Patent DE-3270343-D1 (DE)
Title: Endoscopes
Inventor: SHISHIDO YOSHIO
IPC: A61B1/04
Filed: 1982-01-28
Granted: 1986-05-15
Abstract: A hard endoscope which can be removably fitted with a photographing device in the eyepiece part and by which, for example, a body cavity in which it is inserted can be observed and photographed is disclosed. In the case of taking a photograph with a hard endoscope fitted with a photographing device in the eyepiece part, if the optical axis of the hard endoscope and the optical axis of the photographing device do not coincide with each other and are eccentric from each other, the image obtained in the photographing device will differ from that seen by the endoscope. Therefore, the hard endoscope of this invention is provided in the eyepiece part with an eccentricity controlling means which can center the optical axis of the hard endoscope to coincide with the optical axis of the photographing device.

IPC: B29C37/00
Filed: 1984-05-01
Granted: 1987-04-30
Abstract: An apparatus for cutting scrap tires and other waste products is disclosed. The apparatus includes a frame having a cylindrical anvil roll rotatably mounted therein. A pair of blade rolls are also mounted in the frame for rotation about corresponding axes which are parallel to the rotational axis of the anvil roll, the blade rolls being angularly spaced from one another relative to the axis of the anvil roll and being positioned about the periphery of the anvil roll. The blade rolls are each provided with a plurality of blades of predetermined diameter fixed thereto and rotatable therewith, the blades of one blade roll being at a low angle to the axis of that roll and the blades of the other blade roll being at a high angle to the axis of that roll, so that a tire passing between both blade rolls and the anvil roll will be cut into rhomboidal pieces that are nearly rectangular in shape during a single pass through the apparatus. The blade rolls are each also provided with a pair of axially spaced thrust wheels, with the thrust wheels being positioned outboard of the blades and being equal to or slightly greater in diameter than the predetermined diameter of the blades. Driving means are provided in the apparatus for rotating the anvil roll in one direction and the blade rolls in an opposite direction. Biasing means are also provided for forcing the outer peripheries of the thrust wheels and the anvil roll into hard contact with one another thereby to maintain fixed the spacing between the cutting surfaces of the blades and the outer surface of the anvil roll notwithstanding the separating forces caused by the movement of a tire between such surfaces.

Abstract: In a first measuring phase the values derived from unfiltered light from the exposure light source are stored. In a second measuring phase these values are combined with the continuously measured values derived as the colour filters are moved into their effective positions. The filtering is regulated in dependence upon the combined measurement signal. A degree of colour under-correction, which can be predetermined, results from the combination of the measurement signals from both measuring phases. A flat housing (1) encloses the main parts of the measuring circuit. The upper covering surface (2) is separated into an incident light area (3) and a display and operating area (4). The light area has openings (5,6,7) for red, green and blue sensitive photoelectric transducers.

Abstract: Use of intaglio printing cylinders consisting of a core of a virtually non-deformable material and a detachable multi-layer sleeve secured to the core has shown that they are not able to withstand all the strains of a heavy-duty printing plant and that the special equipment necessary for their treatment is operationally unsatisfactory. The new intaglio printing cylinder is intended to be an improvement with respect to its operational properties and, in particular, to have a longer working life and to be capable of use and operation in conventional solid-metal intaglio printing cylinders. The new intaglio printing cylinder is distinguished by the fact that a number of ribs (41) running essentially in the longitudinal direction of the cylinder (1) are arranged on the outer face of the first, inner layer (4) of the sleeve (3) so as to project outwards. This intaglio printing cylinder possesses improved stability, especially against rotation or displacement within the sleeve in the circumferential direction and, consequently, has a longer working life. A further improvement in its operating properties is achieved by means of a direct electrical connection between the core and the outer copper layer. The new intaglio printing cylinder is particularly suitable as a replacement for the solid-metal printing cylinders still in use today. It offers the advantage that a number of different sleeves with different external diameters can be used with a single core. <IMAGE>

Granted: 1993-04-01
Abstract: The rotor of a driving device comprises an output shaft with transmission wheels fixed on the output shaft. The rotor is provided with rotor bodies and a transmission device which is interlocked with the transmission wheels. Each rotor body is equipped with rotating body parts on a support shaft in a free rotatable manner.  Balance bodies are attached to these rotating body parts through pins located at eccentric position of these balance bodies in a manner to provide free rotation. Crank bodies, driven by the rotating bodies, are freely-rotatably equipped on the support shafts.  Where the output shaft rotates by an input from an external source, the rotating bodies also rotate at the same time. The balance bodies also rotate in association with the rotation of these rotating bodies.  The crank bodies prevent a state that parts of the balance bodies protrude outwardly from the rotating bodies. Thus, the inertial force of the rotating bodies is ensured.
