Abstract: An attachment for an air blow gun includes a nozzle and a nozzle insert. The nozzle is a hollow cylinder and includes radial pinholes at one end. The nozzle insert includes a longitudinal pinhole. The nozzle insert is inserted into the end of the nozzle with the radial pinholes. When high-pressure air is delivered to the attachment, plumes of high-velocity air exit from the radial pinholes and the longitudinal pinhole. The attachment is particularly well suited to cleaning confined spaces in workpieces with high-velocity air.

Abstract: A diagnostic tool connected to an anti-lock braking system (ABS system) is described. The diagnostic tool is capable of powering on the ABS system and measuring the load current of the ABS system while the ABS system starts up. This startup load current signature is then compared to what is considered a normal startup load current signature. Such a comparison allows the diagnostic tool to determine whether the ABS system is functioning properly or whether there is a fault with the ABS system. Additional features on the diagnostic tool also allow the tool to communicate with the ABS system via power-line communications (PLC communications) and to determine whether there are any issues with those communications. Finally, the diagnostic tool is able to receive and translate any stored or active ABS fault codes generated by the ABS system and to display those fault codes to the user.

Abstract: A scraping tip is attached to a blow gun. The scraping tip includes a neck and a head attached to the neck. The neck is hollow cylindrical and centered about a main longitudinal axis. The head has an internal cavity, a first angled face, a second angled face, a first nozzle, and a second nozzle. The internal cavity is in gaseous communication with an interior of the neck. The first angled face is in a first angled plane, while the second angled face is in a second angled plane. The first nozzle is hollow cylindrical, centered about a first longitudinal axis, merges with the internal cavity, and terminates in the first angled face. The second nozzle is hollow cylindrical, centered about a second longitudinal axis, merges with the internal cavity, and terminates in the second angled face. The scraping tip allows focused high velocity air to aid with scraping.
