Patent number: 4600879Abstract: Shown is an apparatus and method of use where microwaves transmitted through volatiles include water vapor driven from an adequate polymer sample by heating in a closed test cell. A pump moves a predried gas and those volatiles at pressure and flow rate to a microwave transducer including a pair of antennae horns aimed at one another, one with a microwave transmitter oscillator and the other with a receiver detector. The volatiles are brought transversely across the open end of the oscillator antenna horn by a conduit. The particular orientation of the conduit is important to the accuracy of the measurement. A moisture absorbent material inserted axially into the conduit restrains the flow of volatiles changing same to liquid form. Loss of microwave energy due to the water vapors in the volatiles is measured at the output of the detector. Microwave energy absorbent material surrounds the transducer.Type: GrantFiled: June 15, 1984Date of Patent: July 15, 1986Inventors: John P. Scully, Richard Ward

Patent number: 4485663Abstract: This disclosure relates to a product, the process for making same from precoated metal and the tool used for making the product. The product is a concurrently drawn and ironed sanitary food can wherein the side wall thickness of the container is relatively uniform and approximately 0.001" thinner than the thickness of the starting material. The process is a concurrent multiple drawing and ironing operation wherein the diameter and the wall thickness are reduced in each of a plurality of operations. Finally, the tools used for each drawing and ironing operation have particular configurations designed to permit this concurrent forming of both the diameter and the side wall thickness.Type: GrantFiled: December 13, 1983Date of Patent: December 4, 1984Assignee: American Can CompanyInventors: Vance B.

Patent number: 4471687Abstract: The disclosure describes a new type of pressure cylinder to provide clamping force while fabricating deep drawn metal parts. The piston is a hollow cylinder connected to the clamping pad. The drawing tools are connected to the draw ram by a rod passing through the hollow piston. This arrangement provides a smaller overall press height and an axisymmetric clamping force. In addition, the symmetry of the parts described means that the wear parts can be reversed to double their useful lives.Type: GrantFiled: November 17, 1981Date of Patent: September 18, 1984Assignee: American Can CompanyInventors: Richard P.

Patent number: 4467933Abstract: A closure for sanitary or food cans made from high temper plate to withstand the high pressure developed during processing without permanent distortion or buckling. An upwardly directed reinforcing annular bead is introduced concentric with a countersink groove which is disposed between the end flange and said annular bead. The ends are further contoured with a series of transitional steps or panels inward of said annular bead. These features enhance the strength of the closure without inducing substantial warpage.Type: GrantFiled: October 16, 1981Date of Patent: August 28, 1984Assignee: American Can CompanyInventors: Harlen E.

Patent number: 4447699Abstract: A signal emitted from a transducer responsive to the relative power applied during a welding process is enhanced electronically and mathematically to be of use in controlling welder operating parameters and/or in rejecting defective welds. Electronically the signal refined to minimize unnecessary noise in the signal and mathematically the signal is modified and analyzed against a standard. In a high speed welding operation automatic means are necessary to assure weld quality and control welder operation since the rapidity with which the welding takes place is too fast for manual readjustment.Type: GrantFiled: November 5, 1982Date of Patent: May 8, 1984Assignee: American Can CompanyInventors: Vance B. Gold, Edward F. Kubacki, Thomas Krewenka

Patent number: 4416389Abstract: Shown is an easy open closure for a container wherein there is a ring-pull tab held by an integral rivet to the central circular recessed panel of the closure. The tab however, rests on a raised portion of that panel which portion includes various areas of weakening and strengthening and a displaceable panel therein defined by a score line. The raised portion positions the tab to protect it against abuse loadings due to handling and shipping full containers having the closure. About the periphery of the central circular panel is a stepped wall portion except near the area of the score line for the displaceable panel where the wall is unstepped.Type: GrantFiled: October 26, 1982Date of Patent: November 22, 1983Assignee: American Can CompanyInventors: Harlen E.

Patent number: 4395864Abstract: An automatic system for accumulating, counting, stacking and bagging can ends. The system is designed to protect the end against damage by minimizing the handling of the end. An automatic dispenser counts and dispenses can ends to one of a pair of end stacks which are mounted for rotation about a vertical axis. The end stacks are indexed from a loading position to an unloading position where the filled stack is pivoted from a normally vertical attitude to a horizontal discharging attitude. Ends are discharged to an automatic bagging system for packaging and storage.Type: GrantFiled: January 28, 1981Date of Patent: August 2, 1983Assignee: American Can CompanyInventors: Gerald R.

Patent number: 4386708Abstract: A system for the reject of a single container from a row of multiple closely spaced containers on a moving conveyor. A circuit supplies a signal to a reject mechanism which is a solenoid actuated air blast to remove the container accurately. The circuit combines a shift register output with blanking signals in a first gate and a container position control sensing signal with the output of the first gate in a second gate to produce the appropriate reject signal. Mechanical fine tuning is provided to enable positioning the container signal within the appropriate time window.Type: GrantFiled: February 12, 1981Date of Patent: June 7, 1983Assignee: American Can CompanyInventor: Walter J.

Patent number: 4376883Abstract: To measure the relative power during a welding process, a position sensitive transducer is attached to a welding electrode to submit a signal in response to electrode motion. An accelerometer, carried on an axle of an electrode roll for a Soudronics pulse type resistance welder, will emit a signal indicative of the quality of the weld. The accelerometer measures the forging taking place during welding by means of its position sensitivity and the amount of forging has been found to be a function of the characteristics of the weld.Type: GrantFiled: July 30, 1980Date of Patent: March 15, 1983Assignee: American Can CompanyInventors: Tan K.

Patent number: 4372720Abstract: A method and apparatus are disclosed and can be used to fabricate a complete container end closure including an inwardly tipped cover hook located along the peripheral extremity. The apparatus and its use in performing the method are unique in that one tool does all the forming to produce the complete end closure. More particularly, the cover hook is preformed by a first tool operation and then finally formed by a subsequent step wherein the preformed end is reformed to a final configuration in a step which is completely independent of the first tool.Type: GrantFiled: September 4, 1980Date of Patent: February 8, 1983Assignee: American Can CompanyInventors: Frank J.

Patent number: 4372462Abstract: A retained ring type lever tab for easy open containers. The tab is provided with two dog leg levers which join at the forward end to form a triangular nose. These levers which in cross section are made up of a pair of parallel flanges 0.050" in width connected by an outer curl of radius 0.030" are particularly effective in transferring the opening force to the displaceable panel in the end. The tab is characterized by a low weight and a high mechanical advantage.Type: GrantFiled: May 12, 1981Date of Patent: February 8, 1983Assignee: American Can CompanyInventors: Karl O. Dassler, Neal E. Langseder
