Patent CA-2141379-A1 (CA)
Inventor: LERMINIAUX CHRISTIAN
IPC: G02B6/125
Filed: 1995-01-30
Abstract: An integrated optical proximity coupler comprises first and second parallel straight interaction waveguide segments.  First and second end segments are connected to the input ends of the first and second straight waveguide segments, respectively, by means including first and second curved segments, respectively.  The end segments are both the same predetermined size which is determined by conventional optical fibers to which they are to be connected.  To make the device broad banded, one of the straight segments must be narrower than the other.  To reduce device excess loss, the first straight segment and at least part of its respective curved segment are made slightly narrower than the end segments, and the second straight segment and at least part of its respective curved segment are made slightly wider than the end segments. Thus, the required .DELTA..beta. can be obtained without making the narrow path too narrow.

Title: Method and an apparatus for the purification of residual products from flue gas purification plants
Inventor: JENSEN BJARNE HENNING
IPC: B01D53/48
Filed: 1995-06-20
Abstract: A method and an apparatus for the purification of residual products from flue gas purification plants are disclosed. Between a wet-desulphurization plant for flue gas and an associated waste water-treatment plant for the purification of the water used in the wet-desulphurization there is inserted a leaching apparatus for the purification of hazardous residual products supplied through a conduit from flue gas purification in dry- and semidry-desulphurization plants by means of waste water supplied through a conduit from the plant. The hazardous residual products supplied through the conduit are admixed with the waste water supplied through the conduit in a container whereupon the mixture is conveyed to a filtration step wherein the soluble salts and leachable heavy metals are separated from the filter cake produced and said filtrate being, through a conduit conveyed to the waste water-treatment plant whereas the leached out filter cake, now in the form of a waste dump-safe residual product, is conveyed to a deposit site through a conduit. Thus, the waste water from the wet-desulphurization plant is reused and the overall water consumption reduced. Furthermore, dump-hazardous residual products are converted into dump-safe deposits thereby reducing waste dump expenses without significant additional treatment cost.

Title: Condition responsive solid-state switch
Inventor: CEDERLIND GREGORY F
IPC: H02J1/00
Filed: 1995-11-14
Abstract: Pulse techniques are used to periodically monitor a desired environmental condition, such as pressure. A solid-state switch is connected between a power source and a load. In the off state of the switch, power from the source drives a timer circuit which supplies a short voltage pulse to a circuit for sensing the environmental condition. At the same time, the pulse is supplied to associated circuitry for temperature compensation, amplification of the resulting sensing circuit signal, and a comparator circuit which determines whether or not a signal of the condition sensed exceeds a predetermined threshold. If such signal exceeds the threshold, the solid-state switch is turned on to connect the voltage source to the load. Turning on the switch results in substantially eliminating the voltage drop between the switch terminals, which previously was used to actuate the timer. Accordingly, a separate timer circuit is provided to periodically open the closed power switch for againevaluating the sensed condition and, if appropriate turn the power switch off.
