Title: Bacillus thuringiensis isolates active against dipteran pests
Inventor: PAYNE JEWEL M
IPC: A01N63/23
Filed: 1991-09-17
Granted: 2003-12-02
Abstract: Disclosed and claimed are novel Bacillus thuringiensis isolates designated B.t. PS192N1, B.t. PS92J, B.t. PS196S1, B.t. PS201L1, and B.t. PS201T6, which have dipteran activity. Thus, these isolates, or mutants thereof, can be used to control such insect pests. Further, genes encoding novel .delta.-endotoxins can be removed from these isolates and transferred to other host microbes, or plants. Expression of the .delta.-endotoxins in such hosts results in the control of susceptible insect pests in the environment of such hosts.

Title: Gas-solid contacting method
Inventor: GOODES CHRISTOPHER GEOFFREY
IPC: B01D53/10
Filed: 1991-08-02
Granted: 2002-04-30
Abstract: A gas scrubbing process is disclosed whereby particulate material is contacted with a high velocity exhaust gas stream to reduce the resistance to mass transfer attributable to the diffusion boundary layer and provide higher mass transfer rates. The process is particularly suited to the scrubbing of gaseous fluorides from aluminium smelter pot exhaust gas with alumina. Addi-tionally, it has been found that the fines fraction with a particle size of preferably less than 45 µm adsorbs or chemisorbs a dispro-portionate amount of contaminant trace metals from the exhaust gas stream. To avoid recycling these trace metals contained in the exhaust gas back to the smelter pot the fines fraction may be elutriated from the coarse fraction.

Granted: 1999-08-17
Abstract: Data receiving apparatus receives a spread spectrum signal prepared by modulating data with a carrier wave to produce a data modulated signal, and multiplying the data modulated signal with a spreading signal that has a bandwidth greater than that of the data modulated signal. The receiving apparatus has three bandpass filters for passing three different band portions of a full band of the spread spectrum signal, and respectively producing a bandpass signal, a detector for detecting an intermediate signal from the bandpass signal and for producing a detection signal, and a reception state evaluation device for detecting the current reception state of the detector and for producing a poor reception signal when said detector is in a poor reception state. The poor reception signal is used for changing the current band to another band. The apparatus has the advantage of not requiring a wide band delay, and can tolerate strong interference components superimposed on the spread spectrum signal.
