  • Publication number: 20050020807
    Abstract: A method for producing trimethylene carbonate poly(trimethylene carbonate which comprises (a) introducing liquid poly(trimethylene carbonate) and an optional catalyst into a wiped film evaporator reactor under a vacuum about 15 kPa or less, said reactor having walls heated to at least about 230° C. and an internal condenser heated to a temperature above the boiling point of trimethylene carbonate, (b) spreading the poly(trimethylene carbonate) into a thin film and allowing it to flow down the interior surface of the heated walls, (c) depolymerizing the poly(trimethylene carbonate) to form trimethylene carbonate which is driven to the internal condenser and residue poly(trimethylene carbonate) which continues down the reactor, and (d) collecting the trimethylene carbonate in a cooled distillate receiver.

  • Publication number: 20040010630
    Abstract: A system and method for allowing a marketing entity or client to deliver marketing information on a product or service to a target group of consumers. The marketing entity can generate or modify parameters defining at least a part of a consumer interface and these can be associated with consumer data so that a user interface is associated with a target group of consumers. The target group of consumers can then be notified of the existence of the interface. This can be facilitated either by the automatic generation of the notification e.g. by e-mail, fax, or SMS message, or by the generation of contact information for the consumers to allow manual notification e.g. mail, telephone call or fax. The consumers are then able to access the interface and gain access to the information on a product or service. The consumer interface can comprise static information, which is dynamically generated on a request from a consumer and can comprise dynamic information, such as multimedia data.

  • Publication number: 20030224407
    Abstract: Methods are disclosed for assessing the toxic or pathologic effects of a selected environmental stimulus or reagent on a mammalian cell by determining on a DNA grid a “fingerprint” hybridization pattern. The fingerprint pattern is characteristic of chemically or structurally diverse stimuli or reagents, which having a common adverse effect on gene transcription. A test compound is screened for a similar toxic effect by comparing its hybridization pattern on a similar grid to the fingerprint.

  • Patent number: 6032033
    Abstract: A selection diversity system and method for use in a TDMA (time division multiple access) radio system, particularly suited for DECT (Digital Enhanced Cordless Telephone) or PWT (personal wireless telephony) applications. A digitized version of a received signal is buffered long enough to allow selection diversity measurements to occur without corrupting the demodulation of the desired signal. While the received signal is being buffered, a single receiver makes a performance measurement on each of two antennas in sequence during the beginning of a received data burst, the beginning of the burst being determined by a timing signal fed back from a previous burst. The previously unused antenna is measured first to minimize the likelihood of having to perform two antenna switches. Also while the received signal is buffered, timing recovery and frequency offset correction are performed.
