Abstract: The present disclosure generally relates to a particulate composition that includes a particulate source of stannous, alumina, and a drying aid. The disclosure further relates to a method for improving the flowability of particulate stannous by admixing the alumina and the drying aid with it thereby giving improved flow properties to the stannous chloride.

Abstract: The present invention relates to a method for detecting temporally varying thermomechanical stresses and/or stress gradients over the wall thickness of metal bodies, in particular pipelines. In the method, the temperature on the outer surface of the body is measured in order to determine a temperature progression and stress progression therefrom. In addition, electromagnetic ultrasonic transducers are used at at least one measuring point on the outer surface in order to determine the progression of the stresses and/or stress gradients over time over the wall thickness of the body in conjunction with the result of the temperature measurement. The method allows the fatigue monitoring of pipelines even in the event of rapid stress changes.

Abstract: This invention relates to configuration of at least two exhaust gas turbochargers on an internal combustion engine with a plurality of cylinders, in particular in a motor vehicle, in which the two turbine housings are connected to the exhaust gas system of the internal combustion engine and are immediately adjacent to each other and one turbine is always connected to one compressor by means of a drive shaft, the drive shafts being rotatably mounted in corresponding bearing housings. In order to prepare a design which is advantageous from the viewpoint of structure and production technology, it is proposed that the turbine housings are oriented such that the drive shafts be positioned at least approximately in alignment with each other and that the bearing housings be connected to the turbine housings on both sides.

Abstract: The invention relates to a method for treating metallic surfaces consisting of zinc, magnesium or aluminium or of the alloys of zinc, magnesium or aluminium, to which lacquer, coatings of plastic material, paint, sealants or adhesives are applied after treatment. The treatment of the metallic surfaces takes place at between 10° C. and 100° C. by immersion, spraying or rolling with an aqueous solution. The solution has a pH of between 2 and 13 and contains one or more compounds of the type XYZ at a concentration of between 10−5 and 1 mol/l. Y is an organic group containing between 2 and 50 C atoms and has a straight-chain structure. X is a COOH, HSO3, HSO4, (OH)2PO, (OH)2PO2, (OH)(OR′)PO or (OH)(OR′)PO2 group. Z is a OH, SH, NH2, NHR′, CN, CH═CH2, OCN, epoxy, CH2═CR″—COO, acrylamide, COOH, (OH)2PO, (OH)2PO2, (OH)(OR′)PO or (OH)(OR′)PO2 group. R′ is an alkyl group with between 1 and 4 C atoms.

Abstract: The invention concerns a control arrangement for an automatic electrohydraulically controlled transmission. In order to reduce expenditure on parts and assembly, the hydraulic control system and electronic control system are mounted directly adjacent each other and plug-in connections are provided between the solenoid valves of the hydraulic control system and the electronic control system. The hydraulic control system (20) substantially comprises two duct panels (28,30) in which control ducts, piston slides and solenoid valves (not shown) are disposed for controlling the conical plates and couplings of the transmission. The pressurized hydraulic fluid is fed directly into these duct panels from the pump (29). The electronic control system (22) has a single central connection (36) which is secured in the transmission housing cover (42) by an annular seal. Rotational speed sensors for the transmission shafts and temperature and pressure sensors are integrated into the control unit.

Abstract: A composition of inorganic powders comprises inorganic powder, dispersant and binder. The dispersant and/or binder used is a block copolymer of the units methacrylic acid and alkyl methacrylate in which the alkyl radical can comprise from 1 to 8 carbon atoms. The individual blocks of alkyl methacrylate possess an average molecular weight of at least 4000 and the total block copolymer has an average molecular weight of up to 150,000, in each case expressed as number average (M.sub.n).
