Abstract: An apparatus is described for the coating of a human body with a tanning composition, such as a sunless tanning composition, wherein an arm with a plurality of nozzles thereon traverses within a booth to spray coat a body in the booth. The spray nozzles are oriented to avoid opposing air flows and excessive air flows which cause inefficient and uneven, dripping or streaking in the deposition of tanning composition on the skin. In another aspect, the apparatus provides for a foot rinser to rinse the feet of a user while the apparatus applies a sunless tanning composition to the user to avoid overly darkening the user's feet. In yet another aspect, the apparatus provides for a sanitation system to wash-down the spray booth between successive uses.

Abstract: There is disclosed the use, as an agent in the treatment or the prevention of an autoimmune disease, of: (i) an agent having GM-1 binding activity, other than Ctx or Etx, or the B subunits of Ctx and Etx; or (ii) an agent having an effect on GM-1 mediated intracellular signalling events, but no GM-1 binding activity. These agents may also be used in the treatment of human T cell leukaemia, in the prevention of transplant rejection or GVHD or in a vaccination method for vaccinating a mammalian subject.

Abstract: A method is provided for reducing the amount of hydrogen sulfide and organic sulfides present in streams, such as natural gas streams, by scrubbing the stream with a composition containing (i) an aqueous phase containing a reaction product resulting from the reaction between an aldehyde, such as formaldehyde, and a first amine, such as monoethanolamine or aminoethylpiperazine, and (ii) an organic phase containing at least a second amine, such as butylamine, pentylamine or hexylamine, to produce: (1) a stream having a diminished amount of sulfide contaminants and (2) a sulfided reaction product, such as trithiane. The sulfided reaction product is solubilized into the organic phase (which precludes the formation of solids), and this resulting sulfided reaction product-containing organic phase is separated from the aqueous phase. The sulfided reaction product-containing organic phase may be used as a corrosion inhibitor, and the composition has reduced foaming characteristics during the scrubbing step.

Abstract: A rotary shaft assembly including a mechanism by which one part of the shaft rotates about a rotation axis which is controllably deviated from the rotation axis of the other part of the shaft. The angular extent of deviation is controllably varied by mutually rotating adjacent shaft supports about an axis which is at a non-zero angle with respect to both rotation axes. The direction in which the shaft is deviated is controlled by rotating the non-deviated shaft support with respect to a reference shaft support. The assembly includes remote control of direction and deviation and is is particularly applicable to drilling of deviated wells. Further, the assembly includes a remotely actuated and de-actuated temporary anchoring system for downhole direction sensing and deviation adjustment.

Abstract: Nitrilase enzymes are provided which have Km at pH 7.0 for acrylonitrile of 500 .mu.M or below. The enzymes also have Ki at pH 7.0 for ammonium acrylate of at least 100 mM. In particular, the nitrilases have a value of the ratio of the said Ki to the said Km of at least 200. Particularly preferred nitrilases are obtainable from the microorganisms Rhodococcus rhodochrous NCIMB 40757 or NCIMB 40833. These nitrilases can be used in processes of converting acrylonitrile to ammonium acrylate in aqueous or vapor form and for detecting low levels of nitrile in aqueous or vapor form.

Abstract: The invention provides a range of modified organoclays comprising intercalated moieties to provide an effective mechanism for attracting organic compounds into the interlamellar spaces in close proximity to other intercalated reactants. The intercalated moieties provide three functions, namely (a) pillaring to create adequate interlamellar spacing to provide access for larger molecules, e.g. polychlorinated biphenyls and poly aromatic hydrocarbons, (b) organophilic attraction of like polarity organic compounds, and (c) a reactive environment in which the organic substrates can be permanently bonded to the clay surfaces and pillaring agents. The invention also resides in methods of treating soil or other materials with such modified organoclays in order to remove or bind hazardous organic molecules.
