A FEW brief words on the Total Quality Control concept where in embraced the whole brief of the Quality Engineer — the field of design (conformance with constructor's requirements), manufacture (conformance with specifications) and reliability (conformance with users' requirements). Ideally the Quality Engineer will liaise with both Sales and Design engineers to achieve complete drawing board conformance with customer requirements at the design stage and it is at this stage where, of course, a designer needs to know exactly what is wanted of him. More important, he needs room for manoeuvre, for alternative proposals. As far as concerns aircraft, it is not so long since the tyre designers used to be faced with the appalling difficulty of being presented with a hole of very limited dimensions in each wheel bay into which he had to fit a tyre or tyres come what may. Apart from the limited dimensions of the hole, its dimensions were usually by this time inviolable. If we were lucky we would have some idea of the aircraft take‐off and landing weights and speeds, essential parameters with which the tyre designer commences his calculations.

The Minister of Aviation Supply, Mr F. G. Corfield, with the agreement of the Prime Minister, has appointed Mr J. A. Hamilton, M.B.E., to be a Deputy Secretary in the Ministry of Aviation Supply. He succeeds Mr F. J. Doggett, C.B., who retired on 7 January 1971. Mr Hamilton was previously Director‐General Concorde. Mr T. P. Jones, previously an Assistant Secretary in the Concorde Division of the Ministry of Aviation Supply, has been appointed Under Secretary and is to succeed Mr Hamilton as Director‐General of the Concorde project.

On the twenty‐sixth of August, at the early age of fifty‐nine, WILLIAM HENRY CORFIELD passed away.

The question has been recently raised as to how far the operation of the Sale of Food and Drugs Acts of 1875, 1879, and 1899, and the Margarine Act, 1887, is affected by the Act 29 Charles II., cap. 7, “for the better observation of the Lord's Day, commonly called Sunday.” At first sight it would seem a palpable absurdity to suppose that a man could escape the penalties of one offence because he has committed another breach of the law at the same time, and in this respect law and common‐sense are, broadly speaking, in agreement; yet there are one or two cases in which at least some show of argument can be brought forward in favour of the opposite contention.

That the introduction of the Control system should have given rise to a considerable amount of criticism, both appreciative and adverse, was naturally to be expected. The appreciative remarks which have appeared in the press, and those also which have been privately communicated to the directors, indicate that the subject has been intelligently considered, and in some cases carefully investigated and studied. The opinions given are worth having on account of the position and influence of hose who have given them, and on account of the obvious freedom from bias which has characterised them. This is so far satisfactory, and goes to show that the success which has attended the working of the Control system abroad may well be expected to attend it in this country as soon as it is sufficiently well known to be appreciated by the manufacturers and vendors of good and genuine products, and by the general public, whose best interests it cannot but serve.

Some misconception appears to have arisen in respect to the meaning of Section 11 of the Food and Drugs Act, 1899, owing, doubtless, to the faulty punctuation of certain copies of the Act, and the Sanitary Record has done good service by calling attention to the matter. The trouble has clearly been caused by the insertion of a comma after the word “condensed” in certain copies of the Act, and the non‐insertion of this comma in other copies. The words of the section, as printed by the Sanitary Record, are as follows: “Every tin or other receptacle containing condensed, separated or skimmed milk must bear a label clearly visible to the purchaser on which the words ‘Machine‐skimmed Milk,’ or ‘Skimmed Milk,’ as the case may require, are printed in large and legible type.”

