Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
104 words
A PROCESS FOR PRODUCING A PRE-FORM OF LOW-MELTING GLASS WHICH COMPRISES IMMERSING CHUNKS OF LOW-MELTING GLASS HAVING A MELTING POINT OF ABOUT 250* TO 400*C. IN A LIQUEFIED INERT GAS UNTIL APPROXIMATELY THERMAL EQUILIBRIUM IS ATTAINED, THE CHUNKS BEING COOLED BY EVAPORTION OF THE LIQUEFIED GAS, SEPARATING THE GLASS CHUNKS FROM THE LIQUEFIED GAS, GRINDING THE CHUNKS TOFROM PARTICLES OF DESIRED MESH SIZE, COLD PRESSING THE LOW-MELTING GLASS POWDER SO OBTAINED TO PREDETERMINED CONFIGURATION AND THEN HEATING THE PRESSED GAS TO TEMPERATURE BETWEEN THE SOFTENING POINT OF THE GLASS UP TO 100*C. THEREABOVE UNTIL THE GLASS PARTICLES COHERE TO PRODUCE A PHYSICALLY STRONG STRUCTURE.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
72 words
A PROCESS FOR APPLYING A PROTECTIVE COATING TO AN ELECTRONIC DEVICE WHICH COMPRISES PLACING A PRE-FORM FO PREDETERMINED CONFIGURATION COMPOSED OF LOW-MELTING GLASS HAVING A MELTING POINT OF ABOUT 250* TO 400*C. OVER THE DIVICE TO BE PROTECTED AND THEN HEATING DEVICE TO TEMPERATURE ABOUT 100* TO 200*C. ABOVE THE SOFTENING POINT OF THE GLASS, THEREBY EFFECTING SLOWFLOWING OF THE GLASS OVER THE DEVICE SO THAT IT BECOMES ENCAPSULATED IN THE GLASS.
