Solutions of cobalt nitrate sealed in vials were circulated to all clinical chemistry laboratories in the United Kingdom. Participants reported wavelengths of maximum absorbance together with the actual absorbances obtained. The results were compared with values obtained from the National Physical Laboratory. The results show a wide scatter, and several instruments were extensively repaired or replaced as a result of the survey. The most recently marketed machines had the best performance, and it is suggested that regular quality control and maintenance of the machines is vital. It is intended to set up a scheme for regular monitoring of spectrophotometer performance.

Wilbur Wright

The 48th Wilbur Wright Memorial Lecture, “Mathematics and Aeronautics” was given by Mr. M. J. Lighthill, F.R.S., before a large and distinguished audience at the Institution of Mechanical Engineers, 1 Birdcage Walk, on 19th May 1960. Dr. E. S. Moult, C.B.E., B.Sc, F.R.Ae.S., M.I.Mech.E., President of the Society, presided.As has become the custom, before the lecture was delivered the President presented the awards made by the Council for 1960 for outstanding contributions to aeronautics. In the unavoidable absence of the Secretary he was assisted by Miss E. C. Pike, M.A., A.F.R.Ae.S., Secretary of the Medals and Awards Committee and Editor of The Aeronautical Quarterly. The list of the awards presented on this occasion was published in the June 1960 Journal—(p. XXXII).The President, introducing the lecturer, reminded the audience that the Wilbur Wright Lecture commemorated the first manned, powered controlled flight by Wilbur Wright at Kitty Hawk, North Carolina on 17th December 1903. The first Wilbur Wright Memorial Lecture was held in 1913 and they had been held each year ever since, through two World Wars; in itself a wonderful record. The custom had been, and would continue to be, to have alternately a lecturer from the United Kingdom and a lecturer from the United States; last year the lecture had been by Mr. McCarthy of Chance Vought and next year again it would be by an American.The Wilbur Wright Lectures had been a most distinguished series by distinguished lecturers, and he was sure that the lecture that night would be in keeping. His pleasant duty was to introduce Professor Lighthill—or as they had to call him Mr. Lighthill now that he was Director of the Royal Aircraft Establishment, which was an even greater distinction. Mr. Lighthill was the youngest Director that the R.A.E. had ever had—that alone was a tribute to Mr. Lighthill's ability and his high standing in the profession. Before joining the Royal Aircraft Establishment Mr. Lighthill was Professor of Applied Mathematics at Manchester University, and for a time, after leaving Cambridge, had worked at the National Physical Laboratory where he applied the mathematics of Cambridge to the problems of aerodynamics. His lecture was on “Mathematics and Aeronautics” he would ask Mr. Lighthill to deliver the 48th Wilbur Wright Memorial Lecture.

Set Up

AS readers of the Journal will know the Department of Trade and Industry set up in 1971 a Marine Traffic Systems Steering Group, to commission and coordinate research and development relating to the problems of marine traffic behaviour and to consider practical measures which could be undertaken as regards the Dover Strait area. The Group comprises mariners, economists, scientists and administrators from the Department of Trade and Industry including the National Physical Laboratory, representatives of the Civil Aviation Authority, the Ministry of Defence and, more recently, the Chamber of Shipping of the United Kingdom and Trinity House. Hargreaves has recently described briefly some of the earlier work arising out of the Group's existence. This paper describes in more detail the activities of the Steering Group from the time of its first meeting in March 1971 to the present day (October 1973). Many of the results of this activity are already known to Members of the Institute as a result of the publication in the Journal of papers read at the Conference on Marine Traffic Engineering held at the N.P.L. in May 1972 and sponsored jointly by the Royal Institute of Navigation and the Royal Institution of Naval Architects.

A Company

InCentros Ltd and Erhvers-og Selskabsstyrelesen (hereinafter Centros),1 the European Court of Justice ruled that it is contrary to Article 52 (now Article 432) and Article 58 (now Article 48) of the EC Treaty for the authorities of a member State (in casu Denmark) to refuse to register a branch of a company formed under the law of another member State (in casu the United Kingdom) in which it has its registered office, even if the company concerned has never conducted any business in the latter State and intends to carry out its entire business in the State in which the branch is to be set up. By avoiding the need to form a company there it would thus evade the application of the rules governing the provision for and the paying-up of a minimum share capital in force in that State. According to the Court, this does not, however, prevent the authorities of the member State in which the branch is to be set up from adopting appropriate measures for preventing or penalising fraud, either with regard to the company itself, if need be in co-operation with the member State in which it was formed, or with regard to its members, where it has been determined that they are in fact attempting, by means of the formation of a company, to evade their obligations towards creditors established in the territory of the member State of the branch.

The last decade has seen the emergence and growth in this country, and elsewhere, of science parks. In 1984 the United Kingdom Science Park Association (UKSPA) was set up with eight founder members. The mushrooming that followed meant that by 1986 the Association could report 28 fully operated parks, seven others under construction and a number of Associate Members, of which Reading University was one.

Set Up

Originally set up in 1988, ARCLIB has become a lively pressure group involving not only architecture school librarians in the United Kingdom but also those in other European countries and the USA. National conferences have provided an annual focus and these are listed in the appendix, but there have also been active international contacts over the years, the current hosting of the ARCLIB discussion list in Venice being one example. ARCLIB also publishes its own Bulletin, which reports on the Group’s activities and keeps members in contact with one another.

1. Introductory .—Recently at the National Physical Laboratory we have constructed a standard of mutual inductance of novel type, whose value has been accurately calculated from the dimensions. This inductance has formed the basis for the determination of the unit of resistance in absolute measure by two different methods, in both of which alternating current is employed. Although there is no doubt that the accuracy attainable by these methods could be increased by greater elaboration of the apparatus used, the results already obtained seem to be of sufficient interest to warrant publication. It should be mentioned that the accuracy here aimed at was of a considerably lower order than that contemplated in the determination of the ohm by the Lorenz apparatus which is at present being carried out in the laboratory. For the experiments here described, no apparatus was specially constructed, but use was made of instruments which had already been designed and set up for the measurement of inductance and capacity. I shall first give a brief description of the standard inductance and then pass on to the methods and results. 2. Standard Mutual Inductance .—The design of the mutual inductance has already been described. The electrical circuits have the form and arrange­ment shown in section in fig. 1.
