Patent number: 7378047Abstract: A method of inspecting wall thickness of blow-molded plastic containers includes providing a blow-molder having a plurality of molds and a plurality of associated spindles. The containers are inspected by impinging infrared light thereon and detecting the portion of the infrared light that passes through the container and converting the same into corresponding electrical signals which are delivered to a microprocessor. The microprocessor compares the electrical signals with stored information regarding desired wall thickness of the container and emits output thickness information. The microprocessor receives signals from sensors associated with the blow-molder relating to the position of the molds, the identity of the molds and the identity of the spindles in order that the wall thickness information that is determined by inspection can be associated with specific molds and spindles. The wall thickness information may be averaged over a period of time or a number of containers.Type: GrantFiled: January 24, 2005Date of Patent: May 27, 2008Assignee: AGR International, Inc.Inventors: Craig Alan Birckbichler, Sudha Christy Jebadurai, Georg V.

Patent number: 7374713Abstract: A method of manufacturing plastic containers. The method may comprise the steps of (1) forming a plastic container from a preform in a blow-molder, where the blow-molder comprises a plurality of molds and spindles; and (2) inspecting the plastic container after formation in the blow-molder. The containers are inspected by impinging infrared light thereon and detecting the portion of the infrared light that passes through the container and converting the same into corresponding electrical signals which are delivered to a microprocessor. The microprocessor receives signals from sensors associated with the blow-molder relating to the position of the molds, the identity of the molds and the identity of the spindles in order that the information that is determined by inspection can be associated with specific molds and spindles. The information may be visually displayed so as to provide feedback regarding the inspection process.Type: GrantFiled: October 5, 2006Date of Patent: May 20, 2008Assignee: AGR International, Inc.Inventors: Craig Alan Birckbichler, Sudha Christy Jebadurai, Georg V. Wolfe, Ronald A. Puvak, William E. Schmidt

Patent number: 7354538Abstract: A system and a method for controlling a container manufacturing machine include a thickness monitor (10) for determining an average wall thickness of containers produced by the machine. The system uses the average wall thickness to adjust machine control to change operation of the machine and adjust the quality of the containers being produced. The system also responds to feedback from pneumatic devices (104), heaters (103), mechanical devices and temperature sensors (108, 109) to determine corrections to be made to the machine operation.Type: GrantFiled: June 10, 2004Date of Patent: April 8, 2008Assignee: Petwall, LLCInventors: Frank E. Semersky, Ronald A. Puvak, Scott W. Steele, Donald Wayne Miller, William E. Schmidt

Patent number: 4733973Abstract: A glass container to be tested for resistance to thermal schock and impact simulation is first filled with hot water to a point of overflowing. The hot water fill is terminated and the excess permitted to run off. Thereafter the bottle is closed and the external surface is sprayed with cold water to induce a thermal stress upon the container. After the cold water spray a low level internal pressure load is applied to the container following the thermal shock load. The application of the internal pressure extends partial fractures resulting in complete breakage of the container or a break resulting in a decrease of pressure in the container, indicating a failure.Type: GrantFiled: May 12, 1986Date of Patent: March 29, 1988Assignee: American Glass Research, Inc.Inventors: David R. Machak, Ronald A. Puvak, Russell D. Southwick
