Patent DE-19623410-A1 (DE)
Title: Agglomeration of poorly soluble and hydrolysis sensitive materials
Inventor: SEYFFERT INA
IPC: B01J2/16
Filed: 1996-06-12
Abstract: Process of agglomeration of poorly soluble and hydrolysis sensitive materials in which the material, in powder form, is allowed to fall, together with a water-soluble powdered binding material, into a steam atmosphere at 85-105 deg  C. where it spends 0.5-10 seconds. Further free-fall takes place during which drying occurs and contact between primary particles is caused by liquid bridges in the condensate (in which the binding material is dissolved) and only a small amount due to solid bridges. Final drying involves an integrated flow-bed system and the product has a water content of less than 5 (preferably less than 1) wt.%.

Title: Safety belt system for occupants of vehicle
Inventor: WITT MICHAEL T DIPL ING
IPC: B60R22/20
Filed: 1996-07-20
Abstract: The belt system has a tensioner (16), force limiter (10) and belt run optimising device (1) at shoulder height.

Title: Run-down revs determination during three=phase motor stopping
Inventor: JENSEN NIELS DUE
IPC: H02P1/30
Filed: 1996-12-05
Abstract: A method of measuring the run-down and/or direction of a three-phase asynchronous motor (2) controlled by a frequency transformer (1) during its stopping period requires bombardment of at least one coil (A,B,C) briefly with an exciting current. After this at least two phases (u,v,w) are short-circuited and the motor switched off. The turn-count or direction during the slowing-down period can then be determined by measurement of the voltage through a resistor (R), connected to the coil, of the current induced in the non-excited coil. The process requires only a simple-to-build measuring system which may be based on miniaturised semiconductors.
