Patent DE-4200890-A1 (DE)
Title: Decontamination of soil contaminated with organic material - uses organic material to supply heat required for process
Inventor: REIMANN GOETZ
IPC: F23G5/04
Filed: 1992-01-16
Abstract: A mineral material, which contains organic material, esp. contaminated soil, is subjected to heat treatment in order to remove the organic material. The soil is first subjected to a heating process in which the heat is provided by the subsequent combustion of the organic material. The soil is then dried and subjected to a dry distillation process in which the organic fractions are precipitated. The soil is next subjected to a chemical-physical process and the residual product is then subjected to a carbonisation treatment or is burnt by using the organic fraction to supply the heat. ADVANTAGE - The process decontaminates the soil without polluting the environment.

Title: Weaving head for automatic welding machine - has electromagnetic coils for universal weaving movement of torch nozzle
Inventor: SCHUELER DIERK-HENNING
IPC: B23K9/12
Filed: 1992-08-27
Abstract: A weaving head for an automatic welding machine, esp. for gas-shielded welding, is fixed in a torch holder and consists of a tubular sheath with shielding gas feed lines and a torch segment mounted axially in the sheath. The novelty is that the torch segment (1) is mounted for universal pivotal motion and is in operative connection with electromagnetic coils (8) such that, during various coil drive sequences, different geometric figures are described by the torch nozzle(2). The torch segment (1) has a spherical shape above its nozzle (2) and is mounted in a conventional cardan bearing (4) within the rigid sheath (7). Several electromagnetic coils (8) are fixed within the sheath (7), above the bearing (4) and around the torch throat (3), and are driven such that the resulting directional magnetic forces cause pivotal motion of the torch throat (3), made of ferritic material, and thus opposite weaving motion of the nozzle (2).

The weaving head can be retrofitted to existing welding machines without problems, avoids the use of expensive mechanical drives which are subject to wear, and has minimal dimensions and susceptibility to faults.
Patent DE-4229454-A1 (DE)
Title: Dewatering and juice-removal press - is driven functionally only by two no-load motors with sieve-shaped tray set in vibration
Inventor: KASTEN HEINZ
IPC: C02F11/121
Filed: 1992-09-03
Abstract: The material (7) to be dewatered is placed in the vibrating tray (1) with sieve holes. The motors (5) are fixed to the tray and take over the functions of dewatering and transport of the material (7). Selectively, by pivoting the motors the dewatering intensity and the throughflow speed can be altered. By pivoting the motors with a horizontal position of the motor axis a vertical vibration is produced, i.e. the vibration only works on the dewatering. If the motor shaft is positioned vertically the vibrations run horizontally. Horizontal vibration influences only the transport speed. USE/ADVANTAGE - A clear slurry press, has a low prodn. price and a high dry substance content in the end product.

Title: Device for disposing of installed parts, which are contaminated with, and emit, chemical substances, in the interior of passenger vehicles. - A car for allergics -
Inventor: GERISCH ROLF
IPC: B01D46/54
Filed: 1993-02-17
Abstract: The invention relates to a device which can be used to prevent, in an effective and long-lasting way, the pollution of the air with chemical substances in the interior of passenger vehicles by emissions from parts installed in the interior. Emitting parts are regarded as being seats and backrests which have a substrate of Styropor and foamed material and are covered with leather or textiles, as well as bonded coverings of side parts, dashboards having a substrate of Styropor and/or a foamed material and covered with PVC film, and inside roof linings and the like. The chemical substances emitted from these and other parts and from the adhesives used for fixation purposes may considerably impair the physical well-being of the vehicle user. These pollutants are not only inhaled but moreover they are deposited on the clothing. Sensitised allergics therefore frequently avoid buying a new car and instead tend to buy second-hand cars because they expect that the emission of pollutants may have diminished after 2-3 years of use. The invention starts from the assumption that the passenger vehicle to be disposed of is series-fitted with a fresh air filter or that such a filter is subsequently installed. This object is achieved by the invention of a device via which previously filtered, dehumidified air heated at 100-120 DEG C is ... Original abstract incomplete.

Title: Device for improving the life of filament lamps (incandescent lamps)
Inventor: TIHANYI JENOE DR
IPC: H05B39/08
Filed: 1993-04-08
Abstract: A filament lamp is loaded particularly strongly if it is switched on at the time of the voltage maximum. In order to avoid this surge load, it is ensured by means of a zero-point switch series-connected to the lamp that the switching-on process takes place only in the vicinity of the voltage zero crossing. This leads to an improvement in the life of the lamp and a considerable reduction in the electromagnetic interference.

Filed: 1993-09-01
Abstract: Frame-integrated, hydraulic multiple theft protection, preferably for two-wheeled vehicles, which is fitted into the frame in a manner such that by turning the key of a cylinder lock a small eccentric acts upon a mini pressure generator, filled with hydraulic oil, such that the hydraulic oil passes via a plurality of microcapillaries, likewise running within the frame, into respective mini bellows and, as a result, a ram connected to the mini bellows enters into holes made transversely in the steering shaft and pedal-crank shaft and in this manner block said holes and also the holder for the air pump.

Title: Apparatus for the phase separation of a gas/liquid stream, if appropriate with previous mixing
Inventor: MUSCHELKNAUTZ SEBASTIAN DR
IPC: B01D45/06
Filed: 1993-09-17
Abstract: The invention relates to a gas/liquid separator and a contact apparatus for mixing a gas stream with a liquid and for subsequent phase separation of the resulting gas/liquid stream. According to the invention, a baffle shield (5) is fixed virtually horizontally in the separator above the centrally and vertically arranged feedline (1), the baffle shield (5) having at the outer end a deflection collar (6) which runs roughly parallel to the feedline (1) and on the inside of which facing the feedline (1) are mounted internals (7, 8) generating liquid strands, and the deflection collar (6) and the shell housing (4) delimiting an outflow duct (9) for the gas phase. In the separator, the gas/liquid flow is run against the baffle shield (5) having the deflection collar (6), the flow being deflected downwards through about 180 DEG C. In the course of this there results on the baffle shield (5) or on the deflection collar (6) a liquid film which is broken up by the internals (8) into liquid strands. In the intermediate spaces between the liquid strands, the gas can escape upwards unhindered via the outflow duct (9), which achieves a virtually 100% phase separation. The liquid strands running off from the internals (8) build up in the lower part of the apparatus and can be taken off via a line (3). The principle of phase separation of the separator is also exploited in the contact apparatus according to the invention, which in contrast ... Original abstract incomplete. <IMAGE>
