A transmission apparatus which prevents adversely affects from an adjacent channel even without provision of a guard band. A value of infrared energy reflected from the metallic substrate without the sol-gel coating is determined. The filter elements of the filter assembly filter the turbulent flow. Protected access by the session processes is provided by granting access to one of the two or more interleaved caches only after one of the plurality of session processes performs a semaphore altering read-modify-write operation on the particular semaphore. A predetermined value is optionally stored at a destination based upon the outcome of the comparison. These viscous compositions are made of a mixture of a water soluble hair binding agent, a water soluble cross-linking agent for the hair binding agent, and a water soluble crystallization inhibitor agent, whereby the cross-linking of the hair binding agent by the cross-linking agent results in water washable hair binding compositions that do not crystallize during their use or storage.
