Abstract: An adjustable plant pot support for supporting a plant pot on an underlying surface. The support has a substantially rigid body having top and bottom surfaces and an outer perimeter surface. The top surface is adapted to support a portion of the plant pot and the bottom surface is adapted to be seated on the underlying surface. The body has male and female elements that are adapted to be interconnected with the corresponding male and female elements of an additional plant pot support. The supports are vertically stackable and have a retaining wall extending vertically from the top surface to provide a guide against which to place the bottom of the plant pot.

Abstract: A leveling assembly (2) comprising at least two leveling elements (4, 6) and having an uppermost surface (10) for seating a free-standing object 18. Elements (4, 6) are generally wedge-shaped, have upper (10, 14) and lower (12, 16) surfaces angled to one another (38, 42), are adapted to be placed one on the other and rotated relative to one another in order to vary the angle between the uppermost and lowermost assembly (16) surfaces. The elements (4, 6) may have co-operating guiding means (78, 82) or co-operating connecting means (184, 187) to aid in rotating the elements (4, 6) relative to one another and to resist shifting. In addition, the surfaces (16, 56) of the elements (4, 52) may be adapted with concave or cavity portions (58) in order to allow better seating on a surface (8). Reference markings (22, 28) placed on the elements (4, 6) aid in determining a suitable rotation of the elements (4, 6) relative to one another in order to compensate for a given slope.

Abstract: An index system using single axis or multiple axes with single and multiple leaves turning around this axis (axes). All leaves or groups of leaves present an exposed marginal portion obtained by relative extension of leaves and/or partial removal of a portion of the marginal portion (s), which provides an overview of the content, which is indexed in groups and subgroups. Use is made of brief descriptions, capital letters, numbers, arrows and distinctive background color for facilitating the use of the index system.
