Title: A process and equipment for compressive regeneration of flexible filter materials, oil separation materials and/or support materials
Inventor: FUCHS UWE
IPC: C02F3/10
Filed: 1981-11-17
Abstract: The invention relates to a process and to equipment for compressive regeneration of flexible filter materials, oil separation materials and/or support materials which are loaded with solids, oil-like liquids and/or bacteria. Especially polyurethane foam has proved to be suitable as such a material. However, its regeneration has hitherto caused great difficulties. It is therefore proposed that the material is transferred into a regeneration device and freed therein by compression from the deposited solids, oil-like liquids and/or bacteria and the water, that the solids, oil-like liquids and/or bacteria, which have been released, are separated from the material by draining together with the water, and the material is removed from the regeneration device. The preferred compression devices used here are either chamber presses or at least two rollers rotating in opposite directions.
Patent DE-3149116-A1 (DE)
Title: Valve for sampling liquid media
Inventor: SCHEIDELER HANSJOSEF
IPC: G01N1/20
Filed: 1981-12-11
Abstract: The invention relates to a valve for sampling a liquid medium in a container, pipeline or the like. The object of the invention is to provide a valve in which the liquid sampling flow only undergoes slight deflections and which, in addition to a simple construction, is remarkable for a self-cleaning effect and can be dismantled and reassembled without using a tool. According to the invention, this object is essentially achieved in that the valve housing (5) comprises two parts (9, 10) which are detachably interconnected, of which one part (9) is associated with the inflow side (2) and is positionally fixed, while the other part (10) is constructed so as to rotate with respect thereto as a rotating element with outflow side (8), a separate valve body (27, 39) being disposed in a cavity (25) which is jointly bounded by the two parts (9, 10) and can be altered by their relative movement with respect to one another, and the essential individual parts (9, 10, 27, 39) of the valve (3) being entirely or at least partly disposed coaxially with respect to one another. Said valve can be used in principle for any liquid medium as a quantity-regulable discharge valve. <IMAGE>
Patent DE-3149271-A1 (DE)
Title: Device for cleaning and/or moistening surfaces or spaces, in particular for peeling off the filter cakes from filter plates in paper manufacturing
Inventor: REITZ ALFRED DIPL ING
IPC: B05B15/52
Filed: 1981-12-12
Abstract: In a device for cleaning and/or moistening surfaces or spaces, for precipitating dust or foams, in particular for peeling off the filter cakes from filter plates in paper manufacture, pipe branches start from a spray liquid feed pipe and serve to hold spray cans which apply the liquid to the object to be cleaned or moistened. A cylindrical housing is releasably attached to the connection part of the pipe branch, which serves to feed the liquid, in the manner of a T-element and has a radial recess in which a nozzle having a widened portion is arranged in such a way that the nozzle outlet located at the apex point or approximately at the apex point of the widened portion projects into the interior of the cylindrical housing. The cylindrical housing is penetrated axially by a manually operable cleaning device for the nozzle outlet. By means of such a device it is possible to clean individual contaminated or blocked nozzles without the entire system having to be shut down for this purpose. The contaminated or blocked nozzles remain in their mounted position during the cleaning process. Since as a result of this the outage times of the entire system can be virtually reduced to zero, it is now possible to a very large extent to dispense with the expensive fresh water which was used previously to a certain extent and with the equally expensive systems for cleaning and processing circulation water. Instead, the unrestricted use of circulation water containing impurities is possible.

Patent DE-3209926-A1 (DE)
Inventor: HOELZER HELMUT DIPL ING
IPC: F16J15/3224
Filed: 1982-03-18
Abstract: A radial shaft seal ring has a lip ring for sealing to a shaft for rotation therewith. A U-shaped recess extends around the lip ring. An extension portion of a reinforcing ring which delimits a space on one side thereof to be sealed contacts the U-shaped recess without pressure or connection for low wear relative rotation therein. Preferably, the shoulder of the lip ring defining the side of the U-shaped recess on the sealed-space side of the reinforcing ring has a greater outside diameter than that on the other side to centrifugally aid the seal. More preferably, the latter is done by angling the U-shaped channel to the sealed side to also accommodate axial vibration of the shaft and lip ring.

