    摘要： A heat exchanger including a plurality of longitudinal flat tubes stacked together with space between the broad sides of adjacent tubes, and inlet and outlet collecting tanks. The inlet collecting tank distributes a first medium into the tubes, and has a wall extending around the periphery of one end the stack of flat tubes over a selected longitudinal section, the wall having at least one of an inlet and outlet for a second medium distributed in the space between the stacked tubes. The outlet collecting tank receives the first medium from the tubes. Longitudinal internal inserts in the flat tubes are metallically connected to the broad sides of the associated flat tube. At least one row of cutouts is between the longitudinal ends of the internal inserts and in the selected longitudinal section, with the row of cutouts extending substantially across the broad width of the insert.

    摘要： A method is described for the preparation of optically active hydroxamic acids of the general formula wherein R1, R2 and R3 are different and are a cyclic or linear, aliphatic or aromatic, substituted or unsubstituted hydrocarbon radical which can optionally contain heteroatoms, said method being characterized in that a racemate of chiral amides, carboxylic acid esters or carboxylic acids of the general formula wherein R1, R2 and R3 are as defined above and X is —NH2, —OR or —OH, R being any organic radical, is reacted with hydroxylamine, NH2OH, in the presence of an acyltransferase, and the optically active hydroxamic acid (I) formed is then separated from the unconverted enantiomer of general formula (II). The resulting optically active hydroxamic acid can be converted to the corresponding optically active primary amines by a Lossen rearrangement.

    摘要： An economically manufactured heat exchanger is provided and includes a plurality of elongated, straight, flat tubes (16), each formed of two identical halves (78,80) joined to each other in mirror image fashion and each having opposed open ends and all arranged in a stack (18). At least one spacer wall (36) is disposed within each tube and extends generally from end to end thereof to define at least two side-by-side first fluid flow paths within a tube. An elongated housing (10) contains the stack and includes spaced headers (20,22) with each header including a tube slot for the adjacent end of each tube (16) in the stack (18). Spacers (26) in the stack separate adjacent tubes in the stack from one another and the spacers include ribs defining a serpentine flow path for a second fluid. An opening (30) is located in the housing (10) near each end thereof and is in fluid communication with the second fluid flow path (28).
