    摘要: A solar energy system employing solar panels used to heat water. The system includes a boiler with the vent for the boiler being located beneath the solar panels to distribute exhaust heat thereto. A structure is defined to allow venting of the enclosed area behind the panels. The panels are constructed with multiple sheets of plastic as glazing which are retained by means of interlocking elements and adhesive.

    摘要: A system for space heating for a building employing structural elements of the building as heating conduits. Girder pairs are employed as manifold conduits and joist pairs are employed as distribution conduits for the present system. The crawl space of the building is used for the return air and becomes a plenum therefor.

    摘要: A process is provided for the preparation of 10-deazaaminopterins and 5,10- and 8,10-dideazaaminopterins starting from the corresponding homoterephthalic acid diester coupling the corresponding dicarboxylic acid diester having the formula: ##STR1## with the corresponding diaminopterin 6-methylene halide having the formula: ##STR2## thereby forming a pteroic acid diester having the formula: ##STR3## hydrolysing the two ester groups to form the corresponding carboxylic acid groups, and then monodecarboxylating the diacid, thereby removing the carboxylic acid group attached to the carbon alpha to the A group and forming a pteroic acid.
