Patent number: 9751116Abstract: Apparatus for removing material lining the inside surface of a cylindrical structure, the apparatus comprising: a support for supporting the structure in a horizontal orientation; an elongate horizontal boom for being inserted into the structure; a nozzle assembly connected to the boom member, the nozzle assembly comprising one or more nozzles wherein each nozzle is suitably spaced from the lining to deliver a jet of fluid under pressure to the lining; a conduit in fluid communication with the nozzle assembly suitable for delivering a flow of fluid to each nozzle under sufficient pressure to cut the lining material adjacent the nozzle; and a rotation mechanism cooperating with the support to passively enable the structure to being rotated while supported by the support or to actively impart rotation to the structure while supported by the support, wherein the rotation of the structure is about a central longitudinal axis of the structure.Type: GrantFiled: March 12, 2013Date of Patent: September 5, 2017Assignee: Mac & Mac Hydrodemolition Inc.Inventors: David MacNeil, Jerry MacNeil, Gordon MacNeil, Jesse MacNeil, Brett MacNeil, Vernon Bose

Patent number: 9671300Abstract: An electronic device may include one or more low-noise pressure sensors for measuring air pressure. The electronic device may include wireless communications circuitry for communicating with external devices also having pressure sensors. Pressure data gathered by an external device may be used as reference pressure data for the electronic device. For example, if both devices are located in the same building, both pressure sensors will detect similar pressure fluctuations due to doors opening and closing and temperature-control systems turning on and off. By subtracting the reference pressure data from the pressure data gathered by the electronic device, calibrated pressure data may be obtained and may be used to reliably detect vertical displacement changes of the electronic device. In other scenarios, the pressure data may be compared with the reference pressure data to determine whether the two devices are in the same room.Type: GrantFiled: March 16, 2015Date of Patent: June 6, 2017Assignee: Apple Inc.Inventors: Stuart K. Neubarth, Michael A. Lehr, David MacNeil, Henry H. Yang

Patent number: 7967390Abstract: A machine and method are disclosed for deconstructing walls and other substantially vertical surfaces. The machine comprises a static, stand-alone support-frame. A carriage is movably mounted on the support-frame, which carriage is operable to be raised and lowered along the support-frame adjacent to a workface. To the carriage are mounted one or more nozzles, preferably the nozzles are mounted to the carriage by means of a nozzle carrier that is operable to move back and forth along the length of the carriage. The nozzles are connected to a high-pressure supply of an erosive material, preferably water. The erosive material, when forced through the nozzles, form jet streams that are directed against the surface of the workface, thereby eroding the surface. Optionally, the invention comprises means of yawing or means of rotating the nozzles in order to access the sidewalls of the opening in the workface produced by the invention.Type: GrantFiled: May 25, 2007Date of Patent: June 28, 2011Assignee: Mac & Mac Hydrodemolition Inc.Inventors: Gerard MacNeil, David MacNeil, Gordon MacNeil, Vernon Bose

Patent number: RE44518Abstract: This application discloses an automated apparatus for scarifying the interior surface of a pipe or other similar elongated passageway. The apparatus includes a vehicle that propels itself down the inside of the pipe. A scarifying assembly is removably secured to the vehicle and uses arms to reach the walls of the pipe. At the end of each arm there is a fluid nozzle assembly equipped with fluid nozzles. The fluid nozzle assembly rotates or oscillates to scarify the pipe surface. The arms and fluid nozzle assembly interchange with other such scarifying assemblies depending on the shape or type of pipe and the desired scarifying technique. The apparatus is tethered to a source of fluid under pressure and a power source, both of which are located off-board the apparatus at a remote location.Type: GrantFiled: May 2, 2007Date of Patent: October 8, 2013Assignee: Mac & Mac Hydrodemolition Inc.Inventors: Gerard MacNeil, David MacNeil, Gordon MacNeil, Vernon Bose
