  • Publication number: 20160097340
    Abstract: A cylinder liner assembly is disclosed for use with an engine. The cylinder liner assembly may have a liner with a hollow, generally cylindrical body extending from a top end to a bottom end along a longitudinal axis. The cylinder liner assembly may also have a seal disposed around the liner at the top end and an anti-polishing ring disposed within the top end of the liner. The anti-polishing ring may have an annular groove formed on an outer surface to provide an air gap between the anti-polishing ring and the liner. The annular groove may axially overlap at least a portion of the seal.

  • Publication number: 20150152494
    Abstract: This disclosure provides a biochip comprising a plurality of wells. The biochip includes a membrane that is disposed in or adjacent to an individual well of the plurality of wells. The membrane comprises a nanopore, and the individual well comprises an electrode that detects a signal upon ionic flow through the pore in response to a species passing through or adjacent to the nanopore. The electrode can be a non-sacrificial electrode. A lipid bilayer can be formed over the plurality of wells using a bubble.

  • Publication number: 20150153302
    Abstract: A biochip for molecular detection and sensing is disclosed. The biochip includes a substrate. The biochip includes a plurality of discrete sites formed on the substrate having a density of greater than five hundred wells per square millimeter. Each discrete site includes sidewalls disposed on the substrate to form a well. Each discrete site includes an electrode disposed at the bottom of the well. In some embodiments, the wells are formed such that cross-talk between the wells is reduced. In some embodiments, the electrodes disposed at the bottom of the wells are organized into groups of electrodes, wherein each group of electrodes shares a common counter electrode. In some embodiments, the electrode disposed at the bottom of the well has a dedicated counter electrode. In some embodiments, surfaces of the sidewalls are silanized such that the surfaces facilitate the forming of a membrane in or adjacent to the well.

  • Patent number: 8359848
    Abstract: An end cap for an exhaust treatment device is disclosed. The end cap has a cylindrical housing with an axial direction, a radial direction substantially orthogonal to the axial direction, a first open end, and a second closed end opposing the first open end in the axial direction. The end cap also has an integral port member extending from an annular surface of the cylindrical housing. The integral port member has a central axis aligned in the radial direction, and an exterior surface of the integral port member tangentially connects to an exterior surface of the cylindrical housing.

  • Patent number: 8146203
    Abstract: The present invention relates to castor wheel assemblies, in particular but not exclusively, to castor wheel assemblies of a type suitable for use with trolleys, for example supermarket trolleys or luggage trolleys. Embodiments of the invention provide a swivel castor wheel assembly configured to support an object to be moved across a surface, the assembly comprising a swivel castor wheel having an axis of wheel rotation and a steering axis and mounted on a first member, wherein the first member is configured for connection to the object in such a way that the steering axis can be moved between first and second different rake angles without substantially changing a height of the object over the surface.

  • Publication number: 20090309090
    Abstract: A nanostructure comprising a first structure comprising conductive material, which is attached to a second structure comprising one or more portions of conductive material separated by insulator material, which is attached to a third structure comprising a material in which a change can be effected. The third structure may comprise a dielectric or ferroelectric material, and the change effected in the material may be polarization of the material. The nanostructure may comprise one or more nanocapacitors, each of which comprises a part of the third structure in which a change comprising polarization may be effected. The nanocapacitors may be used to store data.

  • Patent number: 7255755
    Abstract: A cast stainless steel alloy and articles formed therefrom containing about 0.5 wt. % to about 10 wt. % manganese, 0.02 wt. % to 0.50 wt. % N, and less than 0.15 wt. % sulfur provides high temperature strength both in the matrix and at the grain boundaries without reducing ductility due to cracking along boundaries with continuous or nearly-continuous carbides. Alloys of the present invention also have increased nitrogen solubility thereby enhancing strength at all temperatures because nitride precipitates or nitrogen porosity during casting are not observed. The solubility of nitrogen is dramatically enhanced by the presence of manganese, which also retains or improves the solubility of carbon thereby providing additional solid solution strengthening due to the presence of manganese and nitrogen, and combined carbon. Such solution strengthening enhances the high temperature precipitation-strengthening benefits of fine dispersions of NbC.

  • Patent number: 7153373
    Abstract: A CF8C type stainless steel alloy and articles formed therefrom containing about 18.0 weight percent to about 22.0 weight percent chromium and 11.0 weight percent to about 14.0 weight percent nickel; from about 0.05 weight percent to about 0.15 weight percent carbon; from about 2.0 weight percent to about 10.0 weight percent manganese; and from about 0.3 weight percent to about 1.5 weight percent niobium. The present alloys further include less than 0.15 weight percent sulfur which provides high temperature strength both in the matrix and at the grain boundaries without reducing ductility due to cracking along boundaries with continuous or nearly-continuous carbides. The disclosed alloys also have increased nitrogen solubility thereby enhancing strength at all temperatures because nitride precipitates or nitrogen porosity during casting are not observed.
