  • Device for magnetic-inductive measurement of the quantity of mixture flowing through a pipeline
    Patent number: 5852362
    Abstract: A device and a method for its manufacture, for magnetic-inductive measurement of the quantity of mixture flowing through a pipeline into which the device has been incorporated. The device includes a housing having a measuring tube with an electrically insulating lining therein. The lining substantially consists of wear-resistant, insulating ceramic material in the form of tiles applied on a layer of plastic material having a thickness between 3 and 10 mm. The joints between the tiles are filled with plastic material. The housing contains magnetic coils. A pair of electrodes are mounted in the measuring tube and extend through the wall of the measuring tube and are insulated in relation to it. Within the housing, the electrodes are connected to lines leading to measuring members for measuring the voltage difference generated in the flowing medium by the magnetic field of the magnetic coils.

  • Method of preparing lacitol monohydrate and dihydrate
    Patent number: 5726303
    Abstract: The invention relates to the new product lactitol monohydrate and to a method for the production of crystalline lactitol. The crystalline lactitol monohydrate can be obtained bij seeding an aqueous lactitol solution of a special concentration under special conditions causing the lactitol monohydrate to crystallize and recovering the product. From the mother liquor a further amount of lactitol dihydrate can be recovered. Crystalline lactitol dihydrate can be obtained using different special conditions. Lactitolmonohydrate can further be obtained by mixing one part bij weight of an aqueous lactitol solution of a suited concentration with 1 tot 3 parts bij weight of methanol or ethanol and cooling the mixture to 15.degree. tot 25.degree. C.

  • Method of manufacturing a deflection unit
    Patent number: 5355578
    Abstract: Method of manufacturing a deflection unit comprising a set of diametrical deflection coils, in which method the coils are placed on a jig which supports each coil at a plurality of locations and in which a coil support of synethic material is urged against the free surface of each coil. The coils are mechanically anchored by means of, for example an ultrasonic welding process in which the locations of the coil support situated opposite supported locations of the coils are softened and pressed into the coils. The coils are not deformed in that case and their mutual position defined by the jig is accurately maintained.
