Abstract: A secure mobile phone storage and wristband dispensing kiosk includes a support portion and a locker portion. The locker portion includes a plurality of storage compartments and a plurality of dispensing compartments. An authenticator is provided for authenticating the user of an individual storage compartment and dispensing compartment. A series of electronic wristbands are individually stored in each dispensing compartment. A processor is configured to condition unlocking a dispensing compartment upon successful connection of a mobile phone to a charging station in a storage compartment, and to condition unlocking a storage compartment upon successful authentication and installation of one of the electronic wristbands in a storage compartment, thereby allowing a user to store and charge a mobile phone while wearing a wristband that can receive rudimentary communications from the phone.

Abstract: A composite thermal spray powder, for producing abradable coatings, is substantially in the form of clad particles each of which has a core particle of boron nitride and subparticles of aluminum-silicon alloy. The subparticles are bonded to the core particle with an polymeric binder.

Abstract: A tenacious wear resistant coating is applied with a high velocity oxygen-fuel thermal spray gun using a composite powder of aluminum and an iron base metal. The metal may be iron-chromium, iron-molybdenum, cast iron or a combination. A particular combination is a blend of a first powder and a second powder, the first powder consisting of a composite of aluminum subparticles and iron-molybdenum alloy subparticles, and the second powder consisting of a composite of aluminum subparticles and cast iron subparticles. An internal combustion engine block has such a coating applied to the cylinder walls.
