Patent number: 5540516Abstract: An advertising display method involves marking grass sports fields by bending the grass blades in definite zones and bending or leaving them straight in other zones in order to form an image or a word. The difference in the direction given to the grass blades is quite visible to the spectator. The grass blades are directed by means of an apparatus mounted on rollers which runs on the grass surface. The apparatus also has brushes and/or additional rollers which rotate to straighten the grass blades on definite sectors. The sectors form an image or the letters of a words. The engines which drive the apparatus and the brushes and/or rollers are electrical and are controlled by a computer. The image or word to represent on the grass, as well as the position of the apparatus on the surface to work, are entered in the memory of a computer.Type: GrantFiled: July 27, 1994Date of Patent: July 30, 1996Assignee: Athar International Services SAInventors: Carlo Nicodemo, Ewald Mohring

Patent number: 5531584Abstract: An automated trowelling system for providing a smooth, even finish to one or both sides of a wall. The present system smooths wet surface materials such as concrete or plaster quickly and consistently with minimum manual intervention. Horizontal brackets on the wall support a horizontally translating column and an associated vertically reciprocating trowel. A first motor propels the column and trowel laterally along the wall, while a second motor effects vertical motion. A forward scoop removes excess wall finishing material ahead of the reciprocating trowel, and a nonreciprocating finish trowel follows the reciprocating trowel to provide an enhanced finish to the wall. A processing unit enhances the ability of the system to operate with minimum manual intervention. Sensors provide input to the processing unit.Type: GrantFiled: October 28, 1994Date of Patent: July 2, 1996Inventor: Carol Jacques

Patent number: 5456547Abstract: A machine and method of use to form Sonic Noise Alert Pattern (SNAP) type depressions in the surface of an asphalt road in a series to line the edge or center of a road. The machine installs a plurality of depressions in a group during a single cutting procedure. A repetition of these cutting procedures results in the desired series being formed. The machine has a single rotary type milling head with spaced sets of bits which will engage the surface of the road. Only where the spaced sets contact the surface will the cutting action be performed. From a stationary position an initial plunge cut brings the rotary cutting head in contact with the surface. Then a lateral movement of the rotary cutting head results in elongating and forming the desired sized depressions. Then the rotary cutting head is raised, the machine is advanced and the prior steps are repeated in repetition until the desired number of depressions have been formed.Type: GrantFiled: January 11, 1994Date of Patent: October 10, 1995Inventors: Glen E.

Patent number: 5435662Abstract: Marker devices, each comprising a base with an upright post thereon, are molded from an elastomeric material. A marker device is attached by adhesive on the base thereof to each paint striping on a worn down street and each maintenance cover mounted on the worn down street. Once the marker devices are in place on the worn down street, the posts thereof must withstand the punishment of not only being flattened by truck tires, and the tracts of a paving machine that is being used to lay down the new coating of hot asphalt on the worn down street, but also the hot asphalt, and still spring back to their upright position. Thus, when the stripings are to be repainted on the resurfaced street and when the maintenance covers are to be adjusted upwardly to the level of the new coating of asphalt on the resurfaced street their exact locations on the street are immediately indicated by the posts of the marker devices without having to make any measurements.Type: GrantFiled: September 21, 1993Date of Patent: July 25, 1995Inventors: Donald M.

Patent number: 5039557Abstract: A method and apparatus for applying or re-applying retro-reflective glass beads to in-place thermoplastic pavement marking lines. A heated container warms the beads to a temperature below their melting point but above the melting point of the line. The heated beads are then uniformly dispersed onto the surface of the line. Heat from each bead is thereby transferred into the surrounding thermoplastic material, causing the material to melt and the bead to adhere. The beads are then embedded into the thermoplastic by suitable means such as a roller. By adjusting the temperature of the beads and/or the downward force of the rollers, the depth of the embedded beads can be controlled for optimum reflectivity and adhesion, and variations in ambient operating conditions can be accommodated. The line is usable by traffic essentially immediately after bead application. The same apparatus can be used to apply beads of varying sizes.Type: GrantFiled: October 26, 1989Date of Patent: August 13, 1991Inventor: Terrence H. White
