Abstract: An apparatus for imprinting a code or other marking on articles, such as capped jars, which comprises a printing or coding wheel having a series of circumferentially spaced printing die elements and rotatably mounted at a printing station above a straight line conveyor on which capped jars or other articles, are advanced, the wheel being disposed at an elevation to bring the die elements into engagement with the tops of jars advanced to the station and a drive for the wheel which includes a differential gear system for accelerating or decelerating the printing wheel and a stepping motor which is responsive to sensors spaced along the path of advance of the jars as they approach the printing station and operating to sense the location of the jar tops relative to the printing station. The sensors are connected through electric circuitry with a control device including a timer whereby the rotation of the printing wheel is adjusted so that the die elements match the spacing of the advancing jar tops and a die element is engaged with each successive jar top to print a code thereon.

Abstract: Particles of plastic material are attracted to a mold surface by impressing an electrostatic charge on the particles subsequent to their deposit, minimizing disturbance of the deposition stream and sticking of powder in the deposition apparatus. A roll deposition unit and corona bar are employed in association with a rotating mold to form a cylindrical member from powdered plastic material. The unit deposits powder in a strip zone lengthwise of the mold. The corona bar is positioned externally of the roll case, parallel to and coextensive with the roll and closest to the cylindrical mold wall in a plane outside the stream of powder flowing from the roll to the mold wall. When the bar is charged and the mold is grounded, the resultant discharge is largely concentrated outside the stream, minimizing electrostatic effect on particles in the stream.

Abstract translation: 塑料材料的颗粒通过在其沉积后在颗粒上施加静电电荷而被吸引到模具表面，最小化沉积流的干扰和粉末沉积在沉积设备中。 与旋转模具相关联地使用辊沉积单元和电晕棒，以从粉末塑料材料形成圆柱形构件。 该单元将粉末沿着模具纵向的条带区域沉积。 电晕棒位于辊壳外部，平行于辊并与辊共同延伸并且在从辊流到模具壁的粉末流的外侧的平面中最接近圆柱形模具壁。 当条被充电并且模具接地时，所得的排出物大部分集中在流体外部，从而最小化对流中颗粒的静电效应。

Abstract: This disclosure relates to a dampener for suppressing the normal electrode bounce which occurs when lapped portions to be welded move in between a pair of roller electrodes and force the electrodes apart. The dampener is particularly constructed to be operable primarily at the time the lapped portions move in between the electrodes.
