Abstract: The quality of printed matter, which is one of several copies of the same printed matter produced by a printing machine, is evaluated. An amount of copies of the printed matter is selected from the total production of this printed matter. The selected amount of these copies are evaluated with regard to at least one error type which belongs to an amount of different error types or with regard to at least one feature of the error. Within the selected amount of copies, an error of a defined error type or of a defined feature, which is detected on at least one of the copies, is evaluated in relation to at least one error of another type or feature detected on the same copy, or another copy of the selected amount. The printed matter is classified as having good or bad quality based on that evaluation. A common reading, producing image data, is obtained by an image sensor from the selected copies.

Abstract: A method for extracting minerals from a narrow-vein deposit by thermal fragmentation is provided. The method includes locating the vein and determining the extent thereof to form the boundaries of a stope. Access to the stope is prepared by forming a panel having an upper drift and a lower drift. Equipment for thermal fragmentation, including a burner, is installed from the upper drift. The burner moves along the panel surface in a sweeping motion, while rock chips spalled from the rock panel surface are collected. Multiple panels for processing can be realised, with lower panels being processed before upper panels, by excavating a sub-level to separate the lower and upper panels.

Abstract: A system is provided for inspecting a printed image. The system is provided with at least one evaluation unit, a display device and an image scanner. That scanner takes an image that represents, at least partially, a printed image. The copied printed image belongs to a sequence of images printed on a print carrier by a printing machine. The evaluation unit receives data that is correlated to an image which has been taken, and evaluates that data by comparing it with recorded data of at least one preceding image, or with a reference image. The display device is provided with a graphic display surface that is comprised of several areas which are controlled, in a different manner, by the evaluation unit, and which are preferably simultaneously displayed. A first area displays several images, such as the just taken image, the preceding image and the reference image.

Abstract: A device is used for controlling an installation that is comprised of several units. A common control system, that is provided with a central data memory, in which current real values and/or set points are filed as process variables for several units, is allocated to several of these units. The data memory encompasses a storage area for the process variables. The data structure of this storage area can be configured even by using a set of data that describes the projected installation.

Abstract: A printing machine includes a printing cylinder that is fitted with plates for printing the width of N pages. A web of material is printed and is then cut longitudinally, by an elongate cutting device, into printed webs. The number N of pages is a whole number that is divisible by three and the total width of N pages is less than the width of the printing cylinder. A width of N+1 pages is greater than the width of the printing cylinder. The elongate cutting device can be arranged, on one boundary, between a Kth and a Kth+1 page, wherein k is one third or two thirds of N. At least one of the resulting partial webs is guided through a former. The former is oriented so that the direction of travel of the web entering the former is transverse to the direction of web travel in the elongated cutting device. The former has a width that is equal to, or greater than two thirds of the width of the printing cylinder, but is less than the entire width of the printing cylinder.

Abstract: A laser and electroabsorption modulator (EAM) are monolithically integrated through an etched facet process. Epitaxial layers on a wafer include a first layer for a laser structure and a second layer for an EAM structure. Strong optical coupling between the laser and the EAM is realized by using two 45-degree turning mirrors to route light vertically from the laser waveguide to the EAM waveguide. A directional angled etch process is used to form the two angled facets.

Abstract: A rotating element of a printing machine is connected to a rotation transmitter that is usable to introduce a liquid or a gaseous medium into the rotating element. The rotation transmitter includes a rotor that is rotatable with the rotating element, and a stator that is secured against rotation. At least one stator channel section cooperates with at least one rotor channel section to provide a fluid flow path for the medium into the rotating element. Axially oriented and mutually opposite contact surfaces, which are against one another when the liquid or gaseous medium is introduced into the rotating element of the printing machine, are provided on the rotor and on the stator.

