Title: System and method for delivering agents into targeted tissue of a living being
Inventor: EVANS DOUGLAS G
IPC: A61B17/22
Filed: 2000-07-28
Abstract: The systems basically comprise a delivery system for accessing the targeted tissue within the living being and introduction of at least one agent at select locations into the myocardium and other select tissues. The delivery systems are arranged to access the tissues of the heart. One or more of the systems can be utilized during transluminal, transthoracic and direct surgical access procedures. Where appropriate, for example in the case of intraventricular access, portions of the system are steerable to properly orient the device. The instruments may pierce the heart tissue and create channels extending from the endocardium, the epicardium, or the cardiac vessels. When tissue penetration is utilized, the device may include a feature to control the depth of penetration. To minimize bleeding through the channels the device can dilate small initial punctures that later contract down after device removal.  When the formation of channels is required, this can be achieved, by way of example, with a rotary-tipped device, pressurized fluid jet devices, vibratory instruments and piercing needle-like tip devices. The system may utilize some form of mechanical action or application of energy (e.g. electrical, sonic, thermal, optical, pressurized fluid, radio frequency (RF), nuclear) in the process. The mechanical action or energy application may affect the surrounding tissues at a distance from the device. The agent delivered to the tissue may include one or more of pharmaceuticals, biologically active agents, radiopaque materials, etc.

Title: Method for making a beam from a metal sheet
Inventor: JAEKEL FEDERICO G
IPC: B21B1/08
Filed: 2000-10-18
Abstract: A method for making a beam from a metal sheet (10), includes the steps of providing a metal sheet having opposite first and second side edges (12, 14) extending longitudinally along opposing sides of the metal sheet, and a first and a second generally parallel opposing face surfaces (16, 18) provided between the first and second edges. The first and second generally parallel opposing faces define a thickness of the metal sheet therebetween. The thickness of the metal sheet is split at one of the first and second side edges to form first and second integral flanges (28, 30, 32, 34) from a portion of the metal sheet such that inner ends of the first and second flanges remain integrally connected with an unsplit portion (44) of the metal sheet. The first and second flanges are then bent so as to provide the metal sheet with a tubular portion extending along one side of and integrally formed with the unsplit portion. The first and second flanges are then fixed against movement relative to one another.

Title: Treatment of electric arc furnace dust to resist acid and alkaline leaching of heavy metals
Inventor: SMITH CHARLES L
IPC: F27D99/00
Filed: 2002-05-03
Abstract: A supplemental agent for a hazardous waste composition containing electric arc furnace dust (EAFD) includes potassium magnesium sulfate or a magnesium salt such as magnesium sulfate or magnesium chloride. The supplemental agent when mixed with EAFD and water, along with lime either lime inherent within the EAFD or added lime, reduces the leaching of heavy metals from the waste composition over a wide range of leaching conditions, including both acidic, neutral, and alkaline environments. The method for reducing the concentration of heavy metals in a leachate from the EAFD involves forming a mixture of EAFD, water, the supplemental agent, and, optionally, ferrous sulfate, along with lime, then permitting the mixture to react.

Abstract: Invention problem To generate a transient high voltage, which continuously follows the zero crossing of the high-current in the test circuit-breaker, on a test circuit-breaker arranged initially in a high-current circuit, by means of a high-voltage oscillating circuit and by transferring oscillating current with constant parameters from an auxiliary circuit-breaker in the high-current circuit as sequence current to the test circuit-breaker, which is consequently located in the high-voltage oscillating circuit.        Solution to the problem A high-voltage oscillating circuit (I), connected in parallel with the auxiliary circuit-breaker (B a) by firing the switching spark gap (SG hv) and the oscillating current (i hv) superimposed on the high-current (i hc) with opposite polarity just before the high-current zero crossing. The spark gap (SG hc) is fired at the artificial current zero, causing: short-circuiting of the high-current source (G), series connection of the high-voltage oscillating circuit with the test circuit-breaker (B t), oscillating current from the auxiliary circuit-breaker is transferred with constant parameters to the test circuit-breaker there-in following the eliminated high current. Transient high voltage follows the zero crossing of the synthetic current continuously.        Rationalization effects Transformer economized in the high-current circuit - high-current switching spark gap used for two purposes - very high rated voltages in the test circuit-breaker:  a second high-voltage oscillating circuit (II) increases the transient voltage rationally -natural short-circuit current, natural transient voltage: proven identical simulation, no need for expensive comparative tests.

Title: Balancing personal vehicle
Inventor: FIELD J DOUGLAS
IPC: A61G5/10
Filed: 2000-12-08
Abstract: A transportation vehicle (100) for transporting an individual over ground having a surface that may be irregular. The vehicle has a support platform (112) for supporting the subject and the support platform is coupled to a ground-contacting module at a pivot (118). While the ground-contacting modul e may be statically stable, balance of the support platform with respect to th e ground-contacting module (104) is maintained by motion of the ground- contacting module in response to leaning of the support platform. A motorize d drive coupled to the ground-contacting module causes locomotion of the vehic le and the subject therewith over the surface, while a control loop, in which t he motorized drive is included, dynamically enhances stability in the fore-aft plane by operation of the motorized drive in connection with the ground- contacting module. In the event of failure of the control loop, the pivot connection of the support platform to the ground-contacting module may be locked, thereby ensuring stability of the static assembly.

Title: High-low pressure hermetic compressor
Inventor: FRY EMANUEL D
IPC: F04B39/02
Filed: 1998-11-06
Abstract: A compressor assembly includes a compressor mechanism mounted within a hermetically sealed housing. The housing is effectively divided into a low pressure area at a relatively low temperature and a high pressure area at a relatively high temperature. A motor and a lubrication system are contained within the low pressure area and the discharge side of the compressor mechanism is disposed in the high pressure area. A cylinder block effectively separates the high and low pressure areas of the compressor. The lubrication system includes an axial passage for communication oil from a sump to various compressor components, including rotational bearings. A seal cap is disposed at the end of the crankshaft that extends into the high pressure area and in combination with the cylinder block defines an oil discharge chamber at low pressure and isolated from the high pressure area. A  second vent passage formed in the upper end portion of the crankshaft provides a communication path between a suction cavity formed in the compressor mechanism and the oil discharge chamber within the seal cup. A pressure drop caused by the reciprocating action of the pistons in the compressor mechanism occurs at the oil discharge area formed in the seal cup thereby assisting the oil pump in drawing oil through the oil passage in the crankshaft. An acoustic insulator is provided intermediate the compressor mechanism and a mounting flange to isolate and reduce vibration and noise which occurs during compressor operation.
