Abstract: A combustion burner resulting in low oxides of nitrogen includes a primary combustion zone, for use as an ignition source. The primary combustion zone locating within a combustion chamber, and being separated from the base of the combustion chamber by a wall. A burner provides a secondary oxidant stream that is delivered to the combustion chamber at the base of an exterior wall, to entrain and mix with flue gases present in the combustion chamber. Then secondary fuel is injected into the resulting secondary oxidant-flue gas mixture. Combustion of the secondary fuel with the oxidant flue gas mixture results in lower concentration of oxides of nitrogen emitted to the atmosphere.

Abstract: A fragrance sample is provided which is made from two plies (a bottom ply and a top ply) of material. A cosmetic (such as a wet fragrance) sample is deposited on the bottom ply. A wall is formed in at least one of the plies and is sized and shaped to surround the sample. The two plies are then adhered together to form a liquid tight seal between the two plies. The bottom ply can be provided with a flow barrier to impede the flow of the sample-on the bottom ply.

Abstract: The biodegradable badge has a paper name tag placed within a translucent envelope carried by a lanyard secured to the envelope by at least one clamp. The paper name tag degrades readily. The translucent envelope shows the name tag but upon disposing of the envelope, it degrades in the waste stream and at a landfill. The envelope has a material that degrades rapidly by solar, thermal, and chemical action with minimal release of toxic and volatile organic compounds. The lanyard also degrades readily in the waste stream with material such as textile blends or that of the envelope. The clamp joins the lanyard to the envelope. Designed for single use, the clamp strongly grips the lanyard and then the envelope, and then the clamp degrades when placed in the waste stream. The entire biodegradable badge poses no long-term pollution of the environment as it uses formulations, such as polyethylene terephthalate (g) and poly lactic acid, along with natural fibers such as cotton and wool.

Abstract: A mounting assembly uses one hinge and one cam bolt mutually offset upon a two piece collar. A hopper tee has a member usually a vertical pipe and occasionally a horizontal pipe that connects to a hopper flange to receive bulk material. This assembly has two collars that mutually engage and surround a hopper flange. Pins pass through the collar pieces and the hopper flange then secure to tapped holes in the collar pieces to prevent rotation. A collar piece mounts a hook bolt and the other collar piece mounts a hinge in a spaced apart and offset manner. The other collar piece has a pivotal connection to a hinge arm and opposite the hinge arm, the hook bolt engages a cam. Opening the cam unfolds the tee downwardly while the hook bolt remains engaged. This partially open position allows for removal and installation of a valve. In opening and closing the assembly, the hinge arm spaces the flange below a hopper to admit a valve.

Abstract: The invention relates to a variable air volume control apparatus which compensates an open area ratio to be in direct proportion to an opening ratio at a low opening ratio range according to an open angle of a damper blade to achieve accurate and precise air volume control. The variable air volume control apparatus includes a damper blade disposed rotatably within the duct for opening or closing an air flow path and an actuator for rotating the damper blade. The apparatus also includes an air flow path expansion mechanism having a curved surface for expanding the air flow path in accordance with an open angle of the damper blade. The invention allows obtaining the open area ratio in direct proportion to the opening ratio at the low opening ratio range through simple structural improvements, thereby improving linear characteristics of an air volume change ratio with respect to the opening ratio to more accurately and precisely control the air volume.

Abstract: An airpot or dispenser liquid level float, provided for vertically shifting upon the air tubes of an airpot or other dispenser, the float incorporate a pivotally mounted indicator, for viewing through a view window of the dispenser, for furnishing and indication as to the level and amount of liquid remaining within the dispenser, during its usage and application.

Abstract: A bucket bale spear bolts together upon a frame, that slips upon the cutting edge of a bucket, and then one bolt secures the frame to the bucket. The frame receives a spear and two balance spikes upon a bracket. A centered tube accepts the spear and secures it with a transverse bolt. The tube provides additional bending resistance for the spear at less weight than a proportional length of spear. The balance spikes also bolt to the frame. The frame, spear, and balance spikes can be shipped and merchandised compactly. At the farm or the ranch, the bucket bale spear assembles readily with hand tools.

Abstract: Modifications of a scroll compressor provide a bellows suitable for liquid cooling and a plunger actuated seal for the scroll tips of various equipment. A bellows spans the fixed and the orbiting scrolls and hermetically seals the scroll device. Using two bellows, the present invention allows for liquid cooling of a compressor with an inlet and an outlet to exhaust heated coolant to a heat exchanger. Then the scrolls have a spiral upon a plate that ends in a tip. A seal upon the tip that abuts the fixed scroll upon a biased plunger modifies existing scroll designs to maintain the seal in contact with the fixed scroll. The modifications also provide an improved coating that seals the fixed and orbiting scrolls to each other without the use of epoxy, disassembly, and cleaning.

Abstract: A rotary tumbler metal reclaimer includes an inner cylinder and a concentric outer cylinder that rotate simultaneously. The inner cylinder includes a first compartment that intakes material for breaking by teeth, a second compartment that receives broken material from the first compartment and crushes the material into smaller particles, and a third compartment wherein particulate material enters the space between the inner cylinder and the outer cylinder by attrition through perforated screens. The second compartment includes a crusher having various features for crushing lump material as it rotates. The third compartment provides further breakage and conveyance of particulate material. Particulate material then returns proximate the intake for screening into fine and coarse sizes and then collecting for reuse. Metallics and metallic oxides exit the tumbler through apertures in the rear of the third compartment for collection.

Abstract: The present disclosure provides a device sized for insertion into an inner tube of a roll of paper towels or toilet paper comprising a insert card absorb a fragrance and which is bendable, the insert allowing fragrance to emit by evaporation from the insert into the air and an outer packaging for containing the insert card, the packaging being a substantially impervious moisture and odor barrier.

Abstract: A nursing bottle formed of a large volume container, incorporating a vent tube that extends to vent pressure at all times. The nursing bottle may have a cylindrical shape or other configuration that prevents formula placed therein from blocking the vent tube regardless of its angular disposition. The vent tube extends distally from the vent insert, operatively associated with a collar, that holds the vent structures and the nipple to the wide rimmed opening. In addition, the vent tube has a conical shape of decreasing diameter distally toward the center of the bottom to dissipate the pressure that may cause leakage from the bottle. Further, the vent insert has a major and minor seal that prevents leaks out of the collar and onto an infant.
