  • Patent number: 4964221
    Abstract: A coordinate-measuring instrument has a purely mechanical device (14) to compensate for the weight of a vertically displaceable spindle (9). The compensation device consists of a helical-coil spring having a working range which is small as compared with its length in relaxed condition, and a belt transmission interposed between the spring and the spindle (9). The belt transmission is preferably developed in the manner of a block and tackle. A first or drive pulley engages and drives the belt for Z-axis positioning of the spindle, and a second or belt-tension pulley applies weight-compensating tension to the belt.

  • Patent number: 4470679
    Abstract: On professional camera shutters, with an objective comprising a lens system defining an objective light passage, and a polygonal diaphragm, the leaves of which can be actuated by means of a diaphragm actuator control curve cam and in turn be pivoted out of the shutter light passage by means of a steeply ascending cam curve portion, precautions have already been taken to allow adaptation to the given conditions of different shutter objective combinations. These include equipping the diaphragm actuator with an adjusting slide serving to limit the setting range and provided with a scale pointer, and equipping the shutter with a diaphragm scale which is adapted both to the shutter passage size and to the f-number of the objective and which can be attached only when a decision has been made on the combination of the shutter and objective.

  • Patent number: 4372662
    Abstract: Diaphragm setting device for a photographic camera lens shutter, which comprises an elongate carrier mounted on the outer periphery of the shutter housing and a movable slider operatively connected to the diaphragm adjusting ring of the lens shutter, such that the slider is displaceably supported and guided on the carrier and has a scale corresponding to diaphragm settings, whereby, e.g. manual, displacement of the slider causes the diaphragm adjusting ring to adopt the setting indicated on the slider scale. The carrier and slider of the diaphragm setting device may be attached to the shutter housing, advantageously either by means of screw fastenings or by means of a quick attachment and release plug arrangement, i.e. at an exterior location on the front rather than on the rear of the shutter housing.

  • Patent number: 4354753
    Abstract: Reflex camera having a focal plane shutter in the camera body and a time adjuster associated with the focal plane shutter, and an interchangeable variable central shutter objective and a time adjuster associated with the central shutter, the focal plane shutter adjuster having a setting position "C" (central shutter) in which the central shutter of the objective can be used for exposure settings, and the objective shutter adjuster having a setting position "F" (focal plane shutter) in which a lock is operated to block the closure drive of the shutter segment system of the central shutter so that the focal plane shutter can be used.

  • Patent number: 4349256
    Abstract: A photographic camera having an objective incorporating an electrodynamic driving system for the diaphragm system, and also having a selector adjustable for a manual or automatic mode, in which the driving member for the diaphragm blades has a path limiting stop associated therewith which is selectively variable in its basic position by a manually operated diaphragm preselector ring, and which stop, in the manual mode, cooperates with a counterstop pin on the driving member to determine the correspondingly manually preselected position of the diaphragm blades, e.g. following shutter release on a camera with full aperture viewing, but which stop, in the automatic mode, is not utilized.

  • Patent number: 4339192
    Abstract: Cable release arrangement which is connectable to the shutter of a camera, comprising two flexible power transmitting members which are provided, at one corresponding end, with an actuating handle formed as a common housing, and, at the other corresponding end, with a threaded connection, one transmitting member being used to release the shutter and the other transmitting member being used to actuate the diaphragm blades and/or the shutter segments for the purpose of viewing through the camera shutter, wherein the transmitting member for effecting shutter release is actuatable by direct finger pressure upon an axially displaceably mounted push rod therefor, whereas the transmitting member which acts upon the diaphragm blades and/or the shutter segments is actuatable indirectly by way of a switching device which progressively displaces its axially displaceably mounted push rod, and wherein the corresponding end pieces of the two transmitting members which guide the rods respectively, are combined in said housi

  • Patent number: 4062030
    Abstract: Interchangeable lens retaining means for photographic cameras, so designed that the interchangeable lens may be placed on or removed from the camera by a simple axial movement in the direction of the optical axis, without requiring the rotational or twisting movement required when a conventional bayonet type mount is used. Shoulders on the interchangeable lens are engaged by a plurality of pivoted latches on the camera, the parts being beveled so that the latches are automatically thrust aside as the interchangeable lens is brought toward its seated position on the camera, and then snap behind the retaining shoulders on the lens. The latches are coupled to each other so that all move in unison. A radially movable button on the lens operates a lever to disengage all of the latches on the camera, so that the lens may be removed axially from the camera.

  • Patent number: 4051495
    Abstract: A photographic camera of the single lens reflex type, having provision for interchangeable lenses. Whenever a lens is not fully and properly engaged with and seated on the camera, the image on the focusing screen is blurred or altered from the normal image in a way to attract the attention of the photographer, so that he can make immediate correction before losing the opportunity to take the picture he wants.
