    Abstract: The recovery of rhodium, present as a homogeneous dissolved complex compound especially in residues of products of the oxo process, is carried out in a two-stage process. In the first stage, the residues are treated with a gas-containing oxygen in the presence of a C.sub.2 - to C.sub.4 - monocarboxylic acid and an alkali metal salt of a C.sub.2 - to C.sub.4 -monocarboxylic acid, and are then extracted with water. In the second reaction stage, they are treated again with a gas-containing oxygen, an aldehyde, a C.sub.2 - to C.sub.4 -monocarboxylic acid, and an alkali metal salt of a C.sub.2 to C.sub.4 monocarboxylic acid, and are extracted once more with water.

    Abstract: A walking beam furnace comprises a hearth formed by fixed and walking beams disposed with their axes in the feed direction. Both the walking beams and the fixed beams are divided at positions spaced apart in the feed direction into sections, and each section of each beam is staggered relative to the adjacent section. As a result, the material to be annealed comes into contact with the cooled fixed beams at different positions at each of the conveying pauses and temperature balancing takes place at the points of contact.

    Abstract: The invention relates to a walking beam furnace, the hearth of which consists, at least partially, of longitudinal beams arranged side by side and alternately formed as fixed beams and walking beams. Each walking beam is lifted and lowered with the aid of lifting rollers, which run on ramps. The ramps are prolonged downwards by a longer distance than is required for the working lift of the walking beams. The walking beams are depressed, step by step, into a repair and maintenance plane which lies appreciably below the plane of the hearth, by moving down the lifting rollers into the region of the lower prolongation of the ramps. For this purpose, a lifting rod which connects all the lifting rollers belonging to a walking beam, is connected to an associated actuating cylinder via a pivotally movable perforated arm mounted at a fixed point, the lifting rod being extended piece by piece by means of extension sections and with the aid of a holding device, and being in each case reinserted into a lower hole in the perforated arm.
