The present invention provides a novel adsorbent carbon supported activated alumina which posses both the advantageous characteristics of carbon and alumina viz. The mechanism also includes a cache controller configured receive a transaction request including an address and to generate an index for accessing the storage by performing a hash function on the address. The reference points A-D have associated respective roll angles, \u03b5A-D, between a corresponding first line that is perpendicular to the involute surface at the given reference point A-D and a second line that is tangent at a reference point that lies on a terminal end of the involute surface at the tooth base to a reference base circle having a center origin at the center axis. In addition, a list of property record attributes such as owner, use code, assessed value and year constructed can be displayed. 11 packet includes a preamble portion, a header portion and a data portion.
