  • Patent number: 10441345
    Abstract: A generator is disclosed to generate a drive signal to a surgical device. The generator includes an ultrasonic generator module to generate a first drive signal to drive an ultrasonic device, an electrosurgery/radio frequency (RF) generator module to generate a second drive signal to drive an electrosurgical device, and a foot switch coupled to each of the ultrasonic generator module and the electrosurgery/RF generator module. The foot switch is configured to operate in a first mode when the ultrasonic device is coupled to the ultrasonic generator module and the foot switch is configured to operate in a second mode when the electrosurgical device is coupled to the electrosurgery/RF generator module. The generator further includes a user interface to provide feedback in accordance with the operation of any one of the ultrasonic device and the electrosurgical device in accordance with a predetermined algorithm.

The conditioner has a second portion adapted to be disposed in the pipe and in juxtaposition with the first portion. The second portion extending inward toward the center of the pipe in an upstream direction with respect to the fluid flow relative to the pipe's inner surface. An apparatus for determining fluid flow in a pipe having ultrasonic transducer sites. A method for determining fluid flow in a pipe. A method for affecting fluid flow in a pipe.

  • Patent number: 6244289
    Abstract: A vent assembly for a double case, rotary positive displacement meter permits venting of the outer housing chamber and inner mechanism chamber simultaneously through a single port in the outer housing to prevent damage to the rotor of the inner mechanism. A float/reed switch assembly can be provided to provide an indication of the need for venting if the vent is manually operated, or to automatically vent if an electrically operated valve is used.

  • Patent number: 4241354
    Abstract: Apparatus for indicating unauthorized delivery of liquid product for use in connection with a Veeder-Root Counter-Printer is characterized by a timer arrangement adapted to measure the time duration of an interruption in liquid product flow and to prime the printer's sale sequence number for incrementation if the duration of the interruption exceeds a predetermined time interval. If flow is resumed before the same ticket is removed from the printer, a nonsequential sale sequence number is imprinted on the ticket when it is removed, thereby providing an indicia that flow has been interrupted for at least the predetermined interval.
