CPC Class B33Y

A teeth cleaning device for simultaneously cleaning multiple teeth, of a user includes a mouth insert for inserting into the mouth of the user, a plurality of cleaning structures attached to the mouth insert or integrally formed together with the mouth insert, a coupling element attached to the mouth insert; and a drive device. The drive device includes a vibration motor, which can be connected to the coupling element such that the vibration motor vibrates the mouth insert during the operation of the teeth cleaning device, and a cleaning program selection element for selecting a cleaning program that defines a vibration frequency of the vibration motor within a specified frequency range and/or a vibration amplitude of the vibration motor within a specified amplitude range. The disclosure further relates to a method for producing such a teeth cleaning device.

An integrated vascular delivery system having a frame configured to receive a catheter insertable in a patient to deliver fluid at an insertion site. The frame includes a first hub, a second hub, and a pair of flexible lateral members extending between the hubs and including a tubular lateral member. The system also includes a fluidic channel that fluidically communicates with the catheter, wherein the fluidic channel passes through the tubular lateral member and at least one of the hubs, and includes a fixed turnabout portion in which fluid flows in a direction different from that within the catheter. The first and second hubs provide anchoring points on the patient distributed around the insertion site and on opposite ends of the catheter, thereby anchoring the frame to the patient and stabilizing the catheter. A method is provided for using an integrated vascular delivery system.

Golf balls and golf ball components made using three-dimensional (3D) additive manufacturing systems are provided. The golf ball includes at least one three-dimensional piece. Preferably, a continuous liquid interface printing method is used to make the three-dimensional structure. Ultraviolet (UV)-light polymerizable materials are used in the method. The method may be used to make single-piece or multi-piece balls. For example, the ball may include an inner core produced by the liquid interface printing method. An outer core layer may be disposed about the inner core, and a cover comprising inner and outer cover layers may encapsulate the core assembly to form the finished golf ball. The outer core and cover layers may be made using conventional molding technologies or the methods of this invention.

Polymeric coatings and methods of forming polymeric coatings are described. In a method of forming a polymeric coating a first layer is deposited on a substrate. The first layer includes at least one highly soluble diamine component. A second layer is formed on the substrate to contact the first layer. The second layer includes paraformaldehyde and an aromatic diamine including two primary amine groups. Once formed, the first and second layers are heated. Heating causes the components of the first and second layers to cure. For example, the paraformaldehyde from the second layer diffuses into the first layer and reacts via hemiaminal-type chemistry with the high soluble diamine component. The coatings may be substantially homogenous or comprise a compositional gradient in thickness or along the substrate plane depending on deposition methods and other processing parameters.

A 3D printing method includes mixing a sintered component which is selected from the group comprising ceramic materials, ceramic material combinations, metal materials, metal material combinations and metal alloys, with at least one surface coating component which is selected from the group comprising boron nitride, graphene, carbon nanotubes, tungsten sulfide, tungsten carbide, molybdenum sulfide, molybdenum carbide, calcium fluoride, caesium molybdenum oxide sulfide, titanium silicon carbide and cerium fluoride, in a powder mixture; and laser sintering or laser melting the powder mixture in a selective laser sintering method or a selective laser melting method.

An additively manufactured assembly including an additively manufactured component with an edge oriented with respect to a recoater blade direction and an non-contact support that does not form a part of the additively manufactured component, the additively manufactured support located adjacent the edge. A method of additively manufacturing a component includes additively manufacturing an component with an edge oriented with respect to a recoater blade direction simultaneous with additively manufacturing an non-contact support that does not form a part of the component, the additively manufactured support located adjacent the edge.
