Abstract
THE report of the Industrial Research Bureau, Government of India, for the year 1938–39, covers work carried out on the development of Indian industrial research and industry by the Bureau, including that of the Industrial Research Council and of the Research Branch of the Government Test House, Calcutta. The Bureau itself has been responsible for work on casein plastics and has shown that high-grade rennet casein is required, while the resin at present produced in Indians of the lactic acid type, which is inferior for this purpose. A modified technique for the preparation of rennet casein suitable for operation under Indian climatic conditions requires development by laboratory investigations. The Bureau has also examined the economic and technical possibilities of manufacturing both rayon and staple fibre in India by the viscose, as well as by the acetate, process. It has continued its co-operation with the Central Standards Office Railway Board in matters concerning the lubrication and painting of railway rolling stock. With the view of developing the manufacture in India of phenol and formaldehyde for use in synthetic resins for moulding powders, disinfectants, etc., arrangements have been made for investigations of crude tar acid and phenol-cresol products from the cold distillation plant in Bihar. The Indian Lac Research Institute at Ranchi has obtained promising results in developing a shellac-urea-formaldehyde moulding powder.
