Abstract: A flow converter for an air flow rate meter, especially for an intake conduit of an internal combustion engine, includes a plastic flow rectifier for converting an aspirated air mass into a laminar air flow moving in a given flow direction. The flow rectifier includes a honeycomb body and a ring integral with the honeycomb body. The honeycomb body has a surface disposed at right angles to the given flow direction and the ring protrudes out of the surface. A grid is permanently secured to the flow rectifier for generating microscopic eddies in the laminar air flow. A method for producing a flow converter for an air flow rate meter includes integrally injection molding a thermoplastic flow rectifier for converting an aspirated air mass into a laminar air flow moving in a given flow direction. The flow rectifier includes a honeycomb body having a surface disposed at right angles to the given flow direction and a ring protruding out of the surface.

Abstract: A timing arrangement incorporates a timing disk having absolute marks arranged about a circle and serving for the identification of the angular position of the shaft of an internal combustion engine. The marks include a code track havig code marks and absolute marks, each absolute marks being preceded by a code element comprising a number of code marks. Each absolute mark is identified by a code section preceding and consisting of two or more code elements.
