Abstract:
Methods and systems for establishing Taylor-Couette flow in a fluid are provide. Aspects of the disclosed methods and systems incorporate Taylor-Couette flow in combination with a source of radiation to provide more uniform radiation exposure to the fluid and its components. Common problems of non-uniform radiation levels and concentration boundary layer effects in UV reactors are largely eliminated using the methods and devices provided herein.
Abstract:
The aim of the invention is to continuously separate inhomogeneous remaining material (IR) generated by a pyrolysis installation such that the remaining material is sorted as completely as possible. To this end, specially selected components are combined with one another in an advantageous arrangement. An essential element of the installation is the separation of coarse remaining material (GR) in a coarse sieve (2) and the subsequent separation of the residual remaining material (R) in a zigzag separator (6) into a light remaining material (LR) and into a heavy remaining material (SR). Using the installation, the portions containing carbon are, in particular, separated from the remaining material (R). The individual components are constructed such that they are, for the most part, self-cleaning in order to enable an operation which is free of interruptions.
Abstract:
A system for separating constituents from a base material (20) using RF energy which is coupled to a reaction chamber (18) by way of a windowless transmission line (12). By eliminating the need for a window, traditional limitations placed on the maximum power delivered to the resonating cavity (34) are eliminated. Thus, the only practical limitation on the RF energy which can be delivered to the resonating cavity (34) the ability of the RF energy source (10) to produce that energy and the ability of the resonating cavity (34) to manage that energy.
Abstract:
Dispensers and refills for volatile liquids, such as fragrances, are disclosed. Dispensers and refills (20) in combination with dispensers according to the present invention may comprise a volatile liquid and a housing (30). In certain embodiments, the volatile liquid of the present invention has a predetermined evaporation rate, measured and calculated by the method described herein. In other embodiments, the volatile liquid exhibits a predefined relative evaporation rate. In addition to the housing, the present invention includes optional components, such as a motorized (32) fan and/or a wick (31), to facilitate release of the volatile liquid into the atmosphere.
Abstract:
The invention relates to haloalkane dehalogenases and to polynucleotides encoding the haloalkane dehalogenases. In addition methods of designing new dehalogenases and method of use thereof are also provided. The dehalogenases have increased activity and stability at increased pH and temperature.
Abstract:
An apparatus and method for rendering infectious and medical waste safe through heating and the disposal of said waste includes a body portion with a chamber to receive a container of medical waste. The chamber is connected with a filter for biological materials which escape from the waste container during heating. The contaminants are directed toward the filter by flowing out gas from the container in a predetermined direction as the waste container is heated to a temperature of preferably not less than 350 DEG F and preferably not more than 385 DEG F to render the waste biologically safe and unreusable.
Abstract:
A new set of effective, environmentally safe, nonflammable, low-toxicity refrigerants, solvents, foam blowing agents, propellants, and firefighting agents is disclosed. The agents are clean, electrically nonconductive, and have short atmospheric lifetimes, zero ozone-depletion potential, and low global warming potentials. The agents comprise at least one fluoroiodocarbon agent satisfying the general formula: CaHbBrcCldFeIfNgOh, wherein a is between and including 1 and 8; b is between and including 0 and 2; c, d, g and h are each between and including 0 and 1; e is between and including 1 and 18; and f is between and including 1 and 2, either neat or mixed with additives selected from the group consisting of: alcohols, esters, ethers, fluoroethers, hydrocarbons, hydrofluorocarbons, and perfluorocarbons.
Abstract:
Described is an air and surface purifying device having a purifying cell structured for maximizing the realized photocatalytic reaction at a photocatalytic surface without using an additional ultraviolet bulb. The purifying cell positions at least three photocatalytic surfaces about a single ultraviolet bulb such that the photocatalytic surfaces substantially encompass the ultraviolet bulb and are saturated by ultraviolet light radiating from the ultraviolet bulb. Because the photocatalytic surfaces are saturated, the potential photocatalytic reaction at the photocatalytic surfaces is fully realized. Stated differently, the realized photocatalytic reaction is maximized. Because the purifying cell maximizes the realized photocatalytic reaction, the purifying cell maximizes the purifying capacity of the photocatalytic surface and, thus, the purifying cell itself.
Abstract:
A device for introducing active substances, such as aromatic substances, insecticides and the like, into ambient air, comprises a holder for a carrier with a wick impressed thereon, which carrier can be placed in the holder and is replaceable. A mechanism to be operated by hand is provided for operating an ignition element, which can be placed in the holder and is replaceable, as for instance a gas lighter, to enable a wick to be ignited when a carrier with this wick has been placed in the holder.
Abstract:
A method for containing potentially infectious devices. The potentially infectious devices are deposited in a container which contains a monomer, a reducing agent and water. An oxidizing agent is later added to cause polymerization of the monomer to immobilize the devices, and to act as a disinfecting agent due in large part to the exothermic nature of the reaction. In an alternate embodiment, the composition contains a monomer, a thickener and water. Before use, this solution is admixed with an oxidizing and reducing agent and the thickened solution is poured into a container having disposed therein potentially infectious devices. Related methods, kits, devices, and compositions are also disclosed.
