The alloy in the present invention consists essentially of, by weight percent, about 0.10 to 0.17 wt % of carbon, from about 0.30 to 2% of silicon, from about 0.30 to about 2% manganese, from about 10% to 20% nickel, from about 20% to about 35% chromium, from about 0.50% to about 5% molybdenum and from not less than about 0.40% to about 0.75% nitrogen, the balance consisting of substantially of Fe, and unavoidable impurities. Tungsten, from about 0.5% to about 5%, may also be added to enhance the strength of the alloy.

Abstract: A method and apparatus for parts conveyance a part which is connected to a conveyance device, such as a conveyer chain, through the use of a hanger tab. After the part is removed from the conveyance device, the hanger tab is detached from the part and discarded.

Abstract: A system for extracting oil from aqueous solutions or for extracting aqueous solutions from oil. The system imparts magnetic properties to the medium being extracted, using a multi-layer surfactant magnetic colloid. The system uses magnetic traps designed to efficiently extract the magnetic medium and remove it to a storage area.

Abstract: A switching power supply system which is able to connect two or more different power sources with different voltage levels, and can provide uninterrupted power even when the primary power source is low or absent. The output voltage is much more steady than that in a conventional switching power supply and the efficiency loss is smaller as well. As a result, the backup supply time is longer than a conventional UPS system. Finally, when used in, for example, a notebook computer, there is no need to use an AC to DC adaptor when connecting to commercial AC power since the switching power supply can be directly connected to the commercial AC power for operation.

Abstract: A heating unit assembly for vaporizers having a cover member, a heating unit housing, a heating unit holder and a locking mechanism which prevents the removal of both the cover member and the heating element while the vaporizer is operational. Preferably, the locking mechanism is the combination of at least one flexible locking finger and a post member and is provided with a key member. The key member is the prong of an electrical power cord plug which is inserted into the cover. The heating unit assembly also provides a connecting member which locks the cover member to the heating unit housing.

Abstract: An electric grill which vaporizes grease and juices and sears the food being cooked. The grill has two sets of heating elements, one located directly beneath the cooking surface and the second located proximate a smoker box. The grease and juices fall from the food located on the cooking surface onto the bottom of the grill which channels the grease and juices into the smoker box. The bottom of the grill also functions as a reflector plate to redirect heat towards the cooking surface. The grease, juices, and, optionally, wood chips may vaporized and smoked by the heating element located proximate the smoker box. A printed circuit board regulates the current passing through the heating elements.

Abstract: A gas burner, specifically a gas burner for cooking grills. The burner comprises and elongated conduit member having an upper portion of a generally inverted V-shape, a lower portion defining burner ports angled such that the flame caused by burning gases escaping from the burner port does not impinge upon the lower portion. The cross-section of the elongated conduit member burner provides an increased volumetric flow rate which does not require gas pressure equalization means to provide uniform heat generation across the length of the burner.

Abstract: A phosphorescent assembly for humidifiers and vaporizers that enables the vaporizers and humidifiers to be easily seen in dark or dimly lit areas. The presently preferred embodiment of the invention provides for the water reservoir in both the humidifiers and the vaporizers to be blow-molded from a phosphorescent, plastic material that will be luminescent for several hours after being exposed to radiation within the light frequency spectrum.

Abstract: A device for training an animal having a first collar, a second collar, spacer members, a mechanism for simultaneously changing the perimeter of at least one of the first and second collars, and a mechanism for limiting the changing of at least one of the perimeters of the first and second collars to a maximum perimeter and a minimum perimeter such that when either or both of the collars are increased to their respective maximum perimeter the animal is prevented from getting free from the training device and when the collars are reduced to their respective minimum perimeter the animal will not be harmed.

Abstract: This invention relates to repairing the water leakage problem of panel joints in an exterior building surface. In addition, this method may also be used to project new panel joints. A long lasting effective repair method is provided by using two extruded component parts assembled in the field to cover up the existing panel joints such that a number of P.E. Cavities and air links are created to form P.E. Seals around the existing panel joints such that elements such as exterior water can no longer reach the leaking joints. Since P.E. Seals can tolerate a significant degree of imperfection without causing the water infiltration problem, the effectiveness of the repair work can be expected to last for a long time.

Abstract: A ventless, combustible waste reduction process and apparatus which can utilize any type of combustion means for disposing of hazardous, as well as non-hazardous, burnable waste. Such wastes include toxic combustible liquids, oil slurries, soils contaminated with dioxin, PCBs, creosote, or any other potentially harmful or toxic combustible material. In particular, the present invention relates to a ventless, combustible waste reduction process in which the operating pressure is slightly below atmospheric pressure and which employs no venting or stack discharge of pollutants whatsoever. The entire flue gas stream is scrubbed, enriched with oxygen and recycled to the combustion chamber in varying amounts in response to pressure and temperature measurements taken in the combustion chamber to maintain the pressure and temperature in the combustion chamber within pre-selected ranges.
