Patent SE-8701744-L (SE)
Inventor: DEMARTHE J-M
IPC: C22B3/00
Filed: 1987-04-28
Abstract: The parent patent described the leaching of a sulphide ore or concentrate, contg. Pb and other metals, with an aq. soln. contg. the chloride(s) of Cu, Bi and/or Ag, using below the stoichiometric amt. of chloride needed for complete soln. of the Pb. - In this addn. the Pb in soln. is recovered as PbCl2 crystals, which are then melted and reduced by H2. Redn. is pref. at 750-850 degrees C., esp. using H2 diluted by an inert gas and injected into the molten PbCl2. The hourly flow of H2 is pref. at least twice the stoichiometric amt. necessary for total redn. of the PbCl2; and the H2 in the gases leaving the redn. process is pref. sepd. from the HCl obtd. and recycled to the redn. process, whereas the HCl is recycled for dissolving the lead. - Metallic lead with high purity can be obtd.; the Cl ions are directly recovered as HCl which is recycled; and the reducing agent is inexpensive. The process also eliminates extra processing stages which were necessary with the earlier patents.

Abstract: Protection arrangement for units for rotation of excavator buckets, by means of an output shaft (8), a hydraulic motor (20) and also, between the motor and the output shaft, a transmission (12, 13). The transmission (12, 13) is a self-braking worm transmission whose worm screw (13) has bearings which permit axial movement of the screw under the effect of forces in the transmission. A spring arrangement (25) holds the screw in a normal position up to a certain level of force effect. A detection member (25) detects the axial position of the screw and is coupled to a control arrangement (23) connected to the motor. In the event of force effect over the said level, the screw moves axially and the detection member couples the motor (20) to the drive source for rotation in the direction of the force effect. As a result of the turning of the output shaft in the direction of the force effect, the unit is protected from breaking due to excessively great, external forces.

Abstract: A process and apparatus is disclosed for the fabrication of press plates hardened by the use of plasma ion nitriding techniques to produce wear resistant decorative laminate containing alumina grit while improving associated press plate useful life. The application of this process to press plates having exacting final microfinish requirements is possible due to the determination of interdependancies between parameter settings and expected results. These interdependancies include the work piece geometry, surface and subsurface structure and desired results, process temperatures, pressures, and duration of heat-up time, thermal loading, reflective radiation and heat effects, cooling systems, and gas mixture composition.
