Title: Method for thermal oxidation of liquid waste substances
Inventor: LISTNER UWE
IPC: F23G7/00
Filed: 1995-11-03
Abstract: In the method, the liquid waste substance is vaporized and oxidized in a stream of hot flue gas 4.  This stream of flue gas 4 contains the oxygen necessary for oxidation. The essence of the method is that the liquid waste substance is sprayed into the stream of hot flue gas 4 as a fan-shaped flat jet with a component which is perpendicular to the main direction of flow, by means of one or more dual-substance nozzles 6 which are operated in a pulsed mode at a frequency of 5 s-1 to 70 s-1, and preferably 10 s-1 to 20 s-1, a fan-shaped spray carpet 7 with relatively large droplets of large range and a fan-shaped spray carpet 7 with relatively fine droplets of small range being generated in an alternating cycle at each dual-substance nozzle 6, so that the stream of flue gas 4 is supplied alternately with finely sprayed droplets of small range and large droplets which penetrate the flue gas with a relatively large range of throw.  Numerals refer to Fig. 1.

Title: Flotation method for non-ferrous metal variable ores
Inventor: OKAMOTO HIDEYUKI
IPC: B03D1/02
Filed: 1996-02-06
Abstract: The present invention concerns a method of separating variable ores containing copper,  lead, zinc and the like as the refining material for non-ferrous metals and gangue minerals such as pyrite, quartz, feld spar and the like from dug out ores and, particularly, it relates to a  flotation method.     For obtaining non-ferrous metal valuable ores as concentrates from ores by a flotation method, flotation is conducted by using gaseous sulfurous acid or aqueous sulfurous acid as a depressant for controlling the floatability of pyrite.  The flotation method comprises measuring the redox potential of an ore solution before and after the addition of gaseous sulfurous acid or aqueous sulfurous acid and determining an optimum addition amount by utilizing a proportional relationship present between the difference of the potential and the valuable quality enhancing rate.     According to the method, it is possible to judge the effect of depressing pyrite, that is, the effect of sulfurous acid for enhancing the valuable quality without complicate analysis or test and, further, when the method is applied to automatic control, an utmost economical merit can be obtained by quality control of concentrates or saving of wasteful consumption of the reagent.

Title: Ventilation system for arc-resistant switchgear enclosure
Inventor: RENNIE JON S
IPC: H02B1/56
Filed: 1996-10-02
Abstract: An improved arc-resistant switchgear enclosure is disclosed.  In preferred embodiments, an internal arc chamber is formed by assembling modules and creating a void within the center of the switchgear enclosure. As multiple compartments or modules for a switchgear enclosure are connected, an arc chamber is created within the enclosure. Upon initiation of an arc fault within a particular compartment, a relief flap or cover for that particular compartment opens to channel the pressure and the gases into the internal arc chamber or directly through the top of the enclosure. Pressure and gases vented into the internal are chamber flow horizontally through the arc chamber until a path to the top of the switchgear enclosure is reached. These, pressures and hot gases are then channeled upward and safely out of the switchgear enclosure.
