Abstract: A pressurized dispensing package includes a container in which the product to be dispensed and a gaseous propellant are stored. The product is dispensed through a discharge passage that extends from a control valve to a terminal orifice. A plural passage flow control member is disposed in the discharge passage. Each passage of the flow control member has a flow dimension in the range of one to one hundred microns and the length of the flow control member several times the passage flow dimension so that a significant pressure drop occurs across the flow control member as the product flows through the member. The total flow area of the flow control passages disposed in the discharge passage is greater than the area of the terminal orifice but less than fifty percent of the area of the discharge passage in which the flow control member is located.

Abstract: Apparatus for the continuous feeding of plural liquids in separate streams of adjustable quantity and ratio, comprises a drive unit that drives a main pump, and that also drives at least one secondary pump. The drive unit has an oscillating or reciprocating movement, and so the pumps are piston pumps or oscillating vane-type pumps. The stroke of the secondary pump or pumps may be selectively shortened without shortening that of the main pump, so as to predetermine the proportions of the liquids to each other. The system is particularly applicable for the feeding of separate streams of synthetic resins by the main pump, and the associated hardeners, catalysts, accelerators or other auxiliary liquids by the secondary pump or pumps.

Abstract: A syringe of the slide piston pump type is adapted to overcome a pressure resistance at its outlet as may be provided, for instance, by a filter in communication with the outlet and through which the syringe is to pump a medium, particularly a liquid medium, for filtration. The syringe comprises a cylinder containing a piston, and a piston rod. The piston rod is fixed to a second piston sliding within a longitudinal bore in the first-mentioned piston. The bore and the second piston cooperate to define an air-filled pressure chamber connected to a cylinder chamber, defined by the first piston and the cylinder, by a valve. Inward movement of the piston rod produces an over-pressure (e.g. 16 atmospheres) in the pressure chamber to open the valve to apply the over-pressure to the liquid or other medium in the cylinder chamber to overcome the pressure resistance of the filter and enable the liquid to be forced through the filter.

Abstract: A container and dispensing package comprising an outer carton, an inner wrapper and an expendable tray. The outer carton comprises an enclosure to house the inner wrapper and expandable tray containing cube sticks of foodstuffs such as butter. The expandable tray comprises a single or unitary cardboard member folded to form a plurality of separate substantially U-shaped compartments of troughs. The inner wrapper is attached to the rear of the outer carton such that light pulling of the outer flap by the user pulls the expandable tray out of the carton in an accordion-like fashion leaving the cube sticks on the floors of the troughs whose sides or partitions have fallen away. Retainers are formed by cutting away portions of adjacent partitions to form flaps which lie against the top of the outer carton and act as guards to prevent the cube sticks from sticking to the inner wrapper so that they won't tumble out of the carton.

Abstract: Disclosed is a wheel having two staggered rows of surface-gripping, radially-yielding feet. When the wheel encounters an obstacle, a spring compresses, thereby permitting the feet to deflect and absorb shock that would have otherwise been imparted to the vehicle. While travelling on a smooth surface, the feet deflect an amount depending upon the load carried by the wheel. Since the shock absorbing spring is recessed in a cavity in the foot, the distance that a foot can deflect is increased.
