摘要:
The concentration of sulfur trioxides in an FCC unit regenerator is maintained within environmentally accepted limits, while maintaining an adequate amount of gas for fluidizing conditions in the regenerator, by admixing the regenerator oxygen-containing gas with an inert gas. The quantity of the inert gas is controlled by a control loop measuring the pressure drop in the regenerator, and adjusting the amount of the inert gas to maintain the pressure drop within the predetermined limits.
摘要:
Sulfur trioxide concentration in the flue gas of catalytic cracking regenerators is maintained at a predetermined level by controlling the flow rate of oxygen-containing regeneration gas into the regenerator, and, optionally, the amount of carbon monoxide combustion promoter in the regenerator.

There is disclosed stable aqueous slurry automatic dishwasher detergent compositions comprising a chlorine bleaching agent and a dual function bleach stabilizer and anticorrosion agent comprising sulfamic acid, or its water soluble salts. Such formulations containing a molar ratio of at least about 0.5:1 sulfamic acid/bleaching agent provides protection against corrosion of silver metal and stabilizes bleach in the detergent composition.

A cleansing composition includes a salt of chlorhexidine such as chlorhexidine digluconate and at least one nonionic surfactant which does not include any polyoxypropylene/polyoxyethylene block copolymers. Also included in the composition is at least one amphoteric surfactant. Other additives such as viscosifiers or thickeners, emollients, fragrances, perfumes, coloring agents, preservatives, foaming agents, fungicides and the like may also be added. Preferably, the composition does not include alcohol as a carrier. The cleansing composition has been found to exhibit improved antibacterial properties while remaining mild on the skin.

A fluid dispensing brush head includes bristles whose base portions engage apertures in a resilient member to create seal which is disrupted when the bristles are deflected as in use to selectively dispense a fluid. The bristles may be affixed to or form part of a unitary bristle carrier which, along with the resilient member, is removably secured to the body of the brush head so as to permit the brush head to be disassembled and thoroughly cleaned.

A skin cleansing composition suitable for removing ink and other stains from the hands and arms of a user includes an effective amount of a low molecular weight alcohol having from one to twelve carbon atoms and an effective amount of a peroxide releasing agent, e.g., a perborate salt, preferably sodium perborate, such that together, the alcohol and perborate salt provide a synergistic reaction that effectively removes ink from the skin of the user. Other additives such as fillers, abrasives, and detergents may be employed to provide further cleansing action.

A valve and dispensing assembly for dispensing powdered material from a container includes a flexible tube intended to be collapsed to actuate a valve which permits the tube to selectively open for dispensing the material through the tube. The assembly includes a flexible tube apparatus including a body attachable to the container and a valve releasably received within the tube and normally closing it off. Collapse of the tube causes it to move relatively of the valve to unseat it and open the tube for material discharge. The assembly also includes a declumper secured to the tube for movement therewith during collapse of the tube. The valve closes off the tube when in its uncollapsed condition while the tube and declumper move relatively of the valve during collapse to open the tube. A portion of the declumper is bifurcated and has serrated opposed edges which can engage the head of the valve during the tube collapse to assist in breaking up clumps which may have formed in the material.

An originally viscous, non-flowable and non-pumpable cleaning composition made less viscous, flowable and pumpable by the addition of psyllium husks to the composition. The cleaning composition includes an oil phase including at least one of a hydrocarbon oil and a hydrocarbon solvent and mixtures thereof, and at least one of a fatty acid and a non-fatty acid soap surfactant; and the water phase including water and a base. The addition of psyllium husks in various amounts relative to the amount of water in the composition makes the composition flowable. In particular, the addition of from about 2 to about 38 percent by weight of psyllium husks has been found to be suitable to provide a flowable composition containing between about 30 and 55 percent water. A method for the preparation of flowable cleaning compositions is also provided. The cleaning composition (13) forms a novel combination with a container (10) as a replacement element for dispensing apparatus.
摘要:
A new heat sink composition having relatively high volumetric heat capacity and relatively high density have been prepared. The compositions comprise a set of formulas including: a) 50-95% oxide of iron and 50-5% of a mixture of clay, an organic binder or an inorganic binder, where said mixture can contain any portion of clay, organic binder or inorganic binder in any proportions provided the mixture adheres to the 50-5% compositional range; b) 15-95% oxide of iron and 85-5% of clay; c) 15-85% oxide of iron, 10-2% of a transition metal oxide other than iron and 75-13% inorganic binder; and d) 50-80% oxide of iron, 15-5% of talc and 35-15% clay. The compositions show good dried and fired properties and can even be loaded and fired in-situ because they possess good dried crush strength.
