Abstract: An improved row crop header for harvesting crops planted in rows.  The improved row crop header has a plurality of row units mounted on a frame such that each row unit has at least one gatherer operating in a gatherer plane that is oblique to a row unit plane that passes through the structure of the row unit.   The reduced projected width of the gatherer along the row unit plane reduces the width of a row unit. The adjacent gatherers of two adjacent row units overlap as they operate in offset planes.  The overlap permits the row units to be arranged closer together on the frame.  The closer arrangement together with the reduced width of the row units allows the row crop header to harvest narrower crop rows than the existing corn heads.  A method is also provided that uses the improved row crop header to harvest narrower crop rows than in the past.

Patent CA-2234506-A1 (CA)
Title: Magnetic trip assembly and circuit breaker incorporating same
Inventor: JUDS MARK A
IPC: H01H71/74
Filed: 1998-04-09
Abstract: A solenoid type magnetic trip assembly for a molded case circuit breaker includes an armature biased against an adjustable stop by a tension spring to set the initial gap for the magnetic trip, so that the spring bias remains constant for the full range of the initial gap. The armature includes an elongated magnetically permeable member mounted by a frame to slide longitudinally along a pair of guide rails. The frame defines a trip surface axially aligned with the elongated magnetically permeable member which engages a trip arm on a trip bar to trip the circuit breaker in response to a predetermined level of overcurrent. A bimetal providing a thermal trip function is cantilevered from a support spaced from the trip bar by the armature, but has a terminal portion at the free end projecting toward the trip bar and through which the elongated magnetically permeable member of the armature extends. A radially enlarged slug on the free end of the elongated magnetically permeable member of the armature is subjected to a magnetic force opposite to the force generated by load current tending to pull the armature into the solenoid coil. This opposing force increases as the initial gap increases, placing the slug closer to the magnetic frame, so that a greater range of trip currents can be selected despite limited room for armature travel,. A gap in the magnetic frame prevents short circuiting the magnetic field where the few turns of a large gauge coil wire produce an unsymmetrical winding. A magnetic shield protects the bimetal from deformation during high current short circuits.

Filed: 1996-12-02
Abstract: A method is described for labeling containers (22, 30 and 44) with a label (12, 32 and 40) that facilitates a de-labeling process.      During the labeling process, a frangible region (34 and 42) is formed on the label (12, 32 and 40) which is then applied to containers (22, 30 and 44). After consumer use, the labeled containers (22, 30 and 44) are collected for de-labeling. In the de-labeling process, a mechanical force is applied to the frangible region (34 and 42) which causes the label (12, 32 and 40) to flag outwardly from the container (22, 30 and 44). A separating device then removes the label (12, 32 and 40) from the container (22, 30 and 44). The de-labeled container (22, 30 and 44) may then be cleaned for reuse and provided with a fresh label.
