Title: Determination of fluid volume extracted from vessel by automatic pipette in e.g. molecular biology procedure
Inventor: LUTZE KONSTANTIN
IPC: G01N35/10
Filed: 1998-03-13
Abstract: The liquid volume in the vessel V1a is detected and stored in a computer. A volume Vist is extracted in a pipette. The residual volume is also detected and stored. The volume extracted, V1ist is determined from V1a - V1e = V1ist. The difference between the that actually removed and the desired extraction V1soll is determined in the computer from V1ist - V1soll = V1diff.  The difference V1diff  is compared with a given fluid volume  iota 1 using the computer. An error message is given if  V1diff exceeds  iota 1. An Independent claim is included for the corresponding equipment. Preferred Features: Further variants and developments of the method are described, based on similar principles. A series of inequalities exemplify the relationships between volumes cited, under particular conditions.

Patent DE-19818508-A1 (DE)
Title: Communications traffic management method for telephone system
Inventor: ANGERMUELLER ROLAND
IPC: H04M1/00
Filed: 1998-04-24
Abstract: The communications traffic management method involves compressing incoming signals received from the subscriber peripheral before the signals are forwarded via a digital transmission path. The transmitted signals received are decompressed using a compression and decompression unit (TDK/TDeK) associated with each subscriber.  The compression and decompression is effected by using several different compression and decompression factors selected in dependence on a signalization received from the calling subscriber. The compression and decompression unit may be incorporated in the subscriber circuit (TSCH).

Patent DE-19848085-A1 (DE)
Title: Reflector for document scanner or copier
Inventor: BATTEN PATRICK
IPC: H04N1/04
Filed: 1998-10-19
Abstract: The lid is used as a secondary reflective surface (114). It has a reflectance range of 60 to 75 per cent which is at a level to reduce image bleed through. The reflective surface is an integral part of the lid or an attached colored surface. The reader has a lid or automatic document feeder (104) with a secondary reflective surface (114). Light rays (108) reflect off the front face (110) of a document (100) positioned face down on a transparent platen (102). Some light rays (108) pass through the document to reflect off the secondary reflective surface, pass through an image on the back (120) of the document and generate secondary reflected light rays (116). The range of reflectance of the secondary reflectance is arranged to be in the range of 60 to 75 percent to reduce bleed through, provide acceptable reduction in dynamic range and acceptable shift in perceived color.  The copier lid is used as the secondary reflective surface. The lid color provides the necessary level of reflectance. Alternatively the color of the lid is changed to provide secondary reflective surface suitable for different types of document, black for scanning/copier for OCR, white for scanning/copying transparencies, gray for scanning/copying color documents, using a slide in or snap on reflective surface.

Title: Measurement of shear or extension viscosity of fluids, especially polymers, by measuring pressure differences in two capillaries while subjecting to pure shear and shear and extension resistance
Inventor: GLEISSLE WOLFGANG
IPC: G01N11/08
Filed: 1998-10-22
Abstract: Fluid flows through a first (K1) and a second (K2) capillary in series. Fluid is merely sheared in the first capillary to determine the shear viscosity while in the second is sheared at the same or lower shear rate and also subjected to stretching flow so that the flow resistance comprises both shear and extension resistances. Flow resistance is determined by pressure measurement.  An Independent claim is made for process equipment which comprises either: a) a first capillary (K1) with a continuously enlarging cross-section, a downstream second capillary (K2) with a continuously narrowing cross-section, either connected directly together or by a connecting piece (V) and two or more pressure sensors(P1,P2) in each capillary; b) a continuously narrowing capillary cross-section followed by a continuously enlarging cross-section either connected directly or by a connecting piece and two or more pressure sensors in each capillary;c) a first part capillary with constant cross-section, a second part capillary with a lower constant cross-section, but of a different size and a transition piece with a continuously varying cross-section between them forming a second capillary with a continuously varying cross-section and two or more pressure sensors in each part capillary. Preferred Features: For separating the extension viscosity the pressure component of the shear flow resistance is obtained by subtracting the part of the pressure difference corresponding to the shear flow resistance as a result of pressure measurement at the first capillary.

Patent DE-19859779-A1 (DE)
Inventor: SCHMIDT PEER
IPC: H03K17/975
Filed: 1998-12-23
Abstract: The invention relates to a tactile sensor in which a fiber (1) is linked with an instrument transformer (4) which is configured as a capacitor in such a manner that if the free end of the fiber is touched by an object, said touch is converted to electric signals. The force acting between the object and the sensor is kept at a minimum by using soft, elastic fibers. The inventive tactile sensor is especially useful for applications in robotics since due to the appropriate arrangement of the sensor on the contact surface of the robot gripper the sensor function is independent of any forces that might occur during the manipulation of objects. Another advantage of the tactile sensor is that it allows the dynamic registration of touches, thereby making it possible to determine the relative speed between the sensor and the object and to detect gliding or slipping movements on the basis of detected vibrations.
