Publication number: 20090293733Abstract: Various forms of apparatus (1) for preparing and dispensing beverages, preferably based on coffee, can receive instructions from a customer and deliver the beverage automatically. The apparatus is preferably capable of fully automatic cleaning in a cleaning cycle in which a cleaning agent is flushed through the lines (62, 64), and the apparatus is preferably arranged to ensure that not only are the lines cleaned properly but that no cleaning agent can be dispensed. The apparatus includes a brewer assembly (78) having a chamber (81) in which freshly ground coffee can be introduced and either espresso or filter coffee can be automatically prepared by passing hot water through the chamber and removing the spent coffee grounds. The coffee may be stored as coffee beans in sealed containers (208) that can automatically be pierced to release the beans which are ground immediately before preparation of the beverage.Type: ApplicationFiled: February 28, 2006Publication date: December 3, 2009Applicant: COFFEE NATION LTD.Inventors: Scott Martin, Steve Irwin, Andrew Chi Wai Yau, David William Smith, Jake Philip Tuner, John McGarva, Patrick Sweeting, Simon James Naylor, David William Harper, David Bradshaw, Michael Robert Nelson, Martyn Dawes, Damyn James Musgrave

Patent number: 7351814Abstract: This invention provides novel libraries of olfactory receptor odorant/ligand-binding domains and methods of making and using them. The invention also provides libraries of vectors and cells comprising these nucleic acid constructs. The compositions and methods of the invention are used to identify novel ligand-binding domains for olfactory neuron odorant receptors and their ligands. Thus, the compositions and methods of the invention can be used to generate novel odorants, to screen for toxic odorants, or to manipulate an animal's olfactory response.Type: GrantFiled: October 25, 2005Date of Patent: April 1, 2008Assignee: The Johns Hopkins UniversityInventors: Randall R. Reed, King-Wai Yau, Dietmar Krautwurst

Publication number: 20070075104Abstract: A pinch clip garment hanger includes a cross member, a hook member, and at least one pinch clip member. The pinch clip member has a fixed jaw member integrally molded to the cross member, a moveable jaw member pivotally secured to the fixed jaw member, and a biasing spring that holds the jaw members together. The fixed jaw member has a first surface facing the moveable jaw member, and the moveable jaw member has a second surface facing the fixed jaw member. The first and second surfaces are pressed together by the biasing spring to hold the garment that is positioned between the fixed and moveable jaw members.Type: ApplicationFiled: October 2, 2006Publication date: April 5, 2007Inventor: Wai Yau

Publication number: 20070017898Abstract: A method and apparatus for etching photomasks is provided herein. In one embodiment, a method for etching a photomask includes placing a reticle upon a pedestal of a processing chamber, forming a plasma from a process gas, preferentially allowing neutrally charged radicals to pass through the plate relative to ions present in the plasma and etching a layer disposed on the reticle. In another embodiment, an apparatus for etching a photomask includes a process chamber having a substrate support pedestal disposed therein that is adapted to receive a photomask reticle thereon. An RF power source is provided for forming a plasma within a processing volume of the chamber. A plate having a plurality of holes formed therein is supported in the processing volume in an orientation substantially parallel to and a spaced apart from both the substrate support pedestal and a lid of the processing chamber.Type: ApplicationFiled: September 11, 2006Publication date: January 25, 2007Inventors: Ajay Kumar, Madhavi Chandrachood, Scott Anderson, Peter Satitpunwaycha, Wai Yau

Publication number: 20020048812Abstract: Olfactory receptor cell lines are conditionally immortalized. Under permissive conditions they proliferate. Under nonpermissive conditions the cells differentiate into mature functional Olfactory Receptor Neurons (ORNs) expressing multiple olfactory neuron-specific markers. Exposure of cells of the clonal lines to a battery of odorants indicates a functionally heterogeneous population, in which approximately 1% of the cells respond to any particular single odorant. This heterogeneity suggests the potential of the cells of the cell line to express multiple different receptors and demonstrates that the cell line is an appropriate model for native Olfactory Receptor Neurons.Type: ApplicationFiled: January 12, 2001Publication date: April 25, 2002Inventors: Gabriele V. Ronnett, Robert Duncan Barber, King-Wai Yau
