Title: Cage with a device for locking mine cars
Inventor: SIMMICH KLAUS DIPL ING
IPC: B66B17/22
Filed: 1988-08-25
Abstract: A device for locking mounted mine cars is to be created for a cage. The device is not only to lock pushed-on mine cars absolutely safely and reliably with moderate effort during the shaft transport, it is also to be applicable without problem for mine cars of any, possibly varying, dimensions. Such a locking device comprises clamping beams 5 held essentially parallel to the rails. The clamping beams 5 are held by pivotable levers 9 in such a way that they can be placed around shafts 8 above the top edge of the rails 6 and below the axles of the wheel sets 7 of mine cars against the insides of their wheels. In order to obtain reliable locking during the transport, the free ends of the double-armed levers 9 are preloaded towards one another by means of energy accumulators, for example tension springs 14, so that the free outer surface of the clamping beams 5 or the anti-wear linings 13 applied to them are pressed against the inner surfaces, facing one another, of the wheels. Thus a reliable hold is provided even when the number of wheels of the mine car varies and the wheel spacings of the mine car vary. <IMAGE>

Title: Method for opening a centrifugal separator in a solid-dependent manner
Inventor: LANGER KLAUS
IPC: B04B1/14
Filed: 1988-12-10
Abstract: Method for opening a centrifugal separator in a solid-dependent manner with solid-discharge slots arranged on the periphery of the drum and a piston slide which is controlled in an axially movable hydraulic fashion for opening and closing the solid discharge slot and a solid-discharge system arranged around the drum. A method is described in which the timing of the discharge of the solids is dependent on the depositing of solids and in which the depositing of solids at the time of discharge is determined outside the rotating drum in the solids-discharge system. The value determined in this way is compared with a fixed value predetermined in a comparison device and the comparison value is converted into a control pulse which determines the timing of the subsequent discharge in a memory-programmed control.
Patent DE-3842352-A1 (DE)
Title: Method for operating a moving-bed filter plant and apparatus for carrying out the method
Inventor: OHLMEYER MANFRED
IPC: B01D53/12
Filed: 1988-12-16
Abstract: The invention relates to a method for operating a moving-bed filter plant in which pollutants of a flowing medium, in particular sulphur oxides and nitrogen oxides of flue gases, are adsorbed, the adsorbent, in particular granular activated charcoal or activated coke, first being partly loaded and then again being impinged by the flowing medium for separation of further pollutants. The object of the invention is to arrange the operation of a filter plant of the generic type in such a way that the adsorbent loading is improved and thus the consumption of adsorbent is reduced. The solution of the present invention is that after the partial loading, the adsorbent is removed from the filter plant and temporarily stored before the renewed impingement, a delay time for the adsorbent being maintained for the temporary storage which at least corresponds to the time which the pollutants require after the partial loading to diffuse from the surface into the interior of the adsorbent.

Patent DE-3842941-A1 (DE)
Inventor: KAYS RUEDIGER DR ING
IPC: H04N7/00
Filed: 1988-12-21
Abstract: For future television systems having a higher image quality, it is the aim to change the aspect ratio from 4:3 to 16:9, and it is intended that signals with both aspect ratios will be reproduced in future television receivers. In a television receiver with electron beam tube, up to now it was the deflection which was switched over by the deflection processor to obtain a relative change in the television picture format. This requires a high expenditure of circuitry in the television receiver. To adapt a television picture format generated at the transmitter side and at the receiver side, a time transformation of the video signal is performed by means of a memory arranged in the video signal processor in a television receiver with changed aspect ratio, in which arrangement the visible part of the line is inserted time-compressed into the reproduction raster. Depending on the picture format generated at the transmitter, the reproduction device can be additionally switched over in the vertical direction in the television receiver, the reproduction raster remaining unchanged in the horizontal direction. Future television systems with devices for compatibly changing the picture format. <IMAGE>

Title: Process for purifying gases
Inventor: FECHTER LEONHARD DR
IPC: B01D53/70
Filed: 1989-01-27
Abstract: A novel process is described for purifying polluted gases by means of a circulated absorbtion liquid which absorbs the pollutants. The pollutants are absorbed by the absorbtion liquid by intimate contact of the gases with this and the absorbtion liquid is then regenerated by separating off the pollutants and is reused for the absorbtion of the foreign substances contained in the gases. The pollutants separated off from the liquid are thermally broken down and hydrogenated and then absorbed and neutralised in a scrubbing liquid. As a result the pollutants are converted into harmless substances within a closed process so that intermediate storage and external disposal of the pollutants is dispensed with.

Inventor: KLYNE ULRICH DIPL ING
IPC: C02F3/08
Filed: 1989-03-25
Abstract: In the process, the untreated water is passed through a bed (2) of a buoyant, granular support material, which acts as a support and growth surface for the microorganisms. During the biological degradation process, the interstitial spaces in the support material fill with biomass, which is removed at intervals with the aid of a washing process. To increase the efficiency of the washing process, support material is removed beforehand from the bed (2) with the aid of a jet pump (11), separated from the biomass and subsequently, together with the separated biomass, returned to the untreated water side of the bed. <IMAGE>

IPC: D21B1/06
Filed: 1989-06-15
Abstract: A two-stage method for sorting wood shavings is described, the shavings (17) being fed in the first stage to a gyratory screen (3) and in the second stage to a disc screen (4). The flow of shavings is divided in the first stage into four fractions, the first fraction (18) containing the coarsest type of shavings - mainly oversize shavings - and being fed to a needle cutter (5), from where it flows away in the form of shavings of suitable size and is fed back to the gyratory screen of the first stage. The second fraction (19) contains desired shavings, most of the shavings having excess thickness, and is fed to a stage for screening the thickness. The third fraction (20) consists mainly of desired shavings and is fed to the pulping process, whereas the fourth fraction (21) mainly consists of fine proportions and is fed to a combustion station. In the second stage (stage for screening the thickness), the flow of shavings is divided into two fractions, the coarser fraction (22) of which consists of shavings with excess thickness and is fed via a device for separating stone and metal objects (7) to a shreading machine (12) and is then fed back to the gyratory screen of the first stage, whereas the finer fraction (23) consists of desired shavings and is fed directly to the pulping process. <IMAGE>

Title: Signal stream clock cycle matching - writing bytes of each partial system in respective memory section
Inventor: MAND SIEGFRIED DIPL ING
IPC: H04J3/06
Filed: 1990-06-09
Abstract: In the clock cycle matching the transmission frames contain one or more partial systems, in a byte overlapping manner if several partial systems are used.  The bytes of each partial system are written in a partial region so a flexible memory in a partial region, allocated to the partial system,  for buffer storage. The allocation is actuated by a region counter, controlling the writing and read-out counter of the allocated memory regions according to the byte arrangement in the transmission frame.  Pref. the writing is interrupted, when positive blocking signals appear. The signal is positively blocked when the elastic memory is increasingly discharged during read-out.  Negative signal blocking takes place when the memory is increasingly filled-up in spite of read-out. USE/ADVANTAGE - For SDH operated network, preventing damage to partial system arrangement by simple steps.
