Patent DE-3333992-A1 (DE)
Title: Process for the recovery of metals from used hydroprocessing catalyst particles
Inventor: HUBRED GALE L
IPC: C22B23/00
Filed: 1983-09-20
Abstract: The metals to be recovered are composed of at least one metal of group VIII of the Periodic Table of the Elements and at least one metal of groups Vb or VIb of the Periodic Table of the Elements. The used catalyst particles are initially roasted at a temperature between 400 and 600 DEG C and then contacted with a first aqueous solution of ammonia and an ammonium salt with formation of a first enriched liquid. The once-leached used hydroprocessing catalysts are contacted with a second aqueous solution of sulphur dioxide with formation of a second enriched liquid. The metals from the second enriched liquid are precipitated using hydrogen sulphide and the precipitate is roasted with unroasted used hydroprocessing catalysts. The metals of groups Vb and VIb in the first enriched liquid are transferred into a first organic solution by liquid iron exchange. The first organic solution is stripped by an aqueous stripping solution and the metals are isolated by sequential precipitation. The metals of group VIII are isolated and purified by pure liquid ion exchange.

Title: Electrical toothbrush
Inventor: WALLRATH PETER
IPC: A61C17/26
Filed: 1984-02-21
Abstract: The present invention relates to an electrical toothbrush which makes it possible to remove plaque from the surface of the teeth and from the gaps between teeth and gums by slow, rotating movements and thus to perform optimum oral hygiene complying with the latest findings, which has hitherto been possible only with manual toothbrushes. This is achieved by at least two parallel, rotating fields of bristles which adapt to the anatomical course of the gingival margin and penetrate and clean it at a physiologically acceptable pressure. This prevents pathological changes of the tooth-retaining apparatus and the teeth themselves.

Title: Gulley for a roof, balcony or terrace
Inventor: KESSEL BERNHARD
IPC: E04D13/04
Filed: 1984-11-20
Abstract: The invention relates to a gulley for a roof, balcony or terrace, having an inlet pipe which is enclosed by an insulating edge on which a sealing sheet is fixedly clamped by means of a clamping edge, and having a sealing ring held in an insulating-edge groove on the outer side of the inlet pipe. Owing to the sliding fit which is necessary for adjusting the height of the insulating edge and of the clamping edge with respect to the inlet pipe, water seeps through to the sealing ring in the case of such gulleys used outdoors, this water freezing in the winter, detaching the sealing ring and destroying the sealing effect. This is avoided according to the invention in that an annular groove in which a second sealing ring is located is provided above the sealing ring between the insulating edge and the clamping edge, and in that this second sealing ring can be axially braced by means of the clamping edge and can be radially deformed until it bears against the inlet pipe.

Patent DE-3503695-A1 (DE)
Title: Pneumatic journal bearing
Inventor: KATAYAMA KAORU
IPC: F01D25/12
Filed: 1985-02-04
Abstract: The present invention relates to a pneumatic journal bearing suitable for use for rotating shafts which reach high temperatures during operation, such as, for example, the turbine shaft in a motor-vehicle turbocharger. In these journal bearings, the cylindrical opening in the bearing body has a diameter which is considerably larger than the diameter of the shaft rotating in it. A hollow-cylindrical journal part with an inside diameter which is considerably larger than the diameter of the shaft is arranged coaxially in the bearing opening and attached coaxially to the shaft. Attachment is effected by means of two end plates of the cylindrical journal part. Compressed air is introduced into an interspace between the journal part and the cylindrical bearing surface. Since the cylindrical main part of the journal part is at a distance from the shaft, the journal part does not suffer anything like the thermal expansion which would result in a significant reduction of the interspace, even when the shaft reaches high temperatures. The journal part is preferably provided with a number of through-openings to allow compressed air to be fed into the inner gap and thereby cool the shaft.

Title: Media for detoxifying exhaust gases of industry, of space heating and exhaust gases of motor vehicles
Inventor: BECKER OTTO ALFRED DR
IPC: B01D53/60
Filed: 1985-02-20
Abstract: The invention relates to detoxifying exhaust gases of industry and space heating and the exhaust gases of motor vehicles. It is, in partiular, the object of the invention to prevent the emission of toxic carbon monoxide, toxic nitrogen oxides, sulphur dioxide and hydrocarbons into the atmosphere. For this purpose, the invention provides the arrangement of smouldering substances, preferably carbon, and the entry of air or oxygen and other detoxification-active substances into the exhaust gas pipe (or stack). In particular, gases, for example air, are added to give regulatable temperature and pressure conditions which optimally favour the chemical conversions. In addition, apparatuses regulating room temperature, for example cooling apparatuses which are furnished externally with air or cooling water flowing through, can also be provided in the exhaust gas pipe. The exhaust gas cooling is of decisive importance for the conversion of the toxic carbon monoxide, which originates from the fuels (or from the combustible material), into non-toxic carbon dioxide. This conversion is only possible at temperatures below 800 degrees C. Other detoxifying substances can also be released into the exhaust gases under optimal conditions. Since the individual chemical reactions are independent of each other, the described media for detoxification, when they are not required, can also be individually dispensed with. Only the remaining media listed are then used. Thus can, for example, the ... Original abstract incomplete.

Title: Method for storing and/or transmitting analogue signals in compressed digital form
Inventor: NISSL NORBERT
IPC: H03M7/30
Filed: 1985-03-15
Abstract: An analogue signal (A), the signal range of which can be represented with the aid of m bits, is digitised, only the last n positions being stored so that a compressed digital signal (DS) is present. The digital values of these signals are read out and/or transmitted. If a discontinuity which is greater than the maximum signal change occurs between two successive samples of the compressed digital signal (DS), this is a coding for a change within the positions (n + 1) to m of the digitised analogue signal (A). This coding can be retransformed so that the original analogue signal is obtained by subsequent digital/analogue conversion. In this method, the absolute error is identical over the entire dynamic range and, in addition, the absolute error is not updated. The dynamic range of the signal to be stored is not subject to any restrictions with regard to storage capacity. <IMAGE>
