Abstract: 913,800. Rocket motors. UNITED AIRCRAFT CORPORATION. April 13, 1961 [April 13, 1960], No. 13374/61. Class 110 (3). [Also in Group XXXIII] The Figure is a cross-section through a nozzle mounted on the part-spherical end 22 of a rocket combustion chamber 20. A convergent section 6 has a longitudinal axis 14, and a divergent section 10 has a longitudinal axis 16, the axes intersecting at a point located upstream of the throat 8, preferably by 5-10% of the nozzle length. The bending of the gas flow within the nozzle creates a shock-wave which causes thickening of the boundary layer in the throat, or flow separation. In either case, erosion of the throat by the gas stream is reduced. The whole nozzle is rotatable for control purposes. In a modification, Fig. 3 (not shown), only the divergent portion is rotatable, and the axes of the convergent and divergent portions intersect at a point located downstream of the throat, preferably by 5-10% of the nozzle length.

Abstract: <PICT:0438271/IV/1> Bis-b -dichloralkyl ethers are obtained by the action of chlorine and olefines on alkylene chlorhydrins or substances producing the same, in which reaction chloralkylhypochlorites are first formed and are then acted on with olefines.  The starting materials may also be an alkylene oxide, chlorine and an olefine; water, chlorine and an olefine; or water, an alkylene oxide, chlorine and an olefine.  According to examples: (1) ethylene and chlorine are bubbled through ethylene chlorhydrin, excess of water added and the products distilled, to give dichlorethyl ether together with ethylene dichloride; (2) propylene and chlorine are bubbled through ethylene chlorhydrin to give bis-b -chlor-ethylisopropylether; (3) chlorine and ethylene are bubbled through ethylene chlorhydrin with the addition of ethylene oxide after some time, in such proportion as to allow the mixture to remain slightly acid; (4) a reaction mixture containing ethylene chlorhydrin, dichlorethylether, ethylene dichloride and water is treated with chlorine and excess of ethylene; the excess ethylene and hydrochloric acid formed passes off, water is added continuously and no further addition of chlorhydrin is necessary, to produce a good yield of dichlorethyl ether; (5) in the preferred apparatus shown, ethylene is introduced by a diffuser 11 into water in a reaction tower 10, the liquid contents of which are continuously circulated by pump 15 through a cooler 16, and chlorine is introduced by a diffuser 18; gaseous products are removed by a line 20 through a condenser 21, connected to a compressor 24, by which the issuing gases can be re-circulated if desired; fresh ethylene may be added through the line 25 and ethylene oxide by a line 26, while excess gases may be removed by a blow-off line 29 from tower 22; the crude condensate is drawn off by line 27, and the products separated by adding water, and fractionally distilling the lower layer; (6) dichlorisopropylether is obtained by the action of propylene, propylene oxide and chlorine on water as in the previous example.  Dichlorides and other compounds are formed as by-products.  Temperatures employed may be about 30 DEG C.
