Title: Process and plant for removing dust from gases
Inventor: ALLOYER GUY
IPC: B01D47/06
Filed: 1986-06-25
Abstract: Removing dust from gases and process and device for separating very fine particles, smaller than a micron in size, from a gas stream at a high flow rate and in which the dust concentration is low. According to the invention the gas is subjected to a prewashing 10 by spraying a liquid into the gas stream, the particles are made to agglomerate by passing the gas stream through one or more venturis 12, a washing liquid is sprayed into the gas stream 16, the trapping of the dust by the droplets of the washing liquid is brought about by dividing the gas stream into partial streams which are projected one against the other 18 and the droplets are separated from the gas stream 20. The invention may, in particular, find an application in the removal of dust from the exhaust gases of prilling (nitrate or urea granulation) towers.

Patent FR-2609757-A1 (FR)
Title: Manufacturing section having distributed stresses and whose deformations are inhibited in the loaded operational state
IPC: F16D1/00
Filed: 1987-01-19
Abstract: The deformations due to the elasticity of the stressed materials and/or created by thermal expansion and/or induced by flow are built into the makeup of each component during the design phase so that the operating conditions imposed, which are normal under nominal load during use will be respected. The distribution of stresses becomes more uniform which increases the strength in an optimum fashion. The section to be manufactured is determined by successive approximations by simulating the nominal conditions by taking away the deformations which are evaluated so as to define the envelope to be machined. The method consists in evaluating or measuring the deformations. These are taken away by simulation or by successive modifications so as to obtain the envelope which will be reproduced in production on the components. The examples of application are threading with a differential pitch, the corrected involute and the directed stress shaft. Other means are necessary for manufacturing: orbital threading and see-saw cutting. They are described to solve the technical problem.
