Abstract: A method for detonation of a plug device in a fluid environment is described, which is in contact with a body, such as an ignition pellet, and it is characterized in that a number of pressure increases are exerted against the plug device, whereby each pressure increase causes a movement of a piston (10) which is radially arranged in a casing (12), which causes the casing (12) to move a fixed distance inward in the plug device with each pressure increase, up until the displacement of the casing (12) causes the piston to be displaced into a cavity (38), and the fluid environment enters the plug device via an inlet. Also described is a plug device which is in contact with a body, such as an ignition pellet, where the plug device is arranged to detonate after a number of pressure increases that are exerted against the plug device.

Abstract: A strip of membrane material is laminated to a wider strip of netting and then the longitudinal edges of the strip of netting are seamed together into a sleeve for receiving aggregate to form an elongated tubular drainage element. The laminated peripheral portion of the resultant sleeve is used as the top of the drainage element to preclude fine material from entering the drainage element. Where a membrane is used to form the sleeve, holes or slits are placed in the peripheral portion of the sleeve that is to form the bottom of the drainage element. The seaming of the overlapped longitudinal edges of the membrane is effected using glue and a nozzle that blows air under pressure onto the seam to force the edges and glue to bond together.

A downcomer and extension element together extends across the column and supports the panels of the mass transfer area.

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.

The mixing element has a cross-sectional design which increases substantially continuously from the first cross-section to the second cross-section. Flow-dividing layers are arranged in the mixing element such that a precise fitting of the mixing element into the substantially continuously expanding fluid-conducting means is made possible.

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 method of growing a fungal fruiting body requires exposing a mycelium of a desired organism type to environmental conditions sufficient to induce fruiting of fungal primordium in the organism type followed by enclosing the fungal primordium within a mold of a designated shape representing a near net shape volume of a desired final product. The fungal primordium is allowed to grow and fill the mold to form a mass of fungal tissue equivalent in shape to the designated shape of the mold after which the mass of fungal tissue is removed from the mold and dried.

Abstract: The test procedure for determining groove conformance employs a replicating compound to obtain a self-supporting mass with a negative image of the grooves of a club face. A thin test specimen strip is sliced from the mass and then scanned to form an electronic trace of the profile of the ribs. A negative image of the profile of the ribs is then obtained as a replica of the profile of the grooves and the grooves measured to determine conformance to USGA Rules. A protective covering may be placed on the self-supporting mass to insure the integrity of the ribs during slicing.

Abstract: The apparatus (1) which combines a heat exchange between a liquid (8) and a heat transporting medium (7) with a static mixing of the liquid includes installed structures (2) in a jacket (3). The jacket extends longitudinally between a head end (4) and a base end (5). The installed structures form a heat exchanging and mixing structure. The heat transporting medium can be conveyed from the base end to the head end as an inner flow in tubes (21, 22) of the installed structures. The liquid can be conveyed from the head end to the base end as an outer flow. Reinforcement elements (6, 6?, 6?) are provided which stabilise the installed structures in the longitudinal direction against pressure gradients generated by the liquid. The installed structures are connected by the reinforcement elements to form a non-expandable part structure (2a) in a main region; they remain at least partly non-reinforced as a longitudinally expandable part structure (2b) and in a secondary region complementary to the main region.
