Title: Redn. process for recovery of metals from slags - by forming sulphide melts of controlled compsn. for sepn. of useful metals
Inventor: MAEKIPIRTTI SIMO ANTERO IIVARI
IPC: C22B7/04
Filed: 1976-10-26
Abstract: A process for redn. of useful metal contg. Fe-contg. slags as well as intermediate products partic. from Cu and Ni melting processes. The slags are reduced opt. with addns. of Fe and/or S, such that the compsn. in the solid state corresponds to the bornite-pyrrhotine equilibrium and to such a quantity of metallic phase that the formation of Ni, Co pentlandite is avoided. The metallised sulphide melt is slowly cooled and the useful metals are sepd. Useful metals are recovered in low proportions of high Fe-contg. salgs and oxidic, sulphidic or metallic intermediate products of pyrometallurgical processes under better control than processes used hitherto. The process requires the control of compsn. of the sulphide melt by addn. of Fe scrap, Fe sulphide or elementary sulphur. By cooling of the melt, the Fe contg. phase crystallises out along with elements such as Ni, Co, Ga, Pt, etc. conc. in it, while the usual Cu sulphide phase can be sepd. by magnetic means or other usual processes.

Title: Diamond cutting and grinding system - has finely adjustable member and sensor controlling cutting angle and depth of cut
IPC: B24B9/16
Filed: 1976-11-13
Abstract: The diamond cutting, grinding and polishing system employs a system of coordinates for positioning the diamond to give a depth of cut according to a formula in which half the diameter of the diamond is divided by the sine of the angle of the facet. The diamond grinding machine used has a guide member (21) with a sensor (27, 28) which registers this depth of cut, and which can be adjusted for fine limits. This is combined with a switch (22) and the length of the sensor can be changed after the operation. A further contact is operated to control a motor or magnet to lift the diamond from the grinding tool. The sensor and the diamond holder (23) are made of a metal which is compensated for thermal expansion. A locating ball is incorporated, operated by a micrometer so that the facet angle and switch member can be finely adjusted.
Patent DE-2659015-A1 (DE)
Title: Regeneration of carbonate solns. used for desulphurisation - by stripping of soln. with high bi:carbonate content
Inventor: SCHLAUER JOHANN DIPL ING
IPC: C10K1/12
Filed: 1976-12-27
Abstract: Regeneration of alkali metal carbonate solns. used to desulphurise hot CO2-contg. gases under pressure is carried out by (a) depressurising the soln. (b) adjusting the alkali metal bicarbonate content to >=55 wt. % based on the total alkali content, (c) stripping the soln. at its b.pt. to remove H2S and some CO2, and (d) recycling the soln. without cooling to the desulphurisation step. Maintaining a high bicarbonate concn. reduces the amt. of CO2 removed by stripping; this increases the selectivity of the regenerated soln. for H2S removal and increases the H2S concn. in the stripper off-gas.

Title: Removing gas cushion formed in electrolytic prodn. of aluminium - using lance with flexible hose attached to exhaust gases of combustion engine
Inventor: ROEKHOLT JOERGEN
IPC: C25C3/06
Filed: 1977-05-10
Abstract: In the prodn. of Al by electrolysis of Al2O3 dissolved in molten cryolite, a gas cushion is formed at the anode of the electrolytic cell. A tubular lance is used to remove the gas cushion. The lance is connected through a flexible hose to a source of pressurised gas which is the exhaust gas of a combustion engine in a movable machine. The mouth of the hose is directed into the cushion to blow away the gas. The drawbacks associated with the conventional methods using compressed air are avoided. The combustion engine used may already be present as the crust breaker. The gas cushion may be removed very quickly by this method thus increasing prodn. saving energy and reducing the emission of polluting gases.

Title: Arene oxidn. to quinone and epoxide derivs. - by exposing arene soln. to high voltage field while passing through oxidising gas
IPC: C25B3/23
Filed: 1977-05-11
Abstract: Arenes, which are opt. alkyl- or aryl-substd. or consist of condensed ring systems, are oxidised to arene quinones and -epoxides by exposing an arene soln. to a high voltage field in a field generator, while passing O2, air or an O2-inert gas mixt. through the soln. The reaction mixt. is then worked up to separate the prods. from soln. Arenes, alkyl-substd. arenes and condensed ring systems are oxidised to quinones, useful as organic intermediates. Aryl-substd. arenes yield epoxides, useful for cancer research. The O-atoms are activated by field effect inside gas-bubbles. Oxidn. takes place without the use of expensive oxidising agents. Energy consumption is below that required in electrochemistry. The process forms no waste prods. The solvents can be recovered completely.

Title: Heat store utilising latent heat - using heat transfer liq. of different density to storage material and having internal agitator
Inventor: LAING GEB MELCHIOR INGEBORG
IPC: F24V30/00
Filed: 1977-06-06
Abstract: Heat store consists of a vessel contg. a storage material which stores latent when changing from the solid to the liquid state. Heat is transferred by means of an immiscible heat transfer liquid which is circulated round and external circuit. The specific gravity of the heat transfer liquid should be different from that of the storage material. An agitator element is mounted in the heat transfer liquid layer to create an intimate mixture between the storage material and the heat transfer liquid. If the specific gravity of the molten storage material is greater than that of the heat transfer material, the rotor is at the top- if vice versa then it is at the bottom. Device is used for storing heat esp. in conjunction with solar energy systems or heat pumps. Gives (a) improved heat transfer between the solidifying storage medium and the heat transfer liquid; (b) avoids mechanical stresses in the vessel due to volume changes; (c) the material solidifies into discreet particles and not into a single mass.

Title: Lamellar ring spring for motor vehicle suspensions - ensures constant bending moment and gradual change in spring constant
Inventor: HOFF HANS DIPL ING
IPC: F16F1/32
Filed: 1977-10-08
Abstract: The lamellar spring suspension is used in motor vehicles for improving the adaptation of the chassis spring suspension to different road surface conditions. The spring constant is varied and the oscillation damping is also varied without use of parallel connected shock absorbers. The lamellar spring ends are held in a groove of the hub and the other free end is held in a groove of a clamping sleeve. A constant bending moment is generated when twisting the hub relative to the sleeve in the lamellar ring springs. The bending moment is increased and the geometrical design of the springs is such that their effective spring length is gradually shortened. The axial contact pressure force of these springs can be adjusted with an adjusting screw and an associated leaf spring.
