Tribology in Secondary Wood Machining

In the period of New Economic Policy in the USSR industrialization issues became very topical. In timber industry complex, the solutions were related to the development of forested areas in Northeastern regions of the country as well as to the construction and reconstruction of enterprises. The article provides the first-time analysis of maps and forest industry location, based on the results of the First Five-Year Plan published in the atlas “The Industry in the USSR and the beginning of the Second Five-Year Plan“ and statistical collection materials ”Social Construction of the USSR”. The analysis was made in order to define the situation in the industry, the main directions of production as well as the regional specificities. Using the example of wood machining sphere the author presents the analysis of enterprise groups according to different criteria. The research resulted in conclusions about highest intensity of enterprise reconstruction and construction in timber sawing, in furniture industry and intra-sectoral combination. In timber industry, the majority of enterprises were small and middle companies, which greatly contributed to its development. Regional specificities of timber industry location included concentration of main facilities in northwestern, western and central parts of the country, in the Volga region and in Ural. However only several regions had developed wood machining and deep processing spheres, such as Leningrad oblast, the Gorky Krai, Belarusian and the Ukrainian Soviet Republics.

As If

The Kidston Collection of fossil plant slides in the Botany Department of the University of Glasgow contains a number of sections of a very notable stem labelled “Lepidodendron textum, Kidston, n.sp.” No mention is made of this species in any of Dr Kidston's publications, but the correspondence relevant to the Collection indicates the history of the slides. This may be briefly summarised.As early as 1883, Dr Kidston had received from Mr J. Coutts two sections (Nos. 51 and 52) of this stem, which had been collected by the latter at East Kilbride, Lanarkshire, Scotland, from the Carboniferous Limestone Series of the Calderwood Beds (Hosie Limestone) in the Lower Limestone Group. Dr Kidston postponed description of this stem till he had better sections at his disposal; the specimen, however, was lost, and it was not till many years later that he rediscovered it in Dr John Young's collection in the Glasgow Municipal Museum, and had more sections cut from it (Nos. 1144–1153). No manuscript notes of Dr Kidston's descriptive of these slides have been found, with the exception of a pencilled reference in his manuscript slide catalogue, opposite Nos. 51 and 52, to the “foliar bundles—there is an appearance as if there was a development of secondary xylem, whereas the axial bundle has no secondary wood.”
