  • Publication number: 20040026338
    Abstract: The invention relates to a filter aid for filtering a liquid, such as beer, in a filtration device working on a defined filtration velocity, said filter aid consists essentially of particles of a material A, wherein the flotation velocity UoA is measured as Formula (I): wherein dA is the diameter of the particle, &mgr; is the viscosity of the fluid, r is the density of the fluid and &rgr;a is the density of the particle. The invention further relates to the use of said filter aid as a precoating material in a candle filtration device and to the candle filtration device comprising a number of candles provided with a precoat consisting essentially of the filter aid according to the invention and to a filtrated liquid, for example alcohol and more in particular beer, obtained via a filtration method using a candle filtration device.

  • Patent number: 6624218
    Abstract: The invention relates to compositions comprising at least one polymer and at least one plasticizer, in which compositions the polymer is semi-crystalline and exhibits a processing temperature equal to or greater than 220° C., preferably 250° C., and the plasticizer is an aromatic benzenesulphonamide represented by the general formula (I) in which R1 represents a hydrogen atom, a C1-C4 alkyl group or a C1-C4 alkoxy group, X represents a linear or branched C2-C10 alkylene group, or a cycloaliphatic group, or an aromatic group, Y represents one of the groups OH or R2 representing a C1-C4 alkyl group or an aromatic group, these groups optionally themselves being substituted by an OH or C1-C4 alkyl group.
