Patent CA-2321937-A1 (CA)
Inventor: SPIEL NORTON
IPC: B29C53/12
Filed: 2000-10-02
Abstract: A combination book binding machine with a plastic coil forming machine, whereby a plastic spiral coil is formed at a first raised temperature, then cut to a length sufficient for the plastic spiral coil to bind a book, cooled and then advanced toward a receiving coil conveyor of a coil binding machine, for binding the book with a plastic coil at the lowered cooled temperature. The binding machine and method for spirally binding a sheaf of papers into a book uses an adjustable speed drive to rotate the cooled flexible plastic spiral coil into respective holes in the book. The book has a plurality of holes in a row adjacent one edge of the book to receive the leading edge of the plastic spiral binding coils. A cylindrically shaped mandrel is spaced apart from a glidable block. The plastic pre-formed spiral binding coil is fed onto the mandrel from the distal end thereof, with the leading edge of the binding element facing and spaced apart from the book. A pair of leading edge spreaders, one of which has a guidance groove, engages the plastic spiral coil to spread its joined coil portions just enough to permit the coil to enter the successive holes of a sheaf to be bound. A  trailing spreader at the opposite end insures that the last hole is accommodated with a portion of the plastic spiral coil.

Abstract: An apparatus and method for recycling drilling mud contaminated with particulates, consists of channelling a stream of contaminated slurry onto a screen deck, with the partly cleansed liquid entering a mixing tank. Liquid within the tank is continually mixed. An exit conduit removes liquid from the tank on a continuous basis, where it is given an additional purification with a cyclonic separator. The heavier fraction is further screened, with the resulting purified liquid reentering the tank. The lighter fraction exists the cyclonic separator, and a portion of the lighter liquid is withdrawn for use as a substantially cleansed liquid. Another portion of the lighter fraction is re-circulated back into the tank, thus providing multi passes through the system to provide enhanced purification. The cleansed liquid may be directed into a separate mixing apparatus, in which additional slurry-forming powder such as Bentonite is added for forming a new slurry.

Patent CA-2326644-A1 (CA)
Inventor: LEHMAN JOHN A
IPC: H01S5/022
Filed: 1999-03-29
Abstract: A rigid alignment of a fixture connection to a chip (28) having the rigidity of the connection transferred from the chip to a chip holder (19). The chip has an alignment feature (29) that has a specific position relative to a device (12) on the chip to which another device (20) of a fixture is to be aligned. An alignment fixture has an alignment feature and a device site which aligns with the alignment feature and the device on the chip, respectively. The alignment fixture has a fastener on the chip holder. The chip is moveable on the holder and is moved until the alignment features of the fixture are aligned, which also results in the alignment of the device site with the device. The chip is attached with glue or solder (43) to the holder. The alignment fixture is removed and substituted with a connector interface fixture having no alignment feature relative to the chip but rather an alignment mechanism to the block that the chip is attached. The device and a fastener of the connector interface fixture have the same relative positions as the device site and fastener, respectively, of the alignment fixture. Attaching the fastener of the device fixture to the fastener on the chip holder results in passive alignment of the devices on the fixture and the chip, as the fasteners are likened to an alignment mechanism or features. Stresses applied to the device fixture are transferred to the chip holder via the fastener, and not to the chip.

Title: System and method for scheduling message transmission and processing in a digital data network
Inventor: FOLLETT DAVID R
IPC: H04L12/56
Filed: 1999-04-23
Abstract: A system includes a plurality of computers interconnected by a network including one or more switching nodes. The computers transfer messages over virtual circuits established thereamong. A computer, as a source computer for one or more virtual circuit(s), schedules transmission of messages on a round-robin basis as among the virtual circuits for which it is source computer. Each switching node which forms part of a path for respective virtual circuits also forwards messages for virtual circuits in a round-robin manner, and, a computer, as a destination computer for one or more virtual circuit(s), schedules processing of received messages in a round-robin manner. Round-robin transmission, forwarding and processing at the destination provides a degree of fairness in message transmission as among the virtual circuits established over the network.  In addition, messages are transmitted in one or more cells, with the round-robin transmission being on a cell basis, so as to reduce delays which may occur for short messages if a long messages were transmitted in full for one virtual circuit before beginning transmission of a short message for another virtual circuit. For each virtual circuit, the destination computer and each switching node along the path for the virtual circuit can generate a virtual circuit flow control message for transmission to the source computer to temporarily limit transmission over the virtual circuit if the amount of resources being taken up by messages for the virtual circuit exceeds predetermined thresholds, further providing fairness as among the virtual circuits. In addition, each switching node or computer can generate link flow control messages for transmission to neighboring devices in the network to temporarily limit transmission thereto if the amount of resources taken up by all virtual circuits exceeds predetermined thresholds, so as to reduce the likelihood of message loss.

Abstract: A support bracket for a locator wire prevents loss of the end of the locator wire which is buried with a utility gas line. In a typical application, a gas line enters a riser pipe prior to emerging from the ground surface. The riser pipe supports a gas valve and gas meter above the ground. A locator wire is buried in the ground adjacent to the gas line. In a first version of the invention, an elongated tube body is oriented vertically, and defines a passage through which the locator wire extends immediately above and below the surface of the ground. Lower and middle fastening clamps, one each located above and below ground, secure the elongated tube body to the riser pipe. An upper fastening clamp secures an upper portion of the elongated tube body to the riser pipe, and also secures the end of the locater wire. A second version of the invention is similar, but is manufactured in an integral manner with the riser pipe. A third version is adapted for attachment to route markers, in a manner similar to the attachment of the first two versions to the riser pipe.

Title: Method and device for detecting analytes in fluids
Inventor: CARPENTER CHARLES R
IPC: C12M1/34
Filed: 2000-03-24
Abstract: A disposable, dry chemistry analytical system is disclosed which is broadly useful for the detection of a variety of analytes present in biological fluids such as whole blood, serum, plasma, urine and cerebral spinal fluid. The invention discloses the use of the reaction interface that forms between two liquids converging from opposite directions within a bibulous material. The discovery comprises a significant improvement over prior art disposable, analytical reagent systems in that the detectable reactant zone is visually distinct and separate from the unreacted reagents allowing for the use of reaction indicators exhibiting only minor changes as well as extremely high concentrations of reactants. In addition, staged, multiple reagents can be incorporated. Whole blood can be used as a sample without the need for separate cell separating materials. Finally, the invention is useful for the detection of analytes in a broad variety of materials such as milk, environmental samples, and other samples containing target analytes.
