Abstract: A method of providing scenes for use in indoor golf games having a tee, a screen in front of the tee, a means for projecting on the screen any one of a plurality of scenes taken from different locations on a golf hole, data acquisition means and a computer associated therewith for computing the trajectory of a ball hit from the tee and a ball spot projecting means responsive to the computer for projecting a spot of light on the screen and on the scenes displayed thereon to illustrate the trajectory of the ball, which method permits the use of scenes from actual golf holes taken by photographic methods and eliminates inaccuracies in the ball spot projection that would normally be present due to the uneven nature of the terrain normally found on actual golf holes.

Abstract: An induction reed valve includes a valve block with a flat end face having ports. A bulb type reed is secured overlying each port. Each reed has an outer closure portion integrally interconnected to a common mounting strip by an hourglassshaped connecting portion defining a reduced width thickness within its length and thereby reduces the spring constant and the effects of inertia as the reed moves. A stop arm is located outwardly slightly in excess of the normal full position.
