devices is problematic, since they have a large number of actuatable keys, due to the functions to be performed. As a mechanical interface in the keypad device, each key is a critical weak point in terms of maintaining a tight seal. An easy-to-clean keypad device, in particular an emergency call device, has a main body, an electronic assembly—which includes circuit elements and is installed in main body—a closing shell and keys, which are installed in closing shell and are designed to mechanically actuate the circuit elements. Closing shell with installed keys is a first preinstalled assembly, and main body with installed electronic assembly is a second preinstalled assembly. The first and second preinstalled assemblies are interconnected such that they may be separated. | 10-02-2008 |
