Abstract: An electrostatic spray gun apparatus includes a spray gun housing and a nozzle attached to a spray end of the housing, and a powder path that extends in a substantially straight line along an axis of the housing from the powder inlet to the powder outlet. The powder path is in the form of an enclosed smooth powder passage that is substantially continuous and uninterrupted from the powder inlet to the powder outlet to eliminate substantially all recesses or gaps that could capture or trap powder. The powder passage is formed by a plurality of tubular segments that are aligned along the housing axis and abut end to end. that when assembled in the housing axially compress the segments together to substantially eliminate dead spots or recesses to form the continuous smooth powder path. A gun purge function is provided that allows a purge line to be installed on the gun assembly. A cartridge valve and conductor assembly is provided between the gun electrode in the nozzle and the output of the voltage multiplier.

Abstract: A joystick adapter is provided for mounting over the depressible buttons of a directional keypad on a video game controller. The adapter includes a joystick having a knob and a separable base. The knob is configured for manual manipulation, while the underside of the base is configured to contact and be supported by the depressible buttons of the keypad. The knob and base are pressfit together so that the individual components can be removed and replaced. The adapter further includes a clip having a shell that is supportable on the controller body. The shell defines an opening to receive the joystick therethrough with the knob above the shell and the base between the shell and the keypad. The adapter further includes an elastic T-shaped band that surrounds the bottom and sidewalls of the controller body. The band includes three arms with resilient openings in each of the arms. The openings are adapted to engage a corresponding tab projecting from the shell of the joystick adapter clip.
