  • Patent number: 9688059
    Abstract: An inflatable or gas-filled insulation panel comprises an envelope having two outer sheets sealed together along edges of the sheets and at least one of the sheets has an outer reflective surface. The envelope encases a plurality of internal films that include a polymeric film having a plurality of reflective stripes disposed thereon and spaced apart on the films. Seals are formed along the gaps or areas between the reflective stripes on the films by application of heat and pressure, which causes the films to seal to each other and the outer sheets at spaced apart intervals. A channel is formed between the outer edges of the films and the outer sheets, and a valve, disposed at an end of the panel, is in fluid communication with the channel for the injection of a fluid, such as an inert gas or air, to inflate panel.

  • Publication number: 20170169845
    Abstract: A method, according to one embodiment, includes writing a plurality of shingled tracks using an array of writers. The array of readers is repositioned to various locations between first and second positions and data is read from the shingled tracks at the various locations. A read offset point where read performance is about the highest during the reading performed when repositioning the array of readers between the first and second positions is determined. The method includes computing, using the read offset point, data describing a lateral writing position to use during writing such that shingled tracks are written in a location specified by a format. As a result, methods according to the present embodiment are able to provide desirable track alignment and reduced readback error rates for data of shingled tracks written to magnetic medium.

  • Patent number: 9630840
    Abstract: Various embodiments disclosed relate to cooling shale gas via reaction of methane, light hydrocarbons, or a combination thereof, with water. In various embodiments, the present invention provides a method of cooling syngas. The method includes contacting the hot syngas with methane or light hydrocarbons. The hot syngas includes water and has a temperature of about 800° C. to about 3000° C.

  • Publication number: 20170032817
    Abstract: In one general embodiment, a method includes calculating a differential position value based on readback signals from at least two servo readers of a magnetic head reading servo tracks of a magnetic recording tape. The differential position value is compared to a previously-calculated differential position value. An action is performed in response to determining that the difference between the differential position value and the previously-calculated differential position value is in a predefined range. In another general embodiment, an apparatus includes a magnetic head having at least two servo readers, and a controller in communication with the servo readers. The controller is configured to detect a sudden change in a width of a magnetic recording tape based on a differential position value derived from relatively more current servo readback data and a second differential position value derived from relatively older servo readback data.
