Patent DE-3335453-A1 (DE)
Title: Grooved combination post
Inventor: AHRENBECK REINER
IPC: E04C3/30
Filed: 1983-09-30
Abstract: The square or rectangular post has, in the centre of all four sides in the longitudinal direction, a groove of the same size and, in the upper part of the post, additionally an oblique groove in each case. The post is intended to be used as support for storage or accommodation areas, such as for a car-housing area/carport, equipment housings, a pergola or the like. The groove which runs in the longitudinal direction in the centre of each side of the post and is of the same size on each side makes it possible for boards to be pushed into the longitudinal groove when two posts are erected in parallel. Even in the case of a sheltered storage or accommodation area which has already been erected, it is possible to push boards into the longitudinal groove subsequently, by using the oblique groove, and thus to produce connecting walls. Since each side of the post is provided with the longitudinal groove and the oblique groove, angle combinations may also be selected without difficulty when producing partially or wholly enclosed storage or accommodation areas.

Title: Method for transmitting a relatively high resolution television signal
Inventor: HABERMANN WERNER DIPL ING
IPC: H04N11/24
Filed: 1983-11-15
Abstract: For the compatible transmission of a relatively high resolution television signal (HDTV signal) using satellite direct television transmission channels, it is proposed that the HDTV signal be converted by means of vertical filtering into a television signal whose number of lines and frame repetition frequency correspond to those of a conventional television standard. During the conversion of the HDTV signal, in addition to the vertical filtering, horizontal filtering takes place with a low-pass characteristic at a limiting frequency, which is produced taking into account an image side ratio (for example 5:3) which is increased in comparison with the conventional television standard, with the same vertical and horizontal resolution. The frequency band which is fixed by the limiting frequency is split into a lower part of, for example, 0-5.75 MHz and into an upper part of, for example, 5.75-9.2 MHz. The upper part of the frequency band is converted in terms of its frequency and is compressed in time. Of the lower part of the frequency band, the temporal edge sections corresponding to the difference between the enlarged and the standardised image side ratios are separated and both the separated and the remaining centre section are temporally expanded. The temporally expanded edge sections are temporally multiplexed with the converted and temporally compressed upper part of the frequency band.

Title: Door leaf
Inventor: KREMER PIUS
IPC: E06B3/70
Filed: 1983-12-14
Abstract: A door leaf usually consists of a rail frame and a core (23), via which the covering plies (21 and 22) are interconnected, the rail frame forming a rebate on three sides of the door leaf, in association with the covering plies. The rail frame consists in this case of three sections (1) of an aluminium profile, which are mitred and interconnected. The aluminium profile has in cross-section a sturdy web (2) which runs through between the spacing of the covering plies (21, 22) and is sunk by at least the depth of a lock plate (24) of a door lock (20). The aluminium profile has at least one freely ending receiving rib (14) which is sunk by the depth of the lock plate (24). <IMAGE>
Patent DE-3406428-A1 (DE)
Title: Copying frame with masking device
Inventor: HEIDENREICH WALTER ING GRAD
IPC: G03B27/28
Filed: 1984-02-22
Abstract: The application relates to a copying frame for a copying machine for exposing photoactive printing plates with a masking device. The latter comprises mask webs of opaque material which can be adjusted within their plane on the glass plate of the copying frame and which enclose, with their inner edges, a transillumination window of variable position and size on the glass plate. The object of the invention is to improve such a copying frame with masking device by fabricating the mask webs from a material which, without the application of force at the inner edge situated towards the transillumination window, can be pushed out in the direction towards the centre of the glass sheet of the copying frame in order to simplify thereby, at the same time, the design of the translation devices for the mask webs. This is achieved in that the mask webs consist of a flexible material, which is stiff in the direction of their planar extent and is thus transversely rigid, and in that at the edge of the copying frame, winding devices are arranged for the mask webs, which devices have a pushing-out drive and a pulling-in drive for the mask webs.

