Abstract Most of the flame-retardant technology now used with elastomers has been known for some time. Advances have been made in recent years in the understanding of elastomer combustion and inhibition mechanisms, in the measurement and control of visible smoke generation from elastomers, and the toxic effects of combustion atmospheres. By integrating existing technology with recent developments and the likely advances of the future, elastomeric materials will continue to receive acceptance for a wide variety of applications. Author's note: A review stressing quantitative aspects of polymer combustion has recently appeared.

In 1939, Community Chests and Councils, Inc., published a pamphlet in its series on community planning, “giving tested procedures for determining the extent of social breakdown in the community, and outlining a detailed plan for better co-ordinated service to social breakdown families.” Because of the significance of the procedure and plan to social case work and requests from our readers for some discussion of it, the Editorial Advisory Committee of The Family planned a symposium from the point of view of case work, community organization, research, sociology, and psychiatry. Bradley Buell, of Community Chests and Councils, was invited to discuss the background of the plan. We shall be glad to receive other brief discussions for the Readers' Forum.

Introduces a STC89C51 microcontroller core with the speed of measurement and control system, the system can control the motor starts and stops, either manually or automatically adjust the duty cycle to control the motor speed is set by the Hall sensor data, for motor speed is measured to calculate and display the current motor speed in real time on the LCD. The system is made in the actual measurement with good results, as the research engine performance provides an important reference, so that the entire digital measurement speed system can be widely used, there is a strong practicality.

The grinding process is surveyed and a technique is described which enables the efficiency of the grinding wheel, coolant, and machine tool system to be determined. The analysis is made in terms of the maximum possible depth of cut that can be taken by the individual grits of the grinding wheel and the volume of material removed from the workpiece at this loading per unit volume of grinding wheel lost. Suggestions are made for the practical application of the technique to minimize the residual stress which is produced by the grinding operation. The results which have been achieved are shown in graphical form, and suggestions are made for the full explanation of the technique.
