Patent DE-2553416-A1 (DE)
Title: Sepn. of dissolved substances from solns. - by raising the soln. temp. before concentration and cooling
Inventor: MARQUARDT KURT
IPC: C23G1/36
Filed: 1975-11-27
Abstract: Dissolved substances are sepd. by concentrating the soln. using membrane sepn. techniques (e.g. reverse osmosis, electrodialysis and/or ultrafiltration) in which the soln. is subjected to a temp. change of T1-To (To being its initial temp.) before effecting concentration. The concentrated soln. is then cooled to T2(T2T1) at which temp. the solutes separate, the temp. differences between To, T1 and T2 being so chosen wrt to solubility that the reqd. rate of sepn. of solute is attained. The process is useful in sepg. K hydrogen tartrate from wine, Cu from etching solns., FeSO4 and FeCl2 from metal pickling solns. and CuSO4 and NH4 salts from NH4 persulphate solns. (used as etching solns.) and for any other substances, whose solubility is strongly temp.-dependant. Blockage of the membrane is much reduced and the membrane area can be reduced. By judicious choice of T2, better crystals separate.

Title: Light blocking system for TV camera - has liq. crystal layer between two polarisers
Inventor: MOTTA PIERANGELO
IPC: G02F1/13
Filed: 1977-03-11
Abstract: The light blocking system is used to determine the amount of light falling on an optical transducer (5) incorporated in the optical system of a television camera or an image converter. It employs a fluidic crystal layer (1), which rotates the polarisation plane of a polarised light beam passing through it through 90 degrees. The fluidic crystal layer (1) is positioned between two polarisation filters (2, 3) with the inner polarisation filter (3) preventing light falling on the optical transducer (5), when no voltage is applied across the fluidic crystal layer (1). Both the two polarisation filters (2, 3) have the same orientation and the blocking system (1, 2, 3) maintains the light falling on the optical transducer (5) at the same level independent of the ambient lighting conditions.

IPC: C25D17/10
Filed: 1977-08-17
Abstract: An anode configuration comprises convolutely wound lengths of anode material rod or wire which form planar coils housed in a perforate anode basket. The opening of the basket is dimensioned such that the coils stack freely in a predetermined pattern within the basket when the coils are fed through the opening. The anode is used for electroplating of Cu, Zn, Cd or Ni onto workpieces. Electroplating efficiency and speeds are increased while there is a minimum generation of sludge or sediment. A maximum surface are of anode material is exposed continuously to the electrolyte as the material migrates from the top of the basket to the bottom during the electroplating operation. The rectangular configuration if the basket opening and dimensions of the coils ensures a vertical side-by-side stacking of anodes within the baskets.

Title: Freeze grinding of cohesive granulate in controlled stages - with recycling of coarser fraction to feed hopper
Inventor: ELGETI KLAUS PROF
IPC: B02C19/18
Filed: 1977-09-29
Abstract: Solids of high cohesiveness are continuously ground by cooling by indirect contact with liquid coolant, then blowing the cooled granulate with a cold gas stream through a grinder, then separating the gas from the solid, the gas, after renewed indirectly cooling, is again used in the blowing process, while the separated solids are graded and the sufficiently fine fraction removed, the remainder being recycled in the process together with new granulate. By breaking the process down into several correctly combined stages, improved grinding is achieved with reduced energy consumption.
