Patent DE-4307050-A1 (DE)
Title: Tool holding and driving arrangement for hammer drill - involves tool shank with two 180 deg. opposed driving slots and between them two locking slots slightly offset from 180 deg. to give unique tool location
Inventor: NIELSEN MOGENS BJARNE
IPC: B25D17/08
Filed: 1993-03-08
Abstract: The tool or drill (14) has a shank (13) that fits into the bore (15) of the toolholder sleeve (11). Opening onto the end face of the shank (13) are two identical and diametrically opposite driving slots (19) whose load carrying flanks (20) are also diametrically opposite. The driving slots are engaged by two rectangular section keys (21) in the toolholder sleeve. At the bottom of the driving slots is an axial groove (23) into which protrudes a feeler pin (22) forming part of a system for reading coded-tooling information. Between the driving slots are two closed end locking slots (16) which retain the tool in conjunction with locking balls (17). The locking slots are offset from the diametrically opposite position by angle alpha and have cross-sections of different size. ADVANTAGE - Tool has unique angular position, thereby permitting coded tooling information to be carried. Tool remains unweakened.

Title: Cermets containing a ceramic component formed in situ by chemical reaction
Inventor: BREME JUERGEN PROF DR
IPC: C22C1/10
Filed: 1993-03-27
Abstract: Cermets (metal-ceramic composite materials) containing a ceramic component (boride, carbide, nitride or oxide) formed in situ by chemical reaction can be produced by melt or powder metallurgy, if a metal having a high affinity (Nb, Ti, Ta, Zr) is mixed into an alloy containing boron, carbon, nitrogen or oxygen, the metallic constituent of which possesses a lower affinity (e.g. Fe-B, Ni-B, Cu-B, Cr-B, Fe-Ni-B, etc.). On reduction of the corresponding compound or withdrawal of the respective dissolved element, there results precipitation of the desired ceramic compound which possesses the advantage of a chemical bond to the matrix. Compositions which have been found to be particularly favourable are eutectic alloy compositions (e.g. FeB 3.8) which are readily fusable (meltable) and castable because of their low melting point. It is shown that in this way extraordinarily wear-resistant materials can be produced.

Abstract: A microcomputer (M) is electrically connected to the control input of an electronic switching device (S); the load (V), which is connected to the vehicle earth, is connected to the supply, i.e. battery, voltage (UB) via the switching path. A measurement device (ME) for the voltage on the load is connected to the load via a measurement line (ML).
