Abstract: A portable chart holder for use in open or exposed positions which provides protection from the elements and easy visual reference to contained charts is disclosed. The chart holder generally comprises a base panel surrounded by and integrally locked into a frame, a transparent cover designed to fit the configuration of the base panel-frame assembly such that a chart containing enclosure is formed between the base panel and the cover, and easily disengagable fastening means disposed at intervals about the periphery of the cover adapted to removably affix the cover to the frame such that the chart containing enclosure is substantially isolated from the effects of the elements.

Abstract: A monitoring system for the notification of locations external to the area being monitored of a prolonged absence of motion within the area being monitored is disclosed consisting of a clock, an electronic counter designed to record the pulses emitted periodically by the clock and to signal an alarm trigger when a pre-programmed number of pulses are recorded, and reset means such that if activated the counter will return to zero thereby preventing activation of the alarm trigger. Also, this system uses circuit means incorporating a photoelectric cell to automatically increase the pre-programmed number of pulses necessary to cause activation of the alarm trigger during periods of darkness and to automatically return the counter to its original pre-programmed condition with the presence of light.

Abstract: A process for the preparation of alcohols from purified carbon, including the step of hydrogenating the carbon at high temperature and pressure in a catalytic reactor in a dispersion with naphthalene and in the presence of a catalyst comprising nickel, ruthenium, aluminum and cobalt molybdate, and the step of oxidizing the resulting paraffins by contact with steam at high temperature and pressure in a catalytic reactor in the presence of a catalyst comprising a mixture of silica and copper and the oxides of zinc, chromium and boron. The catalysts are suspended in a ceramic concrete aggregate, extending the length of the reactors and in the form of a cylindrical reactor liner and a smaller, concentric ceramic cylinder therewithin. The second step is performed in two reactors in series.