Title: Method and apparatus for the continuous casting of metals, especially steel
Inventor: PLESCHIUTSCHNIGG FRITZ-PETER D
IPC: B22D11/00
Filed: 1984-02-24
Abstract: Methods and apparatuses of this kind are used for casting thin strands with a high output, i.e. a relatively high casting rate. With these methods and apparatuses, the aim is to produce a surface which is free of transverse and longitudinal cracks and is without casting marks. The aim is to eliminate the disadvantages caused by a moving mould, i.e. the oscillation marks formed, in the continuous vertical or horizontal casting of metals with an oscillating mould or with a relative motion between the cast strand and the horizontal continuous casting mould, in order thereby to achieve a higher surface quality. For this purpose, it is proposed that the molten metal (1) be introduced at the outlet of the nozzle (3) adjoining the pouring aperture of the continuous casting mould (4) and that a metal foil (5) be in each case taken along continuously during casting, at least at two opposite cross-sectional sides, at the withdrawal rate (6) of the cast strand (7). The transition from the nozzle (3) to the continuous casting mould (4) or casting space (4a) of the latter by the flow of molten metal is made with the formation of a stationary meniscus (8) while maintaining a dynamic equilibrium of the flow parameters. <IMAGE>

Title: Process and apparatus for treating molten nonferrous metals and/or their slags by reaction gas top blowing
Inventor: BARIN IHSAN PROF DR
IPC: C22B7/04
Filed: 1984-06-01
Abstract: In a process for treating molten nonferrous metals and/or their slags by reaction gas top blowing, especially in the case of the reduction of the melt by means of a high-velocity jet, part of the reductant has to be burned in order to achieve the required reaction temperature and to cover heat losses of the reactor. As a result, the driving concentration gradient is disadvantageously reduced. The invention achieves a considerable improvement in that the reaction gas used is a plasma gas. A reactor for carrying out the process has a plasma burner. <IMAGE>
Patent DE-3421758-A1 (DE)
Inventor: ROTHKEGEL BERNHARD
IPC: H01H1/02
Filed: 1984-06-12
Abstract: Contact materials based on AgSnO2 and having Bi2O3 and CuO as further metal oxide additives were previously disclosed. In these materials the total content of all metal oxides was supposed to be between 10 and 25% by volume with the SnO2 share equal to or greater than 70% by volume of the total amount of oxide. According to this invention the quantity of SnO2 is kept smaller than 70% by volume; specifically at about 65%, but in any case equal to or greater than 50%. The SnO2 weight content is to be in the 4% to 8% range and the weight percentage ratio of SnO2 to CuO is to be between 8:1 and 12:1. In the associated production process, either Bi2O3 powder is purposely admixed to an internally oxidized alloy powder (IOAP) in an additional operation, a grain restructuring with locally different Bi2O3 concentrations occurring in the structure after sintering and compacting. Alternatively, higher bismuth percentages in the alloy powder can be worked with directly, which is again internally oxidized to an IOAP. From these starting materials two-layer sintered contact elements with a solderable silver layer can be efficiently produced.

IPC: A61C17/20
Filed: 1984-06-19
Abstract: In a dental ultrasonic handpiece having a magnetostrictive oscillator system which is driven by a field coil arrangement, a further coil is inductively coupled to the field coil. An illuminating device, which consists of miniature incandescent lamps, for example, is connected to this second coil. The illuminating device is thus fed from the field coil by the transformer effect. The handpiece either forms an integral unit with the illuminating device or is structurally separated from it, the illuminating device being constructed with the second coil in the latter case in the form of a cap which is placed onto the handpiece. <IMAGE>

Title: Arrangement for controlling a hydraulic actuating device
Inventor: STOCKBAUER GERT DIPL ING
IPC: F15B11/042
Filed: 1984-06-22
Abstract: An arrangement (10) for controlling the rapid traverse and feed of a hydraulic actuating device is proposed, the hydraulic motor (11) of which can be controlled in both directions with regard to direction and speed. Lying between a proportional valve (15) and the hydraulic motor (11) in one (24) of the working lines (22, 24) is a pressure balance (33) which interacts with the proportional valve (15) as a flow controller, for which purpose both valves (15, 33) are connected to one another via control lines (38, 39) in which an additional, switching 4/2-way control valve (42) is connected, while a counterholding pressure valve (47) lies in the other working line (22). The controllable pressure balance (33) works as a downstream inflow controller during forward feed and as an upstream outflow controller during reverse feed and at the same time as a counterholding pressure valve. In addition, to avoid starting surges, the pressure balance (33) can activate its control position starting from a blocking position. <IMAGE>

