Title: Ultrasound imaging system and method for implantable and invasive devices
Inventor: BRENNEN KENNETH R
IPC: A61N1/375
Filed: 2001-07-02
Abstract: An improved system and method to provide visualization of implantable leads, catheters, or other implantable devices is disclosed. According to the invention, an unmodified guiding device such as a stylet or guidewire (5) is frictionally coupled to a vibration device (7).

These waves are detected by an imaging device (50, 52), which then generates a Doppler image of the implantable device. According to one aspect of the invention, the vibration device includes a piezoelectric actuator. According to another aspect of the invention, the frequency of the waves that are transferred by the vibration device is selectable.

Abstract: The present invention relates to an improvement in filtering apparatus including a filter device externally hitched on a wall surface of a aquarium for breeding aquarium fishes. In the outside-type filtering apparatus including a filter device (F) and detachably supported in an externally hitched manner on a wall surface of a aquarium (V), and a water pump (P) for pumping water stored in the aquarium (V), the filter device (F) is formed so that the water pumped from the water pump (P) is divided into a first flow which is returned into the aquarium (V) as remaining unfiltered, and a second flow which is filtered through a filter element and then returned into the aquarium (V) in dependence on a siphon effect. Thus, it is possible to enhance the filtering action provided by the filter element of the filter device and the organically purifying function provided by aerobic microorganisms, and to suppress the clogging of the filter element to reduce the maintenance frequency of the filter element.

The invention further relates to the aforementioned supported catalysts. The method and catalysts according to the invention are especially suitable for hydrating polyfunctional compounds such as hydroxycarbonyl compounds and aromatic amines.

Title: Ram memory based on nanotechnology, capable, among other things, of replacing the hard disk in computers
Inventor: GADASSI HAIM
IPC: G11C13/02
Filed: 2001-12-11
Abstract: As the Internet becomes faster and faster, with more and more demanding applications, and after the problems of faster routing and faster optic fibers are solved, the next main bottleneck will be the speed of the servers, and more specifically the speed (or rather the lack of it) of the hard-disks.  Therefore, finding new revolutionary ways of making faster and larger hard-disks and/or larger RAM in the computer itself can help boost the computer and Internet world much faster into the future. The present invention tries to solve the problem of making much faster and much larger preferably non-volatile RAM by Using preferably 3-dimensional addressable nano memory matrices (FIG.3) instead of 2-dimensional, so that for example if instead of a 10x10 cm flat surface we have for example a 6x6x1 cm or 3x3x2 cm cube, we can get millions of Terabits, which are millions of times larger than current hard disks. So this can be used for example as computer RAM memory, as a hard-disk, or as a removable cartridge that conveniently fits in the pocket. Many variations are discussed, including memory cells(FIG. 4) that have more than two states each, and intermediate systems wherein normal lithographically produced cells are each coupled to one or more nano-chips within them.

Abstract: A hand-held device (1) for dispensing a metered quantity of a substance such as a pharmaceuticals, medicinal, or therapeutic substance, and applying that substance to the skin of a host animal. The device (1) includes a hollow body (2) that can be grasped by the hand of a user, and a substance capsule (4) mounted within that body. The capsule (4) includes a container (5) for the substance, and a nozzle (10) through which a quantity of the substance is dispensed, possibly in the form of a spray. The device (1) also includes actuator means (6,9) connected to the interior of the substance container (5) and operable to cause a metered quantity of the substance to be dispensed through the nozzle (1). The actuator means (6,9) may include a manually operable pump (6), or it may include a valve that is selectively operable to prevent or permit pressurized contents of the container (5) escaping in the form of an aerosol. In the former case, the pump (6) may be operated through an actuator button (9), and in the later case the valve may be opened through operation of an actuator button (9). The device (1) also includes means for preventing or minimising unintentional loss of the stored substance. In one form, that means includes a closure member (2) that is operable to close or open the nozzle outlet. In another form it includes an absorption pad (31) onto which an initial quantity of the substance is deposited, and which is thereafter removed to permit normal operation of the device (1). If a closure member (20) is used, means may be provided to apply a force to that member so as to ensure effective closure of the nozzle outlet. Substance emerging from the nozzle (10) is received within a shroud (13) for confining the dispensed substance to a designated target area, and which may also function to position the nozzle (1) at a suitable distance from the target area.

Abstract: An air turbine apparatus (10) for use with a combustion engine either as a muffler or as an air intake device is comprised of a housing (12) defining an expansion chamber (20) and an airfoil (50) positioned within the housing (12).  The airfoil (50) includes a central aperture (52) extending longitudinally there through that is in fluid communication with both the inlet (18) and the outlet (16) of the housing (12). The airfoil (50) is configured to allow gases flowing through the inlet (18) to flow between the outer edge of the airfoil (50) and the housing (12) and through the aperture (52) of the airfoil (50).  In addition, the air travelling through the housing (12) is caused to spin as it travels through the housing (12). This rotational flow increased the rate of flow of gases through the air turbine device (10). An induction tube (22) is provided between the airfoil (50) and the outlet (16) of the housing (12) to encourage turbulent flow of gases without restricting flow to produce a muffling effect and thus a dampening of noise from the combustion engine.

Inventor: DIMONIE VICTORIA L
IPC: C08J9/32
Filed: 2002-05-24
Abstract: Hollow thermoexpandable particles or microspheres are provided that contain hydrocarbon blowing agents and have a shell polymer that can be softened at the onset of the expansion temperature and solidified at a higher temperature (thermoset) in an expanded state. Preferably, the microspheres have a shell of thermally expandable and thermally crosslinkable polymer and a hollow interior that contains a hydrocarbon liquid that boils at a temperature below the heat activated crosslinking temperature of the polymer shell. The crosslinking of the shell polymer during or after expansion, which is heat activated at an elevated temperature, can solidify the shell polymer and, then, maintain the expanded volume of the microspheres. The thermoexpandable thermoset polymer particles are useful in insulation, packaging, for making foam materials such as polyurethane or polyisocyanurate rigid foams. The invented thermoset microspheres can substantially improve the close cell percentage and compressive strength of the foam materials and make the foam manufacturing less hazardous.
