Title: Em-guided drilling relative to an existing borehole
Inventor: BITTAR MICHAEL S
IPC: E21B47/022
Filed: 2008-01-18
Abstract: Parallel drilling systems and methods suitable for drilling wells for steam-assisted gravity drainage (SAGD). In some method embodiments, a tilted-antenna tool gathers azimuthally- sensitive electromagnetic signal measurements. Such measurements enable accurate measurement of inter-well distance and direction, thereby providing the necessary information for drilling accurately-spaced wells having reduced vulnerability to 'short-circuits' that inhibit effective reservoir exploitation. In some other method embodiments, a tilted-antenna tool transmits azimuthally non-uniform signals as it rotates. The attenuation and azimuthal variation detected by one or more receivers enables accurate direction and distance determination. The transmitter and receiver antennas can in some cases be combined into a single tool, while in other cases the transmitters and receivers are placed in separate wells to increase detection range.

Title: Dynamically tuned wave energy converter
Inventor: GREGORY BRUCE
IPC: F03B13/20
Filed: 2009-09-19
Abstract: A wave energy converter comprises a vessel 3 exposed to wave action, and an inertial reaction mass 65 which may use a pendulum (figures 10, 14, 17), gyroscope or a curved track 63. A pendulum may be tuned by moving the mass along the pendulum arm, and a mass 65 on a curved track 63 may be tuned by changing the curvature of the track 63. The vessel is dynamically tuned to resonate with the ocean swells, e.g. by moving ballast vertically or horizontally within the vessel (figures 4-6), or by adjusting the depth of the vessel in the water. The hull may be shaped such that this varies the submerged length and/or the added mass provided by the water. The vessel may have fins to increase pitching and a vertical plate damping keel to suppress roll and yaw.

Title: Method of manufacturing a mechanically lined pipe
Inventor: BERTASO DANIEL
IPC: F16L58/08
Filed: 2009-12-22
Abstract: A method of manufacturing a mechanically lined pipe (MLP) having an outer pipe and an inner liner comprising at least the steps of: forming the outer pipe as a single length; forming an inner liner former being wholly or substantially the same length as the outer pipe of step (a); locating the inner liner former of step (b) within the outer pipe; and expanding the inner liner former within the outer pipe to form the MLP. In this way, the conventional need to overcome problems with welding a number of pre-formed 12m or 24m bi-metallic pipe stalks to form a 1 km bi-metallic pipe are avoided, thus also avoiding weaknesses that can be a part of conventional stalk-welding processes for forming an MLP.

Filed: 1953-04-20
Abstract: 744.179. Brushes. OSBORN MANUFACTURING CO. April 20, 1953 [June 16, 1952], No. 10830/53. Class 19. A brush is formed by doubling brush material over a retaining ring and moulding about the doubled portion a back of metal, rubber or a synthetic resinous plastic material, the thickness of the back being no greater than that of the doubled portion of the bristles and the moulding material being caused to flow into the body of the brush material. As shown a die 2 is filled with wire bristles 1 through a funnel and the on upper die 5 having a spring loaded head 6 is lowered to bend the upper part of the wires outwardly over a retaining washer 4. The wires and washer are then inverted on to a further die 14 (Fig. 3), where the upper portion of the wires are bent outwards by a further die 16. Rings 18. 19, Fig. 5, of lead alloy are inserted before this operation and the pressure of the dies causes the alloy to flow into the interstices of the wires and form a unitary back. This may be reinforced by an eyelet inserted into the central hole of the back (Figs. 8 and 9, not shown). A cup brush may be formed by riveting the brush element into a cup. Fig. 10. The brush material may be wire. horse hair. tampico fibre, nylon or mixtures thereof in straight or crimped form and the back may be formed of nylon, cellulose acetate, rubber or neoprene. A number of brush sections may be secured together by a central eyelet to form a cylindrical brush.

Abstract: 317,337. Kuert, I. J. April 12, 1928. Moulding walls and roofs in situ. - Collapsable mould forms and cores for casting in situ combined walls and roofs having a series of cavities comprise moulding boards 30, Fig. 2, inserted in spaced channel rails 21, 22, Fig. 5, which are secured in pairs to ledgers 23 through which are passed clamping rods 51 to hold the forms on channel standards 45. Some of the rails have unequal flanges for inserting the boards. The rods 51 are adjustable by a screwed bush 56 and a socket 57. The joints between the boards are closed by angle-plates, and staging may be supported by brackets inserted into the bolt slots in the standards. The ground floor and footing are cast together : the wall cavities 76 formed by the collapsable box cores described below are closed at the top by pans 80, and the concrete roof and intermediate floors are cast in one with the wall-plate or binding course. Any wiring or plumbing fixtures are secured before the concrete is poured. Similar shuttering is used for the roof, and if desired the outer roof shuttering may be provided on the inside with corrugated members so that the cast concrete will simulate tiling. For curved portions of walls the shuttering is supported by rail members shown in Fig. 14 and formed of bent metal strips 91, 92 spaced by packing boards 94 and bolts 95. In a modification shown in Fig. 17, the upper channel of a rail consists of two angle-plates 98, 102, the latter being loose and clamped on the board 103 by a cam and lever 100. The collapsable box cores for forming the cavities in the walls and roof consist of four overlapping sides 132, Figs. 19 and 20, provided inside with angleirons 140, 150 through which extend rods 141 connected to flat or coiled springs 142; wedge surfaces 152 on the angle-irons coact with similar surfaces 156 on a bar 155, Fig. 22, which is moved longitudinally by a handle 165. The core is expanded against the pressure of the springs, and is collapsed by raising the bar 155, the inclined slots 160 therein causing the rods 141 to approach. The expansion and contraction of the core are assisted by a pair of auxiliary bars 176 slotted to engage the rods 141 and suspended from a cross bar 175. Several cores may be placed in alignment with a slack chain connecting the contiguous bars 155, 176, so that the cores collapse in succession. A pair of narrow bars 190, Fig. 27, joined by links may be used instead of a single operating bar. A similar but larger core is provided with intermediate side plates between the angled sides and similarly actuated.
