Abstract: A male adaptor is provided with a nose for penetrating into a housing of the female connector. A septum is disposed over the nose of the male adaptor to maintain a seal with the female connector during coupling and uncoupling. Upon coupling, the septum dilates to allow the nose to pass through. The female connector may have a septum that also dilates to allow penetration of the nose of the male adaptor. Alternatively, the septum of the female connector may be retractable under the force of the nose of the male adaptor.

Abstract: The device (1) serves for the generation of a discrete liquid phase in a continuous liquid phase with a first or a second liquid. The two liquids coexist as separate phases, have different densities and permit a desired exchange of material. Provision is made to arrange the device in a container (9) which contains the second liquid forming the continuous phase. The device includes a distribution member (2), in particular a cylindrical tube, and a collection passage (3) for the first liquid in a horizontal longitudinal extent. The collection passage has an outlet side (4), a collection side (5) and at least one side wall (6) connecting the outlet side and the collection side. The side wall establishes a connection between the outlet side and a horizontal drip edge (7). This side wall has a shape and an inclination which enables the formation of a liquid film of the discrete liquid phase. For enhancing the stability of the Film, the side wall (6) can have a good wettability for the first liquid.

Abstract: This invention relates to a method and a device for purifying and/or separating preferably high melting organic raw products or compound mixtures containing, in particular, high melting and/or degradable sterols, by layer crystallization on first heat exchanger surfaces. The raw product is received in a solvent or solvent mixture, and then brought into contact with heat exchanger surfaces. The desired product crystallizes on the heat exchanger surfaces by slow cooling. Solvent evaporating during the crystallization or sweating process is condensed and returned to the mixture.

Abstract: The network system matches the supply and demand of transportation services by incorporating unused transportation capacity (i.e., empty seats) with a real-time allocation and matching service that enables individuals and goods to conveniently hire that capacity with attractive pricing, rapid responsiveness, better information availability and trusted security. The network system provides an electronic registry of capacity containing an indication of the spare transport capacity and location of a plurality of transport vehicles, an electronic registry of demand containing an indication of the demand for transportation needs of a plurality of individuals and a central processing capability to effect a match of the transport capacity of at least one transport vehicle with the transport demand of at least one individual.

Abstract: A device is described for a plug (12) for pressure testing of bore holes and the like in a formation or the like, and associated pipe (10) in which the plug is installed in a plug-carrying chamber (14), and the plug (12) seals the passage through the pipe by cooperating with sealing bodies (23, 25), with the underside of the plug (12) being arranged (rests) in a seat at the bottom of the chamber. The plug is characterized in that it comprises a number of layer-formed or tier-formed ring disc elements of a given thickness, on fitted on top of the other.
