Publication number: 20110193299Abstract: A shrink-fit tool (21) includes a tool and a toolholder, one of the tool (23) and the toolholder (25) having a male shank portion (27) and the other one of the tool (23) and the toolholder (25) having a body portion (29) including female opening (31) for receiving the shank portion (27), the female opening (31) being adapted to change in size upon heating the body portion (29) to receive the shank portion (27) and upon cooling of the body portion (29) to clamp the shank portion (27) by an interference fit. The shrink-fit tool (21) also includes a mechanical retention member (33) disposed between the shank portion (27) and the body portion (29) for mechanically retaining the shank portion (27) in the female opening (31) so that the shank portion (27) is in its only predetermined orientation relative to the body portion (29).Type: ApplicationFiled: January 14, 2008Publication date: August 11, 2011Applicant: Seco Tools ABInventors: Alain Freyermuth, Macel Aarts

Publication number: 20110192009Abstract: A method for assembling a down hole drill comprises the steps of providing a cylindrical casing and a fluid distributor cylinder. Prior to assembly, the casing inner diameter is smaller than the fluid distributor cylinder outer diameter. A preassembly thermal treatment step is executed, in which the casing is heated to increase the casing inner diameter, or the distributor cylinder is cooled to decrease the distributor outer diameter, or both the casing is heated and the distributor cylinder is cooled. The distributor cylinder is then inserted into the cylindrical casing, and threaded into threads inside the cylindrical casing. Thermal energy is transferred between the cylindrical casing and the distributor cylinder, causing the casing inner diameter and the fluid distributor cylinder outer diameter to return to their preassembly sizes. This results in an interference fit along the outer surface of the distributor cylinder and the inner surface of the cylindrical casing.Type: ApplicationFiled: April 21, 2011Publication date: August 11, 2011Inventor: Timothy J.

Patent number: 7987576Abstract: A sleeved composite pipe or piling structure formed of an elongated polyethylene pipe or tube of high-density polyethylene (HDPE) or another polyethylene material installed over a substantially rigid and incompressible hollow metal pipe or solid wood core having an outer diameter that is the same or slightly larger than a normal inside diameter of the polyethylene pipe or tube when measured in a relaxed state at ambient temperature. The polyethylene pipe or tube is, for example, a HDPE 3408 material formed of virgin PE 3408 resin as specified in ASTM D3350 with UV protection, and the pipe is produced to ASTM A-3408. The metal pipe core can be ferrous or nonferrous pipe.Type: GrantFiled: September 28, 2007Date of Patent: August 2, 2011Inventor: William R. Watson

Publication number: 20110154984Abstract: A piston for an internal-combustion engine is made up of a first part and a second part. One of the two parts forms the piston head and the other part forms the piston skirt. A cooling chamber, which is delimited by material of the first part and by material of the second part, is configured in the piston. The two parts are joined together positively and non-positively via a press fit formed by a projection of the second part, with the projection engaging with a recess in the first part.Type: ApplicationFiled: August 22, 2008Publication date: June 30, 2011Applicant: ThyssenKrupp Metalurgica Campo Limpo Ltda.Inventors: Mauro Aparecido Ferreira De Oliveira, Heraldo Carlos Furquim, Joao Lester Garcia Lopes
