Patent number: 10544028Abstract: The present invention is directed to a beverage dispensing system including at least one beverage dispensing container, a computing device and a base unit upon or within which, in use, the at least one container is positioned. The at least one container includes a reservoir of beverage, a communication element for storing data indicative of contents of the beverage dispensing container, a manually actuatable dispensing valve selectively controlling flow of beverage from the reservoir to a container outlet, and pressurizing means for pressurizing beverage against the dispensing valve such that when the dispensing valve is opened beverage flows from the reservoir and out the container outlet.Type: GrantFiled: December 23, 2014Date of Patent: January 28, 2020Assignee: Pernod Ricard SAInventors: Ian Allan Guy, Sarah Helen Liddell, Steven John Kelly, James Ashley Gadd, Tom Foran, Alain Duffosse, Vlastimil Spelda, Amaury Cointreau

Publication number: 20170156525Abstract: This invention is directed to a duckbill valve arrangement (10) for a beverage dispensing container (70). The arrangement (10) includes a tube (11) having a resilient tube wall (12) with an outer surface (15) and defining an internal passageway (13). The arrangement (10) further includes a duckbill valve (30) mounted within the passageway (13). The duckbill valve (30) includes a resiliently closable valve mouth (41) arranged to be opened upon compression of the tube (11). At least one groove (20, 21) extends along the outer surface (15) of the tube wall (12) for reducing the force required to compress the tube (11) and open the duckbill valve (30).Type: ApplicationFiled: June 23, 2015Publication date: June 8, 2017Inventors: Ian Allan GUY, Sarah Helen LIDDELL, Steven John KELLY, James Ashley GADD, Tom FORAN, Stephen Philip DE SAULLES

Patent number: 7921962Abstract: In an appliance, such as a cyclonic vacuum cleaner, a motor is arranged to drive an impeller fan located in a motor and fan unit. The rotation of the impeller may cause nuisance tones to be generated. A silencing arrangement is provided to control such noise and includes a plurality of discrete passive silencers in the form of tube silencers arranged in a first set and a second set. The tube silencers have open end portions arranged to face the fan and the silencers of the first set are spaced from the silencers of the second set in both axial and radial directions. This combination gives the same effect as an array of closely spaced tube silencers—however, by spacing the silencers in two directions, fluid is allowed to flow freely.Type: GrantFiled: February 22, 2010Date of Patent: April 12, 2011Assignee: Dyson Technology LimitedInventor: Sarah Helen Liddell

Patent number: 7891050Abstract: A handle assembly for a cleaning appliance includes a handle portion and a tubular wand having an open end configured to receive tools or other accessories when the cleaning appliance is in use. The handle assembly also includes a wand cap which is movable between a first position in which the wand cap covers the open end of the tubular wand and a second position in which the open end of the tubular wand is not covered by the wand cap. The wand cap is releasably connected to the handle portion or the tubular wand in a snap-fit manner. This provides an advantageous construction which reduces the risk of damage and the cost of repair.Type: GrantFiled: July 1, 2005Date of Patent: February 22, 2011Assignee: Dyson Technology LimitedInventor: Sarah Helen Liddell
