A comparative physiological trial of four types of personal load-carrying equipment.

Abstract: FROM time immemorial the soldier has carried his knapsack over a shoulder or on the back. It cannot be said, however, that the advantages of an upright posture have as yet made him into an efficient beast of burden. The pack animal, on the other hand, is deliberately trained. for porterage; it largely exercises its own will with regard to the speed of travel, imd is protected by the load being normally limited to less than a quarter of the body weight, By comparison, the soldier is poorly treated. Porterage, which may on occasion play a major part in his activities, is completely subordinated to his operational role. His upright posture makes him a very poor animal for load carriage; nevertheless he is still expected to carry at least a third of his own weight, and this he must do from the small platform of his feet through which gravity acts. Although stability is of paramount importance, antero-posterior balance is often neglected or may be difficult to obtain, and by reason of his having to carry a rifle or other weapon, lateral symmetry may well be impossible. The soldier must be able to see well, turn rapidly, and move with changing speed and direction. Military requirements are constantly at conflict with physiological principles. Thus one must consider problems of silhouette, manreuvrability, accessibility of items of equipment, and changing types of warfare. The best that can be hoped for in his method of load carriage is an acceptable compromise, in an equipment which meets the overriding operational requirements with minimum sacrifice ,of the physiological principles which make for ideal load carriage. The turning point in the development of personal load-carrying equipment in the British Army came with the work of Parkes (1) and the Committee of 1865-1868 (2), as a result of which the following principles were enunciated:

The freezing and melting of some sulphur chloirdes

Abstract: Freezing and melting curves were obtained for pure sulphur dichloride and pure sulphur monochloride, and for mixtures of the two. Because the mixtures contained very little free chlorine, the usual deposition of higher chlorides did not obscure the phase behaviour, which showed that the following compounds were stable at low temperatures: SCl2, freezing and melting at 151° K.; S2Cl2, freezing and melting at 191° K.; and an intermediate compound, probably S2Cl3, freezing and melting at 145°k. No compound corresponding to S3Cl4 was indicated; all mixtures containing from 20% to 50% of sulphur dichloride showed a rapid fall in temperature during freezing. The phenomena associated with the freezings are described; and evidence for the formation and persistence of the intermediate compound at room temperature is discussed.

The design and operation of a 30-MeV synchrotron

Abstract: The paper outlines the constructional and electrical features of a 30-MeV synchrotron. Two types of magnet are described, and theirperformances are compared. Details are given of the accelerating chamber, with its evacuating system, and of the electronic equipment required to control and monitor the machine in operation. The general behaviour is discussed with the help of experimental results. These include the effects of misalignment and disturbance in the magnetic field, gas scattering of the electrons, variations in the injection process, and change in the parameters of the r.f. accelerating field.
