Title: Large-bale opener for dry agricultural material
Inventor: NOSS JOACHIM
IPC: A01F29/00
Filed: 1982-05-28
Abstract: Large-bale opener which, by the continuous-flow process, meters large bales of dry agricultural material by volume and, at the same time, comminutes the initial products consisting of hay and straw. Large-bale openers known hitherto feed the large bales in batches and do not allow any exact metering by the opening tools. A high technical outlay is necessary for the metered feeding of follow-up appliances and for bringing up the following bales. Operating reliability is ensured only for a fixed shape of bale. The large bales are placed in succession on an endless feed band and are brought directly up to the cutting tools. The feed speed can be regulated as desired. An exact metering by volume is obtained from the feed speed and bale cross-section. The cutting tools consist of a plurality of horizontally arranged rotating rollers, on which cutting knives are accommodated in a V-shaped manner so as to overlap and extend spirally round. The rollers are located above one another in such a way that the one which is respectively located above is arranged offset oppositely to the feed direction. This large-bale opener is preferably suitable for the direct and variable feeding of follow-up appliances, such as: straw-heating boilers, briquetting machines, straw mills, blowers and storage silos. A general diagram is given in the drawing. <IMAGE>

Title: Method and arrangement for signal processing in a radar system
Inventor: LUDLOFF ALBRECHT ING GRAD
IPC: G01S7/34
Filed: 1982-10-07
Abstract: In a radar system with time-dependent and particularly disturbance-adaptive receiving channel control, the deviation of the set time-dependent attenuation from a predetermined and stored attenuation characteristic is determined and supplied again to the signal at the correct time as correcting factor in a later processing step. The predetermined attenuation characteristic can be selected in such a manner that with an input signal attenuation following this characteristic, the amplitudes of the attenuated echo signals are approximately proportional to the return cross-section of the reflecting object. This allows an at least coarse classification of the type of target.

Patent DE-3403197-A1 (DE)
Title: Shelter filter for air-raid shelters
Inventor: BOETTCHER KURT
IPC: B01D46/00
Filed: 1984-01-31
Abstract: The shelter filter for air-raid shelters is intended to purify air, in the ventilation installation, in particular air which has possibly been ABC-contaminated. For this purpose, the filter has a particulate filter and a downstream gas filter. In order to supply air-raid shelters with normal air and simultaneously protect the filter material, the said air is channelled in a bypass line past the shelter filter or through an intermediate piece which has been inserted in place of the shelter filter when the latter has been removed. Changeover to ABC-protection requires changeover via valves or else exchange of the intermediate piece for a shelter filter. The shelter filter according to the invention contains the ABC-part and the bypass part in a housing and separated from each other by a partition. Each part has the same connecting pieces for the supply and discharge of air. In order to change over the ventilation option, after the connecting pieces have been detached, the housing only has to be rotated through 180 DEG  and then attached again. Only the shelter filter is required which, incorporated in the ventilation installation, is held ready and available.
Patent DE-3417282-A1 (DE)
Title: Compressed air generating unit with ozone accumulation chamber
Inventor: FRENKEL WALTER
IPC: A61H33/02
Filed: 1984-05-10
Abstract: In order to increase the ozone yield of a compressed air generating unit for an air bubble bath device, the ozone combustion tube (2) inside the blower (10) is surrounded by an ozone accumulation chamber (1) consisting of a protective hood (1a) and a plate (3). The air (9) drawn in by the compressed air generating unit (6) is sucked through the ozone accumulation chamber (1) and fed to the air distributor (11) in the tub (13) via the feed hose (8). The ozone formed on the ozone combustion tube (2) is thus no longer in contact with spark-forming parts or rubber-containing material inside the housing (10) where it would be destroyed and could in turn lead to corrosion, but instead it is quickly removed from its formation site due to the eddy produced by the compressed air generating unit (6), so that there is less chance for it to decompose again to oxygen before entry into the bath water (14). The ozone yield and the durability of the device components are increased as a result. <IMAGE>

Title: Process for producing coal briquettes and equipment for carrying out this process
Inventor: MUELLER WERNER
IPC: C10L5/08
Filed: 1984-07-12
Abstract: The invention relates to a process and to equipment for producing coal briquettes from lignite and bituminous coal, wherein the constituents of both types of coal are mixed, heated and pressed to briquettes and then cooled. The invention is based on the object of providing a process of the type described at the outset, which does not require a binder for briquetting, avoids odour nuisances and, with a very low sulphur content far below the emission regulations, makes it possible to dispense with heating of the mixture before the pressing step. According to the invention, this object is achieved essentially by removing the moisture from the lignite by preliminary pressing, mixing it only after this with the bituminous coal and then pressing this mixture without a binder under high pressure through a pellet matrix, the emerging pellets being heated by frictional forces with partial removal of moisture and then being cooled. <IMAGE>

Title: Fuel injection pump for internal combustion engines
Inventor: BAUR KLAUS DR
IPC: F02M41/12
Filed: 1984-08-08
Abstract: A fuel injection pump for internal combustion engines has a pump piston (10) guided in a pump cylinder (12), which piston defines a pump working chamber (13). During the delivery stroke the pump working chamber (13) is connected to an injection nozzle assigned to a cylinder of the internal combustion engine. A control slide valve (26) displaceable on the pump piston (10) opens a relief aperture (29) in the pump piston (10), connected to the pump working chamber (13) at the end of the delivery stroke. In order to prevent fuel being blown back from the injection nozzle into the pump working chamber (13) immediately at the end of the delivery stroke when the nozzle needle is not yet closed, the relief aperture (29) is closed by a pressure control element (31), which at least at the start of the opening of the relief aperture (29) maintains a predetermined pressure in the pump working chamber (13) and in the fuel injection line (22) by means of the control slide valve (26).

Title: Partition wall, comprising PVC hollow-chamber profiles, for the flexible subdivision of sports halls and other areas
Inventor: KACZIKOWSKI DIETMAR
IPC: E04B2/82
Filed: 1984-10-24
Abstract: In order to improve the sound insulation in the case of a flexible partition in sports halls and other areas, PVC hollow-chamber profiles are suspended horizontally from the ceiling and are horizontally connected by means of Trevira fabric or the like. Furthermore, the necessary number of profiles are fitted together in order to fill the entire width of the area. A partition wall is thus obtained which has excellent noise-insulating values and which can also, if required, effectively subdivide relatively large areas, e.g. sports halls having a hall cross-section of 27 x 7 m. The service value of, for example, sports-hall partitions is thus substantially increased. Furthermore, costs for expensive additional equipment such as, for example, sound-absorbing installations can be eliminated by using these partition walls. Even where flower-auctioning halls are concerned, energy costs can be cut down since partitioning of the individual halls in terms of temperature is more effective than that provided by artificial-leather pleated curtains.
