Abstract: An uncrosslinked hydrogel, its process of preparation as well as its uses as an article for medical and/or surgical purposes, e.g., tubes, filaments, films, joints, implants and the like, especially in ophthalmology are provided herein. The uncrosslinked hydrogel has a relatively high water content and is prepared from a liquid starting composition which comprises 2 to 50% by weight of a copolymer of acrylonitrile and an elefinically-unsaturated comonomer bearing anionic groups, which is either salified or unsalified. The molar ratio of acrylonitrile to comonomer is between 90:10 and 100:0. The liquid starting composition includes a suitable solvent and a suitable non-solvent for the copolymer, the non-solvent being an aqueous solution of a salt. The ratio of solvent to aqueous salt solution non-solvent is between 500:1 and 0.5:1 by weight. The hydrogel has a microporous structure, an ionic capacity between 0 and 500 mEq/kg of gel, a hydric content between 50 and 90% and has an aptitude for permanent deformation under stress, even at a temperature below 40°C.

Title: Methods and apparatus for laser sculpture of the cornea

Granted: 1994-01-04
Abstract: METHODS AND APPARATUS FOR LASER   SCULPTURE OF THE CORNEA                 ABSTRACT OF THE DISCLOSURE    In use of laser radiation to ablate corneal tissue, to achieve a sculptured change in curvature of the optically used region of the cornea, a variable magnification (zoom) lens is combined with different sized apertures of an indexible mask to develop a relatively smooth profile for the changed curvature. The zoom-lens settings are varied in the course of cornea exposure through each of the succession of mask apertures.  To do this, the range of zoom-lens magnification can always be less than 2:1, yet the zoom-lens system can effectively reduce to insigni-ficance the stepped profiling that is inherent in reliance only upon the indexed aperture technique. Also described are techniques to achieve compensation for delivered flux-density variation as a function of instantaneous zoom-lens setting, and programmable control of the area of delivered flux density in a manner to correct for parabolic or other fall-off in delivered beam intensity as a function of radius outward of the axis of beam delivery.

Inventor: CHEA RAMON CON WOO JR
IPC: H04M19/00
Filed: 1981-08-11
Abstract: The transverse and longitudinal termination impedances of a subscriber line interface circuit may be independently controlled. The equivalent termination impedance of a subscriber line/trunk appearing to the central office can be adusted upward or downward from a lower resistance value, with longitudnal balance being determined by the matching of feed resistors. The circuit is implementable as a monolithic integrated circuit having low power dissipation, improved power bandwidth requirements, and lower voltage breakdown requirements for integrated circuits; all resulting in an improved telephone line interface circuit. Voltage or current feedback to synthesize the proper ac transverse termination impedance from a known dc resistance, is utilized the feed resistors in a telephone line circuit. The transverse and the longitudinal termination impedance are determined by choice of feed resistance value. The independent control of transverse impedance is achieveable as a result of the feedback circuitry being nonresponsive to longitudinal signal.

Abstract: A high performance laminating coverlay, and bond ply adhesive material includes one or more epoxy components which inter-react with a high molecular weight polyester component through a two-stage reaction sequence. The first stage of the reaction sequence includes a reaction between an aziridine cure component and a polyester component. The second stage of the sequence involves a reaction between the aziridine/polyester component and the epoxy component(s).  The resulting adhesive material provides a flexible, fully cross linked adhesive material with good Z-axis stability and without the evolution of volatile by-products. This resulting adhesive material can be used in bonding polyimide films to etched circuit patterns to provide a high temperature resistant, solvent resistant, moisture resistant, insulating material with good flow properties under normal elecronic circuit processing and environmental conditions. The adhesive material can be used as a bond ply adhesive material for flexible base, hardboard, and multilayer electronic circuit material applications, as well as surface to surface bonding of other materials. In addition, the adhesive material, prior to the second reaction, is stable and has a long shelf life.
