  • Apparatus for exterior arterial ablation
    Patent number: 6869429
    Abstract: A method and apparatus for reducing the thickness of arterial walls is disclosed. Ablation of the exterior layer of the arterial walls is performed using mechanical or laser ablation techniques. Surveying is preferably carried out during the procedure to ensure optimal ablation. The ablation reduces the effective thickness of the arterial walls and increases flexibility so that the walls distend under normal blood pressure, thereby improving blood flow. Advantageously, the procedure is carried out without invasion of the blood vessel lumen and without damage to the inner layer of the artery wall.

  • Method for controlling the shed in a loom with fluidic weft insertion
    Patent number: 6863091
    Abstract: The shed of a fluidic weaving loom is not changed simultaneously for all warp threads, but rather continuously starting at the weft entrance and continuing helically, so to speak, to the exit of the warp shed. This sequential shed closure takes place with a so-called domino effect along a helical line curved in space, whereby additional time is gained for stretching the inserted weft thread and temporarily stopping the shed formation or shedding is avoided.

  • Central vacuum cleaning system motor control circuit mounting post, mounting configuration, and mounting methods
    Patent number: 6856113
    Abstract: A central vacuum cleaning system has a motor in a motor housing in a canister with a receptacle. In the motor housing is a motor control circuit with a printed circuit board. The motor control circuit is mounted to the motor housing using a mounting post having a light guide. The mounting post receives light from a light source on the printed circuit board and guides the light through the mounting post to outside the motor housing. The mounting post can guide the light through structural or non-structural elements. The light provides illuminated information messages to a user. The mounting post has a low voltage connection section for receiving low voltage conductors from outside the motor housing. As the motor control circuit is within the motor housing, the motor housing is a motor control housing. The motor control housing can be separate from the motor housing.

  • Method for controlling the shed in a loom with mechanical weft insertion
    Patent number: 6834681
    Abstract: In a loom with a mechanical weft insertion the motion of each individual warp thread on its way from an uppermost position to a lowermost position and vice verse is controlled individually by a jacquard in such a way, that the motion profile includes a shed stopping in a weft entrance section and simultaneously in a weft exit section of a weaving width of the loom. Shed stopping is avoided in an intermediate section between the weft entrance and exit sections of the weaving width of a loom thereby providing sufficient time for the rapiers or grippers to be withdrawn from the shed without damaging the warp threads.
