Patent number: 9797411Abstract: A ceiling fan includes an annular nozzle having an inner wall, an outer wall extending about the inner wall, an air inlet for receiving an air flow, an air outlet for emitting the air flow, and an interior passage located between the inner and outer wall for conveying the air flow to the air outlet. The inner wall defines a bore through which air from outside the nozzle is drawn by the air flow emitted from the air outlet. A support assembly supports the nozzle on a ceiling and includes a ceiling mount for mounting the ceiling fan on a ceiling, an arm having a first end connected to the ceiling mount, and a body connected to a second end of the arm and the annular nozzle. The body is pivotable relative to the arm about a pivot axis to move the annular nozzle between a raised and lowered position.Type: GrantFiled: November 25, 2011Date of Patent: October 24, 2017Assignee: Dyson Technology LimitedInventors: James Dyson, Neil Andrew Stewart, Rodney James Brown

Patent number: 7997295Abstract: A supplementing water supply controller which provides water from a supplementing water supply to an outlet in preference to a main water supply, wherein if there is insufficient supplementing water to meet demand, the main water supply flows through the controller to the outlet, whereas if there is sufficient supplemental water to meet the demand, a supplementing water pump is activated and the pressure of the supplementing water is raised above a threshold level at which it moves an actuator mounted by two diaphragms to block the main water supply, so that the supplementing water can flow to the outlet. The actuator has a larger effective area at its low pressure end than at its high pressure end, so that the supplementing water threshold pressure level for moving the actuator to block the main water supply is less than the main water pressure.Type: GrantFiled: July 22, 2005Date of Patent: August 16, 2011Assignee: Davey Products Pty LtdInventors: Rodney James Brown, Da-Wei Zhang

Publication number: 20080128025Abstract: A controller (10) provides water to outlet (22) from a supplementing water supply (e.g. from a rainwater tank) attached to passage (18) in preference to a main water supply (e.g. from a mains water supply) attached to passage (14). If there is insufficient supplementing water to meet demand, then mains water flows through passage (14), around partition (36) and to outlet (22). If there is sufficient supplementing water for the demand, a supplementing water pump is activated, and the pressure of supplementing water in passage (18) is raised above a threshold level at which it is able to move piston (28) against mains pressure to seal against valve seat (34) and block the mains supply, so that supplementing water can flow to outlet (22) via one-way valve (42).Type: ApplicationFiled: July 22, 2005Publication date: June 5, 2008Applicant: DAVEY PRODUCTS PTY LTDInventors: Rodney James Brown, Da-Wei Zhang

Patent number: 6382689Abstract: A security device for a sliding door or window assembly having a sliding panel in a frame. The device comprises a bar. A structure is for pivotally attaching a first end of the bar to an inner side edge of the panel. A fixed pin is secured longitudinally to a second end of the bar. The bar can pivot down one hundred and eighty degrees from an upright storage position to a downward locked position, allowing the fixed pin to engage with one of a plurality of spaced apart holes in a bottom track of the frame, thereby preventing the panel from being opened.Type: GrantFiled: May 26, 2000Date of Patent: May 7, 2002Inventor: Rodney James Brown
