  • Apparatus for spinning multicomponent hollow fibers
    Patent number: 5320512
    Abstract: The invention provides a spinnerette assembly for multicomponent hollow fibers of the sheath/core type in which the channel for supplying the sheath material is located at a distance from the extrusion orifice of the spinnerette of no more than one-half of the width of the extrusion orifice. The spinnerette ensures uniform supply of the sheath material to the hollow fiber.

  • Method for laser cutting metal plates
    Patent number: 5168143
    Abstract: A laser cutting method for complex capillaries wherein a multi-mode beam from a solid-state is reduced to predominantly a single mode and focused to a spot about 40 microns in diameter. The laser is focused about 0.2 to 0.3 mm above the work piece. The predominantly single mode is a TEMoo mode. By recutting the capillary slots with the laser, metal oxide particles condensed from the vapor phase and resolidified molten metal on the walls of the slots are removed.
