Mounting system for clay target thrower and rifle/pistol rest

An L-shaped tube has a horizontal member that fits into a trailer hitch, and a vertical member. A platform is secured to a post that fits into the vertical member. The platform has bolt holes arranged to engage a variety of commercial clay target throwers and a gun / pistol rest. A threaded dowel is inserted through the a 180 degree horizontal slot in the vertical member, and screwed into a threaded hole in the post, thereby limiting the range the platform post can swivel within the vertical member. The dowel can be tightened to lock the post between zero and one-hundred-eighty degrees. A tension cable secures the vertical member to the vehicle to attenuate vibrations. A gun / pistol rest configured to mount from the platform has a forward cradle for a gun stock or barrel, and rear mount that variously functions as a rifle-butt cradle or a pistol-butt support.

Wall separation type feedback fluidic oscillator

The invention belongs to the technical field of fluidic control of pressure gas. A wall separation type feedback fluidic oscillator is designed by combining the generated pneumatic principle with a fluid oscillator without a moving part in the pneumatic principle based manner that fluid is jetted around a curved surface in a wall separation mode. Curved wall collision jet flow has very high sensitivity, and the main jet flow is attached to the circular curved wall, collides with wall-separated jet flow at the central position, and is guided back to a wall separation control port at the upstream portion of the jet flow through a feedback pipe to form wall-separated flow. The wall-separated flow enters one side of the circular curved wall, the wall-attached main jet flow on the side is subjected to wall separation in advance, and therefore the stable wall-attached state of the main jet flow is destroyed, the collision points of the wall-surrounding jet flow on the two sides are transferred to the wall separation side, and the collision main jet flow on the two sides is switched to the wall separation side. A jet flow receiving pipe and a feedback pipe on the wall separation side are connected to a separation wall control port on the symmetrical side, and the jet flow continuously repeats the process to generate periodic oscillation. It is proved that the wall separation type feedback fluidic oscillator can be used in strengthening or controlling fluid in various aerodynamic and chemical engineering processes.
