Title: Contaminated wood-surface cladding sheet - forms airflow space moving pollutant molecules, for absorption
Inventor: GERISCH ROLF
IPC: A62D3/00
Filed: 1992-02-19
Abstract: The sheet forms cladding for wood or chipboard surfaces contaminated with chemicals such as formaldehyde, pesticide, fungicide, insecticide etc. to remove them. High- or low-pressure polyethylene or polypropylene sheet is pulled over the cladding to form an intervening space, through which a current of air generated by a pump flows. This moves the emitted pollutant molecules. These react chemically on the sheet inside surface and are absorbed. Dependent on the type of chemical, the air can be heated or humidified beforehand. The air can escape via a micronic filter. ADVANTAGE - Rapidly ends gas emission

Inventor: WAGENER PAUL-WERNER
IPC: B61D39/00
Filed: 1992-06-26
Abstract: The invention relates to a railway goods wagon with an underframe (5) which is borne by sets of running gear and has an essentially level loading platform (1) and longitudinal beams (6) which are constructed as fish beams in the region between the sets of running gear (7), and the loading space is bounded by end walls (2) which are permanently connected to the underframe (5), a roof shell (3) and side walls which consist of sliding wall components (4), which can be displaced and swivelled out, or by raisable, swivelling-out entire wall components which can be displaced one on top of the other and form the roof and the side walls. The object of the invention consisted in finding a possible way, for a railway goods wagon of the type mentioned at the beginning, of using the sliding wall components and entire wall components, which bound the loading space, to transmit horizontal and vertical forces in the closed state of the railway goods wagon. This object is achieved in that the sliding wall components (4) or the entire wall components, in the closed position, are clamped at their end wall-side longitudinal ends at the top in their vertical region to the end wall (2) and at their longitudinal end facing the longitudinal centre of the wagon are clamped at the bottom to the underframe (5) in a positively engaging fashion and the sliding wall components or entire wall components are constructed in their vertical area between the clamped attachment to the end wall (2) and the clamped attachment to the underframe (5) so as to transfer tensile forces and pressure forces. <IMAGE>
Patent DE-4220947-A1 (DE)
Inventor: DREWS MANFRED PROF DR
IPC: C05F7/00
Filed: 1992-06-26
Abstract: The hitherto conventional standard method of direct field application of liquid manure and slurry is burdened with a number of disadvantages such as primarily environmental pollution in the form of odour emissions, giving off ammonia gas and nitrate seepage, as well as high capital expense for the storage and application technology. In the case of domestic sewage (effluents), collection in central sewage treatment plants causes high costs with unsolved disposal problems for the residues. The novel composting process according to the invention is intended to overcome these disadvantages and to be an economically profitable alternative. Slurry, liquid manure and sewage are pumped from a collection pit or vessel (1.0 in the figure) into a fermentation and drying tower (2.0), directly after their production and are discharged centrally above the transport pallet (2.2) filled with wheat straw. The thin slurry dripping off with evaporation of water and leaving behind coarse components is withdrawn via a drain (3.1), incorporated in the floor, into the filtrate vessel (3.0). From there, it is forced via a suction and pressure pump (3.3) to a spray nozzle in the upper tower part (2.3). The spray drops descending in the ascending air stream release water, moisten the compost pallet with their residual water content and return as excess into the filtrate circulation. The ascending air stream escapes (2.4) at the roof via a demisting orifice. The air intake for oxygen supply and drying proceeds from a solar warm air collector (4.0). The result is a compost which is further dried in the tower to below 30% residual water content for loss-free storage. The process is suitable for all animal husbandry businesses and households in an isolated situation instead of conventional disposal methods; because of its low capital expenditure, it is especially suitable also for small-scale businesses. <IMAGE>

Title: Measurement and control for electronic two-point or proportional controller - involves varying control dead period according to change in actual value between control cycles
Inventor: STUHL MANFRED
IPC: G05D23/19
Filed: 1992-08-10
Abstract: The method involves a dead period during which the measurement sensor cannot influence the actual value parameter. During a control period the measurement parameter influences the actual value and is controlled towards the desired value. After the expiry of the variable dead period the difference between the current actual value and the actual value at the end of the previous dead period is determined. Its ratio to the switching difference of the two-point controller is determined and the dead period for the next cycle varied accordingly. USE/ADVANTAGE  - E.g. for controlling temp., humidity or pressure when using electric heating equipment, e.g. storage heater. Method eliminates some problems encountered with conventional methods, including their expense.

Title: Method for generating harmonic colour corrections in a colour space, in particular CIELAB colour space
Inventor: DORFF PETER
IPC: G03F3/08
Filed: 1993-12-18
Abstract: Method for generating harmonic colour corrections in a colour image. The colour image is stored in an image memory and shown on a monitor. Using a coordinate entry device, colour samples, which are intended to be of those colours subjected to a selective colour correction, are taken from the image. Colour correction values, which act on the colours determined by means of the colour samples, are entered. In order to obtain harmonic transitions at those locations in the image where the selected colours encounter the non-selected neighbouring colours, the colour correction reduces towards the edges of the colour correction region. This is achieved by means of filtering the colour samples or colour correction values. A colour computer calculates the corresponding colour correction values. <IMAGE>
