Abstract: A chewing gum composition comprising; (a) a gum base; and (b) at least one microencapsulated composition comprising at least one active component and a matrix to at least partially microencapsulate the at least one active component; the at least one active component comprising at least one oil-soluble flavoring agent and the matrix comprising dewatered protein precipitate.

Abstract: Fuel tank comprising a canister containing a composition capable of retaining fuel vapours and which is associated with an overfill prevention device also located inside the tank.

Abstract: A shut-off device for progressive regulation of the flow rate of a fluid flowing in a pipe includes a main shut-off member which is able to pivot independently about a spindle passing through the pipe in order to close the latter, and at least one drive flap able to pivot about the spindle and act mechanically on the main shut-off member in such a way as to turn it about the spindle. The main shut-off member also being traversed by at least one orifice that can be closed by at least one shut-off flap, which flap can also pivot about the spindle, is integral with the drive flap and can regulate the rate of flow of the fluid through the orifice. The main shut-off member only begins to pivot about the spindle, from an initial closed position, when the drive flap is at a predetermined non-zero angular distance &phgr; from the said member, thus allowing the fluid to flow only through the orifice until the main shut-off member begins to open.

Abstract: Shut-off device for progressive regulation of the flow rate of a fluid flowing in a pipe (1), comprising(a) a main shut-off member (3) able to pivot independently about a spindle (4) passing through the pipe and close the latter, and(b) at least one drive flap (5) able to pivot about the spindle (4) and act mechanically on the main shut-off member (3) in such a way as to turn it about the spindle (4); the main shut-off member (3) also being traversed by at least one orifice (6) that can be closed by at least one shut-off flap, which flap can also pivot about the spindle (4), is integral with the drive flap (5) and can regulate the rate of flow of the fluid through the orifice; the main shut-off member (3) only beginning to pivot about the spindle (4), from an initial closed position, when the drive flap (5) is at a predetermined non-zero angular distance .o slashed. from the said member, thus allowing the fluid to flow only through the orifice (6) until the main shut-off member (3) begins to open.
