Title: Plate cylinder for offset rotary printing press - has optical or electrical image system for printing film and film replacement by take-up roll from roll of fresh film
Inventor: KUSCH HANS-JUERGEN
IPC: B41F13/08
Filed: 1992-07-23
Abstract: The plate cylinder of a rotary offset printing press has a clamped printing film (5) on the cylinder surface (4) to carry the printing material, applied at the machine by optical or electrical systems, and which can be exchanged. A supply roll (6) provides fresh film (5) and an empty roll (7) takes up the used film, which is moved by carrier rollers (10,11) with deflection rollers (8,9) at the cylinder mantle (4). The film rolls (6,7), and the film movement rollers (8-11), are contained in an insert (3) to be inserted and withdrawn on a channel (2) on the axial direction of the printing cylinder (1).$ A roller, powered by an intermediate wheel, is presented to the cylinder mantle (4) to take the leading end of the printing film round the plate cylinder (1), with guide tongues to insert the film between the second deflection (9) and carrier (11) rollers. A setting mechanism swings in the roller, and extends the tongues.$ USE/ADVANTAGE - The printing plate cylinder, for rotary offset printing, has a film as the printing plate which is prepd. within the machine optically or electrically, to give a change of printed images. The system allows a rapid change of printed images, with min. down-time, and accurate register for four-colour working.

Title: Operation of gas turbine plant burning solid fuel - involves waste heat from gas turbine to pre-dry fuel
Inventor: THELEN FRANZ DIPL ING
IPC: F02C6/00
Filed: 1992-08-28
Abstract: The water-containing solid fuel is pre-dried, by utilizing waste heat from the gas turbine (3). The fuel may be charged with the flue gases from the turbine, or with steam, which is generated by the waste heat of the turbine flue gases. Excess steam not used for fuel pre-drying is supplied into the combustion air of the fluid bed furnace. Before generating steam, the flue gases transmit part of their heat to the furnace combustion air. The steam for pre-drying is generated in a special low pressure stage of a waste heat boiler for a steam turbine (7), which is switched behind the gas turbine. USE/ADVANTAGE - Gas turbine plant, burning water-containing solid fuel, esp. lignite, operates with improved efficiency.

Patent DE-4314839-A1 (DE)
Title: Mine
Inventor: SCHOEFFL RAINER DIPL ING
IPC: F42B23/16
Filed: 1993-05-05
Abstract: A mine for a minefield which is divided into at least one mine group which consists of a plurality of mines has a base frame and a warhead to be fired for attacking a target object. Furthermore, the mine has a sound transducer 17 which receives the soundwaves radiated from the target object and converts them into target data, and a data interchange unit (data exchange unit) 35. The data interchange unit 35 consists of a transmitting unit 37 for transmitting the determined target data and the mine position data which indicate the position of the mine, and a receiving unit 39 for receiving the target data and the mine position data from the other mines in the mine group. The position of the target object is determined in a target location unit 25 from the target data and the position data of the mines which form the mine group. A detonating unit (fuze unit) 27 triggers the firing of the warhead when the target object is located in the area of effectiveness of the mine. Since the acoustic direction-finding basis of the mine according to the invention is formed by sound transducers which are arranged at a relatively large distance from one another, target location can be carried out with high accuracy. <IMAGE>
