Granted: 2005-04-12
Abstract: An ignition coil for an internal combustion engine and a method of making the same in which layers of the secondary winding are separated by a non-filtering/non-segregating material embedded in an electrically insulated ignition coil housing. The preferred non-filtering secondary winding separator is a solid filament, non-absorbing/non-adsorbing mesh, such as a nylon mesh. Using the non-filtering/non-segregating secondary winding separator prevents filler damming when an ignition coil housing is manufactured using a vacuum encapsulation and curing process in which an encapsulation compound (e.g. a thermal setting epoxy) has solid additives (e.g. sand fillers). Non-absorbing/non-adsorbing separators are also advantageous because the separators do not alter the chemistry of the encapsulation compound.

Title: A method of purifying gases containing nitrogen oxides and an apparatus for purifying gases in a steam generation boiler
Inventor: HILTUNEN MATTI
IPC: F23C10/20
Filed: 1995-04-12
Granted: 2000-08-08
Abstract: A method of reducing the nitrogen oxide level in the flue gases issuing from combustion units by introduction of reducing agents into contact with gases containing nitrogen oxides in first and second reducing stages, is provided.  The first reducing stage is a non-catalytic stage (e.g. at temperatures over 800 ~C), while the second stage is a catalytic stage (e.g. at temperatures of about 300-400 ~C). A steam generation boiler with improved nitrogen reduction facilities is also provided. The amount of nitrogen oxides in the hot gases is reduced in the combination of the first and second reducing stages while producing steam in a steam generation boiler system, thus resulting in gases essentially free from nitrogen oxides while eliminating the possibility of NH3 (or other reducing agent) slip in the exhausted flue gases. Heat transfers in a convection section are used to establish stabilized temperature conditions for catalytic reduction.

Title: Apparatus and method for dual-zone well production
Inventor: MILLS ROBERT A R
IPC: E21B43/14
Filed: 1998-02-16
Granted: 1999-11-23
Abstract: A method and an apparatus for producing fluid hydrocarbons through a single production tubing string from first and second zones which communicate with a hydrocarbon wellbore is disclosed. The apparatus includes a packer positioned in the wellbore for selectively preventing a flow of fluids through the wellbore from the first zone to the second zone, a production tubing string that extends through the wellbore and is in fluid communication through the packer with the second zone, and first and second pumps for displacing fluid through the production tubing string. The second pump displaces fluid from the lower zone into the production tubing string. A perforated joint is placed in the production tubing string between the second and the first pump. The second pump has a given displacement capacity at a given speed and is of a type that inhibits a flow of fluid in either direction through the pump when it is not pumping fluids from the second zone. The first pump is positioned in the production tubing above the second pump and has a predetermined displacement capacity at the pumping speed which is greater than the capacity of the second pump by the capacity desired to be produced from the first zone. The lower pump meters fluid from the lower zone and the upper pump produces fluids from the well so that both zones are produced simultaneously without fluid loss from either zone regardless of which zone has lower pressure. The means for controlling fluid communication through the packer depends on which zone has higher pressure. The advantage is a simple inexpensive apparatus for efficiently producing hydrocarbons from two production zones with pressure differentials without loss of fluid to either zone. Hydrocarbon production from the well is thereby maximized, stabilized and potentially prolonged.
