Multiple wires run parallel to one another. Each of wires is spaced apart from each adjacent wire at a distance less than a width of an encased microchip. Each of the plurality of wires includes a plurality of straight segments in a plane and bent segments that connect two of the plurality of straight segments. For each of the wires, each bent segments includes a first end, a second end, and a curved portion curved away from the plane. The first end is connected to at least one of the straight segments and separated from the second end a distance greater than the width of the encased microchip. The curved portion includes a diameter greater than the width of the encased microchip.

The two-stage soil sifting device comprises a support frame, an upper sifter, and a lower sifter. The support frame comprises a rectangular base with cross braces and four vertical uprights that support the upper sifter and the lower sifter at elevated positions. The upper sifter comprises an upper sifter frame and a first mesh having a first mesh spacing. The upper sifter is located above the lower sifter and may be pivotally inclined with respect to horizontal. The lower sifter comprises a lower sifter frame and a second mesh having a second mesh spacing. As unsifted soil placed upon the upper sifter is moved over the surface of the upper sifter some of it passed through the first mesh onto the lower sifter and then through the second mesh onto the ground, leaving debris on the first mesh and on the second mesh.

In a water-absorbent resin production apparatus for producing a water-absorbent resin by polymerizing a water-soluble ethylenically unsaturated monomer, a water-absorbent resin powder obtained by drying a water-absorbent resin composition with a dryer passes through a first powder flow path pipe, is discharged therefrom toward a classifier while a flow rate is regulated so as to a predetermined value by a powder flow rate regulating discharge member composed of a hopper and a rotary valve, and is classified by the classifier. In the water-absorbent resin production apparatus, a collector for collecting a powder aggregate composed of aggregated particles of the water-absorbent resin powder is disposed in the first powder flow path pipe. Accordingly, a water-absorbent resin in the form of a particulate powder from which the powder aggregate is removed can be produced at a high production efficiency.

A novel separation screen, a separation apparatus utilizing the separation screen, and a method for product separation are disclosed herein. The separation screen is formed from a first screening element having a first plurality of openings passing through the first screening element and a second screening element movably coupled to the first screening element. The second screening element is oriented parallel to the first screening element and has a second plurality of openings passing through the second screening element. The separation screen also includes an adjustment device integrated with at least one of the first screening element or the second screening element to control the effective size of the plurality of apertures in the separation screen.

A novel separation screen, a separation apparatus utilizing the separation screen, and a method for product separation are disclosed herein. The separation apparatus includes a housing defining a separation chamber having an inlet and a plurality of outlet orifices. A separation screen, which is located within the separation chamber, has a plurality of openings having fixed, non-uniform sizes. The separation apparatus also includes an adjustable feed placement device located upstream from the separation screen to direct a feed stream to a selected region of the separation screen to achieve a desired size distribution in each of the product streams.

This disclosure is generally drawn to systems, devices, apparatuses, and/or methods, related to monitoring a shaker and monitoring a room in which shaker(s) operate. Specifically, the disclosed systems, devices, apparatuses, and/or methods relate to controlling an actuated arm to inspect, remove, replace, repair, clean the shaker and/or screen assemblies based on monitoring the shaker and its screen assemblies, and to adjust or maintain shaker(s) in a defined area such as the room in which shaker(s) operate. While the examples disclosed herein generally describe shakers for separating solids from fluids, the present disclosure contemplates that other separation equipment (e.g., machines for separating solids from other solids) may also be monitored and controlled by the systems and methods described herein.

A screen panel has a pre-tensioned screen with a polished metal plate mounted to the top of the frame to eliminate all the exposed surface areas of epoxy which secures the screen to the screen panel frame. The metal plate also provides an edge against which a silicone bead may be seated to provide a much cleaner and finished looking panel which is anticipated to meet the standards set forth by the USDA. Additionally, the spatial positioning of the plate atop the screen material and screen frame allows for a clean and smooth transition across the components and one which may accept a finished bead of silicon or other material for reducing and/or eliminating sites for mold growth or other containments thereby enhancing the ability to clean and sterilize the screen panel for the processing of various materials.
