Abstract: The specification discloses a closed system for cleaning, pressure testing, and drying fire extinguisher containers. The system comprises two tanks for holding trichloroethane and flow lines and a valve control system for flowing the liquid from one tank into the container to be cleaned, pressure tested, and dried and then from the container to the other tank. After a number of containers are cleaned and pressure tested and the second tank becomes full, the valve control system can be controlled to reverse the flow of liquid from the second tank to the containers to be cleaned, pressure tested, and dried and then back to the first tank.In a further embodiment, there is provided a universal head adapted to fit many different sizes of fire extinguisher container openings and in addition an adjustable holding device for holding the container to be tested between a support plate and the head and for inverting the container to allow the container to be emptied after the test is completed.

Abstract: Catalytic converter emptying and filling device attachable to the housing of a catalytic converter containing means therein defining a bed for storing catalytic pellets and further having a port therein for emptying the pellets from the bed and housing. The device includes a rigid conduit connectable to the port for passing the pellets to a receptacle or cannister rigidly attached to the conduit for receiving the pellets from the converter and further including a vibrating instrumentality rigidly attached to the device for imparting vibrational turbulence not only to the rigid assembly making up the device but also to the converter housing and the pellets therein to cause the pellets to pass rapidly from the converter through the conduit to the receptacle or in the opposite direction.

Abstract: Apparatus for filling containers with difficultly-flowable material, comprising a separator including a filter, a funnel-shaped outlet, and a dust-free butterfly valve for controlling flow of powder through said outlet; and a suction device for conveying said powder by suction to said separator; said outlet adapted to be connected to the container to be filled; said separator being operable to filter powder from the air conveying said powder into the separator and allowing the separated powder to fall into said funnel-shaped outlet. The invention is especially designed for emptying and filling fire-extinguishers.

Abstract: An apparatus for the rapid, accurate and sterile filling of unit dosage, injection syringes with medication from a bulk source container or for reconstituting vials of drugs. A clamping means is mounted to a support frame for releasably retaining the outer cylinder member of a disposable, relatively large-volume, pumping syringe against all movement relative to the support frame. A gripper means for removable attachment to the piston member of the pumping syringe is mounted to the frame for linear reciprocation along the axis of the pumping syringe. A crank means, which has an adjustable offset for selecting dosage volume, is drivingly connected to a motor drive means and an associated connecting rod links the crank means to the gripper means for reciprocally driving the piston member of the pumping syringe. A disposable, dual check valve, tee connector is connected to a mating connector on the pumping syringe.
