Patent FR-2527945-A1 (FR)
Inventor: HAWRYLENKO ALEXANDER
IPC: B07B1/38
Filed: 1983-06-03
Abstract: In known vibrating machines, the vibrating table is connected to the frame by means of two or more cranks, these cranks generating the gyratory movement of the table and at the same time preventing the table from rotating or pivoting about any vertical axis. The disadvantage of such arrangements is essentially that a high accuracy is necessary to prevent natural oscillations from occurring. In the vibrating machine according to the invention, there is only one crank (3) which connects the frame (1) to the vibrating table (2) and which serves for generating the gyratory movement, and in addition there is a parallel guide, known per se, which prevents the table from rotating about its vertical axis. As a result, the accuracy requirements are appreciably lower and no difficulties arise as a result of thermal variations in length.

Patent FR-2566676-A1 (FR)
Title: Continuous mixing device
IPC: B01F5/04
Filed: 1984-07-02
Abstract: Devices for continuous mixing of liquid/liquid, liquid/gas and gas/gas phases enabling a liquid or gaseous substance to be distributed rapidly and uniformly in another liquid or gaseous substance in the form of a very fine dispersion. The principle of the invention lies in the introduction and distribution of the substances to be mixed with other substances by means of distribution nozzles with a solid jet, a solid cone or a hollow cone. The nozzles are housed in a chamber which is made up of two spherical spaces. The substance to which another substance is to be fed enters the lower space and moves towards the upper space through a constriction ring which separates the two spaces. The substances to be injected leave the nozzle at a speed which is much greater than that of the main stream and enter the depth of the lower space, where they are distributed into the reaction mass in the form of very fine droplets. The constriction ring produces an increase in the speed of flow of the reaction mass, and this gives rise to the formation of turbulence which further promotes the quality of mixing. The nozzle can move vertically in relation to the constriction ring; in this way it is possible to vary the constriction section between the two spaces, and this permits variable speed gradients. The most advantageous applications of the invention are in the fields of water and sewage treatment, of addition of auxiliary substances to a reaction mass and wherever mixing operations between liquids, gases and liquids, and between gases need to be performed.

Title: Flexible swimming pool which is rapidly self-erecting
IPC: E04H4/00
Filed: 1984-07-31
Abstract: The invention relates to swimming pools or pools, particularly those made of strong waterproof fabric. The pool is characterised by a tank whose free edges 1, which, when it is empty, collapse completely or partially towards the centre, are provided on the inside or on the outside with stiffeners 3, with covers 5 and, on the inside, with floats 4 such that, at the start of filling, the water does not escape and, after a short filling, with the pressure of the water acting on the walls 1, the latter erect themselves automatically by the combined action of the stiffeners 3 and of the floats 4 thus placing the wall 1 perpendicular to the bottom 2, which permits the swimming pool to be used with a variable depth of water. Application: to all pools and particularly to swimming pools made of strong waterproof fabric.
