Patent number: 4529176Abstract: Ladles and the like into which hot metal is teemed are refractory lined to withstand the high-temperature effects of the hot metal. Prior to teeming of the hot metal into the ladle, the ladle is heated by applying a flame to the interior thereof, which flame is provided by a burner that directs the flame through a ladle cover plate having a substantially flat surface covered with heat-insulating refractory material, which surface is brought into sealing engagement with the ladle. This seal minimizes the amount of heat energy that escapes from the ladle to render the preheating operation more efficient. The rim of the ladle, which contacts in sealing engagement the heat-insulating refractory material of the ladle cover plate, causes wear and damage to the heat-insulating refractory material.Type: GrantFiled: October 24, 1983Date of Patent: July 16, 1985Assignee: Allegheny Ludlum Steel CorporationInventors: William M.

Patent number: 4433601Abstract: An electronic musical instrument by which a performer can provide a musical accompaniment in different musical styles. The performer selects a desired musical style and plays on a standard keyboard in order to express a desired harmony. The instrument translates the keyboard playing into a chord type and root that defines the harmony expressed by the performer. A processor generates parameter signals defining a segment of music including a plurality of accompaniment notes arranged in the selected musical style and related harmonically to the selected chord type and root. Output circuitry converts the parameter signals to sound so that a performer of limited skill or musical knowledge can play an appropriately-styled accompaniment to a melody written in any one of a variety of musical keys.Type: GrantFiled: September 30, 1981Date of Patent: February 28, 1984Assignee: Norlin Industries, Inc.Inventors: George R.
