  • Patent number: 5294498
    Abstract: An anode material composed mainly of a difficultly graphatizable carbon or coke (easily graphatizable coke) consisting essentially of carbon, phosphorus and oxygen, and containing phosphorus in an amount of 0.2 to 9.0 wt %, is disclosed. The anode material exhibits a peak in a .sup.31 P solid NMR spectrum in a range of .+-.100 ppm based on orthophosphoric acid, and a peak in a 2p orbital spectrum of a phosphorus atom in XPS of not more than 135 eV. The anode material is prepared by adding phosphoric acid or phosphorus oxides to an organic material or a carbonic material. A non-aqueous liquid electrolyte cell is produced from the above anode material, an Li-containing cathode and a liquid electrolyte.

  • Patent number: 4313832
    Abstract: Ion exchange fibers having a thickness of about 2-200 micrometers and a length more than twice the thickness are mixed as a slurry of cation, anion or mixed cation and anion exchange fibers, with or without powdered ion exchange resin of 2-250 micrometers diameter, to intertwine the fibers and immobilize any powdered resin present; the resins are coated from the slurry as a mat on to a filter support; liquids to be purified are passed through the mat until the ion exchange materials are exhausted; and the exhausted mat is stripped from the filter support by a backwash of liquid, gas or both.

  • Patent number: 4243132
    Abstract: In an apparatus in which cylindrical articles violently collide with one another as they roll down on the inclined skid rails, from the inlet to the outlet thereof, a control rail covered thick with a soft and elastic foamed substance is located. The control rail is positioned side by side in parallel to the skid rails, and frequently reciprocated vertically to brake the articles as they move downwards over the skid rails so that the maximum rolling speed is sufficiently reduced for restricting the noise of collision below an allowable level.

  • Patent number: 4147260
    Abstract: An apparatus which collects pipes, rods and similar objects parallel one another, to form a bundle. The apparatus includes at least one pair of transfer rails from which the pipes are transferred to a pair of roller chains where the pipes are collected. The roller chains are mounted on driving sprockets, swing sprockets, feed sprockets and take-up sprockets. The velocity of the take-up sprockets is lower than the velocity of the feed sprockets, causing the roller chain to sag therebetween, creating a space to collect the pipes.
