  • Flexible armor
    Patent number: 4608717
    Abstract: A flexible protective armor has the form of a laminate having front and back layers of an aramid fibre fabric sandwiching a bag of packed feathers, foam, or felt material. The laminate is drawn tightly together by stitching or similar process. The armor may be further enhanced by integrating the laminate with a front shield of further layers of aramid fibres which are also stitched together.

  • Elongate structure
    Patent number: 4435242
    Abstract: A method of fabricating a tapered elongate structure in which a polygonal tube or channel cross section member is cut lengthwise and at an angle to its longitudinal axis to produce a plurality of similar segments of tapered shape. The segments are then arranged in an abutting or overlapping relationship and bonded together to form the tapered elongate structure.

  • Resin impregnator for filament wound pipe
    Patent number: 4361459
    Abstract: Apparatus for impregnating filaments with resin, suitable for use on fibre-reinforced pipe making machines, comprises:(i) a fixed annular guide (6) feeding the filaments onto a translating, or translating and rotating mandrel (D),(ii) an annular spinning disc (4) with means for rotating the disc (12), and(iii) means for feeding resing to the disc (4).The spinning disc feeds resin to the filaments in controlled amounts and avoids the use of porous guides or resin troughs.
