Title: Offset perfecting printing
Inventor: FISCHER HERMANN
IPC: B41F7/02
Filed: 1983-07-07
Abstract: Several printing units (1 to 4) each having two blanket cylinders (5, 6; 10, 11) between which the web is conveyed for first and second printing, are arranged one behind the other in the running direction of the web (7). In order to avoid doubling of the printed image caused by web oscillation, the web is guided in such a way that it runs into a printing unit with partial wrapping around one of the blanket cylinders and runs out of this printing unit at approximately right angles to a plane containing the axes of the blanket cylinders. To achieve this the planes (A and B) containing the axes of the respective blanket cylinders (5, 6, 10, 11) are inclined to each other at an included angle (???) and the cylinders of the adjacent units are staggered relative to each other in the vertical direction.   In other embodiments the partial wrap around on the entry side of a printing unit and the exiting perpendicular to the plane containing the axes of the blanket cylinders is achieved by means of a web deflecting element, which may be adjustable, between the printing units. <IMAGE>

Title: System for determining position on airport taxiways
Inventor: MARTINEZ ARANZANA VICTOR
IPC: G08G5/06
Filed: 1985-03-01
Abstract: Photoelectric barriers 1 are provided along taxiways, runways, etc. at an airport so as to detect when an aircraft interrupts an infrared beam. Coded information is transmitted to receivers 5 and decoders 6 in the aircraft and to similar equipment in the control tower. A display 7 in each aircraft and a display Sin the control tower give information on the position of each aircraft on the taxiways, runways, etc and a warning signal when the aircraft is at the entrance or exit of intersections. Each pilot and traffic controller is thus aware of the position of each aircraft in the airport and with respect to adjacent aircraft, and is made aware of hazardous positions at intersections. Airport safety is therefore greatly improved and the danger of collisions is substantially reduced. <IMAGE>
