  • Patent number: 8684239
    Abstract: An apparatus for pulsed dispensing of liquid. The apparatus includes a syringe body structure communicating with an input passage for pressurized actuation air, and communicating with an exit passage for allowing discharge of the liquid. An air input passage flow air controller is operative to increase the flow rate of the input air in accordance with a relationship that depends at least partially on a reduction of liquid volume in the syringe body structure resulting from a previous pulsed dispensing operation.
    Type: Grant

  • Patent number: 6121890
    Abstract: An electronic indicator that includes a means for a scaling the actual displacement of the spindle by a user-adjustable scale factor representing the ratio of the actual displacement of a spindle to the value displayed. The indicator includes a body, transducer assembly, controller, and display. The transducer outputs a value representing the spindle displacement to the controller. The controller converts the value to standard length units and scales the standard units by the desired ratio of the actual displacement to the displayed value, as set by the user prior to use of the indicator.
