Title: Teleprinter group terminal system - has test circuit for classification of line signal distortion
Inventor: FIEBIG HANS-HELMUT DIPL ING
IPC: H04L12/26
Filed: 1980-03-31
Abstract: The system has station connector modules (LAM) which each cooperate with a group of stations (T1-n) having equal data rate characteristic, and there are as many such modules as are connected groups of stations with different bit step rates. Each connector module (LAM) is equipped with a test text storage unit (M) wherein test words with predetermined percentage distortion are memorised at addresses from which they may be non-destructively read out at a subscriber station for assessment of its receiving capability. The teleprinter transmitting system can also send out test words which are received by the respective microprocessor allotted to it (MP1-n) and assessed by it. Assessment of signal distortion is carried out by measuring the bit impulse duration and by associating with various durations definite distortion indications. While such test procedures are carried out the flow of incoming or outgoing data at the station-owned microprocessor is impeded.

Title: Run=out correction in continuous casting plant - by adding cold metal powder to mould so molten metal rapidly solidifies at run out, and casting can be resumed
Inventor: SPACCAROTELLA ANTONIO
IPC: B22D11/116
Filed: 1980-08-21
Abstract: If a run-out occurs, the flow of molten metal from a tundish into the mould is stopped; and 5-100 kg/minute of metal powder, size 0.1-5 mm is fed as a coolant into the mould via a funnel and pipe. Continuous casting is then restarted within a period of 0.1-5 minutes. The metal powder pref. has a higher m.pt. than the molten metal, which is pref. steel, in which case the powder is esp. steel with the highest possible Fe content. The cold powder causes rapid solidification of the ingot at the run-out so casting can be resumed within a short period.

Title: Photoreceiver with polychromatic colour band filter - made by successive applications using photolacquer at each stage
Inventor: STEMME OTTO DIPL PHYS DR
IPC: G02B5/28
Filed: 1980-09-30
Abstract: Method of making a photo-receiver with a polychromatic colour band filter is as follows. The alternating filter bands are laid on a substrate, typically of glass, in successive stages; in the first stage, the substrate is coated with a continuous photo lacquer, this is then exposed and developed using a grating of parallel lines to give intermittent parallel strips of lacquer (top view); then the first filter layer is laid entirely over the lacquer and the substrate (centre view), then the photo lacquer together with the layer of filter overlying it is removed, esp. using organic solvents, pref. dimethyl ketone, to give strips of the filter material only (bottom view). The process is then repeated, by again applying photo lacquer over the filter layers and substrate, removing the lacquer in intervening spaces, then applying the second filter layer, then removing the photo lacquer together with the overlying second filter layer, thus giving two different filter strips alternating. The process may be repeated with as many strips as desired. Pref., to produce the filter layers, chemically and mechanically stable evaporating materials, e.g. highly refractive materials such as Ta2O5, TiO2, CeO2, ZnS are used, and/or low-refractive materials such as MgF2, SiO2, ThO2. Photoreceivers or photo sensors with absorption-free, polychromatic colour band filters having very sharp characteristics and steep-flanked spectral transmission are obtained.

Title: Method for producing a connection part for inlet and outlet lines of flat radiators
Inventor: KOENIG HARRY
IPC: B21K1/14
Filed: 1981-04-02
Abstract: The invention relates to a method for producing a connection part for inlet and outlet lines of flat radiators. A disadvantage of known methods, which are based on the deformation of tube sections, is their relatively great hardness as a result of a carbon content of 0.15%. The cold forming in this case requires considerable forces, which can result in a disturbance of the fibre flow and the formation of weak points. The object is to provide a method for producing a connection part which has uniform quality in practically all areas. The invention proposes the cold deformation of a solid material of soft steel with a particularly low carbon content, the following method steps being carried out one after the other or in combination:       a) forward rod extrusion,   b) forward can extrusion,   c) forward hollow extrusion.   As a result of the deformation, the material is strengthened in the zones at risk, with the result that a re-hardening is generally unnecessary. <IMAGE>

Title: Device for generating steam
Inventor: BAUR PETER
IPC: F22B37/02
Filed: 1981-05-02
Abstract: A heat exchanger (4) flowed through by water is arranged in a waste-gas duct (1). Provided outside the waste-gas duct is a pressure vessel (8) which has a water chamber (9) and a steam chamber (10) and serves for the generation of steam. The water chamber (9) of the pressure vessel (8) is connected to the heat exchanger (4). Via an overflow valve (18), which is provided in a steam line (16) connected to the steam chamber (10), the pressure in the pressure vessel (8) is regulated depending upon the temperature of the waste gas behind the heat exchanger (4). In this case, the pressure is kept to a value which corresponds to a minimum temperature of the water flowing to the heat exchanger (4), which temperature is dependent upon the waste gas temperature, in order fully to utilise the waste gas heat with a simultaneous reduction in the low-temperature corrosion. <IMAGE>

Title: Accumulating roller conveyor
Inventor: ALBRECHT FRIEDRICH
IPC: B65G47/26
Filed: 1981-05-22
Abstract: An accumulating roller conveyor has conveyor rollers which are mounted so as to be freely rotatable, a drive belt which is guided below the said rollers and has pressing rollers which are situated below it, press the drive belt against the conveying rollers and effect concomitant movement of the latter. In the case of such an accumulating roller conveyor, it is intended to make it possible to stop the conveyed material using a barrier, without the accumulating force acting on the barrier becoming excessively large. After removal of the barrier, however, the accumulating roller conveyor must be able to start automatically. It is proposed to give at least part of the pressing rollers an eccentric shape, so as to bring about pulsatory control of the pressing force and therefore establish sufficient frictional engagement between the drive belt and the conveyor rollers to permit the conveyed material to start moving.

Title: Analog/frequency converter for forces and pressures, in particular for measuring flow rates and quantities
Inventor: WESP JOACHIM
IPC: G01F1/37
Filed: 1981-06-05
Abstract: The force to be measured is applied to a torsional pendulum mounted at the centre of mass and having a moment of inertia of  THETA , and thereby becomes the righting moment D. The result is an oscillating system whose natural frequency increases in strict proportion to the root of the force applied: <IMAGE> The excitation of oscillations is performed by means of a small magnet having an induction coil and of an iron core having an excitation coil, which are coupled in a simple amplifier circuit (see figure in the annex, or Fig. 5 of the patent application). Because of the radical relationship between the oscillating frequency and force, the measuring principle is especially suitable for flow measurements and quantity measurements by means of a body which is located in the flow tube, is subject to incident flow, and on which a driving force is produced which increases with the square of the flow rate. The measuring principle is largely capable of variation and extension, eg. for pressure measurements and measurements of heat quantity. Characteristics: extraction of root immediately at the measuring element, excellent reproducibility of the measured values; simple and robust design of the torsional pendulum; range of force measurement selectable within wide limits; low electronic outlay; teletransmission and recording of the measuring frequency possible with ease. <IMAGE>
