摘要： A compressor station having at least one primary compressor and a booster compressor is controlled to conserve energy and air, and to respond quickly to sudden changes in demand for air, by employing a volume bottle to buffer changes in air pressure and by recycling already compressed air from the intake to the output of the booster compressor. The system may be used in air drilling and to provide compressed air for generating low density drilling fluid on site by injecting microbubbles into a base drilling fluid. Two different methods of generating microbubbles are illustrated. The primary and booster compressors are kept in a state of readiness during drill pipe connection time, providing for a rapid resumption of pressure and air flow after connection is completed. The system can utilize gases other than air.

摘要： Aqueous fluids are heated or boiled in a tank or vessel by causing cavitation in the fluid within the tank or vessel. A rotor having cavities on its cylindrical surface is rotated within a closely dimensioned housing submerged in the fluid, deliberately causing cavitation which heats the aqueous fluid without the use of flame or heat exchange surface. An electric motor which powers the rotor may itself be submerged in the tank or boiler vessel. The rotor includes radial channels for imparting centrifugal impetus to the fluid as it flows toward the cavitation zone.

摘要： Membrane tubes or similar membrane devices are arrayed in layers so that liquid placed on their outer surfaces may be evaporated and also drain onto lower membrane devices. The entire array is subjected to moving air to enhance evaporation. The membrane devices function as filters while permeating water from industrial fluids while also providing evaporative surfaces to reduce the volume of used aqueous industrial fluids. The retentate surfaces of the membrane devices may also be on the interiors of the devices, and the permeate contacted with flowing air to evaporate the permeate. Unevaporated permeate is collected in either configuration for use as clean water, and concentrated fluid may be more easily handled, disposed or, and/or its components recycled. A cavitation device may be used to heat the aqueous industrial fluid to enhance permeation and evaporation rates with minimal scaling.

摘要： A method of maintaining a constant movement of a cutting blade of an ultrasonic waveguide includes providing an ultrasonic transducer operable to convert a received motional current into a movement of a cutting blade of an ultrasonic waveguide, a measurement circuit connected in a parallel configuration with the ultrasonic transducer, and a variable power source operable to supply current through a set of connection points to the parallel configuration and thereby create the motional current in the ultrasonic transducer. Current is supplied through a set of connection points of the parallel configuration with the variable power source to, thereby, create the motional current in the ultrasonic transducer and the motional current is regulated with a current controller by varying an output of the power source, thereby maintaining a substantially constant rate of movement of the cutting blade across a variety of cutting loads.

摘要： A surgical stapling instrument includes a handle having a stapler-closing device. A surgical stapling end effector is connected to the handle and has a pair of opposing stapling surfaces. At least one of the stapling surfaces is operable to move with respect to the other of the stapling surfaces upon actuation of the stapler-closing device to apply a compressive force to tissue therebetween. At least one variable member is operable to receive the compressive force applied to the tissue and to exhibit at least one of mechanical and electrical change associated with the received compressive force. The change influences a surgical procedure on the compressed tissue.

摘要： An electrically powered surgical instrument includes a surgical end effector having a surgical procedure effecting actuation assembly. A handle is coupled with the end effector. An electric motor is disposed within a shell of the handle and has power terminals and a drive train actuating the assembly when the motor is supplied with power. A break-before-make power supply switch at the handle selectively controls supply of power to the motor. A post-termination braking circuit electrically short-circuits the power terminals when the switch does not supply power to the motor. A method for post-termination braking of an electrical motor utilizes the permanent magnetic field of the motor to counteract an inertia-induced over-stroke characteristic of the motor, drive train, and/or actuation assembly after powered operation by short-circuiting the still-spinning motor to create an electrically generated magnetic field in opposition to the permanent magnetic field upon ceasing supply of power to the motor.

摘要： A medical device includes a control handle having an articulation joint actuator, a surgical end effector, and a passive articulating joint connecting the end effector to the control handle. The articulation joint actuator, when unactuated, holds the passive articulation joint and, thereby, the end effector, in a substantially fixed articulation position, and, when actuated, releases the passive articulation joint into a freely articulating state to permit free articulation of the end effector with respect to the control handle dependent upon external forces acting upon the end effector. A method for operating the end effector includes retaining the passive articulation joint in a stable position with an articulation lock and actuating a release of the articulation lock to unlock the passive articulation joint and, thereby, permit articulating motion of the end effector through the passive articulation joint dependent upon the external forces acting upon the end effector.
