Patent DE-4312152-A1 (DE)
Title: Conical-cylindrical pouring device for metal cans and other containers
Inventor: SCHMIDT GEB SCHLITTER
IPC: B65D25/48
Filed: 1993-04-14
Abstract: The conical pouring device is preferably used for metal cans in order to remove small quantities of varnishes/paints/chemicals from the container without drips and runs. It has been shown in practice that it is very difficult to pour varnishes and paints from the container due to the reinforcing ring fitted onto the cans owing to the high viscosity. In this case, not only is the loss of material unfortunate, but these chemicals constitute heavy pollution to the environment. The user usually wipes these runs up using paper or a rag and throws the soiled material away in the rubbish bin and it is then taken to the land-fill site.

Title: Warm-water inflow control method for microprocessor-controlled domestic dishwashers and washing machines
Inventor: STAMMINGER RAINER DIPL PHYS DR
IPC: D06F33/02
Filed: 1993-10-28
Abstract: In a known water-supply arrangement for domestic appliances, cold, warm or hot water is fed to a washing machine from three separate delivery conduits controlled via solenoid valves. The solenoid valves are actuated in a programme-dependent manner; specifically independently of the water temperatures actually prevailing in the supply systems. Standing water cooled in the delivery conduits has little heat content and is likewise also introduced. In the method according to the invention, cooled mains feed water is rejected altogether and is used only when the temperatures are sufficiently high for a washing or rinsing process. By means of the electrical house BUS installation technique, consumers are informed of the heat content and temperature of the supply arrangement itself and of the appliance water feed conduit. Microprocessors within the appliance decide whether the use of external warm water affords energy advantages in relation to internal heating. The method according to the invention can be employed in electronically controlled domestic washing machines and dishwashers which, moreover, are designed for warm-water and/or cold-water connection.
Patent DE-4337625-A1 (DE)
Title: Process and plant for the biological purification of waste water
Inventor: PAETZ REINHARD DR RER NAT
IPC: C02F3/30
Filed: 1993-11-04
Abstract: In known plants, uncontrolled introduction of the medium with respect to the pollutant content proceeds and there is no influence given on the residence time in the individual vessels. Also, nitrogen compounds are fed at high concentrations and there is an enrichment with nitrifiers. The invention is intended to avoid these disadvantages. In a denitrification reactor (1), activated sludge and wastewater (effluent) are mixed, an anaerobic denitrification proceeding. Some of this medium is injected via two-component nozzles (9), together with air, into the annular space (15) of an aerobic reactor (10), the air being drawn from the air space (17) of the aerobic reactor (10). Wastewater is added to the denitrification reactor (1) via the overflow of some of the medium treated in the aerobic reactor (10). Some of the aerobic reactor (10) medium from the lower part of the same is likewise injected together with air via two-component nozzles (14) into the annular space (15) of the aerobic reactor (10). The two-component nozzles (9, 14) are tangentially arranged, directed upwards, and the residence time of the medium can be influenced in each reactor (1, 10). The process and the plant can be employed and used anywhere where wastewater must be biologically purified, such as, for example, in animal sheds. <IMAGE>

Title: Information system EM field superimposition method
Inventor: WOLF BIRGIT DIPL ING
IPC: H04K1/02
Filed: 1994-04-15
Abstract: Electromagnetic fields of information systems contain information well and can be received and analysed over great distances. To reduce the security risks inherent in such information transmission, the present so-called OverFLOW method can be used. This is a method of superimposing the electromagnetic fields of information systems. A transmitter constantly generates a wide band electromagnetic field. This is superimposed on the received electromagnetic spectrum of the information systems, obtained by a measuring technique. This prevents the radiation which contains information from being resolved and reproduced.
