  • Device for manufacturing a heating glass plate
    Patent number: 4436575
    Abstract: A heating glass plate (15, 20, 27, 34) has a heating network (17, 24, 31, 36) made up of wires embedded in a thermoplastic layer following curved directrices. A device for making a heating glass plate having a plate (39) for supporting thereon a plastic sheet. A bridge (44) is slidably supported on the plate and has thereon a sliding carriage (45) carrying wire-laying members (46). Means are provided for imparting reciprocal motion to the carriage. A rod (51) connects the carriage to a vertical spindle (52).
    Type: Grant

  • Process for manufacture of solar photocell panels and panels obtained thereby
    Patent number: 4321418
    Abstract: A panel of a plurality of electrically connected photocells wherein each photocell has a lower face, a side face and a radiation receiving face, is produced by (a) embedding at least the lower faces and side faces of the photocells and their electrical connectors in a thermoplastic resin in particulate form which resin becomes transparent upon fusion; (b) enclosing the photocells embedded in step (a) between two rigid sheets to form a sandwich-type assembly, with at least the rigid sheet enclosing the receiving faces of the photocells being optically transparent; (c) disposing the stacked assembly formed in step (b) within a flexible bag; (d) subjecting the interior of the flexible bag to a vacuum while applying relatively high pressure to the outside of the bag, and raising the temperature within the bag to fuse the thermoplastic resin particles; and (e) cooling the contents of the bag to solidify the resin and form thereby the panel comprising the photocells adhesively embedded in the solidified resin betwe
