Filed: 1983-06-29
Granted: 1986-12-11
Abstract: The present invention is with respect to a reflectance measuring head that is designed for stopping the production of false readings by regular (as opposed to diffuse) reflection and shiny parts of the sample without using normal shine traps or diaphragms. False readings as produced by regular reflection, by surface grain or structure and by inhomogeneity of the surface of the sample are furthermore put an end to by having a number of transmitters placed at an equal distance from one receiver or having a number of receivers placed at an equal distance from a transmitter. A more specially useful effect is produced if a number of transmitters and a number of receivers are placed alternately in the form of a matrix.

Inventor: NONNENMANN MANFRED DR
IPC: B01D53/86
Filed: 1985-12-04
Granted: 1989-08-03
Abstract: A carrier matrix for a catalytic reactor for the purification of the exhaust gas of internal combustion engines, comprising a flat foil and a corrugated foil arranged in alternating layers. Exhaust gas flows through the ducts formed by the corrugations of the corrugated foil and the flat foil surface. The corrugations have a plurality of segments fluidly connected behind one another in flow direction, but are transversely staggered with respect to flow direction. This staggered arrangement increases the turbulence of the gas flowing through the ducts, thereby increasing the effectiveness of the matrix. The matrix can be manufactured in a simple manner yet permits a good utilization of the catalyst materials coated on the foils.

Filed: 1985-10-31
Granted: 1992-07-16
Abstract: A single-chip microprogram sequence controller which can be selectively operated in either an interrupt mode or a trapped mode. In the interrupt mode, the microprogram sequencer allows the currently-executing microinstruction to finish execution before beginning the interrupt routine which services the asynchronous event which requested the interruption of the presently-executing microinstruction stream. In the trap mode, the sequencer aborts the currently-executing microinstruction to avoid an irreversible error which would result if the microinstruction were to finish execution before beginning the routine which services the event which requested trapping of the presently-executing microinstruction. Depending on the mode selected, the sequencer stores the address on a last-in, first-out stack of either the next-following microinstruction or the currently-executing microinstruction for return to the proper point in the microinstruction stream upon completion of the routine which requested the interrupt or the trap.
