Abstract: Improved thermal coupling for a fragile member having a low tolerance to hanical stress is provided by use of thin sheets of common household aluminum foil having impressed thereon a uniform pattern of indentations. The indentations create raised projections which resiliently support the fragile member by the application of a minimum pressure to provide a uniform, non-varying contact therebetween, thereby enabling the mechanical motion therebetween to be absorbed without damage to the fragile member.

Abstract: A rear view mirror having a slidably extensible auxiliary reflective element is disclosed. The auxiliary reflective element serves to enlarge the range of rear view vision of the driver of a vehicle such as an automobile. The position of the auxiliary mirror can easily be adjusted with regard to both its displacement from the principal mirror and the relative angle of its plane with regard to the plane of the principal mirror.
Abstract: The invention relates to a mirror joint assembly. A cover member has opposed detents on its inner surface which mate with complementary recesses on an adjacent clutch member. Threaded studs extend outwardly from the cover member and the clutch member for attaching the joint assembly to supports which are parts of an overall mirror assembly. A spring biases the clutch member and the cover member into an engaged position to retard relative rotation between the clutch member and the cover member.
