    摘要: In an offset duplicating machine, an implement for marking, such as perforating, slitting, scoring or the like, each printed sheet conveyed through the machine; for transverse marking, a first marking strip is affixed lengthwise on an impression cylinder and a rotatable counter-roller is mounted adjacent and at a skew inclination to the impression cylinder; the counter-roller has an outer surface of hyperboloidal shape which allows the strip to progressively mark the passing sheet. By grooving the counter-roller or by varying the distance separating it from the impression cylinder, additional marking strips may be affixed to the impression cylinder to provide various marking configurations on the printed sheet.

    摘要: Disclosed is a reactor or sparging vessel suitable for use for reaction mixtures containing vapor and/or gas bubbles. It comprises a mechanical agitation means suitable to redistribute flow radially and at least one perforated plate suitable to provide resistance to axial flow. In desirable embodiments it may include at least one electrically or hydraulically-stimulated rotatable shaft upon which at least one blade impeller is mounted, and at least one perforated plate oriented such that it provides resistance to axial flow. The perforated plate may have channels therethrough whose cross-sectional dimension is smaller than the projected average diameter of the vapor and/or gas bubbles. The reactor or sparging vessel offers improved flow dynamics, including reduced back mixing and narrowed residence time distribution. A method of employing the reactor for a reaction mixture containing vapor and/or gas bubbles is also disclosed. An impeller blade having two curvatures is also disclosed.

    摘要: The attachment device is adapted to be mounted to the delivery end of an offset duplicating machine and includes: a frame; an impression cylinder rotatably mounted to the sidewalls of the frame; a gripper bar device which is also rotatably mounted to the sidewalls of the frame and which is disposed between the duplicating machine and the impression cylinder, the gripper bar device including a gear wheel in meshing engagement with a gear wheel of the duplicating machine and with a gear wheel on the impression cylinder, the gripper bar device further including a series of members for gripping a sheet received from the duplicating machine and for conveying it to gripping elements on the impression cylinder; and character printing means mounted to the frame, including a gear wheel in meshing engagement with the gear wheel of the impression cylinder and a character numbering device rotatably mounted to contact successive sheets conveyed on the impression cylinder so as to print consecutive characters thereon. Means are also provided to avoid the printing of a character and the changing of a character should there be a void in the successive feeding of sheets in the attachment.
