The specific heats of rubber compounds are very important not only for the thermodynamic calculations in various rubber processings; mixing, extrusion, calendering, and vulcanization, etc., but also for the service life of the final products under repeated stressing conditions. In this study, the sp

β¦ Synopsis
A STUDY for publication of some 55 Β° tests of the burning of I84 different coals from all parts of the United States and from foreign countries has been completed by the fuel section of the Pittsburgh station. These burnings were conducted in four different domestic boilers. The average efficiencies and itemized heat losses have been plotted against the coals and their characteristics. The results are interesting and show very good curve uniformity, and indicate what may on the average be expected from a coal whose composition and burning characteristics are known. Although such plottings have the limitations pertaining to all averaged statistical data, yet it is believed that the publication when issued will be of decided interest to boiler manufacturers and heating engineers.

Here we present the detailed analysis of the specific heat data of selected intermetallic compounds RNi 4 Al for R ΒΌ Ce; Pr; Nd, and Dy. To determine the magnetic entropy of these compounds, the zero-field specific heat data were measured in the temperature range 2-300 K. The data of magnetic RNi 4
Kirwan first made its specific heat 0.05 ; Dalton gave it as the same ; Dulong and Petit obtained 0.0298 by the method of cooling. Regnault obtained 0.03244 (12'-98'), with gold ggg fine. Violle worked with gold 1,000 fine, and obtained for o"-~ooo 0.0316. This is stated to remain sensibly constant
