Patent number: 9839087Abstract: A lighting system (1) has a first lighting circuit (2) configured to provide a first predetermined level of lighting intensity. The first lighting circuit (2) is configured to receive power from a mains electricity supply (3) or from a battery source (4) if the mains supply is unavailable. The first lighting circuit (2) is connected to at least one first Light source (5) and configured, when actuated, to provide lighting at the first predetermined level of lighting intensity. At this time, the first light source is in either an on or off state or a level of light required to raise ambient light level above a predetermined level. The system (1) further has a second lighting circuit (13) configured to provide lighting at least a second predetermined level of lighting intensity. The second lighting circuit (13) is configured to receive power from the mains electricity supply (3) and is connected to at least one second light source (14).Type: GrantFiled: January 18, 2012Date of Patent: December 5, 2017Assignee: Enlighten Australia PTY LTDInventor: David Whitfield

Publication number: 20130189245Abstract: The present invention relates to the use of toxoids prepared using a-dicarbonyl toxoiding reagents such as glyoxal, butanedione and phenylglyoxal. The toxoids may be prepared with low concentrations of toxoiding reagent and in short periods of time, often in as few as 24 hours, making the toxoiding reagents particularly advantageous when compared with traditional formaldehyde toxoiding. Toxoids prepared using dicarbonyl reagents such as phenylglyoxal are described and claimed as are pharmaceutical and vaccine compositions comprising the toxoids, methods of treatment using such compositions and antibodies generated by immunisation with the toxoid and methods of treatment using the antibodies so prepared or fragments of such antibodies.Type: ApplicationFiled: July 18, 2011Publication date: July 25, 2013Inventors: Lucy Jane Cork, Gary John Phillips, Gareth David Griffiths, David Whitfield

Patent number: 4046538Abstract: The disclosure embraces a method of and apparatus for distributing linear groups of fibers onto a moving collector which include engaging and advancing groups of fibers by rotating pull wheels, disengaging the groups of fibers from the pull wheels by oscillating and rotating members associated with the pull wheels, oscillating the members by cam-actuated systems of linkage to control disengagement of the groups of fibers from the pull wheels and effect distribution of the groups of fibers on the collector, and applying pressure on the linkage systems opposing the operation of the systems to substantially eliminate lost motion in the linkage systems and thereby promote oscillatory motion accuracy of the fiber disengaging members whereby the collected body of fibers is endowed with substantially uniform characteristics.Type: GrantFiled: April 19, 1976Date of Patent: September 6, 1977Assignee: Owens-Corning Fiberglas CorporationInventor: David Whitfield Thomas
