Abstract: Device for removing copies diverted from a conveyed stream thereof in a rotary cross cutter or delivery in a sheet-fed rotary printing press includes a device for decelerating the copies which are transported at an incoming conveying speed, the decelerating device being disposed so as to act upon both sides of the copies which are to be decelerated, a device for defining a copy-transport plane, a copy guide forming a diverter disposed down-line from the decelerating device and above the device for defining a copy-transport plane, and respective structures defining two conveying planes disposed down-line from the copy guide, at least one of the conveying plane-defining structures including a pneumatically acted-upon conveying device.

Abstract: Device for removing inspection or specimen copies at rotary cross cutters or deliveries in sheet-fed presses which, at a cutting station, cut a continuously supplied web of material into individual copies subsequently conveyable substantially free of contact and partly mutually overlapping in a given conveying direction in a copy-transport plane to a decelerating station disposed downline from the cutting station, includes at least one swivel cam assigned to the copy-transport plane, the swivel cam being activatable for penetrating the copy-transport plane so as to change the conveying direction of the copies.

Abstract: A production apparatus has several printing units with collecting tanks for receiving wash residue. A cleaning and waste disposal system within the production apparatus includes a collection feeding pipe connected to the collecting tanks of the printing units. A central collecting tank which is connected to the collection feeding pipe contains a pump module. A thermal dryer has a burner system. A burner feeding pipe is connected between the central collecting tank and the burner system for guiding fluid from the central collecting tank, through the burner feeding pipe, to the burner system during a production run.

Abstract: A folder delivery apparatus for single or multiple-stream production includes several delivery systems which are operable in parallel and can be driven independently of one another. During operation of the folder as well as during machine standstill, the delivery systems can be simultaneously shifted automatically or manually through adjustment units, in such a way that while adjustment takes place, the distance between the delivery systems can be set as desired within a minimal and a maximal setting position.

Abstract: A method of cleaning a mechanism having ink-conducting rollable cylindrical members in a printing unit of a rotary printing press includes spraying solvent into a nip between the ink-conducting rollable cylindrical members, rotating the ink-conducting rollable cylindrical members so as to squeeze the solvent through the nip between the rollable cylindrical members and thereby apply pressure in the nip to an ink/dampening solution mixture on the rollable cylindrical members for loosening the mixture, and removing loosened ink and impurities from the printing unit; and apparatus for performing the method.

Abstract: In a fan delivery unit of a folder having a plurality of fan discs arranged next to one another on a motor shaft, the fan discs being formed with a plurality of fan blades having fan pockets therebetween, there is provided a device for braking printed products. The braking device includes driven brake shaft disposed parallel to the motor shaft, a plurality of brake rollers corresponding in number to the number of fan discs being mounted on the brake shaft, and a device for driving the brake shaft via the motor shaft selectively in one of two rotational directions. The brake rollers and leading edges of the fan blades are cooperative for delaying travel of a printed product introduced into the respective fan pockets.

Abstract: A delivery device in a folding apparatus of a printing press includes a fan wheel or several fan wheels disposed next to one another. The fan wheels are formed of individual fan blades, between which fan wheel pockets are formed. Leading edges of the fan blades have a first profile and trailing edges of the fan blades have a second profile.

Abstract: The invention relates to a deceleration device for folded products, with which folded products following one behind the other are gripped by decelerable transport devices (6, 7) and conveyed. The oppositely arranged transport devices (6, 7) tracing a path of motion (15) are driven by a planetary gearing (16). While planetary gears (21, 22) rotate around a sun gear (23), an instantaneous centre P1 describe a cardioid which, via drive brackets (17, 18 and respectively 55) causes the transport devices (6, 7) to take different speeds during rotation of the planetary gears (21, 22).

Abstract: A folding apparatus for a rotary printing machine with two folding formers arranged one behind the other, nip rollers and cutting cylinders for two paper webs longitudinally folding by the folding formers, as well as deflectors, fans and deliveries for streams of folded products formed of the folded paper webs cut by the cutting cylinders, comprising a pair of first frame members carrying the nip rollers and the cutting cylinders therebetween, a second frame member at least partly disposed between the pair of first frames and intermediate the two product streams, idler means, diverter rollers and delivery devices for the folded products being mounted in cantilevered fashion on both sides of the second frame member.

Abstract: Radar target back scattering is controlled by an impedance loading technique. The target is loaded with a variable impedance that is adjusted in response to the frequency of any incident radar signal to achieve optimum reflectivity for that particular frequency. Either radar target cross section reduction or enhancement is achieved over a broad band of frequencies by appropriate control of a voltage variable capacitance diode.

Abstract: Interference from polarized signals is minimized by controlling the polarization of antennas having orthogonal dipole radiating elements. The antenna system utilizes microwave hybrids and phase shifters in a coaxial cable feed circuit that divides the power between horizontal and vertical dipole radiating elements. The circuit provides a variable antenna polarization that can be controlled to discriminate against interfering signals having any given polarization characteristics. Coaxial double folded baluns connect feed circuits to the dipole radiating elements and provide proper phasing and impedance transformation for efficient dipole operation.
