Patent number: 7972518Abstract: A method for cleaning solids-laden aqueous fluids uses an apparatus comprising a settling tank having a sloping floor, which drops off into a collection area; primary and secondary mixing tanks, the lower regions of which are in fluid communication via fluid transfer means; and agitators in each of the mixing tanks. Solids-laden fluid is introduced into the primary mixing tank along with selected coagulant and/or flocculent chemicals, whereupon the agitator in the primary mixing tank is actuated to induce downward fluid flow toward the fluid transfer means and into the secondary mixing tank. The agitator in the secondary mixing tank is actuated to induce upward fluid flow in the secondary mixing tank, from which the fluid mixture overflows into the setting tank. Solids settle or precipitate into the settling tank, and then move downward along the settling tank's sloped floor and into the collection area, from which the solids can be removed for further treatment or disposal.Type: GrantFiled: June 30, 2010Date of Patent: July 5, 2011Inventors: Ambrose Ralph, Randy Wold, Roger Allard

Patent number: 7877837Abstract: A cleaning appliance of the cylinder type includes a main body and a hose and wand assembly including a telescopic wand movable between retracted and extended positions and a flexible hose having a first end connected to the main body and a second end connected to the wand. The wand and the main body include a retainer for releasable attaching the wand to the main body when the wand is in the retracted state and the hose passes around the main body. Alternatively, the wand and the main body include a retainer for releasably attaching the wand to an upper surface of the main body when the wand is in the retracted state. This construction provides a compact storage solution.Type: GrantFiled: August 21, 2003Date of Patent: February 1, 2011Assignee: Dyson Technology LimitedInventors: Peter David Gammack, James Dyson, Matthew James Roger Allard, Emma Jane Heatley

Patent number: 7111356Abstract: A dispenser for dispensing particulate cleaning material onto a floor surface includes a hopper holding the particulate material and having a dispensing aperture defined by a part that is movable with respect to the hopper itself. This moving part also imparts movement toward the dispensing aperture of particulate cleaning material in the hopper. The dispenser may be attached to a floor cleaning apparatus and includes a biasing device that that biases the movable part into a position which closes the dispensing aperture when the dispenser is removed from the floor cleaning apparatus.Type: GrantFiled: April 25, 2001Date of Patent: September 26, 2006Assignee: Dyson Technology LimitedInventors: Stephen Benjamin Courtney, Matthew James Roger Allard, Peter David Gammack

Patent number: 7036183Abstract: A vacuum cleaner (100) comprises a main body (3), separating apparatus, a flexible hose (20) having one end for coupling to an input of the separating apparatus and the other end terminating in a connecting part (40), a rigid pipe (9, 10) being selectively connectable to the main body (3) (see FIG. 2A) so as to provide a handle for the cleaner when connected to the main body (3), or a wand when released from the main body (3). The pipe (9) has an opening at each of first and second ends (16, 17) and a gripping portion (11) at the first end (17) for allowing a user to grasp the pipe (9). The hose connecting part (40) is connectable to the opening at either end (16, 17) of the pipe (9). Thus, the pipe (9) can be more conveniently used during a cylinder mode of cleaning.Type: GrantFiled: February 7, 2001Date of Patent: May 2, 2006Assignee: Dyson LimitedInventors: Peter David Gammack, Jonathan Paul Taylor, Matthew James Roger Allard

Publication number: 20050016087Abstract: Braces for bracing objects in structures against forces due to earthquakes are tested by subjecting components of the braces for attaching the braces to the object or structure to cyclic loading of approximately 15 cycles. The cyclic forces are applied to different samples of the components at differing angles, and a load rating is determined for each angle. Prior to cyclic testing, forces are applied monotonically to the components in both tension and compression, the flexible loading direction of the component is determined from the monotonic testing, and the deformation that the component can resist when a load is applied in cycles is estimated from the monotonic testing.Type: ApplicationFiled: July 21, 2003Publication date: January 27, 2005Applicant: FM GLOBAL TECHNOLOGIES, LLCInventors: Praveen Malhotra, Paul Senseny, Antonio Carlos Braga, Roger Allard

Publication number: 20040025284Abstract: A dispenser (50) for dispensing particulate cleaning material onto a floor surface comprises a hopper (52) for holding the particulate material. A part of the hopper (70, 71) is movable with respect to the hopper (52) to define a dispensing aperture (75) and to impart movement to particulate material in the hopper towards the dispensing aperture (75). The dispenser (50) is attachable to a floor cleaning apparatus (10). Biasing means (56) bias the movable part (70, 71) into a position which closes the aperture (75) when the dispenser (50) is removed from the floor cleaning apparatus. Thus, the dispenser (50) is self-closing.Type: ApplicationFiled: August 4, 2003Publication date: February 12, 2004Inventors: Stephen Benjamin Courtney, Matthew James Roger Allard, Peter David Gammack
