This article derives the angular position equation of the driven links of the geared four-bar linkages and the common formula calculating the transmission ratio. Both the equation and the formula are applicable to the three-class, two-class and single-class epicyclic geared linkages. The conditions which the instantaneous dwells of the mechanisms must have are also introduced here. The article simplifies appropriately the mechanisms synthesis of some of the special mechanisms and position, and gives...

This paper deals with the macrokinetics of water gas shift reaction on commercial iron oxide catalysts. In an internal recycle gradientless reactor, type B106 and B109 shift catalysts of commercial size and cylindrical in shape, have been studied under atmospheric pressure. Reaction conditions were: temperature 350° to 480℃, molar ratio of steam to carbon monoxide 2 to 11, dry gas space velocity 150 to 1500ml/(h. g). Experimental results showed that the macrokinetic equations for both catalysts can be expressed...

This paper has derived a new method to calculate the critical temperature T_K, which, as the temperature increases, is yielded by the thermobending phenomena in the round-longer bar under four different conditions of binding, i.e. both ends hinged, both ends fixed, one end fixed whereas the other hinged, and one end fixed whereas the other free. The collocation method of MWR(Method of Weighted Residuals ) is used to analyse and calculate in this method, with which the common formula can be obtained for...

This paper has derived a new method to calculate the critical temperature T_K, which, as the temperature increases, is yielded by the thermobending phenomena in the round-longer bar under four different conditions of binding, i.e. both ends hinged, both ends fixed, one end fixed whereas the other hinged, and one end fixed whereas the other free. The collocation method of MWR(Method of Weighted Residuals ) is used to analyse and calculate in this method, with which the common formula can be obtained for calculating critical temperature T_K. The advantage of this method is that the calculation in simple, fast and exact. The method is an effective one in finding the approximate solution of differential equations.
