摘要： Devices and methods for improved separation of small particles from other stock. The device includes a sifting tray assembly and means for vibrating the screen of the shifting tray assembly for separating components and a cryogenic fluid source and injection system for freezing the small parts to the point where they are solid enough to pass through the screen without adhering to the screen. The method entails use of the system to separate small particles in sifting trays while spraying the stock with a cryogen such as liquid nitrogen.

摘要： The present invention relates to apparatuses for distributing build powder in powder-layer three-dimensional printers (2) and for the collection of particulates of the build powder that have become suspended in the gaseous atmosphere in the vicinity of the build platform of the three-dimensional printer. These apparatuses include recoaters (20) that are particularly useful in providing uniform distribution of fine build powder across the width of the build platform or powder bed. The present invention also includes powder-layer three-dimensional printers (2) which comprise such apparatuses for distributing build powder and/or apparatuses for collecting such suspended particulates. The improved fine powder recoater (20) uses an ultrasonic transducer (30) to move powder through a sheet screen (28). The sheet screen (28) may be presented to the powder fed onto it in a narrow dispensing slot to limit the flow rate of powder from the dispenser and to provide control over the amount of powder dispensed. The width of the slot may extend to cover the entire build box fill zone. The ultrasonic transducer (30) is preferably adapted to periodically sweep through a range of frequencies during operation. The ultrasonic vibration system may be augmented with a low frequency vibration system. The dust collection system (160) draws air from the perimeter of the build box (172) down through the deck plate (170) of the printer (2) and out of the printer's housing (164) to an external dust collector (250).

摘要： A disclosed screen assembly includes a frame and a tensioned molded polyurethane screen attached to the frame. The frame has a perimeter that is a circle, square, rectangle, triangle, pentagon, hexagon, or other multi-sided polygon, and the screen may have similarly shaped apertures. The frame includes a support grid structure bounded by the perimeter and the screen may either be attached only to the perimeter of the frame, or may be attached to the perimeter of the frame and to one or more locations of the support grid structure. The screen may include uniaxial or biaxial reinforcement members that are integrally molded with the screen, and the tensioned screen may include tension along a direction that is parallel to, or perpendicular to, a direction of the reinforcement members. A disclosed method includes applying tension to a molded polyurethane screen and attaching the tensioned molded polyurethane screen to the frame.

摘要： Deblinding apparatuses and deblinding methods are provided. A deblinding apparatus may include a support frame including a grid structure and multiple compartments. Multiple compartments may be formed by a respective portion of the grid structure and a respective set of support members. Further, multiple scattering members may be disposed within a compartment. Scattering members be removably affixed to a portion of the grid structure that forms a part of a compartment. Multiple unsecured objects may be placed within a compartment. When attached to a screen and in response to movement of support frame, at least one unsecured object of the multiple unsecured objects may collide with a first scattering member and with a surface of the screen to thereby cause deblinding of the screen. Sizes, shapes, masses, and morphologies of unsecured objects may be designed to optimize collision rates of unsecured objects with scattering members and with the screen assembly.

摘要： A plant product extraction apparatus or extractor is provided for separating or grading fine particles from a larger portion of material, such as separating trichomes from a stalk or flower of a plant. The apparatus imparts a plurality modes or patterns of oscillations and vibrations to a particle separator or sieve that holds the plant matter. A motor drives a back and forth motion to a support platform supporting a sieve. The sieve is constrained by a retention tray that is supported by the support platform. Vibratory motors provide rapid shaking vibration through the retention tray to the sieve. Agitators may be placed inside of the sieve to facilitate the separation of the plant materials. The various motors and locomotion patterns facilitate the separation of finer plant materials from a larger portion of a plant.
