Abstract: A system for automatically painting the external wall of a building, in which a support is suspended from a hoist apparatus disposed on the roof of the building, and a painting apparatus is supported by the support in such a manner as to be movable horizontally. The painting apparatus includes a mechanism for advancing and retracting, in a direction normal to the wall surface, a painting hood having a spray gun disposed therein, a mechanism for swinging the hood laterally, and a frame formed of mounted on the peripheral edge of an opening of the hood which opposes the wall surface. When the painting is positioned opposite the wall surface, the frame is brought into close contact with the wall surface, thereby sealing the painting hood against the wall surface and preventing any scattering of paint mist. Since the painting hood has no rollers, it causes no degradation in the quality of the painted wall surface.

Abstract: When maintaining a flow of a mixture of products consisting of a liquid of low to medium viscosity incorporating solid particles at a certain temperature and for a certain period of time the mixture remains for some time in a vessel of a substantially cylindrical shape. The residence time in the vessel of the solid particles mixed with the liquid is controlled separately from the liquid in that the solid particles are carried through the vessel at a regulable speed, independently of the speed of flow of the liquid through the vessel, with the aid of a rotatable conveyor means which is permeable to liquid but not to the solid particles and whose axis of rotation coincides with the axis of the vessel. The solid particles remain mixed with the liquid. The residence time of the solid particles is regulated such that the core of the solid particles attains the same temeprature as the liquid, without the liquid remaining for too long a time at the desired end temperature.
