  • Patent number: 9841113
    Abstract: A pressure relief valve for a hydraulic system for controlling a belt-driven conical-pulley transmission. The valve includes an orifice having an opening to admit a stream of a hydraulic medium, and a valve cone to block the opening in the orifice. A spring is carried by the valve cone to apply a restoring force to press the valve cone against the orifice in sealing contact with the opening. A hydraulic plate having a valve bore is provided to receive and guide the valve cone and the spring. A lateral force support is carried by the valve cone to align the axis of the valve cone relative to the axis of the orifice opening.

  • Patent number: 9717324
    Abstract: A method for producing a toothbrush comprises providing a head, a neck portion, and a handle; providing a coupling element; and combining the neck portion to the handle by the coupling element so that an irreversible connection is formed. The individual parts of the toothbrush to be formed can be produced in parallel or successively, wherein some of the parts can be produced by injection molding. A toothbrush formed by the method comprises a head, a neck portion, and a handle; these elements can be produced as building blocks separately and may be connected to one another via a coupling element to form an inseparable connection.

  • Patent number: 9486066
    Abstract: A toothbrush comprises a head, a neck portion and a handle, wherein the neck portion and the handle portion are connected to one another via a coupling element. The connection is constructed as an inseparable connection, i.e., after being combined once, the neck portion and the handle cannot be separated without the brush being destroyed by such separation. A method for producing such a toothbrush may comprise the following steps: providing a head, a neck portion, a handle, and a coupling element, and combining the neck portion to the handle by the coupling element so that an irreversible connection is formed.

  • Publication number: 20150257520
    Abstract: A head for an oral care implement has a mounting surface and at least one tuft mounted thereon. The tuft has a longitudinal axis and a cross-sectional area extending in a plane perpendicular to the longitudinal axis. The tuft comprises a plurality of substantially cylindrical filaments. Each filament has a longitudinal axis and a cross-sectional area extending in a plane that is perpendicular to the longitudinal axis. The cross-sectional area of an individual filament has a substantially non-circular shape. The plurality of filaments is arranged such that the cross-sectional area of the tuft has a scaled-up shape of the individual filament's cross-sectional area.

  • Publication number: 20150130259
    Abstract: A process for creating multiple tufts for a tufted article comprises directing the initial filament bundle into a first channel, causing the bundle to move through the first channel while splitting the bundle into a plurality of tufts according to a predetermined pattern, and directing the plurality of tufts into the plurality of second channels such that each of the plurality of tufts has its own second channel. An apparatus comprises a first plate having a first channel for receiving a filament bundle, a splitting element for separating the bundle into the plurality of individual tufts, a second plate having a plurality of second channels for receiving the plurality of tufts, and a driving means for moving the filaments in the channels.

  • Patent number: 8915552
    Abstract: A brush head, particularly a toothbrush head, may have a plurality of cleaning elements, in particular bristle tufts, which are anchored by an end section in a brush carrier, wherein the cleaning elements may be cast with positive engagement in blind-hole shaped retaining recesses. For producing such a brush head different cleaning elements, such as bristle tufts may be fused by heat and may be placed in a mold cavity to be over-molded.

  • Patent number: 8845034
    Abstract: A brush head, particularly a toothbrush head, may have a plurality of cleaning elements, in particular bristle tufts, which are anchored by an end section in a brush carrier, wherein the cleaning elements may be cast with positive engagement in blind-hole shaped retaining recesses. For producing such a brush head different cleaning elements may be placed successively or simultaneously in different mold cavities and may be over-molded using different plastic materials from which injection-molding sections of the bristle carrier are formed in the process. In doing so, a first cleaning element is over-molded in a first mold cavity using a first plastic material, while a second cleaning element is over-molded in a second mold cavity using a second plastic material.
