Abstract: A heat accumulator for use in a motor vehicle having a heat accumulator container which can be integrated into the motor oil circuit, through which motor oil flows when the motor is running, and which is disconnected from the circuit when the motor is switched off. The oil pan of the motor, in particular the lower part of the oil pan, is provided as the heat accumulator container, and the oil pan is provided with heat-insulating container walls. Also, an element for increasing the heat capacity of the heat accumulator is provided.

Abstract: A heat exchanger, particularly for a motor vehicle, having a plate in which tubes are arranged, whereby at least one turbulator is arranged in the tubes, whereby the turbulator, viewed in a longitudinal extension, has a first turbulator end and a second turbulator end, whereby a turbulator area is arranged therebetween, whereby the turbulator has a reinforced wall at least one turbulator end, whereby the reinforced wall of the turbulator, at the at least one turbulator end is thicker than the wall of the turbulator area. The invention relates further to a production method for a heat exchanger.

Abstract: The invention relates to an arrangement of a charge air cooler in an intake pipe, wherein the charge air cooler has a cooler block through which charge air can flow and the charge air cooler can be inserted into the intake pipe through a first opening in said intake pipe, wherein the cooler block has at least one first outer wall and at least one second outer wall, which outer walls run along the main direction of extent of the cooler block and bound the region of the cooler block through which charge air can flow, wherein the intake pipe surrounds, on three sides, that part of the charge air cooler which can be inserted, so that charge air can flow through the cooler block of the charge air cooler within the intake pipe.

Abstract: Arrangement of an intercooler in an intake pipe, wherein the intercooler has a cooler block through which charge air can flow and a first opening through the intake pipe, through which the intercooler can be inserted into the intake pipe, wherein the intake pipe has a second opening, which is arranged substantially opposite the first opening and can be closed by means of a housing part.

Abstract: This application provides, inter alia, processes for producing an integral bond between a high-grade steel component and an aluminum or aluminum alloy component. In an exemplary embodiment, the process comprises coating the high-grade steel first with a nickel layer and second an aluminum layer, arranging the coated high-grade steel and the aluminum or aluminum alloy components in relation to one another in such a manner that partial regions of the first and of the second component are arranged parallel to one another and either bear areally against one another or are arranged with a gap of 0 mm to 5 mm in relation to one another, and integrally bonding the coated high-grade steel component to the aluminum or aluminum alloy component by using a cold metal transfer process.

Abstract: The invention relates to a method and a device for quantitative and qualitative on-line differentiation of biotic and abiotic particles. The methods and devices are used to ensure quality and to monitor production as well as in analysis procedures for particular contamination's of gaseous media. The methods and devices are chiefly used in pharmacology, food technology, medicine, biotechnology and health care and in controlling maximum admissible concentration values. According to the inventive method, the gas sample to be measured is briefly heated at very high temperatures in a heating chamber (3). Dimensional distribution of particle contamination is determined before and after heating by means of diffuse light sensors (1, 2). Dimensional changes of biotic panicles caused by heating make it possible to determine their proportion in total particle load of the gas sample and their composition.
