Patent DE-3445159-A1 (DE)
Title: Stripping and cleaning device
Inventor: PETERSON UWE DIPL ING
IPC: B29C37/00
Filed: 1984-12-11
Abstract: The invention proposes a stripping and cleaning device for moulding presses and injection moulding machines which strips the produced parts, made of rubber, plastic or similar materials, and also cleans the mould itself, the cleaning elements being in the form of elastic, for example rubber, strips which are mounted on roller-shaped carriers. This prevents the thin-walled flash adhering to the mould surface being stripped and sticking between the groups of bristles, just as relatively large parts, for example O-rings, are prevented from catching between the groups of bristles and thus resulting in production of rejects. The same applies for the catching of thin sprue webs between the bristles of the brush and the rapid wear of the brushes and of the mould surface due to the friction effect of the brush.

Patent DE-3535297-A1 (DE)
Title: Conveying installation for coathangers
Inventor: LARSEN MOGENS ERUP
IPC: B65G47/61
Filed: 1985-10-03
Abstract: A conveying installation for coathangers, to or from which clothes are to be attached or removed and which comprises a frame (4) having a conveying device (5) for the coathangers, a releasing device (6) for individual delivery of the hangers to the conveying device (5) and a transferring device (7) which transfers the hangers on the conveyor device to a further conveying device (8) and in which an appliance (9) for individually holding the coathangers is attached between the releasing device and the transferring device. The conveying device (5) is an endless conveyor belt with hanger carriers attached at intervals, and the conveying device is stopped when the appliance (a) for holding a coathanger is activated. The coathanger thus hangs immovably fixed and steady while the operating person hangs clothes on the hanger or removes clothes attached to the hanger. The handling time is thus substantially reduced, since the operating person concerns himself only with hanging items on the hanger or removing them from the hanger and does not have to hold the hanger still or attach it. <IMAGE>
Patent DE-3536673-A1 (DE)
Title: Process for drying gases
Inventor: SCHIMONEK HELMUT
IPC: B01D53/26
Filed: 1985-10-15
Abstract: In the process for drying gases, cooling of the gas is carried out as far as the desired dewpoint temperature beneath the freezing point of water in order to remove moisture. During this, the gas is brought into direct thermal contact with a liquid which must be able to mix with water without freezing in the deep cooling range up to a certain mixing ratio. The cooling of the liquid is carried out with the aid of a refrigeration machine equipped with an on/off controller. Depending on the type of the refrigerator, the gas to be cooled can, as in Fig. 1, be bubbled directly through the cooling liquid or, as in Fig. 2, water can be passed as spray mist through the air. In both apparatuses, moisture is separated out from the gas, which moisture mixes with the liquid and dilutes this. It is therefore necessary to replace the diluted liquid from time to time by undiluted liquid. The process operates particularly economically if the water situated in the liquid is again evaporated after withdrawal. As a result, only the liquid is circulated and does not need to be continuously replaced. The process operates up to a pressure dewpoint of -15/-20 DEG C considerably more cheaply than the process of adsorption drying previously applied. There is a great need for such plants in industry.

Patent DE-3607520-A1 (DE)
Title: Process and device for anaerobic waste water purification
Inventor: VOIGTLAENDER GOTTFRIED DR SC T
IPC: C02F3/10
Filed: 1986-03-07
Abstract: The invention relates to a process and a device for anaerobic waste water purification. It can be employed in the biological purification, with the aid of anaerobic microorganisms, of waste water (effluent) containing organic impurities. The aim of the invention is a considerable increase of the purification capacity of anaerobically functioning small-scale sewage treatment plants with the tank volume remaining the same. The increase of the purification capacity is to be achieved without additional energy consumption. The technical object of the invention is the increase of the biomass available for the anaerobic degradation of the organic impurities contained in the waste water. The object is achieved by introducing according to the invention support material, for colonisation by anaerobic microorganisms, into the digestion space. The biomass available for the degradation of the organic impurities is increased, taking into consideration the concentration-dependence of the reaction velocity of biological processes, in such a way that the same degradation capacity is always achieved in the entire digestion space through which the flow passes. The device according to the invention, in which woven material is preferably used for additional colonisation surfaces for anaerobic microorganisms in the digestion space, is characterised in that the additional growth surfaces for the biomass are built into the digestion chamber alternately at two different depths.
