Abstract: The invention relates to a support and/or drainage plate made of a foil-like plastic material, for use with a plate-lined floor structure or a wall so as to create a space between the ground and the surface lining to be applied onto the foil-like plate. The structure of the plate is such that cavities are created by means of, on the one side, projections extending substantially in one direction and, on the other side, raised areas at the same level between which chambers are embodied for receiving a hardening contact medium, such as mortar or adhesive, which forms a contact layer with the surface lining to be applied. According to the invention the structure consists of projections (N1, N2) or (S1, S2) which extend in at least two directions and intersect. The resulting chambers (M1) are delimited in their circumference by the projections (S1, S2), which are open towards the other side of the plate.

Abstract: An educational system for teaching individuals their emotions employs a multiplicity of sets of faces. Each set of faces expresses a different emotion experienced by individuals from time to time. The sets of faces have facial expressions correlated to the different emotions. There are a plurality of states of the particular emotion that are expressed in the facial expressions of each set of faces. The states defined for each of the different emotions are subdued, normal and exaggerated states. The facial expressions on the faces employ certain facial features to express the particular emotions, namely, eyes, eyebrows, a mouth and a nose. These facial features are enclosed in a facial circle. The sizes of these facial features relative to the facial circle change from one state of a particular emotion to another and are smallest in the subdued state, largest in the exaggerated state and inbetween and balanced in the normal state.
