Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
136 words
THE METHOD OF SEALING AGAINST INGRESS OF MOISTURE BETWEEN SUBSTANTIALLY MOISTURE-IMPERVIOUS HEAT-SEALABLE THERMOPLASTIC LAYERS A PLURALITY OF PROXIMATE ELECTRICALLY CONDUCTING FINE METAL WIRES, WHICH METHOD COMPRISES, PLACING THE PLURALITY OF SPACED AND PROXIMATE FINE METAL WIRES TO BE SEALED ADJACENT TO A LIGHT-TRANSMITTING HEATSEALABLE THERMOPLASTIC LAYER, HEATING SAID METAL WIRES AND ADJACENT THERMOPLASTIC LAYER TO A PREDETEMINED TEMPERATURE AND APPLYING SUFFICIENT PRESSURE THEREBETWEEN TO CAUSE SAID METAL WIRES SUBSTANTIALLY TO EMBED INTO SAID THERMOPLASTIC LAYER WITHOUT FRACTURING SAME, SANDWICHING SAID WIRE-EMBEDDED THERMOPLASTIC LAYER BETWEEN TWO ADDITIONAL LAYERS OF SIMILAR THERMOPLASTIC, AND APPLYING SUFFICIENT TEMPERATURE TO SAID ADDITIONAL THERMOPLASTIC LAYERS AND SAID WIRE-EMBEDDED THERMOPLASTIC LAYER ALONG WITH SUFFICIENT PRESSURE TO THE EXPOSED SURFACES OF SAID ADDITIONAL THERMOPLASTIC LAYERS TO EFFECT A SUBSTANTIALLY MOISTUREIMPERVIOUS HEAT SEAL BETWEEN SAID ADDITIONAL THERMOPLASTIC LAYERS AND THE WIRE-EMBEDDED THERMOPLASTIC LAYER SANDWICHED THEREBETWEEN.
Claim 2
Independent Claim
136 words
THE METHOD OF SEALING AGAINST INGRESS OF MOISTURE BETWEEN SUBSTANTIALLY MOISTURE-IMPERVIOUS HEAT-SEALABLE THERMOPLASTIC LAYERS A PLURALITY OF PROXIMATE ELECTRICALLY CONDUCTING FINE METAL WIRES, WHICH METHOD COMPRISES, PLACING THE PLURALITY OF SPACED AND PROXIMATE FINE METAL WIRES TO BE SEALED ADJACENT TO A LIGHT-TRANSMITTING HEATSEALABLE THERMOPLASTIC LAYER, HEATING SAID METAL WIRES AND ADJACENT THERMOPLASTIC LAYER TO A PREDETEMINED TEMPERATURE AND APPLYING SUFFICIENT PRESSURE THEREBETWEEN TO CAUSE SAID METAL WIRES SUBSTANTIALLY TO EMBED INTO SAID THERMOPLASTIC LAYER WITHOUT FRACTURING SAME, SANDWICHING SAID WIRE-EMBEDDED THERMOPLASTIC LAYER BETWEEN TWO ADDITIONAL LAYERS OF SIMILAR THERMOPLASTIC, AND APPLYING SUFFICIENT TEMPERATURE TO SAID ADDITIONAL THERMOPLASTIC LAYERS AND SAID WIRE-EMBEDDED THERMOPLASTIC LAYER ALONG WITH SUFFICIENT PRESSURE TO THE EXPOSED SURFACES OF SAID ADDITIONAL THERMOPLASTIC LAYERS TO EFFECT A SUBSTANTIALLY MOISTUREIMPERVIOUS HEAT SEAL BETWEEN SAID ADDITIONAL THERMOPLASTIC LAYERS AND THE WIRE-EMBEDDED THERMOPLASTIC LAYER SANDWICHED THEREBETWEEN.
Claim 3
Dependent Claim
186 words
AN ELECTROLUMINESCENT DEVICE COMPRISING SPACED ELECTRICALLY ISOLATED AND ELECTRICALLY CONDUCTING LAYERS, AT LEAST ONE OF WHICH IS LIGHT TRANSMITTING; A LAYER COMPRISING ELECTROLUMINESCENT PHOSPHOR INCLUDING BETWEEN SAID SPACE CONDUCTING LAYERS; SUBSTANTIALLY MOISTURE-IMPERVIOUS LIGHT-TRANSMITTING HEAT-SEALABLE THERMOPLASTIC ENCASING SAID CONDUCTING LAYERS; LEAD-IN CONDUCTORS FORMED OF A PLURALITY OF SPACED AND PROXIMATE FINE METALWIRES SEALED THROUGH SAID THERMOPLASTIC AND ELECTRICALLY CONNECTING TO SAID ELECTRICALLY CONDUCTING LAYERS; EACH OF SAID LEAD-IN CONDUCTORS HAVING BEEN SEALED THROUGH SAID THERMOPLASTIC BY THE METHOD WHICH COMPRISES: PLACING A PLURALITY OF SPACED AND PROXIMATE FINE METAL WIRES ADJACENT TO A LIGHTTRANSMITTING HEAT-SEALABLE THERMOPLASTIC LAYER, HEATING SAID METAL WIRES AND ADJACENT THERMOPLASTIC LAYER TO A PREDETERMINED TEMPERATURE AND APPLYING SUFFICIENT PRESSURE THEREBETWEEN TO CAUSE SADI METAL WIRES SUBSTANTIALLY TO EMBED INTO SAID THERMOPLASTIC LAYER WITHOUT FRACTURING SAME, SANDWICHING SAID WIRE-EMBEDDED THERMOPLASTIC LAYER BETWEEN TWO ADDITIONAL LAYERS OF SIMILAR THERMOPLASTIC, AND APPLYING SUFFICIENT TEMPERATURE TO SAID ADDITIONAL THERMOPLASTIC LAYERS AND SAID WIRE-EMBEDDED THERMOPLASTIC LAYER ALONG WITH SUFFICIENT PRESSURE TO THE EXPOSED SURFACES OF SAID ADDITIONAL THERMOPLASTIC LAYERS TO EFFECT A SUBSTANTIALLY MOISTURE-IMPERVIOUS HEAT SEAL BETWEEN SAID ADDITIONAL THERMOPLASTIC LAYERS AND THE WIRE-EMBEDDED THERMOPLASTIC LAYER SANDWICHED THEREBETWEEN.
Claim 4
