  • Method for precisely perforating an opening in footwear
    Patent number: 5924345
    Abstract: A method for precisely perforating an opening in footwear by positioning the footwear on a foot form with the outsole facing upward, supporting the vamp area of the footwear by a V-shaped support, clamping the rear section of the footwear to stabilize the footwear and moving the footwear upwardly against the die under pressure so that an opening is perforated in the heel area of the footwear. The apparatus includes a shuttle member on which the foot form, the V-shaped support and the clamp are carried. The clamp is activated when the shuttle is moved to contact a limit switch. The footwear is caused to be moved upwardly against the die under pressure upon the operator activating a switch.

  • Optical fiber SC type connector assembly with partly pre-assembled components
    Patent number: 5287425
    Abstract: A SC type connector assembly includes a square hollow front housing (10) and a tubular rear housing (26) interconnected to each, other by means of protrusions (28) of the rear housing (26) captured by the corresponding aperture (18) of the front housing (10). An alignment ferrule (36) is positioned within the interior of the front housing (10) and the rear housing (26) with a spring (42) providing a biased force against the alignment ferrule (36) and the rear housing (26). The rear end of the alignment ferrule (36) extends a distance out of the rear end of the rear housing (26). An auxiliary spacer (50) abuts against the rear end of the rear housing (26). A crimping ferrule (44) is to circumferentially cover the rear portion of the rear housing (26) and most of the spacer (50) for sandwiching the strength members (70) and the jacket (72) of the optical fiber cable (74) therebetween. A boot (58) circumferentially covers the crimping ferrule (44).

  • Axially-graded index-based couplers
    Patent number: 5815318
    Abstract: An optical coupler is provided that comprises one lens component, comprising at least one axially-graded index of refraction element. When the optical coupler component includes one axially-graded index of refraction element, a homogeneous "boot" element is cemented on entrance surface to provide plano-plano coupling. When the optical coupler includes two or more axially-graded index of refraction elements, both entrance and exit surfaces are planar. The optical coupler component may be sized to provide focusing at its exit surface. The axially graded index-based couplers of the present invention comprise a single component, thereby reducing the number of components and the concomitant complexity of the optical system. Further, many of these couplers can be fabricated with plano-plano entrance-exit surfaces, thereby obviating the need for forming curved focusing surfaces and thus avoiding the introduction of air spaces.
