The invention, in one embodiment, is directed to a catheter for site-specific delivery of a therapeutic agent to a blood vessel of a patient. The catheter further includes an elongated shaft having at least one inner lumen, a distal end and a proximal end and proximal and distal vessel-conforming balloons where each is separately positionable and inflatable, and when inflated, substantially restricts blood flow in the vessel and creates a treatment window of a defined but variable length for delivery of the therapeutic agent. The catheter optionally includes at least one marker band adjacent to the proximal balloon and at least one marker band adjacent to the distal balloon. At least one lateral aperture positioned in the window is in fluid communication with a drug delivery conduit located within either the inner shaft or the outer shaft to provide a homogeneous concentration of the therapeutic agent to the window.

The illustrative embodiment of the invention is a tunable nanomechanical near-field grating capable of varying the intensity of a diffraction mode of an optical output signal. In accordance with the illustrative embodiment, the tunable nanomechanical near-field grating comprises a first and second sub-grating, each sub-grating having line-elements with width and thickness less than the operating wavelength of light with which the grating interacts. A plurality of lateral apertures is formed by the two sub-gratings, each aperture comprising the space between one line-element of the first sub-grating and at least one line-element of the second sub-grating. One of the first or second sub-gratings is capable of motion such that at least one of aperture width and aperture depth changes, causing a perturbation to the near-field intensity distribution of the tunable nanomechanical near-field grating and a corresponding change to the far-field emission of the tunable nanomechanical near-field grating.

The invention discloses an eccentric type tamping pickax with self-lubrication function, belonging to mechanical field of railway maintenance, which is characterized in that: a central hole and a lateral aperture are processed on an eccentric shaft which is provided with an oil suction nozzle at the lower end; an oil seal arranged at the upper end of the rod shell enables the rod shell form a confined space; a partial pressure gland bush is arranged in a hole at the lower end of the rod shell; the bearing and the partial pressure gland bush enable the confined space to form an upper and a lower parts with lubrication oil arranged at the lower part. When the momentum of a gasoline engine passes through a clutch and a flexible shaft drives an eccentric shaft to rotate to produce vibration, the eccentric part of the eccentric shaft drives the air flow at high speed, thereby enabling the pressure at the upper part of the confined space smaller than the pressure at the lower part; under the action of pressure difference, the lubricating oil flows to the upper part of the bearing through the central hole and the lateral aperture and flows back to the lower end through the bearing under the gravity action, thereby forming a circulation; on one hand, the flowing of the lubrication oil lubricates the bearing and takes away the hot energy produced by high-speed rotation of the bearing on the other hand, thereby prolonging service life of the bearing.

A method and apparatus for printed circuit board pads with registering feature for component leads. A U-shaped metalized pad is disposed on a printed circuit board for soldering to a component lead. Solder is disposed on the pad and heated to a molten state so that surface tension and wetting effects form the molten solder into a solder mound having a U-shaped lateral cross section conforming to the U-shaped metalized pad. The solder mound has a first arm and a second arm, and a lateral aperture extending therebetween for receiving an extremity of the component lead, and registering the extremity of the component lead with respect to the pad.

A biopsy system comprises an introducer, a biopsy device having a needle, and a marker applier. The introducer may include a closed distal tip, a lateral aperture, a proximally facing interior wall, and a ramp that guides the closed distal end of a marker applier up and into abutment with the wall as the applier is fed into the introducer. The needle of the biopsy device includes a blunt distal end and features providing clearance for the ramp as the blunt distal end is brought into abutment with the wall when the needle is fed into the introducer. The introducer may alternatively include an open distal end having resiliently biased leaves that bear against an inserted biopsy device needle. In some other versions, a fin projects laterally from the closed distal end of a marker applier, spacing the distal end away from a sidewall region of the introducer cannula.

A method for closing a box (1) by folding a lateral closing flap (5) extending from an upper edge (6) of a lateral aperture (7) of the box (1) and having at least one foldable edge (8), while the box (1) is being moved along a packaging line (L) in a forward movement direction (W), includes the steps of folding the lateral flap (5) until a connection line (9) of the foldable edge (8) touches stop means (15), then folding the foldable edge (8) on the striking means (15) and toward the lateral aperture (7) of the box (1), so that an outer edge (8a) of the foldable edge (8) interacts with contrast means (17), which keep elastically the edge (8) in a position raised with respect to a bottom wall (1a) of the box (1), and lastly introducing the edge (8) into the box (1). A device for carrying out the methods has folding means (14) for folding the said lateral flap. Then first pusher means (16) fold the foldable edge (8) toward the box (1) against contrast means (17), while second pusher means (18) are disposed crosswise and in alignment the said contrast means (17) to strike the lateral flap (5) and insert the lateral flap into the box (1).

The striking watch (1) includes a watch case, which is formed of a middle part (4) and a back cover (5) removably secured to the middle part, and a crystal (2) that closes the case in a sealed manner. A watch movement (20) is held inside the watch case on a plate (14). The watch movement is provided with a striking mechanism able to be actuated at determined times to produce a sound. At least one acoustic membrane (10) is arranged between the back cover (5) which includes at least one lateral aperture (6) and the plate (14) of the watch movement. This acoustic membrane is made of amorphous metal or metallic glass to radiate the sound produced by the striking mechanism towards the exterior of the case.
