Abstract: A thin film mem-brane filtration system (50) recovers particulate from the waste water stream (66) of a wood panel fabrica-tion process to a desired concentration of approxi-mately 30-50 % solid by weight. The high concen-tration level enables im-proved transport or dispo-sal. Rather than discard the concentrate, however, the concentrate is added into subsequent wood pan-el "particle board" batches at a rate of approximately 0.5 to 0.65 gallons per 1000 pounds of wood pro-duct. The concentrate re-duces press time, serves as a scavenger for tying up formaldehyde and serves as a resin extender for strengthening internal bonds of fabricated pan-els. The membranes (54) capture the particulate into an accumulated concentrate, while passing permeate output to a recycle water stream (80).

Abstract: An arrangement for controlling a large time slot interchange (TSI) unit. The TSI unit is a single stage unit for interconnecting any incoming time slot with any outgoing time slot.  No blockage is incurred in such a single stage switch.  A plurality of module processors is used each for controlling a group of TSI slices, the size of the group being selected to match the capabilities of the module processor. The module processors communicate with each other in order to cooperate in setting up connections through the TSI unit.  Each module processor processes terminating, originating, incoming or outgoing processes for calls connected to the terminalsserved by the module processor.  Advantageously, a large non-blocking TSI unit is made available for serving a large switching system without incurring blockage. Moreover, the TSI unit and its complement of module processors can be arranged to grow in a cost effective manner from a relatively small unit to a unit that is near the largest size practical switching system.

Abstract: A water jet edge trimming station for trimming the edges of coated paper during on-machine operation includes backsplash compensating features. The edge trimming station has a cutting station over which the web travels to be cut. The water jet travels along a water jet axis to a point of impingement at the cutting station to cut the web. The cutting station has an effluent receiving aperture at the point of impingement. A negative pressure mixing zone located below the aperture draws effluent by-products or backsplash associated with cutting of the web below the cutting surface of the web. The water jet axis is offset a first predetermined angle chosen relative to a normal axis passing at right angles through the point of impingement to reduce backsplash. The water axis jet is rotated about the normal axis by a second predetermined angle to direct the effluent by-products away from the water jet nozzle and the traveling web. The water jet cutting apparatus has positive air pressure chamber surrounding the nozzle head of the water jet to maintain an air flow over the nozzle head driving effluent backsplash away from the nozzle head.

Patent CA-2211987-C (CA)
Inventor: WAYNE RAMON
IPC: A47K3/12
Filed: 1997-09-29
Granted: 2000-08-08
Abstract: The invention relates to an adjustable, wall-mounted, shower-enclosure, support apparatus, adapted to provide, when required, enhanced protection against injury, through loss of balance, to a bather, using the shower in a bathtub-shower combination unit or, alternatively, a separate shower stall.     A bather who loses balance, for any reason, while taking a shower, is liable to fall in any direction. Yet, wall-mounted grab-bars in a shower-enclosure, generally, provide protection against that risk in only one or two directions.       To overcome that deficiency, the invention provides for an apparatus which incorporates a body-encompassing frame member that can surround the bather at a chosen height, when required, and thereby supply, in all directions within a horizontal plane, a reliable means of support which can be seized in an emergency or which can break a fall under certain circumstances, when the support cannot be used as intended.

Title: Analyseur de gaz optique a correlation
Inventor: IVANOV EVGENIY VLADIMIROVICH
IPC: G01N21/35
Filed: 1996-03-20
Granted: 2001-06-12
Abstract: La présente invention concerne un analyseur optique de gaz, qui comprend des systèmes optiques, mécaniques et électroniques. Le système optique comporte un collimateur, un filtre de lumière, un filtre à polarisation à interférence modulée (IPF) et un détecteur photoélectrique. L'IPF modulé a deux polariseurs, croisés ou parallèles, un modulateur optique et une plaque biréfringente étant montés entre eux. La plaque biréfringente a une épaisseur variable à entraînement mécanique et est commandée par le système électronique, par l'intermédiaire du pilote électromécanique. Le détecteur photoélectrique est placé après l'IPF et sa sortie est reliée au système électronique. L'analyseur de gaz selon l'invention a l'avantage de permettre d'abaisser la limite du minimum détectable de concentration du gaz mesuré, par une réduction sensible de l'influence de la modulation parasite. Celle-ci est induite par le modulateur optique dans les unités optiques et électroniques de l'analyseur de gaz, et affecte le signal de sortie. Cependant, la modulation synchrone de l'IPF modulé annule l'effet parasite à la sortie finale, effet fondé sur la différence entre deux mesures de ce genre.

Filed: 1998-03-02
Granted: 2001-04-17
Abstract: This invention is an advanced method for determining formation density in an array-detector density tool. The use of three or more detectors yields an improved accuracy and precision of the formation density measurement even in the presence of a large standoff between the tool and the formation. A more accurate photoelectric factor is determined through a new single detector algorithm. Use of the information on the photoelectric effect and the density from the three detectors allows the measurement of a photoelectric effect compensated for stand off and the photoelectric factor of the mudcake. The use of the multi-detector density answers allows for a consistency check and therefore a much improved quality control of the density measurement.
