  • Patent number: 5614052
    Abstract: The present invention relates to a method of splicing a hollow gasket such that the final welded joint remains highly flexible and does not impair the fluid flow between the two spliced sections. The two gasket sections having identical multiple-chambered cross-sections are held in a splice mold by precision tooling and air drawn through small holes in the splice mold by a vacuum pump. Heat is applied to each end of the gasket sections and the ends are brought into contact with one another. As the ends cool, a welded joint is formed. The integrity of each individual chamber is maintained so that, when spliced, the two gaskets sections become one, with the chambers forming continuous channels. The continuous channels create a higher insulating quality than if the channels were blocked at the welded joints. Further, corners spliced in this manner remain as flexible as the adjoining gasket sections.

  • Patent number: 5353361
    Abstract: A method for assembling a light wave guide switch calls for a switch having two groups of front ends of light wave guides. Each group of front ends faces the other group of front ends and each group is disposed on opposite sides of a coupling plane running perpendicular to the longitudinal axes of the light wave guides. The switch also has centering devices that extend parallel to each other, without offset, from a first end of a base plate to a second end of the base plate. The centering devices secure a plurality of light wave guides each extending through the coupling plane when each of the wave guides forms a single component. The method includes the steps of coupling the first end of the base plate to a stationary part of the switch and coupling a second end of the base plate to a drivable part of the switch while the switch is in the given switching position.

  • Patent number: 5337384
    Abstract: A method for interconnecting first and second optical fiber bundles (FIG. 4 ), each bundle comprising a plurality of optical fibers, comprises the steps of accurately forming substantially identical matrix arrays of apertures in first and second thin securing plates (FIG. 1, 20, 17). The use of thin plates for the securing plate makes it possible to form apertures by masking and etching with great precision, but the plates themselves have little mechanical strength. The first and second plates are aligned (by balls 24), and a first support member (31), which is mechanically rugged, is simultaneously contacted to the first securing plate (17) and to a first alignment pin (27). The first support member (31) is bonded to the first securing plate while the first securing plate (17) is in alignment with the second securing plate (20).

  • Patent number: 5336351
    Abstract: A flexible pipe connector is disclosed for connecting to a hard plastic pipe. The flexible pipe connector, preferably made of polyethylene, has a tubing member which defines a cylindrical wall with inner and outer surfaces, the cylindrical wall having a male end which has a plurality of undercuts formed on the outer surface. The male end with the undercuts is inserted into the female end of a hard plastic pipe with a solvent weld glue applied at the inner surface thereof. The solvent weld glue liquifies the inner surface of the pipe's female end to form a liquified layer of hard plastic which is received in the male end's undercuts and then hardens into a reconfigured solid layer. In this manner, the flexible pipe connector, which is inert and normally cannot be attached with glue to a hard plastic pipe, can be sealably secured to a hard plastic pipe as the liquified layer solidifies within the undercuts to prevent separation of the pipe connector and the hard plastic pipe and to provide a seal therebetween.
