Title: Processing analog signal in combine harvester - processing steep edge of signal to TTL compatible one, with signal counting
Inventor: BISCHOFF LUTZ
IPC: A01D41/127
Filed: 1990-11-08
Abstract: The analog signals are generated by falling crops onto a sensor, triggering appropriate pulses. The sensor transmits a proportional output signal, corresp. to the crop quantity, via a converter, with a steep rising flank, as well as a wide frequency spectrum with reducing amplitudes. The steep rising flank of the signal is processed into a TTL signal and counter. Pref. the electric signals are first amplified and rectified, then smoothed and the rising flanks transformed into a needle pulse via a differential member. Simultaneously the d.c. voltage portion is removed from the superimposed signals. The needle pulses trigger an electronic switch, whose output carries narrow, rectangular pulses with constant amplitudes, supplied to a counter.

Title: Electrolytic zinc@ and copper@ plating - using aq. ethylene di:amine electrolyte and zinc@ or copper@ spiral anode
Inventor: CLASEN HERMANN DIPL CHEM DR
IPC: C25D3/22
Filed: 1991-06-08
Abstract: A process is disclosed for the electrolytic preparation of strongly-adhering layers of Cu and/or Cu on negatively polarised metal substrates, particularly comprising Fe, Zn, Cu or Sn, by means of a positively polarised electrode of metallic Zn and/or Cu and an aq. soln. contg. ethylene diamine. At the start of the process, the electrolyte only comprises aq. ethylene diamine or contains the electrolytic reaction prods. formed at the outset with aq. ethylene diamine. The process can be carried out without an electrolyte bath, using a flat positive electrode spiral of Zn or Cu. The spiral is covered with a separator which is permeable to the electrolyte, a flexible elastic bag pressing the sprial against the separator. Filling with electrolyte is effected by pressing and releasing the bag by means of a snout piece dipping in the electrolyte. During electrolysis, the electrode is moved in contact with the snout piece rapidly over the surface to be metallised, so that no powdery metal is deposited. ADVANTAGE - The process permits the use of ethylene diamine instead of ammonia with its irritating fumes. Cu and Zn may be deposited together

Title: Controlling reproduction sound level for matching to listening chamber - by regulating loudspeaker signal according to difference between generated and detected auditorium test signal
Inventor: LEE HEUI-SU
IPC: H04S7/00
Filed: 1992-01-30
