electronic systems for noise reduction by sound signals radiated out-of-phase in noisy interiors whose major components are sensors for scanning the vibration as well as magnetic devices influenced by scanners, relays capable of producing counter vibration via a hydraulic fluid
Electrical and Scientific Apparatuscovers mounted on motors, namely covers for vehicle construction as well as covers on automotive bodies, namely insulating capsules in the form of structural parts such as hoods, all for sound absorbing purposes; covers and shields with or without sound absorbing lining for use as parts of vehicles, namely hoods; resiling crossings between cars, namely metal railcar knuckle couplers
Vehiclesinsulating products, namely membranes, double coated fabrics, rubberized fabrics for use in vehicle interiors and railway systems for insulation against sound, cold heat, shock, vibration, shaking, moisture and environmentally dangerous substances
Rubber Goodsprotective roofings made of fabrics and foams being coated and impregnated with bitumen or bituminous substances
Nonmetallic Building Materialscarpets for vehicles, namely, shaped or plain carpeting with flexible and/or still heavy coatings and with integrated dimensional foam articles for reducing noise
