Abstract: A process for preparing an S,S?-dialkyldithiocarbonate from a dialkyl disulfide and from a particular metal catalyst, in the presence of carbon monoxide is described in addition to the use of S,S?-dialkyldithiocarbonates as reagents for the preparation of polycarbonates, compounds containing at least one urea and/or isocyanate function and compounds containing at least one thioalkyl function.

Abstract: A controlled-release multilayer microparticle containing a pharmaceutically active compound, which is intended for oral administration or direct administration in the stomach, which may be done using a liquid pharmaceutical composition containing the microparticle. The microparticle may include: a core that includes the pharmaceutically active compound, which may be pramipexole; a controlled-release intermediate coating layer; and an outmost external protection coating layer surrounding the controlled-release intermediate coating layer. The external protection coating layer may include a mixture of: a hydrophilic gastro-soluble component which is insoluble in aqueous media at a pH of between 6.5 and 7.5; and a hydrophobic and/or insoluble component.

Abstract: A foundation waterproofing assembly for cracked foundations includes a panel that is flexible and water resistant. A plurality of slats is coupled to and extends substantially perpendicularly from the panel. The slats are positioned in parallel on the panel and extend from a top to a bottom of the panel. The panel is configured to bend into a curved configuration such that the panel is insertable into a recess adjoining at least one crack in a foundation. The panel is configured to direct water entering the recess from the at least one crack to a point below a floor abutting the foundation, such that water is prevented from penetrating to the interior of the structure.

Abstract: The present invention concerns controlled-release multilayer microparticle containing a pharmaceutically active compound, said microparticle being intended for oral administration or direct administration in the stomach in the form of a liquid pharmaceutical composition.
