An opposed pair of inwardly facing radiant energy detecting sensors ( ) is positioned to sight on freshly formed glass containers (C) being conveyed on a side by side pair of conveyors ( ) to determine if any of the containers is misoriented from its desired orientation. Each sensor has a sharply focused fiber and lens assembly ( ) that is focused to sense radiant energy in a cone of view no greater than 1&deg;. A baffle ( ) is positioned between the conveyors and in alignment with the opposed sensors, to isolate the sensors from radiant energy emitted by containers on the away conveyor.

Method and apparatus for inspection of hot glass containers

A test apparatus for measuring operating characteristics of a position sensor coupled to a parison mold plunger for glass gob weight control in a press-and-blow individual section glassware manufacturing machine includes circuitry for connection to the sensor to provide a signal as a function of electrical characteristics thereof, a switch network for selecting among a plurality of differing electrical characteristics to be measured, and a display responsive to the sensor signal for displaying the selected and measured electrical characteristic of the sensor to an operator. The measurement circuitry includes a measurement bridge for measuring resistance characteristics of the sensor, and an amplifier circuit for measuring sensor output as a function of position of the plunger. The switch network selectively connects the sensor signal to the measurement bridge and amplifier circuit in differing modes of operation of the test apparatus.

Test apparatus and testing method for a position sensor in a glassware

Apparatus for sensing the passage of a gob of molten glass through a gob deflector or gob guide wherein a quick-disconnect nipple is fixed in a radial opening adjacent the lower end of the gob deflector. A hollow, quick-disconnect housing which is adapted to fit over the nipple is formed with a longitudinal passage therethrough, a washer-shaped holder lying in a plane, normal to the axis of said passage and intermediate the ends thereof serves to support a phototransistor with its leads extending into an end of the passage. A radial hole in the side of said housing has an elongated armored, stainless steel cable fixed thereto and an elongated high temperature insulating sleeve covering a pair of Teflong insulated wires extends within the cable with one of the wires connected to the emitter lead on said transistor and the other wire to the collector lead on the transistor. A high temperature epoxy fills the end of the housing about the wire connections with a plug closing the end of said housing containing said epoxy and a two pin connector plug connected to the other end of the wires.
