  • Thermally insulated composite flexible hose
    Patent number: 4399319
    Abstract: A thermally insulated composite flexible hose, particularly suited for heat exchanger connections in building structures, comprising an outer foam jacket of thermal insulation and an inner extended unitary elastomeric extrusion comprising primary tubes spaced apart by an intermediate section separable therefrom along tear lines. The intermediate section may comprise two additional tubes smaller in diameter than the primary tubes. Insulated electrical conductors may be disposed along the outside of the unitary extrusion and inside the jacket.

  • Solar heating apparatus
    Patent number: 4176654
    Abstract: A solar collector simple to install in the field comprises a mat formed of side-by-side extruded EPDM rubber strips having parallel hollow tubes, with inwardly diverging recesses extending along the strips so that the strips can be removably adhered to an insulating base without cement protruding above the tubes. A one-piece extrusion seals an edge of upper light transmissive panel, covers a side of the collector and seals the collector atop a roof or like surface.
