Title: Heat and sound insulation for exhaust pipes - expanded mica in double walled pipe resists heat and corrosion (SW 16.5.77)
IPC: F16L59/04
Filed: 1976-10-20
Abstract: The thermal and acoustic insulation material contained in the jacket of an I.C. engine exhaust pipe is of expanded mica. The expansion of the mica is achieved by high temp. thermal shock, during which all water contained is eliminated, leaving a very light heat and corrosion resistant material. The exhaust pipe is formed as a double walled tube, the ends of the outer being bent inwards and welded to the inner. The space between is packed with the expanded mica and for increased sound absorption, the inner tube is perforated and the thickness of the jacket increased. Very high temp. are resisted by the mica and the insulation can be applied close to the engine, assisting any post combustion. The mica may be retained in a mineral or hydraulic matrix.

Title: Implantable pyrolytic carbon electrode - uses thin layer of carbon activated by heating in air and deposited on core material
IPC: A61B5/0408
Filed: 1977-03-25
Abstract: The surface layer of pyrolytic carbon is not less than 0.05 mm thick. The whole electrode may be made of carbon or the surface layer may be deposited on a core of some other conducting material.
