Temperature control system for glass-shaping molds

Claim 2

A control system in accordance with claim 1 and in which said mold identification means employs a discrete binary code associated with each said mold.

Claim 3

A control system in accordance with claim 2 and in which said mold identification means employs a discrete binary code associated with each said mold.

Claim 4

In combination with a machine for forming articles from heated or molten material and which intermittently positions each of a plurality of article forming molds at a plurality of stations including material-charging, article-forming, article-takeout and mold temperature-sensing stations, a mold temperature control system comprising; A. individual adjustable means associated with each said mold for supplying cooling fluid to the respectively associated mold, B. means for sensing the temperature of each said mold positioned at said temperature-sensing station and producing signals representative of each respective mold temperature, C. means for producing identification signals for each respective mold arriving at said temperature-sensing station, D. means responsive to said identification signals for producing preset signals representative of a desired temperature for each respective mold, E. means receiving and responsive to the sensed and preset signals for each respective mold positioned at said temperature-sensing station to produce an adjustment signal representative of any adjustment required in said associated cooling fluid supply means for cooling the respective mold to its desired temperature prior to its next arrival at said sensing station, and F. means responsive to each said adjustment signal for adjusting the respectively associated cooling fluid supply means in accordance with the value of the respective adjustment signal.

Claim 5

A control system in accordance with claim 5 and in which said sensed and preset signals are electrical signals and said adjustment signal is a pneumatic signal.

Claim 6

A control system in accordance with claim 5 and in which said mold identification means employs a discrete binary code associated with each said mold.

Claim 7

A control system in accordance with claim 6 and in which said mold identification means employs a discrete binary code associated with each said mold.
