Abstract: An endoscope for laparoscopic surgery, including a shaft with a central axis, a proximal end, a distal end and a first optical beam path with a prism at the distal end of the shaft and having light entrance and exit surfaces, a lens with an optical axis, the lens behind the prism considered from the distal end of the shaft, and beam deflecting optics behind the lens considered from the distal end of the shaft. The light entrance surface is oriented perpendicular to the central axis, and the light exit surface forms a first angle of inclination with a first spatial axis oriented orthogonal to the central axis. To increase the numerical aperture of the lens, the optical axis is arranged perpendicular to the light exit surface of the prism. As a result, the lens has a cross-sectional area that is larger than the light entrance surface of the prism.

Abstract: A device for pushing glass objects onto a conveyor belt includes a pusher (5), which is supported on a crank arm (6) in such a way that it can be swiveled about an axis (7), which crank arm is in driving engagement with a first electric motor (1) by means of a shaft (12). A second electric motor (2) is in driving engagement with a sleeve (20) by means of a cantilever (18), in which sleeve the shaft (12) is mounted, wherein the shaft (12) can be swiveled about a central stationary axis (19). A third electric motor (3) is arranged to rotate the pusher about the axis (7).

Abstract: A device having a pusher for pushing glass objects from a resting plate to a conveyor belt moving at a uniform speed. The device has first, second and third electric motors, the first motor mounted to be stationary, and the second and third motors being moveable relative to the first motor. The three motors are connected to the pusher via various transmission parts and controlled independently for controlling the motion of the pusher.

Abstract: The invention relates to a device for pushing glass objects from a resting depositing plate to a conveyor belt moving at a uniform speed, characterized by a first electric motor (1) arranged in a stationary manner within a housing (49). The electric motor has a driving connection to a cantilever (4) that is rotatably supported about a vertical axis (8). An accommodating element (9) is located on the cantilever. The accommodating element carries a second electric motor (12), the output shaft of which extends vertically and is connected at the free end thereof to a crank arm (17) in a rotationally fixed manner.

Abstract: An apparatus for pushing hollow glass articles from a depositing plate of an IS glass molding machine onto a belt conveyor comprises a transfer pusher (11), one end of which is rigidly connected to a vertical shaft (10) and the other end of which carries an arrangement of pushing fingers for the glass articles. The shaft (10) is supported in a rotary table (6) and functionally connected to a first rotary drive (13) carried by the rotary table while the rotary plate (6) is mounted on a bell-shaped bearing (24) supported on a console (1) by means of a hollow shaft (22), namely such that it is functionally connected to a second rotary drive (15?). An approximately exponential transfer curve of the pushing fingers that begins at the depositing plate and ends on the belt conveyor and subjects the hollow glass articles to the least possible stress can be realized.

Abstract: An apparatus intended for pushing hollow glass articles from a depositing plate of an IS glass moulding machine onto a belt conveyor that moves rectilinearly at a uniform speed comprises a transfer pusher (11), one end of which is rigidly connected to a vertical shaft (10) and the other end of which carries an arrangement of pushing fingers (12) intended for contacting the hollow glass articles to be pushed. The shaft (10) is supported in a rotary table (6) and functionally connected to a first rotary drive (13) carried by the rotary table while the rotary plate (6) is mounted on a bell-shaped bearing (24) supported on a console (1) by means of a hollow shaft (22) extending parallel to the axis of the shaft (10), namely such that it is functionally connected to a second rotary drive (15?).
