Many anomalies existed before 1939 in the State employment of professional men, and these have been aggravated by the number and diversity of war-time appointments. The Institution of Professional Civil Servants, a body representing about 30,000 professional, scientific, and technical employees of the State, comprising more than 500 grades, has drawn up its proposals for the Post-war reconstruction of the technical
Civil Service, which, if accepted by the Government, would reduce the number of classes of such employees to three, with two grades in both the higher classes.
Mr. B. Rhodes: Mr. Longbottom has done less than justice to large diameter strand, by which I mean 28 mm (1 1/8 in) diameter strand. I know it is not used a lot, but this is really because of lack of effort on the part of the manufacturers and the system suppliers. 28 mm diameter strand has certain basic drawbacks, namely:
1. The shape of the load/extension curve
2. Relaxation losses at 6 per cent
3. Lower grip efficiencies
4. The tendency to fly open when cut
5. The 'banana' effect at the ends
