This article is a summing up of the general laws of the derailment accidents of four-axle wagons running on reversed curve tracks of small radii. The cause of wagon derailment is analysed according to the influence of cant, the runoff along the trans ition curve, and the slack at the side hearing of the wagons and non-central loading of goods. A formula for computation is presented for the maximum ratio of the reduction of the wheel loading caused by the fouraxle wagon wheels passing through the transition...

Briefly introducing the principle of operation of the sliding-vane rotary flowmeter,a reasonable design of the chamber profile in this kind of flowmeter is suggested in this paper with the intention of meeting such technical requirements as higher metering accuracy and less counting loss,wider metering range,less pressure loss,lower vibration and noise,steady rotation and less metering error due to the viscous property of the fluid metered.For the reason given above,the cycloid,taken as a transition curve of the chamber profile connecting two arcs with different curvature radii,is a substitute for the elliptic curve proposed in an earlier paper[1],thus preventing the impulse due to the radial acceleration caused by the elliptic curve.The theoretical and practical formulas of the chamber profile are shown as in formulas (6),(9) and (11) respectively,and the oscillating angle (pressure angle)λ and the minimum width of sliding-vane are also given.Finally,the possibilities of the smooth motion of sliding-vane and of the use of form milling to manufacture the chamber profile are also discussed.
