  • Publication number: 20150159320
    Abstract: An imitation leather fabric formed from a basis fabric, wherein the basis fabric includes a first fabric layer including a first set of fibre elements and a second set of fibre elements woven together to form a plain weave or a twill weave. The basis fabric of the imitation leather fabric also includes a second fabric layer facing the first fabric layer. The second fabric layer includes a third set of fibre elements woven together with the first set of fibre elements to form a long loop blister weave.

  • Publication number: 20130277227
    Abstract: An apparatus for producing pure silicon from an electrolyte including a first crucible for receiving the electrolyte, a heat source for heating the electrolyte in the first crucible to form a molten electrolyte, an anode and a cathode which are adapted for electrical/ionic communication with the molten electrolyte wherein electrolysis is able to be applied to the molten electrolyte when a potential difference is provided between the anode and the cathode. A stirring device is adapted for stirring the molten electrolyte when electrolysis is being applied whereby pure silicon is produced which is soluble with the anode to form an alloy.
