  • Patent number: 5633434
    Abstract: Virus genes, for example coat protein genes, which bring about a reduction in the signs of infection by the corresponding virus or bring about virus resistance can be combined with herbicide-resistance genes for the transformation of plants.A combination of this type facilitates the selection of the transgenic plants. In addition, in practical field cultivation, the vitality of the plants is increased by the virus tolerance, and an improved plant protection is possible owing to the herbicide-resistance gene.

  • Patent number: 5628045
    Abstract: A process for producing sintered parts with high wear resistance and good dynamic strength properties from formed bodies, which have been pressed as green parts from a completely-alloyed air-hardened heat-treatment steel powder with a carbon content of at least 0.3% added in the form of graphite. The process includes sintering the parts under protective gas at a sintering temperature of at least 1000.degree. C. and subsequent cooling. The sintered parts are cooled immediately after sintering from the sintering temperature to a first holding temperature in the range of Ar.sub.3 to a maximum of 150.degree. C. above Ar.sub.3 and are held for a first holding period of 5 to 25 minutes at this temperature (austenitizing phase). Immediately after this, the sintered parts are cooled in accelerated fashion to a second holding temperature by convective gas cooling and are held at this temperature for a second holding period.

  • Patent number: 5627354
    Abstract: A stack of individual sheets of film is enclosed by lightproof plastic packaging. An opaque sheet is disposed at the bottom of the stack, and the side of the opaque sheet confronting the packaging is provided with a bar code containing information about the film. The packaging is removed in a lighttight area of a processing unit for the film and the bar code is read. The opaque sheet prevents the radiation used to read the bar code from reaching the film. The information retrieved from the bar code is employed to control processing of the film.

  • Patent number: 5383979
    Abstract: In a process for producing a workpiece from sintered metal, especially from sintered iron, the latter is subjected, after sintering, to a steam treatment at temperatures below 500.degree. C., especially at 430.degree.-480.degree. C., at a steam partial pressure of from 20 to 80 mbar, especially from 30 to 50 mbar, to form an oxide layer on the surface, and to subsequent surface-hardening. Workpieces, especially internally geared wheels for starters, having a wear-resistant surface and, in the core, properties unchanged by the hardening are obtained.

  • Patent number: 5334964
    Abstract: A device having cores of metal oxide ceramic (for example, Y-Ba-Cu-O) for limiting a short circuit current in power supply systems. The concept provides that a choke core, when operated at a rated current, is superconductive and its shielding currents keep the resulting inductance in the choke at a low level. In the event of an overload, the winding of the choke generates a correspondingly high magnetic field in the core which puts the core into the normally conducting state. This causes the shielding currents to disappear in connection with a rise in the resulting inductance, thus limiting the current. In order to realize a particularly high inductance in the normally conductive case, the superconductive choke core may be made hollow and may be filled at least in part with a ferromagnetic material.

  • Patent number: 5134346
    Abstract: The driving apparatus for the rotation of the spindle or the work piece pallet of an electroerosive machining device comprises two electric motors which drive e.g. the spindle to a rotational movement by means of two gear boxes and a plurality of gear wheels. In order to avoid any backlash in the gear box and any clearance between the gear wheels and to compensate the elasticity of the gear transmission, the two electric motors are always operated to rotate in opposite directions and/or to yield different values of torque. Thus, the entire transmission assembly is always subjected to a certain bias force so that a precise positioning of the spindle is possible by means of simple and inexpensive driving elements.

  • Patent number: 5115898
    Abstract: The spreading apart and keeping apart of the individual disks in friction disk sets or clutches and/or brakes makes it possible to avoid drag torques and the losses of energy caused thereby. Spreading elements, in the form of magnetic bodies (8), which are inserted in disk carriers (1, 10) radially with respect to magnetizable marginal zones of the disks (4, 13) lead to equal polarity in the marginal zones concerned. A reciprocal rejection force of the individual disks (3, 14) in axial direction thereby results. Since the magnetic bodies (8) are firmly introduced in the disk carriers (1, 10), interruptions in operation and difficulties in assembly, the same as special processing of the disks, are avoided. The spreading forces themselves remain equal independently of the position and the speed. When electromagnetic coils (8A) are used, the spreading force can be switched off, for example, when actuating the piston (19) and thus the piston force is kept small.

  • Patent number: 5074731
    Abstract: The invention provides a screw nut comprising a central inner thread and a radially extending slit, the width thereof essentially corresponding to the diameter of the central inner thread. Thus, a threaded bolt or a threaded stud can be radially inserted into said screw nut body. In order to avoid that the screw nut is displaced away from the threaded bolt or stud during tightening of the screw nut, the central inner thread comprises a plurality of thread turns provided with axially extending recesses directed towards the end surface of the screw nut which is under load when the screw nut is tightened on the threaded bolt or stud.

  • Patent number: 4965455
    Abstract: An x-ray film has a flexible sheet having a front face and a rear face, a layer of an x-ray stimulable phosphor on the front face, and a layer of mangetically attractable material, for example a steel foil, on the rear face. This film is used with a film handling apparatus, normally a reader, having structure forming a flap support surface of a size at least equal to that of the film and at least one permanent magnet is imbedded in the structure and extends over the surface. Thus the rear face of the film can be adhered magnetically to the surface. An array of stripping elements is distributed over the surface and each element is displaceable through the surface between a recessed position below the surface and an advanced position projecting past the surface. An actuator can displace the elements from their withdrawn to their advanced position and thereby lift from the surface a film clinging magnetically to the surface.

  • Patent number: 4790078
    Abstract: The measuring apparatus comprises a base plate member including a rotatable measuring object receiving station adapted to rotatably receive e.g. a tool to be measured. Besides the receiving station, a guiding column is arranged having a guiding rail along which a measuring carriage is movable upwardly and downwardly. The carriage is provided with a horizontally displaceable measuring rail, an end portion thereof being equipped with a measuring calliper assembly. This assembly includes a measuring calliper with a calliper head which may be brought into contact with the tool to be measured. The calliper head is displaceable with regard to a calliper portion fixed to the end portion of the measuring rail. A force acting on the calliper head in horizontal direction (e.g. towards the right) causes the same displacement of the calliper head as a force acting on the calliper head in vertical direction (e.g. upwardly). The displacement is determined by means of a measuring gauge.
