Patent CA-2070853-C (CA)
Title: Method and apparatus for minimizing environmental release of toxic compounds in the incineration of wastes
Inventor: LERNER BERNARD J
IPC: B01D53/70
Filed: 1992-06-09
Granted: 1998-10-20
Abstract: A method and apparatus for minimizing the environmental release of acids and toxic organic compounds from a waste incinerator-air pollution control train.  The apparatus comprises an incinerator, a gas cooling means such as a waste heat boiler or quench chamber, a means for the partial removal of acid gases and dioxins by contact with either finely-divided alkaline solids or alternatively, by an alkaline solution in a spray drier-absorber, a dry solids collection means such as a fabric filter or electrostatic precipitator, a wet scrubber means for residual metal, dioxin/acid gas removal and an induced draft fan. In the method, of this invention, the final wet scrubber stage operates without alkaline neutralization, but under scrubber acid concentrations and operating conditions that provide an exhaust gas within compliance limits of emission regulations.  The contaminated liquor blowdown from the wet scrubber, which contains toxic organics and acids is recycled back into the incinerator.  The aqueous acid liquor blown down to the incineration is vaporized therein, most of the toxic organic content of the liquid is destroyed by the re-incineration, and the regenerated acid gases are largely removed by the first dry scrubbing stage.

Granted: 2005-02-08
Abstract: The invention pertains to a novel method and plasmid system for producing abundant quantities of CRM197 protein, diphtheria toxin or other CRM proteins related to diphtheria toxin, as well as to microorganisms transformed with the novel plasmid. A particularly preferred DNA plasmid, designated pPX 3511, that combines the gene for CRM197 from the nontoxigenic betaphage and the plasmid pNG2-22 is described. The novel plasmid system is capable of transforming strains of Corynebacterium diphtheriae into strains which are capable of expressing high levels of the CRM197 protein without the use of multiple lysogens. The invention provides an elegant means for increasing protein production without having to manipulate the expression vector, such as by increasing the promoter strength, or removing the promoter from iron regulation.

Abstract: An apparatus for generating the interrupt information includes an addressing device for generating the specified address information for specifying the desired information stored in a memory device, a readout address generating device for generating the readout address information of the desired information stored in the memory device, and a comparator device for comparing the specified address information from the addressing device and the readout address information from the readout address generating device and for generating the interrupt information in case of coincidence of the specified address information and the readout address information and supplying the interrupt information to a central processing unit.      Since the interrupt data is supplied to the central processing unit at the playback timing of the desired sound source data, reproduction of the sound source data can be detected, so that it is unnecessary for the central processing unit to poll the address of the sound source data at all time and hence the load imposed on the central processing unit may be correspondingly decreased.

Title: Treatment of contaminated water in clays etc.
Inventor: CHERRY JOHN ANTHONY
IPC: E21B43/26
Filed: 1995-05-19
Granted: 2003-05-13
Abstract: The treatment system involves the use of hydrofracturing in drilled boreholes over the treatment area.  The hydrofracturing fluid contains treatment material, of the kind that causes chemical breakdown of the contaminant.  The breakdown leads to a contaminant concentration of zero in the hydrofracks, and therefore the contaminant diffuses towards the hydrofracks, where it is in turn broken down. Calculations and measurements indicate whether natural cracks in the ground are far enough apart to make hydrofracturing worthwhile.  A formula indicates, from an assessment of diffusion coefficients, etc, whether the contaminant will be rendered safe within a given time period.

Granted: 2001-08-14
Abstract: A novel process for recovering glycols  from used glycol-containing technical fluids is disclosed.   Used glycol-containing technical  fluids has  added to  it an organic  solvent  which  forms  with  the  glycols  to  be separated off,  an azeotropic mixture which has a lower boiling point than the glycol itself.   This azeotropic mixture is then distilled off.   A typical used glycol-containing technical fluid as used is antifreeze.   The preferred organic solvent is a xylene or a pseudocumene.          Prior to the addition of solvent which forms the azeotropic mixture with the glycol,  a water portion in the used glycol-containing technical fluid, if present, can also be advantageously first removed by distillation.

Inventor: ROSENBAUM STANLEY DANIEL
IPC: H04M19/02
Filed: 1993-06-30
Granted: 1998-04-21
Abstract: A two-wire telephone line is supplied with d.c. feed from a drive circuit (10) including two amplifiers (32) via which a transmission signal (Rx) is supplied to the line. Output potentials (TV, RV) of the two amplifiers determine a loop current (IL) on the line, which is monitored and used to control a supply voltage (CV) for the drive circuit, the amplifier output potentials being offset from the supply potentials by headroom voltages (TH, RH) to accommodate the transmission signal. The resulting current limiting voltage control acts iteratively to converge the supply voltage and a target voltage (TG) which is inversely dependent on an amount by which the loop current exceeds a predetermined value, the rate of convergence being fast for high loop currents for rapid response and slow for small differences to provide stable operation. The headroom voltages can be increased to nearly the supply voltage to reverse the polarity of the d.c. feed while maintaining current limiting.

Title: A spatially distributed sma actuator film
Inventor: MAYNARD RONALD S
IPC: C22C19/03
Filed: 1994-02-24
Granted: 2006-05-09
Abstract: A flexible VLSI film containing shape memory alloy SMA actuator elements (105) and associated control and driver circuitry is wrapped around any bendable element such as a flexible, hollow tube, catheter tube or the like. The SMA actuator elements (105) are thus spatially distributed around the circumference of the bendable element.  The SMA actuator elements (105) are selectively resistively heated with an electric current through associated decode and driver circuitry, thereby causing a portion of the film to contract. The radical distribution of the SMA actuator elements (105) across the surface of the VLSI  actuator film is such that when properly activated, a device sheathed with the VLSI film is capable of executing highly dexterous maneuvers in three-dimensional space, which was not heretofore possible. The actuator elements are self-guided in that control circuitry, decode circuitry and associated microprocessors, including position mapping means are fabricated in VLSI integrally with the SMA actuator elements. Alternatively, a microprocessor controller may be located at a remote location while communicating with associated driver circuitry on the actuator film.
