| Number | Title | Issue Date |
| 4899573 | Apparatus and an associated method for leak and volume inspection of containers The present invention provides apparatus and an associated method for testing containers for volume and leaks by employing a pump which provides rapid pressurized pulses simultaneously to a container being tested and a standard volume which may be a conta... | 02/13/1990 |
| 4832181 | Tracking system The cavity tracking system employs a tracking station adjacent a screw feed with closely spaced sensors which operate on a first-in first-out memory manner. When a container passes the first sensor the actual encoder "count" obtained at that time is compa... | 05/23/1989 |
| 4801319 | Apparatus and associated method for container sampling for inspection Apparatus for transporting and inspecting containers includes an annealing lehr disposed on one side of a primary conveyor and a stacker having a reciprocating pusher bar adapted to transport containers from the primary conveyor into the annealing lehr. I... | 01/31/1989 |
| 4791287 | Apparatus and an associated method for detecting haze or pearlescence in containers Apparatus and an associated method for inspecting translucent containers to determine whether haze or pearlescence exists include a light source and associated photodetectors which are in spaced relationship to permit passage of containers to be inspected... | 12/13/1988 |
| 4778999 | Method for detecting the presence of adhesive in a container and associated apparatus A method of inspecting a container for the presence of adhesive in desired locations includes providing an ultraviolet light source which impinges ultraviolet light on the locations where adhesive is desired and sensors which receive fluorescent light fro... | 10/18/1988 |
| 4757891 | Container handling device A rotating, vertically adjustable wheel is positioned above a linear conveyor chain in an operative position to move containers from a linear conveyor chain to an off-line station and then back to the linear conveyor chain downstream of the off-line stati... | 07/19/1988 |
| 4735645 | Method and apparatus for tempering glassware Ducts are provided to direct cooling gas onto the outer and interior surfaces of a rotating article of glassware that is heated to a uniform temperature above the strain point of the particular glass composition from which the glassware is formed in order... | 04/05/1988 |
| 4733973 | Method and apparatus for testing glassware 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 e... | 03/29/1988 |
| 4457957 | Method for applying an inorganic titanium coating to a glass surface An inorganic titanium coating, such as a hot end coating for glass containers, is applied to a glass surface by contacting the glass surface, which is at an elevated temperature, for example at least 371° C., with a solution of a tetraalkyl titanate such... | 07/03/1984 |
| 4261722 | Method for applying an inorganic coating to a glass surface Inorganic coatings for glass surfaces, especially hot end coatings for glassware, are produced by applying vapors of thermally decomposable metal compounds such as stannic chloride to the surface of glass at an elevated temperature and maintaining in a zo... | 04/14/1981 |
| 4248338 | Rotator for inspecting containers A device for interrupting the travel of an object, such as a container, on a conveyor belt during a manufacturing operation includes a driven wheel and at least one idler resiliently urged towards the drive wheel. Both wheels are spaced apart a distance l... | 02/03/1981 |
