Abstract: An apparatus for creating pressure pulses in the fluid of a bore hole is described. The preferred embodiment takes the form of a mud pulser apparatus having a signalling valve controlled by a variable pilot valve. The forces on the signalling valve are balanced and controlled by the flow of mud through the variable orifice of the pilot valve. The arrangement is such as to act like a hydraulic amplifier, and results in the signalling valve being compensated for variable flow rates. In the preferred embodiment, the pilot valve has rotary vanes that allow it to be self-cleaning.

Abstract: A modulator is disclosed for creating a pressure pulse in a fluid-filled well. The modulator comprises a tool body on which a plurality of extendable arms are mounted. The arms may be retracted into a stowed position substantially adjacent the tool body, or may be extended to meet the wall of the borehole. The arms are preferably resilient bowsprings that may be flexed outwards from the tool by means of an actuator pushing on at least one end of the springs. A flexible valve sleeve or bag is suspended between the arms and cooperates with a valve mounted adjacent the sleeve on the tool body. The valve sleeve creates a fluid-flow path through the valve, and in operation, the valve closes one end of the valve sleeve to create the pressure pulse. Sealing of the valve sleeve against the wall of the well is a result of the fluid pressure inflating the sleeve against the well wall. As a result, sealing takes place over an extended area of the bag and is dynamically responsive to changes in fluid flow or pressure.

Abstract: An apparatus for creating pressure pulses in the fluid of a bore hole is described. The preferred embodiment takes the form of a mud pulser apparatus (10) having a signalling valve controlled by a variable pilot valve (34). The forces on the signalling valve are balanced and controlled by the flow of mud through the variable orifice of the pilot valve. The arrangement is such as to act like a hydraulic amplifier, and results in the signalling valve being compensated for variable flow rates. In the preferred embodiment, the pilot valve has rotary vanes that allow it to be self-cleaning.

Abstract: A method and system are provided for executing a transaction relating to a first futures contract. The first futures contract involves a tradable asset, such as crude oil or another commodity, and a first contract price and a first settlement price expressed in a first currency, such as U.S. dollars. The first settlement price is updated on a periodic basis, typically daily. The method involves providing a second futures contract having an underlying instrument that includes the first futures contract. The second futures contract includes a second latest possible delivery date and a second contract price and a second settlement price that are denominated in a second currency. The second settlement price is updated periodically. A periodic mark-to-market operation credits or debits a buyer of the second futures contract based on the periodic update to the second settlement price.

Abstract: A method and system for supplying agricultural pesticide information and advice combines information regarding a particular pest, and the plant or crop which a user desires to protect from that pest, and generates information regarding which pesticides are suitable for that purpose.

Abstract: The invention relates generally to framing systems and more particularly is concerned with systems adapted to mount panels or laminates in an array on a supporting roof structure of a building exemplified with the mounting of solar electric photovoltaic (PV) panels. The framing system described uses extruded elongate elements with a sealing element to frame the PV panel as a weatherproof PV solar roof tile. Individual frame element profiles effectively embody the PV building integration, (BiPV) or mounting method, of the solar tile within the frame itself. Only a few additional flashing components are needed to complete the PV tile array as part of the roof, or with minor variations, as a PV wall cladding. Full BiPV panel mounting methods show potential to be used for co-generation (PV/T) of solar thermal energy capture in buildings.

Abstract: A can opener has a first and a second handle member pivotably connected to be moveable between an open disposition and a closed disposition. They can be squeezed together in one hand of the operator to rotate a drive wheel. A cutting wheel is mounted onto the first handle member. A radially facing aperture is formed through a part of said first handle member so that the drive wheel may partly protrude to engage the rim of the can and press it against the cutting wheel. The drive wheel is mounted rotatably onto a rivet which is held slideably in a slot in the main plate of the first handle member to be moveable towards and away from the cutting wheel.
