Abstract: Microwaves are respectively propagated through a reference fluid and fluid to be measured, both contained in a detection pipe body, and as a result, a first phase lag .theta. 1 and a second phase lag .theta. 2 can be determined on the basis of the microwaves by a phase lag measuring circuit.  Then, a density computing circuit subtracts the first phase lag .theta. 1 from the second phase lag .theta. 2 to determine a phase difference .DELTA..theta..  When computing the density of matter in the fluid on the basis of the phase difference .DELTA. .theta., the density computing circuit performs density computing processing such that a real second phase lag .theta.2 satisfies the following equation .theta.2 = .theta.2' + N x 360° where N is the number of rotations, and .theta.2' is an apparent phase lag obtained by the phase lag measuring circuit.  Then, if the density does not fall within a checking range defined by upper and lower limit values, a rotation-number checking circuit increases or decreases the number N of rotations such that the density falls within the checking range.

Abstract: A backflow valve for use in a post-mix carbonator system for preventing the backflow of carbonated fluid, thereby preventing the contamination of the fresh water supply, and indicating when such a backflow condition has occurred.  In a first embodiment the valve comprises a check seat body which houses an elastomeric valve member, and a sight glass body for viewing the position of the elastomeric valve member.  The valve also comprises top and base connectors for connecting the valve to the fluid carrying line and a shut-off/flush valve for controlling the flow of fluid through the device.  The elastomeric valve member allows the flow of fluid from the supply to the outlet when the fluid pressure at the supply exceeds the pressure at the outlet and prevents the reverse flow of fluid when the pressure at the outlet exceeds the pressure at the supply. As the pressure downstream increases, the elastomeric valve member is forced in the upstream direction over a plurality of steps in the check seat body.  As the elastomeric valve member passes over each step, it engages the step and is thereby prevented from moving downstream.  The position of the elastomeric valve member may be observed through a sight glass body which has a line marking the normal position of the elastomeric valve member.  In a second embodiment the elastomeric valve member is slidably disposed within a retaining chamber that is positioned between the upstream and downstream portions of the valve.  Under normal operating conditions, the elastomeric valve member is in a normal first position allowing fluid flow therethrough; however, in a backflow condition, the elastomeric valve member slides into a second position within the retaining chamber and fluid flow is restricted.  In addition, once the elastomeric valve member is in the second position, it is secured in place and a backflow condition is thereby indicated.

Abstract: On a mis au point des liposomes cationiques hautement efficaces servant de système d'apport amélioré pour des réactifs biologiquement actifs. Une nouvelle structure, le liposome en sandwich, est formée et comprend un ou plusieurs agents biologiquement actifs internalisés entre deux liposomes bilamellés. Cette structure protège l'agent arrivant et est responsable de l'efficacité élevée de l'apport in vivo et de la répartition tissulaire large des complexes de liposomes en sandwich. Ces nouveaux liposomes sont également des transporteurs hautement efficaces d'acides nucléiques. En utilisant des liposomes DOTAP:cholestérol extrudés pour former des complexes avec des protéines spécifiques de codage d'ADN, on a obtenu une amélioration spectactulaire de l'expression. Une expression maximum a été obtenue dans les poumons, alors qu'une expression accrue a été détectée dans plusieurs organes et tissus.

Abstract: Linear cold connection (1) with connecting places (12, 20, 23) contains a first and second structural component (2, 3) to join a first and second construction elements of a frame for road or rail bound vehicles. First construction elements are attached to the first structural component (2) and second construction elements are attached to the second structural component (3). The first and second structural components (2, 3) are joined together via a pair of first and second joint faces (5a, 5b). The joint faces (5a, 5b) form a length of arc of a circular cylinder with common circular-cylinder axis (16). The first structural element is joined to the second structural element (2, 3) via a bolt-type connection penetrating openings (17, 18) in the first and second joint faces (5a, 5b). The diameters of the openings (17, 18) transverse to the circular-cylinder axis (16) are larger than the diameters of the bolts (10) where they penetrate the openings (17, 18) with the result that, when the bolt-type connection is loose, both structural components (2, 3) can be displaced with respect to each other by relative movement of the first and second joint faces (5a, 5b) transverse to the circular-cylinder axis (16) and with that accommodate tolerances.

Abstract: The present invention provides a battery voltage measuring device capable of immediately detecting a breakage in the voltage measuring line in  a battery voltage measuring device that detects the battery voltage. In blocks formed by connecting a plurality of secondary batteries in series, voltage sensors that detect the voltage of each block are respectively provided. In addition, before these voltage sensors noise filters are provided, and in addition, a measuring line breakage detecting resistor for detecting a breakage in the voltage measuring line is connected in parallel to each block. In a battery voltage measuring device having this type of structure, in the case that the voltage measuring line Q is broken, the voltage values V1 and V2 detected by the voltage sensors 20-1 and 20-2 become voltage values that accompany the resistance ratio of the measuring line breakage detecting resistors 60-1 and  60-2. Thereby, the voltage sensor detects a voltage that is not normally detected, and as a result, it becomes possible to immediately detect the breakage in t he voltage measuring line.
