Abstract: A water fowl (e.g. duck) decoy system in which the decoy's wings (20/120), which are flat and both longitudinally and laterally extended by, for example, having one or more, curved lobes (23/123A&B, note FIGS. 1& 5B), producing a disc like shape, preferably of a size of at least about nine (9″) inches in “diameter,” with contrasting colors (e.g., dark olive & white; cf. FIGS. 5B & 5C) on its flat sides with one or more stripes on its lighter side, are rotated at a relatively high speed (e.g., ˜600 rpm+, e.g., more particularly ˜600 or ˜750 rpm or up to ˜900 rpm or greater), producing a “strobe” like effect for enhanced visibility of the decoy to flying ducks. Additionally, the decoy (1/101) has a laterally disposed, direct, in-line, DC electric motor drive (30), with laterally directed, dual shaft connectors (note FIG. 3) directly connected to the wings.

Abstract: A drain alert device for detecting an overflow condition in a drainage system having a drain conduit, wherein wastewater is received through an inlet of the drain conduit, is provided, comprising an overflow conduit extending horizontally from the drain conduit below the inlet. The overflow conduit leads to an overflow detection device which includes a vessel having an internal volume sufficient to contain an amount of overflow wastewater. A buoyant member having an elongated, substantially vertical, overflow indicator resides within the vessel, and the overflow indicator is guided by a guide tube extending above the vessel. Thus, the overflow indicator reveals the extent of an overflow condition by protruding through the guide tube in response to the level of wastewater within the vessel. The vessel further includes a drain port having a threaded coupling capable of receiving a conventional flexible hose so that the appliance may be operated despite obstructions in the drain conduit.

Abstract: A method and apparatus for determining the thermal capacity of overhead power lines is disclosed. The apparatus includes two rods of similar diameter and material properties to the line to be rated. One of the rods has a heater inside that dissipates a known amount of energy approximately equal to what the line loses during operation at the static rating. The rods are oriented parallel to the line and the temperature of each is measured. Using this information and standard equations governing the cooling of power lines, a very accurate, real-time reading of the line's thermal capacity is generated.

Abstract: A passive warning system for communicating vehicular deceleration and other information through a warning light. A microprocessor-based warning system according to the invention accounts for variations in vehicular speed in generating a warning signal having an intensity level and a blinking rate related to the rate of deceleration of the automobile, the ambient driving conditions and the speed of the automobile. The microprocessor is also programmed to measure speed variations more frequently as the speed of the vehicle increases, allowing information to be communicated in a timely manner. In one embodiment of the invention, the microprocessor is programmed to maintain the highest intensity warning signal activated for a predetermined period of time in order to inform other vehicles of an earlier speed reduction.

Abstract: A method of purifying an aqueous liquid stream is provided, wherein the liquid stream is pressurized and contains proteinaceous materials, such as blood, and suspended solids, comprising the introduction of carbon dioxide into the liquid stream in a manner to reduce the pH of the liquid stream sufficient to cause coagulation ofthe proteinaceous materials. Specifically, it is intended that the pH of the liquid stream is reduced to a level below the isoelectric point of the proteinaceous materials, preferably at a level below pH 4.5. In a preferred method, the liquid stream is moved by a dissolved gas pump, wherein the carbon dioxide is introduced into the dissolved gas pump, and wherein a first portion of the gas is caused to dissolve within the liquid stream, and a second portion of the gas is caused to entrain within the liquid stream in the form of micro-fine bubbles.

Abstract: A device for the treatment of wastewater is provided. The basic device includes a wastewater inlet, a connecting means and a bioreactor. The bioreactor is a substantially water-tight compartment which has its bioreactor inlet fluidly connected to the connecting means which is fluidly connected to the wastewater inlet.

The administration server transmits data received from one network member to one or more other network members.

Abstract: A clothes hanger extender which attaches to standard plastic clothes hanger so as to be able to adjust for different sized garments. The channel end has a hollow interior with a substantially elliptical cross section. The first portion of the channel, the channel locking portion, has a locking portion width which is smaller than the channel end's interior diameter. The second portion of the channel, the channel transition portion, connects the channel locking portion with the channel adjustment portion to make a continuous channel. The last portion of the channel is the channel adjustment portion. The channel adjustment portion allows the clothes hanger extender to slide over a standard plastic clothes hanger. The channel adjustment portion alternatively terminates at the shoulder end, or is the shoulder end, depending upon whether the shoulder end is a separate component.

Abstract: A novel chromatograph is provided. The chromatograph includes an analytical column which is a channel with a rectangular cross-section. Integrated with the chromatograph are a sample collection channel and a restriction channel. The column, sample collection channel, and restriction are all part of a single unitary microstructure. The microstructure is manufactured by irradiating and etching a material subject to synchronized x-ray radiation. The device will either be made of the actual etched material, or the etched material will be used as a mold or model to fabricate the chromatograph. A method of using the device is also disclosed.

Abstract: An on-board treatment device and method for use on watercraft and other mobile vessels are provided. The system includes a treatment tank which is connected to the head and a bioreactor and a feed pump which are connected to the treatment tank. A macerator pump breaks up solids in the wastewater before the wastewater enters the treatment tank. During a treatment cycle, a head valve prevents any further flow of wastewater from the head into the treatment tank. Also during a treatment cycle, a bioreactor 3-way valve will be set so that the feed pump will flow wastewater from the tank, through the bioreactor, and back into the treatment tank. The bioreactor will include microorganisms which are adapted to the treatment of human waste. When the wastewater has been sufficiently treated, the feed pump will be turned off so that solids in the wastewater can settle out.

Abstract: A gas chromatograph and method of chromatography are provided. Analytes, those compounds to be tested, are extracted from the sample by moving the sample into a column which has a stationary phase along the column walls. The column has two sections which are different in length. The longer section is heated and the analytes move to the shorter section. The longer section is then cooled and the entire column is heated. The device then functions as an analytical column and the analytes move out of the shorter section, through the longer section, and out of the column. A detector placed at the end of the column's longer section detects the presence of the compounds as they exit the column. In an alternate embodiment two separate columns are provided. One column is used as the extraction column and the other is used as the analytical column.
