Abstract: A high-power resistor comprises a plurality of resistor elements (1), made of sheets of an electrically conductive resistance material, with a first (13) and a second (14) terminal. The resistor elements are mutually separated by disc-shaped insulating first shims (2). Said first and second terminals are connected to adjacently located resistor elements so that the respective first terminals are connected to a first terminal and that the respective second terminals are connected to a second terminal. Two adjacent resistor elements form a current path, whereby, viewed in a direction perpendicular to the plane of the sheets, said first and second terminals, respectively, are so mutually positioned that, for a current supplied thereto, the current path in one resistor element substantially overlaps the current path in an adjacent resistor element and hence carries current in mutually opposite directions in the two adjacent resistor elements.

Abstract: A sheet-fed press includes a first press cylinder and a second press cylinder. A first air supply chamber and a first air vent is located in the upstream segment of the flow of a sheet. A second air supply chamber and second air vent is located in the downstream segment of the flow of the sheet. Air from the second air supply chamber is blown through the second air vent in the direction that the second cylinder is rotating.

Abstract: The objective of this invention is to provide a sheet-fed press which will prevent sheets of paper from moving around or flapping, and allow the sheets of paper to be conveyed in a stable fashion even when a skeleton cylinder is used as the intermediate cylinder.

Abstract: An article feeding apparatus comprising a driven roller and a pressure roller resiliently urged toward the driven roller. Movement of the pressure roller toward the driven roller is controlled by means of a damper containing material having electro-rheological properties. An electric potential of controlled magnitude is applied selectively to the material to control movement of the pressure roller. The apparatus is described in relation to a print drum and impression roller of a franking machine.

Abstract: A label issuing apparatus which feeds labels adhered in a line on a base carrier paper, is arranged to stop the feed of the labels at a first printing position and to print thereat on each label, and then to feed the labels so that printed labels issue from a label issuing outlet. The label issuing apparatus is comprised of a keyboard including a RAM having first and second memory areas, a set key, an execution key and ten numerical entry keys. The keyboard stores first and second feed distance data into the first and second memory areas when the keys are operated, and a feed control unit feeds the label carrier paper through a distance corresponding to the first feed distance data when a leading edge of a printed label is detected. The feed control unit sets and prints the label at the first printing position, and then feeds the carrier paper through a distance corresponding to the second distance data to define a second printing position.

Abstract: A card selecting and address printing apparatus to select a card having specified information from among a group of cards bearing thereon coded information and a master printing address and to transfer-print the specified information from the card onto another sheet, having a card hopper for the group of cards including the card to be selected, a card feeder to feed the cards therefrom one at a time, an optical card reading and signal generating means for comparing the coded information on the card being fed with stored information and generating a signal, a card pass selecting mechanism for selecting one of two card paths according to the signal generated, a workpiece hopper and feeder for feeding paper one at a time from the workpiece hopper to a waiting station, holding it there and feeding it to a printing station in response to the signal generated, a printing means for transfering the master printing address on the selected card fed through the card pass selecting mechanism onto the paper fed from the w

Abstract: A transfer-printing process and apparatus for transfer-printing from a master card onto a work piece. The process starts by manual insertion of the master card into a gap provided between press rollers. By the insertion of the master card, the work piece is fed into a work piece path and the surface thereof is wetted during its movement along the path. The work piece thus fed and the master card sustained between the gap are registered with each other as desired and pressed for transfer-printing by the rotation of the press rollers. The work piece and the master card are then delivered to the insertion inlet of the master card.

Abstract: A small desk-type addressing machine with automatic card feeding and manual control for registration adjustment. The printing station uses a narrow large diameter segmented printing roll made of relatively soft rubber on an auxiliary shaft. A single clutch controls the card feeding and the moistening operations and serves to drive the printing roll. The frame housing is made of three interconnected sheet metal boxes with a prestressing element that maintains the cantilevered upper component a fixed distance above the table component. The upper component has a pivotable portion for giving access to the moistening station.

Abstract: A duplicating machine for duplicating printed material from selected master cards onto a workpiece comprises a master card feed station including a feed device for feeding cards to a print station and a workpiece feed station including a device for feeding workpieces to a moistening apparatus and to the print station. Also provided is a card reading device for detecting predetermined information characteristics stored on an adjacent master card in a stack and for determining whether the printed material on that card is to be duplicated. If the material is to be duplicated the reading device provides a signal to a control system that actuates the workpiece feed device for feeding the workpiece to the print station.

Abstract: A novel printing press for printing a large number of different messages on sequentially fed stock, without requiring the use of a large printing drum, which also eliminates the requirement for collating. A multiplicity of drum segments are provided each having similar radii of curvature, for carrying printing type on their convex surfaces. A pressure wheel is located adjacent a pressure plate, the pressure wheel having a similar radius of curvature as each of the drum segments. The drum segments are carried each in turn around at least part of the pressure wheel between the pressure wheel and pressure plate, whereupon stock fed therebetween can be imprinted.

Abstract: An improved printing apparatus control system regulates the operation of a sheet feed assembly which sequentially moves sheets of material to and from a printing station and a plate feed assembly which sequentially moves printing plates to and from the printing station. A photocell detects initial movement of a leading end portion of the printed sheet of material away from the printing station under the influence of the sheet feed assembly. This photocell is also utilized to detect when the printed sheet of material has completely exited from the printing station. A second photocell detects the presence of the succeeding sheet of material at the printing station. The control system also includes a sensor which detects the removal of one printing plate from the printing station, the absence of a printing plate at the printing station, and the subsequent arrival of the next succeeding printing plate at the printing station.

Abstract: Duplicating apparatus for reproducing printed matter from a master card onto labels. The appartus is of very simple construction and enables adjustment of the position of the printed area on the labels.
