A grass treatment apparatus is adapted to be coupled with a propellant vehicle in order to be movable over the ground and which mounts a plurality of grass treatment units which are engageable with the ground in order to carry out required grass treatment operations. The image data analysis unit is configured to identify a width-directional resolution and a height-directional resolution of image data. The body comprises an expandable form fitting top portion, two lateral side portions, an underside portion, and an elongated heel portion. The invention further relates to the use of a mixture according to the invention as cold-setting binder and the use of said mixtures or reaction mixtures in a no-bake process for producing metal objects. Rotation of the cam by engagement with the slide channel is controlled and an anti-rebound effect is achieved by virtue of the engagement of the leaf spring with the cam. The transparent protective layer is disposed on the patterned UV block layer.
