Title: Roofing washer-dispensing and fastener-driving machine
Inventor: PAUL SIGISMUND G
IPC: B25B21/00
Filed: 1999-04-12
Granted: 2005-01-11
Abstract: In a roofing washer-dispensing and fastener-driving machine, which has a fastener-feeding tube, a fastener-engaging pawl is mounted operatively to the tube, near its upper end. The pawl is pivotable between a normal position wherein the pawl is arranged to engage a fastener dropped into the tube so as to prevent the fastener from dropping through the tube and a pivoted position wherein the pawl is arranged to disengage from the fastener. An elongate rod is arranged to pivot the pawl from the normal position into the pivoted position when the machine is operated. In the same machine, a magazine adapted to hold a stack of such washers is improved so as to have a bridge mounted pivotably to one of two side walls of the magazine and a cover is mounted adjustably to the bridge, so that the cover in an upwardly adjusted position is inserted into the magazine, above a stack of such washers in the magazine, when the bridge spans the side walls and so that the cover is removed from the magazine when the bridge is pivoted to a position wherein the bridge does not span the side walls. The cover is mounted to the bridge via a rod, along which the cover is movable. In the same machine, a shuttle adapted to be reciprocatingly driven is improved so as to have a transverse groove, in which an elongate brace having a pivot pin at each end is fixed by fasteners so as to bear against the leading and trailing edges of the groove, and a transverse rib adapted to engage the lowermost washer in a stack in the magazine is defined by a removable element.

Title: Modular, high-voltage, three phase recloser assembly
Inventor: MATHER BRIAN D
IPC: H01H33/38
Filed: 1999-05-19
Granted: 2004-08-17
Abstract: In accordance with the present invention, a recloser assembly including three modular recloser units operating under the control of a controller. The recloser units are interchangeable and are suitable for use in a three phase power distribution system where three phase tripping is desired or each recloser unit may be operated independently as in a single phase power distribution system. For use in a three phase system, a gang rod mechanically couples pivoting actuation levers extending from a solenoid switching assembly of each of the recloser units. The gang rod insures that all three switching assemblies open and close in unison, thus, each power is transmitted by all three recloser units or power is not transmitted by any of the three recloser units. For single phase power distribution operation, the gang rod is removed and the recloser units operate independently. Each recloser unit includes a cube shaped base, a tapered cylindrical support affixed to an upper surface of the base. The support includes a first opening to receive a ceramic insulator supporting a switch terminal and a second threaded opening to receive a bushing and polymer insulator supporting a line terminal. Each recloser unit utilizes a vacuum interrupter switch or terminal contact assembly to contain electrical arcing and maximize terminal contact life. The interior region defined by each support is filled with an environmentally friendly, nonvolatile insulation material. An interior region of each base houses a solenoid switch assembly and a pressure equalization assembly.

Granted: 2006-09-05
Abstract: An exhaust gas stream containing oxides of nitrogen and sulfur from a fossil fuel fired boiler, a fired process heater, or a chemical process are diverted from a stack prior to emission to the atmosphere through a duct system to a mixer where an oxidant, such as ozone, is added to the exhaust gas at a preselected molar ratio for a preselected residence time to transform the oxides to higher order nitrogen oxides. The oxidized contaminants are treated with a reagent solution. The reagent solution absorbs the oxidized contaminants and unreacted oxidant in the exhaust gas stream. Nitrogen and sulfur oxides in the gas steam are transformed to dilute acids which are neutralized to form salts suitable for discharge to a municipal waste water treatment plant or landfill disposal. The salt solution is also useful as a fertilizer or in the manufacture of fertilizers. The treated exhaust gas is then emitted from an exhaust stack containing NO x and SO x contaminants at a ppm level meeting required air quality standards.

Title: Plastic sewage pipe
Inventor: PRESBY DAVID
IPC: E03F3/04
Filed: 2000-03-14
Granted: 2006-12-19
Abstract: This invention relates to systems for leaching liquid waste, particularly waste water. More particularly this invention is a specially designed cylindrical conduit or pipe for use in leaching systems. The pipe further has axially directed cuts or apertures in conduit/pipe valleys has specially configured ridges, channels and grooves over which may be layed either single or multiple layers of fabric. The corrugated pipe may have slots or slits or V- grooves in and on the various portions of the pipe such as the outer-facing surface of the ridges, the end portion of the ridges, the side wall of the groove or through the bottom portion of the groove, i.e., the valleys. The cylindrical conduit disperses moisture away from the conduit through capillary action, wicking into a surrounding material. A perforated cylindrical conduit is one method permitting wicking. The surrounding material provides capillary action to transmit moisture away from the cylinder or conduit. These surrounding materials include sand, gravel, plastic fibers, wood products, slag, and ash. A fabric or other material may surround the cylindrical conduit. For septic systems, this includes any gravel-less systems such as the SB2, Enviro- Septic and Geo-Flow systems. Other applications of this invention include treatment of oil-contaminated water and chemically contaminated water, in addtion to septic tank effluent.

Abstract: A method for checking the accuracy of an oxygen sensor based determination of the alcohol content of the fuel of a flexible fueled vehicle. Following the addition of fuel to the flexible fueled vehicle two alcohol concentration possibilities are calculated. The two alcohol concentration possibilities are then used to calculate thresholds for the determining if the oxygen sensor based determination falls within the thresholds. If the oxygen sensor based determination does not fall within the thresholds then action is taken to counteract an inaccurate determination of alcohol concentration.
