Title: Method for the fully continuous casting of molten metals
Inventor: HEINKE RUEDIGER DR ING
IPC: B22D11/08
Filed: 1982-12-14
Abstract: The invention relates to a method for the fully continuous casting of molten metals, in particular alloy steel, in which melts with different alloy contents are emptied one after the other into a tundish from ladles. From the tundish, the melts are cast via a casting pipe in an open die to give a continuous strand. After a ladle has been emptied, the slag-covered melt still in the tundish is poured out bar a residual quantity before the next melt is poured in. The invention is characterised in that, upon transition to a following melt with a higher alloy content, the residual quantity of the melt in the tundish has added to it those alloy constituents of the following melt which it lacks.

Title: Galvanic Li/SO2 secondary cell
Inventor: KRUGER FRANZ JOSEF DIPL CHEM D
IPC: H01M10/0566
Filed: 1983-03-29
Abstract: In a galvanic lithium cell containing liquid SO2 as cathode depolariser, triethyleneglycol dimethyl ether (Tri-DME) is used as co-solvent and electrolyte solvent. This ether combines an extremely high SO2 absorption capacity along with an increased solvation capacity for conducting salts, resulting in beneficial conductivities in the order of magnitude of 10<2>  OMEGA <1>.cm<1>. The good compatibility of the Tri-DME/SO2 mixture also suggests its use as an additive for organic electrolytes for other Li systems such as Li/MnO2 or Li/CrOx.

Filed: 1983-03-31
Abstract: Method and apparatus for the correction of image distortion in the digital transmission of video signals, in which at the receiving end a comparison is made between the received signal values and estimated video signal values computed from adjacent video signal values. When a prescribed threshold value is exceeded by the amount of the difference between the video signal value and the associated estimated video signal value, the corresponding estimated video signal value is forwarded instead of the received video signal value. A feature of the present method and apparatus is their ability to distinguish edges of objects when there are sharp fluctuations in expected signal level values.
Patent DE-3313344-A1 (DE)
Title: Absorption material for water, aqueous solutions and aqueous body fluids
Inventor: CHMELIR MIROSLAV DIPL CHEM DR
IPC: A61L15/60
Filed: 1983-04-13
Abstract: The invention relates to a process for producing an absorption material for water, aqueous solutions and aqueous body fluids, which absorption material is composed of an absorbent, permanently fixed on or in a support, and which is produced by treating the support with the partially swollen absorbent and then drying it. The partial swelling of the absorbent is carried out exclusively with water, that is in the absence of an organic solvent. The partial swelling of the absorbent can be controlled in the production of the absorbent through the water concentration. When the absorbent is applied between two support layers which have recesses, the partial swelling is carried out after the application. The invention further relates to the use of the absorption material thus produced in disposable products for hygienic, surgical or other medical purposes for receiving and/or retaining water and subsequent controlled delivery of water or components dissolved therein to other bodies, for example plants, and finally as a filter insert in smoking materials to absorb distillation products contained in the smoke.
Patent DE-3315238-A1 (DE)
Title: Method for volume measurement
Inventor: WEBER NIKOLAUS DIPL ING
IPC: G01F17/00
Filed: 1983-04-27
Abstract: A method for measuring the volume of cavities, in which the cavity is evacuated and the volume is subsequently determined by the admission of air, is proposed together with a device suitable for carrying out this method. In this case, the cavity is evacuated to a pressure which is higher than the water vapour pressure, dependent on temperature, and lower than 500 mbar. A limited quantity of air is then admitted via a metering valve (8), and in this way a rise in pressure is produced to a value which is likewise still less than 500 mbar. In order to determine the volume in accordance with the formula V = Q. DELTA t/ DELTA p, the time is measured in which this pressure change takes place. Before admission of the air, it is possible to undertake monitoring for the presence of leaks, by temporarily switching off the vacuum pump when the pressure is higher than the water vapour pressure and observing the pressure change occurring in this time. Finally, before measuring the volume of the cavity it is possible to undertake evacuation of the cavity down to the water vapour pressure, in order to establish the presence of hidden accumulations of water. If the latter are present, it is expedient not to terminate the evacuation until the water vapour pressure is undershot, in order to dry out the accumulations of water. <IMAGE>

