Patent DE-3810415-A1 (DE)
Title: Pump for pressures exceeding a thousand bar
Inventor: EICKMANN KARL
IPC: F04B43/067
Filed: 1988-03-26
Abstract: In pumps for non-lubricating fluid with delivery pressures exceeding a thousand bar, there is the problem that the service life is limited by the number of strokes of the separating parts and valves. Such pumps therefore have a low speed in order to achieve a sufficient hourly operating figure. Since the primary drive units, such as diesel engines or electric motors, run at high speeds, expensive and voluminous reduction gears were necessary, the service life of which was likewise limited and which, despite their high costs, caused noise and operational unreliability. The invention overcomes these difficulties in that it allows a distributor to rotate at low speed, which distributor then conveys pressure fluid to the high-pressure pistons - mostly with a medium-pressure piston intermediate stage - so as to allow the valves and separating means, such as the diaphragms, V-elements and the like, to work with a small number of strokes per unit time. In the case of other embodiments, the distributor is replaced by sequence signals which initiate the next piston immediately after the end of the pressure stroke of the previously forcing piston. Furthermore, details which promote the simplicity or the service life are described. A particularly practical exemplary embodiment uses a hydraulic motor of large absorption volume to drive the control shaft and thus forms the reduction ratio of a commercially available master pump for the unit of the invention.

IPC: G01N27/416
Filed: 1988-07-01
Abstract: The use of a sensor (4) for determining the relative humidity as an electrochemical voltage generator is proposed, at whose electrodes (2, 5) a voltage is produced which changes as a function of the relative humidity.

Patent DE-3824150-A1 (DE)
Inventor: ILSANKER ANTON
IPC: H01P1/161
Filed: 1988-07-16
Abstract: A waveguide twist for rotating the polarisation plane consists of rectangular hollow conductors wound constantly about its axis, but which require a not inconsiderable constructional length. In a conventional polarisation filter, although it is possible for the propagation direction to be positioned mutually parallel using an elbow, the polarisation planes are however rotated by 90 DEG  in the two waveguide branches. In order to provide a waveguide twist, especially for use in a polarisation filter having a small space requirement, with simple means, it is provided that two parallel adjacent waveguides are connected to one another via a common coupling window which is arranged centrally in the one waveguide in the longitudinal direction and off-centre in the other waveguide. When two rectangular waveguides are employed, the coupling window is arranged on the one hand centrally on the narrow side and off-centre on the wide side on the other waveguide. The waveguide twist is also especially suitable for polarisation filters. <IMAGE>

Patent DE-3828506-A1 (DE)
Title: Probe
Inventor: DAGENBACH STEFAN DIPL ING
IPC: G01B5/012
Filed: 1988-08-23
Abstract: A probe for three-dimensional scanning has in a housing a feeler element which is mounted therein capable of moving via a bearing device. The bearing device has on the feeler element a bearing body arrangement, which forms an approximately V-shaped notch with edges rising on both sides, and on the non-displaceable part, in particular the housing, likewise a bearing body arrangement which forms an approximately V-shaped notch with edges rising on both sides and whose respective V-peaks essentially lie on a common axis, which is coaxial with the longitudinal middle axis, and point in directions averted from one another. The two bearing body arrangements bear axially against one another, notch in notch, in the form of a cross and are held together by means of a resilient restoring force. Thus, pivoting movements of the feeler element in the X-Y plane, insertion movements in the Z-axis direction and also rotations of the feeler element about the Z-axis are respectively converted into essentially translatory movements and fed to a measuring element or detector for signal generation.

Title: Method for measuring the AM/PM conversion Kp and the compression C of a microwave link and circuit arrangement for carrying out the method
Inventor: DICK RUDOLF DIPL ING
IPC: H04B17/00
Filed: 1988-09-20
Abstract: These types of modulation distortion have previously been measured with constant modulation. The invention allows them to be measured modulation-dependently over the link. The section under test is supplied with a test signal with constant weak amplitude modulation percentage, the amplitude of which is swept between an (adjustable) maximum value which approximately corresponds to the modulation limit of the relevant section under test, and a minimum value, which is a fraction (about 10 %) of the maximum value in accordance with a known time variation, and an output signal of the section under test is examined for modulation-dependent variations of its phase modulation index and of its amplitude modulation percentage. In microwave links operated with QAM, the said types of modulation distortion can result in complete signal corruption. Their accurate knowledge is therefore of particular importance in this case. <IMAGE>

Title: Guide roll for a porous belt, for example a drying fabric of a paper machine
Inventor: MAYER WOLFGANG
IPC: D21F5/04
Filed: 1989-03-08
Abstract: A description is given of a guide roll for a porous belt, for example for the drying fabric of a paper machine. A perforated roll cover 2 rotates about a stationary air-guide box 3. The latter has two air chambers which extend over the length of the guide roll. One air chamber serves for blowing out blast air and the other for sucking up and carrying away suction air. Between the air-guide box 3 and the roll cover 2 there is an annular space 43, in which a blast zone B and a suction zone S are bounded by means of longitudinal seals 60, 61. Taking into account the fact that blast air and suction air can have different temperatures, the two air chambers of the air-guide box 3 can be displaced relative to each other in the axial direction.   <IMAGE>

Title: Multi-stage electrical switch - has compact pairs formed in A-stack to be actuated by plunger
Inventor: MAUSSNER LEONHARD
IPC: H01H13/64
Filed: 1989-06-10
Abstract: The multistage electrical switch is produced from a printed circuit foil (3) that is formed into a number of loops to create several contact levels (5). The axially aligned contact pairs are closed in sequence depending upon the force applied by a actuator pin (7). The top pair of contacts are formed on flat sections of the foil and are separated by a spacer. These contacts close first of all. A low contact pin has a greater separation due to the foil shape and close at a later stage. ADVANTAGE - Allows multiple contact closures dependent upon applied force.

Title: Photon current measuring device - has sec. electron multiplier with anode current supplied to microcomputer via A=D converter
Inventor: JANSEN GUENTER
IPC: H01J43/30
Filed: 1989-07-19
Abstract: A device for measuring photon current has a photo-multiplier (1) with a photocathode (2), a seat of dynades (3) and an anode (4).  The anode current is sent to a microprocessor (9) via an a-d converter (7).  When the current exceeds a predetermined value a switch (14) is operated to switch in a resistor (15) between the h.v. circuit (10), the cathode (2) and a voltage divider (12).  The resistor (15) causes a louvering of the cathode (2) and hynode (3)  voltages. The microprocessor (9) determines, by processing the measured value, the position of the switch (14) and, from that, the cathode and dynode voltages and the resulting anode current which is dependent on the intensity of striking photons. USE/ADVANTAGE - Much wider measuring range. Improves linearity between photon intensity and anode current can measure both short pulses of photon current and constant high currentsa.

Filed: 1989-07-28
Abstract: Liq. manure is stirred by a rotary worm (32) driven by a motorised unit (26) slidably mounted on a vertical rail (18) dipping into the tank. Air needed to maintain aerobic bacterial growth conditions is discharged into the stirred area from a flexible pipe (38) leading from the tank head.
