Patent DE-19525285-A1 (DE)
Inventor: WOBUS ANNA M DR
IPC: C12Q1/6897
Filed: 1995-06-28
Abstract: The invention concerns an in vitro test procedure for the detection of chemically induced effects on embryonic development and for differentiation for the purpose of embryotoxicity/teratogenicity screening based on differentiated pluripotent embryonic stem (ES) cells from mice and rats and using embryonic germ (EG) cells obtained from primoridial germ cells. The proposed test procedure is characterised in that stable transgenic ES or EG cell clones containing tissue-specific promoters and reporter genes are selected, differentiation-dependent expression of tissue-specific genes is carried out following differentiation of ES cells in the presence of embryotoxic substances acting at specific times into different germination path derivatives; this is followed by detection of chemically induced activation, repression or modulation of tissue-specific genes which regulate embryonic development.
Patent DE-19527269-A1 (DE)
Inventor: KEINERT HELMUT
IPC: B60H1/22
Filed: 1995-07-26
Abstract: A suction pipe (2) for the combustion air of a heater, in particular a motor vehicle heater, has a variable cross-section of flow. The object of the invention is to improve the operation of the device that modifies the cross-section of flow and to allow it to be more rationally produced. In addition, it should allow the suction air to be filtered in association with said means without extending the axial length of the heater. For that purpose, the suction pipe (2) is designed as an axially closed tube with radial openings whose cross-sections may be changed by a coaxial, rotary ring (4) set on the outside of the pipe and provided with radial openings. A hood (15) may be axially drawn over the ring (4) on the housing (1) of the heater. Suction air may be filtered in said hood (15), either by centrifugation in spiral channels (18 or 19) arranged in the hood (15) or by using a ring-shaped filter through which the suction air flows in the radial direction.

Title: Vocoder coding-decoding method esp. for analogue and digital communications signals
Inventor: KLINGLER ANTONIUS DR RER NAT
IPC: H04L9/18
Filed: 1995-08-18
Abstract: The method is based on deterministically generating noise from a transmitter to a receiver via a communications channel e.g. telephone, radio link, magnetic tape. Each apparatus on the transmitter and receiver side generates identical noise signals. The first useful signal is coded for transmission, and the received signal is decoded with the same noise.  The useful signals take the form of a train of numerical values of a discrete, or continuous intervals. The noise signals are available in similar form for the interval. The useful signal and noise signal numerical values are specified. The (de)coding is carried out by addition and subtraction, respectively.

Title: Procedure for controlling colour rendering of offset printer
Inventor: FUCHS THOMAS
IPC: B41F33/00
Filed: 1996-04-27
Abstract: A procedure for controlling the colour rendering of an offset printing machine in the three basic colour channels: cyano-blue, magenta and yellow employs a combination sensor for measuring the colour densities and spectra of the printed output at preselected points over its surface. The fast response feature of the sensor system enables signals quantifying observed colour deviations wrt. a previously established ideal obtained either by direct spectral analysis or from pre-run data to be continuously monitored. Differences are converted into corrective changes to the thickness of the respective colour deposits as a result of corresponding regulation of the colour metering controls.
Patent DE-19622488-A1 (DE)
Title: Method of operating piston machine for expansion or gaseous medium at high pressure and temperature in gas plants
IPC: F01L25/04
Filed: 1996-06-05
Abstract: The method operates a piston machine which has at least one inlet valve (20). This is operated with different inlet control times for the operating medium. An outlet arrangement is effective in the region of the lower dead point of the cylinder to be effective for the expanded operating medium. The outlet arrangement has an outlet valve (30) whose opening characteristic is controllable. By means of the operation of this outlet valve (30) the cylinder chamber (1) can be emptied on movement of the piston (5) to the upper dead point. The operating medium is preferably a control medium for actuation of both the inlet and outlet valves (20,30). The chamber is then emptied into a temporary store os greater volume to reduce the pressure of the medium. The temporary store may have an overcurrent valve in the compression region.

Title: Location method for leakages in vessel by photo-acoustic signal for industrial applications
Inventor: SCHROFF GERHART
IPC: G01L21/08
Filed: 1996-06-13
Abstract: The method checks leakage points in vessels using a test chamber (2) in which the object to be tested (1) is enclosed. The chamber has an air entry point (5) with a valve (13) and is connected to a vacuum pump (12) through a further valve (11). A pressure sensor (10) is also connected. The object under examination is filled with a test gas which is readily differentiated from the atmosphere from a holder (25). Air is evacuated from the chamber to achieve a pressure difference between the test gas in the vessel and the chamber, so that after a short time the gas escapes from the vessel at any leakage point to form a cloud (22). This can be detected by a photo-acoustic process using a movable laser beam (14) and a sound sensor (20). The system is safe and practical for industrial applications.
Patent DE-19631530-A1 (DE)
Inventor: HENN DAGMAR DIPL CHEM
IPC: G01N27/30
Filed: 1996-07-23
Abstract: The invention concerns an ion-selective sensor. Sensors of this type are used in the field of chemistry and analysis in order to indicate selectively a given ion in the presence of other ions and measure its concentration, for example. The ion-selective sensor according to the invention is characterized by a contact surface between the membrane and the electrode which is substantially larger than the contact between the ion-selective membrane and analyte solution. To that end, the ion-selective membrane and the electrode interlock in the region of this contact surface, for example by means of a porous structure, and/or the contact surface of the membrane facing the analyte solution is reduced by an electrically or chemically inert layer. It is further essential that the membrane has a given thickness between the interlocking surface structures and the interface with the analyte solution, such that short-circuits cannot occur between the electrode and the analyte solution. The signals of the ion-selective sensor are then determined, for example by potentiometry or voltammetry, substantially only by the processes on the interface between the membrane (1) and analyte solution.

Filed: 1996-08-16
Abstract: The absorber is especially fitted to the bumper of a motor vehicle, and has elements (1,2) of different stiffness, whose plastic deformation can be initiated by impacts of different speeds. The elements can deform in order to absorb energy in different impact speed regions. The less stiff element (1) in one energy absorbing zone is fixed, and the stiffer element (2) can move, so that the latter is held in a parking position outside the vehicle zone, while the vehicle is travelling below a predetermined driving speed. The stiffer element is associated with the less stiff element above this speed, which is less than the impact speed which leads to deformation of the stiffer element.
