Abstract: There is disclosed an upholstered article of furniture in the form of a pouffe (10) which comprises a base (11), a single scrap rubber tire, or a stack of rubber tires, mounted generally horizontally on the base, upholstery (13), and padding (14) arranged at predetermined locations between the tire and the upholstery.

Abstract: Toroidal field coils are interlaced with other toroidal structures and are operated under supercooled conditions. To facilitate demounting the toroidal field coils, which are supercooled, they are made in the form of connected segments constituting coils of polygonal form. The segments may be rectilinear in form, but some may also be U-shaped or L-shaped. The segments are detachable from one another and are supported in load relieving manner. Power devices are used to displace the segments to facilitate removal of the coils from the aforesaid toroidal structures and to provide for the accommodation of dimensional changes and stresses due to thermal and magnetic conditions. The segments are formed of spaced parallel conductive slabs with the slabs of one segment being interdigitated with the slabs of the adjacent segment. The interdigitated slabs may be soldered together or slidingly engaged. The slabs are shaped to accommodate superconductors and to provide passages for a cooling medium.

Abstract: A coupling nut is rotatably mounted on a barrel and retained thereon by the means of a snap ring. The snap ring is formed with forwardly and rearwardly extending tabs at its free ends which cooperate with a slot formed in the outer surface of the barrel and a recess formed in the inner surface of the nut which allows the nut to be assembled onto the barrel and removed therefrom without the use of a tool.

Abstract: Process for ionically crosslinking first copolymers formed by copolymerizing at least one alpha-olefin of the general formula RCH=CH.sub.2 where R is hydrogen or hydrocarbyl having 1 to 8 carbon atoms and at least one alpha, beta-ethylenically unsaturated carboxylic acid having 1 to 2 carboxylic acid groups and 3 to 8 carbon atoms, the alpha-olefin content of the first copolymer comprising at least 50 mole percent of the first copolymer, the alpha, beta-ethylenically unsaturated acid content of said first copolymer comprising 0.2 to 25 mole percent of the first copolymer which comprises mixing the first copolymer with a cation-supplying blend of 20 to 80 percent by weight of substantially water-insoluble zinc oxide and/or zinc hydroxide and/or zinc carbonate, 0 to 10 percent by weight of a lubricant and a complemental amount of a second copolymer with a melt index of 50 to 2000 g./10 min. formed as the first copolymer, at a pressure of 100 to 10,000 p.s.i.

Abstract: The disclosure of this invention pertains to a gas turbine engine having an annular combustion chamber having an outlet duct to turbine entry vanes, an extension of the combustion chamber connecting a radially outer wall of the duct to fixed structure at a position adjacent the downstream and of the vanes, wherein the wall is covergent in the downstream direction, the extension is connected to the wall at a location upstream of the downstream extremity thereof, and cooling air passages ae arranged to lead cooling air to the junction so that on heating of chamber in operation said extremity expands radially outwardly and in the downstream direction thereby to make sealing engagement with an adjacent extremity of a shroud ring of the vanes.
