Patent CA-2153834-A1 (CA)
Inventor: MORAVA IRENA
IPC: H02G7/20
Filed: 1995-07-13
Abstract: Coaxially sheathed single core conductors are employed in this power  distribution  system.  A current  of  equal  magnitude  and opposite in direction to that flowing in each core conductor is fed back through the coaxial sheath of that conductor so as to create a neutralizing magnetic field generated by the current flowing through each core conductor to result in effectively no magnetic field emitting from the distribution lines. It also reduces line reactance to provide more even current distribution of the current amongst the parallel conductors.

Title: Improved methods and systems for subterranean multilateral well drilling and completion
Inventor: LONGBOTTOM JAMES R
IPC: E21B29/06
Filed: 1995-08-25
Abstract: Improved methods and systems for creating a multilateral well and improved multilateral well structures. In one aspect of the present invention, the method comprises the steps of: (1) setting a diverter at a prescribed position and a prescribed orientation in a main well flow conductor located within a main wellbore, (2) boring through a sidewall of the main well flow conductor and into a material surrounding the main well flow conductor, the boring creating a window having a particular shape in the sidewall, the orientation of the diverter determining a lateral position of the window in the main well flow conductor, a lateral wellbore thereby being formed in the material and extending from the main wellbore, (3) lining the lateral wellbore with a liner, the liner having an interface end, the interface end adapted to contact a periphery of the window in the sidewall and (4) cementing the liner in place within the lateral wellbore, the step of cementing creating a pressure-bearing seal between the periphery of the window and the interface end of the liner. The method allows multiple lateral wellbores to be joined to the main wellbore and provides for connectivity among main and lateral wellbores, pressure-bearing sealing of joints to allow selective isolation of one or more wellbores or portions thereof and subsequent wellbore access for rework or other purposes.

Abstract: The invention provides methods and compositions for increasing the availability of soluble phosphate and fixed nitrogen for legume: Rhizobium symbioses involving co-inoculating legume seeds with a phosphate-solubilizing soil fungus, Penicillium bilaii, and Rhizobium spp. prior to planting.   The two types of microorganisms  do not appear to compete for nutrients in the rhizosphere of legumes and the P. bilaii provides a source of available phosphorus for use by the plant without adversely affecting the nitrogen fixation ability of the Rhizobium spp.; and indeed such ability is enhanced.  The invention is used to increase the efficiencies of nodulation, nitrogen fixation and legume crop production.

Title: Laminar flow electrostatic precipitation system
Inventor: FELDMAN PAUL L
IPC: B03C3/49
Filed: 1996-08-06
Abstract: An electrostatic precipitation system (100) utilizes laminar flow of a particulate-laden gas in order to enhance the removal of sub-micron sized particulates.          The system incorporates a housing (105) through which the gas flows to an outlet port (110).  The gas, which may be a flue gas enters the laminar flow precipitator (102) through an inlet port (108) for passage through a charging section (104).  The flue gas and charged particles then flow to a collecting section (106). The collected particulates are subsequently collected in a hopper (112) or reentrained in the gas stream as agglomerates for subsequent removal by a secondary filter (120), the gas stream then being conveyed to a stack (14) wherein the particulate-free gas can be emitted into the atmosphere.

Title: Vertically adjustable sun-visor
Inventor: SZOKE BELA BILL
IPC: B60J3/02
Filed: 1997-02-07
Abstract: A Vertically Adjustable Sun-visor enables a driver of an automobile to lower the elevation of the unit by widening its width in addition to axial rotation to block the sun rays, or opposing traffic lights. Lowering the elevation is achieved by pushing two horizontally mooving sliding bars' arms, which are part of the plate structure, against each other, thereby disengaging both sliding bars outer ends from cavities arranged vertically, at the inside sides of the enclosure, thereby the enclosure falls to lower elevation by the force of gravity. When releasing the pressure on the arms, the spring loaded sliding bars' teeth thrust into cavities at the new elevation. Decreasing the width of the Sun-visor produce higher elevation which is achieved by simply pushing upward the enclosure to a desired elevation, where the spring loaded sliding bars' teeth could trust into the vertically arranged cavities to stabilize the elevation.
