Claim 4

A glass forming system comprising at least one individual section including a plurality of separately operable elements; feeder means for periodically applying molten glass to each said section, and respective section computer means, one associated with each said section, for generating signals to said section to effect cyclical operation of said elements in synchronism with said feeder means, to form rigid glassware from said applied molten glass, said section computer comprising multiplexer means, including a plurality of output ports and responsive to address signals indicative of said output ports and data input signals applied thereto, for generating MUX output signals indicative of said data signals, at the output port indicated by said address signals; a plurality of driver means, at least one associated with each of said elements, for generating a signal to effect operation of said element in accordance with a driver data signal applied thereto, each said driver means being coupled to a respective corresponding multiplexer output port and said MUX output signal being applied thereto as said driver data signal; a run table memory, including a plurality of sequenced locations and having at least one location corresponding to each operation in said cyclical operation of said elements; means for loading each of said run table memory locations with indicia of the relative point in said cyclical operation the corresponding operation as to be effected; indicia of the multiplexer output port corresponding to the driver means associated with the element on which said corresponding operation is to be effected, and indicia of the data signals for effecting said corresponding operation; means for generating a machine cycle signal indicative of increments of advancement of said section through said cyclical operation of elements; means, responsive to said machine cycle signal, for generating a machine cycle count indicative of the instaneous cyclical position of said seciton; and means, responsive to said machine cycle signal, and said machine cycle count, for selectively accessing said run table memory locations, comparing said corresponding operation relative cycle point indicia of said accessed run table locations to said machine cycle count, and, responsive to a favorable comparison, generating signals indicative of said multiplexer output port indicia and data signal indicia, to said multiplexer means a said address input signal and data input signal, respectively.

Claim 5

The system of claim 2 wherein said means for loading comprises: a central console, associated with a plurality of glass forming shops, each said shop including at least one said individual section and associated section computer means; said central console including a stored library of job histories, each said job history including, with respect to each operation in a cyclical operation to form an associated type of ware, indicia of the relative point of in said cyclical operation the operation is to be effected, indicia of the multiplexer output port associated with the element on which the operation is effected, and indicia of the data symbols for effecting the operation; and means for selectively communicating a designated job history to a specified section computer means run table memory.

Claim 6

The system of claim 3 wherein said means for selectively communicating includes a respective shop computer means, associated with each glass forming shop, for selectively receiving job history communications from said central console to respective designated section computer means in said shop, and selectively generating signals indicative of said received job histories to load the designated section computer run memory table.

Claim 7

The system of claim 4 wherein said shop computer means includes: a non-volatile memory for storing indicia of said received job histories; a non-volatile section status word for storing indicia of whether the designated section computer means run tables have been loaded with the stored job history indicia in said non-volatile memory; and means, responsive to said section status word, for, upon power up of said glass forming shop, selectively loading said section computer means run tables with said stored job history indicia without communication from said central console.

Claim 8

6 .The system of any of claims 1 to 5 characterized by an auxiliary power source for selectively providing said power signal when said power source fails to provide said power signal; means, cooperating with said auxiliary power source, for sensing provision of said power signal by said auxiliary power source and generating a selected one of a programmed stop signal and an emergency stop signal, if said auxiliary power source provides said power signal for more than a predetermined time period.
