  • Patent number: 10407335
    Abstract: A system for levitating a softened, viscous or viscoelastic material by near field acoustic levitation. The system includes a support structure having a rigid surface, and a vibration generator operatively connected to the rigid surface. The vibration generator transmits acoustic waves to the rigid surface at a frequency and an amplitude sufficient to vibrate the rigid surface and create a gas squeeze film between the material and the rigid surface. The gas squeeze film has a pressure greater than ambient air pressure and sufficient to levitate the material. The system is particularly suited for transporting, forming, or casting heated glass. Also disclosed are methods for transporting, forming, and casting heated glass using near field acoustic levitation.

    Abstract: The invention concerns a process for the layerwise production of a product comprising the steps of applying a layer of a hardenable material, wherein for example the process parameters of layer thickness and layer material are adjustable, selectively hardening predetermined regions of the applied layer on the basis of the geometrical data of the product, wherein for example the process parameters for the nature and level of the energy input are adjustable, repeating those steps until the geometry of the product has been produced in the form of hardened material, and finally removing the non-hardened material. Known processes suffer from the disadvantage that they do not afford variability in regard to the local properties of the product. The invention remedies that disadvantage insofar as at least one process parameter is altered during the production procedure in order to influence the grain size in a first region of the product in relation to a second region of the product.

    Abstract: A method of making a composite material, the method comprising: providing a tile, wherein the tile comprises an inorganic material; and bonding the tile to a ductile backing material using heat-curable adhering material and catalyzed foamable exothermic material between the tile and the ductile backing material, wherein heat generated from the use of the catalyzed foamable exothermic material cures the heat-curable adhering material. In some embodiments, the exotherm from the foaming of the foamable exothermic material cures the heat-curable adhering material for a time sufficient to unite a solid foam body to the heat-curable adhering material of the tile and the ductile backing material. The method is particularly advantageous in bonding a tile composed of nano-particles to a ductile backing material, as it helps retain the nanoscale properties of the nano-particles in the tile.

  • Patent number: 8349040
    Abstract: The present invention relates to polycrystalline ultra hard material cutting elements, and more particularly to a method of forming a polycrystalline ultra hard material cutting element with a thicker ultra hard layer than cutting elements formed by prior art methods. In an exemplary embodiment, such a method includes pre-sintering the ultra hard material powder to form an ultra hard material layer that is partially or fully densified prior to HPHT sintering, so that the ultra hard layer is pre-shrunk. This pre-sintering in an exemplary embodiment is achieved by means of a spark plasma process, or in another exemplary embodiment by a microwave sintering process.

  • Publication number: 20120267830
    Abstract: Rapid sintering techniques for densifying zirconium dioxide based ceramic materials employing electromagnetic induction heating or inductive coupled plasma, reducing processing time from hours to minutes. In one embodiment a water-cooled coil is connected to a radio frequency power supply. The coil surrounds a susceptor body which in turn surrounds the ceramic to be sintered. The susceptor heats up in response to a magnetic field emanating from the coil as the coil receives electric power. The heat in turn is radiated from the susceptor and heats the ceramic. In another embodiment, the coil is connected to a radio frequency power supply of sufficiently high frequency and power to establish a plasma in the gas which surrounds the ceramic. The plasma then heats the ceramic. The method is especially useful for sintering ceramic dental appliances, in minutes which can lead to in situ fabrication of such appliances while a dental patient waits.
