  • Preparation of laminated sheets
    Patent number: 5824178
    Abstract: A process for making a laminated sheet by cutting a fiber-reinforced thermoplastic resin sheet into a plurality of cut sheets. The cut sheets are feed to a butting apparatus to bring adjacent end faces of the cut sheets against each other. The abutted cut sheets are joined to a continuous sheet, which is a fiber-reinforced thermoplastic resin sheet, by melt welding using a heated roller where the cut sheets and the continuous sheet cling to the heated roller. Cooling of the joined cut sheets and continuous sheet occurs by causing such to cling to a cooling roller. A correcting roller is moved along the cooling roller, where the joined cut sheets and continuous sheet are between the cooling roller and the correcting roller, so that the amount of contact arc between the joined cut sheets and continuous sheet is changed to adjust the amount of warp in the joined cut sheets and continuous sheet.

  • Apparatus and method for digital video and audio processing a plurality of pictures and sounds
    Patent number: 5502512
    Abstract: An apparatus for digital video and audio processing including information input and output processing devices for input, output, and processing of pictures and sounds. An information transmission device is provided for transmitting video and audio information between adjacent information input and output processing devices in one direction. The information transmission device connects the information input and output processing devices to a control device which controls the information input and output processing devices. A bus is also provided for transferring video or audio information or control information to the information input and output processing devices. An input terminal is used to enter control information into the control device.

  • Catalytic preparation of polyamide or polyamide-polymide with N,N'-dimethyl alkylene urea solvent
    Patent number: 4795795
    Abstract: A polyamide and/or polyimide is prepared by using N,N'-dimethylethyleneurea or N,N'-dimethylpropyleneurea as a solvent upon polycondensation of a polycarboxylic acid and a diisocyanate at a temperature above 100.degree. C. in the presence of an alkali metal carbonate, alkali metal hydrogencarbonate, alkali metal hydroxide or an alkali metal salt of a polycarboxylic acid.

  • Process for the preparation of polyamide compounds by the reaction of polycarboxylic acids with diisocyanates in the presence of at least one mono-alkali metal salt of dicarboxylic acid
    Patent number: 4395531
    Abstract: Disclosed is a process for the preparation of polyamide compounds by reacting at least one polycarboxylic acid with at least one diisocyanate in the presence of a catalyst comprising at least one mono-alkali metal salt of dicarboxylic acid. The polyamide compounds prepared by this process have a substantially linear configuration and a high degree of polymerization and, therefore, are suitable for the manufacture of fibers, films and molded articles.
