Title: Abrasion resistant steel - for scraper teeth of earth moving machine esp. bulldozer
Inventor: SATSUMABAYASHI KAZUYOSHI
IPC: C22C38/22
Filed: 1977-01-15
Abstract: Steel contg. C 0.25 - 0.40, Si 1.50 - 2.50, Mn 0.50 - 1.60, Cr 3.00 - 5.00, Mo 0.50 - 1.20 wt.%, balance Fe, is highly abrasion-resistant under the conditions of bulldozer operation. The steel may even further be improved by adding Nb 0.01-0.10 and/or V 0.20-1.50 wt.%. The C level is critical, because higher C contents than 0.4% lower the Charpy nothc impact toughness below 5 kg. m/cm2. The Cr level is also critical as it should be higher than 3 wt.% in order to obtain the required hardness, but it should not exceed 5 wt.% as the Charpy notch impact toughness will then be too low.

Patent DE-2817966-A1 (DE)
Inventor: LUEF HEINZ
IPC: E05B19/00
Filed: 1978-04-24
Abstract: In known master-key systems, the cylinder cores have a key channel with a guide profile. The guide profile serves only for fixing the reference plane during the sensing of the profile and remains unchanged. The invention provides a master-key system, in which the key and key channel have three profile segments, seen in cross-section. The middle segment serves as a guide profile (1) and is made to overlap, whilst the outer segments are variation profiles. Since the guide profile (1) is always present unchanged in all the keys and locks of a master-key system, the overlap of the profile elements is also present in each lock. The overlap in the middle part of the key channel (10) ensures especially good protection against probing in the entire system, because the region of attack on the blocking pins (12) is covered. <IMAGE>
