Abstract
The reasons why a coating is selected as suitable for use on a pipeline would normally depend upon two major factors. Firstly, the performance of the available coatings has to be evaluated according to their technical characteristics. Secondly, price, which is more often influenced by application techniques rather than actual material cost.

Abstract
IN the earliest stages of the development of the aeroplane the speed range obtainable was small, flight occurred only at fairly high lift coefficients, and induced drag was the predominant component of total resistance, hence successful flight depended on the achievement rather of minimum weight, minimum wing loading and maximum engine power than on the achievement of minimum possible parasite resistance.

Abstract
THE subject of air‐cooled engine cowling is one in which we have taken a special interest ever since the inception of AIRCRAFT ENGINEERING. In our first issue, in March 1929, we published the now famous Technical Note No. 301, which first gave the results of wind tunnel experiments with the then new N.A.C.A. cowling, and in the following month we published a full summary of Report No. 314, which developed the subject. Following with dramatic rapidity came rumours of the Townend Ring, the tests with which were first revealed to the public at the annual “Inspection” of the N.P.L. on June 18th, 1929, some of which were published in the issue of AIRCRAFT ENGINEERING for July of that year. Mr. Townend read his paper on his invention to the Royal Aeronautical Society on March 6th, 1930, and this appeared in full in these pages the following month.

Abstract
IT is well known that the drag of an air‐cooled engine can be much reduced by the addition of a suitable form of cowling. The present tests were undertaken to investigate the cowling of an air‐cooled radial engine and in particular to develop a suitable “helmet” cowling for this type of engine. Certain other forms of cowling have also been tested. From the results obtained estimates have been made of the probable improvement in performance resulting from the various types of cowling. Most of the work has been carried out in the No. 17‐ft. tunnel at the Royal Aircraft Establishment; the tests were begun in January, 1929, and have occupied the tunnel at intervals throughout the year.

Abstract
The law of passing‐off concerns itself primarily with the protection of a trader's goodwill — his customer connection. It has proved itself an expansive tort action, being used to combat a diverse variety of commercial dishonesty and unfair competition. In the leading case of ERVEN WARNINK BV v J. TOWNEND & SONS (HULL) (‘the Advocaat case’) [1980] RPC 31, Lord Diplock observed:
As has been said, the commercial “infants' food,” leaving on one side the condensed milk, is almost invariably a powder, and, as such, should conform in composition as nearly as…
Abstract
As has been said, the commercial “infants' food,” leaving on one side the condensed milk, is almost invariably a powder, and, as such, should conform in composition as nearly as possible to a dried human milk. Of course, the preparations are not altogether free from water. From a large number of analyses it appears that the percentage in the great majority of cases varies between 4 and 8, the maximum being 13.9 and the minimum under 1. The average is approximately 6.5 per cent.

Abstract
The controls and queues of the past eleven years have confirmed and consolidated, I think, the conservatism of the British housewife in the matter of buying food. Butter is just national butter. Margarine is what the Minister of Food dictates. Cooking fat is—well, just cooking fat. Those who succumbed to the official boosting of whalemeat, snoek and brisling mostly wish that they had not. Those who were adventurous enough to spend 5s. or 6s. on cans of imported food labelled —apparently with the Minister's approval—with the words “ Sausages in brine ”, discovered that they had about 11 ounces of sausages in a pint or more of salt water. Could anything be more destructive of willingness to try something new? I am led to make these banal observations by what is happening in this country in the matter of quick‐frosted foods. There is now a National Association of wholesale distributors of these products, which is resolved to try to overcome, by suitable propaganda, the sales‐resistance of the British housewife; and, as a mere looker‐on, I wish them well. Close to my house, in a London suburb, I notice that quick‐frosted fruits and vegetables are on sale at the shops of a dairy firm, a grocer, a provision dealer and a fruiterer (all these are multiple shops), and also at a health food store. Some of the largest firms, including the Unilever mammoth, are now in this business, which is operated on a colossal scale in the United States. It would be boring to give many figures, but I learn that on January 1st, 1949, the stocks of these frozen foods in American warehouses, according to the U.S. Department of Agriculture, were as under: —
