operation of which has been mastered and, therefore. not Included In the plan for the development of science and engineering); -modernization of equipment, structures and transport means Including that done In the course of overhaul: 351 -utilization of means of "smal I mechanization": various accessories, attachments, more· perfect tools. starting and adjusting devices, etc.J -partial Improvement of the employed technology and production methods, Including the Introduction of rationalization proposals and foremost experience at Individual stages of the produ-ct 1 on process and operatIons. Calculations by the factor "Improvement of uti I lzatlon and application of new types of raw materials and materials" consider the economy forming as a result of accomplishing measures for more rational utilization of raw materials and material resources, which Is not Jndlvated In the calculation by the factors stated earlier, Including: -Improvement of utilizing natural raw materials, In particular, by reducing Its losses at extraction, enrichment and primary processing, as wei I as most complete extraction of useful components when utilizing complex raw materials; -Improvement of utilizing raw materials In the production process (Improvement of cutting out, decrease of allowances for processing, Introduction of new recipes>; -utilization of substitutes, more economic profiles of rolled metal, more efficient grades of cement, etc. -more comp I et.e waste In production, secondary heat, etc. utilization of raw material recovery of used materials, and material utilization of Data on the reduction of norms of consumption -of material resources and the plan of measures for their economy are the Initial ones for calculattons by this factor <as by other factors associated with the uti I lzatlon of raw materials and materials). The effectiveness of measures for Improving the products and directed toward reducing their material and labour consumption. for example, the utilization of advanced constructl~n materials, reduction of the mass of the machines and equipment owing to
