Title: Plate-type heat exchanger
IPC: F28F27/02
Filed: 1976-08-02
Abstract: 1532673 Plate-type heat exchanger TRANE CO 2 Aug 1976 [10 Nov 1975] 32131/76 Heading F4S A heat exchanger comprises metallic (e.g. aluminium), plates 12, Fig. 1, which are spaced to form passageways 18, 24 therebetween and have metallic sealing means 14 at their margins. (The heat exchanger can be used for nonadiabatic rectification in which fluids having close boiling points are separated by a repetitive boiling and condensing process by causing gas or vapour to flow upwardly through one passageway in countercurrent flow relationship to a liquid in the same passageway. The process is aided by heat transfer to or from the liquid and vapour by fluid in an adjacent passageway). The spacing of the plates 12 is by corrugated metallic sheets. The arrangement of corrugations of sheets in passageways 18, Fig. 3, differs from that in the alternate passageways 24, Fig. 2. Through each passageway 18 passes a first heat exchange fluid between headers 16 and 20. Through each alternate passageway 24 passes (a) upwardly a gaseous second heat exchange fluid between headers 22 and 26  and (b) downwardly a liquid which takes a  serpentine path between headers 37 and 38 and passes through the gas flow. The corrugated sheets of the heat exchanger are of three kinds, the corrugations 28 being imperforate (Fig. 4, not shown), the corrugations 30 being perforated by round holes (Fig. 5, not shown) and the corrugations 32 being serrated along their lengths and having slits therethrough (Fig. 6, not shown). The serpentine liquid path includes horizontal open spaces 44 and vertical downcomers 42 formed by imperforate corrugated sheets. The gas passes into the liquid in the horizontal parts of the serpentine path via slitted corrugations 32 and perforated corrugations 30. In a modification, Fig. 7 (not shown), the horizontal open spaces 44 and the corrugated perforated metal sheets 30 immediately there below are each replaced by a bar 46, Fig. 9, having slots 54 to allow the upward passage of gas. The various elements of the heat exchanger are braze bonded together.

Title: Improvements in or relating to the production of organic hydroxylamine compounds
Inventor: BIEDERMANN HILDEGARD LIST GEB
IPC: B21B39/18
Filed: 1954-11-05
Abstract: N-Organohydroxylamine is prepared by the oxidation of a primary amine, the amino group of which is linked to a primary or secondary carbon atom, characterized in that the oxidation is carried out using hydrogen peroxide in the presence of a catalyst consisting of a water-soluble salt of molybdic, tungstic or uranic acid and water-soluble salts of aminotriacetic or ethylene diamine-tetra-acetic acid at a temperature at which the primary amine and hydrogen peroxide react together in the molar proportion of 1:1. The reaction temperature is generally less than 12 DEG  C., preferably does not exceed 0 DEG  C., particularly at the beginning of the reaction.  Thus the temperature may be kept sufficiently low so that an amine-hydroperoxide is first produced from the amine, hydrogen peroxide and the water-soluble salt of ethylenediamine-tetra-acetic or aminotriacetic acid, and the hydrperoxide is then contacted with the catalyst.  The process may be carried out in a continuous manner.  In the examples: (1) N-methylhydroxylamine is prepared by the reaction of sodium aminotriacetate, tungstic acid, sodium sulphate, methylamine and hydrogen peroxide in water, and is converted into the hydrochloride salt thereof; (2) n-butylamine, the sodium salt of ethylenediamine-tetra-acetic acid, sodium sulphate and hydrogen peroxide are reacted in water to form n-butylaminehydroperoxide which is then decomposed with a mixture of n-butylamine and tungstic acid in water to form N-n-butylhydroxylamine and is converted into the hydrochloride salt thereof; (3) N-n-propylhydroxylamine is prepared by the reaction of the sodium salt of ethylenediamine - tetra - acetic acid, tungstic acid, sodium sulphate, n-propylamine and hydrogen peroxide in water; (4) N-benzylhydroxylamine is prepared by first reacting benzylamine, the sodium salt of ethylenediamine-tetra-acetic acid, sodium sulphate and hydrogen peroxide in water, and the resulting oil, presumably benzylaminehydroperoxide, is treated with tungstic acid and benzylamine in water; (5) cyclohexylaminehydroperoxide is prepared as in (1), and is treated with cyclohexylamine, tungstic acid and sodium sulphate in water to form N-cyclohexylhydroxylamine.  Specification 779,238 is referred to.

Filed: 1933-11-22
Abstract: Nitric oxide and hydrogen chloride are obtained by reacting nitrosyl chloride and hydrogen or gas mixtures containing these compounds at elevated temperatures below 500 DEG  C.; or at ordinary temperature while allowing absorbable rays to act on the gas mixture.  When the reaction is accelerated by heating, catalysts such as the oxides or chlorides of heavy or light metals, e.g. alumina, pyrolusite, manganous chloride, chromic oxide and silica, or active carbon may be employed.  Active catalysts such as the metals platinum, nickel or the like or easily reducible compounds resulting therein should be excluded.  Examples relate to conducting the reaction, by passing the flowing gas mixture through an empty reaction vessel at 350 DEG  C., at 350 DEG  C. in the presence of alumina or pyrolusite obtained by reacting potassium permanganate with concentrated sulphuric acid, at 200 DEG  C. in the presence of active carbon or at room temperature in a glass vessel exposed to the rays of an ordinary 60 watt lamp. The hydrochloric acid can be removed from the resulting gas mixtures by washing with water and the nitric oxide can be converted with oxygen into nitrogen dioxide for use in the preparation of nitric acid or nitrates.  The Specification as open to inspection under Sect. 91 describes also the employment of absorbable rays at temperatures above ordinary temperatures.  This subject-matter does not appear in the Specification as accepted.