Abstract: A device for coupling a driver system to a downhole string of sucker rods in a petroleum well employs a polish rod construction in which the polish rod is strengthened by an attached sleeve providing a transverse should in a predetermined plane. The sleeve is shrink fit in place and mechanically adhered to withstand the stresses and shocks encountered in long-term cyclic operation. The device provides specific benefits for an improved sucker rod connection which prestresses the sucker rod pin ends and the coupling in a fashion to resist the development of microcracks and fatigue failures.

Abstract: A printing plate is produced having at least one edge which has been cut so that it is parallel to a line of delimitation of the type area of the plate. The printing plate is fed to an impression cylinder of a printing press, in an axial direction of the impression cylinder by use of a plate feeding and alignment device. During the process of feeding the printing plate to the impression cylinder, the at least one edge of the plate, which was cut parallel to the type line of determination, is guided against at least one stop.

Abstract: A method is used for the early identification of a deviation in the printed images which have been formed by a printing press during continuous production. A second decision threshold is provided, in addition to a decision regarding good or bad print quality. A current printed image, that has been captured, is compared with a reference image. If the current image deviates from the reference image, that deviation is evaluated using two decision thresholds.

Abstract: A quantity of ink is dosed in an inking system of a printing machine, which inking system is provided with at least one dosing device that can be used to modify the quantity of ink which is transferred by the inking system. The dosing device can be adjusted by the use of an adjusting element to modify the quantity of ink that is to be transferred. A modification of the quantity of ink is defined by an adjustment of the adjusting element. The dosing device is adjusted in accordance with a pre-determined correlation between the amount of the adjustment of the adjusting device and the current state of the dosing device. The adjustment of the dosing device is carried out in accordance with the correlation in such a way that a relation between the modification of the quantity of ink caused by the adjustment of the dosing device, and the ink quantity transferred by the dosing device remains essentially constant.

Abstract: An optical system is usable for forming an illuminated pattern on the surface of a material which is being displaced with respect to that illuminated pattern. An illuminating device, which includes several light sources that are driven in a pulsed manner by a control unit, emits light that is used to form the illuminated pattern. A detection device detects the light emitted by the illuminating device. The control unit controls one individual light source, or a group of light sources. An operating time of the light source or sources is synchronized with an exposure time of the detection device. The operating time of the light source is shorter than the exposure time of the detection device.

Abstract: A printing machine utilizes several printing couples to produce at least one printed image on a printed material. Compensation for at least one of a longitudinal elongation and a transverse elongation of the printed material is accomplished. An anticipated elongation of the printed material is compensated for by matching of a printed image placement, with respect to length, width or position, with an imaging system generating the printed image placement on a printing form.

Abstract: A hybrid drive (HD) multi-mode pipe projector (MMPP) for use in underwater acoustic applications is provided. The HD MMPP is formed with an inner magnetostrictive drive motor nested within an outer drive motor. The inner motor is surrounded by a magnetic field generating coil winding. Preferably the inner drive motor is a Terfenol-D motor and the outer drive motor is a radially-poled piezoceramic drive motor. This nested configuration provides increased bandwidth and low-frequency extension to the MMPP design.

Abstract: A methodology for forming a composite color image fusion from a set of N gray level images takes advantage of the natural decomposition of color spaces into 2-D chromaticity planes and 1-D intensity. This is applied to the color fusion of thermal infrared and reflective domain (e.g., visible) images whereby chromaticity representation of this fusion is invariant to changes in reflective illumination.

Abstract: At least one of a transverse elongation and a longitudinal elongation of a printing material are compensated for. The printing material passes through serially arranged printing couples in a printing press. A component of the transverse elongation is compensated for after passage of the printing material through a first printing couple and before its entry into a second printing couple. This can be accomplished by the use of a framing controller. Alternatively, this transverse elongation can be compensated for by the displacement of at least one printing form which is situated on a subsequent printing couple. The printing form can be displaced transverse to a production direction of the printing material, relative to a reference mark on the printing material. An elongation of the printing material, which is known at the time of image generation on a printing form of a subsequent printing couple can be compensated for by proper configuration or positioning of the printed image on the printing form.
