SiO2, Al2O3, AlSi-oxide, NiSi-oxide, MgO or oxyfluorides of the same gp. of metals., esp. MgF2, and featuring a low refractive index of not more than 1.7. Between the nitride layer and the previous layer pref. an adhesion promoter is used, e.g, Ni or NiOx with x less than 1, alternatively Cr or Cr-suboxide, or a NiCr alloy with 20 wt. % Cr and 80 wt. % Ni or a suboxide of this alloy. Also claimed is the use fo a first layer of a NiCr-suboxide. On the back surface of the substrate pref. a TiNx layer is deposited with a value of x not less than 1. The first layer pref. is 8 nm +/- 20% thick, the second layer pref. 13nm +/- 20% and the third layer an optical thickness of 555/4nm +/- 10%.

Patent DE-4014943-A1 (DE)
Title: Lever for operating motor vehicle window - has bearing formed from metal with boss raised on one side
Inventor: KUEHN BERTHOLD
IPC: E05F11/44
Filed: 1990-05-10
Abstract: The lever for actuating the sliding window of a motor vehicle is formed from sheet metal. The lever rotates in a bearing formed by a boss which is a running fit in a hole in the structure which supports the lever. The boss is formed by stamping a depression on the side of the lever opposite to the boss. Such a boss usually has a relatively large edge radius which reduces the bearing area. This edge radius is reduced by stamping an annular groove (2) near the edge of the boss so that metal is forced radially outwards and an edge with a small radius (r) is formed. The annular groove can be used as a grease reservoir for lubricating the lever bearing. This method of producing a bearing can be used for any slowly rotating mechanism. USE - Levers for operating motor vehicle windows.

Title: Process for accelerating and synchronising seed germination - involves hydrating and dehydrating original seed stock to raise moisture content
Inventor: WHITE DONALD B
IPC: A01C1/02
Filed: 1990-08-29
Abstract: Before drilling, an initial stock of seeds are brought into contact with water until the moisture content of the ensuing stock of hydrated seeds is higher than the original moisture content of the stock.
