Abstract: An externally propelled load transporting apparatus that transports a uniformly distributed, non-uniformly distributed, or shifting load upon a cushion of air by first directing pressurized air into at least two plenum chambers and then through at least one flexible perforated sheet, wherein each plenum is substantially, independently pressurized.

Abstract: A toothed power transmission belt having a high modulus polyurethane body, an aramid type -II tensile member occupying up to about 88 percent of the belt width, and a wear-resistant fabric disposed along the belt inner surface at the tooth flanks.

Abstract: A vehicle sensing device comprises an electrically insulating elongate carrier (1) with two electrical conductors (2,3) extending longitudinally of the carrier and spaced apart transversely of the carrier so that there is no direct contact between the conductors. A strip (14) of elastomeric material overlies both conductors and is in contact therewith in areas distributed along substantially the whole of their length. The strip (4) being such that in the absence of a given level of applied pressure the strip forms a barrier of high electrical resistance between the conductors, and that in the presence of applied pressure above the given level in any region of the strip, that region of the strip forms an electrically conductive path between the conductors. The carrier, conductors and strip are wholly encapsulated in a jacket of water-resistance and abrasion-resistance elastomeric material.

Abstract: A ground effects device of the type that introduces pressurized air into a plenum chamber, that then travels through a perforated flexible sheet to form an air cushion, the improvement therein that no air dispersion means are present in the plenum chamber.

Abstract: A quick connect female coupling with a brasing means in a bore of the coupling that bias an O-ring type packing in sealing engagement against part of the coupling and a pipe end portion when the coupling is in use. A retaining ring in the coupling snap fits against an external collar of a pipe end portion as a retaining means when the coupling is in use.

Abstract: A power transmission belt with discontinuous fiber protruding and bent from oppositely facing friction driving surfaces to expose lateral side portions of fiber.

Abstract: A T-shaped connector for use in automotive radiator cooling systems, in which each nipple is radially enlarged to form a substantially frusto-conical obverse taper, an apex, and a substantially frusto-conical reverse taper having one or more shouldered steps cut into it. The height of the apex is determined as a function of the elastic properties of the rubber hose to be connected to the coupling, a rubber hose is slid onto and over the radially enlarged portion, and a substantially frusto-conical ring is seated onto that portion of the hose fitting over the reverse taper of the nipple.

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 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 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 safety hose having a stretchable elastomeric tube and cover that sandwich a twined reinforcement that exhibits a circumferential reinforcement component and a weaker longitudinal reinforcement component that breaks when the hose is stretched.

Abstract: A hose article for carrying volatile fluids, which can conduct and dissipate the accumulation of static electrical charges that are associated with such volatiles, which includes an elastomeric tube and outer sleeve and at least one reinforcement layer of fiber bundles sandwiched between the tube and the cover. Sandwiched between the tube and the reinforcement layer is a nontwisted yarn of fibers of carbon that runs in a direction generally lengthwise to the axis of the tube, and at the end of the tube makes electrical contact with a staple-shaped metallic connector, which in turn electrically contacts a metallic hose coupling, leading from there to an electrical ground.

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 reinforced hose and coupling assembly is disclosed that will withstand very high pressures without bursting. A modified seal ring eliminates shear planes in the wire reinforcement near the fitting end of the coupling and thereby reduces the possibility of failure of the hose coupling at high pressure. The assembly also incorporates the use of a fluoroelastomeric tube liner and fluoroelastomeric seals to prevent the permeation of H.sub.2 S gas into the anchoring matrix.

Abstract: A coupled hose assembly of the type including a coupling attached to a polymeric hose by pinching part of a hose end portion. A pliable adhesive is disposed in part of the coupling to define a substantially leakproof seal between the hose and coupling at an environment temperature falling at least within the range of about 135.degree. C. to about -40.degree. C.

Abstract: A toothed belt that has a tensile member of spirally wound cord where the operating pitch line of the belt is at least partially established by the cord which is made by twisting together at least two substantially zero twist, unequal denier yarn ends to form a ply, and twisting at least two of such piles together in the opposite direction to form the cord.
