  • Publication number: 20180074797
    Abstract: The present disclosure relates to a method, system, and medium to transform a data object in a meta model based on a generic type. The system receives a request comprising a data object unrestricted to a predefined format from a client via a REST API. The system categorizes the data object into one of multiple generic types specified in a meta model. The plurality of generic types includes a thing, an information, a relationship, and a handler. Based on the categorized generic types, the system transforms the data object using a handler flow. A handler in the handler flow is defined by the client via the REST API based on receipt of the first request.

  • Publication number: 20080201948
    Abstract: The invention relates to a method of manufacturing a heat exchanger (10) for an air heating apparatus (12) for integration into a housing which guides air. The heat exchanger has a heat exchanger body (14) with a longitudinal axis. According to the invention, the heat exchanger body (14) is at least partially fabricated in a pressure-casting process employing two molded masses (“cores”), with the molded masses being withdrawn from the mold in opposite directions (40, 42) extending along the longitudinal axis.

  • Publication number: 20080017359
    Abstract: The invention relates to a heat exchanger (10) for an air heating apparatus (12) for integration into a housing which guides air. The heat exchanger has a longitudinal axis, wherewith air can be forcibly caused to flow around the heat exchanger in a “main flow direction” which is essentially perpendicular to said longitudinal axis. According to the invention, the heat exchanger has a cross sectional geometry [sic] perpendicular to the “main flow direction” which geometry is flattened with respect to a circular cross sectional geometry (32, 34, 36).

  • Patent number: 6955303
    Abstract: A heating system for heating air, especially for heating the interior of a motor vehicle, with a first heater (10), a second heater (12), and a flow path between the first heater (10) and the second heater (12), there being at least one auxiliary fan (50) with which a flow in the direction from the second heater (12) to the first heater (10) can be produced and a process for influencing the air flows in the heating system are designed to counteract overpressurization. Furthermore, an air heater and a process for detecting backflowing hot air through an air heater use a temperature sensor in an inlet area of the heater for that purpose.
