The present invention discloses a high intensity ultrasonic treatment method and apparatus that is used in conjunction with an existing commercial dough or batter mixer to enhance the rheological, aeration and textural properties of the dough or batter. This change in properties is a result of the phenomenon of acoustic cavitation induced in the dough or batter by treatment with high intensity ultrasonic waves. The present invention discloses a mixing bowl (20) of an existing mixer system that is preloaded with dough or batter, the bowl (20) is located at the center of an ultrasonic bath tank (101) filled with a working fluid. The effect of ultra-sonic waves with power levels above 1 kW can be observed over the entire or partial mixing period of the dough or batter. The ultra-sonic waves of the present invention are generated by a plurality of ultrasonic wave generators (104A, 104B) and piezoelectric transducers (1) mounted on a stainless steel tank (101). The electrical energy received in each transducer (1) will be converted into appropriate mechanical expansion and contractions in the piezoelectric ceramics of the transducer (1) thus leading to pressure waves being transmitted to the dough or batter to be mixed. The generation and transmission of high intensity ultrasonic waves to the dough or batter affects its rheological, aeration and textural properties.

Disclosed herein is a GO-Gd-DTPA (gadolinium-diethylenetriamine pentaacetic-graphene oxide) complex, which is formed by an ester bond of graphene oxide (GO) and gadopentetic acid (Gd-DTPA). Since the GO-Gd-DTPA can stably exist in the body because it has high stability in water, it is expected that it can be effectively used as an MRI contrast agent.

A trash spearing tool and method are provided. The tool includes a spearing pin, a trigger assembly, an inner tube, and an outer tube. The trigger assembly is movable between a normal position and an activated position. The outer tube is slidable between a storage position and a use position. The spearing pin is operatively coupled to the trigger assembly in such manner that, when the outer tube is in the use position and the trigger assembly is in the normal position, the spearing pin is normally biased to an extended position in which a portion of the spearing pin extends from the outer tube and, when the outer tube is in the storage position and the trigger assembly is in either the normal position or use position, the spearing pin to in a retracted position in which the spearing pin does not extend from the outer tube.

Apparatus and methods for ultrasound transmit switching are provided. In certain implementations, a transmit switch includes a bias polarity control circuit, a bias circuit, a first high voltage field effect transistor (HVFET), and a second HVFET. The sources of the first and second HVFETs are connected to one another at a source node, the gates of the first and second HVFETs are connected to one another at a gate node, and the drains of the first and second HVFETs are connected to an input terminal and an output terminal, respectively. The bias circuit and the bias polarity control circuit are each electrically connected between the source node and the gate node. The bias polarity control circuit can turn on or off the HVFETs by controlling a polarity of a bias voltage across the bias circuit, such as by controlling a direction of current flow through the bias circuit.

An X-ray arrangement is suitable to record absorption, phase contrast, and dark field images of an object. The visibility of low absorbing specimens is improved and required radiation dose is reduced. The assembly includes an X-ray source; two or more gratings; a position-sensitive detector with spatially modulated detection sensitivity; a recorder for recording the images; an evaluator for evaluating the intensities for each pixel to identify the characteristic of the object for each individual pixel as an absorption and/or a differential phase contrast and/or an x-ray scattering dominated pixel. Images are collected by rotating from 0 to n or 2n either the sample or the assembly. The gratings are produced with planar geometry. The X-rays pass through the gratings parallel to the substrate. The grating structures extend along the X-ray path which determines the phase shift. The attenuation of the X-rays caused by the grating structures is no longer given by the thickness, but by the length of the grating structures.

A method for ultrasonically inspecting components with wavy or uneven surfaces. A multi-element array ultrasonic transducer is operated with a substantial fluid layer, such as water, between the array transducer and the component surface. This fluid layer may be maintained by immersing the component in liquid or by using a captive couplant column between the probe and the component surface. The component is scanned, measuring the two dimensional surface profile using either a mechanical stylus, laser, or ultrasonic technique. Once an accurate surface profile of the component's surface has been obtained, data processing parameters are calculated for processing the ultrasonic signals reflected from the interior of the component that eliminate beam distortion effects and reflector mis-location that would otherwise occur due to the uneven surfaces.

Tip body has tubular shape with pointed-end opening and rear-end opening, rear end that can be attached to ultrasound scaler body, and intermediate curved part. Optical fiber is thinner than minimum inner diameter of tip body and has rear end toward which light from light source can enter. Optical fiber is inserted from rear-end opening to pointed-end opening of tip body, and has intermediate part that is in contact with curved part, so that end is vibrated by ultrasonic vibration of tip body. Ultrasound scaler body houses liquid supply device, ultrasound-generating device, and light source, which is attached to rear end of ultrasound scaler tip. Light source causes light for sterilization in predetermined wavelength range to enter rear end of optical fiber.

An apparatus for processing a sample of fibers and trash, having a cylinder for receiving the sample. Pins extend from the surface of the cylinder and retain the fibers. A knife extends along the cylinder adjacent the pins, and removes the trash that is not retained by the pins. The trash is separated from the sample along a downward direction. A counter-flow of air in an upward direction is directed towards the cylinder, where the velocity is sufficient to blow the fibers that are not originally retained by the pins up toward the cylinder, and yet is insufficient to prevent gravity from pulling the trash downward.

An apparatus for processing a sample including fibers and trash, having a cylinder rotating in a first direction for receiving the sample. The cylinder has a surface with rigid pins. The pins engage and retain the fibers of the sample. A collection surface receives the trash that falls from the cylinder. A counter-flow of air moves in a separation region between the cylinder and the collection surface in a direction that is substantially perpendicular to and towards the underside of the cylinder. The counter-flow of air has at each position within the separation region an air-flow velocity that is sufficient for the counter-flow of air to blow the fibers that are not originally retained by the pins up toward the cylinder and thereby engaging the fibers with the cylinder, and yet insufficient to prevent gravity from pulling the trash downward through the counter-flow of air.

An ultrasonic-rotary composite atomization mechanism comprises a housing and an ultrasonic unit passing through the housing and free to rotate with respect to the housing. A dynamic unit is installed in a position of the ultrasonic unit, which is corresponding to the housing, to drive the ultrasonic unit to rotate with respect to the housing. The ultrasonic unit includes a material supply channel, a vibration member disposed in the ultrasonic unit, and a vibration-rotation cup connected with the material supply channel. The material supply channel carries a liquid into the vibration-rotation cup. The dynamic unit and vibration member operate simultaneously to make the vibration-rotation cup rotate at high speed and vibrate ultrasonically. Thus is generated a synergistic effect: the ultrasonic vibration uses inertia force to break the cohesion and disperse the liquid, and the high-speed rotation generates centrifugal force to atomize the liquid.
