Abstract: A mixer-feeder vessel for the percentagewise mixing of two or more liquids, particularly for offset printing presses, enables a fluid contained in the feeder vessel to be admitted to a fluid tank. A partial volume of the mixer-feeder vessel is subdivided into a predetermined number of chambers by means of partition walls, with the chambers arranged in adjacent relationship to form a row. The partition walls protrude from one wall of the vessel by a predetermined length into the vessel. In a wall opposite the one wall of the vessel there is provided an inlet-outlet port aligned with a first chamber of the row of chambers, so that when a liquid is supplied through the inlet-outlet port, the first chamber situated under the port is first filled and subsequently the remaining chambers along the row are filled in series. The opposite wall is spaced from confronting end sections of the partition walls by another length.

Abstract: The device, placed inside of the cartridge, container, tube, etc., makes it possible to maintain two different substances in chambers (6, 7) separate until the moment of use and then makes possible their mixing, and distribution of the mixture from a closeable (3) output opening (2) of cartridge, tube or container (1). The device comprises a membrane (4) easy to perforate or break (10) fastened to a fluidtight peripheral ring (4'). A perforated (13) disk (14) is provided with points (8) or the like for perforating or breaking (10) of membrane (4) at the moment of use. The disk is driven like a piston, by sliding (arrow 12) and/or rotation (arrow 17) of a rod (5) coming in a tight manner from container (1) to allow, by alternating movements, the intimate mixing of the two substances.

Abstract: The invention relates to a method and a capsule for the storage and mixing of the two co-reactive basic materials for dental amalgam. The capsule comprises an elastically bendable length of tube bent into V-shape with the arms each forming chambers and with the tip between the arms forming a point of separation between the chambers. Each of the basic materials is accommodated and stored in its own chamber and can be mixed by straightening out the length of tube, the ends of which are sealed, so that the point of separation is opened up, and by shaking the length of tube in its axial direction. The invention also relates to a method in manufacturing the capsule in which the tube length prior to bending into V-shape is pre-shaped in one section at the center of the length of the tube by providing two transverse points of compression which are mutually separated by an intervening section.

Abstract: An improved aerosol can agitator is described. An unbalanced, multi-pronged, agitator aids in more complete more thorough mixing of the contents of an aerosol can. Additionally, paddle-like devices on some of the prongs are utilized to increase the surface area to which pigment and other settled contents may adhere. The use of additional surface area to which pigment and other settled contents may temporarily adhere to aids in the mixing of the pigment with the carrier as the agitator is propelled throughout the carrier within the aerosol can. The unbalanced agitator results in a random, unpredictable agitation pattern thus aiding in more thorough mixing of the entire contents of the can.

Abstract: A flexible container comprises a receptacle divided into two chambers by an openable, fluid-tight barrier formed between the interior surface of the receptacle and the exterior surface of a hollow member contained in the receptacle. The barrier is maintained closed by a removable sealing band applied around the exterior of the receptacle. The removal of the band allows the wall surface of the receptacle to separate from the exterior surface of the hollow member, thereby opening a passage between the two chambers.

The second end of the sleeve frictionally engages the raised circumferential ribs on the mixing container during the mixing operation.

Abstract: The invention relates to a device for preparing and dispensing a solution. A bottle containing a substance to be disolved is closed by a disc-shaped base having a rigid rod thereon and a deformable head. A tube of solvent is closed by an apertured slidable piston. Mixing is effected by placing the piston against the rigid rod and applying axial pressure which dispenses the solvent from the tube, through a capillary channel in the rod and into the bottle. Slots in the rod are revealed during this operation to allow the air to escape from the bottle. The deformable head also serves to pressurize the bottle to permit dispensing therefrom.

Abstract: A soft contact lens container is disclosed for the immersion, preservation, optical measurement, shipping and dispensing of soft contact lenses. The container has an overall cylindrical shape with the cylinder sidewalls divided into mating portions for confining the soft contact lens as well as a liquid saline preservative solution. The cylinder ends are each closed by identical frustrated cones, each cone intruding from the cylinder end and into the cylindrical volume interior of the container. The respective cones from each cylinder end are frustrated by optical flats and confront one another with a small spatial separation so that the soft contact lens is trapped therebetween. Cylinder diameter is chosen to restrict the soft contact lens from passing between the two optical flats of the cone frustrum. In operation, one cylindrical section is filled with soft contact lens saline solution.

Abstract: A large diameter ball is placed within the sample cavity of a liquified petroleum gas sample vessel or cell. After the sample has been taken, the entire cell may be shaken to cause the ball to break up stratification, and to mix the sample. When a vessel or cell is emptied, a ball fits within hemispherical cavities between a piston and an end. The large diameters of the ball and cavities result in shoulders or ledges, which are less than half the diameter of the ball, so that they do not prohibit the movement of the piston because the ball will be forced into the cavities regardless of the orientation of the cell.
