Kevin Francis Dolman, New South Wales AU
| Patent application number | Description | Published |
|---|---|---|
| 20080251507 | Hardfacing Ferroalloy Materials - A method of producing a carbide-containing ferroalloy welding consumable material and a method of producing a hardfacing on a suitable substrate using the consumable material are disclosed. The method of producing the consumable material comprises the steps of forming a homogeneous melt that has a required concentration of key elements, such as carbon, chromium and manganese, for the consumable material and forming a consumable material from the melt. | 10-16-2008 |

| 20100193184 | SYSTEM AND METHOD OF MONITORING FLOW IN A WELLBORE - A system and method for releasing a marker within a wellbore is provided. The system and method includes a sensor that detects movement or a position of the marker within the wellbore. The marker may be released in drilling fluid, for example, and may travel from the surface to the drill bit and return to the surface with cuttings. As an example, the markers are used to determine the flow of cuttings within the wellbore. | 08-05-2010 |
