Show moreMethods and apparatus for treating waste with radio frequency include a wall defining a radio frequency treatment chamber through which waste may be passed. A source of radio frequency energy energizes the radio frequency treatment chamber to heat the waste and drive off vapors therefrom leaving solid residue to be disposed of. A guard heater and/or insulation maintains the wall at substantially the same temperature as the waste being heated by the radio frequency to prevent vapors from condensing on the waste.

Show moreA method and apparatus are provided for distinguishing microscopic size, elongated fiber-like particles from cubically shaped, irregularly shaped, or spherically shaped particles in a mixture suspended in an electrically conducting liquid medium and for counting the fiber-like particles. In accordance with the method, an electrical zone sensing apparatus is provided with a screen means having microscopic openings therein of predetermined size to filter from the suspension particles having an effective area larger than the size of screen openings. Particles passing through the screen and through the sensing aperture of the zone sensing apparatus are separately sized by volume characteristics of electrical signals generated. The electrical signals having predetermined volume characteristics associated with the maximum spherical particles for passing through the screen openings are counted as non-fiber particles; whereas signals having larger volume characteristics are separately counted and designated as fibers. By the use of screens of successively smaller sizes, the larger particles including fibers having larger transverse cross sections may be successively filtered from the suspension and from reaching the sensing aperture. Therefore, smaller fibers having smaller cross-sectional area may be distinguished from particles having diameters approximating that of the smaller screen size openings.

Show moreAn apparatus for generating odor including a disk having a substrate with a dispersing material retaining at least one releasable aroma positioned with respect to the substrate. The dispersing material includes a structure, such as a plurality of openable pores, that is physically responsive to a stimulus such as heat or light. A device provides the stimulus to the dispersing material upon demand as a function of a signal, wherein the plurality of pores within the dispersing material are reversibly enlarged as a result of the stimulus.

Show moreThe present invention is directed to a process for the conversion of waste plastics and scrap rubber to a high quality synthetic crude oil which can be separated by fractionation into gasoline, diesel fuel and gas oils suitable as a feedstock to a catalytic cracker. The process generally includes the steps of heating the plastic scrap and scrap automotive tires in a hydrogen atmosphere at moderate temperatures and pressures. It has also been determined that the polymeric waste material must be present in combination with the scrap automotive tires to attain conversion of the scrap automotive tires to liquid hydrocarbon.

Show moreMethods for the crystallization of nano-size crystals of molecular organic compounds while operating at a low supersaturation. The methods are based on controlling the domain size available during the crystallization process. In one exemplary method, microcontacted printed self-assembled monolayers (SAMs) with local domain area sizes ranging up to 2500 .mu.m.sup.2 and fabricated SAMs generated from electron beam lithography, are employed to control the size, orientation, phase, and morphology of the crystal. In another exemplary method, a continuous micro-crystallizer having a vessel diameter of 25 microns or less is used to ensure that that the maximum size of the crystals in at least one dimension, ad preferably two dimensions is constrained by the vessel itself. The methods allow control of supersaturation and growth conditions, as well as manageability over crystallinity and polymorphism, and each method's domain size has the potential for further reduction.

Show moreThis invention relates to a method and device for continuously removing and concentrating specific molecules or substances from a gas stream and depositing such molecules or substances in a liquid film stream in a controlled and quantitative fashion. The device includes a hollow tetrafluoroethylene tube or a hollow tube having an inner surface coating of tetrafluoroethylene. The inner surface of the tube is etched by means of a chemical etching agent. An inlet/injector is attached to the outer circumference or inlet, circumferential face of the tube. The inlet/injector has liquid dispersion ports uniformly distributed around the circumference of the processor tube whereby a surfactant containing liquid may be uniformly dispersed from the inlet/injector onto the inner wall of the processor tube where it may flow, in a thin film manner, from the inlet of the tube to the outlet of the tube. The inlet/injector also has a gas injection port whereby a gas containing the molecules or substances sought to be removed and concentrated can simultaneously be injected into the top hollow portion of the tube. An outlet cap is attached to the outer circumference or outlet circumferential face of the tube. The outlet cap has a liquid collection well with a port or other means whereby the liquid flowing down the inner wall of the tube can be collected and transported to an analyzer. The outlet cap also has a gas port whereby the sample gas undergoing analysis can be removed from the tube and vented, treated or otherwise disposed of.

Title: Technique for Establishing a Virtual Backbone in an Ad Hoc Wireless Network
Creator: Alzoubi, Khaled Muhyeddin M., Wan, Peng-jun, Frieder, Ophir

Show moreAn algorithm on a computer readable medium for efficiently creating a message efficient virtual backbone in a wireless ad hoc network utilizes three phases to establish an efficient network among the independent transceivers of a wireless ad hoc network. Independent transceivers within the transmission range of each other are neighbors. A leader election and tree construction phase constructs a tree of neighboring transceivers with one transceiver being designated the root and with each transceiver establishing and recording its location in the tree structure and the identifiers of its neighbors; and reporting when the tree is established. A level calculation phase determines the level of each transceiver away from the root transceiver, with each transceiver recording the level of its neighbors. Precedence for each transceiver is established with consideration of each transceiver's tree level and identifier, with tree level being paramount in deciding precedence; and reporting when the levels of the tree are established. A backbone construction phase establishes all transceivers as a dominator or a dominatee, with the dominators forming the network backbone and the dominatees all being neighbors to a dominator. Within the network each transceiver only needs to know the information of its neighboring transceivers.

Show moreA waveguide structure is emplanted in the earth to bound a particular volume of an earth formation with a waveguide structure formed of respective rows of discrete elongated electrodes wherein the spacing between rows is greater than the distance between electrodes in a respective row and in the case of vertical electrodes substantially less than the thickness of the hydrocarbonaceous earth formation. Electrical power at no more than a relatively low frequency is applied between respective rows of the electrodes to deliver power to the formation while producing relatively uniform heating thereof and limiting the relative loss of heat to adjacent barren regions to less than a tolerable amount. At the same time the temperature of the electrodes is controlled near the vaporization point of water thereat to maintain an electrically conductive path between the electrodes and the formation.

Show moreThe present invention can enable increasing refinement of role-based permission to access data within a Role Based Access Control (RBAC) controlled computer system by enabling constraints to be written on the role-based permissions. The constraints may utilize each and every type or combination of subject, object, or environment information extracted from sources internal or external to the controlled computer system and may evaluate the content or context of the information extracted to enable refined and dynamic access after the role permission assignment and immediately before every access grant without the reassignment of roles.
