Title: Drive station for elastic conveyor belts
Inventor: PRUNER JOSEF
IPC: B65G23/12
Filed: 1983-02-22
Abstract: The invention relates to a drive station for elastic conveyor belts in which the conveyor belt runs over three drums, two of which are mechanically coupled to one another and act as drive drums and one of which acts as a deflection drum. In known embodiments of this kind of drive station, individual drive drums are subject to wear and the lifetime of the conveyor belts is in many cases unsatisfactory. In order to avoid the disadvantageous wear of conveying drums, the incoming conveyor belt is first guided over a first driven conveying drum (1), then over a non-driven deflection drum (2) and only after that over a second driven conveying drum (3). In this process, the conveyor belt only touches the two driven drums (1, 3) with its underside, which is not intended for transport. <IMAGE>

Title: Process for treating, in particular with gases, viscous materials, such as liquid manure, slurry or the like
Inventor: SIEFKEN MARTIN
IPC: C02F3/24
Filed: 1983-09-14
Abstract: In order to avoid, in particular, putrefaction in viscous materials subjected to decomposition processes, such as liquid manure, slurry or the like, such materials are treated by a process in which the material is withdrawn from the container and passed through a closed chamber containing the gas whose concentration is to be increased. During this, gases given off by the material, in particular ammoniacal gases responsible for the fertilising value because of the nitrogen content, are passed into a scrubbing station through which flows a scrubbing substance. At the same time, the material in the chamber is disintegrated into very fine fractions increasing its surface area, improving the gas uptake, for example the oxygen uptake. The scrubbing substance more or less saturated with gases taken up is again admixed with the material enriched with oxygen leaving the chamber and the mixture is returned to the container. The process thus proceeds in a circulation.

Title: Process for heating a film web of a thermoplastic having a distinct crystalline melting point
Inventor: KIEFER GUENTHER
IPC: B29C51/42
Filed: 1983-09-24
Abstract: The invention relates to a process for heating a film web of a thermoplastic having a distinct crystalline melting point, for example polypropylene or corresponding composite films. In the process partial regions of the film web are brought to different temperatures. In order then to be able to deform the regions to be deformed at a temperature above the crystalline melting point, without any problems occurring thereby by cutting - dragging of the material into the cutting gap -, it is proposed to keep the cutting-line region at a temperature below the crystalline melting point. By this means there are no cutting problems. The material outside the cutting-line region can preferably have the same temperature as this region or a lower temperature. <IMAGE>

Title: Operating device, especially for a lift truck brake device
Inventor: BAUMANN MANFRED DIPL ING
IPC: B66F9/06
Filed: 1983-11-17
Abstract: The operating device proposed especially for a brake device on a driverless lift truck or the like operates as a function of the speed of travel of this lift truck. At low speed at a predetermined point the brake of the lift truck is not operated, whereas in the event of too high a speed a braking process is triggered by this operating device in order thereby to prevent the lift truck from running into a wall or some other obstacle. For this purpose it is necessary, for example, that along the route at a predetermined distance from the wall or the end of an aisle between two high shelves (4) a cam (11) or some other obstacle to be run into be fitted on the floor for a swivellable operating element (5). If the operating element (5) is swivelled slowly, the medium, especially a liquid, contained in a working cylinder (7) flows off slowly by way of a restrictor device (22), whereas if the operating element (5) is rapidly operated the restrictor device (22) does not permit this flow rapidly enough. Consequently lifting of the operating element (5) causes a displacement of the entire working cylinder (7), which then acts on an operating member (28) of a brake device of the lift truck or the like. <IMAGE>

Title: Information reproduction system
Inventor: KURODA KAZUO
IPC: G11B20/06
Filed: 1983-12-27
Abstract: A system for reproducing an item of recorded information, in which an item of audio information is contained, is disclosed. An item of audio information in the reproduced information is converted into an audio signal which is passed to a low-pass filter in which its higher band component, which contains the high band of the audio frequency range, is attenuated. The signal drop-out, if any, of the attenuated output of the low-pass filter is compensated. The high band of this compensated output is boosted and equalised, in order to compensate the high band component of the audio frequency range which was attenuated by the low-pass filter.

Title: Transverse filter echo canceller for long acoustic echoes
Inventor: SAUERBURGER HEINZ DR ING
IPC: H03H21/00
Filed: 1984-08-24
Abstract: The feedback occurring between a loudspeaker and a microphone, in particular in hands-free and loudspeaker systems, is intended to be suppressed by adaptive transverse filters. Due to the long reverberation period of acoustic echoes, a transverse filter would be required for this purpose with so many coefficients that adequate adaptation to changing acoustic conditions would not be possible. To reduce the number of interdependent coefficients, the speech band, following conversion into speech samples with the sampling period T, is divided into M sub-bands with the same bandwidth and in each sub-band the sampling period T is increased through sampling rate conversion to T1 = T . M, M transverse filters, decoupled from one another and in each case having a lower number of coefficients, are used instead of a transverse filter with a multiplicity of coefficients, so that the total required number of multiplications with constantly changing coefficients is reduced by the factor 1/M. Use in amplification and studio systems and for frequency bands greater than the speech band is also advantageous. <IMAGE>

Title: Prevention of encrustation in evaporators in which waters containing SO4 and Ca ions, such as seawater or the like, are evaporated after removal of sulphate
Inventor: VAJNA SANDOR DIPL ING CHEM DR
IPC: B01J49/07
Filed: 1984-10-15
Abstract: SO4 ions are exchanged for Cl ions in waters which also contain NaCl and Ca ions, e.g. seawater or the like, in order to prevent the precipitation of CaSO4 during concentration. The concentrate of the evaporator is generally used for regeneration. However, it has been shown that in this process, the sulphate ions increase on the exchanger so that they are also contained in the concentrate. Since this is used again for regeneration, the residual content of sulphate on the exchanger further increases. However, a great number of exchange cycles at the beginning of operation in a plant does not lead to precipitation of the CaSO4. In the present process, the ion exchanger used in this case was reactivated before the solution to be processed became saturated with CaSO4, i.e. it is treated with a regeneration solution prepared outside the described circulation of the solution, by which regeneration solution the accumulated amount of sulphate ions is substantially removed. In the subsequent cycle, a solution treated by the ion exchanger is obtained once more from which no CaSO4 precipitates even during concentration. The regeneration solution used for activation can be prepared in three different ways.
