Abstract: An electronic device includes a body including first and second sections selectively adaptable between open and closed positions. Each section has a linear edge defining an axis about which the sections are pivotal. The first and second sections are coextensively shaped. Mechanisms are included for digitally storing and displaying photographic images and digitally storing and displaying personal contact information, and are housed within the first body section. A mechanism is included for locking the sections at a closed position, and includes a speaker and a transceiver communicating therewith for emitting a distress signal when an unauthorized user attempts to access the device. Money bill and a credit card holding sections are connected to the second section. The credit card section lies on top of the money bill section when articulated to a stored position. An internal power supply source is coupled to the contact and image storing and displaying mechanisms.

Abstract: A catalyst support comprises a porous gel of an inorganic substance, for example a refractory inorganic oxide, and has a surface area in the range 125 to 150 m.sup.2 /g, a mean pore diameter in the range 140 to 190 .ANG. with at least 80% of the pore volume contained in pores having a pore size range of 50 to 90 .ANG.. The invention also relates to catalysts based on such supports and to hydrocarbon conversion processes, for example reforming, carried out in the presence of hydrogen and employing said catalysts.

Abstract: Hydrocarbon hydroconversion, especially hydrocarbon reforming, using catalysts whose supports have been prepared by a sol-gel process. For hydrocarbon reforming, it is preferred that the primary particles used to prepare the porous gel should have been prepared by a vapor phase condensation method, for example flame hydrolysis and that the support should have a narrow pore size distribution. The process produces much less gas by hydrocracking at given aromatics yields than comparative processes using conventional catalysts.
