Patent number: 11930917Abstract: An apparatus for removal of debris from a debris-carrying brush comprising a housing having a brush aperture and an exhaust aperture, a debris-removal component having an array of cleaning elements, and a passive debris collection means, wherein, in a substantially dry environment free of water and cleaning solutions, the debris-removal component rotates such that the array of cleaning elements remove debris from a debris-carrying brush inserted into the apparatus through the brush aperture and brought in contact therewith, rotation of the debris-removal component causes the array of cleaning elements to induce an airflow towards the passive debris collection means, the airflow captures and entrains at least a portion of removed debris, and the entrained debris is deposited in the passive debris collection means.Type: GrantFiled: March 14, 2019Date of Patent: March 19, 2024Assignee: Comfortel Furniture Pte. Ltd.Inventors: Jono Chapman, Antony Stolfo, Lisa Feleppa, Sandra Sundelin, Matthew Hore, Barry Singer

Patent number: 11332993Abstract: A tool for penetrating a tubular as described. The tool comprises at least one length of linear shaped charge, a carrier adapted to support the/each length of linear shaped charge, and at least one detonation mechanism for detonating the/each length of linear shaped charge. Upon detonation of the/each length of linear shaped charge, a length of material is projected outwardly from the/each length of linear shaped charge towards an internal surface of die tubular, which is thereby penetrated. The at least one length of linear shaped charge is arranged such that, upon detonation, the trajectory of at least one portion of the projected material intersects the trajectory of at least one other portion of projected material at or adjacent the internal surface of the tubular.Type: GrantFiled: December 31, 2019Date of Patent: May 17, 2022Assignee: SPEX CORPORATE HOLDINGS LIMITEDInventors: Jamie Oag, Rae Younger, Andrew Pettitt, Barry Chapman, Simon McKay, David James Wilkie, Sidney Dantuma Johnston, John Fox

Patent number: 11193344Abstract: A tool for fracturing at least one tubular is described. The tool comprises a plurality of parallel columns of explosives and a detonation system configured to detonate the columns of explosives. The columns are arranged such that upon detonation, at least a portion of the Shockwave propagating in a direction outwardly from the tool from one column combines with at least a portion of the Shockwave propagating in a direction outwardly from the tool from another column to create a combined Shockwave of greater intensity than either of the Shockwaves which formed the combined Shockwave.Type: GrantFiled: December 21, 2017Date of Patent: December 7, 2021Assignee: SPEX CORPORATE HOLDINGS LTD.Inventors: Barry Chapman, David James Wilkie

Patent number: 10895124Abstract: A colliding tool for severing a target in a wellbore as described. The tool comprises a housing having a first chamber, the first chamber containing an explosive charge; and an at least one detonator connected to the explosive charge, the at least one detonator being insulated from temperature in the wellbore. In use, the at least one detonator is configured to simultaneously initiate a first explosion at a first end of the explosive charge and a second explosion at a second end of said explosive charge.Type: GrantFiled: February 22, 2017Date of Patent: January 19, 2021Assignee: SPEX CORPORATE HOLDINGS LTD.Inventors: Barry Chapman, Simon McKay, Andrew Pettitt, Jamie Oag, Rae Younger
