Title: Point-to-multipoint connections
Inventor: NOVAK LARS
IPC: H04M3/42
Filed: 1996-03-11
Abstract: This invention relates to distributive services in telecommunications networks, and in particular to methods for establishing point-to-multipoint connections and multipoint-to-point connections as well as to methods of releasing these types of connections. Program distribution to several subscribers (S3, S4) uses network resources in common along common call routes. A list (58) of potential program distribution points (D5, D6, D7) is created and a running index is associated with each one of the distribution points.      Before a connection is set up to a subscriber (for example S4) the list is examined and a distribution point (D6) is selected from which a point-to-point connection (62) is set up to the subscriber. The running index is stepped up. The running index of a distribution point is stepped down during release of a connection (62) and is examined in connection with release of a call route section (61).
Patent CA-2216798-A1 (CA)
Title: Use of sized salts as bridging agent for oil based fluids
Inventor: GABRYSCH ALLEN
IPC: C09K8/36
Filed: 1996-03-25
Abstract: An oil-based fluid system has been discovered using a distribution of salt particle sizes, an oil or water/oil emulsion, a suspending agent for suspending the salt particles in the oil and a filtration control agent. It is important that the salt particles be distributed across a wide size range to effectively prevent filtration or fluid loss into the formation. Since the filter cake particles do not invade the well bore. no high pressure spike occurs during the removal of the filter cake. This high pressure spike indicates damage to the formation and well bore surface, which damage typically reduces overall permeability of the formation. The rheological properties of the fluid allow it to be used in a number of applications where protection of the original permeable formation is desirable. The applications include, but are not limited to, drilling, fracturing and controlling fluid losses during completions, such as gravel packing or well bore workovers.

Title: Modular and low power ionizer
Inventor: KRAUSE HANS W
IPC: B03C3/72
Filed: 1996-05-31
Abstract: An apparatus for ionizing air to remove particulate matter. The apparatus comprising an ionizer and a bracket for mounting the ionizer in a duct or enclosure. The ionizer includes a series of electrodes which span a portion of the duct. The electrodes are energized by a high voltage circuit and an ionic wind is created between the electrode and duct. The ionic wind sweeps particles in the air to the duct which provides a collector electrode. In another embodiment, a ring collector electrode is also provided for spanning the inner portion of the duct. The high voltage circuit comprises a DC power supply, a high voltage transformer, a high voltage multiplier stage and a push-pull switching circuit. The DC power supply receives AC power and generates a DC output which is coupled to the primary of the transformer. The push-pull switching circuit produces a controlled and efficient AC output in the transformer by alternately switching the primary winding. The output voltage from the secondary winding is further increased by the multiplier stage to a level sufficient to energize the electrodes and produce the ionic wind. The apparatus also comprises a high voltage multiplier stage.

Title: Bagel dough extractor
Inventor: GERING GEORGE
IPC: A21C15/04
Filed: 1998-01-05
Abstract: An annular base carries a moveable cam member . Downwardly extending circumferentially arranged arcuate blades are mounted along the outer edge of the base to form a circle. Downwardly extending circumferentially arranged arcuate blades are pivotly mounted along the inner edge of the base to form a circle within the circle of fixed blades. Springs are interposed between radially aligned pairs of blades. The apparatus is positioned over the bagel such that the blades enter the interior of the bagel. The cam member cooperates with the moveable blades to move each blade in a substantially radial direction, against the intervening spring. The blades move from a position spaced from the aligned fixed blade to a position proximate to the aligned blade, as the cam member is moved, causing the dough to be pinched between the aligned blades. The dough is extracted as the apparatus is removed from the bagel.

IPC: F23D14/06
Filed: 1998-05-27
Abstract: A gas burner adapted to discharge said fuel at its the periphery for combustion, includes upper and lower concave plates secured together to define a chamber and an outer periphery having a plurality of burner ports. The upper plate preferably has a periphery extending radially at least as far as the lower plate.  The periphery of the upper plate is downwardly angled, preferably more steeply than the periphery of the lower plate.  The peripheral edge of at least one or the other of the top or bottom burner plates extends radially outwardly from the central axis a distance beyond the location of the burner ports and into the path of burning gases issuing from the ports whereby the temperature of said burning gases is reduced.   Preferably,  the periphery of the upper plate extends downwardly to an elevation below the  upper edges of the burner ports,  so that gases emerging from the ports are caused to  impinge  against the   periphery,  thus cooling  the gases  and  thereby  reducing  the  NOx content of the combustion gases.
