    摘要: A method and process for computer-controlled manufacture of three-dimensional objects involves dispensing a layer of a first material, such as a liquid, insoluble material onto a platform at predetermined locations corresponding to a cross-section of the object, which then hardens. A second medium, preferably water soluble, is then sprayed onto this layer to thereby encapsulate the hardened insoluble media. The uppermost surface of this encapsulant is planned, thus removing a portion of the encapsulant to expose the underlying insoluble material for new pattern deposition. After the resulting planing residue is removed, another layer of liquid, insoluble media is dispensed onto the planned surface. The insoluble media can be of any color and may vary from layer to layer, and from location within a layer to location with a layer. These steps are repeated, until the desired three-dimensional object, surrounded by a mold, is completed. At this point, the object is either heated or immersed in solvent, thereby dissolving the mold and leaving the three-dimensional object intact. Other system methods, and processes are also disclosed.

    摘要: An object produces from a computer data base by representing the object in the data base as a solid voxels surrounded by support voxels within a volume. The data base representation of the object as the solid voxels is converted to a data base representation of the object as a shell of solid voxels surrounding filler support voxels, and the object from said converted data base representation is constructed in a layerwise fashion. A first material is dispensed in liquid form at selected locations of a target surface, and the selected locations correspond to the shell locations of a cross-section of an object. The first material solidifies after being dispensed; a second material is applied at locations of said target surface other than the shell locations at which the first material is dispensed, to form another target surface. The dispensing and applying is repeated to form an object comprising a shell of the first material surrounding said second material, and surrounded by the second material. The portion of said second material surrounding said shell is removed, relative to the first material, to leave an object formed of a shell of the first material surrounding a portion of the second material.

    摘要: A method and process for computer-controlled manufacture of three-dimensional objects involves dispensing a layer of a first material, such as a liquid, insoluble material onto a platform at predetermined locations corresponding to a cross-section of the object, which then hardens. A second medium, preferably water soluble, is then sprayed onto this layer to thereby encapsulate the hardened insoluble media. The uppermost surface of this encapsulant is planarized, if necessary, for example by way of a mill cutter, knife, roller or thermal bar, thus removing a portion of the encapsulant to expose the underlying insoluble material for new pattern deposition. The dispensing of the first and second materials, and the planarization, may be performed in a single pass by an integrated printhead. After the resulting planing residue is removed, another layer of liquid, insoluble medium is dispensed onto the planed surface. These steps are repeated, until the desired three-dimensional object, surrounded by a mold, is completed. At this point, the object is either heated or immersed in a solvent, thereby dissolving the mold and leaving the three-dimensional object intact; alternatively, the second material may remain in place to form a composite structure such as a printed circuit board. A method is also disclosed which converts a CAD data base representing a solid object into one representing a filled shell, reducing the amount of object material required.

    摘要: An apparatus and method for transporting a flow of air and particulates through a vacuum cleaner. The apparatus can include an airflow propulsion device that draws the flow through an intake aperture and propels the flow through two upwardly-extending conduits toward a filter element housed in a filter housing. The conduits can have generally smooth internal walls and a combined flow area less than the flow area of the intake aperture to accelerate the flow upwardly toward the filter element.

    摘要: A sealable debris bag includes a bag body having an opening, and a plate member attached to the bag body proximate the opening. First and second portions of the plate member are pivotable along a fold-line so that the first portion is engageable with the second portion to substantially seal the opening. A tab on one side of the fold-line engages a notch on the other side of the fold-line to secure the device. The fold-line can be formed in the plate member, to define the first and second portions where the portions are contiguous, or can be formed in the bag body where the portions are non-contiguous. The opening may be formed in a flexible lateral wall of the bag body, or alternately, in an end portion of the bag body. A complimentary alignment structure on plate member mates with an alignment structure on a vacuum to ensure proper alignment of the debris bag on the vacuum.

    摘要: An apparatus and method for transporting a flow of air and particulates through a vacuum cleaner. In one embodiment, the apparatus includes an intake body having an intake opening configured to receive the flow of air into particulates. An airflow propulsion device is coupled to the intake opening to draw the flow through the intake opening and through a flow passage having an approximately constant flow area. The flow continues through one or more conduits from the propulsion device to a filter element housed in a filter housing where the particulates are separated from the flow of air.

    摘要: A high efficiency motor for low velocity and high volume fans and other applications includes an armature, a stator and a motor shaft. The armature is made from plates that collectively have a stack height that give the armature a thickness. The plates are keyed with a keyway and the motor shaft has a key to increase alignment accuracy and armature assembly efficiency. An armature aspect ratio is determined by the armature diameter divided by the armature thickness. Similarly a stator aspect ratio is determined by a stator diameter divided by a stator thickness. The armature and the stator aspect ratios are selected to increase torque output and lower rotational speed of the motor for various power output levels. Magnetic permeability properties of the armature and stator is selected to increase operating efficiency of the motor and decrease motor size. When incorporated into devices such as vacuum cleaners, carpet extractors, floor buffers, and yard blowers, the motor decreases unwanted noise and increases operating efficiency.
