  • Patent number: 10345175
    Abstract: A pressure measurement pod for blood circuits can include a flexible, moveable, fluid-impermeable diaphragm and can be formed via either a one-shot or a two-shot molding process. A method of manufacturing a pressure measuring device can include providing first and second major mold parts having recesses defining major parts of a housing, and inserting pins in the first and second major mold parts, the pins being shaped to define a flow channel of a molded pressure measuring pod. One of the pins may have a major face that defines an internal surface of a diaphragm. The method may further include closing the first and second major mold parts with the pins therebetween and injection molding a pressure pod housing. Finally, the pressure pod is removed from the mold parts and the pins are withdrawn from the flow channel.

  • Patent number: 5999106
    Abstract: Apparatus and methods for monitoring a characteristic of fluid flow through a fluid dispenser that permit adverse flow conditions to be monitored, analyzed and displayed to an operator. The monitor samples either the static or firing pressure a predetermined number of times and calculates an average static and firing pressure over the sampling period. The average pressure values are compared to high and low warning and alarm limits and warning and alarm error codes are produced as a function thereof. In addition, individual sampled values are compared to the high and low warning and alarm limits and pressure values exceeding the limits during a sampling period are counted. Warning and alarm error codes are produced as a function of the counted values exceeding predetermined count values.

  • Patent number: 5755884
    Abstract: An apparatus includes a welding assembly which forms a seam in a tubular can body. A coating assembly applies coating material to an inner side surface of the seam. Coating material is conducted to the coating assembly through a main conduit. A monitor assembly, in the main conduit, includes a housing having an inlet valve and an outlet valve. An orifice is disposed within the housing between the inlet and outlet valves. A transducer senses fluid pressure downstream from the orifice. The inlet and outlet valves are operable to direct the coating material flow to and from a bypass conduit. This enables the orifice and/or the transducer to be repaired or replaced without interrupting operation of the coating assembly. In one embodiment of the invention, the monitor assembly is disposed ahead of the welding assembly and coating assembly. In another embodiment of the invention, the monitor assembly is disposed between the welding assembly and the coating assembly.

  • Patent number: 5405087
    Abstract: An apparatus for cleaning a coating gun nozzle used in spraying the inner surface of cans with a coating material comprises a cleaning nozzle of a cleaning gun for spraying a cleaning solution onto the spray nozzle to remove oversprayed coating material collecting thereon. The cleaning nozzle is secured to an end of an elongated cleaning gun extension and is positioned above a spray nozzle secured to one end of a coating gun extension for Spraying cleaning solution onto said spray nozzle. Cover sleeves, forming liquid-tight seals with the cleaning and spray nozzles, have removable friction engagement with the cleaning and spray gun extensions to shield the cleaning and spray guns from oversprayed coating material. A control system controls the operation of the coating and cleaning guns.
