Title: Dust gas filter
Inventor: MARGRAF ADOLF DIPL ING
IPC: B01D46/48
Filed: 1982-03-25
Abstract: A flue gas purification plant is composed of a plurality of dust gas filters connected in parallel, the filter elements of which are cleaned from time to time, in which the particles falling downwards are fed to a common dust transport device, with the aid of which these particles are transported to an area of the raw gas line in which the newly arriving flue gas flows through one or more spherical rotors arranged in parallel and as a result the particles returned from the filters are collectively fed again with the flue gas to the filter elements. The quantity of particles circulating in the system is limited by removal of a part-quantity of particles at an appropriate position for this, so that after a settled state has been attained, a stable equilibrium is inevitably established with respect to the quantity of particles circulating.

Title: Travelling formwork for casing-concrete walls
Inventor: WEBER HILAR
IPC: E04G17/12
Filed: 1982-10-16
Abstract: Although disposable casing-concrete formworks made of insulating materials, in particular of rigid foam boards of the lower weight class, are optimally heat-insulating, they are unsuitable as a concrete formwork. These insulating-material formworks are able to offer only insufficient formwork resistance to the high pressure of a fresh concrete mass moved by pouring and vibration. Formwork bulging or formwork fractures can be prevented in this case only if the core concrete is delayed and poured in in small portions. To be able to fill such a soft casing-concrete formwork to wall height at least in two passes - and hence to make it also industrially usable - a dimensionally limited hard formwork unit (travelling formwork according to the patent description) displaceable laterally on rollers is placed over it. After it has resisted the main pressure of the core concrete mass, produced by the filling and vibratory movement, the travelling formwork unit can move on with the filling point, since the soft casing formwork uncovered again thereby is now able to withstand on its own the much lower pressure of the core concrete mass now at rest. A further advantage of the invention is to be seen in that the loading weight of the travelling formwork presses the light casing-concrete formwork down so that it is unable to "float up" during concreting. In this process, the horizontal casing joints are also pressed together so that, even in the case of any subsequent post-shrinkage of the boards, no ... Original abstract incomplete.

Title: Process for preventing unnecessary energy losses in the ventilation of a room
Inventor: WIEDENFELD HELMUT
IPC: G05D23/275
Filed: 1982-12-11
Abstract: Energy-saving measures, in particular in the case of expensive heat energy, are not yet exhausted. The energy released from heated rooms during ventilation escapes unused. Thermostats even call for increased energy feed as a result of the temperature reduction which consequently has the effect that energy escapes unused to a greater extent. This is to be avoided by cutting off the energy supply during opening of ventilators of all types, the opening being monitored and the switching pulse carrying out a forced cutoff of further heat energy. To carry out this task simply, safely and economically is the aim of the invention, in order that as many heating installations as possible can be fitted and retrofitted therewith. An application in refrigeration technology can be derived from the solution principle. <IMAGE>

Patent DE-3308190-A1 (DE)
Title: Process for producing a halftone image having changed contours, starting from an original halftone image
IPC: G03C5/08
Filed: 1983-03-08
Abstract: In this process, a halftone negative and a halftone positive, which have exactly the same image size and sharpness and have been exposed and developed in the same density interval of the gradation curve, are produced from the original halftone image. This halftone negative is fitted congruently over the halftone positive and used for producing a contour film. The exposure is here carried out in such a way that the light predominately penetrates at the density changes. The final image, which especially is a halftone image, is prepared from the contour film thus obtained, which has no image gradation, with a desired density interval from the film image produced from the original halftone image.

Title: Process and equipment for removing dust from coking plant emissions
Inventor: STOG WILHELM DIPL ING
IPC: C10B33/00
Filed: 1983-04-30
Abstract: The emissions released during coke pushing in coking plants are discharged through an extraction line laid parallel to the coke oven battery and introduced directly into the quench tower and dedusted therein by means of the existing quench nozzles and the quench tower spray. During the initial phase, that is to say the first half period of the quenching step, 2 to 3 times the quantity of quench water as compared with the end phase or the second half period is sprayed into the quench tower. The quench tower thus serves successively for quenching the red-hot coke and, on the other hand, for removing dust from the flue gases released on coke pushing. For this purpose, the quench nozzles are arranged and designed in such a way, especially pointing vertically upwards, that they can be changed over to intensive spraying by means of a control valve. The introduction of the extraction line into the quench tower ensures that the flue gases are introduced into the quench tower uniformly and at reduced velocity. <IMAGE>
