Abstract: A method of co-firing fuel within a gas turbine engine. The method may include injecting a first fuel into a combustion system of a gas turbine engine. The first fuel may include a high energy liquid fuel. The method may also include injecting a second fuel into the combustion system. The second fuel may include a gaseous low Wobbe fuel. Only the first fuel may be injected during a first mode of operation. The first fuel and the second fuel may be injected simultaneously and discretely during a second mode of operation.

Abstract: The invention provides a support structure (1) for a mobile communications device (100) comprising a dampening mechanism (400) to dampen the insertion of the mobile communications device into the support structure (1) wherein the dampening mechanism comprises a geared arrangement to control the speed of insertion of the mobile communications device (100) into the support structure. Such a support structure (1) provides a controlled speed on insertion of the mobile communications device (100) and this controls the impact of the mobile communications device (100) with the support structure (1). Potential damage to the support structure (1)/mobile communications device (100) is reduced.

Abstract: A torque reduction assembly for use with an archery bow having a central riser includes a grip having a front surface adapted to be in contact with an archer's hand and a coupling for mounting the grip to the riser that allows a predetermined amount of rotational movement of the grip with respect to the riser along two axis while maintaining alignment between the grip and the riser along a third axis. The two axis of movement include a vertical axis generally extending along the length of the riser and a horizontal axis generally extending perpendicular to the riser and parallel to the front surface of the grip.
