  • Patent number: 9165584
    Abstract: A slider for a head to read data from or write data to a magnetic media is disclosed. The slider includes an air bearing surface including raised bearing surface(s) elevated above recessed bearing surface(s) to pressurize air flow along the air bearing surface to provide a fly height for the slider above the media. The raised bearing surfaces are formed along one or more raised substrate structures etched from a substrate body. The slider includes one or more insets inset into the one or more raised substrate structures formed of an inset material having a different coefficient of expansion than a substrate material of the slider to compensate for temperature and/or humidity changes.

  • Patent number: 8915717
    Abstract: The impeller wheel is rotatably supported about a central axis and has a hub on which vanes are arranged. The vane has across its radial length at least similar profiled sections, viewed in cylindrical section through the vane. The radial outermost profiled section which is positioned on a cylindrical enveloping surface of the impeller wheel has a greater displacement relative to the neighboring profiled section than this neighboring profiled section to its neighboring profiled section. The impeller wheel can also be provided on the radial outer edge with at least one projecting flow element whose axial height has a maximum in the area of the leading edge and of the trailing edge of the vane. The impeller wheels, while having a simple constructive configuration, provide a great noise reduction in operation of the ventilator.

  • Patent number: 7941947
    Abstract: A snow pusher attachment for use in conjunction with a straight blade angle-type snow plow mounted to a work vehicle. This pusher allows a work vehicle to capture, contain, and relocate large amounts of snow very quickly and efficiently. The attachment consists of side panels, connected by horizontal members between. This pusher attachment is secured to the snow plow by bracket assemblies, attached to the upper edge of the snow plow that engage hooks on the upper, rear portion of the pusher attachment. The attachment does not require the operator to exit the work vehicle to secure or release it from the snowplow. Accordingly, the attachment allows the quick and repeated conversion of a snow plow into a snow pusher box and visa versa.

  • Patent number: 7767130
    Abstract: The invention relates to a method and device for production of a three-dimensional article from a material, by means of layered application. According to the invention, a dropwise application is carried out, whereby drops of reaction components are ejected by a nozzle arrangement (3) and applied to a base reaction component (2), arranged on a substrate (1). The material for the three-dimensional article is formed in layers, with reaction of the base reaction component (2) with reaction components on contact, whereby the material is formed on a reaction of the base reaction component with one of the reaction components to give a material with one material property and on another reaction of the base reaction component with another of the reaction components to give a material with another material property. On production of the three-dimensional article, an article section is produced in which a gradual transition between the one material property and the other material property is generated.
