Title: Angular position encoder component setting method for vehicle instrument, e.g. tachometer
Inventor: KOBAYASHI YUICHI
IPC: G01D5/249
Filed: 1997-05-30
Abstract: The method involves using a coding disc (34) having a number of arc-shaped slots at differing radii from its centre. The disc operates in conjunction with optocouplers in a housing (35) to define angular displacements of an axis (31) via a 5-bit digital code.  The method involves installing a toothed wheel (40) in an encoder (30) which has the axis as a mounting jig for accurately setting the position of the wheel. The stem is rotated and its angular position information is received by an indicating pointer. When the axis reaches a zero reference angle position value the axis is stopped and the wheel is fastened upon the axis.

Patent DE-19733681-A1 (DE)
Inventor: WATZENBERGER OTTO DR
IPC: C01B21/14
Filed: 1997-08-04
Abstract: The invention relates to a method for producing an aqueous solution of free hydroxylamine by treating a hydroxylammonium salt with ammonia in the counter-current in a stripping column. As a result, hydroxylamine is released and at the same time, the solution obtained is separated into an aqueous hydroxylamine solution and a salt fraction by distillation. The inventive method is simple and mild, and can be carried out on a large scale. The risk of decomposition is minimal due to the low thermal burden, the low concentration of hydroxylamine and the short residence time involved in the process.