Title: Vacuum-switch/contact arrangement having a device for generating an axial magnetic field
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/664
Filed: 1982-07-22
Abstract: In a vacuum switching container, an axial homogeneous magnetic field is generated by means of an energising arrangement which is combined with the switch pieces which can move relative to one another. The energising arrangement is constructed using a comparatively reduced number of components. This novel design has the following characteristic features: centrally-symmetrical spokes originate from first and second supporting bodies which are constructed as round rods. Complex winding formers are attached thereto. At the ends, the winding formers expand to form contact and electrode surfaces. The contact and electrode surfaces of in each case one winding former are superimposed on the first and second supporting bodies, and the circular-arc sections originating from the superimposed region represent parts of an energising winding. It is also essential that the contact and electrode surface of a first winding former are at least partially surrounded by the circular-arc section of the subsequent winding former.

Patent DE-3230010-A1 (DE)
Title: Apparatus for self-induced circulation of digesting biomass
Inventor: IWAN KLAUS
IPC: C02F3/28
Filed: 1982-08-12
Abstract: The object of the abovementioned invention is to circulate biological digestion sludge in vessels, to be precise without externally supplied energy. As is known, for the optimal digestion of biological waste, the particular biological digestion sludge must be set in motion. This has conventionally been carried out hitherto by the use of electrical energy. The present invention has demonstrated the possibility of circulating the liquid by the internally produced gas pressure. This possibility is achieved in terms of process and construction by the biological liquid being transported to and fro within a vessel using the internally produced biogas pressure. As a result, the entire apparatus, that is the digestion vessel, is set in motion, which represents one of the essential novelties. The sludge, that is biological digestion sludge, is only set in motion and circulation by this motion of the vessel. It is thus possible to optimise the digestion of biological waste by this method, and in fact without the use of the energy required hitherto for this purpose. According to the accompanying diagram (Figure 3), such a vessel stands on a rocker situated centrally underneath. The right chamber (No. 10) is separated from the left chamber (No. 12) in that the gas spaces are not connected together. When the gas pressure rises in space (10) this forces the liquid located underneath through chamber (11) and channel (8) into the opposite vessel part (No. 14). In accordance with Figure 4, the vessel standing on the rocker (6) then tips over to the left side. If the sludge has not already been transported to the left vessel side by the gas pressure, liquid now additionally flows through the channels (No. 7 and 8) into the opposite vessel side. The same procedure is repeated such that the gas pressure rising in the gas space (12) on the left side now forces the liquid back to the right side of the vessel. This now tips again to the right and the liquid transport and liquid circulation are repeated. <IMAGE>

Title: Swivel-jointed tractor unit
Inventor: GEBHARD OSKAR ING GRAD
IPC: B62D7/14
Filed: 1983-06-01
Abstract: The invention relates generally to detachable road train combinations and in particular to the cessation of the differential movement which until now has been customary of the driver's cab of the tractor unit and the semitrailer body when driving off-road and cornering. By virtue of the cessation due to the invention of these differential movements the safety and movement clearances which have until now been necessary can also be dispensed with which, with the same tractor-unit dimensions, introduces the economic advantage of increasing the payload space including the possibility of loading and unloading at the ends. This is achieved in the swivel-jointed tractor unit according to the invention by virtue of the fact that: the swivel-jointed tractor unit has a special coupling frame which is fixed on the tractor-unit chassis, and is mounted movably, in such a manner that it can receive the tractor-unit driver's cab and, at the same time, serves as a coupling and guiding part for the semitrailer, the tractor-unit driver's cab being connected and coupled in terms of movement to the coupled-up semitrailer via the special coupling frame.
Patent DE-3323320-A1 (DE)
Title: Protection of a semiconductor controller with a downstream-connected converter transformer against excess current resulting from the occurrence of single-sided magnetisation of the converter transformer
Inventor: REUSCHEL KLAUS ING GRAD
IPC: H02M3/337
Filed: 1983-06-24
Abstract: A semiconductor controller with a downstream-connected converter transformer is protected, without the fuse which is connected upstream of the semiconductor controller triggering, against the occurrence of an excess current in the event of interruptions in the input AC voltage (UN) in that two immediately successive half-cycles of the input AC voltage are detected via a measurement transformer (1) and their voltage/time integrals are compared with one another. This is done by means of two integrators (2, 3) which supply the measurement voltages which are proportional to the voltage/time integrals to an element (4) which forms the difference between the two measurement voltages. If the difference between the two measurement voltages exceeds a value which is predetermined by a window comparator (5) a locking device (9) for the control pulses of the semiconductor controller is activated. <IMAGE>
