Abstract: A motor vehicle housing, for cooling automotive type accessory components, with a receptacle chamber designed for the installation of pre-determined components, and with a cooling chamber sealed with respect to the receptacle chamber and adjacent to it, which cooling chamber is connected with an inlet for coolant and with an outlet for the coolant, has been improved so that no coolant can get into the receptacle chamber, and the receptacle chamber has zones in which different degrees of cooling can take place. For this purpose the cooling chamber is provided with an integrated flow guide for the coolant which, in a first segment adjacent to the inlet, has an expanded portion which provides for a distribution of the coolant over a large surface, and in a second segment runs so that, in relation to a predetermined total length of the flow guide, the heat exchange surface of the flow guide assumes a maximum opposite the contact surface in this segment between the cooling chamber and the receptacle chamber.

Abstract: An anti-roll vehicular suspension system and a hydraulic rotary actuator system in an anti-roll vehicular suspension system with a hydraulic rotary actuator in a two-part stabilizer apparatus, having a first stabilizer part, which is non-rotationally connected to a rotary actuator shaft, and a second stabilizer part, which is connected non-rotationally to a rotary actuator housing, whereby a plug-in connection with a mounting bracket serves as a connection between the stabilizer part and the rotary actuator.

Abstract: A portable instrument for testing air or other gaseous bodies for foreign bstances such as germs and bacteria employs a cultural substrate against which a surrounding portion of the atmosphere is urged by rotating impeller blades.
