Abstract: A method for enrichment of a mixture of graphene nanoplatelets (GNP) may include providing GNP into a column. The method may also include passing the GNP through an electrostatic field in a drift column to separate thinner GNP from thicker GNP to increase the content of the thinner GNP. The method may further include coupling a feeder to the drift column to accept the GNP and providing electrical charge to the GNP by the drift column with a charging module. The method may still further include generating the electrostatic field with an electrostatic field generator in the drift column to increase the content of GNP with smaller thickness.

Abstract: A plastic item, such as a beverage bottle, can convey two distinct digital watermarks, encoded using two distinct signaling protocols. A first, printed label watermark conveys a retailing payload, including a Global Trade Item Number (GTIN) used by a point-of-sale scanner in a retail store to identify and price the item when presented for checkout. A second, plastic texture watermark may convey a recycling payload, including data identifying the composition of the plastic. The use of two different signaling protocols assures that a point-of-sale scanner will not spend its limited time and computational resources working to decode the recycling watermark, which may lack data needed for retail checkout. In some embodiments, a recycling apparatus makes advantageous use of both types of watermarks to identify the plastic composition of the item (e.g., relating GTIN to plastic type using an associated database), thereby increasing the fraction of items that are correctly identified for sorting and recycling.

A first gate member movable around a first axis is provided below a coin conveyance path. The first gate member is moved by a first position switching device among a default position where a gate is closed, a first switched position that allows a coin to drop through the gate to move in a first direction, or a second switched position that allows a coin to drop through the gate to move in a second direction. When a coin has a first (or second) denomination, the first gate member is moved to the first (or second) switched position. When a coin does not have the first and second denominations, the first gate member is located at the default position.

Abstract: The present disclosure discloses a wave-shaped polyurethane high-frequency linear vibrating screen mesh, which solves the problems of unobvious layering and poor screening effect of the existing screen mesh. The wave-shaped polyurethane high-frequency linear vibrating screen mesh comprises a side blind area and a screening area. The screen area is composed of wave-shaped injection molding polyurethane screen pieces. Materials roll forward along the direction of material flow in a wavy manner. Clamping grooves are formed in the blind area, which can be in buckle fit on rail seats of a small beam of a screening machine. The screen gap direction of the screening area is consistent with the direction of the material flow. Through the arrangement of a wave-shaped screen mesh surface, the wave-shaped polyurethane high-frequency linear vibrating screen mesh effectively optimizes the running state of the materials, and promotes effective layering of coarse and fine materials.
