Publication number: 20100041322Abstract: A method for drilling or cutting a pin surrounded by solid material includes the use of a water jet tool having a nozzle that is arranged at an angle with respect to a main body of the water jet tool. The water jet is directed over a portion of the surface of the pin, and removes that portion thereby fragmenting the pin. In order to minimise damage to the surrounding material, the portions removed touches the interface between the pin and the surrounding solid material at a minimal number of points and over a minimal extent of the interface. The method is applicable in particular to the removal of pins used in a press-fit for the securing of blades on a turbine rotor. The method facilitates “in situ” removal of pins within a confined space in a short time and at reduced cost.Type: ApplicationFiled: October 23, 2009Publication date: February 18, 2010Applicant: ALSTOM TECHNOLOGY LTDInventors: Roland Moser, Christopher John Hulme

Publication number: 20100024619Abstract: A method of machining a solid material using a water jet discharging from a nozzle is specified, wherein the water jet contains ice crystals and impacts on the solid material. In this case, a medium which is gaseous under standard conditions is dissolved in water at a mixing stage under pressure (1-150 bar) and is then compressed to 1000-4500 bar and pressed through a nozzle, under conditions which allow the dissolved gaseous medium to bubble out after leaving the nozzle, whereupon the heat of solution is withdrawn from the water and the ice crystals are formed.Type: ApplicationFiled: June 22, 2007Publication date: February 4, 2010Applicant: UNIVERSITAT INNSBRUCKInventors: Thomas Loerting, Bertel Erminald

Publication number: 20090250231Abstract: In one embodiment of the present invention, equipment for making holes by cutting in walls etc. is disclosed in case of fire in spaces in buildings etc. for fire fighting. The equipment includes a vehicle-mounted pressure source for pressurised extinguishing liquid, a lance carried by the operator with his hands and provided with an extinguishing nozzle, and a tubing between the pressure source and the extinguishing nozzle for supplying the extinguishing liquid. The extinguishing liquid flows as a jet out of the extinguishing nozzle and towards the wall etc. to cut the wall for making the hole and, when cutting through, be injected into the space on fire and extinguish the fire. The equipment also includes a vessel carried by the operator on his back and containing an additive, the vessel being connected to the extinguishing nozzle for regulated supply of the additive to the extinguishing liquid for improving the cutting and/or extinguishing effect.Type: ApplicationFiled: September 5, 2006Publication date: October 8, 2009Inventor: Lars G.

Publication number: 20090223336Abstract: A cutting apparatus cuts a lateral wall of a manhole to form a hole on the lateral wall of the manhole. A circular pipe is harmonized with a main pipe and fixedly disposed therein. A rotary ring configured so as to be able to rotate along the periphery of an opening in the manhole about the axial center of the main pipe is mounted on the circular pipe. A pressurized fluid material or pressurized granular material is sprayed from a nozzle held in the rotary ring. The rotary ring is rotated and the lateral wall of the manhole is cut through along the periphery of the opening in the manhole by the fluid material or granular material sprayed from the nozzle. Since the cut portion is shaped as a circle symmetrical about the axial center of the main pipe, it is possible to form a circularly shaped cut-through part centered along the periphery of the opening in the manhole without accidentally breaking or damaging the lateral wall thereof.Type: ApplicationFiled: March 6, 2009Publication date: September 10, 2009Inventors: Takahiko Tsujisawa, Takao Kamiyama

Publication number: 20090223335Abstract: A main pipe is lined using a pipe lining material that blocks the opening of a lateral pipe branching from the main pipe. An in-pipe work robot is provided with a cutting nozzle for spraying a pressurized fluid material or pressurized granular material onto the pipe lining material of the main pipe. The cutting nozzle is moved to a predetermined position inside the main pipe and rotated about a vertical axis by a rotary mechanism to cut the lining material between the first and second pipes by the pressurized fluid material or pressurized granular material sprayed from the cutting nozzle in order to form an opening for communicating the main pipe with the lateral pipe. The cutting nozzle can be moved in desired positions to drill holes accurately without damaging the internal peripheral surface of the lateral pipe.Type: ApplicationFiled: March 6, 2009Publication date: September 10, 2009Inventors: Takahiko Tsujisama, Takao Kamiyama, Masao Ueno
