Title: Tire tube
Inventor: MACKELVIE WINSTON R
IPC: B29B17/00
Filed: 1998-01-05
Granted: 2003-03-18
Abstract: A novel container called a tire tube is made from whole, used tires. They are first turned inside out or inverted. Several tire tubes may be connected together side by side with holes aligned using fasteners such as self-tapping screws. With the ends sealed the tire tube may be used as a container for toxic substance storage, or, filled with sand to act as a highway bumper. With the ends left open the tire tube may be used as a conduit, or a culvert. The open-ended tire tube may be supported on wheels to allow rotation at a slight angle to the horizontal.  With the higher end being fed material, the rotating tire tube tumbles the material to the exit end. With rock added, the result of tumbling is a pulverizing action.  By adding organic material and keeping it moist the rotating tire tube becomes a continuous-action composter.

Title: Power management system for downhole control system in a well and method of using same
Inventor: TUBEL PAULO S
IPC: E21B47/00
Filed: 1998-01-14
Granted: 2004-09-14
Abstract: A downhole power management technique for a downhole well control system maximizes the number of downhole devices which require electrical power. In accordance with this technique, downhole devices which require power and are addressable will be at a low power consumption state (e.g., sleep or dormant mode). When requested by a downhole or surface controller, the downhole device will turn itself on to an active mode and perform its intended function or task (such as transmitting data, acquiring data, actuating a tool or the like). Preferably, only one downhole device is in its active mode at any one time. As a result of this power management technique, the power requirement downhole will be relatively low and substantially constant regardless of the number of downhole devices requiring power.

Filed: 1996-08-23
Granted: 2006-11-14
Abstract: A system and method non-invasive biomedical optical imaging and spectroscopy with low-level light is described. The technique consists of a modulated light source (120) coupled to tissue (100) of a patient to introduce excitation light. Fluorescent light emitted in response to the excitation light is detected with sensor (148). The AC intensity and phase of the excitation and detected fluorescent light is provided to a processor (160) operatively coupled to sensor (148). Processor (160) employs the measured re-emission kinetics of excitation and fluorescent light to "map" the spatial variation of one or more fluorescence characteristics of the tissue (100). The fluorescence characteristic may be provided by exogenous contract agents, endogenous fluorophores, or both. The variations is determined by solving frequency domain diffusion equations at a number of designated points in the tissue as part of a recursive estimation algorithm. Processor (160) generates an imaging signal in accordance with the spatial variation of the fluorescence characteristic for provision to an output device (164). The output device (164) displays an image corresponding spatial variation of the fluorescence characteristic which corresponds to tissue (100) to aid in the detection and diagnosis of disease.

Abstract: An improved trap for catching insects that combines the use of attractant light and a sticky surface to trap the insects is provided. The trap includes a base, a dark colored insect trapping insert, a screen, a light source, and a cover housing. The insect trapping insert is secured to the base and has a sticky substance deposited on its exposed surfaces. The screen is arranged above the insect trapping insert in the insect trap in order to conceal at least a portion of the insect trapping insert. This serves to limit the extent which trapped insects. are visible to individuals who pass by the insect trap. The light source, which typically comprises an ultraviolet light emitting fluorescent tube, is positioned above the screen and serves to attract insects. The base, insect trapping insert, screen and light source are covered with the cover housing. The cover housing is formed from a clear, translucent or opaque plastic and has a roughened inside surface which serves to increase the output of ultraviolet light from the insect trap.

Abstract: An apparatus for determining radial distribution of resistivity of earth formations surrounding a wellbore. The apparatus includes a sonde mandrel having an insulating exterior surface and electrodes disposed on the insulating surface at spaced apart locations. The electrodes are connected to circuits for measuring a focused current resistivity within a predetermined longitudinal span. The electrodes are also connected to circuits for measuring electrical impedance between pairs of electrodes spaced apart at a plurality of different longitudinal spacings. The preferred embodiment includes a voltage measuring circuit interconnected between a pair of electrodes which is positioned between a closest spaced pair of electrodes connected to the impedance measuring circuits, so that a vertical resolution of the impedance measurements can be limited to approximately the axial spacing of the pair of electrodes connected to the voltage measuring circuit. A method according to the invention for determining the distribution of resistivity of earth formations surrounding a wellbore includes the steps of measuring a focused current resistivity of the earth formations to determine a composite resistivity of an uninvaded zone, an invaded zone and a flushed zone. Impedance is measured between pairs of electrodes, each pair having a different longitudinal spacing, and resistivity of the flushed zone and the invaded zone are determined from the measurements of impedance. The resistivity of the uninvaded zone can then be determined from the measurement of focused current resistivity.

Abstract: A drop former includes a rotary screen forming an internal chamber into which a flowable chemical is introduced, the chamber being kept at atmospheric pressure.     The screen has a thickness in the range of .1 to 1.2 mm.  As the screen moves, the flowable chemical is caused to impinge against a pressure member disposed within the chamber to create a hydrodynamic force which forces the chemical through openings of the screen, thereby forming drops which are transferred onto a transfer surface. The drops harden into particles on the transfer surface and are subsequently removed therefrom and collected. The screen may be formed of a photochemically etched, or laser-drilled, metallic sheet.

Abstract: An improved control system, particularly useful for Subsurface Safety Valves (SSVs) is disclosed. The control system has an operating piston which acts on a flow tube to move a flapper to an open position. The flapper is spring-loaded to close when the flow tube moves up. A return spring acts on the piston to lift the flow tube to allow the flapper to close. The operating piston is exposed to a control line from the surface as well as to a bypass piston.   Opposing the hydrostatic forces of the control line is a pressurized chamber with a pressure in excess of the hydrostatic pressure. A secondary chamber acts on one side of the equalizing piston and is pressurized to a pressure less than the anticipated hydrostatic pressure in the control line. The system, including the operating piston, is configured so that when leakage occurs into or out of the control system in many places, the SSV will fail toward its failsafe closed position.
