摘要： The longitudinally transported strip passes and is pressed between two cooperating transport rollers. The rotation axes of the two rollers are normally parallel to each other. One roller is swingably mounted about a swing axis which intersects and is perpendicular to the rotation axis of the other, non-swingable roller. Edge sensors are displaced by the lateral edges of the transported strip, when the strip improperly shifts transversely. The force thusly exerted upon an edge sensor is transmitted, via a force-multiplying lever system, to the swingable transport roller, swinging the latter to a position such that the swung transport roller exerts upon a major surface of the transported strip a force whose transverse component is directed opposite to the direction of the improper transverse shift, resulting in automatic recentering.

摘要： A rotary format-mask carrier plate carries a plurality of removably supported format masks for originals to be copied and carries them back and forth between the copying station and a change station, where the masks can be exchanged for others and/or copied originals replaced by not yet copied originals. Downwardly extending projections on the format masks extend through and beyond corresponding openings in the rotary carrier plate. While a format mask is transported from the change station to the copying station, it rests on the carrier plate. When it reaches the copying station, the carrier plate descends an amount such that the projections on the format mask come to rest on correspondingly arranged stationary electromagnets, thereby transferring the weight of the format mask to the stationary electromagnets. The carrier plate drops a further amount, losing physical contact with the format mask at the copying station. In this way, shaking or vibration of the format-mask carrier plate, resulting from laying on and removal of originals and format masks at the change station, cannot be transmitted to the format mask and original presently located at the copying station.

摘要： Apparatus for removing dust from the flat surfaces of stationary or moving sheets, webs, plates or similar objects has a unit which converts a low-pressure laminar air stream into a pulsating air stream. The pulsating stream contacts the surface of an object simultaneously with ultrasonic radiation. The direction of flow of the pulsating air stream, which can be ionized, may be parallel with or at right angles to the direction of propagation of ultrasonic radiation.

摘要： Apparatus for transferring photosensitive sheets from the transporting plane into the copying plane of a photographic copying machine has a suction chamber with a perforated cover having a flat upper side which defines the copying plane. The interior of the suction chamber is subdivided into one or more centrally located primary sections which are in direct communication with the intake of a suction pump and two or more secondary sections which communicate with the primary section or sections by way of narrow passages defined by internal partitions of the suction chamber so that a sheet which is advanced in the transporting plane to a position of register with the cover is attracted first to that portion or those portions of the cover which overlie the primary section or sections and thereupon to those portions of the cover which overlie the secondary sections. The number of primary and secondary sections which communicate with the intake of the suction pump is reduced when the apparatus is used for transfer of smaller sheets. The number of perforations per unit area of that portion of the cover which overlies the primary section or sections is greater than the number of perforations per unit area of that portion of the cover which overlies the secondary sections, and the combined cross-sectional area of perforations in communication with the primary section or sections is greater than the combined cross-sectional area of passages between the primary and secondary sections.

摘要： A photographic copying machine wherein any one of a series of masks, each having a differently dimensioned light-transmitting opening, can be placed onto a locating plate which supports a battery of fixedly mounted or mobile magnetic actuators for discrete electric switching elements. Each mask carries a different array of soft magnets which displace or otherwise influence a group of actuators so that the thus influenced actuators open or close the associated switching elements which adjust the exposure controls and/or another system of the copying machine in dependency on the size and/or shape of the opening in the selected mask. The soft magnets on each mask influence a different group (e.g., a different number) of actuators each of which is an H-shaped permanent magnet.

摘要： A device which removes dust and/or other impurities from photographic films, records or other data carriers has one or more brushes whose bristles sweep along the surface or surfaces of a data carrier while the data carrier moves relative to the bristles and/or vice versa. The electrostatic charge which develops as a result of frictional engagement between the data carrier and the bristles is led away by providing each brush with bristles at least some of which consist of conductive material and are grounded via electrodes which contact the tips of the bristles and/or by way of the core of each brush.
