Abstract: An integrated transmission and helicopter rotor head is disclosed. Lift and bending moments generated by the rotating hub are carried by non-rotating support structure. The rotating rotor shaft is adapted to carry only torque loads. Partial gear reduction takes place above the rotor shaft, thereby reducing its torque loading. The invention includes a planet gear assembly wherein the ring gear is connected to the rotating hub, while the rotor drive shaft causes rotation of the sun gear. The hub swashplate is located above the hub with its control rods passing through the planet gear assembly.

Abstract: An apparatus for storing and dispensing a continuous band of medical reagent test strips is disclosed which includes chambers for the storage of used and unused portions of the continuous strip separated by barrier member to prevent cross-contamination there between. A substantially flat interim space is provided between the accesses to the chambers wherein tests may be run utilizing the samples in conjunction with the strips. Mechanical means is provided for advancing the band of medical test strips as necessary. The apparatus may be fabricated of suitable, moldable plastic material which may be discarded after the band of unused medical reagent test strips is exhausted.
