The Unconscious is structured like a Language. Lacan borrows some ideas of linguistics that Freud did not have access to. As we have seen, Saussure showed that a sign is not necessarily something that connects a word or name to a thing, but is in fact something which connects a sound or image to a concept. The sound or image is called a signifier.
The rift sawn rip cuts are perpendicular to the center of the log. In woodworking, a rip-cut is to sever or divide a piece of wood parallel to the grain. The other typical type of cut is a cross-cut, a cut perpendicular to the grain. Unlike cross-cutting, which shears the wood fibers, a rip saw works more like a series of chisels, lifting off small splinters of wood.
Tile contractors may create blueprints or lay out tiles on a dry surface to prepare decorative mosaics or patterns. Installers use electric or mechanical tools to cut tiles to go around toilet bowls, pipes and other fixtures. Tiles contractors lay tiles on a flat, clean and level surface. Tile contractors will sometimes install new drywall, tile backer board or another material to a wall, ceiling or floor to be tiled. Concrete floors and other uneven surfaces may need to be leveled with mortar.
