  • Patent number: 6820941
    Abstract: A clamping device for restraining filament tufts in a bristle cluster includes fixed and movable clamping plates. The clamping plates have apertures that are aligned in the unloaded position and that are offset relative to each other in the loaded position. The movable clamping plates can be displaced relative to the fixed clamping plates, and each movable clamping plate secures a specific portion of the bristle cluster.

  • Publication number: 20040220405
    Abstract: Highly pure triethylenediamine is obtained by a process in which triethylenediamine is freed from high boilers and then the triethylenediamine is vaporized from the mixture thus obtained and is passed into a liquid solvent. The process makes it possible in particular to obtain highly pure solutions of triethylenediamine. Crystallization is generally unnecessary.

  • Patent number: 6677130
    Abstract: Compositions and methods are provided for the treatment of diseases associated with mitogen activated protein kinase cascades. In particular, the mitogen-activated protein kinase p38-2, and polypeptide variants thereof that stimulate phosphorylation and activation of substrates such as ATF2, are provided. The polypeptides may be used, for example, to identify antibodies and other agents that inhibit or activate signal transduction via the p38-2 kinase cascade. Such polypeptides and agents may also be used for the treatment of diseases associated with mitogen-activated protein kinase cascades.

  • Publication number: 20030211070
    Abstract: The wax product for treating or setting up a hairstyle or hairdo includes a composition containing at least one wax or wax-like substance, at least one non-volatile liquid hydrophobic oil and at least one volatile or easily volatilized hydrophobic substance that is a liquid or gas at room temperature. Because of the presence of the volatile substance in the composition a soft wax easily worked in the hair is obtained when the composition is applied to the hair. This soft wax hardens on the hair when the volatile ingredients evaporate. When the composition includes a propellant gas a wax with a larger surface area (wax snow) is produced, which is likewise easily worked into the hair and very effectively fixes or sets the hair.

  • Publication number: 20030071512
    Abstract: A device for manufacturing brush products, in particular toothbrushes, with a bristle magazine having a feed chute for receiving filaments of precut length arranged in a dense array transverse to the longitudinal axis of the bristle magazine. The feed chute has a discharge opening which is bounded by a bristle picker closing the discharge opening from outside, and serves to feed filaments to a recess provided on the bristle picker. The recess receives only a predetermined quantity of filaments, combining them into tufts which are then transferred to further stations for further processing. According to the invention, the feed chute has a magazine bottom on which the discharge opening is formed. The magazine bottom is further shaped in an arcuate configuration tapering essentially in the direction of the discharge opening. This produces a steady filament flow in which dead zones are not allowed to develop.

  • Publication number: 20030041402
    Abstract: A method is provided for manufacturing a function element carrier with function elements, for example, individual tufts made up of bristles and/or massage elements, interproximal cleaning elements, or other elements designed to be fastened to a toothbrush and also perform special functions. The function elements are equipped at their ends intended for anchoring in a toothbrush with an anchor, retainer or axle element. The method includes: (a) inserting several function elements in corresponding recesses of an injection mold, said injection mold being connected via grid or bar shaped channels formed in a die to recesses in the areas of the anchoring ends of the function elements; (b) filling the grid or bar shaped channels with liquefied plastic material and injecting said material at the anchoring ends of the function elements or embedding them therein; and (c) allowing the plastic material to cool and removing a function element carrier made up of a grid or bar shaped plastic frame and the function elements.
