Abstract: A resin material for gas separation bases which has a cardo-type polymer structure in which at least 0.1 % of the hydrogen atoms of the pendant benzyl and/or allyl groups have been replaced by a halogen or a resin material for gas separation bases which comprises a polymer in which at least 34% of the hydrogen atoms of the pendant benzyl and/or allyl groups have been replaced by a halogen; the polymer constituting the resin material for gas separation bases which has the cardo-type polymer structure; and a process for producing the polymer. The resin material not only is excellent in solvent solubility, easiness of film formation by a wet process, thermal stability, chemical stability, etc., but has better performances with respect to gas permeability and gas selectivity. Thus, a gas separation base, especially a gas separation membrane, can be produced in which gas permeability and gas selectivity can be easily controlled.

Title: Dendrimer-photosensitizer complexes for medical applications
Inventor: RODER BEATE
IPC: A61K41/00
Filed: 2000-07-28
Abstract: A method for enhanced PhotoDynamic Therapy (PDT) treatments by applying dendrimer-photosensitizer complexes to bring multiple phototosensitizer moieties to a treatment site is provided. Photosensitizers are covalently coupled to the peripheral bonding places of dendrimers and are being separated in one or more successive cycles. Tetrapyrroles are the photosensitizers employed. In one embodiment the complex is also bound to an antibody or antibody fragment, which aids in targeting the complex to a desired treatment site. After application, the photosensitizers are released, at the treatment site, from the complexes by either light, chemical, or a combined light/chemical effect. Generally the photosensitizers develop their full photodynamic activity as free molecules after being released from the complex.  More than one type of photosensitizer may be bound in the complexes. Release and/or activation may be done in a single step or with repeated steps.

Filed: 2000-09-04
Abstract: Apparatus for determining the resonant frequency of a passive sensor, for example a saw device, comprises: means (5, 7, 3) for transmitting signals of  a plurality of frequencies to said passive sensor (2); means (3, 7) for receiving signals from said passive sensor simultaneously with said transmitting of signals; means (7) for comparing the received signals with t he transmitted signals to identify a characteristic change in the relationship between the received signals and the transmitted signals which occurs when t he sensor is being driven at its resonant frequency. Typically, as the frequenc y at which the passive sensor is driven passes through the resonant frequency of the sensor the phase and/or amplitude of the signal generated by the passive  sensor will change. By identifying this change of phase and/or amplitude the  point at which resonance occurs can be detected. The frequency of the transmitted signal at the moment when the comparison indicates that the sens or is being driven at its resonant frequency is the resonant frequency of the sensor.

Abstract: The present invention is a method of preparing a high molecular weight copolyester bottle resin that has excellent melt processing characteristics.  The method includes the steps of reacting a diacid or diester component and a diol component to form modified polyethylene terephthalate, wherein diol component is present in excess of stoichiometric proportions. Together, the diacid or diester component and the diol component must include at least 7 percent comonomer. The remainder of the diacid component is terephthalic acid or dimethyl terephthalate and the remainder of the diol component is ethylene glycol. The modified polyethylene terephthalate is copolymerized in the melt phase to an intrinsic viscosity of between about 0.25 dl/g and 0.40 dl/g to thereby form a copolyester prepolymer. Thereafter the copolyester prepolymer is polymerized in the solid phase to form a high molecular weight bottle resin that has an intrinsic viscosity of at least about 0.70 dl/g, and a solid phase density of less than 1.413 g/cc.
