Inventor: DAVALL PETER W N
IPC: F23N5/08
Filed: 1990-04-20
Abstract: METHOD AND APPARATUS FOR DETECTING FLAME                 ABSTRACT OF THE DISCLOSURE           A method of detecting flame within a region where flame is expected.  Radiation emissions from the region are measured within selected portions of the visible and infra-red frequency bands.    Spectral  characteristics  of  the  two measurements, including their auto spectra, coherency and transfer function, are derived.  The derived spectral characteristics are compared with prestored spectral signatures representative of the spectral characteristics of radiation emitted from the region within the selected portions of the visible and infra-red frequency bands while known flame conditions prevail within the region - thereby estimating the deviation of the derived spectral characteristics from the prestored spectral signatures. The deviations aforesaid are compared with predetermined threshold alarm values to assess the presence or absence of flame.

Abstract: A process  for manufacturing high-purity o-toluic acid from a partial oxidation product of o-xylene is disclosed.  o-Toluic acid is widely used as a raw material for agricultural chemicals, medicines, polymerization initiators, and the like. Depending on its use, 99% by weight or more purity is demanded for o-toluic acid.  Hitherto, o-toluic acid having purity of higher  than  99%  by  weight  could  not  be  obtained  by fractionation, and purification by fractional crystallization was  used.    Fractional  crystallization  is,  however, an expensive operation and not only gives a low yield of product but also results a large amount of waste water.  The process disclosed herein gives an economical, commercial way to obtain high purity o-toluic acid.   In summary,  a process for the manufacture  of high purity o-toluic  acid which comprises: subjecting an oxidation product of o-xylene to distillation to remove  therefrom  low  boiling  point  components  such  as unreacted o-xylene and benzoic acid,  and high boiling point components, of which the major component is o-methylbenzyl o-toluate,  thus obtaining crude o-toluic acid,  treating said crude o-toluic acid with ammonia of an amount 1 to 1.2 mol equivalent of o-phthalic acid contained in said crude o-toluic acid, and subjecting the product thus treated to distillation is disclosed.

Abstract: Apparatus and method for increasing efficiency of command execution  from  a  host  processor  over  an  SCSI  bus. Arbitration, selection and message out functions of SCSI protocol are implemented using a background arbitration state   machine.    Additional   protocol   functions   are implemented in a foreground state machine.  When the host processor issues a command for access to the SCSI bus, the background  state machine  can be programmed before  the foreground machine completes the protocol function for a previous command.  Thus, the background state machine is ready to arbitrate for access to the bus at the very next bus free condition.
