Patent DE-4217666-A1 (DE)
Title: Filter assembly - has candle-shaped filters on an intermittent rotating plate to increase the filter density
Inventor: KUEHME ERNST DIPL ING
IPC: B01D29/39
Filed: 1992-05-28
Abstract: The filter assembly, to separate solids from liquids, has a number of candle-shaped filters fitted to a rotary plate which is turned in steps, within a pressurised filter housing. The outlines (32,33) of the filters, arranged in order (1'-12'), converge towards the centre of the rotary plate. The filtrate take-off (9) is at the peak of the converging lines (32, 33) of the filter outlines. The converging edges (32,33) of the filter outlines are joined by a rounded curve, which partially surrounds the filtrate take-off tube (9). The other ends of the filter outline, away from the plate centre, are joined by a straight line completing the filter outline shape, or they are joined by a roof-shaped angle (34,35). A filter unit housing has an axial movement above the fluid level in the filter housing which, on rotation of the plate, releases a filter in its position (1'-12') and covers it on a further rotation of the plate. The cross section line of the filter unit housing is generally parallel to the cross section lines of the filter cross sections. The filter unit housing, in the direction of rotation, is after the station where the retained solids are removed, and the filter is repeatedly immersed in the fluid to be treated, after a filtering action to prepare the filter medium. The filter unit housing provides pre-coating of the filter medium by rinsing in a fluid pre-coating, through a fluid inlet and outlet switched into operation alternately. The fluid inlet ends in a wide-slit jet over the fibres, with a jet stream covering the filter lengths. The filter housing has a two-part cover with a concentric inner cover to carry a rotary bearing for the plate shaft and a suspension for the shaft control disc, and the shaft is secured at its lower end in a holder at the base of the housing. This gives an opening for the insertion and removal of the filters. The retained solids are removed at a compressed air lock, with a climbing conveyor in a pressurised encapsulation between the lock and filter housing, to carry the material to an ejection point over the lock. USE/ADVANTAGE - The filter assembly is a pressure filter for technical fluids, to separate solids from the liquid such as for treating process water with water cleaning. Through the filter shape, more filters can be fitted to the rotary plate, with simple removal of the retained solids and filter change while other filters are in use.

Title: Method for determining reference variables for process systems, especially for a process controller
Inventor: ROGOS JUERGEN DR ING
IPC: G05B17/02
Filed: 1993-02-08
Abstract: The invention relates to a method for determining reference variables for process systems. In the case of complicated processes, their control can be impaired by the envisaged reference variable(s) not being sensitively dependent on different process states. In order to avoid this point of weakness, according to the invention, numerical simulations are carried out, in that the envisaged reference variables are calculated approximately as a function of the process state and/or in their course with time during the process and at various locations in the process space. Thereupon, the dependence of the individual reference variables on the process quality is determined. Then, by means of a comparison, those reference variables are determined for which the largest changes in terms of amount have occurred during the running time of the process. <IMAGE>

Title: Detachable plug connection
Inventor: HEZEL BRUNO
IPC: H01R13/629
Filed: 1993-03-06
Abstract: A detachable plug connection for a plurality of electrical contacts (14) is to be designed such that the contacts (14) can be joined together and detached parallel to their longitudinal course. For this purpose, a locking device (13) is connected to the plug parts (11, 12) of the plug connection, which locking device (13) consists of a locking lever (16), a deflection lever (18) coupled to it, and two supporting bearings (19). When the locking lever (16) and the deflection lever (18) which is driven by it are rotated, the two of which are mounted on one of the plug parts (11, 12), pivoting shafts (27, 37) (which are fitted to the ends of the two levers (16, 18) and move in the same manner) enter supporting bearings (19) which are fixed on the other one of the plug parts (11, 12). In consequence, the position change of the two levers (16, 18) is transmitted to one plug part (11) such that its position change takes place parallel to the longitudinal direction of the contacts (14). <IMAGE>

Title: Process for producing sulphuric acid
Inventor: KLEMM MARCO
IPC: C01B17/74
Filed: 1993-03-25
Abstract: The production of sulphuric acid from the SO2 in flue gases and similar waste gases by conventional processes has numerous problems, in particular     - high losses as a result of side reactions   - round-about route via SO2-enriched gas   - problems with impurities   - low degree of removal of the SO2 from the flue gases   - only sulphuric acid of low concentration can be prepared   - expensive chemicals required.  The process is to alleviate these problems. Sulphuric acid is produced by the decomposition of ammonium sulphate, particularly from flue gas purification. The ammonium sulphate is first decomposed into ammonium hydrogen sulphate and ammonia, then the hydrogen sulphate is decomposed into water and ammonium disulphate (pyrosulphate) and this is subsequently decomposed into ammonium sulphate and sulphur trioxide. This is reacted with water to give sulphuric acid. Desulphurization of flue gases with simultaneous production of SO3 or sulphuric acid. <IMAGE>

Title: Method for bending
Inventor: BUCHOLD HELMUT DIPL ING
IPC: B21D7/14
Filed: 1993-04-17
Abstract: The method is employed for bending tubes for use where high accuracy is required, e.g. in the aeronautics and aerospace sector. A tube section is first of all provided with a predeterminable length and the tube section is then provided in the region of a numerically controlled bending device with a predeterminable bend curve. A comparison of the bend curve produced with a desired curve is then performed, at least by way of sampling. The tube sections are configured to a predeterminable final length dimension before bending. Before a series bending process is carried out to produce a plurality of tube sections bent in the same way, a bending parameter input for the bending device with a desired parameter set is loaded. The desired parameter set after measurement of spring back is modified as a function of bending curves from test bends which are measured by means of a measuring device, in order to achieve the desired curve. During series production, the modified desired parameter set is used to control the bending device.

Title: Method for processing a dialling digit sequence entered on a telephone PBX system terminal
Inventor: FLEISCHNER ECKART
IPC: H04Q3/76
Filed: 1993-08-27
Abstract: Dialling digit sequences which are entered on terminals and which, at the end of an interdigit monitoring time, have a lower number of digits than the number required for unambiguous dialling evaluation are automatically supplemented to the required number of digits through the addition of leading digits by a telephone PBX system. The method allows, for example, in a PBX system serving as a hotel system, room numbers to be used as telephone numbers, whereby the requirement for the telephone number to comprise n digits can be disregarded.
