    Abstract: A family of dielectric glasses having properties such that, when heat is applied to seal the dielectric glasses, there is no crazing in a MgO overcoat. These dielectric glasses have such viscosity properties as not to craze a MgO overcoat at a temperature of about 480*C corresponding approximately to log viscosity of 10.3 poises and yet fire into good dielectric films at about 610*C. The glass has substantially the following constitutents:

    Abstract: An improved method of edge-plating large coupled film memories is disclosed. The improvement resides in the edge-plating step in which an etched coupled film device is immersed in a nickel-iron or nickel-iron-copper plating bath comprising K2CO3 0.0 moles to 0.00362 moles; NaK tartrate 0.0248 moles to 0.0532 moles; NiCl2. 6H2O 0.084 moles to 0.211 moles; FeSO4.7H2O 0.0054 moles to 0.0211 moles; CuSO4.5H2O 0.0006 moles to 0.002 moles; saccharin as a 10 percent solution 0.10 g. to 0.06 g.; H2O to make 1 liter; and having a pH of from 3.9 to 5.8. The magnetic edge film is plated by a pulse plating technique in which the current pulses have a duration of about 6 seconds, the solution is stirred for about 4 seconds and the pulse remains off for about 24 seconds before starting the next current pulse.
