  • DuPont SentryGlas® Plus polymer rings were built up around the receptor during fabrication and a solid disk of DuPont SentryGlas® Plus placed on the bottom surface, where the lips extended.
  • SentryGlas® Plus assembly was assembled with glass and a DuPont SentryGlas® Plus interlayer sheet, and laminated by vacuum bagging and applying pressure at elevated temperatures
  • Example 3 consists of a bolted glass stainless steel receptor, a first and a second glass ply bonded together by a thermoplastic interlayer of DuPont SentryGlas® Plus as described in Figure 3 and is a variation of Example 2 except that the stainless steel receptor passed through both plies of glass, the closed end of the receptor being flush with the exposed surface of the second glass ply. The internal surface of the receptor was threaded for the attachment means and the polymer-contacting surface knurled to promote adhesion.
  • Fabrication consists of punching a hole in the DuPont SentryGlas® Plus interlayer, assembling rings of SentryGlas® Plus around the receptor, assembling the interlayer, rings, receptor and glass and laminating by vacuum bagging and applying pressure at elevated temperatures sufficient to cause the polymer to flow.
  • Example 4 consists of a bolted glass stainless steel receptor, a first and a second glass ply bonded together by a thermoplastic interlayer of SentryGlas® Plus as described in Figure 4 and was a variation of Example 3 except that the receptor further comprised a lip that projects from the bottom portion of the closed end of the receptor essentially parallel the surface of the glass. The lip was bonded to the glass surface with a thin layer of DuPont SentryGlas® Plus. The internal surface of the receptor was threaded for the attachment means and the polymer-contacting surface knurled to promote adhesion.
  • Fabrication consisted of punching a hole in the DuPont SentryGlas® Plus interlayer, assembling rings of DuPont SentryGlas® Plus around the receptor including a larger outer diameter ring to seal the lip to the top surface of the glass, assembling the interlayer, rings, receptor and glass and laminating by vacuum bagging and applying pressure at elevated temperatures sufficiently hot to cause the polymer to flow.
  • Example 5 consists of a bolted glass stainless steel receptor, a first and a second glass ply bonded together by a thermoplastic interlayer of DuPont SentryGlas® Plus as described in Figure 5 and was a variation of Example 1 except that the receptor comprised of a countersunk geometry to allow flush mounting with one internal glass surface. The internal surface of the receptor was threaded for attachment means. The countersunk receptor wall was bonded to the countersunk glass hole with a thin layer of the DuPont SentryGlas® Plus interlayer. This was achieved by molding a thin cup washer of DuPont SentryGlas® Plus at elevated temperatures that conformed to the countersunk receptor profile. The countersunk stainless steel receptor, DuPont SentryGlas® Plus cup washer, DuPont SentryGlas® Plus interlayer and glass were assembled and laminated by vacuum bagging and applying pressure at elevated temperatures.
  • Example 6 consists of a bolted glass stainless steel receptor system, a first and a second glass ply bonded together by a thermoplastic interlayer of DuPont SentryGlas® Plus as described in Figure 7 and was a variation of Example 5 except that the receptor comprised a countersunk geometry to allow flush mounting with one external glass surface.
  • the shaft of the receptor was knurled to promote adhesion and continued through the laminate and until the open end is flush with the external surface of the other glass ply. Attachment of the threaded fastener was made to the open end of the receptor.
  • the system was assembled by first adhesively attaching the countersunk portion of the receptor to one glass ply using an epoxy adhesive.
  • Rings of DuPont SentryGlas® Plus polymer were built up around the cylindrical portion of the receptor. A hole was punched in the DuPont SentryGlas® Plus interlayer, and the glass, receptor, and polymer system assembled and laminated by vacuum bagging and applying pressure at elevated temperatures, sufficiently high to make the polymer flow.
  • Example 7 consisted of a bolted glass stainless steel receptor system, a first and a second glass ply bonded together by a thermoplastic interlayer of DuPont SentryGlas® Plus as described in Figure 8 and was a variation of Example 3 except that the receptor was a dual receptor that was open on each end to both exposed glass surfaces, and able to accept an attachment means from either glass surface.
  • the polymer-contacting surface of the receptor was knurled to enhance mechanical adhesion between steel and polymer.
  • the internal surface of the steel receptor was threaded for the attachment means.
  • Example 8 consists of a bolted glass stainless steel receptor system, a first and a second glass ply bonded together by a thermoplastic interlayer of DuPont SentryGlas® Plus as described in Figure 9 and was a variation of Example 7 except that the receptor in Figure 9 further comprised a lip that projected into the interlayer interspersed between the two glass plies.
  • the polymer-contacting surface of the receptor was knurled to enhance mechanical adhesion between steel and polymer.
  • the internal surface of the steel receptor was threaded for attachment means. Fabrication consists of punching a hole in the DuPont SentryGlas® Plus interlayer, assembling rings of DuPont SentryGlas® Plus around the receptor.
  • the DuPont SentryGlas® Plus rings contacting the internal lip are extended past the glass hole diameter out to the diameter of the internal receptor lip.
  • the diameter of the punched hole in the interlayer was matched to that of the internal receptor lip.
  • the DuPont SentryGlas® Plus interlayer, stainless steel receptor, DuPont SentryGlas® Plus rings and glass were assembled and laminated by vacuum bagging and applying pressure at elevated temperatures sufficient to cause the polymer to flow.
  • Example 9 consisted of a bolted glass poly(acetal) DuPont Delrin® receptor system, a first and a second glass ply bonded together by a thermoplastic interlayer of DuPont SentryGlas® Plus as described in Figure 10 where the receptor device was embedded within the laminate and bonded directly to the DuPont SentryGlas® Plus interlayer.
  • the receptor provided an internal solid surface for connection with a fastener device.
  • the interlayer-contacting surfaces of the DuPont Delrin® receptor was knurled to enhance mechanical adhesion between DuPont Delrin® and DuPont SentryGlas® Plus interlayer.
  • the internal surface of the DuPont Delrin® receptor was a straight hole for attachment means.
  • the system was assembled by first cutting a hole in the DuPont SentryGlas® Plus interlayer of diameter equal to the DuPont Delrin® receptor. Two thin disks of DuPont SentryGlas® Plus interlayer were placed on the large flat surfaces of the DuPont Delrin® receptor and assembled with the DuPont SentryGlas® Plus interlayer and glass. The assembly was laminated by vacuum bagging and applying pressure at elevated temperatures, sufficient to cause the polymer to flow.
