Abstract: An optoelectronic component for data transmission with infrared radiation is described. This component integrates in a single housing an infrared transmitter, an infrared receiver and an integrated circuit for signal conditioning. owing to a particular design of the connecting legs, all of which emerge from the housing at one lateral face and are bent twice through 90° so that they extend in part parallel to this lateral face and in part to the rear side, and owing to additional protrusions on the housing in the form of supporting feet and a bearing shoulder, it is possible to process the IrDA transceiver module both in the top view and in the side view position in surface mounting technology. Assembly is performed with an accuracy that is typical for surface mount devices. No additional mounting aids are needed.

Abstract: In an arrangement for removing water vapor from pressurized gases or gas mixtures, particularly from air, a membrane separating apparatus is provided wherein the gas-vapor stream is separated into a vapor-enriched permeate stream and a vapor-depleted retentate stream and the vapor enriched permeate stream is conducted to a vacuum pumping device for generating at the permeate side of the membrane separating apparatus a vacuum providing for a predetermined trans-membrane pressure ratio.
