Abstract

Last year a survey was made from the bibliographical point of view of six trade fair catalogues, based on a visit to four international fairs. This year this survey has been repeated on nine trade fair catalogues, B.I.F. London and Birmingham, Basle, Hanover, Milan, Paris, Brussels, Liege, Lyons, Utrecht, based on a visit to the first‐mentioned five trade fairs. In the original article it was stated that, owing to the large size of present‐day fairs, the catalogue is an indispensable means of information. The question was asked whether the catalogues provided the information the visitor wants in the shortest possible time. What can one fair learn from the catalogues of others, and in what way would the use in general be served? Compared with Table I of the original report it became evident that in the majority of cases the weight of the catalogues tends to increase still more. For instance, last year's Hanover trade fair catalogue had a weight of 28 oz. and has now increased to 39 oz. Only in the case of the Milan fair a real reduction was found, as this year only two parts were published, with a total weight of 60 oz., compared with a total weight of three parts of 79½ oz. last year. A slight weight reduction was also observed with the catalogues of the B.I.F. London.

Abstract

It is well known that notches have a deleterious influence on the fatigue strength of parts. A constant, the sensitivity index, is commonly used to relate the fatigue stress concentration factor to the elastic stress concentration factor. The author outlines a simpler hypothesis, which he claims to be a more reliable guide to fatigue behaviour in notches. Briefly it assumes that the elastic stress concentration factor gives the reduction in the fatigue strength due to the notch, but because of the local nature of the stress concentration, the endurance limit is increased according to a simple law. This increase in the fatigue strength depends on the smallness of the notch.

Abstract

This paper describes a mechanism which has six degrees of freedom, controlled in any combination by six motors, each having a ground abutment. It is considered that by its particular arrangement, this mechanism may form an elegant design for simulating flight conditions in the training of pilots. Unlike most simulators, it has no fixed axes relative to the ground, and therefore within the limits of amplitude of the design it can truly simulate the conditions of banking by carrying the simulation of control surfaces into the axes of the new attitude. Variations in control arrangements are described and their respective design merits considered. Other possible uses for this mechanism are mentioned including automation of production.

Abstract

In this series of articles, the author reviews some of the problems involved in the lubrication of by modern automobiles and suggests how the use of additive treated oils can assist in their solution. Later parts will cover oil quality, specifications, transmission oils, upper cylinder lubricants, etc.
