An apparatus for cleaning aquaculture nets underwater. The appartus employs a propeller housing with a centrally disposed axis with a plurality of propeller blades extending therefrom. An outer perimeter ring secured to an outer tip of each propeller blade with a plurality of knuckles secured to the outer perimeter ring. Each knuckle including a curved surface constructed and arranged to strike the aquaculture net upon rotation of the blades for removal of growth by impact and shaking of the aquaculture net.

A sucker rod cleaning system includes an inductive heating device, a feed mechanism, a first support and a second support. An electromagnet of the inductive heating device includes a wire coil head that is configured to inductively heat a sucker rod positioned within a heating zone. The feed mechanism is configured to feed a sucker rod through the heating zone in a feed direction. The first support is positioned on an upstream side of the wire coil head, and is configured to support a portion of a sucker rod as it is fed through the heating zone by the feed mechanism. The second support is positioned on a downstream side of the wire coil head, and is configured to support a portion of a sucker rod as it is fed through the heating zone by the feed mechanism.

In one example in accordance with the present disclosure, an additive manufacturing platform is described. The additive manufacturing platform includes a vibrating bed on which a volume of build material is to be disposed. The bed is to vibrate to remove excess build material and operates in at least two extraction modes during a build material extraction period. The additive manufacturing platform also includes a non-vibrating frame to support the vibrating bed.

The present invention provides an apparatus for recycling artificial or synthetic layered materials. The apparatus includes a first conveying section arranged to receive and unroll a used or pre-processed roll of artificial or synthetic layered material, in use, and at least a second conveying section arranged to receive and re-roll the subsequently processed roll of said material. The apparatus further includes a beating section located intermediate said first and second conveying sections, arranged to beat and/or agitate said unrolled material as it is moved from the first conveying section to the at least second conveying section, in use.

A cleaning method that removes contaminants adhering to a stage in a chamber, includes: setting a pressure in a chamber to a predetermined vacuum pressure; supplying a first gas that forms a shock wave toward the stage; and supplying a second gas that does not form the shock wave toward the stage.

An additive manufacturing system comprises an additive manufacturing apparatus forming a molded object by curing slurry which becomes a base material of the molded object and a removing apparatus removing slurry attached to the molded object, in which the removing apparatus comprises a container having an axis of rotation and a peripheral wall provided with a plurality of small holes, the container permitting the molded object to be fixed therein, and a drive unit driving the container to rotate around the axis of rotation.

A vibration device includes a vibrator including a cylinder including an opening, a light-transmissive cover directly or indirectly coupled to the cylinder to cover the opening of the cylinder, and a piezoelectric element to vibrate the light-transmissive cover, and including an opening end portion, an elastic member holding the opening end portion of the vibrator, and a case connected to the elastic member.
