    • The present invention relates to a highly processive reverse transcriptase having DNA polymerase activity and substantially reduced protease activity. More specifically, the invention relates to an isolated reverse transcriptase from foamy virus comprising a substantially inactivated protease. The invention also relates to vectors containing the gene and hosts transformed with the vector of the invention. Further, the invention relates to a method for producing reverse transcriptase having DNA polymerase activity and substantially reduced protease activity by expressing the reverse transcriptase genes of the present invention in a recombinant host. Methods are also provided for producing cDNA from polynucleotides using the highly processive reverse transcriptase of the invention. Kits for the preparation of cDNA from RNA comprising the highly processive reverse transcriptase of the invention are also provided.

    • A mechanism for sensing the changing positional and orientation of a hand held device as it is moved by the device user to control the state or operation of the hand held device and one or more vibrotactile transducers positioned on the body of the hand held device to provide haptic feedback stimuli to the user indicative of the state of the device. The mechanism employs the combination of accelerometers for obtaining inertial data in three degrees of freedom, gyro sensor for obtaining roll, pitch and yaw angular motion data, a GPS system for providing position data, and magnetometers for providing directional data. This sensor data may be used to control the functioning of the hand held device; for example to control display scrolling, and the vibratory stimuli fed back to the user provides an indication of the effects of the gestural movements the user imparts to the device.

    • A process for producing iron metal and slag by smelting iron-containing source material, having iron present as oxide and/or a partially metallised state, in a reactor containing a molten bath comprising or having a slag phase, utilises injection of fuel/reductant and oxygen-containing gas into the slag, by at least one top-submerged lance, to generate heating and reducing conditions in at least one reducing region in the bath. The source material is fed to the reactor, together with additional reductant and with flux, at or adjacent to the at least one reducing region, to subject the source material to smelting reduction which generates combustion gases comprising CO and H2. The rates of injection of the oxygen-containing gas and fuel/reductant by said at least one lance are controlled to achieve required, sufficient reducing conditions; and, in the reactor above the bath, the combustion gases generated by the smelting are post-combusted. The controlling of step (c) is conducted to result in the injected oxygen-containing gas having an oxygen content of from about 40 volume % to about 100 volume % and sufficient for a degree of combustion in excess of 60 wt % of the fuel/reductant injected by the at least one lance.
