Abstract: According to the preferred embodiments of the present invention, an apparatus and method for retaining keys is disclosed. The present invention provides a tensioning mechanism within the body of the key-retaining apparatus for “pinching” the shaft of a key when the shaft is inserted into the body of the key-retaining apparatus. The tensioning mechanism may take the form of a spring-loaded mechanism or a tensioned piece of metal that is selectively pressured against the shaft of the key when the key is inserted into the body of the key-retaining apparatus. Additionally, a thong or strap may be provided for securing the key-retaining apparatus to a purse, backpack, etc.

Abstract: An apparatus for projecting images simulating the phenomenon of combustion on a display media is provided with a control means for quickly positioning, expanding, and diminishing the images. Light from a light source is passed through orange and grey translucent filter segments, a light dispersal means, and an animating means to project animated orange and grey light images upon the media, the orange light representing the flame component of combustion and the grey light representing the smoke component. The control means comprises a transparent tray situated between the dispersal means and the display media which is overlaid with opaque or translucent particulate material which may be cleared by the finger of an operator or the like from a small area at a selected position on the tray surface to project an image at a corresponding position on the media, the dimensions of the projected image corresponding to the dimensions of the cleared area.
