Abstract: A planar element storage and display apparatus is provided having an outer box and a carriage slidably mounted therein. The carriage can be pulled from the outer box and a stack of planar elements such as photographs can be placed face up therein. The carriage box is provided with a display window for viewing the upper most element when the carriage carrying the stack of photographs is pushed into the outer box. The outer box is equipped with a detaching means which holds the upper most element and separates it from the stack when the carriage is withdrawn from the outer box. When the carriage is pulled out of the outer box, the upper most element is separated from the stack and drops to the floor of the outer box. Means is provided for placing the dropped element on the bottom of the stack when the carriage is pushed back into the outer box.

Abstract: A drawing material backing (1) is provided which serves to make technical and diagrammatic drawings and is provided on one side with an impressed orthogonal grid (2), which consists of defining pyramid-shaped embossed elevations (8) and has a grid line spacing (3) of 0.5 or 1 millimeter, so that the free-hand drawing of straight lines or of lines intersecting at right angles and with a selected spacing by means of a pencil, ballpoint pen or a paste-applying pen on a paper sheet applied to the backing will be facilitated. To improve the guidance of drawing implements having writing points or writing balls (9, 10) which differ greatly in diameter and to prevent an impression into the drawing paper, the side faces (5, 5a) of the grooves include a steeper angle (6) next to the bottom (4) of the groove and a flatter angle (7) in their upper portion so that the embossed elevations have the shape of pyramids (8) having angled sides.
