Abstract: A multi-furnace control system selectively delivers preselected percentages of available power to furnaces of the system, preferably designated as either a melt furnace or a hold furnace.  The power supply delivers power to both furnaces.  A capacitor station in parallel connection to the power supply and the furnaces is tuned to form a tank circuit therewith.  Switches control the selected power delivered to the furnaces respectively and control the delivery of a first portion of the power for holding molten product in the hold furnace as the master control.  A remaining portion of the power is then delivered for melting product in the melt furnace.  The capacitor station acts as a reactive tank for both furnaces.

Granted: 1999-11-30
Abstract: A spring clutch mechanism (5) for the operation of roller shades (1) and other rollable items. This clutch mechanism (5) is designed to release for raising the shade (1) so as to minimize effort. Whereas prior art clutch mechanisms for roller shades are intended not to slip, or to slip only to save themselves, in this case, lowering of the shade is accomplished by overriding the clutch, causing it to slip. The clutch (5) can be adapted easily to accommodate known shade (1) weights. The inventive design provides superior operating characteristics and, because the clutch (5) can be built with as few as two parts, much lower cost.
