A fuel injector for gas turbine engines includes an inlet fitting, a housing stem, and a spray nozzle. A pair of fuel passages in the stem deliver fuel in a primary (continuous) flow and a secondary (non-continuous or reduced) flow to primary and secondary discharge orifices in the nozzle. The fuel passages are defined by inner and outer concentric conduits, with the primary flow directed through the inner conduit, and the secondary flow directed through the outer conduit. Fins are provided unitary with the inner conduit along the length of the housing stem, and are fixed at their radial outer ends to the outer conduit. The fins provide structural support and thermally connect the inner and outer conduits. During low power operation, the fins transfer heat energy between the outer conduit to the inner conduit to cool the outer conduit and thermally protect the fuel in the secondary fuel passage.

A foot splint for the prevention and rehabilitation of plantar fasciitis by maintaining a wearer's foot and, hence, his plantar fascia, in a preselected amount of dorsiflexion. The foot splint includes a footplate for supporting the wearer's foot, a lateral strut extending along the lower leg of the wearer and having a strap for releaseably attaching the strut to the wearer's leg, and a wrap for wrapping around the foot of the wearer. A soft insole may be provided to cushion the wearer's foot from the footplate. The wrap, insole and footplate provide a comfortable “slipper-like” feel for the wearer. Moreover, the foot splint is particularly suited for use during sleep since it is light-weight and open configuration allows for the wearer to move unimpeded between sleep positions, resulting in a more restful sleep. Moreover, the lateral placement of the strut keeps the rigid portions of the foot splint from inadvertently abrading, striking, or otherwise interfering with the wearer's other leg.
