Abstract

892,989. Automatic resistance control systems. ELEMELT Ltd. June 1, 1959 [May 30, 1958], No. 17260/58. Drawings to Specification. Class 38 (4). [Also in Group XI] The subject-matter of this Specification is substantially identical with that of Specification 892,990, but the claims relate to a method and apparatus (see Group XI) for producing a desired isothermal distribution in a glass stream in the vicinity of the outlet of a glassfeeding furnace by variation and comparison of current density in adjacent segmental regions of the outlet(s) between companion pairs of electrodes. Specification 835,201 also is referred to.
