Patent number: 4450767Abstract: Disclosed is a control system for an ink blade of a printing machine provided with a series of key setting units each having a key position sensor and a key drive controlled by an adjusting device described in patent application Ser. No. 252,126. In order to achieve proper adjustment of marginal key setting units, there is provided a switching unit with a plurality of contacts assigned to respective key position measuring sensors and including additional switching contacts assigned to imaginary key position setting units adjoining the real setting units at each end of the ink zone. The additional marginal switching contacts are connected to the output of assigned sample-and-hold members which apply thereto the measured value from the extreme actual position sensors so that comparing differential transducer comparing the measured values of consecutive pairs of position sensors always produces a starting difference which does not exceed a predetermined limit value.Type: GrantFiled: January 20, 1983Date of Patent: May 29, 1984Assignee: VEB Kombinat Polygraph "Werner Lamberz" LeipzigInventors: Karl-Heinz Forster, Hans Johne, Helmut Schuck, Ludwig Friedrich

Patent number: 4101812Abstract: An automatic flash-limiting arrangement for use in combination with a flash unit associated with a camera and arranged to automatically terminate the light flash produced by the unit when the subject has been properly exposed, the flash-limiting arrangement being associated with the flash unit so as to become operative only upon initiation of a light flash, thus assuring that the arrangement will not respond to extraneous flashes occurring before the flash which is to be controlled. The flash-limiting arrangement is constructed to sense the light being received by the camera, to produce a signal which is the sum of a component proportional to the time integral of the intensity of such light and a component which is proportional to the instantaneous amplitude of the intensity of such light, and to terminate the flash when this signal reaches a predetermined value.Type: GrantFiled: December 30, 1968Date of Patent: July 18, 1978Assignee: Metz ApparatewerkeInventors: Ludwig Friedrich Muller, Adolf Schott, Wolfgang Pecher
