Abstract: The present invention relates to non-pigmented jet ink compositions and to a method of producing opaque coded messages therewith. The compositions comprise, on a weight basis, between 2 and 15% of a gellable cellulose ester having a hydroxyl content of from 2 to 8%, from 1.5 to 15% of a binding agent selected from the group consisting of alkali soluble rosin type and maleic type resins, polyvinyl acetate resins, and acrylic resins, and a solvent blend, the blend consisting essentially of an organic solvent system and a non-solvent, said non-solvent comprising from 2 to 10% by weight of the ink compositions. Preferred solvents are methanol, acetone, methyl ethyl ketone and ethyl acetate, while the preferred non-solvent is water. Upon evaporation of the solvent blend, the resultant dry films scatter light incident thereto whereby the opaque images are produced. In a particularly preferred embodiment, a hygroscopic salt is included in the composition as an opacity enhancement agent.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A material for protecting the inside surface of a side seamed cylindrical container is disclosed. The material is of a thixotropic nature whereby edge protection is assured for a lap seam, a can seam or a welded seam, the latter being either a lap or butt-type joint. All of the foregoing constructions exhibit certain internal surface irregularities exposing raw metal to the interior of the container which must be appropriately covered in order to maintain sanitary protection of the contents ultimately packed within the container. Thixotropic materials have been found to provide the requisite surface adherence after application and until curing; thus, affording improved coverage of the various raw surfaces.
