Patent CA-2063242-C (CA)
Title: Hydraulic machine
Inventor: PEARCE RONALD JAMES
IPC: E04H4/16
Filed: 1992-03-17
Granted: 1998-08-25
Abstract: The invention concerns an hydraulic machine, typically a submerged surface cleaner which comprises a body having a liquid inlet and a liquid outlet and a conduit extending between the inlet and the outlet. A drive element is supported in or adjacent to the conduit, with a clearance between the drive element and the interior of the conduit, in a manner permitting eccentric location and rotation of the drive element relative to the conduit. The conduit can be connected in a liquid flow path so that liquid passing through the conduit past the drive element, when the drive element is positionedeccentrically relative to the conduit, applies differential forces to the drive element to cause it to rotate relative the conduit. The rotation of the drive element is used directly or indirectly to drive the cleaner over a submerged surface.

Title: Non-intrusive flow meter for the liquid component of two phase flow based on solid, liquid or gas borne sound
Inventor: WOLF HENRY ALAN
IPC: G01F1/66
Filed: 1992-05-22
Granted: 2001-10-16
Abstract: .      The method includes determining the Power Spectral Density from the output of an accelerometer in close proximity to the restric-tion orifice controlling the gas flow, or determining the Power Spectral Density from the output of a pressure transducer in contact with the gas flow on the down stream side of the restriction orifice.      The liquid flow can then be obtained from a predetermined correlation between the RMS Vibrational Signal and the mass or liquid flow rate.

The further webs of the hollow marginal section are composed by an approximately U-shaped section with two U-limbs and a crosspiece.      The edges of the U-limbs are overlapped by the abutment web and at least one U-limb, suitably the U-limb remote from the lining skin, is firmly connected, e.g, welded, to the abutment web. The abutment web has a fastening flange engaging, particularly lapping over the side of the lining skin facing the concrete, but at the same time suitably recessed into the lining skin. A groove receiving and embracing the edge of the lining skin therein is formed by the flange together with the fastening web of the marginal section and the intermediate portion of the abutment web, said fastening web being composed by the U-limb closest to the lining skin and in the position of use contacting the side of the lining skin facing away from the concrete.

Title: Transmitted noise reduction in communications systems
Inventor: WYNN WOODSON DALE
IPC: G10L21/0208
Filed: 1994-11-15
Granted: 2000-12-19
Abstract: A telecommunications network service (figure 1) overcomes the annoying effects of transmitted noise by a signal processing which filters out the noise using interactive estimations of a linear predictive coding speech model. The speech model filter uses an accurate updated estimate of the current noise power spectral density, based upon incoming signal frame samples which are determined by a voice activity detector (25) to be noise-only frames. A novel method of calculating the incoming signal using the linear predictive coding model provides for making intraframe iterations of the present frame based upon a selected number of recent past frames and up to two future frames (figure 3 and figure 10). The processing is effective notwithstanding that the noise signal is not ascertainable from its source.

Abstract: A closed shot die casting metal delivery system having a rotary actuated closure member.  The system includes a shot sleeve having a bore and a transverse fill hole communicating with the bore.  A closure member is rotatably mounted on the shot sleeve and defines a window.   The closure member rotates between a fill position in which the window is aligned with the filling hole and a casting position in which the closure member seals the filling hole.  Any excess molten material from the fill is poured from the closure member as it rotates.   In the preferred embodiment, the closure member is mounted eccentrically with respect  to,  and intersects, the bore.  In this case, the closure member defines an arcuate recess that aligns with the internal bore when the closure member is in the casting position, thereby allowing the plunger to reciprocate through the internal bore.

Title: Method and apparatus for direct oxygen injection with a reactant stream into a fluidized bed reactor
Inventor: WAGNER MATTHEW LINCOLN
IPC: B01F23/10
Filed: 1996-08-23
Granted: 2002-01-15
Abstract: A system provides an oxygen-bearing gas and a gaseous reactant stream to a fluidized bed reactor. A sparger causes an entraining of the oxygen bearing gas into the reactant gas stream. A feed line couples the sparger to the reactor's fluidized bed and introduces the reactant gas stream and entrained oxygen-bearing gas directly into contact with the fluidized bed. A controller controls both the amount of oxygen-bearing gas and the gaseous reactant so that, at the point of feed injection, the fluidized bed catalyst does not experience an oxygen deficiency. To assure safety, the reactant content of the combined feed and oxygen stream is maintained above an upper flammability limit, preferably with a safety margin of at least 25%. In one embodiment, the system enables the production of acrylonitriles from a feed stream comprising ammonia, propylene and oxygen.

Abstract: An improved process is disclosed for manufacturing chlorinated hydrocarbon by way of a once-through air-based oxychlorination process which yields reduced levels of environmental toxins such as chlorobenzenes, polychlorinated biphenyls, polychlorinated dibenzodioxins and polychlorinated dibenzofurans. The process involves fixed bed or fluid bed catalyzed oxychlorination of a hydrocarbon reactant containing from 1 to 3 carbon atoms.      The oxychlorination process consists of contacting the hydrocarbon reactant with air or oxygen enriched air and hydrogen chloride in the presence of the oxychlorination catalyst in a heated reaction zone operated at from 150°C to 600°C and recovering chlorinated hydrocarbon from the effluents of the reaction zone. The improvement consists of the use of air which is pretreated before use in the operated oxychlorination process by a means for removal of the aromatic hydrocarbons.
