Abstract: 2134085 9320956 PCTABS00027 The present invention comprises a method for measuring the amount, i.e., mass, of a volatile liquid which comprises passing the mass (18) over a heat loss measuring device (6, 8), calculating the amount of heat loss accompanying the vaporization of the mass and correlating the heat loss to measurement of heat loss of known liquid aerosol mass made with the same device. The method is especially useful in assuring uniform metered doses among multiple aerosol containers (12).

Abstract: System for Inspecting and Recycling Goods from Defective Packages on a Blister Packaging Machine A pneumatic apparatus for withdrawing and recycling goods from detective blister packages on a blister packaging machine comprising a housing which is positioned on the blister packaging machine between the detection station and the sealing station and having a plurality of transversely spaced-apart open chambers in the bottom thereof. A plurality of air valves are connected to a high air pressure source and to the blister package machine detection station, and each air valve corresponds to a respective chamber in the bottom of the housing. A plurality of air venturi nozzles are provided wherein each air venturi nozzle is fluidly connected at its air pressure input end to a corresponding air valve and chamber. Each nozzle comprises a goods transportation conduit connected to its air exhaust exhaust end so the air venturi nozzle will create a partial vacuum in the chamber fluidly connected thereto and a pressurized air flow in the goods transportation conduit at the air exhaust end thereof when the air valve corresponding thereto is opened. Upon receiving a signal from the detection station, the pneumatic goods recycling apparatus will pneumatically withdraw the goods from predetermined portions of a carrier strip from which blister sections will be separated and which each have at least one empty cell therein and then propel the goods back to the blister packaging machine hopper.
