Title: Road having curved grooves
Inventor: WHITNEY JAMES R
IPC: E01F9/053
Filed: 1988-07-15
Granted: 1992-05-05
Abstract: ABSTRACT OF THE DISCLOSURE            An apparatus and method for cutting grooves on the edges of an already formed road.  Each of a plurality of toothed cutting wheels revolves about a  substantially  vertical  driving  shaft. Simultaneously, each cutting wheel (attached to a respective rotary shaft) revolves about its own longitudinal and substantially horizontal axis. The apparatus is moved along a road, near an edge thereof, thus giving rise to one linear motion and two rotary motions.  Sequentially, each cutting wheel enters an edge of the road from a region beyond the road edge, due to a slight tilt of the plane which contains the cutting wheel rotary shafts.  The resultant grooves are deepest at the road edges and then gradually diminish to zero depth, the grooves being arcuate and parallel to each other.  With the plane containing the cutting wheel shafts completely horizontal, the apparatus can cut rain drainage grooves in a raised marking strip on the road or can remove bumps from the road.

Abstract: ABSTRACT OF THE DISCLOSURE           SLIDING ROOF OR SLIDING LIFTING ROOF FOR MOTOR VEHICLES     In  a  sliding  roof  or  sliding  lifting  roof for motor vehicles,   the   lateral  guide  rails  for  the  sliding guidance  of  the  rigid cover and the roof frame carrying the  same  are  entirely  located  below the fixed vehicle roof  and  are  fitted  closely  adjacent thereto, so that neither  the  roof  frame,  nor the guide rails can reduce the   free   opening  cross-section  of  the  roof  cutout releasing  the  cover following its opening.  As the water channel  for  collecting  the  water  penetrating  via the marginal  gap  between  the cover and the roof cutout edge is  fixed only at a limited distance below guide rail, the overall  height  of  the roof construction can be limited. As  a result of the elastically deformable construction of the  edge of the water channel facing the roof cutout, the guide  parts  of  the cover or, in the case of the sliding lifting   roof,   the   intermediate  frame  can  pass  in unimpeded  manner  through  the elastically expandable gap between   the   roof   cutout  edge  and the  elastically deformable water channel edge to the guide rails.
