20090123324Iron-Base Alloy Containing Chromium-Tungsten Carbide And a Method Of Producing It - A method and cast wear resistant component made of an alloy that includes carbon, tungsten, chromium, and cobalt with the balance essentially iron and other alloying components made using waste, surplus or worn-out cemented carbide product, such as cemented carbide cutting tool inserts. In one method, the alloy further includes silicon, manganese, nickel, titanium, and molybdenum. In practicing the method, pieces of waste, surplus or worn-out cemented carbide product having tungsten carbide (WC) are added to a cast iron alloy melt. The melt includes enough chromium to control solubility of the WC. In one method, precipitated carbide structure having chromium and carbon is produced with tungsten in the melt being substitutionally dissolved. In one implementation, tungsten is substitutionally dissolved in a lattice of the precipitated carbide structure. Carbide can be added to the melt via super inoculation. The cast wear resistant component can be a cutting tool.05-14-2009

20100179375VIBRATOR FOR BONE CONDUCTING HEARING DEVICES - A vibrator for generating vibrations in a bone conducting hearing device, i.e. a hearing device of the type in which the sound information is mechanically transmitted via the skull bone directly to the inner ear of a person. The vibratory movements are provided by a piezo-electric or magneto-elastic element arranged to transfer the vibrations via the skull bone from the area behind the outer ear to the inner ear. The piezo-electric or magneto-elastic element is arranged to be at least partially implanted in a surgically drilled hole directly into the mastoid bone behind the outer ear so that the vibrations are transferred directly from the element to the bone and transferred in the skull bone to the inner ear. The element is encapsulated with a bone integrating material, such as titanium or various biocompatible ceramic materials or coatings and is disc shaped and acts with a radial expansion upon electrical stimulation so that longitudinal sound waves are induced into the skull bone.07-15-2010
