Title: Method and device for process calibration of optical fibre sensors in multi-phase systems
Inventor: HOFFMANN ALFRED DR ING
IPC: G01N21/85
Filed: 1986-03-25
Abstract: The invention relates to a method and a device for process calibration of optical fibre sensors which can be used in multi-phase systems for measuring the particle concentration, particle speed and particle size. For direct measurements in the disperse phase, the sensors are subjected to the physical conditions of the fluid systems. As a result, contaminations of their optical active surfaces with subsequent signal attenuation over relatively long operational periods cannot be avoided. The object of the invention is to perform the calibration of optical fibre sensors within the multi-phase system during the technological process in order to ensure the reliable monitoring and control of processes with multi-phase systems with uniform sensitivity of the measuring technology. The object is achieved in that the optical operational surfaces of the sensors are cleaned between the measuring processes, subsequently displaced in such a way that the measurement gap results in zero and that the pulsed calibration signals are compared according to frequency and amplitude in a comparison amplifier with a characteristic calibration value of the multi-phase system. When they coincide, the measuring operation is moved onto. When they do not coincide, the calibration signal is amplified electronically or optically.

Title: Process for the concentration of dissolved substances and plant for the concentration
Inventor: SEWING RAINER
IPC: B01D61/22
Filed: 1987-01-14
Abstract: The invention relates to a process and a plant for the concentration of substances, which are present in disperse or colloidal solutions, from a highly dilute starting material by ultrafiltration, in particular for the isolation of active compound in the medical or pharmaceutical sector. With the aid of a control apparatus, after presetting the parameters "inlet pressure" and "pressure difference", during an ultrafiltration program, the pressure difference over the filter elements is kept constant by influencing the pump output rate and by influencing the counter pressure with the aid of a throttle. Thus, over the entire program, despite the changing viscosity of the material to be filtered, an optimal filtration result is achieved.

Title: Geometrical reduction in the decalage for hang gliders having a flexible wing and gravity-force control, and simultaneous influencing of the profile (warping) in the trailing profile region
Inventor: NETZER ADALBERT
IPC: B64C31/028
Filed: 1987-10-27
Abstract: This geometrical reduction in the decalage with simultaneous influencing of the profile in the trailing profile region - curved-flap effect - is used to improve the flying performance of hang gliders having a flexible wing, without controllability and safety being adversely affected. In this case, each side of the wing is pulled down, approximately in the wing centre, by means of a forked cable in the rear profile region and on the trailing edge of the sail. These forked cables are connected on the left and right, by means of a cable, via deflection rollers. Different loads on the two wings are in consequence transmitted to the opposite wing and cause wing warping in the opposite direction. The tension in this system is variable by means of a pulley block and roller to the connecting cable running through the wing centre and can be varied by the pilot, at will, during flight.

Abstract: The electromotively driven door lock has a bolt (29) which is guided displaceably in a lock case (7) and which is coupled in the two directions of movement, via a push-face mechanism (61, 63), to a control part (43) displaceable transversely relative to the direction of movement of the bolt (29). The control part (43) is driven by an electric motor (37) via a gearwheel mechanism (41) and a rack toothing (59) provided on the control part (43). The electric motor (37) can move the control part (43) beyond the position assigned to the drawn-in bolt (29) towards a latch (9) of the door lock, the control part (43) taking up the latch (9) in the drawing-in direction. For this part of its stroke, the control part (43) can be driven pivotably or else take up the latch (9) via a sloping-face mechanism or a deflecting angle lever. The follower (21) provided for the manual opening of the latch (9) takes up the control part in the drawing-in direction of the bolt (29) via take-up stops (81, 83), so that, if necessary, the door lock can also be released manually. <IMAGE>

Title: Spring arrangement for the suspension of a motor vehicle
Inventor: BUFLER ERNST DIPL ING
IPC: B60G7/04
Filed: 1988-01-30
Abstract: In order to take account of the greatly varying loads of a motor vehicle, a progressively acting spring arrangement is often provided, which comprises a first spring device constantly acting between the vehicle body and the vehicle wheels, and a second spring device acting between them only intermittently, that is at higher vehicle loads. At the same time the second spring device takes effect only once the vehicle body is compressed by a certain spring travel owing to a corresponding static vehicle load, that is at a lower vehicle level. The new spring arrangement is particularly intended to ensure that, for an insignificant cost, the vehicle level remains at least approximately constant, even after loading. For this purpose, the second spring device is designed as auxiliary spring which, as necessary, especially in the event of a variation of the vehicle loading, can be brought from a rest position lying outside the compression travel of the wheel suspension elements into a working position lying inside the compression travel and vice versa.
