Abstract: A mold is disclosed which has a vertical front face having a glass object surface defined therein and a stepped vertical rear surface. The upper portion of the rear surface projects outwardly from the lower portion of the rear surface. The lower rear surface includes the top surface of two vertically spaced pairs of “T”s.
Abstract: A machine for operating on a glass bottle. A carriage is displaceable by a servo motor having three lead lines. The rotation of the servo motor is stopped when power has been removed by shorting regenerative resistors to the three motor leads. The stopped servo motor is held at its stopped position by connecting a direct current power supply to two of the three servo motors.
Abstract: A pushout mechanism includes a pusher finger assembly which utilizes air jets to facilitate the location of bottles with the pockets defined by the fingers. The air jets are defined by in a projecting post in an orifice member which can be quickly released from the arm of the finger. The location of the air jet can, accordingly, be quickly adjusted by substituting an orifice member having a shorter or longer post.
Abstract: A glass container inspection machine is disclosed for inspecting glass stippled bottles for defects. Stippled bottles are supported at an inspection station and are illuminated with a light source. The stippled bottle is imaged a pixel matrix with the pixels of the image varying in intensity from bright to gray at the points of stippling. A computer evaluates the pixels of the image including a look up table for values to be assigned to specific light intensities from light to black, the plot of the look up table having a high gain portion from black to gray and a continuous low gain portion from gray to white.

Abstract: An I.S. Machine is disclosed which includes a structure displaceable from a start location to an end location and a motor for displacing that structure. A control controls the operation of the motor to displace the structure and the speed of displacement can be varied by changing inputs to the control. A fixed period of time from a datum to the ideal time when the structure will be displaced to its end location is set and compared with an actual period and a selected input to the control is provided for changing the speed of the structure to reduce the difference.
Abstract: A camera based inspection system for inspecting glass bottles made in a glass-forming machine. A single picture shows the heat distribution of an inspected portion of the bottle over a period of time whereby the operator will see a loss of stability in the glass process.
Abstract: A machine for inspecting bottles which has a conveyor for conveying bottles at a first velocity. A bottle spacing mechanism receives bottles conveyed by the conveyor at a first location and releases bottles on the conveyor at a second downstream location.
Abstract: The invention generally relates to a method for muting an alerting portable device such as a ringing cell phone or alarming PDA. Specifically where muting is activated in a means not requiring direct contact with the keys of the device. The indirect contact such as a hand pat or smack is detected within the device by a sensor such as a microphone or accelerometer. Control circuitry detects active indirect contact and then mutes the alert, and or does some other programmable operation.
Abstract: A mold cooling system is disclosed for the blank mold halves of an I.S. machine. The mold halves are supported at their bottom by a lower hanger assembly which includes a discrete plenum for each of the mold halves. Each plenum is isolated and has its own air supply which includes an adjustable flow control. This provides complete control of the mold cooling process.
Abstract: An L.E.D. matrix light source illuminates a bottle at an inspection machine. A vertically periodic intensity pattern is defined to facilitate the identification of defects. The L.E.D. that locates the top of the bottle is identified and a peak of the pattern is located at that L.E.D.
Abstract: A machine for inspecting a container which is being conveyed along a linear path. The machine has cabinets situated in front of the conveyor path at either side of a central open area in front of the conveyor path which is to be used by an operator for servicing the conveyor. The interior sides of these cabinets are open for access to electronics and the central opening is closed by a pair of doors which are releasably attached to the sides of the cabinets and can be push in to provide access to the central area and can be pulled from the cabinets to provide access to electronics through the open sides of the cabinets.
Abstract: An inspection system completes two inspections with a single camera. In one inspection polarized light illuminates the side wall of a bottle, passes through a pair of electrode surfaces on either side of a ferroelectric crystal which do not change the polarity and passes through a polarizer to image on the camera. In a second inspection the polarized light is rotated 90° by the same structure so that only light rotated as a result of stress in the bottle passes through the polarizer and images on the camera as a defect.
Abstract: The man-machine screen interface can be switched to one of a plurality of back lights so that an operator can define any one of these back lights on the man-machine screen interface as a desired back light for inspecting a transparent container.
Abstract: A machine for inspecting a container which is being conveyed along a linear path. The machine has spaced left hand and right hand cabinets in front of the linear path with the space therebetween being space in which an operator can stand to be proximate to the linear path. The machine has left hand and right hand inspection stations which include a left-hand assembly located in front of the linear path and a right hand assembly located in front of the linear path. These assemblies are pivotally mounted about vertical axes so that they can be pivoted from a closed position proximate the liner path to a retracted position away from the linear path. At the retracted position an operator can enter the machine and service the inspection stations.
Abstract: A motor controller system for operating a plurality of step motors. The step motors are arranged in a number of motor groups each having no more than “N” step motors. A group multiplexer will deliver feed signals to the correct numbered motor of a motor group. There is a single 1 axis motor control and an output drive for each motor number of a group. The 1 axis motor control supplies the group multiplexer with motor group data so that the group multiplexer will supply the correct motor group and the 1 axis motor control also individually enables the motors of that group which are to be operated and conjointly supplies all the output drives with a desired feed signal.
Abstract: A machine for inspecting bottles. The machine has a belt conveyor with upper and lower opposed pairs of belt drives. Each belt drive includes a casing which supports opposed drive and idler pulleys which support a belt for displacement. A motor drive, mounted on the casing, drives the drive pulley.
Abstract: A takeout grips a formed bottle at a blow station of an I.S. machine and releases the bottle onto a conveyor and returns to grip the second bottle formed in the blow station following the bottle removed by the takeout.
Abstract: A blow mold assembly for an I.S. machine for blowing a parison of glass and cooling the blown parison into a formed bottle which can be removed from the blow mold. A blow head is lowered onto a blow mold and final air is applied. A predetermined time after the blow head engages the top surface of the blow mold the blow head is lifted a selected vertical distance above the top surface of the blow mold to an exhaust position allowing cooling air to escape from the blow mold. The selected vertical distance is selected so that at least a minimum pressure will continue within the formed bottle. The blow head is maintain at the exhaust position for a predetermined time and then retracted. The selected vertical distance and the predetermined time can be set as desired.

Abstract: A takeout mechanism for an I.S. machine grips a formed bottle at the blow station and carries the bottle to a first position spaced above a deadplate. The bottle is held at this position for a period of time and then is lowered to a position proximate the deadplate whereupon it is released.
