Abstract: A dwell time control system and method for automatically adjusting the selection and timing of a sequence of pressures used to drive the plunger in a parison mold during the parison forming process. The timing of characteristics of the observed press curve from one or more previous parison forming cycles are ascertained and used to control the timing of the changes in pressure during a subsequent parison forming cycle. The timings of these changes of pressure are determined as predetermined percentages of the timings of the characteristics in order to prevent the blow mold from being forced open and in order to prevent the occurrence of an overpressed finish.

Abstract: A method and apparatus for monitoring glass articles produced in a glass molding machine having a plurality of production units. The glass articles are always conveyed in the same sequence, relative to the production units, through a conveying stretch. Each glass article, as it passes through the conveying stretch, is provided with a marking having an individual serial number, wherein assigned to the marking is data related to the production process of each such glass article. The glass articles are supplied via the conveying stretch, and in the same sequence, to a continuous annealing oven. The glass articles are subsequently subjected to a defect checking process.

Abstract: A sensor structured as a two-part oscillator is employed in a device for measuring the position of a movable operating member of a machine, such as a plunger in a glassware forming machine. The plunger is attached on a piston rod of a piston/cylinder unit cooperating with the measuring device for the continuous measurement of the position of the plunger during its stroke. The first part of the sensor is a resonance circuitry formed of a coil and a capacitor. The capacitor has first and second capacitor elements stationary relative to one another and a third capacitor element movable with the piston rod relative to the first and second elements. The resonance circuitry is disposed in the cylinder of the unit such that the resonance frequency of the resonance circuitry is variable in proportion to the change of capacitance of the capacitor in response to the change of the position of the piston rod relative to the cylinder.

Abstract: A process for determining a weight of free-falling molten glass gobs has the steps of providing an electromagnetic alternating field, passing a glass gob through the electromagnetic alternating field in a free fall, measuring resultant eddy current losses of the electromagnetic alternating field caused by the glass gob during passage through the electromagnetic alternating field, and determining a weight of the glass gob via the detected resultant eddy current losses.
