Abstract: The present invention is a cuvette provided with at least two cavities. The first or inlet cavity takes up fluid by capillary action. The second cavity is a reception cavity which communicates with the first cavity through a first channel. The second cavity preferably is constructed and arranged to not exert a capillary action, although it could be constructed to exert a capillary action. The first channel which is in fluid communication with the first cavity and the second cavity exerts a non-capillary and non-spontaneous fluid transporting function that is operative only under an external influence, such as by application of a centrifugal force on the cuvette. The cuvette is well suited for a variety of analyses, particularly upon whole blood.

Abstract: A device for rapidly performing a sedimentation-rate test is described. A tube (17) containing a given amount of blood specimen is placed in a holder (13, 21, 22) which rotates (23) the tube (17) a predetermined number of revolutions at a given speed about an axis perpendicular to the longitudinal axis of the tube while rotating (24) the tube about its longitudinal axis, to then stop the tube for a given period of time about 60.degree. from the vertical, and to finally turn the tube (17) to the vertical position at a speed which is but a fraction of the first-mentioned speed also while turning the tube about the longitudinal axis. Means (26) are arranged to monitor the rotational movements of the tube, preferably by means of markings on a plug (18) closing the tube end.

Abstract: A cuvette for taking up a fluid and mixing the fluid with a reagent for analyzing the mixture consists of a body (10) of glass or polymeric material having a first cavity (12) in which the fluid can be taken up, preferably by capillary action, through an inlet (13), and at least one further cavity (21) exerting capillary force on fluid which is transported from the first cavity (12) into a reception cavity (17) by subjecting the cuvette to centrifugal force. The further cavity (21) preferably exerts capillary force through a wick (19) which does not extend as far as the bottom of the reception cavity (17), and a capillary channel (20). In those cases where more than one further cavity (21) is provided, each such cavity (21) communicates with a further reception cavity into which the fluid can be transported from the cavity (21) by the exertion of centrifugal force. The cuvette may also have cavities for receiving washing or diluting liquid, which are connected in series or in parallel with the cavity (12).

Abstract: In an attachment fitting for cylinder locks (3, 3') the heads (4a) of a plurality of screws (4) are seated in a widened hole portion (5a) in the lock. A plugging or latching element (6) is arranged to co-act with a sealing pin (7) in a manner such that when the plug (3a) of the cylinder lock (3) is turned to a given position by means of a key, the sealing pin (7) moves inwardly in a peripheral hole (9) arranged in the plug, against the action of a spring (10). This enables the plugging or latching element (6) to be removed. Because of the presence of the plugging or latching element (6), however, the screw heads (4a) cannot be reached in order to loosen the screws by persons not having the correct key to the cylinder lock. The screws connect the cylinder lock (3) to a further cylinder lock (3') on the other side of the door.

Abstract: In the packaging field certain types of packages are manufactured from pre-shaped, cylindrical casings made from a heat-shrinkable laminate. The casings are formed by winding a material sheet around a mandrel and subsequent sealing together of the overlapping ends of the sheet. However, because of the stiffness of the material the leading end of the sheet protrudes tangentially from the mandrel during the winding and prevents an accurate adaptation of the material sheet to the surface of the mandrel.According to the method and arrangement of this invention this disadvantage is avoided in that the leading end of the sheet is pre-heated on the side facing the mandrel to such a degree, that the shrinking is initialled. The shrinking of one side only results in that the leading end of the material sheet is given a curved shape with a radius that coincides with the radius of the mandrel, and consequently the leading end is no longer an obstacle to the winding.

Abstract: According to the invention, simple measuring apparatus (10) is produced which is designed to ascertain if a so-called spring strut (50) appertaining to the front wheel suspension in a vehicle has been deformed or more specifically if it has been bent, the apparatus being designed to be used primarily on wheels equipped with disc brakes. The apparatus is used in situ, i.e. on a spring strut (50) mounted in place in the vehicle, and it is necessary only for the wheel to be removed, with the tire and rim, so that the disc brake (40) is exposed. The measuring apparatus consists of an upright (12) which is attached to a base part (14, 20) designed to be attached, preferably by means of permanent magnets (24, 26), to the outside of the brake disc (40).
