Abstract:
An apparatus and method for joining pipes includes a plate for melting mating surfaces of the pipes to be joined. Additionally, the apparatus utilizes a vacuum in order to push the first and second pipes together in lieu of hand or mechanical pressure which may be inconsistent. Additionally, the vacuum allows the pipes to be joined to settle on each other in order to create a pressure about a periphery of the end of the pipe being joined to the other pipe. The consistent pressure creates a very strong joint between the first and second pipes.

Abstract:
The device (1) is associated, in line, to an outlet of a packing machine and is designed to seal superposed flaps (Ls, Li) of packs (C), at longitudinal vertical sides (V) thereof. The device comprises means (2) for receiving and moving the packs (C) and two batteries (3, 4) of heat-welding rollers (30, 40), having a vertical axis, destined to act on respective longitudinal vertical sides (V) in order to heat the flaps (Ls, Li) up to a temperature which is sufficient to cause joining by aggregation of the packing material. Cooling means (5) are provided downstream of the batteries (3, 4) which are destined to act on the flaps (Ls, Li) in order to lower the temperature thereof and thus stabilise the join.

Abstract:
The invention relates to a microfluidic device for metering liquids into a microfluidic network. The microfluidic channels or chambers are at least partly formed by the introduction of suitable structures into a film above the substrate carrier, so that at least some of the flow of fluid through the network takes place above the plane of the substrate. In order to form a stable channel structure or chamber structure in the film, it is envisaged that in the edge zone between the unattached and attached portions a wedge of material is formed by the viscous flow of the film material as the film is bonded to the substrate, this wedge forming a transition between the chamber wall and the substrate and raising the chamber wall above the plane of the substrate. In one method of producing a finished microfluidic structure a flat planar film is laminated onto a flat sheet-like substrate. During the lamination a mask having at least one recess or opening is pressed onto the film and onto the substrate under pressure and/or under the effect of heat. The film is thereby brought to a temperature at which there is a viscous flow of film and/or substrate medium into the region of the recess or opening, so that a wedge of material is formed and the film bulges up in the region of the recess to form a chamber. The invention further relates to methods of metering at least one liquid in a microfluidic network, in which a capillary stop is overcome by actuating the film, the film being wetted as the capillary stop is removed.
