Abstract: A handheld device for use by a user or a consumer, that includes a custom application and is capable of interacting with its physical environment is disclosed. The device utilizes a positioning subsystem located in the device, and a priori or dynamic knowledge locations of stores, items and other geographic position markers. The devices assists the user in identifying and purchasing items of interest, in real time with relevant and timely location based information.

Abstract: A winch assembly (10) comprising a winch pedestal (12), a winch drum motor (14) mounted on a winch drum drive shaft (15) and configured to be driven to rotate on the winch pedestal about a winch axis and a spooling carriage (20) supported by at least one support arm (22, 24). The at least one support arm is pivotally connected to the winch pedestal via a hub. The hub surrounds the winch axis and pivotal movement of the at least one support arm rotates the spooling carriage relative to the winch pedestal.

Abstract: A mixing method uses, and a colloidal grout mixing apparatus comprises, an upright cylindrical vessel in which a mixer is located. The mixer comprises a shaft extending substantially co-axially with the longitudinal axis of the vessel, and a paddle assembly mounted on the shaft. The paddle assembly produces a vortex in liquid in the vessel, and also provides a high shear region near the base of the vessel. A non-shear pump is connected to the base to discharge grout from the vessel. The grout may be discharged to a drum containing radioactive waste and mounted on a vibratory platform.

Abstract: A process wherein solid particles are coated with either liquids or solids while the particles are moving as a uniform layer over the surface of a rotating body and subsequently discharged from the surface by centrifugal force. Two forms of coating apparatus designed to coat prills are shown, the preferred apparatus having a flexible conical disc carrying a layer of existing material which touches the rim of the rotating body from which the solid is discharged.
