Title: Process and apparatus for manufacturing tube bends
Inventor: FERGUSON JAMES M
IPC: B21D9/12
Filed: 1987-08-12
Granted: 1992-07-14
Abstract: ABSTRACT          A process for making a tube bend comprises forming a straight tube of quasi-elliptical cross section with the portion of the tube wall on one side of the major axis of the quasi-elliptical cross section made of a non-constant thickness which is a maximum at the point where the Minor axis of the quasi ellipse meets the tube wall on one side of the major axis of the quasi ellipse, applying against the portion of the inner surface of the tube wall on the other side of said major axis radially directed expansion and bending forces of a magnitude sufficient to displace that portion of the tube wall away from said major axis to a position in which the tube has the required internal dimensions and shape of cross section and curvature of the bend to be formed.          Apparatus for performing the process includes a tube compressing die formed with an oblique passage and a curved expanding mandrel for expanding and bending the compressed tube.

Abstract: ABSTRACT            NON-LINEAR OPTICAL LOGIC GATE     An optical device comprises first and second optical waveguides (1,2) connected between respective output and input ports of first and second optical couplers (3,4). The first coupler has at least one input port and is adapted to couple optical signals received at the input port into its output ports in a predetermined coupling ratio.  The second coupler has at least one output port and is adapted to couple optical signals received at each input port (7,8) into its output port in a predetermined coupling ratio.  The first and second waveguides (1,2) define respective optical paths with substantially the same optical length.  The waveguides (1,2) are fabricated from materials which exhibit soliton effects when optical pulses, at working intensities, are injected into the waveguies, such that the pulse propagation is dispersion dependent, whereby the portions of an optical pulse received at the input of the first coupler (3) are coupled into the waveguides (1,2) by the first coupler and arrive sychronously but phase shifted relative to one another at the second coupler (4) after travelling along the waveguides.  The device may be configured to provide optical switching and logic functions.     Figure 1

Abstract: PROCESS AND APPARATUS FOR CONTINUOUSLY SHEATHING SOLID OR HOLLOW PROFILES, ESPECIALLY TUBES, WITH AN EXTRUDED FOAM JACKET OF THERMOPLASTIC SYNTHETIC RESIN, AND PRODUCTS THEREBY PRODUCED                   Abstract of the Disclosure A process and an apparatus for continuously sheathing solid or hollow profiles (1), especially tubes, with an extruded foam jacket (3) of thermoplastic synthetic resin is provided. To this end a foam jacket is ex-truded, slit open, and into the slit foam jacket (3) the solid or hollow profile (1) to be sheathed is con-tinuously coaxially introduced at synchronous speed. The slit foam jacket is closed by welding after the intro-duction. The process steps of slitting the foam jacket, introducing the profile to be sheathed into the foam jacket, and closing the foam jacket (3) by welding are to be carried out at temperatures of the foam Jacket above the glass transition temperature of the synthetic resin material of the foam jacket. After the slit in the foam jacket (3) has been closed by welding, the jacket cools down and snugly shrinks onto the profile to be sheathed. According to a further embodiment said foam jacket (3) can be additionally provided with a protective film skin (5) extruded thereon in order to thus increase the impact resistance, the scratch resistance, and the water vapor impermeability of the foam jacket (3).

Title: Recording system capable of recording a sequence of optimum coded signals on an rom
Inventor: KOGA TOSHIO
IPC: H04N5/92
Filed: 1988-04-29
Granted: 1991-04-02
Abstract: Abstract of the Disclosure:       In a recording system operable in response to a sequence of image signals to record a sequence of recording signals on a main image recording medium, efficient coding is carried out by the use of parameters which are adaptively changed from one to another through a parameter controller acting as a man-machine interactive device.  The image signals are repeatedly given to the recording system to be subjected to the efficient coding with reference to a sequence of predictive value signals V(i).  The predictive value signals are displayed on a monitor display device to be monitored by an operator.  The operator can change the parameters from one to another until an optimum image is displayed by the use of optimum parameters, watching the display device.  The optimum parameters are sent on a magnetic tape.  The image signals are subjected to the efficient coding into a sequence of coded image signals which are recorded on the main image recording medium in synchronism with the optimum parameters after the optimum image is obtained.

Abstract: ABSTRACT OF THE DISCLOSURE            In a toy vehicle track with toy vehicles having an electric drive motor disposed on the chassis and with a track formed in particular by segments which can be plugged together, the electric drive motor being supplied with electricity via collectors and conductors placed in the track, uninterrupted operation is ensured over a period of time of optional length when the connection with the mains supply fails or is terminated by providing the segments with conductors extending along the entire track.  The toy vehicle have collectors which are in contact with the conductors and a rechargeable power source serving as an electric buffer.  The power source and the collectors are simultaneously in permanent connection with the drive motor.  If the power supply is cut off from the mains, the internal power source is automatically activated and permits further operation until it becomes discharged.  The conductors on the segments are formed either by metal foil or metal foil segments, by electrically conductive pre-formed parts, clampingly clipped to the individual segments, which are either removably clippable to the edge members or on the segments in the area of the track surfaces, or they are irremovably fixed to the segments.
