Abstract: 1,232,361. Fluidic elements. WERKZEUGMASCHINENKOMBINAT "FRITZ HECKERT" KARL - MARX - STADT. 13 March, 1969, No. 13337/69. Heading G4P. Planar turbulence amplifiers are arranged in a stack, adjacent amplifiers being separated by venting or masking plates. In the case of venting plates, each plate 2 has channels 8 with rough reflection-inhibiting surfaces facing the free jet regions of the adjacent amplifiers. If masking plates are used these mask about 50% of the free jet region, Fig. 4 (not shown). The presence of the venting or masking plates reduces interference between the amplifiers, and prevents the jet from being reflected back in to the free jet region.

Flexible polyurethane foams are prepared by reacting an unrefined primary diamine phosgenation product having an amine number of 87 to 168 with a polymeric polyol in the presence of a primary diamine as a chain extender, a blowing agent and a catalyst for the waterisocyanate and/or polyol-isocyanate reaction. The foams may be made by the prepolymer, semi-prepolymer or one shot techniques, if desired also in the presence of a foam stabilizer. The unrefined primary diamine phosgenation product is suitably prepared from a mixture of toluene-2,4- and 2,6-diamines and may be mixed with a proportion of a relatively pure tolylene diisocyanate such as distilled tolylene diisocyanates or a mixture of tolylene 2,4- and 2,6-diisocyanates, or with a tar component obtained as a by-product in the phosgenation process and having an NCO content of 20 to 30%. Suitably the polymeric polyol is a polyalkylene ether diol or triol, which are preferably tipped with ethylene oxide. The primary diamine chain extender is preferably an arylene diamine such as o-toluene diamine, m-phenylene diamine, 2,5-dichlorophenylene- 1 4-diamine and especially diamines having two phenyl radicals each substituted with an amino group, particularly the crude reaction products of aniline and 2-chloroaniline with formaldehyde which reaction products contain 3-chloro-4,41-diaminodiphenylmethane. Water is the preferred blowing agent but methylene chloride and fluorocarbons may be used. Conventional tertiary amine and organo-tin catalysts may be used. The reaction mixture may also contain a non- polymeric polyol.

The method is referred to as "continuum rolling" in the various tabular statement listing examples compared with hot-rolling and lowfinishing-temperature rolling methods. Thus a steel is formed having (a) greater strength and lower Charpy impact transition temperature than steels of the same composition produced by hot rolling and (b) having a lower impact transition temperature than steels of the same composition produced to the same strength by lowfinishing-temperature rolling. The rolling sequence may include one or more reduction passes above Ar 3 , a reduction pass being defined as either a single pass in which the reduction is at least 15% or more than one pass producing the same total reduction. The workpiece may be cooled through the Ar 1  point by water sprays or air blasts to prevent complete recrystallization, or this may be allowed if a further reduction pass (6), Fig. 1 (not shown), follows before the Ar 1  temperature is reached. Seven steel compositions are listed in Table 3 (not shown) and a further example is given in the description; values of impact transition temperature for "continuum rolling" range between -85‹ and -285‹ F., yield strength being not less than 65,000 p.s.i.
