Abstract: A nonwoven textile panel for use as a fire retardant and sound deadening barrier in the interiors of aircraft, comprised of three layers of nonwoven textile fibers of polyphenylene sulfide fibers and Nomex brand aramid fibers that have been carded, cross-lapped, needle punched and thermally bonded by heating the panel to the temperature softening point of the polyphenylene sulfide fibers. The fibers are capable of being thermoformed and retaining a permanent shape due to the thermoplastic properties of the polyphenylene sulfide fibers.

Abstract: Latex coated electrodes comprising a foraminous, electrically conductive substrate which supports a paste comprising a mixture of (a) finely divided, particulate, rechargeable, active material and, (b) a fibrous interconnecting network of an unsintered, uncoalesced, hydrophobic linear fluorocarbon polymer, wherein said active material is dispersed throughout and bound in said fibrous network and being accessible to said electrolyte and to gas being generated during overcharge of the cell have excellent mechanical integrity. These electrodes have a greater storage life than similar uncoated electrodes and rechargeable cells employing these electrodes have excellent electrical properties with respect to both voltage characteristics and pressure buildup.

Abstract: A cargo bed liner system for use in pickup trucks, four-wheel drive vehicles, light utility vehicles and the like, in which rigidified carpeting material made of needle-loomed staple fibers of polypropylene and polyester have been thermoformed to form a floor covering piece, a tail gate covering piece, and two side covering pieces, with flaps on the floor piece being folded upwards to cover the forward panel and any areas of the side panels which have not been covered by the side panel cover pieces. The system is affixed to the vehicle's cargo bed by means of several velcro-type fasteners.

Abstract: An airspring sleeve and airspring that each have a chamber portion and rolling lobe portion reinforced with successive layers of embedded cord where cord in one layer is wound at opposite helical angles from cord of a second successive layer and where the cord is wound at inconstant helical angles in an annular band portion of least one of the sleeve portions.

Abstract: A surface of an elastomer mass subject to stress by a force supplying member is protected from abrasion and cracking by interposing a silicone rubber layer between the elastomer mass and force supplying member.

Abstract: An elastomeric belt and hose conductivity testing device incorporating a comparator network to verify that a belt or hose is either conductive or nonconductive (resistive) of the flow of static electricity. The device indicates whether the article being tested has a resistivity or conductivity which meets the industry standard of resistivity or conductivity for that particular article. The testing device is battery powered so that it is easily portable for use in the field.

Abstract: A nonwoven textile panel for use as a fire retardant and sound deadening barrier in the interiors of aircraft, comprised of five layers of nonwoven textile fibers of polyphenylene sulfide fibers and Nomex brand aramid fibers that have been carded, cross-lapped, needle punched and thermally bonded by heating the panel to the temperature softening point of the polyphenylene sulfide fibers, whose panel exterior is comprised of a skin of polyvinyl chloride that has been adhered to the outermost fibrous layer. The fibers are capable of being thermoformed and retaining a permanent shape due to the thermoplastic properties of the polyphenylene sulfide fibers. An important alternative embodiment uses a layer of polyester polyurethane foam underneath the vinyl to shield it from the heat radiating properties of the polyphenylene sulfide and prevent puckering of the vinyl material during the processing.

Abstract: A collapsible generally cylindrical storage vessel having a flattened ramp end portion which accommodates driving upon by a vehicle or the like to pressurize the vessel and dispense fluid, as required. The ramp end is internally reinforced with a bridging insert which inhibits blowout upon pressurization.

Abstract: An annularly shaped elastomeric core type joint packing having a fiber reinforcement, having a radial reinforcing effect with respect to a longitudinal axis of the core.

Abstract: A reformable, shape retentive hose having a precured tube located in a hose sidewall, and a reformable rod inserted in the precured tube. A method for making hose by placing at least one precured tube in the sidewall of a hose during the time that the hose sidewall is formed, curing the hose assembly with the precured tube in the sidewall, and inserting a reformable rod in a portion of the precured tube.

Abstract: A circuit for supplying energy from a battery to the load of an energy-using device is provided wherein the circuit provides for notification to the operator of the device that the remaining energy of the battery is low. The notification is provided at a time when sufficient energy remains in the battery for the operator to perform certain essential tasks. The circuit includes a battery having a plurality of cells connected in series, a first portion of which have a higher deliverable energy capacity than a second portion of the plurality of cells. The circuit further provides for sensing a characteristic of the battery indication of the remaining deliverable energy capacity lower deliverable capacity cell portion and for switching the circuit from a first mode of operation wherein energy is delivered to the load from all of the cells in the plurality to a second mode of operation wherein the energy is delivered to the load from only the higher capacity portion of cells.

Abstract: A rack system for the display or storage of articles, which uses a hanger fabricated of a heavy gauge steel wire, so as to form a Z-shaped hanger having an article carrying portion in the middle, a retaining hook leg on one end, and a seating leg on the other end, which is seated within a trough that is attached to the front of a rack plate. The hanger is capable of sliding longitudinally back and forth along the front of the rack plate, but is prevented from upward escape by a channel, which has been affixed to the front of the rack plate, which channel holds identification tags, which are also able to freely slide back and forth along the front of the rack whenever the hangers are moved back and forth along the front of the rack. Also, there is described a method of rearranging articles by longitudinally sliding a hanger and its attendant identification tag whenever an inventory change occurs.

Abstract: A method and apparatus are provided for manufacturing an electrode for a rechargeable electrochemical cell by electrodepositing a metallic active material on a continuously moving metallic strip emmersed in an electrolytic bath containing an anode of the metal to be deposited. After depositing the metallic active material on the strip, the strip is passed through a second electrolytic bath wherein the metallic active material is at least partially oxidized.
