Title: Precooled cryogenic ablation system
Inventor: LI HONG
IPC: F25B9/02
Filed: 2000-06-23
Abstract: A method and apparatus for using a secondary refrigerant (14) to precool and liquefy a primary refrigerant (12), then vaporizing and expanding the primary refrigerant to cool a cold tip (20) of a cryosurgical instrument for ablation of biological tissue, such as cardiovascular tissue, in particular endocardiac tissue and tissue inside a cardiac blood vessel. The secondary refrigerant (14) has a critical temperature above the critical temperature of the primary refrigerant (12), and a cooling temperature below the critical temperature of the primary refrigerant, thereby facilitating the use of of the precooling step to provide liquid primary refrigerant in an operating room environment in which the primary refrigerant could not otherwise be provided in the liquid phase.

Abstract: An optical fiber with a core of non-circular cross-section is realized by a method including the steps of creating a void having the desired cross-section in a preform housing and filling the void with an optical material. This structure is then collapsed to solidify it and drawn to desired dimensions.  The optical material may be rods, soot or ground material. An active region which may be provided in the core does not necessarily have a different refractive index than that of immediately adjacent material. The active region of the drawn fiber may only support oscillation in the fundamental transverse mode. The fiber drawn by the method disclosed may be used to convert multi-mode pump light into single mode light, e.g., for pumping a single mode amplifier.

Title: Container closure system
Inventor: PITASSI JAMES L
IPC: B65D41/17
Filed: 2000-09-13
Abstract: A container closure comprising a cap (2, 20) having a skirt (4) of substantially rectangular cross-section. Disposed m a central location of each internal surface (5) of the skirt are substantially coplanar nm-engaging members (96, 26). The container (3) has a neck portion (12) terminating in an outer peripheral nm (8) surrounding an oval-shaped opening (7) in one end of the container.   Cap-engaging portions (9) on the outer portion of the peripheral rim engage with the rim-engaging members disposed on the skirt internal surface when the cap is m a closed position over the container opening The rim-engaging members can be in the form of small ridges (60) or grooves (26) and can engage with cap-engaging portions formed by small ribs (9). Alternatively, when in the form of small ridges, rim-engaging members can engage with cap-engaging portions in the form of a small edge extension around the outer portion of the peripheral rim. The cap may be placed into a closed position on the container by aligning the edge of the skirt with a similarly configured edge of the container body and "snapping"  the rim-engaging members on the skirt into an engaged relationship with the cap-engaging portions on the peripheral nm. Twisting the cap slightly with respect to a vertical axis of the container disengages the rim-engaging members and the cap-engaging portions to release the cap to an open position for removal from the container.

IPC: F03B17/06
Filed: 2000-08-08
Abstract: The invention concerns a marine current power installation. This involves not just a known tidal power installation which makes use of the energy of tidal ebb and flow, but a power installation which takes energy from marine currents which constantly occur over all oceans.      The invention proposes designing a marine current power installation which takes kinetic energy of flow from the marine current and converts the taken energy into electrical energy. In that case the marine current water power installation according to the invention is used below the water level, for example more than 50 m below the water level, and can make a relatively large amount of power available even when the flow speed of the marine current is relatively low, for example in the region of 1.5 m/sec or less. That is achieved in that the water power installation has a water wheel or a rotor (turbine or propeller) which is of a diameter of for example 10 m or more, preferably between 30 m and 120 m.

IPC: E04G17/14

Abstract: A chamfer for securing precast concrete wall panel forms that are used in tilt-up construction. The chamfer includes an elongate base portion and at least one chamfer portion coextensive with the lengthwise direction of the elongate base portion. The base portion defines a substantially horizontal base plane. The chamfer portion includes a first leg disposed upstanding relative to the base portion, and a second leg portion angularly disposed relative the first leg. The second leg further includes at least one flexible edge that projects beyond at least the base plane or the plane defined by the lengthwise direction extension of the first leg.  Depending on which part of the second leg the edge is cantilevered from, it forms a sealed relationship between the chamfer and a casting surface, the chamfer and a plank used as part of the wall form, or both. The application of weight, usually due to the addition of a plank, causes the base portion of the chamfer to flex, which in turn causes the flexible edges disposed on the chamfer outside the elastic curve defined by the flexed base portion to splay, and edges disposed on the chamfer inside the elastic curve to pinch, thereby effecting a seal to minimize or eliminate leakage associated with the poured concrete.

Title: Apparatus and method for treating an ocular disorder
Inventor: GHARIB MORTEZA
IPC: A61M5/00
Filed: 2001-03-08
Abstract: Surgical methods and related medical devices for treating glaucoma are disclosed. The method comprises trabecular bypass surgery, which involve bypassing diseased trabecular meshwork with the use of a seton implant. The seton implant is used to prevent a healing process known as filling in, which has a tendency to close surgically created openings in the trabecular meshwork. The surgical method and novel implant are addressed to the trabecular meshwork, which is a major site of resistance to outflow in glaucoma. In addition to bypassing the diseased trabecular meshwork at the level of the trabecular meshwork, existing outflow pathways are also used or restored. The seton implant is positioned through the trabecular meshwork so that an inlet end of the seton implant is exposed to the anterior chamber of the eye and an outlet end is positioned into fluid collection channels at about an exterior surface of the trabecular meshwork or up to the level of acqueous veins.
