Patent DE-3803104-A1 (DE)
Title: Circuit arrangement for correcting weak analogue voltages of measurement value transmitters in the case of severe non-linearity
Inventor: STROBEL HENRY
IPC: G01R15/00
Filed: 1988-02-03
Abstract: The invention relates to a circuit arrangement for correcting or processing weak analogue measurement voltages of sensor elements in which offset and signal voltage are spread over a wide range and are highly temperature-dependent. The measurement voltages are amplified and supplied to an analogue/digital converter, from which they are retrieved for the microcontroller. The microcontroller supplies the digital correction signals as control signals to the amplifier which in each case follows the measurement value transmitter. The special construction of the amplifier makes it possible for the control signals to change both the gain and its offset and to correct the weak analogue measurement voltages during their amplification. The entire circuit arrangement can be actively calibrated by directly supplying the output signals of a temperature sensor to the analogue/digital converter. <IMAGE>

Title: Method of producing cotton swabs and plant for performing the method
IPC: A61F13/20
Filed: 1988-02-11
Abstract: In a method and a plant for the production of cotton swabs from a cotton band which comprises layers of meltable fibres at least in its surface and from which cotton swabs are punched out, the cotton band is selectively heated and cooled over parts or all the areas within the peripheries of the cotton swabs for melting the fibres that are meltable at least in their surface for connection to adjacent fibres. Those parts of the cotton band which lie outside the sections treated by heating remain in their untreated state, so that they can easily be processed again. The cooling device has an expediently matching outline. <IMAGE>

Title: Multi-plane cleaning device for combine harvesters
Inventor: BAUMGARTEN JOACHIM
IPC: A01F12/44
Filed: 1988-02-12
Abstract: The invention relates to a multi-plane cleaning device for combine harvesters having an upper screen and a lower screen, with the upper screen comprising a plurality of individual part screens which are arranged so as to be offset with respect to one another in different planes and between which are attached fall steps through which air flows. The essential features of the invention consist in that the individual part screens (5, 6, 7) have different lengths, the lengths of the part screens (5, 6, 7) increasing in the conveying direction (F). The individual fall steps (8, 9, 10) have different heights. The height of the fall steps (8, 9, 10) decreases in the conveying direction (F), and the distance of the fall steps (8, 9, 10) from one another increases in the conveying direction (F). The height of the fall steps (8, 9, 10) and the length of the part screens (5, 6, 7) are dependently related to each other in such a manner that as the length of the part screens (5, 6, 7) increases, the respectively assigned height of the fall steps (8, 9, 10) decreases. <IMAGE>

Title: Cordless telephone system
Inventor: HINRICHS KLAUS
IPC: H04M1/72513
Filed: 1988-04-30
Abstract: A cordless telephone system consists of a central device and a multiplicity of portable devices, in which arrangement voice connections can be established between the portable devices themselves and also between the central device and the portable devices. The central device is connected to a telephone switching system like a telephone set, which makes it possible to establish voice connections between a telephone set and a portable device. Such a cordless telephone system is to be developed in such a manner that it can also be used for data acquisition. The portable devices (G) are equipped with a barcode reader, the information picked up by the barcode reader being stored in a memory. The stored information can be transferred to an evaluating and control device via a connection which extends via the central device and the telephone switching system to this evaluating and control device. As an example, the use of a telephone set connected to the telephone switching system can be released or blocked by means of the barcode information. <IMAGE>

IPC: G01D21/00
Filed: 1988-05-19
Abstract: The invention relates to a method for monitoring wire stapling in book binding machines, especially the insertion of staples into booklets in the case of sections of saddle stitching booklets. The aim of the invention is to produce a method which enables the quality of the objects being processed to be increased and the occurrence of waste to be reduced. The object of the invention is to design the method is such a way that defective wire joints can be detected independently of the operating speed. The object is achieved in that a signal pattern, which is made up of a multiplicity of measuring points, is obtained for the wire stapling of a design product and stored, point-by-point comparison with the signal values for wire stapling of actual products is carried out and differences between desired and actual signals which are outside predetermined tolerance limits are indicated as defective wire stapling. Application of the method makes it possible to carry out point-by-point quality control of the wire stapling and the detection of deviations within tolerance limits. <IMAGE>

Title: Process and apparatus for drawing over a stack a cover comprising a sheeting of plastic
Inventor: LUEKE MANFRED DIPL ING
IPC: B65B11/02
Filed: 1988-08-23
Abstract: By the process according to the invention and the apparatus operating according to the said process it is intended for a shrinkable cover to be drawn over the upper region of a stack of bricks or tiles. When so doing, it is to be avoided that parts of the material lie one on top of the other.

The tape is only folded once about approximately 180@ in the region of the slot and the folded tape region is held in a positively locking manner in the clamp slot. <IMAGE>
Patent DE-3837032-A1 (DE)
Inventor: OBERDOERFER HANS
IPC: E03C1/10
Filed: 1988-10-31
Abstract: An anti-syphoning valve (12) which is suitable especially for incorporation into sanitary fittings comprises, in a housing (1), a chamber (10) into which a water inlet conduit (9), a water outlet conduit (8) and a ventilation channel lead. A resilient closing flap (16) comprises a fastening portion (18) and a closing portion (19) connected hinge-like thereto. Normally, that is, provided there is no negative pressure in the inlet conduit, the closing portion covers the opening of the ventilation channel leading into the chamber, so that, on the one hand, no atmospheric air can enter and, on the other hand, no water can escape. If, however, a negative pressure arises in the pipe system connected to the inlet conduit, the closing portion of the closing flap pivots through a certain angle until it seals the inlet point of the conduit leading into the chamber and, on the other hand, frees the ventilation channel to the chamber. In this way, no more water can flow back into the inlet conduit and to the pipe system connected thereto; on the other hand, the water passages downstream of the chamber are ventilated. The sucking back of contaminated water into the drinking-water system which is connected to the inlet conduit is thereby reliably prevented. The anti-siphoning valve is of such small construction that it can be accommodated especially in the bottom region of known sanitary fittings.

Patent DE-3927662-A1 (DE)
Inventor: DEUSS MATTHIAS DIPL PHYS ING
IPC: F42C13/02
Filed: 1989-08-22
Abstract: A device for detecting an object such as a tank in a target area and for causing a horizontal mine to be fired at the object, comprises first and second microphones which detect noise, including noise from a tank, in the target area, in infrared sensor having a directional characteristic which is narrow with respect to the target area and which extends towards the center of the target area to define a target window, and an electronic evaluation unit. The electronic evaluation unit receives acoustic signals from the microphones and calculates a correlation function from the acoustic signal. If a property derived from the calculated correlation function, for example, the correlation or the correlation gradient, exceeds a predetermined threshold, the firing mechanism of the horizontal mine is enabled. If the infrared sensor also detects the presence of an object within its target window, the electronic evaluation unit will cause the horizontal mine to be fired.
