Abstract: For producing forked roots of turbine blades, the turbine blades are, in a first step, roughed-in and smoothed (finished) on their outer faces in a single operation with two rigidly coupled disk milling cutters that are provided hard metal cutter inserts. In a second step, the forked root is formed with fingers by a set of rigidly coupled disk milling cutters that are provided with hard metal cutter inserts. The disk milling cutters form slots in the forked root. All of the slots are simultaneously opened (roughed-in) and smoothed (finished), the slots having parallel walls.

Abstract: A method for preparing beads containing at least one active ingredient, such as a flavor, fragrance, vitamin, and/or coloring material, to food or tobacco products, where the active ingredient is released at a controlled rate. Discrete droplets of the active ingredient and an acid polysaccharide are formed in an aqueous medium, then the droplets are converted to water insoluble gel beads by introducing the droplets into a solution containing multivalent cations, thereby building a suspension of gel beads. The beads may then be added to the food or tobacco product in an effective amount to flavor, perfume, vitamize, and/or color the product. The beads are heat and mechanically stable.

Abstract: A machining tool (1) has a tool body (2) with tip seats (6, 7, 8, 9), to which cutting tips (11, 12, 13, 14) are assigned fixedly and individually. The cutting tips (11, 12, 13, 14) belong to a set of cutting tips. The machining tool (1) includes further sets of cutting tips, again with cutting tips (11, 12, 13, 14) individually assigned to the tip seats (6, 7, 8, 9). In order to assure that each cutting tip (11, 12, 13, 14) will be mounted on the tip seat (6, 6a, 7, 7a, 8, 8a, 9, 9a) on which it was ground, both the tip seats (6, 7, 8, 9, 6a, 7a, 8a, 9a) and cutting tips (11a through 14a) are provided with markings (34, 35), which allow an unequivocal, unmistakable association.

Abstract: A microbiological process for producing vanillin and other useful products from ferulic acid is disclosed. Vanillin and guaiacol are recovered from the process using a differential pH extraction where the guaiacol is recovered at a pH of greater than 9 and the vanillin is recovered at a pH of from about 5 to about 8.
