Patent CA-2050412-A1 (CA)
Title: Flow control device
Inventor: HAMMER MICHAEL R
IPC: G01N21/72
Filed: 1991-08-30
Abstract: A method and means for accurately regulating the rate of flow of supply gas to the burner or torch of a spectrometer.      The flow rate is controlled by a valve having a closure member which is movable between a position at which it provides maximum obstruction to gas flow, and a position at which it provides minimum such obstruction. The closure member movement is controlled by a pulsed electrical signal so that the closure member moves rapidly and repeatedly between each of the two positions. Gas flow rate through the valve is therefore dependent upon the aggregate of the times the closure member spends in either of the two positions referred to, and that flow rate is changed by varying the frequency and/or pulse duration of the pulsed signal.

IPC: C12P1/00
Filed: 1992-04-16
Abstract: Enzymatic dehalogenation of undesirable nitrogen-free organohalogen compounds is carried out by adding a dehalogenase to an aqueous composition comprising a nitrogen-free organohalogen compound and a nitrogen-containing cationic polymer. The enzymatic dehalogenation of the nitrogen-free organohalogen compound is achieved without any substantial effect upon the nitrogen-free organohalogen compound. The dehalogenation method may be carried out via continuous, batch, or semi-continuous processes.      The composition is especially useful as a paper wet strengthening formulation, and is useful in commercial papermaking processes. The resulting paper product comprises a residue of a microorganism.  Preferably the enzyme is obtained from a biocatalyst, still more preferably from a microorganism. Batch-enrichment of a culture of a dehalogenase-containing microorganism provides a composition capable of substantially eliminating the presence of nitrogen-free organohalogen compounds, which are considered to be pollutants. Cell concentrations of greater than 5 x 10 7 cells/ml are provided.

Filed: 1991-08-22
Abstract: A snow making apparatus comprising a housing defining a bore (14) which is open at least at one end and having first and second annular chambers (38, 32) which extend circumferentially of the bore. The first and second chambers (38, 32) are respectively connectable to a source of pressurised water and of pressurised air. A  circumferential array of outlets (42) from the first chamber (38) are operable with pressurised water supplied by chamber (38) to direct water jets along and towards the axis of the bore. A  circumferential array of passages (36) provide communication between the second chamber (32) and the bore (14), each passage (36) opening towards or beyond the one end of the bore (14). The passages (36) discharge pressurised air supplied to the second chamber (32) as a plurality of air jets directed towards or beyond the one end of the bore (14), to generate a flow of air which passes beyond the one end of the bore (14). In use, the water jets impinge on the air jets to thereby generate snow particles which are carried axially beyond the one end of the bore (14).

Filed: 1993-04-06
Abstract: A bulk memory (30) stores a data base (BDT) representing at least one substantial part of the terrestrial globe, according to a meshing with several levels, which is more precise especially in the vicinity of an airport. Status indications are received, representing the position of the aircraft, with two horizontal components (L, G) and the altitude (Z), and the speed and acceleration vectors of the aircraft, as well as control indications (MZC) originating from the control position. As a function of the said horizontal components of the position of the aircraft, means (35) transfer into high-speed memory (40) a temporary local card, from which there is defined an envelope in terms of the altitude of the terrain, in the region in which the aircraft is moving. Anti-collision processing means (4; 43, 46) make it possible to give an alarm (51) if the relationship between a protection domain and the altitude envelope satisfies a first condition which is defined at least partly by the said control indications. <IMAGE>

Title: Method and apparatus for refrigerant recovery
Inventor: SEVRAIN CHRISTOPHE J
IPC: F04B49/06
Filed: 1993-05-04
Abstract: METHOD AND APPARATUS FOR REFRIGERANT RECOVERY           Abstract of the Disclosure Refrigerant is recovered using a single pump unit, regardless of the refrigerant's phase.  This is achieved by sensing the phase of the refrigerant and changing the pump's operation accordingly.  The refrigerant phase can be sensed by a temperature-responsive element, such as a thermistor, or by other phase-sensing technology.  In a preferred embodiment, the pump unit is a vane pump whose rotational speed is changed in response to the refrigerant's phase.  If liquid refrigerant is sensed, the pump operates at a lower speed.  If gas refrigerant is sensed, the pump operates at a higher speed.  The two speeds are chosen so that the pump will draw an EPA-specified vacuum on the refrigerant present. In other vane-pump embodiments, the pump's operation is changed by changing the pump's mechanical configuration, rather than its rotational speed.

Title: Exhaust vent
Inventor: WALTZ ARTHUR L
IPC: E04D13/17
Filed: 1993-12-10
Abstract: A novel ventilator having a one-piece plastic base with integral tubular member having a through passageway for flow of an exhaust gas stream. The tubular member is preferably molded simultaneously with the base, rather than glued, so that the base and tubular member assembly comprise not only a sealed tubular member, but provide a single, seamless part. Thus, moist air cannot leak out of the air flow path between the interior and exterior of a wall or roof. The ventilator is also provided with a screen and a flapper type lid for the tubular member.      The flapper lid seals the outer end of the tubular member against inflow of outside air at those times when there is no exhaust gas stream impinging against the flapper so as to keep the flapper in the open position.      The ventilator may be provided in a variety of colors by pigmentation of the plastic to be molded into the ventilator.
