Title: Regeneration of waste chromate solns. by pptn. and electrolysis - to recover chromic acid and barium-contg. precipitant
Inventor: MECHLER RAINER DIPL ING
IPC: C23C22/86
Filed: 1991-03-22
Abstract: A process is disclosed for the regeneration of chromate solns., esp. from chromate-contg. effluents and/or process solns. The process firstly comprises chemical precipitation, followed by solid/liq sepn. and electrolysis in a diaphragm cell, wherein the effluent or process soln. is converted to chromic acid. The liquor is treated with barium ions; the pptd. purified barium chromate is removed from the system during the solid/liq sepn.; the precipitating agent and the chromic acid are formed from the barium chromate thus produced, and its sludge; and the recovered precipitating agent is recycled to the pptn. stage. A process is also claimed for the dissolution of insoluble barium chromate from chromate solns., by precipitating it as above, followed by the addn of sulphuric acid to give chromic acid and barium sulphate. USE/ADVANTAGE - The invention can be used in the chromium-plating industry, in the chromate-passivation of metals prior to painting, and in the extraction of Cr from its ores, to reduce pollution and improve materials utilisation. It overcomes some of the disadvantages (complexity, cost) of previous methods of chromium ion recovery.

Title: Bending of e.g. insulated glass panels, to form circular or part circular bend - using distance holder section which is displaced longitudinally and displacement path measured using light barrier
Inventor: BAYER FRANZ XAVER
IPC: E06B3/673
Filed: 1992-08-05
Abstract: Individual feed steps respectively increasing in strength are imposed with bending force, transverse to the longitudinally extending direction of the section which is thereby bent. The distance holder section (2) is displaced by two rollers (3) spaced at a distance on parallel shafts, driven in the same direction. It is supported against the bending force and it is displaced alternately in one or the other extension direction. At least one marking (6) is applied, at the section (2).

The determined measurement values are compared with a specified desired value. With a deviation between this and an actual value the rollers (3) or their drive are controlled. In the case of a too short actual value of the path the rollers are driven longer, and in the case of a too long actual path value they are driven shorter. The feed of the pressure roller (4) is specified and is controlled using a microprocessor or programmable controller or similar. ADVANTAGE - Continuous arc shaped bending is achieved quicker and more simply than hitherto.
