Patent CA-2296251-A1 (CA)
Inventor: DELANO CARY L
IPC: H03M3/02
Filed: 1998-07-20
Abstract: L'invention concerne un processeur suréchantillonné (300) de signaux de mise en forme de bruit possédant au moins un étage intégrateur (306) situé dans la boucle. Un étage d'échantillonnage (310) est couplé à l'étage intégrateur. Cet étage d'échantillonnage échantillonne un signal analogique à une fréquence d'échantillonnage. Une logique de définition (318) couplée à l'étage d'échantillonnage reçoit de ce dernier une onde d'impulsion et fait en sorte que les apparitions des transitions de signaux de cette onde d'impulsion s'effectuent avec une séparation supérieure à une première période temporelle et que cette onde puisse, par conséquent, être traitée par, par exemple, un commutateur de puissance (312). Un étage de commutation (312) de la boucle est couplé à la logique de définition. Le processeur (300) de signaux possède un trajet de rétroaction depuis la sortie de l'étage de commutation (312) jusqu'à l'entrée de l'étage intégrateur (306), ce qui permet de fermer la boucle.

Title: Improved package and mail delivery system
Inventor: PHAM THIET
IPC: G06Q30/02
Filed: 1998-07-27
Abstract: At the shipping department of a company, contracted outlets or outlets of delivery companies, information concerning the shipper and receiver are written into a label having a memory, but no controller or energy source. The label has a transmitter and the label makes use of power supplied by RF query signals to fetch the information stored and transmits such information to a label reader located either in a portable recorder or at sorting locations. After the information is written into the label, the label is attached to the package. Upon being picked up, the label on the package is read by a portable recorder which transmits the information to a main computer. The packages are then delivered to local hubs of the receiving outlets where information in the labels of the packages are read and the packages sorted according to the information in the labels on the packages and the packages are then delivered to either a central hub and/or local distribution centers of the destinations, where the labels of the packages are then read and the packages sorted accordingly for ultimate delivery to the receiver. Tracking numbers and other delivery information may be retrieved at any point along the way either by portable recorder or at the sorting centers and transmitted to the main computer for tracking and response to inquiries.
Patent CA-2300031-A1 (CA)
Inventor: CHEN QUINGYUAN
IPC: G01N11/08
Filed: 2000-03-06
Abstract: An improved method and apparatus for determining fluid viscosity comprises conveying substantially fully developed, uni-directional, and undisturbed fluid flow through a differential pressure measurement section and flow rate measuring means connected in line with, but separated from, the differential pressure measurement section. A preceding flow tube section is connected to the inlet of the differential pressure measurement section, and a succeeding flow tube section is connected to the outlet of the differential pressure measurement section so that entrance and exit flow effects are avoided in the measurement section. Differential pressure measured in substantially undisturbed, uni-directional, and fully developed fluid flow results in improved accuracy of viscosity calculation using the Hagen-Poiseuille equation.

Abstract: A rain gutter (eavestrough) trash guard that prevents debris such as leaves, sticks or snow from falling into a gutter, and that is directly attached to a standard gutter by a series of simple adapters. The gutter trash guard comprises a gutter cover or shield shaped from a strip of material to a desired profile, with a front edge curved downward allowing water to flow into the gutter and a rear edge bent inwards to form a lip. The front and rear edges of the gutter trash guard shield are engaged and maintained in place by the outer and inner edges of simple adapters screwed into the standard gutter retainer brackets. The gutter trash guard shield is easily installed by snap-fit connection to the adapter brackets by which it is firmly retained in place. The gutter trash guard shield can be manufactured directly at the same manufacturing site as the standard gutters, using the same material and the same technique of shaping the metal strips by bending on a roll-former or similar device.

Abstract: An assembly (8) of an end-fitting (9) and a flexible pressure pipe (1) which is of a non-bonded structure and comprises a number of layers (2, 3, 4, 5, 7) including at least one layer (5) having a number of helically wound flat metallic tensile armour wires (6) with end parts which, in the assembled condition, are embedded in an anchor (23) consisting of a casting material such as epoxy which is injected into a cavity formed in the end-fitting. The flat wire end parts have at least one twist (25) turning generally around the centreline of the wire. Said twists lock the tensile armour wires firmly in the anchor and therefore provide a greater resistance to axial tensile loads acting on the assembly than has been known before. Furthermore the joint is a simple and cheap structure and can be made in situ.

Title: Process for the production of oxygen and nitrogen
Inventor: AGRAWAL RAKESH
IPC: F25J3/04
Filed: 2001-02-22
Abstract: A process for the production of oxygen and nitrogen is applicable when the oxygen product is withdrawn from a distillation column system as a liquid, pumped to an elevated pressure and warmed at least in part by cooling a suitably pressurized stream. At least a portion of the compressed, purified, and cooled air is introduced to a first of at least three distillation columns. The first distillation column contains at least a condenser at its top, produces at least an oxygen-lean stream from or near its top and a first oxygen-enriched liquid from its bottom. A second distillation column, which contains a reboiler in its bottom, has no condenser, receives at least a portion of nitrogen-enriched liquid as a feed to its top, and produces a first nitrogen-rich vapor stream from its top and a second oxygen-enriched liquid from its bottom. A third distillation column, which contains a reboiler in its bottom, has no condenser, receives at least a portion of nitrogen-enriched liquid as a feed to its top, receives at least said second oxygen-enriched liquid as a feed, and produces a second nitrogen-rich vapor from its top and a liquid oxygen-rich stream from its bottom. The liquid oxygen-rich stream from said third distillation column is elevated in pressure and warmed, at least in part, by indirect heat exchange with a pressurized stream having a nitrogen content greater than or equal to that in the feed air, said pressurized stream being cooled without being subjected to distillation. The second distillation column receives as a feed at least one of (a) a portion of said first oxygen-enriched stream from said first distillation column; or (b) a portion of said cooled pressurized stream. The third distillation column receives as a feed at least one of (a) a portion of said first oxygen-enriched stream from said first distillation column; or (b) a portion of said cooled pressurized stream. In the preferred mode of operation, the first distillation column is at the highest pressure, the third distillation column is at the lowest pressure, and the second distillation column is at an intermediate pressure.