Title: Process for casting-on straps and terminals onto pre-assembled plate groups of electric accumulator cells
Inventor: BECHTOLD DIETER DIPL ING
IPC: B22D19/00
Filed: 1984-09-22
Abstract: The melting-on process of the straps and terminals onto the current-carrying lugs, which proceeds, according to the cast-on straps (COS) principle, in a casting mould 1 designed as a two-cavity die, is terminated, in view of possible differences of the lug thicknesses in the positive and negative plate group halves, by differential cooling. After simultaneous lifting of the cooling vessels 6, 7 against the moulds into a first position, at a cooling water level a, has first caused both terminals to solidify, cooling is continued at the cooling water level b, using a timer-controlled lead time in favour of the strap type which has the thinner lugs attached to it (in this case, for example, the negative type), so that the thicker lugs of the positive plate group half are exposed to the molten lead in accordance with their greater heat requirement. <IMAGE>

Title: Device for producing large cylindrical containers by winding resin-impregnated fibres (rovings)
Inventor: VOSS ADOLF PROF DIPL ING
IPC: B29C53/70
Filed: 1985-03-27
Abstract: With the device according to the invention, large cylindrical containers and pipes (also including sockets) can be produced at the site of erection by winding resin-impregnated fibres (rovings). A rail system is provided which runs concentrically around the winding mould and receives at least two carriages. On a penultimate carriage there is arranged a frame with filament spools, on the last carriage is a resin bath which can be moved up and down on a column. An arm is attached pivotably on the rear side of the resin bath at the end of which arm is disposed the winding head with which the impregnated filaments can be brought into a vertical arrangement suitable for winding. By moving the train of carriages on a special rail system and by the common vertical movement of resin bath and winding head, it is possible to wind the mould from the very bottom to the top without restriction. Moulds can be wound whose diameter is much smaller than the diameter of the rail system. <IMAGE>

Title: Projectile
Inventor: WALLOW PETER DIPL ING
IPC: F42B10/06
Filed: 1985-04-27
Abstract: In the case of a sub-calibre, wing-stabilised projectile 10, wings which form a fin system are arranged in the tail region of a penetrator 11. The wings 12 are of swept-forward construction in such a manner that the wing-tip 12b points in the direction of flight of the projectile. When it strikes a target on a target surface 13 which is in an inclined position, a relatively small force R' is transmitted to the impacting wing 12. However, this force is aligned essentially parallel to the longitudinal axis of the penetrator 11 and thus does not lead to a bending torque which destroys the penetrator 11. In consequence, the final-ballistic performance of the penetrator 11 is completely maintained. <IMAGE>

The used filtering fuel, before it is added to the process fuel and itself burnt, is separated from dust and finely divided gypsum resulting from the lime/sulphur dioxide reaction. These portions are not introduced into the combustion zone, in order to avoid additional loading of a fresh solid fuel filter layer.
Patent DE-3542757-A1 (DE)
Inventor: WIESENBERGER ALFRED
IPC: C12G3/08
Filed: 1985-12-04
Abstract: A process is described for preparing in particular alcohol-free wine in which by extraction with supercritical CO2 firstly a specific aroma fraction with limited ethanol content is separated from the starting wine. The residual wine is then subjected to a vacuum distillation in which apart from the complete separation of the ethanol from the residual wine a fraction of more difficulty extractable aromatic substances not affected by the extraction is recovered which in the end together with the extract is added to the dealcoholized residual wine again to obtain an alcohol-free wine. The method permits an almost complete removal of the alcohol content without detrimentally affecting the basic wine and with retention of all the aromatic and flavoring substances characteristic of the wine.
