Title: Data communication network with optical channels
Inventor: BACHUS ERNST-JUERGEN DR ING
IPC: H04Q11/00
Filed: 1982-10-08
Abstract: According to the heterodyne principle, optical channels for narrowband and broadband services can be made available in very large numbers to the subscriber stations which can be connected in the communication network via a single-mode fibre as the transmission medium. These channels can also be switched according to the heterodyne principle with random access with no connecting path network in the conventional sense, by combining all receiving devices via a common optical frequency channel multiplex with all transmitting devices. The tuning to a channel to be received is carried out by means of a tunable local laser. The intermediate frequency lies within the microwave range. The intermediate frequency filter has fixed tuning.

Title: Collating device for sheet collecting devices
Inventor: STOERR RUDOLF
IPC: B65H7/06
Filed: 1982-12-02
Abstract: The invention relates to a device for checking that collected signatures are in the right order, for use in sheet collecting devices with sensors arranged at the individual feeder stations offset transversely to the direction in which the sheets are drawn off for detection of appropriately arranged collating marks on the sheet and in order to emit a signal if there is an error in the sequence of sheets. The aim of the invention is to produce a collating device with a high degree of reliability of display which permits marks to be as small as possible and whose operating costs are low, in order to avoid unnecessary error messages. The object is to organise the acquisition and evaluation of measured values in a collating device in such a way that the effect of folding tolerances and the positions of the sheets in the magazine do not have an adverse affect on the displayed result and that stationary sensors can be used for all sheet sizes. This object is achieved by arranging optoelectronic detectors in the area in which the sheets to be drawn off are stacked, which sensors, in order to provide a standard of measurement for the various light values acquired, detect changes in the voltage, which are then checked for the signal sequence "dark/light" by a logical unit within a specific phase of the operating cycle.

Patent DE-3301885-A1 (DE)
Title: Wind generator
Inventor: QUANTE HEINRICH
IPC: F03D1/04
Filed: 1983-01-21
Abstract: A wind power installation having moving parts consisting only of turbine and generator delivers an efficiency of approximately 100 DEG in the conversion of wind energy into electrical energy. Turbine and generator are arranged at the lower end of a cylindrical tube acting as a type of funnel in such a way that the turbine is driven by the quantity of air moving upwards in the cylindrical tube. The required draught in the cylindrical tube is generated and favoured by surrounding the upper end of the cylindrical tube by a cylinder which has a larger diameter and is open at the top and bottom. A wind guide channel whose shape and feed are constructed to favour flow is produced between the two cylinders. Provided for this purpose on the cylindrical tube is a guide skirt which is constructed in the shape of a bell and which increases the quantity of the air introduced into the cylinder. <IMAGE>

Patent DE-3322100-A1 (DE)
Title: Flexurally rigid telescopic supports
Inventor: VOGEL RUDOLF DR ING
IPC: B66C23/70
Filed: 1983-06-20
Abstract: Hydraulic telescopes in particular are known as multiple telescopes for supports and masts. But these telescopes, due to the system, are very restricted with regard to telescoping lengths and speeds and transfer of bending moments. To largely eliminate these restrictions for running the tubes, one or more thin, highly elastic, transversely arched, driven bands guided in the telescopic support are arranged according to the invention, which bands, in interaction with the tubes, form a supporting system for general external loading. To keep the friction between the tubes low when telescoping under a bending moment, they are supported by rollers or rolling bodies combined in a device, rollers, for example, being held pressed against the telescopic-support contour in a concentrically path-controlled manner by spiral discs. The gradual infeed of the rollers to the telescopic-support contour is controlled by the tube steps themselves and is also performed by the drive of the bands. The bands are preferably transversely troughed in a plastic manner and for driving and storage are transferred elastically into a planar state by a supporting transverse formation. <IMAGE>
Patent DE-3322199-A1 (DE)
Inventor: RICHTER HANS
IPC: B25J9/00
Filed: 1983-06-21
Abstract: A robot arm consisting of an upper arm link and a lower arm link which are interconnected by a uniaxial joint. The upper arm link is connected with a structure via a universal joint. In order to attain a weight balance, a bellcrank level is placed on the upper arm link, on whose one lever arm an upwardly directed equalizing force acts and whose other lever arm is connected to the lower arm link. If both arm links are in alignment with one another, then the point of application of force on the one lever arm has its greatest distance to the universal joint. If, on the other hand, the lower arm link is swung out of its alignment with the upper arm link, then the distance between the point of application of force and the universal joint is decreased.

Title: Arrangement for measuring the working position of a vertically adjustable pick-up device of a harvesting machine
Inventor: ZIEMS HORST
IPC: A01D41/14
Filed: 1983-07-23
Abstract: The subject of the application is an arrangement for detecting the actual value of the working position of a vertically adjustable pick-up device of a harvesting machine, such as the cutting and drawing-in unit of a combine harvester, having a displacement sensor. This displacement sensor possesses a series of reed switches and at least one switching magnet movable along the reed switches, these elements of the displacement sensor movable relative to one another being coupled, on the one hand, to the pick-up device and, on the other hand, to the machine frame or a ground tracer, and the reed switches being connected electrically to a control or regulating device of an actuating drive of the pick-up device. In such an arrangement, the outlay in terms of wiring for the reed switches is to be reduced considerably and made independent of the number of particular reed switches used. For this, a voltage divider is formed from passive electrical components and a respective tap takes place at the connection between two of the components via the reed switches, the reed switches being connected, on the other hand, to a common return wire, and a current source being connected to the input of the voltage divider and to the return wire of the reed switches. At the same time, a voltage can be tapped as a displacement measurement between this input and the return wire.

Patent DE-3402287-A1 (DE)
Title: Overfilling prevention mechanism
Inventor: MEIER RENE
IPC: B01D1/00
Filed: 1984-01-24
Abstract: This device is installed in a solvent treatment plant in a vacuum evaporator (1.2) of a heat exchanger (1.1). It ensures that in the event of a failure of a filling valve (1.6), the level of the washing solution in the vacuum evaporator (1.2) cannot rise to any level. A ball float, projecting into the vacuum evaporator (1.2), of an overfilling valve (1.7), in the normal mode exerts a pressure, via a double lever and a valve push rod, on a valve ball and a valve seat and holds the valve in a closed position. When the level increases, the ascending force from the washing solution acts on the ball float as a result of which the pressure on the valve seat decreases and the valve opens. In this case, air enters through the overfilling valve (1.7) into the vacuum evaporator (1.2). The vacuum built up breaks down and thus the suction force utilised to suck in the washing solution is absent. Washing solution is only resupplied to the vacuum evaporator (1.2) when the level in the vacuum evaporator (1.2) has reduced by discharge of residues and the filling valve (1.6) is cleaned. <IMAGE>
