Abstract: The present invention provides a dry-powder inhaler device comprising: a casing; an air inlet located at a first terminus of the casing; a powder delivery port located at a second terminus of the casing, which is positioned distal to the air inlet; and an elongated assembly located within an interior of the casing. A first terminus is located proximally to the air inlet, a second terminus is located proximally to the powder delivery port, and the assembly is fitted within the casing such that said assembly partially rotates therein about a single axis. The assembly has at least one compartment containing dry-powder, which is located proximally to the second terminus. The compartment with a dry-powder comprises a porous structure encasing the dry-powder; whereby airflow through the device causes the assembly to partially rotate within the casing about a single axis and release the dry-powder in the airflow.

Abstract: A dry-powder inhaler device comprising an air inlet (40), an air outlet (4), an assembly comprising a mesh-based package (10) containing a dry-powder drug (16), the assembly being positioned to undergo agitation, the device having an airflow therethrough from the air inlet to the outlet, which airflow at least indirectly causes the agitation and wherein the agitation of the assembly in conjunction with the airflow causes the particles of the dry-powder drug to exit from the mesh-based package and become entrained in the airflow.

Abstract: A dry-powder, breath-powered inhaler device comprising at least one air inlet, a flow chamber and an air outlet leading to a mouthpiece, the flow chamber further comprising at least one drug-containing volume and at least one scraping means and a rotor assembly comprising an axis and at least one blade; wherein the inhalation action of the patient applied at the air outlet causes air to enter the at least one air inlet such that the air interacts with the at least one rotor blade causing the rotor to rotate and thus generate breath-driven, relative motion between the at least one drug-containing volume and the at least one scraping means, such that fine particles of powder are released from the drug-containing volume; the arrangement being such that the air exits the flow chamber via the periphery of the flow chamber, carrying out the fine particles to the outlet to be inhaled by the patient.

Abstract: An electronic spreadsheet, formed in accordance with the present invention, providing a user with improved data processing capability, includes displaying a visual presentation to the user, the visual presentation including a matrix, the matrix including columns, rows and cells, the cells being formed at intersections of the columns and the rows. The electronic spreadsheet associates objects and formulas with the cells, each object having an object type, each formula receiving an object as an argument, each formula having an operator for operating on the object received as the argument. Further, the electronic spreadsheet evaluates each formula, which includes assigning to the operator in each formula an operative expression selected in accordance with the object type of the object received as the argument of each formula. Still further, the electronic spreadsheet associates a result, obtained during the evaluating procedure, with each cell associated with each formula operating on the object.

Abstract: A wire connector including a first member and a second member defining a cavity therebetween, the first member including a first channel and a second channel, the second member including a third channel and a fourth channel, the first, second, third and fourth channels being in communication with to the cavity, forming a substantially X-shaped form, the X-shaped form including a substantially central point. The first and the third channels are substantially collinear. At least one of the first and the third channels having a first additional opening for accommodating a first wire. The second and the fourth channels are substantially collinear. At least one of the second and third channels having a second additional opening for accommodating a second wire. The winding of the wires is by rotating the first member relative to the second members substantially around the central point, thereby winding the first and the second wires of the wire pair.

Abstract: A device for injection of liquid fertilizer into an irrigation pipe includes an axisymmetrical housing (I) adapted for insertion into the pipe line (III). The device comprises an axial turbine impeller (II) rotatably positioned in the housing, the impeller including several vanes (20) surrounded by a shroud (22) and a flat, annular rim (6) outstanding from the shroud and closely surrounded by the housing walls. The rim contains, on one or on both of its flat sides, a side-channel pump of known design which includes a plurality of radial vanes (30) inserted into an annular portion of the flat side and a channel (33) recessed in the adjoining housing wall portion cooperating with the annular vane portion and extending from an inlet end (34) to an outlet end (35), the two ends being separated by a non-recessed wall portion (36).
