Abstract: An expandable metal product for use in extinguishing fires and in the prevention of or protection against explosions. The product is a continuous sheet of magnesium alloy foil having discontinuous slits in spaced apart lines parallel to each other but transverse to the longitudinal dimension of the sheet. The invention is also directed to the expanded form of the product, either in sheets which may be used for preventing fires or explosion or in the form of shaped ellipsoids for use in a passive inerting system for fuel tanks.

Abstract: A pivot arrangement for holding structural members, such as cattle stanchions, in pivotal engagement, with improved durability and wear resistance at the pivot point. In the stanchion (25) containing the pivot holes (36) and (37), an ultrahigh molecular weight, high density resin plastic insert (38) is positioned on the interior of the stanchion in the area surrounding the pivot holes (36) and (37). The resin insert has wear-resistant properties greater than the metal material from which the stanchion (25) is made. A pre-drilled bearing channel (42) in the plastic insert (38) is aligned to register concentrically with the pivot holes (36) and (36), and the plastic insert is secured in this position by dimples in the walls of the stanchion (25).

Abstract: A highly efficient anti-explosion pad comprising multiple sheets of expanded metal net separated by a core layer of porous material such as fiberglass, cotton batting or an assembly of miniature ellipsoids or balls formed from expanded metal net. When covering a wall or other structural element, the stratiform pad effectively dissipates the shock waves and thermal effects of a close range bomb explosion.

Abstract: A highly efficient fuel containment medium which is adapted to protect neighboring facilities against fire or explosion of flammable materials accidentally released from above-ground storage tanks. The fuel containment medium has special applicability for use in diked areas surrounding fuel storage tanks. The medium effectively suppresses flame heights and spread rates in pool fires in said diked areas. The containment medium comprises a mineral aggregate mixed with a flame-effects modifier such as fragments of expanded metal net made from magnesium alloy foil. In a preferred embodiment, the aggregate is sand or gravel, and the flame-effects modifier comprises ellipsoids formed from expanded metal sheets made from magnesium alloy foil.

Abstract: A stratiform pad for surrounding and protecting a bed sore from pressure while the patient is in bed. The pad comprises a median layer containing a closed cell air bubble film, a body-contacting layer bonded to one surface of the median layer to adhere the pad to the patient's body, and a bed-contacting layer bonded to the other surface of the median layer to adhere the pad to the bed surface. The pad contains an interior bed sore receiving aperture and provides sustained lift of the body away from the bed in the area of the sore, thus relieving the pain of pressure and providing space for the flow of healing air.

Abstract: A product useful in extinguishing fires and preventing explosions has a continuous sheet of metal foil having discontinuous slits arranged in a specified way, and in particular embodiments comprises magnesium alloys which may be coated with an oleate or an alkaline bichromate.

Abstract: A duplex plug for protecting conventional duplex electrical outlets, has dielectric caps connected by a flexible, generally S-shaped tether. Each cap has projecting prongs that fit the outlet receptacle, and the tether may have an aperture for deteachably securing it to a center mounting hole of the electrical outlet by means of a mounting screw. Use of the center mounting hole attachment is optional. The length and shape of the S-shaped tether are adapted to permit convenient biasing of a cap laterally away from one electrical receptacle.

Abstract: A method of producing an ellipsoid form from an expanded metal foil net teaches the steps of placing a sheet of expanded metal net on a work surface adjacent an open-ended hollow cylinder having the interior shape of a semi-ellipsoid, moving a first piston having the exterior shape of a semi-ellipsoid against the expanded metal sheet and into said open-ended cylinder to form the sheet into a semi-ellipsoid piece having a closed end and an open end, and subsequently moving a second piston into the open-ended cylinder to close the open end of the semi-ellipsoid piece and thus complete formation of the ellipsoid form. The metal foil may be a continuous sheet transversely slip and fed in unstretched form from a roll to the edge of said work surface, then stretched across the work surface and detached from the continuous sheet to provide the expanded metal net sheet to be formed into an ellipsoid.

Abstract: An electrolysis cell is provided for use in connection with a combustion engine, for generating hydrogen and oxygen gases which are added to the fuel delivery system as a supplement to the gasoline or other hydrocarbons burned therein. The hazard of explosion of the mixture of generated gases is eliminated by withdrawing the gases through a connection with the vacuum line of the positive crankcase ventilation (PCV) system of the engine and by utilizing a slip-fitted top cap for the electrolysis cell, which cooperates with the PCV vacuum line to prevent explosive containment of generated gases in case of accident. Use of the generated gases as a fuel supplement enables substantial increases in fuel efficiency, while at the same time reducing the emission of pollutants.

Abstract: This invention relates to methods and apparatus for cleansing oil-contaminated particulate materials. The invention is particularly applicable to the treatment of oil well drill sites and to methods and means for continuously cleansing drill cuttings found in used drilling muds. An initial step involves the use of an inclined tub equipped with an inclined spiral conveyor for continuous stripping of the oil and other contaminants from the drill cuttings, and a second step involves the use of a similar inclined tub and inclined spiral conveyor for continuous hot rinse water treatment of the stripped cuttings. An optional ambient or cold water final rinsing step is also disclosed.

Abstract: A high performance, laminating, coverlay, and bond ply adhesive material includes one or more epoxy components which inter-react with a high molecular weight polyester component through a two-stage reaction sequence. The first stage of the reaction sequence includes a reaction between a aziridine cure component and a polyester component. The second stage of the sequence involves a reaction between the aziridine/polyester component and the epoxy component(s). The resulting adhesive material provides a flexible, fully cross linked adhesive material with good Z-axis stability and without the evolution of volatile by-products. This resulting adhesive material can be used in bonding polyimide films to etched circuit patterns to provide a high temperature resistant, solvent resistant, moisture resistant, insulating material with good flow properties under normal electronic circuit processing and environmental conditions.

Abstract: A method for the production of fiber reinforced palstic composites, in which a continuously moving array of fibers is impregnated with resin and fast cured as it passes through a shadow boundary created by a source of radiant energy such as ultraviolet light. The method is useful for the production of axial composites such as tubes, pipes, conduits, ducts and the like, which may be created without mandrels by passing the array of fibers through closed dies. The method is also useful with open or rolling dies to create nonaxial composites such as wall panels, guard rails, vehicle body parts, and the like.
