Title: Hardening and/or drying soft sticky particles - falling through treating column contg. inclined staggered partitions to avoid agglomeration
IPC: F26B3/26
Filed: 1981-07-15
Abstract: The arrangement is intended for treating sticky particles with a plastic consistency such as artificial gravel, fertiliser pellets etc. in a continuous process to harden them by direct or indirect application of a drying and/or treating medium. The particles pass under gravity through a treating chamber provided with partitions which are arranged such that the particles are sub-divided into shallow stacks to limit the pressure exerted on the particles by their weight. Used for treating and/or drying sticky pellets etc with plastic consistency in continuous process to harden and/or dry them. The arrangement prevents agglomeration and crushing of sticky particles under their own weight during treatment.

Title: Self-pumping tyre
Inventor: SIMEONOV IVAN KH
IPC: B60C5/00
Filed: 2001-11-12
Abstract: The invention can be used for all types of tyres which are pumped by air, The self-pumping tyre comprises two chambers, one of them pumping the other one during the travel of the transport vehicle, due to the pressure difference between the two chambers during their periodic pressing between the metal wheel and the road surface. The pumping chamber is several times smaller than the pumped chamber, and when pressure between the metal wheel and the road surface is exercised, the pressure in it becomes higher. By means of a valve (1), the air enters the other chamber. In the following moment of revolving the wheel, the metal wheel presses the pumped chamber, in which the air cannot get out, and the pumping chamber is freed from pressure and returns its original form under the elasticity of the material of which it is made, wherein it intakes air from the atmosphere across a one-way valve (2, 3). The cycle is repeated until pumping of the chamber reaches the state that the tyre walls of straightened and the pumping chamber cannot be pressed by the metal wheel. 1 claim, 2 figures
