Patent DE-3731904-A1 (DE)
Title: Dust-protection device for the machine operator of a selective-cut heading machine
Inventor: BRANDENBURG HELMUT DIPL ING
IPC: E21C35/22
Filed: 1987-09-23
Abstract: Selective-cut heading machines often cannot be equipped with a cab for the machine operator underground during the construction of headings or the driving of tunnels on account of the restricted space conditions. On the contrary, the machine operator on his free seat is exposed to the dust-laden ambient air and is hindered in his work by the dust and also by the temperature prevailing here. It is proposed to provide a protective shield (12) behind the machine operator (13). The outer boundary edge (14) of the protective shield (12) is provided with air slots (15) or with flat jet nozzles (15). The latter are connected to a clean-air line (10) and produce a clean-air flow which runs roughly in the longitudinal direction of the heading, is directed towards the working face (4), envelopes in particular the head and upper body of the machine operator (13) and protects him from the dust-laden ambient air. <IMAGE>

Patent DE-3742738-A1 (DE)
Title: Apparatus and method for utilising wind energy as a wind paddle pump
Inventor: LOHSE DIETER DIPL ING
IPC: F03D5/06
Filed: 1987-12-17
Abstract: The essential feature of the invention is to be seen in using the flow energy over a large area and in diverting it with as high an efficiency as possible into a lifting motion for conveying liquids. This is achieved by means of a streamlined paddle (1) which is fastened on a mast (2) in a centrically rotatable manner (3 and 4), the mast being constructed as a transmission lever and large forces thus being capable of acting on the hydraulic system connected. By means of the resulting pressure, the liquids can be conveyed or pumped to a geodetic height and used as an energy store. If a number of wind paddle pumps is grouped together as a wind park, a relatively large reservoir can certainly be supplied, from which water power stations, water works etc. can be served. Since, however, even one unit can be operated economically, the acceptance by consumers is expected to be high. The method with the associated apparatuses can also be applied to flow utilisation in the sea and in water courses. <IMAGE>

Patent DE-3832913-A1 (DE)
Title: Lifting stage
Inventor: MUELLER CHRISTOPH DIPL ING
IPC: B66F7/06
Filed: 1988-09-28
Abstract: The invention relates to a lifting stage with at least one parallel guide - preferably formed by a scissor linkage - between a base or a bottom part (5, 6) and a top part (12) forming or supporting a platform. Hitherto, a particular lifting stage has always only been suitable for a particular purpose or for a particular range of use. For various purposes or ranges of use, therefore, lifting stages of various size and weight have to be constructed. In contrast, thanks to the invention, lifting stages of different size for loads of different size and weight can be assembled and dismantled quickly and simply from simple, light components or component groups (modules) so that these lifting stages are also easy to transport. For this purpose, according to the invention at least two parallel guides (1, 2, 3, 4) can be releasably connected to one another at the respectively desired distance apart by means of connecting rods (20) of predetermined length arranged transversely to them, and both parallel guides are provided with one drive (10, 11) each, and the drives can be connected to one another by means of a synchronous shaft (25). <IMAGE>
Patent DE-3833432-A1 (DE)
Title: Disposable cartridge having a residual toner container for electrophotographic (electrographic) recording devices
Inventor: FUTHS GUSTAV
IPC: G03G21/12
Filed: 1988-10-01
Abstract: The invention relates to disposable cartridges for electrophotographic recording devices such as copiers or laser printers, which, in addition to a residual toner container (14), have other parts such as loading station etc. which are important for its functioning. Since the additional parts are also removed when the cartridge with the residual toner is thrown away, the environment is burdened (polluted) to a considerable degree, seen from the ecological point of view. The additional parts also add considerably to the price of the disposable cartridge. These disadvantages are reduced according to the invention in that the residual toner container (14) has at least on one freely accessible transverse side a hole (21) which serves as outlet opening for the residual toner and is provided with a thread, and which can be closed in a dust-tight manner by a threaded plug (22) which can be screwed out for discharging the residual toner. As a result, it is possible to use the disposable cartridge several times, leading to a considerably lower pollution of the environment. Since the service life of the other functional parts on the disposable cartridge is utilised in a better manner, this also results in considerably lower copier costs. <IMAGE>
