  • Patent number: 4997705
    Abstract: A laminate acoustic window for sonar systems having a pair of septa sandwiching a core therebetween, the core being made of a low shear high elongation to break material, the septa being formed of a relatively low density, high modulus material. The windows of the invention are characterizied by unusual freedom from attenuation loss over a wide frequency range. The windows are further substantially self damping and avoid thereby a generation of significant quantities of deleterious noise due to self generated vibration and transmitted vibration.

  • Patent number: 4847331
    Abstract: A composition of matter comprising a blend of CPVC having a chlorine content of between about 60% and 66% by weight and a polymethylmethacrylate content of between about 0% and 80% by weight of the blend. The composition of matter displays substantially single, homogeneous phase behavior with the CPVC and polymethylmethacrylate being substantially or completely miscible. Blending of CPVC and polymethylmethacrylate provides a reulting blended polymeric material having enhanced temperature and durability properties. Melt processability of CPVC polymeric material may be enhanced by the inclusion of polymethylmethacrylate to form the blends.

  • Patent number: 4822239
    Abstract: A vertical axis windmill wherein the blades pivot between a power delivery and a recovery position with air gates associated with a non-rotating chamber containing the windmill acting to preclude airflow over the blades while in the recovery position. The blades either include chambers therein configured to receive a fluid moveable between the chambers as dictated by rotational speed of the windmill, or the blades are connected in pairs with elevational motion of one blade to a power delivery position assists the other blade of the pair in returning from the power delivery position to the recovery position.

  • Patent number: 4820753
    Abstract: A sonic window suitable for use in sonar applications wherein an elastomer such as natural or synthetic natural rubbers, a low air entrapping fiber or fibril used for reinforcement, fillers, and thermosetting resins are formed into desired window configuration. The low air entrapment associated with the fiber or fibrils produces a remarkably sonicly transparent window.

  • Patent number: 4760483
    Abstract: In a circuit having an electro-mechanical relay, the contacts of which are subject to arcing, bridging across the electro-mechanical relay in a manner configured to begin conducting electrical current around the electro-mechanical relay prior to closing the electro-mechanical relay and to continue conducting electrical power around the electro-mechanical relay for a predetermined time after the onset of separation of contacts of the electro-mechanical relay pursuant to discontinuance of current flow through the electro-mechanical relay. An optical coupler is provided to ascertain a current flow through the relay coil effected to close the electro-mechanical relay contacts, and activates a shunt device in bridging electrical current flow around the electro-mechanical relay. The shunt device is provided to be substantially non-load carrying while the electro-mechanical relay is closed. Utility is found in protecting electro-mechanical relay contacts against damage due to arcing.

  • Patent number: 4745511
    Abstract: In a circuit having a electro-mechanical relay the contacts of which are subject to arcing, a shunt across the electro-mechanical relay configured to begin conducting electrical current across the electro-mechanical relay prior to closing the electro-mechanical relay contacts and to continue conducting electrical power across the electro-mechanical relay for a predetermined time after the onset of separation of electro-mechanical relay contacts pursuant to discontinuance of current flow through the elecro-mechanical relay. An optical coupler is employed to detect the current flow through the relay coil and activate a shunt device to initiate current flow around the electro-mechanical relay. The shunt device is configured to be substantially non-current load carrying while the electro-mechanical relay is closed. Utility is found in protecting relay contacts against damage due to arcing.
