TL;DR: In this article, a wave-guide has a deposit on its surface consisting of a liquid crystal material, a source transmitting light along the waveguide and a means of measuring the light leaving the wave guide.
Abstract: A device for detecting organic vapours incorporates a wave-guide having a deposit on its surface consisting of a liquid crystal material, a source transmitting light along the wave guide and a means of measuring the light leaving the wave guide. The liquid crystal material is sensitive to organic vapour in that the organic vapour changes the power of transmission of the guide. The appts. gives a simple, flexible and rapid means of detecting and controlling organic vapours present in very small quantities in a gaseous medium, e.g. the atmosphere.

TL;DR: The records are divided into those obtained from the various 'Theaters of War' and considerable clinical material is included but this is so scattered and poorly presented as to be of little value.
Abstract: various fields of radiology in the wide experiences of the United States Army in World War II. The foreword notes the neglect in the documentation of information obtained in World War I and the failure in anticipation of the problems encountered in World War II. This contribution stresses the value of the recording of available facts in the organization for any further major conflict. The records are divided into those obtained from the various 'Theaters of War' and considerable clinical material is included but this is so scattered and poorly presented as to be of little value. An interesting feature is the description of the enormous routine radiological chest surveys organized for recruits and the various techniques that were used. In I944 a chest radiograph was a prerequisite in Physical Examination for Mobilization. Difficulties were naturally encountered in assessment of rejection standards with regard to calcified tuberculous pulmonary lesions. It was agreed that large lesions might break down under war-time circumstances and the criteria recommending that men could be accepted were as follows:

TL;DR: In this article, the authors proposed a self-mixing cell-structure which makes for good selfmixing of the respective flows of gases and vapours, while preventing self mixing in an axial direction.
Abstract: A drying process converts sticky phase sludge (44) with a dry residue of 50 preferably 65 % to a bulk dry granular condition with a dry reside of 80 preferably 90 %. The process comprises: (a) the sludge (44) is continually dried as it passes through the drying section (46) in contra-flow against dried sludge (44) and sludge vapour particles (49) without self-mixing of either the drying sludge or vapours, in the respective direction of flow (33, 50); (b) drying takes place by cross-flow mixing of the vapours and the sludge (44) with reference to the respective direction of flow (33, 50); (c) air is mixed in with the vapours at the end of the drying section (46) or in a subsequent vapour removal section (47), lowering the dry sludge temperature while minimising the water vapour particle pressure, and intensifying the drying process. Further claimed is (d) a continually-operated linear drying assembly (11) whose overall length is great in comparison to its cross-section; and (f) the assembly incorporates rotor (20) heat-transfer ribs (29), creating a cell-structure which makes for good self-mixing of the respective flows of gases and vapours, while preventing self-mixing in an axial direction.
