Abstract: A self-aligning door stop is taught that consists of a resilient cone shaped body having an apex, a rebated base with a major diameter selected to exceed spacing between a door and a floor upon which the door moves. The rebated base is configured to permit the door stop body to roll into a horizontal position when dropped in proximity of the door. When the door stop is on the floor in any orientation and the door is opened the door stop automatically rolls in the space between the door and the floor thereby self-aligning the door stop. Increasing the door movement retains the door in the desired open position.

Abstract: A card having an information upon which information appears that can be read in the normal manner; a portion carrying a microfilm upon which information is recorded and a portion carrying a lens suitable for reading the microfilm. The card comprises a paper card having an aperture formed in one end region in which is located the microfilm. A pair of flexible clear plastic sheets laminate opposite sides of the paper card including the microfilm. A lens aperture is formed through the clear plastic sheets and through the paper card at an end region opposite the microfilm. A round plastic lens is located in the lens aperture. The lens comprises a central magnifying portion and an outer rim having an outer annular flange. The outer rim is higher than the surface of the central magnifying portion on each side thereof for providing protection for the central magnifying portion of the lens. The lens is secured in the aperture either by ultrasonic welding or by adhesive.

Abstract: A card of size suitable for convenient carrying by a person, for example, in a billfold or wallet, the card having an information portion upon which information appears that can be read in the normal manner, a portion carrying microfilm upon which information is recorded, and a portion carrying a lens suitable for reading the microfilmed portion.

Abstract: A card having an information portion upon which information appears that can be read in the normal manner; a portion carrying a microfilm upon which information is recorded and a portion carrying a lens suitable for reading the microfilm. The card is made from a paper card having an aperture formed in one end region in which is located the microfilm. A pair of flexible clear plastic sheets laminate opposite sides of the paper card including the microfilm. A lens aperture is formed through the clear plastic sheets and through the paper card at an end region opposite the microfilm. A round plastic lens is located in the lens aperture. The lens has a central magnifying portion and two outer annular gripping flanges that grip opposite sides of the card respectively, for securing the lens in the lens aperture. The flanges provide a rim that is higher than the maximum surface of the central magnifying portion on each side thereof for providing protection for the central magnifying portion of the lens.
