摘要： A device for use in connection with an electronically controlled photographic printer is described which singles out from an advancing band of original copies those which are unsuitable for reproduction. The device includes a splice sensor for indicating the end or the beginning of an order, a sensor of individual pictures in each order, and a quality (sharpness) sensor. A resettable counter is connected to the splice sensor and to the picture scanner to produce an output pulse after a predetermined number of pictures or after the beginning or end of the order. The output pulse is applied to a selection logic circuit which has adjustable sensitivity levels. The selection logic circuit is controlled by the quality sensor to produce a "print" or "non-print" output pulse applied to the printer-controlling electronics. The output pulse from the counter is controlled by switching means to adjust the sensitivity level in the selection logic circuit so as to either ignore the signals from the quality sensor or to adjust the selection circuit to a lower sensitivity for responding to the quality signals.

摘要： Apparatus for convoluting a web of photographic material onto a rotary core in a lighttight cassette has an elongated channel which is pivotably mounted in the cassette and whose outlet is normally tangential to the peripheral surface of the core. The outlet of the channel is detachably or permanently connected with a flexible or deformable strip-shaped element in the form of a link chain, plastic band, textile band or metallic band which surrounds a substantial part of or the entire peripheral surface of the core. When the leader of a web is introduced into and advanced beyond the outlet of the channel while the core rotates in a direction to convolute the web, the foremost part of the leader penetrates between the core and the flexible element and adheres to the peripheral surface of the core not later than upon the making of approximately two convolutions. During winding, the flexible element insures that the neighboring convolutions of the web on the core are tightly packed against each other. When the web is being withdrawn, the flexible element brakes the web and prevents clockspringing of convoluted material.

摘要： Successive frames of a web of photographic color film are subjected to objective examination during transport through an automatic evaluating circuit which may constitute a discrete prereader or a prereader which is integrated into a copying machine upstream of the copying station. The prereader furnishes signals which represent color and/or density correction data for reproduction of those film frames which can be properly copied only with a setting of exposure controls which deviates from the average setting for copying of the majority of film frames. The objective examination of all film frames is followed by a subjective examination which is performed by an attendant who inspects at least some of those film frames whose examination by the prereader resulted in the generation of correction signals. The attendant inspects the film frames at the copying station or at a second station which is located immediately downstream of a discrete prereader, and the attendant simultaneously observes the corresponding correction signals which are furnished by the evaluating circuit and are displayed close to the copying station or in register with film frames at the second station. The attendant can approve, modify or cancel the correction signals, and can also initiate the generation of additional signals, e.g., to identify those film frames which are unfit for copying.

摘要： An automatic prereader for exposed and developed frames of a web of spliced-together photographic color films is preceded by a first station and followed by a second station at the first of which groups of successive frames are subjected to a first subjective examination by an attendant and at the second of which some of the frames are subjected to renewed subjective examination by the same attendant. The attendant actuates one or more pushbuttons upon examination of frames at the first station to produce signals which denote improperly oriented frames, frames which were exposed in artificial light and/or frames which are unfit for copying. Such signals are used to modify signals which are furnished by the automatic prereader. The modified and unmodified signals which are furnished by the prereader are examined for intensity, and those signals whose intensity is outside of a preselected range are displayed at the second station so that the attendant can observe such signals simultaneously with observation of the respective film frames and is in a position to initiate the generation of additional signals which are used to modify or erase the corresponding signals from the prereader before the signals are transmitted to the exposure controls of a copying machine.

摘要： Apparatus for splicing exposed photographic films to each other and to flexible threading tape has a housing defining a dark chamber, a splicer which is installed in the chamber, advancing rolls which transport the leaders of films and tape into the range of and beyond the splicer, a knife for the tape, and punches which apply holes into the tape ahead of and behind the knife. The holes which are punched into the leader of the remnant of severed tape are detected by a first photoelectric cell which is located ahead of the splicer whereby the cell arrests the advancing rolls for the tape to insure that the leader is located in an optimum position for splicing to the trailing end of the preceding film. The holes which are punched into the trailing ends of severed tape portions are detected by a second cell which is located behind the splicer and serves to arrest the advancing rolls for a severed tape portion so that its trailing end is held in an optimum position for splicing to the leader of a film. The cells also monitor the films which are formed with holes similar to those in the tape. When a web of end of the rearmost film, is to be removed from the apparatus, the attendant severs the tape in a region close to the outlet of the housing. The leader of the remnant of tape is held by a blocking device in an optimum position for attachment to the core of a fresh reel for one or more webs of spliced-together films.

摘要： A method, and an apparatus for carrying out the method, for purifying exhaust gases from internal combustion engines is provided. The engines having a catalyzer system which includes a first catalyzer and at least one second catalyzer, arranged downstream of the first catalyzer, for the conversion of HC, CO and NO.sub.x exhaust gas constituents. Exhaust gases flow through both catalyzers during the entire operating period of the engine. The first catalyzer is suitable for at least the catalytic conversion of HC and CO exhaust gas constituents. In a first step of the method, the first catalyzer is operated over-stoichiometrically during the cold starting phase in order to reduce the HC and CO emissions and, in a second step of the method with .lambda.-controlled stoichiometric exhaust gas composition, the catalytic conversion of the exhaust gas in the first catalyzer is at least largely de-activated and takes place in the second catalyzer. Substantially better endurance of the first catalyzer is attained for the same good reduction in the exhaust gas pollutants.

摘要： An exhaust-gas filter, for example a soot-particle filter, has a filter element which has inlet passages for the raw gas and outlet passages for the clean gas. In order as far as possible to prevent clogging of the filter over the running time caused by deposits on the filter walls, the raw-gas passages are configured with a larger cross-section than the clean-gas passages.

摘要： An exposed and developed filmstrip and band of similar length are connected edge-to-edge. An address for each negative of the filmstrip is imprinted on the band in the form of a bar code adjacent to the respective negative. The negatives are scanned and exposure values are calculated for the negatives from the resulting data. The exposure values are used to make proofs, and the exposure values for each negative are then stored in a memory under the corresponding address. When an order for final copies of a particular negative is subsequently received, the address of the negative is read from the band and used to retrieve the respective exposure values from the memory. The final copies are thereupon made based upon the retrieved exposure values.
