Abstract: The invention comprises reactive dyes of formula <FORM:1000801/C4-C5/1> wherein F is an organic dye radical, Q is an -SO2-NR1-, -NR1-SO2-, -CO-NR1- or -NR1-CO- bridge member, R1 being hydrogen or C1-C5 alkyl, A is a six-membered carbocyclic ring, X is a hydrogen or chlorine atom or a methyl group, Y1 is a chlorine atom or an alkylsulphonyl or arylsulphonyl radical, Z is -O-, -S- or =N-CH3, m is 1 or 2 and n is 1, 2 or 3.  The dyes may be prepared by condensing a dye or a diazo or coupling component containing an amino or amide group with a compound of formula <FORM:1000801/C4-C5/2> wherein W is a carboxylic or sulphonic acid halide group and if an azo dye component is used forming the dye by the usual coupling reaction.  Conversely dyestuff acid halides may be condensed with compounds of the above formula wherein W is an amino group.  The dyes may be used to colour amide or hydroxyl group-containing fibres by the usual reactive dye processes.

[Class 114] The blade of a screw propeller is formed so that intercepts of planes perpendicular to the propeller axis and the working face of the blade are curves of equal or nearly equal radius and concave in the direction of rotation of the propeller, the intercepts of axial planes of the working face being practically straight lines. For determining the outline of the blade, points 13 and 150 on the hub indicate the blade width at the root and the arc 13-150 is bisected at 80 and the radial line through 80 terminates at a point 9 such that the length 9-100 is equal to half of the radius of the propeller. Arcs are then struck with centres 150 and 9 with a radius equal to that of the propeller which cross at 610 which is the centre about which the trailing edge of the blade is described with a radius substantially equal to that of the propeller. The leading edge 7 is described with the same radius about a centre on the line 70 which centre is determinated by the desired width of the blade at the inner and outer portions. The tip portion 4 is an arc about a point 10 so chosen that it is tangential to the edges 6 and 7 and also to an arc described about the centre of the propeller with a radius equal to that of the propeller. The working face of the blade is straight along radial lines 11, 17 and 18 and this generatrix is so disposed that planes perpendicular to the propeller axis cut it to produce curves of radius substantially equal to that of the propeller and concave in a direction of rotation thereof.
