The Omnibombulator

摘自1933年 sunny times 报纸上的一个 puzzle

具体如下：

This unusual instrument is operated by selecting one of the four switch-positions A, B, C, D and turning the power on. The effects are;

Position A - The pratching valve glows and the queech obulates
Position B - The queech obulates and the urfer curls up, but the rumption does not get hot.
Position C - The sneeveling rod turns clockwise, the pratching valve glows and the queech fails to obulate.
Position D - The troglodyser gives off hydrogen but the urfer does not curl up.

Whenever the pratching valve glows the rumption gets hot. Unless the
sneeveling rod turns clockwise, the queech cannot obulate, but if the
sneeveling rod is turning clockwise the troglodyser will not emit hydrogen. If the urfer does not curl up you may be sure that the rumption is not getting hot.

In order to get milk chocolate from the machine you must ensure (a) that the sneeveling rod is turning clockwise AND (b) that, if the troglodyser is emitting hydrogen then the pratching valve is glowing, but that if the troglodyser is not emitting hydrogen, the queech is not obulating.
Which switch position would you select?

If, tiring of chocolate, you wish to receive the Third Programme you must take care (a) that the rumption does not get hot AND (b) either the urfer doesn抰 curl and the queech doesn抰 obulate OR that the pratching valve glows and the troglodyser fails to emit hydrogen,

I recently bought an old book published in 1933, and in it was a newspaper clipping from the Sunday Times showing 態rain Teaser no 44�. Entries had to be in by Friday January 26, but no year is given - any guesses as to the year?. I have shown the puzzle below.

I have my own ideas as to the answers, but if anyone else would like to have a go then please send me an e-mail with your answers and reasoning.

Which switch position would you select?
