Patent DE-4105469-A1 (DE)
Inventor: BRUECK ROLF DIPL ING
IPC: F01N3/28
Filed: 1991-02-21
Abstract: A honeycombed body (1) with an axis (2) is composed of at least one pile (3, 31, 32) of at least one sheet metal (4;5) and contains defined channels (6) through which a fluid can flow through the honeycombed body (1) in a direction essentially parallel to the axis (2). The pile (3, 31, 32) has at least one section (7, 71, 72) wound around the axis (2) upon which rests at least an intermediate layer (8, 81, 82) composed of two sheet metals (9; 10) closely superimposed but not directly secured to each other. These sheet metals (9, 10) have corrugations (11) that extend as an helical line around the axis (2) and that define a sense of helix proper to the honeycombed body (1). This sense of helix allows the honeycombed body (1) to deform under thermal stress by describing a helical movement along the axis (2), without damaging its inner structure. The thermal stability under load of the honeycombed body (1) is essentially only determined by the high temperature resistance of the sheet metal used (4; 5; 9; 10).

Patent DE-4107668-A1 (DE)
Inventor: STIPAK KARL
IPC: G08B29/16
Filed: 1991-03-09
Abstract: A security switching device (1) is used for monitoring two sensors (2,2') which check the same function in a system. The two sensors (2,2') are connected to associated inputs (4,4') of the security switching device (1). The security switching device (1) contains two timing circuits (9,9'), each of which is allocated to one input (4,4'). The timing circuits (9,9') only supply an output signal when the signals at the inputs (4,4') of the security switching device (1) simultaneously rise to the operating value within the time windows implemented. If this is the case, a feedback circuit (11) becomes effective which initially suppresses the effect of the time windows until the signal returns from the value in the operating state to the rest state at one of the inputs (4,4'). <IMAGE>
