Patent DE-4205647-A1 (DE)
Inventor: BINA WENZEL DIPL ING
IPC: C21D1/78
Filed: 1992-02-25
Abstract: The invention relates to a process for the thermochemical-heat treatment of case-hardened steels in which an edge region of a workpiece, especially tappets, roller bearing components, drive and clutch components, can be enriched with carbon and nitrogen and subsequently subjected to martensitic hardening. In the process of the invention, carbon nitriding (1) is performed at temperature of 780 to 1050  DEG C with the case-hardening and nitriding of the edge region with 0.4 to 0.9 wt % carbon and 0.1 to 0.8 wt % nitrogen for a period of 1 to 4 hours, carbo-nitriding is followed by quenching (2) of a temperature well below the initial martensite point of the edge region, followed in turn by an annealing process (3) at a temperature of 20 to 40  DEG C above a nitrocarburising temperature at a heating rate of 10 to 30  DEG C per minute over a period of 1 to 2 hours and cooling (4) to room temperature, again followed by the material-removing shaping of the workpiece, after which finally nitrocarburing (6) takes place at a temperature of 500 to 600  DEG C for 60 to 150 minutes and cooling (7) to room temperature. The process of the invention gives the material high wear resistance and carrying capacity even under the heaviest tribologic stress.

Title: Building block for toy or model system
Inventor: KROCZEK MANFRED DIPL ING
IPC: A63H33/06
Filed: 1993-03-03
Abstract: Toys and model systems which are based on the principle of building a three-dimensional structure from a number of parts of identical design are often complex in their form. The known solutions in this field have been produced from plastics. Production is cost-effective only if large numbers of units are made.   The part developed is simple in shape and hence can be produced cost-effectively even in very small numbers. Various materials can be used: wood, plastics, metal, aluminium. The rigidity values of the assembled structures are very good, owing to positive fitting and a great deal of frictional fitting. The element is particularly well suited to the development and encouragement of three-dimensional thinking and the sense of combination and feeling in children and as an interesting mental exercise for adults. The structures which can be built range from very simple to quite complex.
