Patent DE-4330805-A1 (DE)
Title: Alternating current source for arc welding processes
Inventor: PUSCHNER PETER DR ING
IPC: B23K9/06
Filed: 1993-09-10
Abstract: An alternating current source for operating welding arcs with the arc being struck again after the polarity change without any additional pulse or RF striking aids is characterised in that the arc is driven from an electrical power source, which has inductance, via a full bridge rectifier composed of controllable valve pairs having freewheeling diodes which can be switched on and off differentially, in that all the valves in the bridge can initially be switched on by means of an intelligent controller at the start of the polarity change so that the source current is short-circuited and the energy which is stored in the welding circuit, with its circuit inductance, can be dissipated via the arc and the short-circuited valves as well as the freewheeling diodes over a period of time, in that a detector is used to confirm the time at which the welding circuit energy has dissipated, and in that only the appropriate pair of valves required for the polarity phase that is about to start can still be switched on as a function thereof, so that the energy which is stored in the source inductance leads to a voltage spike which initiates the restriking.
Patent DE-4335410-A1 (DE)
Title: Process and device for the mechanical separation of liquid from solids
Inventor: BRANDAUER EDGAR DR ING
IPC: F26B7/00
Filed: 1993-10-18
Abstract: The invention relates to a process and a device for the mechanical separation of adhering liquid and internal liquid with the aim of achieving a higher moisture removal than in the case of conventional installations with purely mechanical liquid separation. For this purpose, the solid from which moisture is to be removed is additionally exposed to a microwave radiation during the process of mechanical liquid separation. This has the effect that the solid releases liquid stored in its interior to a greater extent than in the case of a purely mechanical liquid separation, this liquid then being removed from the solid by means of the mechanical separation device. The elevated release of liquid is explained by the partial evaporation of the liquid in the interior of the solid and the pressure elevation associated therewith, which effects an additional overcoming of the adhesive forces between solid and liquid. As far as the device is concerned, a device for the mechanical separation of liquid, for example a filter or a centrifuge, is to be equipped with at least one microwave radiator in a suitable way.
Patent DE-4338228-A1 (DE)
Title: Cyclic process for reprocessing metal-containing residues
Inventor: THIELE WOLFGANG DR
IPC: C22B3/08
Filed: 1993-11-09
Abstract: The disposal of metal-containing residues has hitherto been predominantly by deposition in a landfill, incineration or thermometallurgical processes with considerable pollution of the environment and only low recovery of the metallic materials. The new process should enable, in a cyclic process, metals such as copper, silver, gold and platinum, which are present in combination with other components, including toxic components, to be recovered and at the same time concentrates or residual residues which are non-problematical to process further or to dispose of to be obtained.   For this purpose, the residue material is first treated with sulphuric acid to remove base metals. Subsequently, copper, silver and mercury are dissolved using peroxodisulphuric acid/peroxodisulphate solution and deposited electrolytically with simultaneous regeneration of the solution used. In the presence of noble metals, these are subsequently dissolved using chloride-containing peroxodisulphuric acid/peroxodisulphate solution, deposited electrolytically and the remaining solution is again used in the cyclic process. The remaining residue material can, after being treated again with peroxodisulphuric acid/peroxodisulphate solution and washing, be reused or deposited in a landfill.

Patent DE-4410169-A1 (DE)
Title: Optional water separation in the area of sanitary installations
Inventor: ROTH HARRY DR
IPC: E03B1/04
Filed: 1994-03-24
Abstract: The patent claim relates to the fact that water, after having being used for a first time (e.g. for showers, baths), is separated into an intermediate tank, if appropriate filtered and re-used before the customary discharge into the sewerage system. This takes place via a switch (e.g. rotary switch, toggle switch, twist switch) which is integrated into the sanitary fitting or is separate and with the aid of which the discharge duct is determined. A distributor, with deflection plate or flap, switched in this manner channels the water, via a path A, into an intermediate store. Switching takes place mechanically (shaft, linkage) or electrically. From the store, the water is channelled further, via a pump and a separate pipeline, for secondary use (e.g. toilet flushing). The distributing piece is to be mounted downstream of the Siphon; if appropriate, filter elements and non-return valves are to be installed upstream and downstream of the intermediate store. Path B leads directly into the sewerage system. The water separation can also take place by a fixed arrangement of the discharge pipes and closure of one discharge. The intermediate store, in a vast range of sizes, may be mounted inside or outside the building, above the ground or under the ground.
