Patent DE-19730047-A1 (DE)
Inventor: ECKSTEIN DIETRICH
IPC: B60N2/06
Filed: 1997-07-14
Abstract: The invention uses a small D.C. motor as a base the winding of which is designed to allow a high idle rate with a simultaneous high starting torque. Thus a motor with a characteristic speed curve (3) having a steep slope is provided. Through speed control or regulation, in particular by electric impulsion modulation, a motor flat characteristic curve (5) or a motor characteristic curve (7) with a particular pattern can be obtained from the speed characteristic curve having a steep slope. Said motor (5, 7) characteristic curves could only be obtained in the past with a proportionally bigger and heavier motor.

Inventor: SCHUERFELD ARMIN
IPC: F02M26/67
Filed: 1998-01-16
Abstract: An EGR (exhaust gas recirculation) valve has at least one valve head connected to a valve stem that works together with a valve seat. It controls the connection of the exhaust channel to the induction pipe of an internal combustion engine. A computer processes operating parameters according to the operating state of the engine.

Title: Harvester rotary mower equipment for crops and raw materials
Inventor: REISIG PETER
IPC: A01D43/00
Filed: 1998-03-09
Abstract: The mower units rotate round vertical axes on a line at right angles to the line of travel so as to fill out the full extent of the roller front face. An overshot conveyor reaching right across the roller rotates around a shaft running horizontally across the line of travel, so conveying elements (13) work upwards in the vertical and against the line of travel only. The turns of a transverse conveying screw (18) terminate near the mower tool opening (20). The two mower units are plate or drum type mowers so the deepest point of the conveying element lies above the bottom setting of the cutter blades (5). The conveying element is formed by two centrally divided parts each with own drive and is designed as a pickup implement with controlled tines, the pickup rotation shaft being joined to a support fitted with radiating conveying elements. The conveying rotation circle is almost the diameter of the screw as mounted one radius above the conveying element so as to lie close together in mirror fashion.

Title: Cleaning metal objects in plasma
Inventor: HOEING THOMAS
IPC: B08B7/00
Filed: 1998-06-12
Abstract: The metal objects to be cleaned (40) are placed in a vacuum chamber (10) in which inert gas, preferably argon, has set up a pressure of less than 10 Pa whereupon plasma partly or totally enrobing the objects is ignited.   Negative potential of minus 500 V is applied to the objects (40) opposite to the ptoential of the plasma so that the inert gas ions accelerated towards the objects necessarily remove the impurities from the surface of the objects.   The argon can be introduced as a splutter gas and the objects have curves of equal radius of a few mm.   In a variant, metal objects are placed as bulk charge in a nonconducting rotating container placed in a vacuum chamber of inert gas using negative potential connections and an object holder so placed as to enrobe the objects partly or totally with the plasma etc.   The container can both oscillate and shake etc.

Title: Ultra-fine air filtration unit for use during domestic vacuum cleaning
Inventor: KLOEBER MARTIN
IPC: B01D47/16
Filed: 1998-06-30
Abstract: The ultra-fine filtration unit can be an integral or additional part of a domestic vacuum cleaner, and uses a water spray under centrifugal action as the collecting medium. Air is mixed with water through sprays (23) onto rotor blades (8), driven by incoming air (6). The rotor blades form the top of a number of concentric cylinders (14,15,16) which abut against a base (19) whose inward rising shaft ends in a core (25). The whole assembly rotates about bearing (21). Teeth in the core engage others in an inner rotor (24) so that the rotor rotates at a much higher speed than the primary rotor. Water fed into the inner rotor through a line (28) strikes a diffuser (100) to form a fine spray. The aerosol mixture is passed through a wall (14) onto a filter cloth (32). After passing through the cloth the air passes through a wall (15) to come into contact with activated charcoal (34) to absorb gaseous pollutants such as solvents or formaldehyde. The filters (32,34) are easily removed once the cover (11) has been lifted. Clean air escapes at a clean air outlet (53) and wash water is removed at a further outlet (4).
