Abstract: An auxiliary insulated roof system for mobile homes, metal buildings and the like includes a generally continuous panel structure of insulation material, a plurality of insulated support blocks for supporting the panel structure in clearance relation above the building roof surface and a plurality of fastening brackets for securing the panel structure to the building sidewalls. The insulated support blocks may include a base plate having a stud extended from one side for penetrating the panel structure and a block of insulation material secured to the opposite side thereof. The insulation blocks may be connected to elongated straps at spaced-apart positions therealong with opposite ends of the straps secured to the building sidewalls for partially securing the panel structure in place. A trim strip covers the fastening brackets and opening between the panel structure and roof surface.

Abstract: An automatic liquid flow control device for use in the application of building insulation foam is disclosed comprising flow meters to measure the flow of resin and foaming agent through conduits to the application gun, a needle valve connected to the resin conduit and operated by a servo motor, a controller to control the servo motor and having a selector to allow selection of the desired ratio of resin to foaming agent, a comparator to compare the actual ratio of resin flow/foaming agent flow to the selected ratio with the controller automatically controlling the servo motor and needle valve to "slave" the resin flow to the foaming agent flow in order to adjust the resin flow/foaming agent flow to the selected ratio. The comparator also compares the actual flow through the resin and foaming agent conduits to predetermine flow values in order to determine abnormal operating conditions.
