Abstract: A high-efficiency turbine includes low-tensile-strength rotor blades capable of high-temperature operation (such as ceramic) which are mounted on fluid bearings between a continuous rim and a hub, the rim being connected via high-tensile-strength spokes through each blade to the hub. The fluid provides internal support to the blade structure and provides a bearing medium and force with which to maintain blade position under compression. One or more fluids may be employed as coolants in passages within the blade to establish an adequate temperature gradient between blade surface and the associated spoke to minimize spoke failure due to overheating.

Abstract: A substantially dry, impregnated wipe having therein iodine and means for retaining the iodine from escape therefrom, the iodine being present in an amount from about 1% to about 15% by weight of the wipe and in an amount sufficient to provide virucidal activity. The iodine is preferably present in an amount of from about 2% to about 5%. A flexible paper substrate is preferred, and the most preferred substrate is facial tissue. The iodine retaining means is preferably a suitable stabilizing surfactant present in an amount sufficient to complex the iodine, but preferably not substantially in excess of an amount sufficient to complex the iodine. A highly preferred stabilizing surfactant is polyoxyethylene (40) sorbitol septaoleate, present in weight ratio to iodine of from about 1:3 to about 2:1, and most preferably about 1:2.
