A sucker rod cleaning system includes an inductive heating device, a feed mechanism, a first support and a second support. An electromagnet of 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 teed 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.

A reusable apparatus, such as a medical instrument or tool, is decontaminated by applying pressure waves with direct contact of the pressure wave applicator to the reusable apparatus in an open bath in a sufficient dosage to remove contamination but without adversely affecting the ability to reuse the apparatus.

The present disclosure relates to a method and apparatus for cleaning a 3D printed article, in particular a 3D printed heat exchanger. After 3D printing, an article may have internal passages formed from bonded powder and said passages may contain unbonded powder that needs to be removed before further use of/processing of the article. To remove this unbonded powder, the article is filled with a cleaning fluid and vibrated. The cleaning fluid is then pumped out of the article and past a sensor that generates a magnetic field. The sensor detects the presence of powder particles in the fluid by detecting a perturbation of the magnetic field caused by said particles. The fluid is then filtered and returned to a reservoir for use. The sensor may indicate the article is sufficiently clean when a detected concentration of particles in the fluid drops below a threshold.

A device and method for protecting an optical sensor of a vehicle are disclosed, wherein the sensor is protected from environmental pollutants which may adhere to an optical surface of the sensor if the sensor is exposed to them, and wherein the environmental pollutants are kept away from the sensor by an ultrasonic cleaning of the sensor surface using an ultrasonic field. The ultrasonic field of the ultrasonic cleaning is emitted by a protection device into the air to provide a protection zone around the optical surface of the sensor such that a contact of the optical surface with the environmental pollutants is avoided, wherein the environmental pollutants are moved and/or destroyed in the air away from the sensor if they enter the protection zone), and wherein the protection zone provides a contactless cleaning of the sensor.

An additive manufacturing system for producing a three-dimensional article includes a print engine, a post-fabrication powder removal apparatus, a transport mechanism, and a controller. The post fabrication removal apparatus includes a rotary frame defining an internal receptacle cavity, a plurality of clamps coupled to a corresponding plurality of actuators, a clamping plate coupled to a lift apparatus, and an agitation device mounted to the clamping plate. The controller is configured to perform the following steps: (1) Operate the transport mechanism to transport the build box to the internal receptacle cavity. (2) Operate the plurality of actuators to engage the build box with the plurality of clamps to secure the build box to the rotary frame. (3) Operate the rotary frame to rotate the build box until unfused powder begins to exit the build box. (4) Operate the agitation device to facilitate pouring of the unfused powder from the build box.
