Title: Device for automatic self-levelling of the body of a threshing-harvesting machine
IPC: A01D75/28
Filed: 1971-06-18
Abstract: Automatic self-levelling of the body of a threshing-harvesting machine is effected by a device which is sensitive to the operation of respective magnetic float switches located in respective interconnected liquid-containing vessels positioned on opposite lateral sides of the body. Each vessel contains two laterally spaced apart float switches connected to electro-valves in an hydraulic circuit for self-levelling actuators so that when either of the laterally outer float switches is operated the actuators are supplied with part of the hydraulic fluid output from a pump to effect correction and when either of the inner switches is operated at a greater angle of inclination, the actuators are supplied with the full pump output to effect rapid levelling. An alarm is operated automatically in the event of excessive inclination of the body of the machine.

Patent ES-446597-A1 (ES)
Title: Metallurgical process using oxygen
IPC: C22B7/04
Filed: 1976-04-01
Abstract: A continuous autogenous multi-stage process for converting non-ferrous metal sulfides, in an oscillating, elongated, gently sloped, sealed, tiltable, rounded cross-section furnace, discharging crude metal or low-iron matte at one end, and silicate slag and sulfur dioxide-rich gas at the other end. The concentrates, fluxes, commercial oxygen, sulfur dioxide, a carbonaceous reducing agent and optionally other materials are introduced into the furnace in stages to provide a molten bath of slag and matte flowing countercurrently. Slag scavenging is accomplished by deconverting to produce low grade, cleansing matte in situ in the slag layer, followed by settling. At least a substantial proportion of the commercial oxygen is continuously blown in through injectors extending through the refractory lining of the vessel and communicating with its interior below the bath surface, where necessary with a protective fluid, desirably surrounding the oxygen. Oscillation of the converter causes the injected gases to sweep back and forth through the bath, and distributes the solids over its surface to provide bath turbulence and interphase contact. Off-gases are desirably recycled. Flexible control means and special apparatus are disclosed.
