Abstract: A shoe horn device which is in the form of a card-like planar structure with one side smooth and the other side with a surface treatment the resists movement, also referred to as the rough side. The device is portable and compact such that it can easily be used to allow the user to put on shoes and then easily be packed away in a wallet or pocket book. The device is also capable of providing a method to present contact or marketing information like a business card, as well as magnetic strip information, like a credit card, rewards card, or gift card. The display device can be constructed of acrylic, plastic, glass, or metal or some other material with similar properties.

Abstract: A fastening system using surfacing on the contact faces of the fastening system components in order to aid in the installation of the system. In addition, the may resemble an installed rivet. The system consists of a bolt with or without an engage-able head. The nut can have a rounded exposed surface resembling rivets. The nut is engage-able through methods to resist movement through surface treatment or tool engage-able surfaces that are not visible. The major application is in that of historic restorations, but can also be used in locations where installation accessibility is limited and/or smooth finishes are desired.

Abstract: The invention is a display device installed on a transporting vehicle. The display device encloses a substance that moves with the inertial “forces” created by the transporting vehicle. The display device can be made up of transparent, translucent, or opaque material. The enclosed material can be gas, liquid, or solid, such as liquid, air, ball bearings, coins, and/or marbles. The device can be installed on the interior (such as ceiling, wall, floor, handles, seats), exterior, or a through structure (such as a window like structure). The vehicle is a device meant to move people or things, such as a train, bus, car, elevator, bike, airplane, gondola, ship, boat, or truck. The device is meant to be observed visually and/or sonically. The device is meant to be used for entertainment, advertising, and/or energy extraction.

Abstract: A spine stabilizing prosthesis has first and second hollow, cylindrical bearing members interconnected by a hollow, cylindrical jacking screw adjustable to expand the prosthesis within a cavity to bridge respective opposite axial ends of the bearing members into pressure engagement with opposing vertebral faces. Walls of the bearing members are perforated by a plurality of bone fragment admitting apertures and forming a bone fragment receptacle so that bone can grow and fuse completely through said bearing members when the prosthesis is installed in the cavity. Respective axial ends of the bearing members are formed with rings of vertebrae engaging teeth having ramp surfaces permitting sliding engagement when rotated in one direction and biting into the facing surfaces when rotated in the opposite direction resisting rotation to permit further expansion apart of the bearing members by rotation of the jacking screw.
