Abstract: 1,198,956. Making microcapsules. NATIONAL CASH REGISTER CO. 7 Jan., 1969 [29 Jan., 1968], No. 947/69. Heading B8C. [Also in Division C3] Microcapsules are produced by dispersing in an aqueous solution of poly vinyl alcohol a solution in a water-immiscible liquid of an alkylene glycol cyclic borate ester and keeping the dispersion agitated for a time sufficient to allow the formation of a complex between the polymer and the ester at the liquid-liquid interface which encapsulates the dispersed droplets. The coatings may subsequently be hardened, e.g. by treatment with a transition metal salt, e.g. vanadyl sulphate. Preferred esters are those of the general formula in which each R is a hydrogen atom or a C 1-7  alkyl group, at least one R being alkyl. A phase separation inducing agent, e.g. sodium, magnesium or ammonium sulphate or gum arabic, may be included in the aqueous phase to assist capsule formation. Numerous core materials (i.e. the water-immiscible liquid in which the borate ester is dissolved) are mentioned, including animal, vegetable, mineral and synthetic oils.

Title: Process for the emission-free drying of a substance in a drying drum
Inventor: KUNZ WERNER
IPC: B09B5/00
Filed: 1994-03-03
Abstract: The process for low-emission drying of a substance in a drum-type drying installation is suitable in particular for sewage sludge, fish meal and sludges from starch factories, soap factories and paper mills, which substances are preferably to be converted into granules. The process is likewise very suitable for drying biomass products such as wood chips, grass, sugar beet chips and the like, since the emissions are very greatly reduced by means of this process. The drying process is carried out in such a way that no unpleasant odors and dusts are emitted to the outside, because the actual drying circulation is closed. Fossil fuels are used as the heat source for the burner for heating this air stream.

Abstract: PROBLEM TO BE SOLVED: To measure the viscosity of a fluid inspected of non-Newtonian fluid, in particular having a high viscosity, in the condition that it remains in a liquid chamber, etc., unchangedly. SOLUTION: A sensing spindle 10 is rotated at a very low speed in such a condition as set on a liquid chamber 25, and a fluid to be tested 26 is allowed to flow up in the gap relative to the inner wall surface of a bushing 17a of an outer cylinder 7 by a groove 24, and the gap between the outside circumferential surface of the spindle 10 and the inner wall surface of the bushing 17a is all wetted so that a uniform film thickness is obtained. In association with slide flow of the fluid 26 inside the gap, the reaction force due to the viscosity resistance acts on the spindle 10 in the reverse direction to its rotation. With this reaction force, the whole rotational drive part 1 and the base cylinder 8 rotate in the reverse direction to the rotational drive direction.  Also an arm member 20 installed on the base cylinder 8 rotates, and an arm 21 abuts to a sensor arm 13a of a load cell 13. Because the abutting force at this time is proportioning to the reaction force due to the viscosity resistance of the fluid tested, the viscosity of the fluid 26 can be determined from the output value of the load cell 13.
