Title: Weighing of principal component e.g. of chocolate on industrial scale - by delivering material, such as cocoa butter, in turn to number of batch weighers and automatically adding wt. signals together
Inventor: KUSTER WERNER
IPC: G01G11/14
Filed: 1990-11-23
Abstract: The material is delivered in turn to at least two separate batch weighing machines, and the wt. signals from all of the weighing machines are added together. The wt. signals from the weighing machines which at a partic. moment do not contain the material are stored, and these stored signals are added to the signal from the weighing machine which does contain the material. Delivery of further material is stopped once the sum of the wt. signals reaches a predetermined value. The weighing machines are emptied in turn as soon as the wt. signal from each one is determined. The individual weighing machines are filled with the material at a greater rate than they are emptied. Delivery of the material into the washing machines is achieved by at least one reversible conveyor belt. The period between the end of filling and determining the weight signal from a weighing machine is fixed. USE/ADVANTAGE - Used partic. in mfr. of chocolate and similar prods. where the principal component e.g. cocoa butter is supplied automatically in weighed quantities to the processing equipment. The material is weighed continuously in a practical manner and with a greater deg. of accuracy.
Patent DE-4040252-A1 (DE)
Inventor: STANDKE BURKHART DR
IPC: C08F4/00
Filed: 1990-12-17
Abstract: Alkaline earth metal alkylates having a spherical particle habit are prepared by dissolving an alkaline earth metal alkylate in a solvent, adding a second solvent which dissolves the alkaline earth metal alkylate only with difficulty or does not dissolve it at all, but which is homogeneously miscible with the solution of the alkaline earth metal alkylate in the first solvent, removing the first solvent and then removing the second solvent. The particle size can be controlled by means of the shear gradient during the precipitation or by the use of emulsion stabilizers. Emulsion stabilization leads to particles in the size range 0.5 to 20  mu m with a particularly narrow particle size distribution. Catalysts for polyolefin synthesis can be prepared on the basis of magnesium alkylates prepared by the process according to the invention. The polymer is advantageous with respect to particle habit and particle size distribution, compared with the prior art. A narrower particle size distribution, and thus a reduction in undesired oversize and undersized particles, and a smoother surface structure are achieved.

Title: Dry cleaning of textiles and leather with solvent esp. tetra:chloroethylene - with removal of solvent by centrifuging followed by blowing with air
Inventor: BAZIN DIETER
IPC: D06F43/08
Filed: 1991-09-23
Abstract: In the dry cleaning of textiles and leather with tetrachloroethylene and similar solvents, after removal of the solvent by centrifuging, remaining solvent is removed from the cleaned articles by blowing with fresh air, controlling the temp. and the air speed w.r.t. the solvent content of the dry air. Pref. the dry air for removal of the solvent from the articles is heated to 40-80 (50-65) deg.C, esp. in a radiator to which the necessary heat is supplied by means of a heat pump from the solvent condensation unit. The air feed is controlled by measuring the amt. of solvent in the air. At the start of the air blowing phase, during the period of high solvent load, a low air speed of 2-20 (5-12) cubic m/min. is maintained, and is raised by to 4x (2-3x) after the amt. of solvent in the dry air has dropped. ADVANTAGE - The tetrachloroethylene concn. in the air in the workplace is low (1 ppm), and the solvent content of the cleaned articles is reduced to 1/5. Solvent recovery is good
