Patent FR-2556708-A1 (FR)
Inventor: BELOT DOMINIQUE
IPC: C01B33/04
Filed: 1983-12-19
Abstract: Silicon hydrides are produced by acid hydrolysis of ternary silicon alloys. According to the process there are made to react an industrial ternary alloy of the formula MxM2ySiz, in which M1 is a reducing metal, M2 is an alkali alkaline-earth metal, with a dilute acid selected from hydracids and orthophosphoric acid, at a concentration of 2N to 6N, by adding the ternary alloy in the form of fine powder to the acid, the reaction being preformed between ambient temperature and 90 DEG  C. The various hydrides are condensed, and separated by fractional evaporation under partial vacuum. The silicon hydrides-silane, disilane and higher polysilanes-after purification can be used as silicon vectors, depending on their chemical nature, particularly in the industries of electronic components, photovolaitic cells, photocopier drums and for frosting light bulbs by the dry method.

Title: Process and device for draining a pile of a wet granular material
Inventor: CONDOLIOS ELIE
IPC: F26B5/00
Filed: 1984-02-14
Abstract: The process comprises the following operations: - bringing wet material to form a pile 4 so as to allow the water to flow away by percolation over the height of the pile 4 while saturating the material situated in the lower part of the latter and causing free water to appear; - removal of the free water from the lower part of the pile so as to prevent the free water level from rising; - removing drained material from a "withdrawing" level which is sufficiently raised above that of the free water. It is characterised in that the pile 4 being produced on an area 1 for draining water, the part 6 of the pile situated between the draining zone and the withdrawing level, called a passive zone, is employed as a filtering zone used for protecting drains placed in the draining zone and preventing their blocking, this passive zone 6 being reserved for the draining of a number of piles deposited on it successively, before being replaced when it begins to be blocked.
