A sieving method for separating insect pupae is described. The method may include causing an actuation system of a sieving apparatus to cycle between a first elevation and a second elevation to cyclically submerge a sieve surface of a sieving device in a liquid held within a basin so as to separate a population of insect pupae present in the sieving device with respect to size. The method may also include causing actuation of one or more valves to drain the liquid from the basin in order to retrieve a first part of the population of insect pupae.

The subject matter of this specification can be embodied in, among other things, a parts holder assembly that includes a basket having a basket floor and one or more posts each attached to the basket floor at a proximal post end and extending away from the basket floor at a distal post end, a retaining device having a frame having an open interior frame space, one or more mounting devices, each of the mounting devices being adapted to constrain the frame at a selected position along a length of a corresponding one of the posts between the proximal post end and the selected position, and a web having at least one outer edge attached to the frame and a plurality of cords extending across the open interior frame space.

A sieving apparatus for separating insect pupa is described. In an example, the sieving apparatus includes a sieving device attached to an actuation system. The sieving device includes a set of openings sized to correspond to a cross-sectional cephalothorax width of a representative pupa of a population of insect pupae to be separated. The actuation system is configured to move the sieving device in a manner that causes smaller insect pupae to pass through the set of openings. Larger insect pupae remain within the sieving device. Such movement can include moving the sieving device with respect to a liquid held in a basin of the sieving apparatus.

Example embodiments relate to devices and methods for collecting and cleaning solid substances. An example device is provided for cleaning dirt particles from a solid body. The device includes a driving shaft configured to rotate along a rotational direction. The device also includes a container arrangement that includes a first slotted container. Further, the device includes a second slotted container attached to the first slotted container and to the driving shaft via a fitting arrangement. The fitting arrangement is configured to simultaneously rotate the second slotted container within the first slotted container in a direction opposite to the rotational direction of the driving shaft.

Apparatus and method utilize an ultrasonic operation to process articles. Processing tanks are arranged serially, each having an interior extending vertically downwardly for receiving articles delivered into the tank. A plurality of baskets carry the articles to the consecutive tanks, and an overhead support arrangement at each tank receives each basket suspended from a corresponding support placed at a first location outside and above the tank. Each support is moved in a vertical direction between the first location, outside the tank, wherein the support is in position to receive a corresponding basket suspended below the support, and a second location outside the tank and below the first location, wherein the corresponding basket is placed within the tank, while the support remains outside the tank, whereby the articles are placed sequentially into each tank, while the supports remain overhead, outside the tanks, during a processing operation.

Provided herein are systems, methods and apparatuses for an immersion and spray rinsing system comprising a tank with improved cleanliness of the parts between immersion and spray.

A rinsing machine for cleaning a display panel, including a main tank body, a spillover slot at the periphery of upper edges of the main tank body, a stirrer in the main tank body, and a rinsing liquid storage slot for storing rinsing liquid used for supplementing the rinsing liquid in the main tank body is disclosed. The rinsing liquid storage slot is communicated with the main tank body via a rinsing liquid supplement valve. The main tank body is provided with a discharge port which is capable of being opened and closed at the bottom of the main tank body. A rinsing method by means of the rinsing machine is also disclosed.

A reprocessing apparatus for washing and cleaning a load comprising a reprocessing chamber, a buffer tank, a buffer tank valve and recirculation valve, fluid distribution devices and plurality of pumps, at least one ultrasonic transducer and a drainage system characterised by said buffer tank is supplied with fresh water and process chemical where buffer tank holds fresh process fluid that is pumped to at least one fluid distribution device and directly into the load, the drainage system for discharging process fluids and recirculation loop for pumping said fluid back the reprocessing chamber, and a method of reprocessing a load in a reprocessing apparatus characterised by that fresh water is mixed with process chemicals externally to said chamber in the buffer tank and delivered to said chamber through fluid distribution devices and internal connecting lines while simultaneously washing the load internally and externally and discharging the fluid from the reprocessing chamber.

A method for exfoliation of deposited material off a work piece may comprise: immersing the work piece in an ultrasonic bath and applying ultrasonic energy, wherein the ultrasonic bath contains a fluid either held at a constant temperature within the range from greater than room temperature to less than the fluid boiling point, or the fluid is cycled over a T chosen within the range between room temperature and less than the fluid boiling point, wherein the temperature is chosen to provide a significant CTE mismatch between the layer and the work piece in order to promote exfoliation of the layer off the work piece, and wherein process time in the ultrasonic bath is within a range from several seconds up to 120 minutes for loosening the layer; cleaning the work piece by rinsing with liquids; and drying the work piece. A system is described for running the exfoliation process.
