Patent DE-3742652-A1 (DE)
Title: Process and apparatus for the production of wood material boards
IPC: B27N3/08
Filed: 1987-12-16
Abstract: The invention relates to a process for the production of wood material boards, in which the wood material particles are coated with a curing agent-free binder, subsequently scattered to form a nonwoven material and are then pressed. Before commencement of the compaction phase, microcapsules which have capsule walls that are inert towards the binder and which contain a curing agent for the binder in the gaseous phase or in the binary phase with a gaseous carrier material are introduced into the nonwoven material. During the compaction phase in the press, the capsule walls of these microcapsules are degraded, and the gaseous curing agent is liberated. In the apparatus for carrying out this process, a device for the production of the microcapsules containing the curing agent in the gaseous phase or in the binary phase with a gaseous carrier material is arranged in the vicinity of the press and connected at a short distance to a mixing station located before the scattering station or to a mixing station located in the scattering station for mixing the microcapsules with the coated wood material particles. The scattering station is arranged in the immediate vicinity of the press inlet.

Abstract: A process for thermal processing of noncompostable domestic waste comprises comminution of the waste, its drying, with the aid of flue gases moving in a parallel current flow and thermal decomposition, with the aid of flue gases moving in a counter current flow which are carried out separately with maintaining a temperature gradient along the flow of flue gases at 5-10 K/m at the stage of drying and at 10-20 K/m at the stage of thermal decomposition. Solid products are removed for magnetic separation, and gases after the thermal decomposition stage are subjected to wet cleaning in at least two stages with isolation of tarry compounds at the second stage, where-after the cleaned gases are subdivided into two streams, using them as fuel, one of the streams being directed to the drying stage and the other, to the thermal decomposition stage. An apparatus for effecting the process is also described.

Abstract: A distribution device (10) for spreading material, especially for chaff and short straw, which is arranged in the discharge region of, for example, a screen box, in order to discharge the spreading material laterally in a uniformly distributed manner, is to be designed in such a way that the spreading range of the spreading material is variable within as wide limits as possible. For this purpose, the distribution device (10) is composed of a collecting conveyor (16) and of a throwing conveyor (20') which are essentially independent of one another and of which only the throwing conveyor (20') serves for distributing the spreading material intercepted by the screen box. The throwing range can be varied according to the arrangement and adjustment of various setting facilities on the throwing conveyor (20'). Distributing devices (10) of this type are found mainly in combine harvesters. <IMAGE>

Title: Pass design for the rolls of rolling stands with three or more rolls
Inventor: SCHLANZKE CLAUS
IPC: B21B1/16
Filed: 1988-11-10
Abstract: To roll solid cross-sections, e.g. bar steel and rods, the rolls 35, 36, 37, 38 of roll stands which have three or more rolls are provided with curved working surfaces 12 which roll grooves 5b into the rolling stock, in particular a round feed cross-section 15. The salient portions 5a between the grooves result in a cloverleaf pattern 5. Since the material is stretched downwards in the region of the salient portions 5a due to the marked decrease in height brought about by the working surfaces 12 of the rolls, there is an increase in length without an increase in width and without a significant increase in height in the region of the salient portions 5a. <IMAGE>

Title: Lung-automatic valve
Inventor: GUMPERT ULRICH
IPC: A62B9/02
Filed: 1988-12-15
Abstract: The invention relates to a lung-automatic valve for protective compressed gas breathing equipment, which comprises an intermediate pressure chamber and a breathing pressure chamber which are separated by a perforated disc provided with concentric bores. The intermediate pressure chamber comprises a membrane receptacle with an elastic membrane which surround a control chamber. The control chamber is connected via a metering bore arranged in the membrane receptacle to the intermediate pressure chamber and communicates with the breathing pressure chamber via an auxiliary valve. When the valve is closed a pressure corresponding to the intermediate pressure is built up in the control chamber, so that the membrane is pressed against the perforated disc and closes the bores. In the breathing-in phase the auxiliary valve opens, and a pressure drop relative to the intermediate pressure chamber occurs in the control chamber, the pressure drop causing the membrane to be lifted off the perforated disc and releasing a corresponding air stream.

Title: Method for direct electrochemical deposition of powdered conductive polymers
Inventor: BECK FRITZ PROF DR
IPC: H01M4/60
Filed: 1989-03-02
Abstract: The preparation of powdered (pulverulent) conductive polymers (polymers from anilin and its derivatives, aromatic compounds [aromatics] and heteroaromatic compounds [heteroaromatics]) as active masses in batteries, as a filler in thermoplastics and elastomers, and as pigments of coatings (paints, varnishes, lacquers) and electro-dipping primers generally takes place on a chemical (oxidative) basis. The oxidants used in the process must, having been reduced, be separated off and then disposed of. They contaminate the polymer, which in practice results in major problems. In accordance with the process according to the invention, direct electrochemical deposition of pulverulent conductive polymers is achieved, with high current yields, on an aluminium anode. The single electrochemical pretreatment of the aluminium electrode comprises the deposition of polymers at the pitting potential of the aluminium, employing aqueous, monomer-containing nitric acid. In the process, polymer nuclei are produced in the pits formed. In a second stage, the polymer can be deposited in powdered form at more negative potentials, while avoiding over-oxidation (Figure 1). After some time, given a potentiostatic procedure, constant current densities are established. The deposited powder can be removed mechanically and the electrode can be reused (Figure 1, batches A-E). The powder produced contains just traces of aluminium (200 ppm) and no iron. <IMAGE>

Abstract: In a speed-measuring system for road vehicles, having a plurality of light barriers (L1, L3, L2) arranged behind one another in the driving direction and an evaluation circuit for the electrical signals produced when the light barriers respond, an additional light barrier (L4) is arranged at a distance (b) above or below the remaining light barriers (L1, L3, L2). The speed calculated from the signals of a measuring light barrier (L1) and the additional light barrier (L4) is compared with a speed calculated by the remainder of the system, and the measurement result is specially marked or rejected if the percentage difference is above a specific tolerance level. As a result, any measurement errors which could be produced by inexpert installation of the light barriers are detected. <IMAGE>
Patent DE-3915731-A1 (DE)
Inventor: HAACKER INGO
IPC: B01D53/34
Filed: 1989-05-13
Abstract: To reduce their nitrogen oxide content, flue gases from burners are catalytically treated with ammonia vapour, which is fed to the flue gases via a carrier air stream. If ammonia water is used instead of pure ammonia, the water fraction must also be evaporated. Solids, which are obtained as solid residues in evaporation can be dissolved in the ammonia water. In order to avoid the separation of a solid residue stream from the process, the ammonia water is partially evaporated, the vapour formed is swirled in a hot carrier air stream and the remaining liquid is distributed in the carrier air stream with a propellant. By this means the solid residues produced in the form of fine- grained aerosols are discharged without problems in the carrier air stream. <IMAGE>
