Patent CA-2111497-A1 (CA)
Inventor: GARG DIWAKAR
IPC: B01D53/46
Filed: 1993-12-15
Abstract: An integrated two-step process for producing low-cost atmospheres suitable for annealing ferrous and non-ferrous metals and alloys, brazing metals, sealing glass to metals, and sintering metal and ceramic powders in continuous furnaces from non-cryogenically produced nitrogen containing up to 3% residual oxygen is disclosed. The residual oxygen present in non-cryogenically produced nitrogen is converted to moisture by mixing it hydrogen and passing the mixture through a reactor packed with a platinum group catalyst in the first step of the process. The reactor effluent stream containing a mixture of nitrogen, unreacted hydrogen, and moisture is mixed with a pre-determined amount of a hydrocarbon gas and introduced into the heating zone of a continuous furnace in the second step of the process to 1) convert moisture to a mixture of carbon monoxide and hydrogen by reaction with the hydrocarbon gas via water gas shift reaction and 2) produce atmospheres in-situ suitable for heat treating. The key features of the process include 1) use of economical amount of hydrogen to convert residual oxygen to moisture in an external catalytic reactor and 2) conversion of moisture to a mixture of carbon monoxide and hydrogen by reaction with the hydrocarbon gas via water gas shift reaction in the hot zone of a continuous furnace. The disclosed process is particularly suitable for producing low-cost heat treating atmospheres for continuous furnaces operated at 700°C and above.
Patent CA-2112130-A1 (CA)
Inventor: EDWARDS CYNTHIA A
IPC: C12Q1/68
Filed: 1992-06-26
Abstract: The present invention defines an assay use-ful for screening libraries of synthetic or biological compounds for their ability to bind specific DNA test sequences. The assay is also useful for deter-mining the sequence specificity and relative DNA-binding affinity of DNA-binding molecules for any particular DNA sequence. The assay is a competition assay in which binding of a test mole-cule to a DNA test sequence changes the binding characteristics of a DNA-binding protein to its binding sequence. When such a test molecule binds the test sequence the equilibrium of the DNA:protein complexes is disturbed, generating changes in the ratio between unbound DNA and DNA:protein complexes. The assay is versatile in that any test sequence can be tested by placing the test sequence adjacent to a defined protein binding DNA screening sequence.

Title: Frequency synthesizer
Inventor: URIYA SUSUMU
IPC: G06F7/72
Filed: 1994-02-14
Abstract: ABSTRACT OF THE DISCLOSURE        A saw-tooth waveform signal generating circuit 3 generates a saw-tooth waveform signal d in response to a timing signal b derived from a reference clock a.  A voltage comparator 4 slices the saw-tooth waveform signal with a reference voltage to shape the waveform thereof, thereby producing a synthesizer output e having a rectangular waveform.  A counter 5 adds or subtracts a predetermined value every time a reference clock arrives.  The count of the counter 5 is converted to an analog value by a DAC 6 and then is applied to, for example, the saw-tooth waveform signal generating circuit as a bias.  As a result, the voltage for causing the saw-tooth waveform signal to start rising or falling is manipulated to allow the voltage comparator to slice the saw-tooth waveform signal at any desired timing.  Hence, a synthesizer output can be produced in any desired phase.
