  • Patent number: 5853631
    Abstract: A method for mold heater startup and sequencing detects the heater zones associated with greater mass and allows them to heat up before zones of lesser mass, thereby reducing wear of the associated mechanical components and minimizing degradation of plastic material. The zones of smaller mass are kept at minimal temperatures until the zones with greater mass reach a set point. The system is capable of detecting multiple levels of thermal load and provides appropriate sequential startup of the identified thermal loads. The operator may also manually program the system to override certain automated sequences in order to ensure an optimal startup sequence. The sequencing of power application to large heaters also minimizes the peak current draw of the system.

  • Patent number: 5853990
    Abstract: A method for performing real time, homogeneous assay of a target nucleic acid comprising annealing a labeled, ribo-oligonucleotide probe to the target DNA sequence and degrading a portion of the probe with RNase H to release labeled fragments.

  • Patent number: 5853653
    Abstract: Ceramic matrix composites (CMC) of high density, preferably of the type SiC/SiC, are provided by a production process based on the infiltration of ceramic fiber cloths with a polymeric precursor solution containing, as fillers, inert powders having size much lower than the mean distance among the ceramic fibers which are used as basic material for the manufacturing of CMC, typically a nanometric granulometry. Such step is followed by the steps of hardening the cloths, pyrolysis of the polymer and repeated thickenings until the desired density is reached. A possible alternative process comprises a brief (<24 hours) treatment of infiltration of SiC from the vapor phase (CVI) with precursors and typical operative parameters for the deposition of silicon carbide followed by the repeated thickenings.

  • Patent number: 5852218
    Abstract: A method for converting the diester of a polyether polyol (e.g., the diacetate ester of polytetramethylene ether, PTMEA) to a corresponding dihydroxy polyether polyol (e.g., polytetramethylene ether glycol, PTMEG) involving reactive distillation wherein a diester of polyether polyol is fed to the top portion of the column along with an effective amount of at least one alkali metal oxide or alkaline earth metal oxide, hydroxide or alkoxide catalyst (e.g., sodium methoxide) and with a C.sub.1 to C.sub.4 alkanol (e.g., methanol) while simultaneously adding to the bottom of the reactive distillation column hot alkanol vapor to sweep any alkanol ester formed by alkanolysis of the diester of polyether polyol upwardly. Such a process is useful for achieving high levels of conversion PTMEA to PTMEG on a commercial scale with the overhead from the column being amenable to azeotropic separation of the methyl acetate and recycle of the methanol.
