Title: Method and device for measuring the fluorescence decay time of a fluorescing substance
Inventor: FEHRENBACH GUSTAV W DIPL PHYS
IPC: G01K11/32
Filed: 1987-09-24
Abstract: The subject-matter of the invention is a method and a device for measuring the fluorescence decay time of the radiation of a fluorescing substance whose fluorescence decay time depends on at least one physical quantity (variable). The fluorescence radiation is fed back onto the output radiation in a control loop whose controlled variable is a measure of the physical quantity. In this case, the fluorescence radiation is fed to a photoelectric receiver whose output signals are fed, after phase-sensitive rectification and integration, to a voltage-controlled oscillator. The fluorescence radiation is rectified alternately in a phase-sensitive fashion only in the decay phase. The total times of the rectification sections, which are of different lengths in the two directions, are the same. The alternatingly rectified signals are integrated. <IMAGE>

Patent DE-3739649-A1 (DE)
Inventor: MUNDT WOLFGANG DR
IPC: C12N5/00
Filed: 1987-11-23
Abstract: In order to obtain cell cultures in relatively large quantity, it is necessary to detach the cultures in each case from the microcarriers and transfer them to unoccupied microcarriers. To date this has been carried out intermittently by adding trypsin, which causes detachment of the cells, to a container with colonised microcarriers. A high percentage of the cells detaches rather rapidly and thus remains a long time in the trypsin solution, which has an adverse effect on these cells. 
<??>In the process, the trypsin solution is passed in a continuous flow process through the container and thus through the microcarriers. Detached cells are therefore immediately flushed out of the container, and the trypsin solution is inactivated and/or separated out after leaving the container. 
<??>The process can be used for growing cell cultures on microcarriers.

Title: Clamping device for clamping a workpiece
Inventor: SEUSER HANS ULRICH
IPC: B25B5/16
Filed: 1988-01-29
Abstract: To apply the vertically acting clamping force, known clamping devices engage on the horizontal surface of the workpiece. This has the disadvantage that this surface cannot be worked or can be worked only partially. Furthermore, these devices are unwieldy and are composed of a relatively large number of parts, thereby making handleability difficult. The novel clamping device is to eliminate these disadvantages. For this purpose, there is formed at the front end of a clamping bar (1) an opening (6), the shape of which enables the pivoting of a screw (7) guided and held therein. The screw (7) is received in a holding element (8) which has a bolt (9) running perpendicularly to the axis of the screw (7). The present clamping device is employed particularly advantageously in the machining of heavy workpieces, in particular in the case of hollow shaped blocks. <IMAGE>

Title: Means for avoiding total freezing of the ground structure of artificially laid vegetation surfaces at minus temperatures
IPC: A01G9/26
Filed: 1988-02-16
Abstract: At least one heating element which can be supplied with electric current is arranged in the vegetation layer (8) of an artificial ground structure which comprises at least a drainage layer (5) and a vegetation layer (8) and is intended for cultivating greenery of different types, said current supply being controlled by a temperature regulator in dependence on the temperature which has been established in the vegetation layer (8), by a temperature sensor (19), in comparison with an adjustable minimum desired value. Consequently, complete freezing of the ground structure, in particular of the vegetation layer, can be avoided, and the intake of moisture and nutrients by plants via their roots is also ensured at minus temperatures (Fig. 1). <IMAGE>

Title: Control slide with lever actuation
Inventor: BRUNNER RUDOLF
IPC: F15B13/04
Filed: 1988-04-13
Abstract: In control slides with lever actuation and a threaded connection (8, 20) coupling the actuating lever to the slide piston, there is the risk of the slide piston turning in the housing bore (5) during operation despite the springs (25) normally loading the slide piston. This is disadvantageous when the flow passages in the piston slide are not arranged in a rotationally symmetric manner. In the novel control slide, the problem of the anti-rotation locking of the slide piston is solved in a simple and effective manner in terms of assembly. For the anti-rotation locking of the slide piston, an extension (13) eccentric to the longitudinal axis (12) of the slide piston is provided between the slide piston (6) and an abutment (24) non-rotatable in the direction of rotation about the longitudinal axis (12) of the slide piston. The extension (13) is fastened to one part and engages in a displaceable manner in a sliding guide of the other part. The extension does not impair the displacement of the slide piston. But it does prevent the slide piston from rotating in the housing bore. <IMAGE>

Patent DE-3824339-A1 (DE)
Title: Method for identifying and feeding telephone terminals
Inventor: STELZER MANFRED
IPC: H04M19/08
Filed: 1988-07-18
Abstract: The invention relates to a method for identifying and feeding telephone terminals which are supplied with power via the subscriber line. An identification current flows even during operation via a current sink, and a voltage regulator dependent on the charge of a buffer capacitor referred to the activation and de-activation supplies equipment components connected downstream. If the feed voltage via the subscriber line is too low, the voltage regulator may be continually activated and de-activated depending on the capacitor charge. The object is to prevent this. This is achieved by increasing the identification current after the voltage regulator has been de-activated so that the voltage regulator is re-activated only when the feed voltage is so high that, despite the high identification current, the capacitor is adequately charged. The identification current is thus reduced once more, thereby providing adequate feed for the individual terminal components. This method is used, for example, in line concentrator systems. <IMAGE>

Title: Sewing machine with an over-transport device
Inventor: KLUNDT KURT
IPC: D05B29/00
Filed: 1989-01-27
Abstract: In the stroke-adjusting system according to the main application, the gear connection between the over-transport foot and the press foot has a three-position controller for the automatic adaptation of the height position of the over-transport system. This is preferably a hydraulic controller, the hydraulic cylinder of which is subdivided into two chambers by its adjusting piston. A pressure-difference measuring member designed as a spring means transmits the reaction forces, acting on the sewing feet during the sewing operation, to the controller as a disturbance variable. To simplify this solution, a hydraulic difference-measuring member is provided instead of the mechanical pressure-difference measuring member. At the same time, the two chambers (82a, 82b) of the hydraulic cylinder (59) are connected to one another via two pressure-relief valves (71, 71') connected anti-parallel. Each pressure-release valve (71, 71') expediently consists of a spring-loaded non-return valve (R) and of a pressure-limiting valve (D) located downstream of the latter. <IMAGE>

Inventor: YAHAGI TOSHIO
IPC: B60T8/1761
Filed: 1989-07-24
Abstract: The speed of a vehicle equipped with antilock brakes is estimated from a wheel speed, an acceleration and a deceleration. At least the deceleration is based upon a differentiated value of a highest wheel speed of all wheels or, in a vehicle in which the drive wheels are rigidly coupled, upon a differentiated value of a highest value of the wheel speed of the driven wheels, and the lowest wheel speed of the drive wheels. As shown, in the first alternative the highest speed of the four wheels 2 is selected at 5 and differentiated at 7. Comparators 8, 11 use maximum and minimum values of decelerations A1, A2 to set switches 9, 12 to determine the value fed to arithmetic circuit 14. The outputs of circuit 14 are fed to front and rear wheel speed estimating means 6F, 6R which are input the lower of the front and rear wheel speeds respectively. Each speed estimating means 6 compares the previous speed estimate VFV with the present speed VFW in comparator 15 and operates switch 18F so as to either connect the speed signal VFW to the acceleration circuit 16F or to the deceleration circuit 17F. The new speed estimate VFV is fed to the antilock brake control circuits 1. <IMAGE>
