The Shell Middle Distillate Synthesis(SMDS) plant now operational at Bintulu, Malaysia, is the latest in a series of partnership projects between Shell companies and the people of Malaysia that stretches back for more than 100 years. The new plant uses advanced technology to convert natural gas, abundantly available from the Central Luconia field offshore Sarawak, into liquid fuels of high purity. These fuels can also be used as components to upgrade lower quality stock derived from conventional crude oil processing. In addition, the plant can produce high-value waxes, as well as feedstocks for detergents and lubricants. The product mix can be varied to meet market needs. The SMDS technology was developed at the Shell laboratory in Amsterdam(KSLA) over a period of 20 years. After commercial and technical assessment, Bintulu was chosen in preference to sites in other parts of the world as an appropriate location for the employment of SMDS technology in the first commercial plant.  2, fiche 17, Anglais, - Shell%27s%20middle%20distillates%20synthesis%20technology

Some motors use an ingenious field system designed for a d. c. machine which operates on thyristor power supplies. The poles used consists of stacks of "C" shaped laminations which divide the yoke into four separate parts(for a four-pole motor) which are integral with the opposite halves of adjacent poles. This is called the Dynalam field system with split main poles [developed by the Electro Dynamic Construction Co Ltd](...). The advantage of this split-pole arrangement is illustrated in Fig. 8. 7 which gives a diagrammatic comparison of flux distribution in the field system of Dynalam motors and conventional d. c. machines.  1, fiche 25, Anglais, - Dynalam%20motor

Line graphs differ from each other by differences in scale rulings. The most commonly employed are the arithmetic and semilogarithmic rulings.(...) Arithmetically ruled graphs are designed to show changes in absolute amount.(...) Even when an arithmetic graph is properly constructed, it has severe limitations(...) [First], it is difficult to compare relative rates of change in the series. Second, when series that differ greatly in magnitude are compared, it frequently becomes difficult to determine the extent of the fluctuations in the series with the smaller values. Third, an arithmetic graph does not help the reader to determine whether one series of data is increasing or decreasing at a more rapid rate than other series on data that are plotted in the same field.(...) In order to overcome these limitations [one can] use semilogarithmic ruling rather than the conventional arithmetic ruling for line graphs.  1, fiche 28, Anglais, - arithmetic%20graph

Les graphiques arithmétiques rendent de grands services lorsqu'il s'agit de comparer des valeurs absolues (...) Les graphiques arithmétiques ne doivent pas être utilisés pour représenter les variations relatives, car ils les déforment; ils deviennent inutilisables quand il s'agit de représenter des variations qui, très petites à l'origine, deviennent considérables par la suite. Il faut alors les remplacer par des graphiques logarithmiques ou semi-logarithmiques.  1, fiche 28, Français, - graphique%20arithm%C3%A9tique

The "Enslin"(...) method [of induction profiling] employs a straight grounded-wire as the source. The horizontal component of the field which is tangential is measured along semi-circles about one of the electrodes. Measurements are not made near the wire in order to avoid the region of strong primary fields. The measurements can be made with conventional turam or radio reference equipment, or with other specialized equipment.  1, fiche 29, Anglais, - Enslin%20method

[La] "méthode d'Enslin" [est une méthode de sondage électromagnétique,] conçue et mise au point par J.F. Enslin (1955) (...) [Cette méthode fait] l'emploi d'un câble relié au sol par deux électrodes ponctuelles et dans lequel circule un courant, alternatif. Le câble connecté à une génératrice de courant sert de source de champ magnétique primaire. La composante horizontale du champ résultant tangente à la surface du sol est mesurée le long de demi-cercles autour d'une des électrodes ponctuelles. On n'effectue pas de mesures le long de câble afin d'éviter la région des champs primaires de grande intensité. On effectue les mesures à l'aide d'une unité turam ou tout autre équipement spécialisé de ce genre. Le champ tangentiel résultant demeure constant suivant le demi-cercle autour de l'électrode ponctuelle si le sous-sol est homogène (...)  1, fiche 29, Français, - m%C3%A9thode%20d%27Enslin
