Abstract: A device is provided for trimming an edge of printed products which are fed continuously at regular distances to a conveying arrangement. The conveying arrangement includes circulating, pocket-like conveying units that are loaded from above with printed products. The edges of the printed products project at the conveying units so that the edges extend through a cutting arrangement laterally disposed at the conveying arrangement and including a blade. A support arrangement includes a shoulder disposed on a rear side of the printed product relative to the blade. The support arrangement is set back from the projecting edge of the printed product and is disposed opposite the blade during the cutting process. The support arrangement is movable into position at least approximately over a length of a cut by the blade and is driven in the same direction and at the same cadence as the printed products that are fed to the cutting arrangement.

Abstract: A method is provided for controlling an electromagnetic actuator having an electromagnet including a magnetic core presenting a pole face and an electromagnet coil wound around the magnetic core, a return spring and an armature connected to an actuation mechanism and movable toward the pole face by a magnetic force of the electromagnet against the force of the return spring. The method includes: detecting a time behavior and/or value of current and/or voltage present at the electromagnet coil during a time period when the armature does not move relative to the electromagnet, and deriving a value corresponding to the actual ohmic resistance and/or inductance of the electromagnet coil from the detected time behavior and/or value from the detecting step for compensating changes in the ohmic resistance of the electromagnet coil.

Abstract: A magnetic disc recording and/or reproducing apparatus in which a magnetic disc cassette containing a magnetic disc provided with a center hub is loaded so that the center hub engages with a rotary shaft of a disc rotating motor to rotate the magnetic disc. A cam for displacing a magnetic head is fitted to the outer periphery of a boss supporting a bearing which supports rotatably the rotary shaft, so that the force from the cam can be transmitted to the magnetic head through a bearing utilizing the rotational movement having a high transmission efficiency. As a result, a pulse motor for displacing the magnetic head can be made compact in size and light in weight and the power consumption of the pulse motor can be reduced. The cam is interposed between the level of the magnetic head and the chassis and the rotary shaft of the disc rotating motor is used also as the rotation center for the cam via a bearing mechanism, so that the magnetic head can access any position.

Abstract: A method of making a cylinder liner for an internal-combustion engine includes the steps of applying a liner material to an outer cylindrical surface of a mandrel by thermal spraying for forming a coherent cylindrical sleeve on the mandrel; and removing the cylindrical sleeve from the mandrel. The cylindrical sleeve constitutes the cylinder liner.

Abstract: A process for the analog/digital conversion of an electric signal as well as a device for implementing the process is described. The process according to the invention provides that the time (T.sub.H, T.sub.L) be determined, which, starting from a voltage (U.sub.X) to be converted is necessary to charge up a RC component (10, 12) to a predetermined reference voltage, for example a switching threshold (S.sub.H, S.sub.L) of a comparator (14) or to discharge it. The device according to the invention provides that a selector switch (13), the comparator (14) as well as a time detector (15) are components of a microprocessor (17), which is wired with the RC component (10, 12) as well as with an input resistor (11) if necessary. The process according to the invention as well as the device according to the invention are particularly easy to realize and are suitable for use especially with a microprocessor (17) which does not have an integrated analog/digital converter.

Abstract: A propellant igniter assembly includes a housing having ignition channels for the passage of an ignition flame through the housing; an igniter part accommodated in the housing; and a booster part accommodated in the housing and frontally adjoining the igniter part. The booster part has a booster charge which includes a first partial booster charge adjoining the igniter part and composed of a readily ignitable substance and a second partial booster charge adjoining the first partial booster charge and being separated thereby from the igniter part. The second partial booster charge entirely obturates all the ignition channels. The second partial booster charge has a burning behavior and a mechanical stability such that the ignition channels remain obturated for a short duration even after ignition of the second partial booster charge, whereby a firing impact is first retained in the booster part and is subsequently abruptly released in a concentrated form through the ignition channels.

Abstract: A method of analyzing an amplified gene, including determining its copy number, involves subtractive hybridization of two cDNA libraries, one from the tissue of interest and the other containing biotinylated cDNA from normal tissue, where the annealed cDNA is removed by means of magnetic beads coated with streptavidin or avidin. The cDNA isolated after subtractive hybridization represents amplified DNA, and it is analyzed to determine what gene(s) were amplified. Furthermore, the copy number of the gene(s) can be estimated. The copy number thus determined can be correlated to the severity of a pathogenic state, to its prognosis, or to treatment efficacy.

Abstract: A method and apparatus for separating a material disposed inside a metal casing from the metal casing. A composite is provided including the metal casing and the material disposed inside the metal casing. An electrode system distinct from the metal casing is arranged inside a liquid. A high energy pulse is generated on the electrode system through spark discharge in the liquid thereby generating a pressure pulse. The material disposed in the metal casing is separated from the metal casing by effecting an absorption of the pressure pulse by the composite thereby breaking up the material.
