摘要:
An apparatus for collecting a substance has a fluid source providing pressurized fluid, a heating device, a heat transferring device and a vacuum producing device. The heating device is coupled to the fluid source and is adapted to cause a first pressurized fluid from the fluid source to become heated. The heat transferring device is coupled to the heating device for receiving the heated first pressurized fluid, and is adapted for transferring heat from the first pressurized fluid to a heatable substance. The vacuum producing device has first and second inlet openings, the first inlet opening is fluidly coupled to the fluid source for receiving a second pressurized fluid from the fluid source and the second inlet opening is adapted for receiving the heatable substance.
摘要:
The present invention relates to a biodegradable plastic made from a combination of at least one synthetic plastic polymer, at least one natural polymer and a natural polymer attacking agent and articles made therefrom.The present invention further relates to a method of eliminating hydrocarbon contaminating a region subjected to extreme temperatures by contacting the region with hydrocarbon-degrading microorganisms and adjusting the temperature of the region for optimum growth.The present invention also relates to a method of treating aspirin-treatable conditions comprising administering to a patient in need of such treatment a compound of Formula I ##STR1## In addition, the present invention relates to a method of protecting a philatelic item bearing a mark identifying an expert or owner of the item and possibly an additional distinguishable mark specific to the philatelic item from alteration.

摘要:
Disclosed is an improved high sorbency nonwoven fabric and its use particularly as an oilsorb material. The high sorbency nonwoven is preferably made by multi-bank meltblowing and different perturbing thermoplastic fibers of, for example, propylene polymers in separate banks to provide a fiber density gradient through the thickness of the fabric. The sorbent nonwovens have high bulk and strength, oil capacity and oil absorption rates making them particularly suited to such applications. Treatments and additives for such materials are also disclosed.

The present invention relates to compositions containing bacteria capable of degrading hydrocarbons, such as petroleum or petroleum products and methods for their use.
摘要:
A particulate material, as well as a method of manufacturing and using the material, for promoting growth of petroleum degrading bacteria to aid in bioremediation of oil spills on water and in wetlands which consists of a core of microbial available nutrients having a coating, comprised of oleic acid and either stearic acid, palmitic acid, or a mixture thereof, which is lipophilic, and biodegradable, for retaining the nutrient in the oil for gradual release to microorganisms between applications of the material.
摘要:
An apparatus for collecting floatable liquids such as oil and gasoline, in particular in the case of oil-contaminated or gasoline-contaminated water surfaces. The apparatus includes a collecting container which is vat-like or cylindrical and which is immersed into the water surface; an annular float on which the collecting container is at least partly borne in its upper region; an inlet opening for the liquid which is to be collected and arranged directly beneath the float; at least one delivery pump for transporting the liquid in the collecting container to a disposal station, the float having a buoyancy arrangement such that the float substantially rests on the water surface; a funnel-like intake trough which encloses the collecting container and is located beneath the float, the trough forming, along with the float, a defined intake gap which corresponds to the width of the liquid stream which is to be taken in, the intake gap between the underside of the float and the upper side of the intake trough being variable in its width and being less than or equal to 300 mm.
摘要:
A system for removing oil from oil/water or oil/sand or oil/water/sand mixtures. An oil/water mixture is taken from an oil spill on the surface of the water or from other sources such as producing oil wells and is transported to a surge tank where it is agitated and then passed on to a separator which separates the oil from the water. The system also covers separating oil from sand or earth when the spill is on land.
摘要:
An improved process for absorbing oils and especially separating and recovering oils from an aqueous medium or aqueous/wetted medium using an absorbent oleophilic biodegradable sponge material comprised of essentially fat-free, foamable natural products, specifically animal proteins or plant polysaccharides, such as gelatin, collagen, egg white albumen, gum agar, gum arabic, gum karaya, and locust bean gum, which absorb oils at a rate of at least about 30 times their weight.
摘要:
Method of decontamination of a hydrocarbon-polluted environment by the use of bacterial compositions. The method is a process of biological decomposition of the hydrocarbons using, as decontaminating active ingredients, bacterial compositions composed of one or more strains from among the following microorganisms: Azotobacter vinelandii 21, Pseudomonas sp.9, Pseudomonas sp.19, Pseudomonas sp.31 and Acinetobacter calcoaceticus 23. In the method, prior analysis of the chemical composition of the pollutants is essential in order to select, in accordance with this composition, the mixture of strains of the most active microorganisms from among the five mentioned above, taking into account the natural conditions of the polluted environment. The bacterial composition also contains inorganic salts supplying N and P, and additives needed for bacterial growth.The method is used to decontaminate hydrocarbon-polluted soils, fresh water, salt water, waters from technological processes and industrial waste waters or effluents.
