Abstract: A dispenser for flowable materials in which the flowable material is moved from a reservoir for such materials into a variable volume measuring chamber, the volume of which is adjustable only by an external key, and thereafter to a discharge opening remote from the measuring chamber, which opening has a closure to control dispersion of the granules.

Abstract: A measuring, metering, and mixing can, particularly for gasoline and oil, including a gasoline container with filler cap and spout; and oil container with filler cap; visual type gauges for each container; and a plunger-cylinder metering unit for withdrawing a selected amount of oil from the oil container and injecting the same into the gasoline can for producing an oil-gasoline mixture. The visual gauge on the gasoline container and the visual gauge on the oil container permit the metering of an exact amount of oil, dependent upon the amount of gasoline within the gasoline container for a precise ratio of oil-gasoline in the mixture. A hinged cover on the can protects the metering equipment during periods of non-use.

Abstract: Portable liquid measuring and dispensing device comprising a main reservoir for containing oil and to which a chamber is connected for metering a predetermined quantity of oil, this chamber being solid with the main reservoir and having a visual indicator showing the quantity of liquid contained in the chamber. The device includes a liquid moving assembly solid with the reservoir and the chamber, this assembly being formed of a rotary pump brought into rotation by a D.C. motor connected to a power source including a polarity inverter switch having a pair of buttons, each actuatable to cause rotation of the pump in one of its two directions of rotation.

Abstract: A filling machine for supplying predetermined quantities of liquid is disclosed. The filling machine comprises a measuring chamber, a float positioned with clearance in the chamber and adapted to move up and down in at least a portion of the chamber with the level of liquid in the chamber, an abutment positioned in the chamber above the float for limiting the upper movement of the float in the chamber, and a seal adjacent the abutment for sealing against the chamber, the seal being arranged such that it can be moved into and out of sealing engagement with the chamber without disassembly of the filling machine thereby facilitating cleaning of the machine.

Abstract: A liquid dispenser includes a metering chamber with a piston assembly movable therein for variance of the chamber volume and a supply chamber capable of liquid communication with the metering chamber. A hollow valve body with valve seats communicating with the metering and supply chambers and with a dispensing outlet is positioned between such chambers. A valve member is located within the valve body and is actuable by a control mechanism such that it is given an operating cycle whereby during one operating cycle the valve member is actuated into a first position to close the valve seat communicating with the supply chamber and to permit communication between the metering chamber and dispensing outlet and is maintained in the first position for a period of time sufficient to permit the emptying of the metering chamber through the dispensing outlet.

Abstract: A liquid dispenser having a metering chamber and a supply chamber disposed in side by side relationship and adapted for liquid communication with one another through a normally open supply valve. The liquid in the chambers are maintained at the same level. An outlet drain from the metering chamber through which liquid may be drained from the metering chamber and a normally closed outlet valve for controlling the flow of liquid through the outlet drain is provided. The supply valve and said outlet valve co-operate in such manner that upon opening the outlet valve to dispense liquid from the metering chamber, the supply valve closes and then subsequently re-opens for replenishing the metering chamber from the supply chamber only after the outlet valve has closed.

Abstract: Apparatus for selective controlled volume and rate administration of parenteral solutions, blood and the like, wherein sight and flow control problems caused by splashing and foaming of fluids having high surface tension such as blood are substantially diminished, and flow rates during different time phases of operation are optimized due to an arrangement of structure providing an increased head pressure on flow of fluid to a measuring chamber.BACKGROUND OF THE INVENTIONAdministration sets for delivery of parenteral solutions, blood and the like, have been heretofore available to the medical profession, which included volumetric chambers that allowed accurately measured volumes of solution to be administered to a patient. Volumetric sets of this type are especially essential for delivering discrete small volumes to infants and young children who could not tolerate larger, unregulated volumes of fluids. Volumetric control sets of this type are disclosed in prior U.S. Pat. Nos. 3,216,418 and 3,216,419.
