Abstract: An integrated method for production of liquid transportation fuels, fuel additives, or chemicals in a biorefinery by the conversion of cellulosic materials is disclosed herein. The method is based on converting a source of C6 sugar such as cellulosic materials and sugars into a mixture of hydrotreated compounds. The biorefinery operates in a unique parallel-processing mode, wherein the initial biomass feedstocks are disassembled to provide substrates for parallel branches whose products may be reassembled in either a condensation step or a mixed hydrotreating step or a final fuel-blending step. The cellulosic materials can be converted to levulinate intermediates that condense with intermediates derived from other processes to produce fuels with the appropriate range of sizes in the target molecular composition, thus generating desirable combustion and physical properties. This method also makes use of methyltetrahydrofuran and other low carbon by-products that are separated for use as amphiphilic solvents.

Abstract: A magnetic storage device comprises an array of magnetic memory cells (50). Each cell (50) has, in electrical series connection, a magnetic tunnel junction (MTJ) (30) and a Zener diode (40). The MTJ (30) comprises, in sequence, a fixed ferromagnetic layer (FMF) (32), a non-magnetic spacer layer (33), a tunnel barrier layer (34), a further spacer layer (35), and a soft ferromagnetic layer (FMS) (36) that can change the orientation of its magnetic moment. The material type and thickness of each layer in the MTJ (30) is selected so that the cell (50) can be written by applying a voltage across the cell, which sets the orientation of the magnetic moments of the FMF (32) and FMS (36) relative to one another. The switching is effected by means of an induced exchange interaction between the FMS and FMF mediated by the tunneling of spin-polarized electrons in the MTJ (30).

Abstract: The present invention discloses a process for sintering particles using a sintering aid. The sintering aid can be brought into contact with a plurality of particles to be sintered such that a mixture of the particles and the sintering aid is provided. The mixture of particles and the sintering aid is heated and at least part of the sintering aid is vaporized. Sintering of the particles to form a sintered component followed by cooling of the sintered component can complete the process, or in the alternative, a subsequent heating step or steps can be included whereby additional vaporization of the sintering aid can occur.

Rollers are mounted on a rigid axle and the axle is engaged by two chains that wrap around chain wheels rigidly attached to the shaft and which are connected to a transverse beam. The front end of the transverse beam is connected to a tensioning device that operates parallel to the platform. Two independently rotating rollers are mounted on the axle on each side of the jack, each roller rests against an auxiliary rail and a guide rail on each inside scissoring leg and the auxiliary rails are inside the jack.
