摘要:
A cartridge (2) for storing a plurality of test strips (32) suitable for analyzing body fluid, such as blood is designed such that the test strips (32) can be brought out of the cartridge (2) for performing a body fluid measurement. Such test strips (32) need to be identified in order to calibrate the measurement to lot- to- lot variations of test strips. The identification is accomplished by measuring the resistance of a resistor (9) attached to tne cartridge (2). The measurement of the resistance is carried out through a direct sensor - to - controller circuit using the RC timing method.

The present invention provides a packaging for a fiber optic component, such as an optical fiber, wherein the heating induced strain to the fiber optic component is minimized, wherein the packaging comprises a first support member having a first coefficient of thermal expansion (k1). The packaging further comprises a second support member, which is resiliently mounted to the first support member for minimizing transfer of thermal expansion induced strain of the first support member to the second support member. The second support member comprises a longitudinal groove open at least on one side of the second support member for receiving a fiber optic component, wherein the second support member has a tensile strength considerably higher than that of the fiber optic component. The second support member has a second coefficient of thermal expansion (k2) substantially smaller than the first coefficient of thermal expansion (k1), wherein the first support member is adapted to exchange heat induced by free-space radiation. The second support member is made of material, such as quartz, which is transparent to the wavelengths used in the component.

The present invention provides a cell tray (100) suitable for accommodating bottles of at least two different sizes. The novel cell tray (100) has a quadrilateral base (70) which has on one side a loading surface (71) adapted to receive bottle bottoms in a matrix-like loading pattern. The cell tray also includes holding devices (72) on the opposite side to the loading surface (71) such that the holding devices (72) are adapted to receive and lock into place bottle mouths of bottles loaded onto a similar cell tray (100) beneath said holding devices (72) in a stack of cell trays (100). The holding devices (72) are arranged as to align with at least two separate loading patterns (LP 1 , LP 2 ). The loading surface (71) comprises protruding ridges (73) which have a shape inverse to that of a combination of the first and second loading patterns (LP1, LP2).
摘要:
A method and a system for the automatic loading of air-transport units. In the method, the piece goods and the air-transport unit, on at least one side of which is an openable loading opening, are transported to the packing location, when the piece goods are packed automatically through the loading opening into the air-transport unit. The air-transport unit is tilted in connection with the packing, in such a way that the side with the loading opening is raised relative to the side opposite to the loading opening, so that the air-transport unit is loaded in at least two different attitudes.

Method, arrangement, and feed screw for feeding and compacting a concrete mass in an extrusion casting machine, which arrangement comprises at least one feed screw (5) for feeding the concrete mass and elements (8, 9) for rotating the screw (5), in such a way that its helix pushes the mass parallel to the central axis of the screw. Further, in the arrangement, there are elements (11, 12, 13) for moving the feed screw (5) forwards and backwards inside the mass. The feed screw (5) is shaped in such a way that the surface (16) of the side of the helical blade (15) of the feed screw (6), which is on the trailing side of the helix, is at least over part of the height (h) of the helix tilted in the direction of the trailing side, in such a way that a straight line (19) drawn from the intersection (17) of the helical blade (15) on the trailing side of the helical blade and the casing (14) of the screw to the point ( 18) of the helical blade, in the same cross-section, forms, over at least part of the length of the helix, an acute angle (a) with the central axis (K) of the screw in this cross-section.
摘要:
The present invention relates to a curtain coater and a curtain-coating method for coating a moving web (2) of paper or board. The curtain coater comprises an applicator nozzle (1) located above the web (2) to be coated so as to apply the coating mix therefrom to the surface of the web (2) in the form of a continuous curtain extending uniformly over the cross-machine width of the web (2). The boundary air layer traveling on the surface of the web (2) is removed by a doctoring means (3) which is located upstream in the travel direction of the web (2) in front of the impingement point of the coating mix curtain on the surface of the web (2) and is further located on the same side of the web (2) as the applicator nozzle (1).

Arrangement for mixing a liquid with a flowing solid substance, comprising a reaction chamber (1), a connection (2) for feeding the flowing solid substance to the reaction chamber (1), a connection (3) for removing the mixed substance from the reaction chamber (1), and a connection (13) for feeding the liquid to the reaction chamber (1). For mixing the liquid there are elements (10) for feeding the liquid to the reaction chamber (1) in the form of droplets and elements (11,12,15) for feeding a compressed gas to the reaction chamber (1). On the central axis of the reaction chamber (1) is preferably arranged a mixer shaft (6), which comprises elements (9-12) for feeding the liquid and the gas to the reaction chamber from the outer surface of the shaft (6).

摘要:
The present invention relates to a method and apparatus for coating a moving paper web (2), in which method the web (2) to be coated is passed to a coater station and the coating is applied to at least one surface of the moving web (2) by means of spraying nozzles (1) disposed in the interior of an enclosing hood (9). The web (2) is supported noncontactingly by means of air jets directed toward at least one side of the web (2) and air jets are aimed to blow outside the hood (9) blowing air from the air jets in a direction reverse to a travel direction of the web (2) in the hood aimed toward the exit slit (11) so that the air blown from the air jets prevents coating mix particles from escaping from the hood (9) through the exit slit (11).
