Patent DE-4040839-A1 (DE)
Inventor: SCHLENKE HUBERT
IPC: B60R1/08
Filed: 1990-12-20
Abstract: The invention concerns a vehicle rear-view mirror (1) comprising a plane-mirror section (2) and at least one convex section (3, 11) contiguous with the sides of the plane section. The curvature of the convex side sections is zero at the transition lines (4, 12) with the plane-mirror section (2), and increases progressively with increasing arc length (L) from the transition line, the curvature of vertical orthogonal lines of intersection being equal to the curvature of a horizontal reference line (6, 6A) at their point of intersection. The rear-view mirror (1) proposed enables the driver to view both behind and to the side. The mirror (1) is easy to produce since the curvature of the convex side sections (3, 11) only departs by a small amount from the plane of the plane-mirror section (2).

Abstract: The method includes the step of subjecting an air-dry positive or negative active-mass or a mixture of these to heat-treatment at a temp. of 500 to 700 deg. C for 8 to 60 minutes, then either grinding the heat-treated active-mass in a known manner or feeding it into a lead-powder mill in an amt. of at most 80 percent by mass, calucated on the mass of the lead charged into the mill, and in both cases grinding to an average particle size of less than 60 micrometres.
