| 20110212303 | PDC Cutter with Stress Diffusing Structures - A PCD cutting element for use in earth boring drill bits where the interstices remote from the working surface are filled with a catalyzing material and the interstices adjacent to the working surface are substantially free of the catalyzing material is described. An intermediate region between the substantially free portion and filled portion has a plurality of generally conically sectioned catalyst-free projections which taper down, extending to a second depth from the planar working surface, preferably about 0.5 times or more of the first depth. | 09-01-2011 |

| 20110031028 | Hard Composite with Deformable Constituent and Method of Applying to Earth-Engaging Tool - A hardmetal composite used as wear-resistant surfaces and inlays in earth-engaging equipment includes more than one hardphase. At least one hardphase has a high average particle size, for example, from 100 μm to 2000 μm. The hardphases vary in terms of particle size, hardness, and binder content, and at least one hardphase includes a particulate constituent capable of plastic deformation that comprises at least 1% residual porosity. | 02-10-2011 |

| 20110117294 | Biofouling prevention by induction heating - An apparatus and method for heating target surfaces to a temperature that inhibits, prevents or removes biofouling through induction heating includes an electromagnetic driver and control circuitry for generating electromagnetic energy within a select frequency range to match a target surface. An antenna emits the electromagnetic energy within a focused region to react with atoms/molecules in the target surface, thereby causing the target surface to be heated to a temperature within a controlled range. Increasing temperature sufficiently disrupts, kills or denatures biofouling organisms, biofilms and organic matter on the target surface and/or denatures biofilms on the surface. Coating materials may be applied to target surfaces to optimize the RF reactive molecular structure. A diagnostics, positioning and temperature sensor circuit communicates with the electromagnetic driver. A feedback circuit is used to maintain power level. Contemplated heating mechanisms include: magnetic hysteresis; dielectric hysteresis; eddy currents; and enhanced skin effect. | 05-19-2011 |

| 20100113701 | ORIENTED THERMOPLASTIC ELASTOMER FILM AND PROCESS FOR PRODUCING THE SAME - An oriented thermoplastic elastomer film having reduced permeability and improved fatigue resistance comprising a dynamically vulcanized polymer blend of (A) a halogenated isobutylene elastomer and (B) polyamide, the film is produced by casting or blowing the above polymer blend under the condition such that a shear rate at a die lip for casting or blowing is regulated to control the molecular arrangement in the film, whereby the planar birefringence (PBR) of the resultant film becomes greater or equal to 0.002 and a production process of the same. | 05-06-2010 |

| 20120015182 | Adhesive Extrusion For Dynamically Vulcanized Thermoplastic Elastomer Laminates - A coextrusion process for coextruding a thermoplastic elastomer with two outer layers of adhesive to form a film, and a laminate comprising a plurality of layers including an adhesive layer, a sublayer and a barrier layer. The barrier layer comprises a dynamically vulcanized thermoplastic elastomer composition present in one or more plies of the barrier layer. The sublayer comprises a first ply of a first adhesive composition joining the barrier layer and a second ply, and the adhesive layer comprises the second ply, which is vulcanizable with diene-based rubber. The sublayer of the adhesive can be laid down in contact with the relatively hot thermoplastic elastomer to moderate the temperature of the outer layer of the adhesive, whereby the outer layer of the adhesive at least is protected from scorching and can be co-vulcanized with rubber in a tire building process. | 01-19-2012 |

| 20100085186 | Tamperproof Non-Contact Switch - A non-defeatable magnetically actuatable switch device is shown and described for restricting access to industrial controls. The non-contact switch device employs one or more non-contact access switches, and an access key removably disposed in close proximity to each access switch. Removal or installation of an access key alters the electrical state of a corresponding access switch. A connected control unit determines a mode of operation, or grants permissions, based on the combination of access keys that are present or absent from the device. A lockable or sealable cover is provided over the access keys to limit unauthorized access. A tamper detection switch is also provided for the sole purpose of identifying foreign magnetic sources in the vicinity of the access switches to ensure that the device is non-defeatable. Furthermore, all access and tamper detection switches are magnetically actuatable and thus provide a completely contact-free means of securing and restricting access to sensitive controls and parameters. | 04-08-2010 |
