Title: Biological filter for washing exhaust air from cattle sheds - where water flows downwards through media in tower in which air is drawn upwards by a fan
Inventor: SCHOENHAMMER JOHANN
IPC: B01J19/32
Filed: 1991-04-20
Abstract: Filter consists of water spray nozzles and layers of packings.  There is at least one connection for exhaust air. Water flows downwards and is distributed through the packings and collects in a basin at the bottom of the filter. Air is drawn upwards through the filter by a fan which creates a pressure difference.  As air rises through the filter, the low pressure drop across the packing increases. USE/ADVANTAGE - Because the pressure drop varies, thefilter does not get blocked, as do prior art filters.
Patent DE-4114514-A1 (DE)
Inventor: LOROESCH JUERGEN
IPC: C22B11/08
Filed: 1991-05-03
Abstract: In the so-called cyanidation-in-mill technique, the ores, ore concentrates and gangue material, which are to be leached, from previous incomplete leachings are treated with a cyanide-containing leaching solution already in the mill, gold and silver being leached out at least partially. As compared with the previously known cyanidation-in-mill technique in the presence of hydrogen peroxide, the gold yield can be substantially increased if the leaching is carried out in the presence of a peroxoborate compound. The peroxoborate can be present in a solid and/or dissolved form. Preferably 10 to 60 equivalents of peroxoborate are used per tonne of the material to be leached.

Title: Detecting positions of light reflecting objects, e.g. for testing vehicle shock absorbers - measuring intensity of light reflected from object, e.g., bar=code, and detecting steps in intensity distribution
Inventor: ESCHKE UWE DIPL ING
IPC: G01S17/04
Filed: 1991-10-16
Abstract: A method of detecting the positions of light reflecting objects involves detecting (8) light from a light source at least partially reflected by the object. Light from the source (2) is deflected towards the object (1) by a rotary mirror (4) and fanned out over a defined measurement path (6) so that a light spot is linearly scanned over the surface (11) at a defined frequency. The light is focussed by a transmission lens before or after the mirror and by a receiver lens. The light intensity is detected over the entire measurement path and any steps in intensity interpreted as a transition in the surface structure or one end of the object. ADVANTAGE - Enables position of light reflecting object to be detected at low equipment cost and with compact arrangement.
