The closure system includes a means of encircling (5) that is integral with the first extremity (3) and arranged to evolve between a de-latching configuration, where the means of encircling (5) forms an open collar freeing the second extremity (4), and a latching configuration where the means of encircling (5) forms a closed collar designed to surround the second extremity (4) so as to unite it with the first extremity (3), the closed collar having opposite front (6) and rear (7) faces, between which an encircling opening extends that is designed to accept the second extremity (4).

Abstract: Network-units (4) comprising multicast driver devices (3) handle multicast messages efficiently by providing the multicast driver devices (3) with memory nodes (1,2) arranged in rows and/or columns, with a memory node (1,2) comprising a memory element (31-33) for memorising a state of the memory node (1,2). Large numbers of multicast cells/groups like multicast cells and/or multicast groups can be served advantageously. M×N memory nodes (1,2) are arranged in M rows and N columns, with a memory node (1,2) comprising an engagement line (11), an unavailability line (12) and an identification line (13) per row and a request line (21), an acknowledgement line (22) and a selection line (23) per column. A memory element (31,32) memorises a state indicating a destination port being used for a multicast cell/group, and a further memory element (33) indicates a state requesting a generation of a multicast copy for a destination port, all according to a rule of exclusiveness.

The heterocyclic ring has at least one substituent located at a ring position adjacent to a ring nitrogen atom. This mandatory substituent of the ring includes a moiety (B), linked to the heterocyclic ring via a carbon-carbon double bond, a carbon-carbon triple bond or an azo group. The mandatory substituent is positioned adjacent to the ring nitrogen atom. Invention compounds are capable of a wide variety of uses. For example heterocyclic compounds can act to modulate physiological processes by functioning as agonists and antagonists of receptors in the nervous system.

Abstract: A compact, highly flexible and efficient, multi-positionable, multi-dimensional and multi-stage gas-fired heat exchanger system as described. The system is connectable in a forced air duct regardless of the angular position and size of the duct. The heat exchanger comprises one or more heat transfer tubes which are shaped and dimensioned as dictated by the customized use of the heat exchanger. The tubes are secured to a support panel as well as the gas burner associated with each of the inlet openings of the tubes. A position orientable gas valve is secured to a gas distribution manifold. A turbulator may be associated with at least some of the tubes to cause turbulence in the hot combustion flow in each of the tubes to modify the efficiency in heat transfer along one or more sections of the tubes by directing hot combustion gas along an inner circumferential wall of the tubes.

Abstract: The present invention relates to encapsulated lactic acid, where lactic acid is in a solid, pure, crystalline form. The encapsulation of food acids is common practice. Many companies produce encapsulated citric, tartaric and sorbic acids or GDL. However, lactic acid, a major food acid for its flavour and conservation effect, is not available in a pure solid crystalline encapsulated form. As no substrate is needed for said coated solid lactic acid particles, the lactic acid content of said particles may be very high and the activity of the lactic acid is not impaired by the substrate. Furthermore, the encapsulated solid lactic acid particles according to the invention are easy to handle and are less expensive than encapsulated liquid lactic acid.
