Abstract: A dual use or a single use bracket adapted to be mounted on the truss includes an inverted U-shaped portion to mount on the truss, an outward extending portion to connect to the inverted U-shaped portion to mount a shelf. The inverted U-shaped portion is adapted to mount to a floor member, and the duel use bracket includes a flap to mount to the floor member. The outward extending portion includes an aperture for a bolt, and the outward extending portion includes a nut. The inverted U-shaped portion includes a first flap on a front side and a second flap on the back side of the inverted U-shaped portion.

Abstract: An ornamental molding and method of manufacture have a positive molding (1) made of solidified foam material coated with predetermined cementitious-like material having a selected ornamental shape and predetermined resistivity to natural destructiveness. A negative molding (6) in which the positive molding is formed also is made preferably from solidified foam material that is coated with a release agent. The solidified foam material is preferred for its light weight, ease of forming and low cost. Additional advantages of the solidified foam material are long life with coating protection for the positive mold and contrastingly easy destruction and discard of the negative mold after being used to make the positive molding. For a wide selection of ornamental moldings, the positive and the negative moldings can be formed together by parting them from a single piece of solidified foam material with a cutting instrument (8) that can include a hot wire, a hot rod, a fluid jet stream or a laser beam.

Abstract: An operating device for electronic switching devices, which operating device includes a front plate, one or more actuators applied to the from plate for the purpose of actuating one or more modules, a changeable from foil which can be applied to the front plate and which is designed to hold a coding, a recognition system which reads in the data of the coding, and an intelligent control device which picks up the read-in data from the recognition system and assigns, in dependence on the read-in data, a user-specific activation function to each actuator.
