Patent number: 7341574Abstract: A veterinary syringe comprises a base body for receiving a syringe barrel with a guiding element for a plunger rod that is guided therein so as to be movable in a longitudinal direction. At one end of the plunger rod, a plunger is attached that extends into the syringe barrel. The syringe further comprises a handle and an operating lever. The operating lever is connected to a guiding element that engages with a toothed rack associated with the plunger rod, and with a locking device for the plunger rod that engages with the toothed rack. The locking device acts as a locking slider disposed inside the guiding element and has an opening through which the plunger rod is guided and extends into the toothed rack from below, locking the toothed rack so as to prevent it from withdrawing.Type: GrantFiled: March 10, 2003Date of Patent: March 11, 2008Assignee: Henke-Sass, Wolf GmbHInventor: Karl Schreijag

Patent number: 7319478Abstract: A solid-state video camera is equipped with pixel addition logic such that, if the measured object brightness falls below a certain threshold value, a brightening of the image is effected without increasing the noise component accepting a loss in real-time representation. The pixel addition by way of the pixel addition logic is coupled to the gain control of the camera in a manner such that, in each case, the gain control compensates for jumps in brightness which arise by way of the pixel addition and creates for the user a flowing transition without noticeable jumps in brightness.Type: GrantFiled: April 4, 2003Date of Patent: January 15, 2008Assignee: Richard Wolf GmbHInventors: Martin Dolt, Michael Vögele
