  • Patent number: 6122889
    Abstract: The present invention describes a lightweight, flexible, weather resilient, seamless, waterproof, and thermoplastic roof covering layer and a method to prepare such a layer. The method is similar to that used in the preparation of clothing wherein a pattern, which may be out of paper, is prepared according to the measurements of the roof and any protruding or embedded structures thereon. Thermoplastic fabric is cut according to the pattern specifics. The fabric pieces are attached to each other to form a snugly fitting roof covering layer which is then fused and compressed in situ.

  • Patent number: 5937603
    Abstract: Improvements in a roof covering system include the use of flexible pouches containing heavy, dense materials such as dense oil and sand. These pouches are compressed between supports, such as parapet walls and pipes, and fixtures mounted on the supports, resulting in improved sealing against water seapage into the roof.Another improvement is in the provision of a storage tank of sealing material such as tar to help maintain the level required for adequate protection of roofing materials against adverse weather conditions. The additional provision of a wetted layer between two water impermeable layers allows for better temperature control of the roofing materials. Temperature controlled water can be circulated through this wetted layer using a system of spiralling pipes with an underground water storage area of larger spiral piping.

  • Patent number: 5733408
    Abstract: A novel heater roller system capable of reaching temperatures in excess of 400 degrees Centigrade is used in situ to prepare highly weather resistant polymeric covering materials by compressing and fusing a layer of fibers and fiber particles by heating the layer through an overlayer of an air-impermeable, heat tolerant material such as aluminum. The fiber layer may contain reinforcing fibers, heat conductive metal flakes, and/or other additives. Such a layer is particularly useful as a roof covering material made in situ.

  • Patent number: 5658178
    Abstract: Frames for flotation devices are described with integrally incorporated attachment sites for the air tight attachment of recycled plastic bottles, aluminum beverage cans, or other bouyant containers. Several embodiments of flotation devices made with such frames are described including floating mattresses, a raft, a baby seat, a bouy, a pool pillow, and a bumper. The devices discussed are easy to transport and to stow. Further, they are inexpensive and provide an incentive to recycle used bouyant bottles and cans for making the flotation devices of this invention.

  • Patent number: 5434758
    Abstract: A novel compact and portable lighting system can be used for both mobile and immobile vehicles. The lighting system can act both as auxiliary lighting and as back-up lighting for standard vehicle light systems. This novel system includes an auxiliary portable power source such as a battery and a control box which can be mounted on the inside of a window. The lighting assemblies connected through the control box can include any combination of headlights, brake lights, reverse lights, signal lights, hazard lights or other useful lights. The lighting assemblies connected to the control box can be enabled independently of each other. The frame upon which the lights are mounted is adjustable in size so as to be able to fit any sized vehicle. A preferred means to secure this novel portable lighting system is with magnetic suction cups so that the invention can be secured to both metallic and nonmetallic surfaces. This enables rapid placement and easy removal of the lighting system as desired.

  • Patent number: 5365703
    Abstract: A water, fire and heat proof roof is provided and consists of a tar holder affixed about an inner surface of a parapet, so that a lower portion of the tar holder will overlap and cover curved ends of an upper layer of polymer roof covering material to help keep the roof water proof, heat proof, fire proof and cool. A water sprinkler system is also utilized to prevent a fire and reduce heat on the roof to keep it cool.