Title: Yagi antenna array with a sector-shaped polar diagram
Inventor: HOLLMANN HEINRICH DIPL ING
IPC: H01Q19/28
Filed: 1983-04-29
Abstract: The invention relates to a Yagi antenna array, having a plurality of Yagi antennas arranged in a row, in which, in order to achieve a sector-shaped polar diagram, the outer Yagi antennas are loaded in antiphase and at a reduced amplitude in comparison with the inner Yagi antennas. The object of the invention is to create a sector antenna from a small number of identical antennas and having a very simple network structure. To this end, the two outer Yagi antennas 7, 8 of only four identical Yagi antennas are loaded with a reduced amplitude via a commercially-available attenuating element 5 (with 3, 6 or 10 dB), their gain is considerably lower than the resulting gain of the two inner antennas 3, 4, which are loaded in phase and homogeneously; the mutual separation 12 of the inner antennas is small (12 = 0.588 W) in comparison with the operating wavelength W, and the central separation 13 of the outer antennas is large (13 = 1.5 W) such that, in their sum polar diagram, the second null point coincides with half the beam angle of the sector diagram. This antenna array is particularly suitable as a permanent station antenna in the 10-centimetre waveband (German Federal Post Office öbL-Network C) in the future public mobile state radio network. <IMAGE>

Patent DE-3316210-A1 (DE)
Title: Device for trimming wooden boards
Inventor: FROEHLICH ADOLF
IPC: B27B31/00
Filed: 1983-05-04
Abstract: The device serves to trim wooden boards, in particular intermediately stored boards also made of hard wood, which have warped again. The device works with two slides 1, 2 which lie above the work table and above one another and feed the boards to the cutting tool. Here, either the rear edge of the leading board is used as a stop for the front edge of the trailing board or two light barriers 10, 11 are provided in order to establish the cutting plane. The rear edge of the leading board is trimmed at the same time as the front edge of the trailing board is trimmed. The cutting plane is established either by a cutting tool which can be more or less wide or by two cutting tools driven and moving together and simultaneously. The second slide, which is designated as magazine slide 1, pushes the wooden boards out of the magazine, in the course of which these wooden boards bear on the work-table slide and are moved relative to the latter. The work-table slide 2 is then moved in such a way that the board pushed out of the magazine falls onto the work table and can be moved by the work-table slide into the cutting plane. <IMAGE>

Title: Device for the opening and transfer to a filler neck of sacks which are open at the top
Inventor: MUELLER MATTHIAS
IPC: B65B43/30
Filed: 1983-06-01
Abstract: In the device for the opening and transfer to a filler neck of sacks which are open at the top, the two sides of the sack (1) lying against each other are separated in the opening station by two suction strips (4, 5) which are movable in opposite directions. It must be ensured in this process that the sack opening which has been formed is preserved as the sack is transported from the opening station to the filling station. To this end, spacers (7, 8), which are arranged in the immediate vicinity of the inside folding lines of the side folds in side-folding sacks, are introduced into the pre-opened sack. The rectangular filling opening of the sack which has been produced by means of the suction strips is preserved by the spacers on the transport path from the opening station to the filling station, so that the vertically movable filler neck can be inserted into the sack opening in the filling station (Fig. 1).

Patent DE-3326138-A1 (DE)
Title: Force/pressure converter
Inventor: EBACH MANFRED ING GRAD
IPC: G01L1/02
Filed: 1983-07-20
Abstract: A force/pressure converter having a control element on which the force to be converted acts and which interacts with two valve seats of different diameter, in each case as a restrictor, the one valve seat being connected to a supply line for air at constant pressure and the other valve seat operating as an outlet, and the pressure which is proportional to the force to be converted being picked of between the valve seats. In this force/pressure converter, there is a precisely inversely proportional relationship between the input force and the output pressure. If the control element is designed as a permanent magnet and is arranged inside an electromagnet, then this arrangement can also be used as a current/pressure converter, since the current flowing through the electromagnet produces a magnetic field which exerts a force proportional to the current on the control element.
