Abstract: The invention relates to catalytic systems which are used to generate colors on a support. The inventive means are characterized in that they comprise one or more deactivated oxidation catalysts. The invention can be used to color organic or inorganic supports.

Abstract: A support system for vertically hanging a flexible banner, the system including two horizontally extending arms for supporting a banner tautly. A dampener is connected at an inner end of each respective arm, the dampener including: a) a movable first element on which is fixed a respective horizontally extending arm; b) a fixed bracket second element for securement to a vertical support surface; and c) an intermediary elastic member mounted between the first and second elements.

Abstract: A foldup grandstand, in which the rows of seats telescope into an unfolded position with the rows of seats available for the spectators, or into a folded position in which the rows of seats are nested one above the other. A series of frames with wheels support the seats, and a V-shaped pieces and frame aligned with a centering finger on an adjacent frame to join the two frames together. The finger has a bent shape and a special head which facilitates its alignment with the V-shaped piece. A self-locking element, rollers, ballast, drivers, cable drives, and an immobilization or locking members are also parts of the grandstand mechanism.

Abstract: Anti-theft device for hoisting or striking a flag or the like (6) along a support structure, in particular a vertical pole (2), with of a halyard (8) interacting with a drive pulley (18) mounted at the upper part of this pole and one end of which links (33) to the upper corner of the flag. In this device the axle (19) of the drive pulley is rotationally controlled, in the direction which rolls up the halyard to hoist the flag or unrolls it to strike the latter, by a reduction motor (21) powered by an electrical energy source (15), controlled via a control circuit from a receiver (25) sensitive to radiation, which is preferably encoded, originating from a transmitter (9) situated remotely.

Abstract: Table flag holder intended to decorate a desk or a table for supporting a pole and banner is provided with a base, and a plurality of inclined surfaces on the base. The plurality of inclined surfaces are constructed and arranged in concentric crowns so that viewing of adjacent flags is not obstructed. Each of the plurality of inclined surfaces includes a series of holes capable of supporting a pole within each hole. Moreover, there is provided a mechanism for radially orienting each of the poles with respect to the base so as to avoid rotation of the pole with respect to the base.

Abstract: This isolation hut intended for temporary or provisional use, notably as a polling-booth during elections or like events, or as a transportable trying cubicle, a dressing-room during occasional events, or the like, consists of a frame structure made from a basic folding sheet of cardboard, pasteboard or light-weight multilayer material, or metal, comprising a plurality of lateral walls and a front access aperture. This structure is stiffened on the one hand by bending the basic sheet material and on the other hand by means of posts disposed at the corners of the structure, a cross bar constituting a lintel disposed at the top of the front aperture, and possibly a desk-forming element, all these elements being obtained by folding a flexible sheet of the same basic material as the basic folding sheet constituting the frame structure.
