Abstract: A cooling assembly for a motor vehicle, the cooling assembly having a primary heat exchanger comprising a pair of primary collector boxes, the primary collector boxes with primary header plates, the primary header plates being of essentially rectangular shape; a plurality of primary tubes stacked between the primary header plates; a secondary heat exchanger comprising a pair of secondary collector boxes with secondary header plates being of essentially rectangular shape; a plurality of secondary tubes stacked between the secondary collector boxes. The primary heat exchanger and the secondary heat exchanger are arranged in parallel, perpendicularly to each other so that the secondary header plates of the secondary heat exchanger at least partially overlap the stack of the primary tubes of the primary heat exchanger.

Abstract: The invention relates to the process for the preparation of iron(III) chelates of N,N?-di(2-hydroxybenzyl)ethylenediamine-N,N?-diacetic acid and its derivatives of the formula (I) wherein both R substituents have the same meaning and represent H, C1-C4 alkyl, CH2OH, SO3M or COOM, and M is a sodium, potassium or ammonium cation, wherein the aqueous solution of a corresponding chelating agent is contacted with metallic iron by the circulation of said aqueous solution through the bed of pieces of metallic iron in a flow reactor while simultaneously blowing air or oxygen through the aqueous solution of the chelating agent in the flow reactor, optionally in the presence of a hydrogen peroxide solution. Chelates of the formula (I) are useful as the components of plant fertilizers.

Abstract: The invention relates to a process for the preparation of N,N?-bis(2-hydroxybenzyl)-ethylenediamine-N,N?-diacetic acid and its derivatives of general formula (I), wherein both R have the same meaning and are selected from H, C1-C4alkyl, CH2OH, SO3M, and COOM; and all M have the same meaning and represent hydrogen atom, Na, K or NH4; which comprises reductive amination of glyoxylic acid with a salan compound of general formula (II), in the presence of an amine proton acceptor. The compounds of formula (I) can be used as chelating agents for micronutrients in fertilizer preparations for plants.

Abstract: Apparatus for making shells from thermosetting liquid compounds in which at a first station, a travelling and heated permanent metal mould becomes filled with a thermosetting liquid compound. The mould is then moved to a second station where it is held until a shell wall of desired thickness is obtained. Thereafter, the mould is transferred to a further station where excess thermosetting compound is recovered and dispensed to an accumulative mixer to be used again. Subsequently, the metal mould is passed to a final station where it is opened and the ready shell removed. The apparatus comprises said and liquid constituent containers, a sand feeder and two mixers, namely, a basic mixer and an accumulative mixer. The apparatus is provided with a unit for proportioning the liquid constituents and a delivery unit to force the compound into the mould.
