Abstract: An ultrasound medical system includes an interstitial end effector. The interstitial end effector is interstitially insertable into patient tissue, includes at least one medical-treatment ultrasound transducer, and includes at least one end-effector-tissue-track ablation device. One method for ultrasonically treating a lesion in a patient includes the steps of obtaining the interstitial end effector and inserting it into the patient creating a tissue track which is surrounded by patient tissue and which ends at the distal end of the inserted interstitial end effector. Other steps include ultrasonically ablating the lesion using the at-least-one medical-treatment ultrasound transducer, using the at-least-one end-effector-tissue-track ablation device to ablate the patient tissue surrounding the tissue track along substantially the entire tissue track, and withdrawing the end effector from the patient.

Abstract: A system for temporal transmit apodization of an ultrasound transducer array. The system includes a waveform generator and an ultrasound transducer array having a plurality of transducer elements. Each of the transducer elements is driven by a signal generator that generates a periodic waveform. The duty cycle of each signal generator is determined by a predetermined setting of a duty cycle control. The duty cycle of each signal generator is calculated to achieve a desired beam profile of the transducer array, such as acoustic focusing for reducing the level of grating lobes and side lobes. Apodization is achieved by varying the effective amplitude at each array element by varying the duty cycle of the signal provided to each element.

Abstract: Corrosion sensors and methods of their use for monitoring corrosion of a material of interest. The corrosion sensors are adapted to be placed in the environment containing the material of interest during the period when corrosion is taking place. The corrosion sensors include a power source, a visual indicator and an electrode contained on a support. Changes in the electrical resistance of the electrode facilitate a display on the visual indicator including changes in color or brightness. Some corrosion sensors have power sources activated by directing a light source or other electromagnetic radiation source at the corrosion sensor. Some corrosion sensors have visual indicators containing thermochromic or electrochromic materials that are responsive to changes in voltage drop or current flow across the visual indicator. Some corrosion sensors have tracking devices to provide tracking information about the corrosion sensor.

Abstract: A peripheral ultrasound imaging system for connection to a personal computing device or a computer network which enables real time ultrasound imaging without additional modules and without the need to modify, augment or replace the existing central processing unit. The peripheral ultrasound imaging system includes an ultrasound probe, an electronic apparatus capable of sending and receiving signals to and from the ultrasound probe, a hardware link connecting the electronic apparatus to a personal computer or computer network, and a software program for controlling the ultrasound probe, the electronic apparatus, and the hardware link. The ultrasound probe is connected to the electronic apparatus and the electronic apparatus is in turn connected to a personal computing device or a computer network.

Abstract: A mixture suitable for the production of melt-processed high-temperature superconductors capable of producing a high levitation force. The mixture contains YBa.sub.2 Cu.sub.3 O.sub.7-x powder with a very low content of copper oxide, i.e. copper not bound in with the YBa.sub.2 Cu.sub.3 O.sub.7-x, and a very low carbon content. Also included are stabilizing (so-called "flux-pinning") additives. Also disclosed is a method or producing the mixture, as well as YBa.sub.2 Cu.sub.3 O.sub.7-x powder with suitable low free copper oxide and carbon contents, used to prepare the mixture.

Abstract: A package for facilitating the protection of metallic surfaces against corrosion and including a blend of corrosion inhibitor and surface-conditioning component such as a degreaser, descaler, and/or anti-static component in liquid state impregnated into a substrate such as a wipe for simultaneous and direct application to the surface of the article being protected. The corrosion inhibitor component is preferably an amine salt of carboxylic acid, triazole, an alkali metal salt of aldonic acid, or alkanolamine salts of fatty acids, an alkali metal or alkanolamine salt of aromatic sulfonic acid, or blends thereof. The substrate is preferably a wipe fabricated from a fabric such as soft cotton, but may also include other wipe materials such as woven or non-woven polyolefin fabric, or non-woven materials such as paper toweling.

Abstract: A method for treating residues of barium sulfide or strontium sulfide leaching with waste sulfuric acid and hydrochloric acid, which method significantly decreases the amount of residual material which must be disposed of.

Abstract: A process for working-up waste materials from barium sulfide or strontium sulfide leaching in which the amount of waste material to be disposed of is substantially decreased.
