Title: Sonar apparatus
Inventor: BLAKE COLIN DESMOND
IPC: G01S15/42
Filed: 2012-03-15
Abstract: Sonar apparatus locating and displaying features on the underwater floor in front of a boat comprises port and starboard transducer units 2, 4 each containing a plurality of transducer arrays. A transducer interface 6 and a visual processor 8 process signals from the transducer arrays to generate image data that is displayed on display 10. The transducer arrays emit sound wave beams into non-overlapping segments of water 12, 14, 16, 18, and the sea bed within these segments reflects the sound waves back to the transducer arrays, which convert them to electrical signals. The electrical signals are processed to calculate a three-dimensional position of each point on the underwater floor within the segments 12, 14, 16, 18 which reflected the sound waves. The apparatus performs interpolation using the positions of the reflecting points within the segments to calculate three-dimensional positions of points on the underwater floor between these segments. The three-dimensional positions of the points are then used to generate image data for display showing the underwater floor in front of the boat 50.

IPC: B29C67/00
Filed: 2012-10-02
Abstract: A method of manufacturing a three-dimensional article comprises printing one or more ink layers 504 onto a base. At least one ink layer includes a gap. A pool of un-cured resin 505 is formed within the gap and at least a portion is cured 506 to form a solid part of the article. The pool is preferably formed by submerging the partially formed article in a bath 503 of uncured resin following each printing step and raising it prior to curing. A squeegee may remove excess resin prior to curing. Further layers of ink may be printed onto previously printed ink and/or cured or uncured resin and the steps repeated. Several inks of different colours may be used and the article surface or boundary may have a colour corresponding to the ink or inks. The resin is preferably cured by exposure to radiation such as UV light or a laser. Alternatively the ink may be used to define the boundary area of each layer of an article and the resin may be deposited within the area by the printing head used to deposit the ink. The resin may be deposited such that the complete internal edge of the ink boundary contacts uncured resin.

Title: Repair of pipes and pipelines
Inventor: POTTER MARK THOMAS WILLIAM
IPC: F16L55/16
Filed: 2013-06-18
Abstract: In order to repair fractures on a T joint between a primary pipe 1 and a lateral pipe 2, a top hat patch 10 of absorbent material is impregnated with curable resin and positioned on an inflatable bladder 20. The bladder 20 and patch 10 are positioned at the intersection 3 and inflation of the bladder 20 holds the impregnated patch against the intersection 2. Once the resin has cured, the resin and patch 10 form a rigid watertight layer. During the repair, absorbent strips 32 made from the same material as the patch 10 are wrapped around the brim portion 12 at either side of the tube portion 12 and impregnated with resin. Once the strips 32 are in place, elastic retaining bands 33 are placed around the strips 32. Once the resin has cured, the strips 32 overlie the bands 33 and thus the bands 33 cannot present an enduring snagging hazard.

Title: Compensating for thermal expansion via controlled tube buckling
Inventor: CAPLES MARK A
IPC: F23R3/32
Filed: 2014-12-23
Abstract: A fuel injector 10 for a gas turbine engine and a method of use. The fuel injector includes a fuel tube 14 for receiving fuel and which extends from an inlet fitting 12 through an internal bore 18 of an injector support 16 to an outlet fitting 20. The injector support is made of material that has a greater coefficient of thermal expansion than the material of the fuel tube, and at room temperature the fuel tube is under a compressive stress such that it is buckled 30. At engine operating temperature, the differential thermal expansion between the fuel tube and the injector support results in the injector support expanding more than the fuel tube, and thus the fuel tube is relieved of compressive stress. During manufacture of the fuel injector, the assembled injector support and fuel tube are heated to provide the initial thermal expansion, and while differentially expanded, the tube is fixed within the injector, for example by welding or brazing, and when cooled, buckling results.

Title: Improving the bending behaviour of mechanically-lined rigid pipe
Inventor: GRÉGORY ALEXANDRE TOGUYENI
IPC: F16L58/08
Filed: 2014-12-24
Abstract: A method of making mechanically-lined pipe 10 comprises primary expansion by plastically expanding a liner sleeve 14 within an outer pipe 12, under lining pressure applied internally to the liner sleeve 14. On relieving the lining pressure, elastic radial contraction of the outer pipe 12 makes a mechanical bond 26 between the outer pipe 12 and the liner sleeve 14. Then, secondary expansion of the outer pipe 12 is performed under fixing pressure, which may be greater than the lining pressure, applied internally to the liner sleeve 14 at an end portion of the pipe. This makes or strengthens a mechanical bond at the end portion. The resulting pipe joint comprises an end portion and a body portion inboard of the end portion. The body portion has a first, lesser bonding pressure between the outer pipe 12 and the liner sleeve 14. The end portion has a second, greater bonding pressure between the outer pipe 12 and the liner sleeve 14. An overlay can be applied to the end portions, chemically or metallurgically bonding the liner sleeve to the outer pipe.
