  • Vehicle sunroof installation
    Patent number: 4333680
    Abstract: This invention relates to a method of installing a sunroof in a vehicle which is characterized by the use of an adhesive to bond the sunroof to the vehicle roof. In the preferred embodiment certain mechanical devices are employed in conjunction with the adhesive to reinforce the bond of the sunroof to the roof of the vehicle. For example, mechanical devices, such as U or L trim rings in conjunction with the adhesive not only reinforce the bond between the vehicle roof and the sunroof, but also beautify by hiding the marred edges of the cut-away roof, as well as sealing the raw metal cut-away metal edges from moisture and corrosion.This invention also relates to the combination of the sunroof installed in the vehicle in the above manner.

  • Electrical resistance corrosion probe
    Patent number: 4326164
    Abstract: An electrical resistance corrosion monitoring probe having a single lateral face of each of two rectangular prismatic elements of similar temperature-resistance characteristics but different thicknesses exposed to the corroding environment. Both the faces are corroded away, but the resistance change is different due to the inverse relationship between resistance and cross-sectional area. A measurement bridge network is used to monitor the change in cross-sectional area of both elements. A preferred probe embodiment, employing resistance elements having equivalent thermal masses and electrical resistances, as by using elements of the same material and of substantially equal lengths and cross-sectional areas, allows the use of a complementary measurement bridge network in its most sensitive region.
