A portable parts washer for cleaning mechanical parts that includes a washer body having an upper portion, a lower portion, and a wash basin formed within the upper portion having inner sidewalls, a floor panel and at least one drain aperture. The portable parts washer also includes an in-use reservoir formed within the lower portion of the washer body and having a bottom panel spaced from the floor panel and outer sidewalls, and which is configured to receive cleaning fluid from the wash basin through the drain aperture when the floor panel is in a substantially horizontal orientation. The portable parts washer further includes a storage reservoir formed within the upper and lower portions and which is configured to contain the cleaning fluid from the in-use reservoir when the floor panel is rotated to a substantially vertical orientation.

A portable cleaning device comprising a generally cylindrical container for receiving a fluid to a predetermined level and defining a container axis and having a bottom wall and a top opening at opposing axial ends along said container axis; a basket for supporting items to be cleaned and dimensioned to be removably receivable within said container, said basket defining a basket axis that is substantially coextensive with said container axis when said basket is received within said container and being configured to be rotatably supported for rotation on said bottom wall about said axes when received within said container; and spinning means for spinning said basket on said bottom wall about said axes when said basket is received within said container, whereby spinning said basket within said container on said bottom wall when immersed in fluid below said predetermined level creates turbulence and agitates the fluid in contact with the items to be cleaned to dislodge soil particles and contaminants from the items to be cleaned.

A cleaning device is provided with a three-dimensional circulation route for circulating workpiece holding tools that hold a workpiece, and this three-dimensional circulation route is formed by an endless conveyor chain bendable in various directions being disposed within a rectangular parallelepiped space following along the upper and lower sides thereof. The conveyor chain circulates from an upper side horizontal transport path portion via a falling side transport path portion, a lower side horizontal transport path portion, and a rising side transport path portion, and the workpiece held in the workpiece holding tools is treated by ultrasonic cleaning, shower cleaning, steam cleaning, drying and the like. Thus, it is possible to suitably dispose a workpiece transport route in a limited rectangular parallelepiped space, and carry out cleaning operations for the workpiece efficiently.

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. Corresponding computer-readable devices and systems that perform the sieving method are also described.

Techniques for depowdering in additive fabrication are provided. According to some aspects, techniques are provided that separate powder from additively fabricated parts through liquid immersion of the parts. Motion of the liquid, such as liquid currents, may dislodge or otherwise move powder away from additively fabricated parts to which it is adhered or otherwise proximate to. The liquid may also provide a vehicle to carry away powder from the additively fabricated parts. Removed powder may be filtered or otherwise separated from the liquid to allow recirculation of the liquid to the parts and/or to enable re-use of the powder in subsequent additive fabrication processes. Techniques for depowdering through liquid immersion may be automated, thereby mitigating challenges associated with manual depowdering operations.

The present invention relates to a carbide tool cleaning and coating production line and a method, including a cleaning device including a support frame, a cleaning mechanism and a drying mechanism are sequentially disposed under the support frame connected to a moving mechanism, the moving mechanism is connected to a lifting mechanism being capable of being connected to a tool fixture bracket being configured to accommodate the tool fixture; a coating device including a coating chamber which a plane target mechanism and a turntable assembly disposed in, the turntable assembly is capable of being connected to a plurality of tool fixtures being capable of rotating around an axial line of the coating chamber under the driving of the turntable assembly and rotating around an axial line thereof at the same time; and, a manipulator being disposed between the cleaning device and the coating device.

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 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. Corresponding computer-readable devices and systems that perform the sieving method are also described.

A laundry appliance includes a drum that rotationally operates within a tub. A fluid delivery system selectively delivers wash fluid to the drum. A rotator rotationally operates within the drum. The rotator selectively operates independent of the drum and about a common rotational axis of the drum and the rotator. A sanitizing mechanism includes an ultrasonic transducer. The ultrasonic transducer selectively delivers waves of an ultrasonic frequency into an amount of the wash fluid disposed within the drum and the rotator. The ultrasonic frequency generates air bubbles and causes cavitation of the air bubbles that directs a micro jet of air through the wash fluid and into articles being processed within the drum.

A cleaning device is provided. The cleaning device includes a basket-like structure. The basket-like structure comprises a wall-like portion which comprises a base. The base comprises a central portion, wherein shape, size and perforations of the base of the basket-like structure is designed to provide substantially more resistance to a fluid in the blender jar. The shape, size, and perforation of the wall-like portion is designed to provide substantially less resistance to the fluid in the blender jar. The device is a vortex enhancing device. The design of the base and the wall-like portion are capable of producing enhanced vortex in a fluid placed in the blender jar, during a working state of the blender jar.
