Patent number: 7922889Abstract: An anodic oxide film is formed on an aluminium or aluminium alloy work piece by forming an anodic oxide film on the work piece by AC electrolysis followed by subjecting the work piece to DC electrolysis. The AC anodizing step may be conducted at a voltage of 5 to 30V for 30 seconds to 10 minutes and the DC anodizing step may be conducted at a voltage of 5 to 30V for a period of 1 to 20 minutes. The anodic oxide coating is suitable for adhesive bonding of aluminium alloy work pieces.Type: GrantFiled: January 10, 2006Date of Patent: April 12, 2011Assignee: Short Brothers PLCInventors: Gary Critchlow, Ian Ashcroft, Timothy Cartwright, David Bahrani

Patent number: 5845668Abstract: A method is provided for replacing an existing service pipe carrying fluid to an outlet within a property with a replacement service pipe. In the method the outlet is disconnected within the property from the existing service pipe in such a way that both during and after disconnection fluid is prevented from escaping into the property. A desired length of replacement service pipe is then fed into the existing service pipe in such a way that during and after the feeding step fluid is prevented from escaping into the property. The outlet is then connected to the outlet end of the replacement pipe 2 in such a way that during the connection fluid is prevented from escaping into the property and after the connection step fluid is allowed to pass to the outlet solely by way of the replacement pipe.Type: GrantFiled: October 23, 1990Date of Patent: December 8, 1998Assignee: British Gas plcInventors: John Taylor, Michael Hicks, Richard Lamb, Robert Neal Bennett, Keith Nixon, Ian Ashcroft, Adrian Sydney Parkes, John Philip Smith
