  • Patent number: 6145879
    Abstract: A fabric cover (9, FIG. 2a), which is shrinkable at least in part, for encapsulating at least part of an expandable object such as an automotive airbag (1), the fabric cover being provided with a predetermined region of weakness (13), preferably a catch thread holding the edges of a woven fabric together to form a tubular or flat cover, which region of weakness will rupture when the said object expands by greater than a predetermined amount, e.g. in an automobile accident. The region of weakness (13) and preferably fabric regions (11) immediately adjacent thereto may be of a contrasting color to facilitate alignment of the region of weakness in the direction of expansion of the expandable object.
    Type: Grant

  • Patent number: 5786443
    Abstract: A continuous process for preparing polyester prepolymer comprising the steps of esterifying a diacid with a diol, reacting the esterified product with additional diol, and passing the product downward through a countercurrent column reactor while inert gas flows upward through the column reactor. The resulting prepolymer product has fewer acid end groups than the esterified material.

    Inventor: David James Lowe
  • Patent number: 5645906
    Abstract: A cable splice case or other article for environmental sealing comprises a composite material having multifilament fibres therein, which fibres are blocked in order to prevent passage of fluid through the material in a direction parallel to its major surfaces.
    Type: Grant
    Filed: July 15, 1994
    Date of Patent: July 8, 1997
    Assignee: Raychem Limited

  • Patent number: 4081333
    Abstract: Phosphorus is recovered from phosphorus mud by introducing a skip of phosphorus mud into a furnace, closing the furnace and contacting the skip inside the furnace with a pool of molten lead. Phosphorus vapour is distilled from the mud and recovered.

    Inventors: William Samuel Holmes, Edward James Lowe, Ernest Reginald Brazier
  • Patent number: 4024320
    Abstract: A current collecting pole associated with an alkali metal-sulphur cell comprises a first layer of an electronically conducting material which is resistant to the corrosive action of sulphur and alkali metal polysulphides (e.g. carbon or graphite) and which defines a continuous surface in contact with the sulphur and alkali metal polysulphides and a second layer of a higher electronically conducting material which is in electrical contact with the first layer over the surface of the latter remote from the sulphur and alkali metal polysulphides.

  • Patent number: 4014806
    Abstract: Novel organic polyphosphate mixtures are made by a process comprising a mixture of a plurality of polyphosphate salts of one or more primary, secondary or tertiary amines; which mixture has been obtained by a process comprising (1) forming an aqueous polyphosphoric acid solution comprising from 80 to 88% by weight of phosphorus penitoxide; (2) reacting said polyphosphoric acid solution with a primary, secondary or tertiary amine at a pH of from 4 to 12 and at a temperature of from 15 to 70.degree. C.Such mixtures are useful as builders in liquid cleaning compositions comprising surface active agents or alkali metal hydroxides or silicates with which they are more compatible in aqueous solution then are previously used polyphosphate builder materials.

  • Patent number: 4013756
    Abstract: There is provided a method for preparing phosphorus compounds wherein phosphorus vapor containing P.sub.2 molecules is condensed at a temperature below the solidification point of red phosphorus and the resulting solid is then reacted with a phosphorus-reactive material. When the phosphorus-reactive material is water at an elevated temperature, phosphine is produced.