There are very few individuals who have studied the question of weights and measures who do not most strongly favour the decimal system. The disadvantages of the weights and measures at present in use in the United Kingdom are indeed manifold. At the very commencement of life the schoolboy is expected to commit to memory the conglomerate mass of facts and figures which he usually refers to as “Tables,” and in this way the greater part of twelve months is absorbed. And when he has so learned them, what is the result? Immediately he leaves school he forgets the whole of them, unless he happens to enter a business‐house in which some of them are still in use; and it ought to be plain that the case would be very different were all our weights and measures divided or multiplied decimally. Instead of wasting twelve months, the pupil would almost be taught to understand the decimal system in two or three lessons, and so simple is the explanation that he would never be likely to forget it. There is perhaps no more interesting, ingenious and useful example of the decimal system than that in use in France. There the standard of length is the metre, the standard of capacity the cubic decimetre or the litre, while one cubic centimetre of distilled water weighs exactly one gramme, the standard of weight. Thus the measures of length, capacity and weight are most closely and usefully related. In the present English system there is absolutely no relationship between these weights and measures. Frequently a weight or measure bearing the same name has a different value for different bodies. Take, for instance, the stone; for dead meat its value is 8 pounds, for live meat 14 pounds; and other instances will occur to anyone who happens to remember his “Tables.” How much simpler for the business man to reckon in multiples of ten for everything than in the present confusing jumble. Mental arithmetic in matters of buying and selling would become much easier, undoubtedly more accurate, and the possibility of petty fraud be far more remote, because even the most dense could rapidly calculate by using the decimal system.

What proof have the public, independent of the assertions of the makers, that all the firms whose products are sold indifferently by the shopkeepers use only the best materials; or, indeed, that a large number of the articles sold are not mixtures more or less objectionable or fraudulent ? This, in effect, is the question put by a writer in a West of England newspaper, and it might be used as a text upon which to write a lengthy homily on the adulteration question and on the astonishing gullibility of the public. As a matter of fact the only evidence of the character and quality of food and other products, in regard to which there is no independent guarantee, is that which is afforded by the standing of the makers, and to some extent of the firms which offer them for sale. And this evidence cannot, under any circumstances, be looked upon as constituting proof. The startling allegations so commonly put forward by advertisers with respect to their wares, while they may be ineffective in so far as thinking people are concerned, must nevertheless be found pecuniarily advantageous since the expense involved in placing them under the eyes of the public would otherwise hardly be incurred. Many of these advertised allegations are, of course, entirely unjustifiable, or are incapable of proof. It may be hoped that the lavish manner in which they are set out, and their very extravagance, may, in time, result in producing a general effect not contemplated by the advertisers. In the meantime it cannot be too often pointed out that proof, such as that which is required for the satisfaction of the retailer and for the protection of the public, can only be obtained by the exercise of an independent control, and, in certain cases, by the maintenance of efficient independent inspection in addition, so that a guarantee of a character entirely different to that which may be offered, even by a firm of the highest eminence, may be supplied.

Mr. LEVENSTEIN, the President of the Society of Chemical Industry, in his address delivered at Liverpool recently, dealt very fully with the question of the commercial position of Great Britain as compared with other countries, more especially Germany, and emphasised the fact that if this country is to compete successfully with her contemporaries she must, to use the words of the Prince of Wales at the Gúildhall, “wake up.” After reviewing the chief factors making for Germany's advance in industry and commerce Mr. LEVENSTEIN says: “How are we to defend ourselves? Shall we rest content as we are or bestir ourselves and awake to the irresistible fact that continued apathy and indifference mean ruin to our national position?” This is strong language but not stronger than the occasion demands, for the statistics by which these observations are backed clearly indicate a marked decadence in the national prosperity notwithstanding the years of apparent “record” trade, which, however, cannot be regarded so favourably when subjected to detailed analysis and comparison. Mr. LEVENSTEIN'S suggestions to meet this situation are as follows: (1) The appointment of a competent and expert Minister of Commerce. (2) The nationalisation and extension of our canals and waterways. (3) A measure for greatly extending and improving our secondary education. (4) A sensible reform of our patent laws.

The librarian and researcher have to be able to uncover specific articles in their areas of interest. This Bibliography is designed to help. Volume IV, like Volume III, contains features to help the reader to retrieve relevant literature from MCB University Press' considerable output. Each entry within has been indexed according to author(s) and the Fifth Edition of the SCIMP/SCAMP Thesaurus. The latter thus provides a full subject index to facilitate rapid retrieval. Each article or book is assigned its own unique number and this is used in both the subject and author index. This Volume indexes 29 journals indicating the depth, coverage and expansion of MCB's portfolio.
