Abstract: The application relates to quinhydrone (RN=106-34-3) containing sensors (10) for e.g. potentiometric measurements, especially in vivo measurements such as potentiometric pH measurements in wounds. In particular, the application describes methods for preparing crystalline quinhydrone for use as an ink in the manufacture of such sensors. By combining concentrated aqueous solutions of benzoquinone and hydroquinone in the presence of a water soluble polysaccharide derivative, especially hydroxypropyl methyl cellulose (HPMC), crystals of quinhydrone are obtained which are characterised by a low aspect ratio (<2.5). This renders them especially advantageous for use in pH electrodes.

Abstract: The present invention provides a novel one-piece capstan for a tape cartridge which provides good static dissipative properties and wear resistance. The capstan material of the present invention has a charge decay time of no more than 5 seconds as measured according to Mil B-81705C standard. The capstan material also has a flexural modulus of at least 200,000 psi (1379 MPa). The capstan comprises a hard, dimensionally stable polymer and a static dissipating polymer. The capstan also has an improved structure and geometry which enables the part to be easily molded, reduces drive force requirements with a reduction of material from the prior art design, but with no significant loss of performance properties.
