System and method for modular sorting stations
System and method for modular sorting stations. A sorting station may be subdivided into two or more modular bins. A modular bin may be partitioned into compartments. Each compartment may be configured to receive one order including one or more items. Modular bins may be partitioned into compartments of different sizes to receive orders of different sizes. A modular bin may be removed from a sorting station and conveyed to a packing station for packing or other sorting station to continue sorting. Picked items may be received and sorted for rebinning into the modular bins manually or using an automated sorting mechanism. A control system may direct the sorting and rebinning operation. Modular sorting stations may be located adjacent to packing stations or, alternatively, away from packing stations and, when a modular bin is complete, it may be conveyed to an appropriate packing station for packing.

Device for separating fine solid components, method of manufacturing the device, and method of separating fine solid components using the device
A device for separating a fine solid component includes a substrate and a diaphragm provided on the substrate. The substrate has a first surface and a second surface opposite the first surface. The substrate has a recess provided in the second surface, a cavity opening to the first surface, and a first through-hole allowing the recess to communicate with the cavity. The diaphragm has a second through-hole formed therein at a position corresponding to the cavity. The second through hole has a diameter smaller than a diameter of the first through-hole. This device and a method using the device enables only small solid components included in fluid having plural solid components having sizes different from each other to pass without clogging.

Vibratory separator with automatically adjustable beach
A vibratory separator having a basket for supporting screen apparatus for treating material, the basket pivotably mounted on a base, vibratory apparatus connected to the basket for vibrating the basket, the material forming a pool on the screen apparatus, and a beach formed on the screen apparatus, measurement apparatus connected to the basket and positioned above the screen apparatus for measuring a distance from the measurement apparatus to a top surface of the pool, control apparatus for controlling and in communication with the measurement apparatus for receiving signals therefrom indicative of said distance, which distance is indicative of pool depth at that location and which correspond to beach extent, and adjustment apparatus controlled by the control apparatus for adjusting angle of the basket, thereby adjusting extent of the beach.

Apparatus and method for isolating materials
Apparatus is provided for separating non-magnetic mineral values from a source containing magnetic material and non magnetic material. The apparatus includes first and second conveyers in overlying relation which counter-rotate relative to one another. One of the conveyers includes a magnetic assembly which cooperates with paddles on the upper conveyer to progressively isolate values from magnetic material. Multiple stages are provided for intermittent magnetic interactions such that the non-magnetic materials are effectively isolated from the magnetic materials.

Magnetic rake with release mechanism
A magnetic raking device that agitates a ground surface and uses magnetic attraction for collecting ferro-metallic debris, such as nails and screws, at construction jobsites and other locations, includes a release mechanism that temporarily eliminates magnetic attraction of the debris to the rake, thus allowing collected debris to drop from the rake, such as into a trash or recycling container. One type of release mechanism physically removes one or more magnets from the rake body to eliminate magnetic attraction to the rake body. One type of release mechanism uses electromagnets in the rake body that attract ferro-metallic debris when current is allowed to run through the electromagnets, and that allows the debris to drop from the rake when the current is interrupted. The magnetic rake may be used in an inverted position to attract ferro-metallic debris without agitating, and may be used in a non-magnetic state as a conventional rake.

Methods and apparatus for identifying and diagnosing live eggs using heart rate and embryo motion
Identifying live eggs includes: a) illuminating eggs with light; b) receiving light passing through each egg at a light detector; c) generating an output signal that corresponds to light received at a light detector for each respective egg; d) analyzing the output signals to identify an indication of an external disturbance; e) analyzing the output signal for each egg to identify the existence of an embryo heart rate and/or embryo movement; and f) designating an egg as a live egg in response to identifying embryo heart rate and/or embryo movement. Steps a) through d) are repeated if output signals from a predetermined number of eggs contain an indication of an external disturbance to the eggs. Steps a) through f) are repeated if the number of eggs designated as live exceeds an expected number, or if embryo movement occurs at about the same time in a predetermined number of eggs.

Conveying device having container order changing mechanism, and combination weighing device and quality inspection device provided therewith
A conveying device is disclosed that changes the order of containers during conveyance in order to speed up processes, such as a discharging process performed by a combination weighing device and a rank-order sorting process performed by a quality inspection device. With a combination weighing device, a plurality of containers placed on a rotary table are moved by rotatably driving the rotary table. While the containers are being moved, a container arrangement mechanism changes the sequential order of the containers that are specified by a control unit.
