Abstract: A bulk dry food product storage, display and dispensing apparatus is described. In the apparatus there is provided a plurality of modules. In each of the modules there is provided a plurality of hoppers. Each hopper comprises a pair of side wall members and a curved bottom member. The curved bottom member comprises a front portion and a rear portion. The front and the rear portions each comprise a continuously changing radius of curvature, the continuously changing radius of curvature on the front portion being different from the continuously changing radius of curvature on the rear portion such that fresh product being added to the hopper from the rear thereof by being dumped on the rear portion of the curved bottom, slides down the rear portion, moves existing product forwardly and upwardly and displaces the existing product being supported on the front portion, causing it to fall on top of the fresh product moving therebeneath.

Abstract: Reusable pressurized containers are disclosed for dispensing fluids from the container without release of the pressurized propellant to the surrounding environment. The propellant is contained in a sealed, flexible compartment positioned within the container as a mixture of gas and liquid under pressure in equilibrium at the temperature of the container. A pressure transfer liquid, such as water or compressed air, is used to liquefy the propellant in the compartment. The pressure transfer fluid also contacts the fluid or semi-solid to be dispensed and exerts pressure thereon to force the fluid to be dispensed out of the container. The liquefied propellant, as it vaporizes, maintains the pressure against the pressure transfer fluid essentially constant. The propellant in the flexible compartment is preferably a mixture of a liquefiable propellant gas or blend thereof and a non-liquefiable inert gas such as nitrogen or helium.

Abstract: A machine for the attachment of rivets, buttons, or the like, particularly to clothing pieces, with an upper tool and a lower tool and with magazine chambers for upper and lower parts, from which chambers the upper and lower parts, respectively, are brought via feed rails into the region of the working position. The magazine chambers are arranged floor-like one above the other. A single slide is coordinated to both chambers, the slide being moved up and down in front of the rear wall of the chambers. On its front wide face the slide is equipped with stroke and sorting ledges which are inclined downwardly in the direction of one of the side walls. In the upper position the ledges lie flush in alignment with the discharge openings of the magazine chambers - side walls.

Abstract: This spice rack comprises a cabinet divided into a plurality of cubicles and, within the cubicles, a plurality of removable spice boxes. Each spice box comprises a front wall, a back wall, and a partition parallel to the front wall dividing the box into a large-volume dispensing chamber between the partition and the back wall and a small-volume reserve chamber between the partition and the front wall. The front wall is transparent so that spice stored in the reserve compartment is readily visible from the front of the cabinet when the spice box is located in its associated cubicle. Each spice box has a top with perforations therein communicating with the associated dispensing compartment to allow spices to be dispensed therethrough. These tops are effectively imperforate where aligned with the associated reserve compartments.

Abstract: A container for liquids includes a mixing cartridge extending from a gasket into the neck of the container. The mixing cartridge is asymmetrically disposed with respect to the container to allow a piercing member extending into the container from the cap of the container to be disposed in the container without piercing the cartridge in a storage position. The cartridge is pierced and the contents of the cartridge are mixed with liquid in the container by relative movement of the cartridge and the piercing member of the container so that the piercing member will extend through the cartridge both to pierce the upper and lower surfaces of the cartridge and to provide a flow-path for the contents of the cartridge into the container.

Abstract: A dual-compartmented easily separated composite container is provided having a first chamber or tank containing a pressurized substance such as a sanitizing or insecticidal material and another chamber for supplies mounted below the first and supporting it. The top of the supply chamber is sealed by the lower end of the tank. The invention also provides a supply chamber suited for attachment to existing pressurized containers.

Abstract: A servicing kit for chain saws comprising nested compartments which collectively have an external symmetry with respect to the longitudinal bisector of the structure, said compartments having interior walls, one of which projects into the interior wall of the other to an extent such that the ratio of the volumes of the compartments to each other is approximately two-to-one, a compartment included between the interior walls constituted by a diagonal depression in one of the walls which terminates short of the bottom and is open at the top and a carrying handle at the top.

Abstract: An osmotic system for delivering an agent is disclosed. The system comprises a wall surrounding a compartment and has a passageway through the wall for delivering agent from the compartment. The wall is formed of a material permeable to the passage of an external fluid and impermeable to the passage of agent. The compartment contains an agent that is soluble in the fluid and exhibits an osmotic pressure gradient across the wall against the fluid, or the compartment contains an agent that has limited solubility in the fluid and exhibits a limited osmotic pressure gradient across the wall against the fluid. The compartment also contains a suspending agent and a delivery member for increasing the amount of agent delivered from the system. The delivery member comprises a semipermeable film surrounding an osmotically effective compound and it is able to increase in volume over time.

Abstract: An osmotic system for delivering a beneficial agent is disclosed. The system comprises a wall surrounding a compartment and has a passageway through the wall for delivering agent from the compartment. The wall is formed of a material permeable to the passage of an external fluid and impermeable to the passage of agent. The compartment contains an agent that is soluble in the fluid and exhibits an osmotic pressure gradient across the wall against the fluid, or the compartment contains an agent that has limited solubility in the fluid and exhibits a limited osmotic pressure gradient across the wall against the fluid. The compartment also contains means for increasing the amount of agent delivered from the system. The means comprises a film surrounding an osmagent with the film formed of a material permeable to fluid, impermeable to osmagent and movable from an initial to an expanded state.

Abstract: An osmotic system for delivering a beneficial agent is disclosed. The system comprises a wall surrounding an agent compartment and an osmagent compartment separated by a film and has a passageway through the wall for delivering agent from its compartment. The wall is formed of a material permeable to the passage of an external fluid and impermeable to the passage of agent and osmagent.
